The research status of microbial preservatives

In recent years,a series of food safety incidents caused by synthetic chemical preservatives usage not following the regulations has been risen an extensive attention of scholars at home and abroad.In addition,the uncertainty of the toxicity,poisoning and cancer disese trigger by some common food additives are also concerned.There is an urgent need for natural and safe food additives.Microbial preservation are extracted and purified from microbes by biological engineering technology It is an antimicrobial and antiseptic action of microorganisms and their metabolic products.It is a safe,non-toxic,natural and efficient food preservatives.The research and application of microbial preservatives has become an emerging research topic which Chinese and foreign scientists have devoted much energy into it.This paper reviews the microbial preservatives's antimicrobial broad-spectrum,anti-corrosion mechanism,research and applications,such as Nisin,natamycin,e-polylysine,lysozyme,kombucha,monascus and Bacillus natto etc.This paper is intended to provide some reference for other researchers and offer proposals on microbial preservatives future research and development direction.
