最近 ,美国研制出一种用于水果的新的生物防腐剂 ,它是由改良的紫胶和蔗糖酯类构成 ,是糖和脂肪酸的衍生物。该生物防腐剂形成的衣膜能促进水果表面自然存在益菌和酵母菌的生长 ,从而帮助保持水果的质量。该生物防腐剂防治水果腐烂的机理是水果表面的有益微生物与引起水果腐烂 Recently, the United States has developed a new biocidal preservative for fruits that is composed of a modified shellac and sucrose esters and is a derivative of sugars and fatty acids. The bio-preservatives form a film that promotes the growth of naturally occurring probiotics and yeasts on the fruit surface, helping to maintain the quality of the fruit. The biological preservatives prevent fruit rotting mechanism is the beneficial microorganisms on the surface of the fruit and cause fruit rot
