摘要
柞蚕抗菌肽是由柞蚕体内诱导产生的一类由35个氨基酸组成的具有广谱杀菌活性的多肽化合物。人畜食用后易被体内蛋白酶水解消化而对人体无毒副作用。实验表明;柞蚕菌肽对与食品腐败有关的多种革兰氏阳性及阴性细菌均有较强的杀灭作用。在酸性条件下,其抗菌活性很强,适于大多数酸性食品的防腐,其溶解性及稳定性较好。尤其是在高温条件下仍能保持很高的活性。其作用机理不同于一般化学防腐剂的抑菌作用,而是杀菌作用,是一种对人畜无毒副作用的极有前途的新型食品防腐剂。
Cecropins of Antheraea pernyi pupae is a kind of broad-spectrum sterilizing substances constructed by 35 amino acids. It is induced from the organism of the antheraea pernyi pupae by immune ways. It has no toxic and side effects on the bodies of humanbeings and livestocks since it can be hydrolyzed by the protein enzymes easily. The experiments indicated that the cecropins has obvious sterilizing effect on many kinds of G+ and G- bacteria. It has great advantages on the preservation of acid foods for its higher effects in the acid circumstances. It has high solubility and stability and remains quite active at high tempratures. The action mechanism is to sterilize the microbes while common chemical preservatives only have antimicrobial affects. The cecropins is a new type of food preservative and has boundless prospects.
