These are the food additives that are used to preserve meat. They give desirable color and flavor to the meat. They prevent the growth of microorganism and prevent toxin formation.

Probiotics are live microbial additives that are used in many food products like fermented milk. It can balance intestinal microbial composition, reduce the serum cholesterol, improve the immunity and metabolic process, and reduce the food allergy symptom of infants. Probiotic food comprises 60%–70% of total available functional food in the market. A wide variety of microorganism is considered as potential probiotics but the predominant bacteria are Lactobacillus and Bifidobacterium species. Other probiotic species include Lactococcus, Enterococcus, Saccharomyces, Propionibacterium, and Aspergillus species. Lactic acid bacteria can contribute to safety of food, offer organoleptic, nutritional, and health advantages. Viability of probiotic microorganism is dependent on factors like food ingredients, processing operation, packaging and storage, fermentation conditions, and presence of protective agents. Lactic acid bacteria are able to produce exopolysaccharides that play a major role in the production of fermented dairy products like yoghurt, cheese, and milk-based dessert. The exopolysaccharide is used as a texturizing and stabilizing agent. Nowadays, consumers prefer safe and healthy food without additives. The exopolysaccharide has the potential for development of improved products like low fat/low milk solid yoghurt. These exopolysaccharides have anti-tumor and immune modulating capacity so with these the lactic acid bacteria have the potential for development of functional food [22].
