Abstract 

Two different varieties of pork sausages viz. spicy and non-spicy were formulated and cooked at 
700C for 3 minutes. Both of these two formulated varieties were packaged with low-density 
polyethylene and wax paper respectively and stored under refrigeration. Sensory, nutritional and 
microbiological characteristics of both types were analysed during different storage periods viz. 
1day, 7days, 14 days and 21 days respectively. Evaluation of organoleptic characteristics showed 
greater acceptance of spicy variety in comparison to non-spicy variety. There were no significant 
variations in the nutritional composition of pork sausage varieties during storage. Microbiological 
quality of the spicy product was superior to its non-spicy counterpart. Sausages packaged in low-
density polyethylene have the greater shelf stability than that of in waxed paper after storage 
periods of 14 days and 7 days respectively under refrigerated condition. Experimental results also 
revealed that spicy formulation has greater shelf stability than that of the nonspicy formulation. 

 
Keywords: Pork sausage, Refrigeration, Storage stability, Low-density polyethylene, Wax paper.

1. Introduction 
Slaughter of animal produces a considerable amount of edible by products (head, meat, heart, tongue, tripe etc.) 

with high biological value and low palatability attributes [1]. Comminuted meat products offer an attractive 
avenue for the utilization of low-value cuts and edible offal’s by replacing a certain proportion of skeletal meat to 
reduce their cost of production [2]. The most important component of meat is the muscle in which the myofibriller 
proteins form about 60% of the total muscle protein [3]. Proteins derived from raw meat and cooked pork rind; 
exhibit a wide range of functional properties. They are able to form networks and structures, interact with other 
ingredients and thus plays an important role in the texture, sensory and nutritional qualities of foods [4].Sausage 
is a food that is prepared from comminuted and seasoned meat and is usually into a symmetrical shape [5].Fresh 
comminuted meats and ingredients used as raw materials in the formulation can be modified to yield desirable 
organoleptic and keeping qualities of the product. In sausage preparation, raw meat batters are formed by chopping 
meats along with other ingredients to form a coarse dispersion of main water, fat and protein [6].In sausages and 
restructured meats, gel formation of myofibriller proteins is responsible for retaining and stabilizing water and fat 
in comminuted meats and for binding meat pieces [4]. Collagen is the main component of skin. Collagen and other 
connective tissue proteins play a negligible role in gel formation of sausage batter. However they are typically 
included in formulations for improving water binding, processing yield, juiciness and palatability or even blend cost 
in processed meat [7-9]. Many researchers have reported the addition of starch in various sausages in forms such 
as corn and potato starch, including modified starch, for evaluation of the preparation of bologna type beef sausage 
[10] potato flour and tapioca starch for preparation of pork sausage during refrigerated storage [1] or potato 
starch in low fat frankfurters[11]. Broadly speaking the basic preparation of sausage generally involves the 
mincing, grinding or cutting of lean meat and fat, the addition of spices, curing salts or other ingredients, followed 
by filling into containers [12]. Preparation of sausages predates recorded history. Sausage making developed 
slowly, beginning with the simple process of salting and drying meats. This was done to preserve fresh meat that 
could not be consumed immediately. As the human community expanded geographically, the availability of raw 
materials and differences in climate effected variations in manufacturing procedures. As a result, the typical flavors 
textures and shapes of many sausages described day today as frankfurters, Braunschweiger, pork sausage and 
salami were produced [5].Consumers nowadays eat sausages due to its convenience, variety, economy and 
nutritional value. Sausages are economical since they were commonly manufactured from the cheaper cuts of meat 
and from by products. In fact, sausage products no doubt resulted from the attempts of primitive man to utilize for 
future use the less desirable parts and by products from slaughtering. The motto of the sausage industry wills 
might be ‘buy a pound; serve a pound’[13].Pork sausage belongs to the category of fresh sausage whereas dry and 
semidry sausages, cooked sausages, cooked smoked sausages, uncooked smoked sausages and cooked meat 
specialties were other varieties [5]. They were made from uncooked or cooked raw materials [14]. Pork sausages 
utilized head, neck, regular trimmings as meat sources and were a minced, cased product [15]. This type of meat 
products regarding emulsion type sausage was heat treated to between 750c and 800c to achieve desirable 
organoleptic properties and bacterial stability [14].They usually differ from other fresh meats in that it contains 
ground pork, salt and spices. Commonly but not necessarily, it has a somewhat short refrigerated shelf life because 
of the relatively large microbial population it contains when it was prepared from the large part of pork trimmings. 
They have a bright red color and were usually wrapped in oxygen permeable films such as cellophane, 
polyvinylchloride and polyethylene [15]. Pork sausages comprised of 30%fat [5] soy proteins, milk proteins, 
starch, wheat flour and yeast as meat extenders, (3.0-3.5)% salt [15] sucrose and dextrose as sugar [15] spices viz. 
ginger, onion, cinnamon, cloves, black pepper, coriander seed, etc.[5] and other ingredients as curing salt viz. 
sodium nitrate and nitrite or sodium nitrite alone [5] monosodiumglutamate [16] vinegar [17-19] and soysauce 
[20]. The majority of natural casings for sausages are obtained from the intestine of pigs, sheep and cattle. The 
length of gut obtained from an animal is influenced by the breed and degree of maturity [12]. Intestines intended 
for use as casings for sausages must be immediately processed after evisceration. First, they are emptied and well 
flushed. Pig, sheep and goat small intestines are scrapped thoroughly without inversion to remove the exterior 
(serous) and interior parts (mucous membrane), preserving the middle elastic muscle [15]. All salted natural 
casings should be thoroughly flushed inside with running water in the morning before use. They are then dipped 
into warm water to regenerate their elasticity (small intestines 10-20 minutes and large intestines 30-60 minutes) 
and drained for a short time before use [14]. The basic aim in cooked pork sausage manufacturing is to make a heat 
stable meat batter, a meat emulsion, consisting mainly of water and protein. Heat treatment transforms it from a 
viscous form to a rigid and elastic solid structure which can be considered as a protein gel with entrapped fat 
particles. If the protein gel is strong enough, the fat will not be separated during heat treatment [15]. The 
nutritional value of all foods including meat and meat products is being seriously considered in view of consumer 
interest and demand. Nutritional constituents of some sausages viz. mortadella polish style pork sausage, raw and 
cooked sausages, dry and cooked salami, scraple, souse, thuringer, canned vinna sausage etc. were reported 
according to Pearson and Tauber [13]. Proximate analysis of the main food components such as moisture, ash, fat, 
protein and carbohydrate and small numbers of specialized analyses based upon classical wet chemical procedures. 
In the age of more conventional food materials and simple food technology, such proximate and wet chemical 
analyses were probably sufficient for most quality control purposes [21]. The nitrogen content of meat proteins is 
about 16%, which means the protein content of meat is 6.25 times the nitrogen content [13]. A balanced intake of 
fat is essential to ensure the dietary supply of essential fatty acids and the fat soluble vitamins A, D&E [21]. 
Processed meats are considered to be high-fat foods. Fresh pork sausages and patties may have fat as high as 50% 
although the industry average is 36% [3]. High-fat contents also lead to reduced moisture content and give less 
firm sausage [22]. Moisture is the most predominant component of cooked sausages, accounting for approximately 
45-55% of total sausage weight but the exact amount varies depending on the amount added during preparation as 
well as the lean to fat ratios of the sausages [5]. The carbohydrate content of meat and meat products is usually 
negligible unless it is added during processing either as sugar or as carbohydrate material. Never the less, the 
glycogen present at the time of slaughter, although it comprises only about 1%, plays a major role in determining 
the physical properties of meat. Studies of the mineral content of meat have been largely confirmed to calcium, 
phosphorus, sodium, potassium and iron. It was reported that the content of magnesium, copper and zinc were

present in baby foods and several other processed items [13]. Microbiological quality of pork sausage greatly 
affected by Salmonella spp, coli forms, Staphylococcus aureus and some spore formers [20]. Salmonella spp may 
produce three main types of diseases i.e the enteric fevers, septicaemias and gastroenteritis [23]. Coliform bacteria 
may reach the bloodstream and cause sepsis. Certain coliform bacteria produce a potent enterotoxin resembling 
cholera toxin capable of producing acute diarrhoea, without invading intestinal epithelium. All strains of 
Staphylococcus aureus are potential pathogens. Under suitable conditions, strains produce a variety of toxins, the 

most important of which is probably α-toxin which in the animal test is lethal, dermonecrotic, haemolytic, 
leucocidal and causes platelet damage [24]. Sensory characteristics by Hedonic Rating test was used to measure 
the consumer acceptability of pork sausage. The panelist was asked to rate the acceptability of the product on a 
scale, usually of nine points, ranging from like extremely to dislike extremely scale with different ranges and other 
experiences phrases could also be used [25]. Storage of pork sausage under refrigerated condition can enhance the 
shelf stability. Storage of meat products through proper packaging arrangement is an important consideration. 
Since the cooked sausage is perishable, the storage quality of the product can be maintained in the refrigerator for 
about two week [26]. Freezing is used in the food industry to extend the shelf life of the products. However, 
during frozen storage the formation of ice crystals can occur and lead to lower binding properties in the products 
[27].The packaging requirement of meat products was further influenced by the types of processing and 
mechanizing that may be applied to them [28]. Plastic as a packaging material encompass a whole family of natural 
and manmade substances [29]. The traditional package for meats was made from various types of paperboard. 
Papers are still extensively used, but for most applications, they are coated or combined with other materials to 
improve their functional qualities [28]. Wrapping materials may also be required to provide barriers to liquid 
water, oils and greases [30]. Waxed paper is extensively used for meat packaging. Polyethylene meets the 
requirement of being a tough moisture vapor proof film which retains its flexibility at temperatures as low as -
510C. Its high porosity for oxygen was preferred for many fresh meat packaging applications [28]. Now in the 
present course of work two different varieties of pork sausages viz. spicy and nonspicy were developed and their 
storage stabilities were carried out during different periods of interval under refrigerated conditions. Sensory 
characteristics, nutritional characteristics and microbiological characteristics were also studied. 
 

2. Material and Methods 
To carry out the research pork meat purchased from Kokrajhar Market, Assam adjacent to the institution. 

Wheat flour, common salt, sucrose, soy sauce, ginger, onion, clove, cinnamon, pepper, coriander, low-density 
polyethylene, waxed paper and casing of goat were also purchased from a local market. Monosodium glutamate, 
sodium nitrate, sodium nitrate and acetic acid were collected from the food technology department of the institute. 
The methods of manufacturing of both the spicy and nonspicy varieties were represented by the following Figure 
1.

Mincing completely destroys the meat structure. Meat proteins in presence of salt, phosphate and cold water 
are dissolved forming a system consisting of a solution of salt-soluble proteins, muscle and connective tissue

particles. When fatty tissue is added the fat particles will be emulsified with the salt-soluble proteins during 
comminution. The proteins will, therefore, be able to cover the total fat surface, surrounding each fat particle and 
so stabilize the emulsion. During comminution, the structural breakdown of meat and fatty tissues occurs and a 
new system was formed i.e minced meat suspension after addition of salt, phosphate, ice water emulsion and other 
additives [14]. Here the meat and fat were minced separately in a mincer through 5mm diameter perforated plate. 
Mixer simply mixes the product to incorporate all of the ingredients [15]. Chopping was carried out by a chopper 
which was composed of a revolving metal bowl that contains the meat mass. A chopper was often used as a means 
of batching the sausage mix, the mixed batch being transferred to an emulsifier for acquiring the desired texture 
[13]. A table of the bench should be placed under the outlet of stuffing horn or stuffer to support the casings as it 
was filled and to facilitate subsequent linking [15]. In recent years final internal temperature reached in 
particularly all cooked sausages have gradually increased. Higher internal temperatures contribute to increase 
product shelf life and improved color development and stability [5].  
 

2.1. Screening of Sausage Formulations 
Pork emulsions were prepared by eight formulations e.g. A1, A2, A3, A4 and B1, B2, B3, B4 of non spicy and 

spicy varieties respectively. Quality characteristics were studied by sensory evaluation. 
 

2.2. Preparation of Ingredients 
The ingredients used in the preparation of meat emulsion and quantities were given in Table 1.

2.3 Sensory Evaluation Technique 
The product was fried in mustard oil and then served as coded samples for sensory evaluation. There was ten 

panellist including faculty members and students of the food technology department. The parameters used were 
color, flavor, texture, palatability and overall acceptability through nine-point hedonic rating test as suggested by 
Ranganna [25]. The best and appropriate two products i.e. spicy and nonspicy was selected by doing statistical 
analysis of sensory evaluation according to Watts, et al. [31]. These samples were used to proceed for storage 
stability determination under refrigeration. Both the proximate analysis and microbiological analysis were carried 
out.  
 

2.4. Nutritional Analysis  
Both the two varieties of pork sausages viz. spicy and non spicy were undergoing for nutritional analysis. The 

moisture content was determined by air drying method according to AOAC [32]. The crude fat content was 
determined according to Gerrard [12]. The moisture free sample was used to determine protein content. 
Carbohydrate content of the sample was determined by taking the sum starch and total sugars. The total ash of the 
sample was determined. For mineral contents determination, dry ashing was done and it was then used for 
estimation of calcium, iron and phosphorous. The titratable acidity was determined as acetic acid [26].The dried 
sample was used to determine the Crude fibre content according to Osborne and Voogt [21]. 
 

2.5. Microbiological Analysis 
Microbiological analysis was carried out for both varieties of pork sausages. Total colony count in terms of 

total viable organisms was determined by pour plate method according to Harrigan and Mccance [33]. Presence of 
coli form group of organisms was enumerated by MPN technique according to Refai [34]. Detection of Salmonella 
sppwas done according to Varadaraj [35]. Detection of Staphylococcus aureus, a food poisoning organism was carried 
out according to Colee, et al. [36].

3. Results and Discussions 
In this study the sensory characteristics, nutritional characteristics and microbiological quality during storage 

of different varieties viz.non spicy (A1, A2, A3 and A4) and spicy (B1, B2, B3 and B4) were determined.  
 

3.1. Sensory Characterization 
The quality of different formulations of pork sausage viz. nonspicy (A1, A2, A3 and A4) and spicy (B1, B2, B3 

and B4) were evaluated according to its major sensory attributes such as color, texture, flavor, palatability and 
overall acceptability by nine-point hedonic rating test. The result of the experimental study was shown by the 
following Figure 2 and Figure 3 respectively

Minced and seasoned meat encased in skin and cooked or preserved, mainly to be eaten cold in slices. 

Screening of sausage formulations was carried out by statistical analysis by ANOVA [31]. According to Figure 
1 formulation, A1 was mostly accepted by the panelists among nonspicy formulations and this may be due to the 
high meat content, while it was significantly different with A2 and A4 but not different with A3 at 5% confidence 
level for the parameter overall acceptability. The formulation B2 was superior among spicy formulations according 
to the panellists which may be due to mild addition of

water and fine communication lead to developing in flavor and palatability. Now for the overall acceptability, 
the formulation B2 was significantly different with B3 but not different with B1 and B4 on the basis of overall 
acceptability at 5% confidence level. according to Figure 2. So the product A1 and B2 were significantly different in 
color and overall acceptability while not intexture, flavor and palatability at 5% level of probability. Now the 
statistical analysis showed that the formulations A1 and B2 were the best among nonspicy and spicy variety 
respectively. 
 

3.2. Nutritional Characteristics during Storage 
The superior pork sausages viz. A1 of nonspicy category, B2 spicy category were stored using low-density 

polyethylene and waxed paper as packaging materials under refrigerated storage condition. After 1st day and 14th

days of storage periods, they were analyzed for their chemical characteristics viz.  moisture content, total ash, 
protein content, carbohydrate content, fat content, crude fibre, salt content, acidity and calcium, phosphorous and 
iron as minerals. The experimental results were shown in Table 2 and Table 3.

Table 2 and Table 3 showed that the proximate composition of the different varieties of pork sausages after 1st 

day and 14 days of storage periods under refrigerated condition, a slight variation in protein, fat and moisture was 
observed in case of low-density polyethylene packaging for both A1 and B2 formulations. So there were no such 
significant variations in composition. The very low water vapor transmission rate may be responsible for this result 
[37]. Moreover, a decrement of protein and fat content after 1st day and 14thdays storage period and simultaneous 
increment of moisture content after 14 days storage period were observed in both formulations. This was due to 
the fact that the water vapor transmission rate and gas transmission rate of waxed paper was significant. 
 

3.3. Microbiological Quality during Storage 
The microbiological analysis of the stored pork sausages after 1st, 7th, 14th and 21st days respectively of both 

nonspicy and spicy varieties viz. A1 and B2 were carried out for enumeration of the total number of microorganisms 
by plate count technique, Coliform count and detection of Salmonella spp, Staphylococcus aureus. The experimental 
results were shown in Table 4.

Table 4 showed that the bacteriological quality of the stored sausages. Sample B2 showed a higher initial 

population of bacteria in terms of total plate count than sample A1. Both A1 and B2 showed negative response 
during the test of coliform, Salmonella spp and Staphylococcus aureus when packed in low-density polyethylene. Both 
the spicy and nonspicy varieties packed in the wax paper showed high total plate count than low-density 
polyethylene. During different storage periods, there was an increase in the coliform count but occurrence wax 
only in wax paper packaged materials and at 14th day coliform count was observed maximum in spicy variety B2. 
Total plate count increasing rate was low in sample B2 than in sample A1 because of antibacterial properties of 
spices [5] and acidic nature of the product which may control the population of microbes [16]. Both the two major 
food poisoning bacterias viz. Salmonella spp, Staphylococcus aureus was absent in both these two categories of 
sausages. Both of them were non spore formers Weiser, et al. [38] and Frobisher and Grambtree [39].  So it was 
evident from the result that the pork sausages packaged in the wax paper could be consumed up to one week but 
the same product packaged in lowdensitypolyethylene could be consumed up to two weeks when both kept under 
refrigerated condition.

4. Conclusions 
Sensory characterization revealed that among nonspicy variety and spicy variety A1 and B2 were superior to 

other formulations due to two important attributes viz. color and overall acceptability. The shelf life of both 
categories of sausages viz. A1 and B2 were greater when packaged in low-density polyethylene than packaged in 
wax paper under refrigerated storage condition. Moreover, it was also observed that spicy sausage viz. B2 showed 
greater shelf stability than nonspicy counterpart viz. A1 in context to bacteriological stability point of view. 
Nutritional characteristics of both these two varieties of sausages were not so prominently varied during 
refrigerated storage condition and as a result, showed its health beneficial importance.
