复合中草药提取剂在鸭梨保鲜中的研究

Effect of composite herbal extract on fresh-keeping of Ya-pears

目的:以鸭梨为原料,探索复合中草药提取物对鲜切鸭梨保鲜效果的影响。方法:分别用70%、80%乙醇在超声波震荡提取方法下对黄连、丁香、桂皮进行了有效成分的粗提,分别在50、100、200倍稀释浓度条件下将粗提液经过蒸发浓缩成中药原液配制成浸泡液;采用1:1:1的混合比例,将3种中药原液混合配成复配药液依上述方法稀释得到浸泡液。利用这4组不同药液对鸭梨进行保鲜试验。结论:结果表明,提取液在降低失重率、腐烂率,维持鸭梨总糖、总酸、Vc、可溶性固形物等营养成分上效果明显,均优于对照,且FP液保鲜效果也好于单一提取液对鸭梨的保鲜效果,因此FP液可作为天然保鲜剂应用于鸭梨的保鲜。

Objective： Ya-pears were considered as raw material, composite herbal extract effect on the preservation effect of Ya-pears need be explored. Method： The experiments were conducted with 70%, 80% ethanol in the extraction method of the ultrasonic vibration berberine, clove, cinnamon and the active ingredient for the crude extract, respectively, in 50-fold, 100-fold, 200-fold dilution of the crude extract after the condition was evaporated condensed into a liquid medicine configured soaking. Which used a mixing ratio of 1：1：1, the three Chinese medicinal herb liquid which were dubbed to complex mixing liquid diluted in accordance with the above method to get soaking. Use of this liquid on four different fresh pear conduct tests. Conclusions： The results showed that： extract in reducing weight loss, decay rate, maintaining pear total sugar, total acid, Vc, soluble solid contents and other nutrients has obvious effect than the control, and the effect of FP was better than a single extract fresh preservation of pear, so the FP solution can be applied as a natural preservative of pear.
