Research development of preparation natural functional food additives from bacteria

The progress of preparation natural functional food additives from bacteria was introduced from two aspects. On the one hand is about the mechanism and health care functions of probiotics(lactobacillus and bifidobacterium),and the prospects of developing specific probiotic functional food additives for different groups of people. On the other hand is about the mechanism and health care functions of bacterial metabolites(nisin,lysozyme,polylysine),and the prospects of developing the new bacteriocin-related functional food additives.
