The role of microorganisms in food preparation and beverage manufacturing is known for ages. Quave, L.C., and Pieroni, A. The products are organic acids, gases, or alcohol. Protein-containing foods, particularly meats, are putrefied by organisms (e.g., Proteus, Pseudomonas, and Clostridium bacteria) that break down the long peptide chains of proteins into amino acids and foul-smelling compounds such as amines, ammonia, and hydrogen sulfide (H2S). Fermentation ensures not only increased shelf life and microbiological safety of a food but also may also make some foods more digestible and in the case of cassava fermentation reduces toxicity of the substrate. Food microbiology focuses on studying food microorganisms. A few importance are: 1. role of microbiology in animal and food production MICROBIOLOGY Preservation of foods by fermentation (micro-organism) is a widely practical and ancient technology. This includes eukaryotes (organisms with a nucleus), such as fungi and protists, and prokaryotes (organisms without a nucleus), such as bacteria. There is a need to reduce the unacceptable levels of food borne illnesses and reduce the amount of food lost by microbial spoilage. A food microbiologist can advance to a management position through experience or by obtaining a master's degree or doctorate in the food microbiology field. Microbiologists specializing in food-based bacteria can work with the Food and Drug Administration to help identify food products that can pose a risk to human health. Food microbiology is a sub-discipline of food science that discusses the microorganisms which inhabit, create or contaminate food. The use of microbes for fermentation is Foods can be considered as a medium for microbial growth. Improperly canned foods are also subject to spoilage by bacteria, yeasts, and molds. In my fifteen years of experience in the food industry, I have understood how the microbiologic topic is relevant in production plants and it’s a very good support for resolutions that generate improvement in all the process and in the final product.
