Control of Microorganisms,The control of microorganisms is one of the major concerns of food microbiologists. This control is needed to retard or prevent spoilage and to reduce or eliminate health hazards associated with foods. The control of contaminants also aids in obtaining better results when specific microorganisms or enzymes are used in food processing.Excise 发表于 2025-3-23 23:38:58

Control of Microorganisms by Retarding Growth,actors included temperature, water activity, acidity, oxidation-reduction potential, chemical inhibitors, and microbial interactions. Besides these factors, microorganisms can be affected by electrical current (Shimada and Shimahara 1981) as well as homologous phage (Greer 1986).Anecdote 发表于 2025-3-24 17:46:22
