Aim:An experiment was conducted to evaluate the nutritional, physicochemical, microbiological, and sensory attributes of pork sausages treated with conventional smoking (CS) and liquid smoke (LS).Materials and Methods:Pork sausages were prepared by employing CS (T1) and by addition of LS at 3% (T2A), 5% (T2B), and 7% (T2C) while smoking was not done in control (C) sausages. The ready-to-eat pork sausages were evaluated in terms of proximate composition, emulsion stability (ES), cooking loss (CL), pH, water activity (aw), texture profile analysis (TPA), and shear force on the day of preparation and the shelf life of the sausages was evaluated on the basis of thiobarbituric acid reactive substance (TBARS) value, organoleptic qualities, total viable plate count, total psychrophilic count, and yeast and mold counts at 5-day interval up to 15 days under refrigerated storage (6±1°C).Results:The mean percentage moisture and percentage ether extract contents of the conventionally smoked sausages (T1) exhibited significant difference (p≤0.01) with the rest of the formulations. However, in terms of mean percentage crude protein and percentage total solids, no significant difference (p≥0.05) was recorded between the treatment groups. The mean ES (ml of oil/100 g emulsion) of the different sausage emulsions ranged from 1.88 to 3.20, while the mean aw values among the sausage formulations were found to be non-significant. In terms of mean percentage, CL and pH values, significantly lowest (p≤0.01) values were recorded by the T1 sausages. The mean TBARS values recorded at different periods of time in respect of all the treatment groups ranged from 0.10 to 0.33 mg malanoldehyde [MDA]/kg of sausages which are well within the permissible limit. The highest shear force values (KgF) were recorded by the sausages of T1 formulation (p≤0.01), while TPA of the sausages did not record any significant difference (p≥0.05) among the treatments. Organoleptic studies revealed acceptability of the sausages up to 10 days of refrigerated storage irrespective of treatments employed; however, the sausages of T1 formulation scored significantly (p≤0.01) higher panel ratings. Microbiologically, sausages with different formulations were found to be within the acceptable limit up to the 15th day of refrigerated storage.Conclusion:The study revealed that traditional hot smoking has slightly higher edges over the LS-treated sausages in terms of lipid oxidation, microbiological safety, and sensory panel ratings. However, if not superior, the same was found to be well within the acceptable limit in case of LS-treated sausages proving the potentiality of the use of LS as a suitable replacement for the traditional hazardous hot smoking process.

Aim: An attempt was made to develop a desirable meat pickle from the less tender and low demand spent chicken meat with the prime objective of its better marketability and wider acceptability amongst the non-vegetarian masses. Materials and Methods: Lean of culled spent meat was marinated for overnight and then pressure cooked and fried with spices and condiments to prepare a shelf stable meat pickle. Proximate composition, pH, TBA Values, Total viable plate count, Counts for yeast and moulds and sensory quality of the pickles were studied as per standard procedure. Results: The mean per cent moisture, crude protein, ether extract and total ash contents were 61.89&#177;0.12, 17.28&#177;0.56, 14.65&#177;0.16 and 3.35&#177;0.17 respectively. The product pH and the yeast and mould counts though did not differ significantly amongst the storage periods, yet there were significant differences (p<0.01) in TBA and total viable plate count amongst the storage periods. Organoleptic studies with score card method recorded a progressive decrease in the mean panel scores along with the increased storage periods. Conclusion: The spent chicken meat pickle was found to be acceptable for consumption up-to 90 days of storage at room temperature. [Vet World 2013; 6(3.000): 156-158

Replacement of commercial chemical preservative (Vinegar) by incorporating fermented bamboo shoot (FBS) products partially or completely and their effect on physicochemical, microbial and shelf life qualities on pork pickle products was studied. Different FBS products such as FBS extract, paste and powder were incorporated in the pork pickle products at the level of 50 to 100 % with or without vinegar and stored at room temperature for 90 days. Highest pH values and lowest titrable acidity was recorded in products with 50 and 100 % FBS powder. No significant differences were observed with respect to proximate composition i.e. percent moisture, protein, fat and ash contents among the products except the product with 100 % FBS powder which had significantly (p<0.01) lower moisture content. Microbial load (Log total plate counts) and thiobarbituric acid (TBA) values were found to be increasing as the storage periods were advancing. Except the product with 100 % FBS powder which could be stored for 30 days only, other products could be stored upto 90 days without any physicochemical and microbial problems. It can be concluded from this study that natural and organic FBS extract and paste can be used successfully replacing the conventional chemical preservative (Vinegar) for preparation of pork pickle products and preserved more than 90 days at room temperature. However, FBS powder can be used for preservation of the pickle products for a short period (30 days).

Mozzarella cheese is an extremely versatile product that has been widely used by the food sector as an essential ingredient in pizza, cheeseburger, cheese-based salads, etc. The main aim of the present investigation is to study the effect of coagulating enzymes and types of milk on the physico-chemical, proximate composition and sensory attributes of iron fortified mozzarella cheese. Iron-fortified mozzarella cheese was prepared using chymosin (control group) and kiwifruit crude extract (treatment group) from three different types of milk (cow milk 100%, goat milk 100%, and cow: goat milk 50:50 ratio). SDS-PAGE of kiwifruit crude extract exhibited protein bands at 24.5 kDa, 20.3 kDa, and 18.8 kDa. The milk clotting time of kiwifruit crude extract exhibited a shorter coagulation time in the presence of CaCl2. Highly significant (p<0.01) difference between enzymes, types of milk, and the interaction effect between enzymes and types of milk were noted for pH. Similarly, a highly significant difference (p<0.01) was observed between types of milk and interaction effect between enzymes and types of milk while a significant difference (p<0.05) was observed between enzymes for titratable acidity. The highest moisture and fat content were noted in the control group for goat and mixed milk cheese while fat, ash, and TS were comparably higher in the treatment group in mixed and goat milk cheese samples. The sensory score of mixed milk cheese enjoyed the maximum ratings by the taste panel members. Based on the findings, the present study suggests that mixed milk iron fortified mozzarella cheese (treatment group) was adjudged the best product compared to cow milk or goat milk mozzarella cheese
