以长角豆胶与黄原胶复配胶为涂膜基质,添加具抑菌作用的中草药制剂五倍子、大黄以及NaCl等成膜助剂,配制成中草药复合涂膜保鲜剂,用扫描电子显微镜观察此保鲜剂所成复合膜的表面形貌,并以番荔枝为实验材料,对其进行涂膜处理,研究中草药复合涂膜保鲜剂对番荔枝品质变化的影响.结果表明:中草药复合涂膜保鲜剂可形成一层致密、较均匀的膜,能抑制番荔枝果实中有机酸、VC等营养成分的消耗,降低失重率、裂果率、腐烂率和可溶性固形物转化速度,延缓后熟软化过程,抑制呼吸强度,降低细胞膜脂过氧化程度,从而延缓果实衰老,有较好的保鲜效果.

A preservative coating agent was prepared through coating matrix containing long-homed bean gum and xanthan gum with the addition of Chinese herbal extracts such as Galla Chinesis and Rhubarb, and coating accessory ingredient such as NaCl. Tight and even surface structure of this film was monitored by scanning electronic microscope. The quality change of Annona squamosa L. fruits coated with this preserving agent was also investigated. Results indicated this preservative coating agent could reduce the consumption of nutrients such as organic acid and vitamin C, decrease rates of weight loss, crack fruits and rotten fruits, decelerate transformation of soluble materials, attenuate softening process of matured fruits, inhibit respiration intensity of fruits, depress the degree of lipid peroxidation, and delay the senescence of fruits. Therefore, this preservative coating film revealed an excellent effect on fresh-keeping of fruits.
