Atmospheric gases include oxygen, carbon dioxide, Nitrogen and Argon. During packing, atmospheric gases can be modified by altering the gases around the food. The presence of oxygen can lead to spoilage of food due to aerobic microorganisms. Conventional methods may create a loss of quality and taste. Chemical changes like rancidity, color, flavor loss, and oxidation are the major problems that occur in most traditional and conventional preservation methods (Rahman & Velez-Ruiz, 2007). The significance of modified atmosphere packaging (MAP) lies in its ability to preserve perishable products by creating an atmosphere that differs from the typical conditions. This technique ensures the food safety (Hintlian & Hotchkiss, 1986). This technology makes the food safe to use. Food Safety Concern MAP lacks the ability to ensure food safety directly. It increases the time a product can be stored by slowing down the harmful biochemical and microbiological changes that can affect its safety (Soltani et al., 2015). Numerous organisms exhibit accelerated development in the presence of aerobic organism growth. By providing an appropriate amount of gas mixtures, the proliferation and viability of several bacteria that are accountable for the deterioration of food products can be decreased (Soltani et al., 2015). These organisms themselves or by producing toxins can cause food poisoning and even threaten human life. (Han et al., 2018) However, MAP minimizes the activities of spoilage organisms that normally give warning for potentially unsafe conditions (Sandhya, 2010). Reduced oxygen packaging can lead to botulism caused by Clostridium botulinum by providing anaerobic conditions for its growth. In the fresh-cut industry, the significance of pathogenic bacteria cannot be neglected. A good packaging material is essential for MAP packing to ensure food safety (Larson et al., 1997). A Study conducted by Djordjevic et al. (2018) demonstrated the impact of MAP packaging on minced meat. MAP packaging with 50% of carbon dioxide showed a reduction in salmonella count (Djordjević et al., 2018). Several studies showed that MAP significantly reduces the presence of E.coli, Salmonella spp., Listeria, and Campylobacter, but the main concern is Clostridium botulinum, a dangerous bacterium responsible for foodborne illnesses. Food safety in MAP is ensured using correct gas mixtures (Caleb et al., 2013). Food Preservation Preservation is extending the shelf life of products by preventing spoilage by microorganisms while maintaining nutritional values and quality. There are many preservation techniques (Kumar, 2019). Massive food waste results in poverty and starvation every year. However, preservation techniques aims at reducing the decomposition of food by microbes and other means (Kumar, 2019). Traditional Methods The traditional methods used for preserving food include; Sun Drying This is the most ancient type of preservation. Sun drying utilizes solar heat and movement of surrounding air to evaporate water from food items (El Hage et al., 2018). Pa ge 2 https://journals.e-palli.com/home/index.php/ajfst Am. J. Food. Sci. Technol. 4(1) 1-10, 2025 Curing The moisture content in the product is reduced by the osmosis process. The reduction in moisture content results in reduced microbial activity (Hamada et al., 2022). Canning Canning is the process of packaging food in sterilized containers and subjecting it to high temperatures to extend its shelf life. This process eliminates spoilage microorganisms and pathogenic bacteria, enhancing food’s nutritional and physical quality (Rajput et al., n.d.). However, the anaerobic bacteria Clostridium is a threat to canned foods (André et al., 2017). Refrigeration Refrigeration is the preferred method for preserving fresh, high-value commodities due to its minimal impact on food properties at 4°C. However, continuous monitoring and regulation of environmental conditions are required to achieve optimal results (Tuan Pham, 2014). Freezing Freezing is a common and effective method for preserving food’s taste, appearance, and nutritional value by lowering the temperature to -40°C, as it inhibits chemical reactions, prevents microorganism growth, and reduces cellular metabolic activity (Sutariya & Sunkesula, 2021). Addition of Sugar and Salt Preserving food products by adding sugar and salt is a traditional method. However, sugar and salt act as a natural preservative to increase sugar content in the food, leading to hypertonic conditions. This process reduces the water and makes the environment unfavorable for microbial growth. This preservation method is primarily used for preserving fruits (S, 2020). Boiling or Thermal Treatment It is a method of preserving food by inhibiting enzymes, toxins, and harmful microorganisms. It is one of the oldest methods, while blanching is a milder method that reduces oxygen content and inactivates enzymes (Dewan, 2020). Pickling The foodstuff is immersed in vinegar, oil, or brine. Due to anaerobic fermentation, lactic acid and acetic acid are formed and act as preservatives (Aljahani, 2020). Fermentation It is a vital metabolic activity that occurs without oxygen, primarily using sugar. It produces alcohol, gases, and organic acids as byproducts. The microbe’s activity during fermentation reduces the product’s pH and inhibits the growth of undesirable pathogens (Mani, 2018). Modern Methods For preserving and ensuring food quality, following modern methods are used; Pasteurization It is a vital preservation technique that ensures food safety. The primary objective of pasteurization is to eliminate microorganisms that cause food spoilage and potential hazards to consumers’ health (Ramesh, 2020). Chemical Food Preservatives Anti-microbial chemical substances can be added to food to extend the shelf life. The addition of chemical food preservatives in large quantities can be toxic. Benzoates, nitrites, propionate, sulphites, and sorbates are some food preservatives. Certain chemicals may cause allergic reactions and other serious health problems, including cancer (Gupta & Yadav, 2021). Freeze Drying It is a process that uses low pressure to convert ice into water vapor and remove it from a substance. Freeze drying eliminates 98-99% of water content in food. This process limit the availability of water to microorganisms hence ensuring food safety (Gaidhani et al., 2015). Vacuum Packing Oxidation can be avoided by excluding oxygen from the packaging system through vacuum packing and high- barrier packaging materials (Patil et al., 2020). This process can eliminate spoilage microorganisms and ensure food safety. Bio-Preservation Utilizing beneficial or fermenting bacteria against the pathogens is bio-preservation. Bio preservatives can produce toxic chemicals detrimental to pathogens (Singh, 2018). Irradiation Food irradiation is a method of exposing food to ionizing radiation, breaking chemical bonds and potentially exposing harmful microbes in meat, poultry, and seafood. It is used as a preservation method because it can de- infest spices, increase the shelf-life of fresh fruits and vegetables, and inhibit the sprouting of tubers and bulbs like potatoes and onions (Joshua Ajibola, 2020). Hurdle Technology It is a revolutionary concept that combines various preservation strategies to produce safe, nutritious, and economical food. It involves salt, lowered pH, reduced water activity, heat treatment, and adequate packaging. Hurdle technology was invented to ensure a reasonable shelf-life, acceptable taste, and desired consistency (Singh & Shalini, 2016). This review aimed to provide a comprehensive overview of modified atmospheric packaging usage across various products and underscores the significance regarding food safety and preservation. MATERIALS AND METHODS Recent studies and reviews of publications and articles Pa ge 3 https://journals.e-palli.com/home/index.php/ajfst Am. J. Food. Sci. Technol. 4(1) 1-10, 2025 pertaining to food packaging and preservation were taken into consideration for this review. The study aimed to evaluate the efficacy of modified atmosphere packaging on different food products. Data was collected from electronic databases, including Google Scholar, Web of Science, Hindawi, Research Gate, Science Direct, and FSTA. Studies were selected from different years ranging between 2010 to 2024 using keywords’ packaging,’ ‘food packaging,’ ‘food preservation,’ ‘food preservation techniques,’ ‘food packaging and preservation,’ ‘modified atmosphere packaging,’ ‘MAP and food preservation,’ ‘packaging methods.’ RESULTS AND DISCUSSION Result A total of 65 articles are included in this review from last 15 years highlighting the effectiveness of modified atmosphere packaging on various food products. Discussion Modified Atmosphere Packaging The MAP is a method that alters the atmosphere around food during packing, ensuring safety and quality. It uses various gases, such as oxygen, carbon dioxide, nitrogen, and argon, in the best combinations to maintain the product’s quality, as shown in Figure 1. MAP is a rare commercial-scale preservation technique that helps maintain quality and safety (Khan & Mittal, 2020). The application of MAP on various food products for food preservation dates back to 1927. Later, when meat carcasses were shipped to UK, it was used in Australia and New Zealand. The commercial application of this technology was first introduced in fruits and vegetables (Sebranek & Houser, 2017). The technology helped to double the shelf life of apples and pears. Later modifications were made to the technology for better results, including micro-perforation, anti-fogging layers, etc. (McMillin, 2020). In the past few years, there has been a considerable increase in the range of foods packed under MAP. Apart from fruits and vegetables, meat, poultry, fish, bacon, cakes, sweets, salad, sandwiches, snacks, and ready meals are among them (McMillin, 2020). Figure 1: Modified atmosphere packaging of fresh fruit Gases Used in MAP MAP uses three main gases: carbon dioxide, oxygen and nitrogen. Carbon monoxide, argon, methyl cycloprene and sulphur dioxide are also used in some foods (Mullan & McDowell, 2011). These gases can be used in combinations. However, the selection of gas depends upon the food selected to pack under MAP, as shown in Table 1. Carbon dioxide actively eliminates bacteria and moulds. About 0.03% carbon dioxide is present in the atmosphere. The increased concentration of this gas helps prevent spoilage and extend shelf life by slowing the growth of spoilage and pathogenic bacteria (Zahra et al., 2016). The higher concentration increases the acidity in moist foods due to its solubility in water. Solubility increases with a decrease in temperature, which shows antimicrobial properties at low temperatures. However, the common disadvantage is a collapse of packaging due to gas formation (Zahra et al., 2016). Oxygen is responsible for the oxidation of oil and fat in food products, providing favorable conditions for the growth of aerobic bacteria and mould. The amount of oxygen in the atmosphere is 21%. Reducing the oxygen level in gas combination is advisable to reduce the aerobic bacterial growth because most of the bacteria and fungi grow in aerobic conditions. Oxygen promotes several types of deteriorative reactions, including oxidation, browning, and pigment oxidation. However, complete elimination of oxygen may lead to anaerobic or facultative bacteria growth, which can lead to food poisoning (Zahra et al., 2016). Nitrogen is an inert gas. This is the most abundant gas in the atmosphere with 78%concentration. The presence of nitrogen prevents package collapse in MAP processing, which occurs in the presence of a high concentration of carbon dioxide. Typically, the residual gas combination is mainly comprised of nitrogen (Alwazeer, 2019). Argon is a noble gas with antibacterial properties. It is currently used in MAP due to its atomic size being similar to molecular oxygen, making it a potential substitute for nitrogen. The atmosphere contains 0.9% argon (Day, 2007; Han, 2005). Pa ge 4 https://journals.e-palli.com/home/index.php/ajfst Am. J. Food. Sci. Technol. 4(1) 1-10, 2025 Types of MAP There are two main methods for creating MAP; Active Packaging This is done by draining all the gases in the package and creating a vacuum. Then, substituting the required gas combinations. This can be established by using ethylene scavengers or emitters. Active packaging helps to create a modified atmosphere very rapidly (Robertson, 2009). Passive Packaging Modified atmosphere is passively generated inside a sealed package due to product respiration utilizing oxygen and releasing carbon dioxide. This is, therefore, known as commodity-generated MAP (Costa et al., 2011; Parry, 2012). Equipment for MAP The selection of appropriate equipment is a major criterion for modified atmospheric packing: • Presentation • Machine performance • Versatility • Pack format • Operation cost • Quality and ease of cleaning • Equipment price Form-filled seal machines, Chamber machines and snorkel machines are frequently used (Rao, 2015). There are two categories of MAP machines; Pillow Wrap The pillow wrap machines are made of two systems: horizontal form fill seal (HFFS) and vertical form fill seal (VFFS). Chamber Two different techniques are used in chamber processing: The thermoforming technique and the preformed container machine. The thermoforming machine is widely used, as shown in Figure 2. The machine is fed with two films, one for forming the tray base and the other for the lid. The food is placed on the tray after it is ready by heating in the thermoforming station. Then, a vacuum is created, and the gas mixtures are flushed before closing the lid. Then, the product is sealed with film. Table 1: Gas combinations and concentrations of MAP Food Items Percentage of different gases Remarks Oxygen Carbon di Oxide Nitrogen Fruits 3-5% 5-20% 75-85% Oxygen should be in low concentration to reduce the post-harvest respiration and transpiration Vegetables 3-5% 5-20% 75-85% Oxygen should be in low concentration to reduce the post-harvest respiration and transpiration Red Meat 60-65% 15-40% --------- Oxygen gives red colour. Processed meat ------- 20-35% 65-80% Fish 30% 40% 30% For fatty fish, nitrogen concentration can be increased. Poultry ------- 25% 75% Oxygen may lead to greyish tinges on meat. Ready Meals 10% 40% 50% Minimum level of oxygen needed to prevent anerobic bacteria. Dairy products ------- 30% 70% Oxygen causes oxidative rancidity. Figure 2: Thermoforming Equipment Pa ge 5 https://journals.e-palli.com/home/index.php/ajfst Am. J. Food. Sci. Technol. 4(1) 1-10, 2025 1. The film necessary to form the bottom of the package is wound on a real machine equipped with a special device to ensure constant film tension during every machine repeat. 2. The film is heated in the pre-heating station and enters the forming station, where a perfect forming suction is made with the pump. 3. The packs are manually or automatically filled. 4. The top film is unwound to cover all packs and can be printed. 5. The package is sealed, and vacuum, and gas flushing are occurring. 6. The perfect shape of each pack is carried out at this cutting station. 7. The motorized outlet conveyor mesh brings the pack out of the machine. Preformed container machines are almost similar to each other; the only difference is that here, the preformed trays are loaded to the machine. Packing Materials Used in MAP Plastic is the common choice for packaging food, but it is not eco-friendly. Polymeric films are used to pack fresh produce. Commonly used polymeric films are LDPE, LLDPE, HDPE, PP, PVC, polyesters, PET, PVDC, EVOH, Nylon, PCTFE, PVOH, PVOH, EVA, polycarbonate films, polystyrene, cellulose-based plastics, and biodegradable polymers. Sometimes, to achieve all the good properties of a packing material of MAP, a combination of materials also are used (Mangaraj et al., 2009). Biodegradable Packing Materials Bio-based packing materials have been introduced to reduce the environmental issues due to the use of petrochemical products for packaging. Innovative packing materials definitely enhance the sustainability (Reichert et al., 2020). Biodegradable packaging materials have a good barrier property and increase the shelf life of the packed products while helping in biodegradability. Biomers can be produced using different methods: directly from natural substances like polysaccharide proteins, polymerization of monomers derived from biomass such as PLA from lactic acid and microorganisms such as polyhydroxyalkanoate (PHA) (Thulasisingh et al., 2021). Poly Lactic Acid (PLA) PLA is an aliphatic polyester with biopolymer properties suitable for MAP. It is a biodegradable and compostable thermos plastic polymer. This is produced by fermentation and distillation process from starch. The PLA will break down within twelve weeks compared to plastic, which takes centuries to degrade. Hence, PLA is environment- friendly (Tawakkal et al., 2014). Types of Polymeric Films for MAP Three types of polymeric films for MAP are developed; 1. Micro perforated or non-perforated films 2. Macro perforated polymeric films 3. Perforation-mediated packaging systems Micro-perforation allows the proper carbon dioxide and oxygen concentrations in the package headspace to extend shelf life. The gas permeability in this type is controlled by the number of perforations and their size. By adjusting the size and density, the packing films can be customized for specific products (Hussein et al., 2015). Normally, the perforation size is 50 to 200 micrometers in diameter. Conversely, macro perforation has a higher permeability rate than micro-perforated materials. This is a simple technique that involves only punching, which helps in better gas diffusion. Perforation-mediated packing system offers the benefit of avoiding in-package anaerobiosis, extending the shelf life and maintaining the quality of fresh or minimally processed produce (Hussein et al., 2015; Winotapun et al., 2015). Selection Criteria for Packing Material for MAP 1. Type of packing whether it is flexible, rigid or semi rigid. 2. Permeability or the barrier properties. 3. Machinability and strength 4. Clarity 5. Durability 6. Heat sealing property 7. Extend of fogging especially when transpiration occurs in fresh produce. 8. Sealing reliability 9. Rate of water vapor transmission 10. Resistance to chemical degradation 11. Chemically inert 12. Non-toxic 13. Commercially suitable 14. Economic feasibility. Table 2 presents the packaging materials and their properties used during MAP. Table 2: Various packing materials used in MAP LDPE (Low density polyethylene) • Soft, flexible and strong • Resistance to chemicals • Easy to seal • High oxygen and carbon dioxide permeability • Low cost PE • Strong, flexible, tough • Good barrier properties • Not suitable for application involving exposure to heat. • Low cost Pa ge 6 https://journals.e-palli.com/home/index.php/ajfst Am.

Some species can cause food deterioration, while others can cause food poisoning during storage. MAP can alter these growth patterns, increasing shelf-life by adjusting the gases needed. Furthermore, oxygen is a significant factor in bacterial growth, which can be classified based on oxygen demand. Aerobes Which require oxygen for growth and development. Microaeropliles They need a low concentration of oxygen. Some pathogens can grow optimally in such conditions. Facultative Aerobes They can grow better in oxygen but survive without it. Many strains are psychrotrops. Pa ge 7 https://journals.e-palli.com/home/index.php/ajfst Am. J. Food. Sci. Technol. 4(1) 1-10, 2025 Anaerobes They cannot live in the presence of oxygen. Complete removal of oxygen in MAP may not be useful for shelf life extension because pathogenic bacteria like Clostridium may survive, which can cause food poisoning. Consequently, carbon dioxide, when present in a minimum of 20% concentration, may indefinitely extend the lag phase of microorganisms while exerting bactericidal effects on the bacteria and molds, making it the most commonly used gas to limit bacteria and mold growth (Yan et al., 2022).Biochemical changes with MAP Lipid Oxidation Unsaturated fatty acids oxidize when exposed to oxygen, and the rancidity process accelerates. The reaction is caused by oxygen joining with unsaturated fatty acids. Removing oxygen and replacing carbon dioxide and nitrogen will dissuade rancidity in food products (Laguerre et al., 2020). Discoloration of Meat Red color of meat is preferred by the customers, which occurs due to the presence of oxy-myoglobin. MAP in the opaque pack is suitable as light can cause discoloration due to chemical changes. Low oxygen concentration is advisable in cured meat for color retention (Cenci-Goga et al., 2020). Oxidative Off Flavor Usually, this occurs during chilled storage. Meat, poultry, fish, and dairy products are highly susceptible to oxidative processes. MAP can delay developing off orders at low oxygen concentrations (Gorris & Peppelenbos, 2020). Photo-Oxidation of Chlorophyll Oxidation of chlorophyll occurs in fruits and vegetables, which turn green to brown or grey. Low-concentration and opaque packets can reduce this effect in MAP (Mullan & McDowell, 2011). Physical Changes The following physical changes can occur in food products during packaging. Therefore, MAP helps to reduce physical changes in food. • Spoilage • Water Loss • Wilting • Weight Reduction • Textural Changes • Syneresis in Dairy Products Role of Modified Atmospheric Packing in Achieving SDG’s The role of technology in sustainability is clearly understood here. MAP can contribute to many sustainability development goals, such as SDG 2: zero hunger, SDG 12: Responsible consumption and production, and SDG 13: Climate action set by the United Nations (Lemaire & Limbourg, 2019). Food waste is a significant issue globally, with billions of tons wasted daily. However, one-third of this waste comes from production (Lemaire & Limbourg, 2019). MAP technology aims to minimize food waste and extend shelf life, contributing to sustainability goals like zero hunger. Responsible production involves reducing chemicals and synthetic materials, achieving SDG 12. MAP also introduces biodegradable packing materials, promoting an eco-friendly system. By reducing plastic packaging and increasing shelf life, MAP technology contributes to environmental sustainability and SDG 13 (Lemaire & Limbourg, 2019). MAP of Fruits and Vegetables Passive MAP minimizes respiration rates in fruits and vegetables, which have high perishability, rapid quality decay, and limited shelf life. MAP helps delay post- harvest ripening and prevents early spoilage (Oliveira et al., 2015). It is widely used in fresh-cut farm produce, maintaining TSS, juice content, and surface color. MAP can also prevent enzymatic browning in high oxygen concentrations (Tinebra et al., 2021). Various studies showed that MAP can retain quality in plums, strawberries, kiwi, litchi, table grapes, cherries, and blueberries. MAP can also reduce water loss and wilting in green leafy vegetables like spinach, parsley, and dill and help retain chlorophyll (Soltani et al., 2015; Thompson et al., 2018). MAP of Poultry and Meat Meat is a highly perishable product, and minced meat is susceptible to bacterial growth due to the disruption of meat’s cellular structure throughout the surface. Due to cross-contamination, meat can be contaminated with Salmonella during slaughter, dressing, deboning process, transportation and storage. Therefore, MAP technology was used to decrease the count of Salmonella in minced meat (Djordjević et al., 2018). MAP is a technology used to preserve the color of fresh meat cuts by maintaining the pigment even in an oxygen-rich environment. This process is particularly useful for sliced beef, a quality criterion that commands high market prices (Singh et al., 2011). The primary cause of red meat deterioration is microbial growth and oxidation of the oxymyoglobin pigment (Bekhit et al., 2019). However, the oxygen level must be decreased to prevent microbial proliferation, while maintaining a low oxygen concentration is crucial (Danijela et al., 2013). MAP ensures the appropriate concentration of gases, inhibiting microbial growth and preserving the product’s color (Gill, 2018). Further, poultry primarily focuses on prolonging its shelf life, and MAP treatment has shown a significant reduction in bacterial growth (Ibrahim et al., 2020). Moreover, chilled storage and nitrite as a preservative can also reduce post-processing contamination in meat and poultry products. Thus, prevent food spoilage and poisoning (Papadochristopoulos et al., 2021). Pa ge 8 https://journals.e-palli.com/home/index.php/ajfst Am. J. Food. Sci. Technol. 4(1) 1-10, 2025 MAP of Fish and Seafood Aquaculture has become a global phenomenon, with fish and shellfish being highly perishable due to bacterial action. Typical icing and refrigeration methods only extend shelf life by a few days. Aerobic microbes spoil processed fish, leading to spoilage. MAP inhibits spoilage flora, increasing shelf life significantly (Kontominas et al., 2021). Microbes are found in fresh catch’s surface, gills, and intestines, causing spoilage quickly. Chemical changes, such as auto-oxidation or enzymatic hydrolysis, can result in off orders in fish (Tavares et al., 2021). Tissue enzyme activity can also lead to unacceptable softening. Trimethyl Amine Oxide (TMAO) in fish muscle can be degraded to TMA at chilled temperatures, causing a spoiled fish smell (Debbarma, 2022). Studies on seasoned cobia sticks show that cobia sticks remain safe and of good microbiological, chemical, and biological quality for a longer period when packed in MAP. The extended shelf life of fish depends on species, fat content, initial microbial load, gas mixture, and storage temperature (Gonçalves & Santos, 2018). Despite a smaller shelf life, high demand for spoiled fish products persists. MAP of Dairy Products Milk-based products, such as sweets, fat-filled milk powders, cheese, and fat spreads, are in high demand due to their high consumption (Oliveira et al., 2019). However, these products suffer from spoilage due to oxidative rancidity and microbial growth. They have limited shelf life due to deteriorative changes during storage. These products are mainly consumed fresh and undergo biochemical, physical, and microbiological changes, making them unfit for human consumption (Lu & Wang, 2017). MAP has been studied to enhance the shelf life of these dairy products. Cheese products can be packed using MAP, as the combination of gases ensures shelf life and quality, maintaining the seal tight without excessive pressure on the packing seal (Atallah et al., 2021). Future Prospects Many novel technologies, such as active packaging and hurdle technology, are associated with MAP products to increase safety and shelf life further. Active packaging is an emerging technology in which food packages and the environment interact using gas emitters and absorbers. Hurdle technology is a combined process that is an intentional combination of preservation techniques in order to establish a series of preservative factors (hurdles) that any present microorganism cannot overcome. It can be a storage temperature, water activity, pH, redox potential, bio conservation, MAP, Ultra pressure treatment, and edible coatings. The use of combination processes with MAP is nascent and needs further development. Furthermore, smart packing, such as TTI (time-temperature indicators), is a technology that can be combined with refrigerated MAP products. This ensures food safety with strict temperature control over time. CONCLUSION In conclusion, this study underscores the significance of modified atmosphere packaging for various products. MAP technique is crucial for food preservation, preventing food waste and ensuring food security. MAP is a modern preservation technique that helps extend the product’s shelf life by retaining its quality and flavor. It reduces food waste, extends shelf life, and maintains nutritional value. MAP is linked to zero hunger, responsible consumption, and climate action goals in sustainable development. It is versatile and effective for various food products, including vegetables, fruits, meat, poultry, fish, and dairy. For all these products, MAP has proved to provide significant barrier properties and improved shelf life to a longer extent. MAP is not only a solution for food preservation but also accelerates the future demand for environmentally friendly packaging materials and technologies. Limitations and Strengths The study limitations may include generalizability and study selection bias. However, this review highlights the use of MAP in food preservation, its application across various food categories and its relevance to SDGs. It provides a comprehensive overview of MAP technology and its practical implications for stakeholders in the food industry. REFERENCES Aljahani, A. H. (2020).
