Microorganisms are found everywhere - in the atmosphere, in water, on plants, animals and in soil. Because they break down organic material, they play an important role in the cycle of nature. Microorganisms occur most abundantly where they find food, moisture, and a temperature suitable for their growth treatment in which food is heated to <100°C. It is widely used throughout the food industry and is frequently employed as a CCP in various HACCP plans. As a unit operation in food processing it can be used to destroy enzymes and relatively heat sensitive micro-organisms (e.g. non spore forming bacteria, yeast and moulds) of specific microorganisms [7,8]. Milk products also serve as the important delivery vehicles for probiotic bacteria. The probiotic bacteria have a long history of association with dairy products [9]. Now a day, milk processors used dairy starter and enzymes/rennet for dairy product production/manufacture A strong and dynamic food processing sector plays a vital role in reduction in the wastage of perishable agricultural produce, enhancing shelf life of food products,ensuring value addition to agricultural produce, diversification &commercialization of agriculture, generation of employment, enhancing income of farmers and creating surplus for the export of agro & processed foods Introduction. Contamination by microbial food-poisoning agents may occur at various stages in the food chain. Contaminants can be present in raw products (animal or vegetable) prior to harvesting or they may gain access during slaughter or processing, by the addition of contaminated food ingredients or processing aids, from the factory environment or by cross-contamination from other. The Benefits of Microorganisms For the human being are multiple. From applications in the food industry, to the processes of solid waste degradation or the development of vaccines and medical advances. Microbes or microorganisms are small microscopic entities that can be classified into different groups, such as bacteria, fungi, protozoa, microalgae and viruses
