In industrial food production, microorganisms play a critical role in the manufacturing of a variety of food substance. Food Microbiology: Microbiological analysis is important to determine the safety and quality of food. The microorganisms like bacteria, fungi can provide a beneficial role in food products like probiotics and dietary fibers, preparation of antibiotics such as penicillin, streptomycin. It could also be used in more general study of food production. allows a rapid estimation of all viable and nonviable cells. Vinegars are produced by bacterial acetic acid fermentation. See our User Agreement and Privacy Policy. They are suitable for this role because they grow rapidly, may have … Louis Pasteur showed therole ofmicroorganisms inspoilage and subsequent elucidation thatfermentation alsoinvolves microorganisms. The method that is used depends on the purpose of the testing. Microbes are very useful in creating some of the mass produced products that are consumed by people. Microorganisms are used to change one substance to another which is used as food, such as milk to yoghurt and cheese, sugar to wine and bread. Vinegars are produced by bacterial acetic acid fermentation. Identification through staining and observation of morphology also possible with DMC. Nutri Food Sci Int J. Fermentation not only gives food a good taste, texture and smell, but it causes changes that reduce the growth of unwanted food microbes. Farmers and ranchers often think of microbes as pests that are destructive to their crops or animals (as well as themselves), but many microbes are beneficial. Direct Enumeration: Using direct microscopic counts (DMC), Coulter counter etc. In fact, ester synthesis using lipase can be performed at room _____ *Author for correspondence: Tel: 91-4144-238150 E-mail: donaravind@yahoo.com . 2)Avoid Cross-Contamination- Do not cross-contaminate one food with another.
