Thermal Methods of Postbiotics Preparation

Postbiotics are biologically active probiotic microorganisms that produce nonviable bacterial products or metabolic by-products. Postbiotics are low molecular weight soluble chemicals produced by living microflora or released after microbial cell lysis that are by-products of this metabolic sequence. Thermal processing of foods is used to minimize or eliminate microbial activity, reduce or destroy enzyme activity, and generate physical or chemical changes in order to achieve a certain quality standard. Pasteurization, sterilization, ohmic heating, and microwave heating are all thermal methods. These methods are used to break down bacterial strains. The present investigation analyzes thermal treatment, which is a widely utilized and low-cost approach.
