新型高效乙烯吸收剂的制备及应用研究

Study on the Preparation and Application of New Type High Efficiency Ethylene Absorbent

[目的]为果蔬的储运保鲜及对贝壳等废弃资源的有效利用提供更多的技术支撑与理论依据。[方法]分别以海螺、扇贝、花蛤的贝壳粉为主要载体制备新型高效乙烯吸收剂,并以果实硬度、可溶性固形物含量、可滴定酸含量、腐烂指数、失重率为指标研究新型高效乙烯吸收剂对蜜桃的保鲜效果。[结果]制备的3种乙烯吸收剂较对照组保鲜效果显著,均可应用于桃等果蔬的保鲜;其中以扇贝壳粉为载体的乙烯吸收剂保鲜效果最佳。[结论]采用贝壳粉作为高锰酸钾的载体,可降低乙烯吸收剂的成本,适合大面积推广。

[ Objective]To provide more technical support and theoretical basis for the storage and transportation of fruits and vegetables, and the effective utilization of abandoned resources such as shellfish. [ Method] New type high ethylene absorbent was prepared with the conch,scal-lop ,clam shell powder as the main carrier. The preservation effects on peach with new type high ethylene absorbent were investigated in this pa-per, such as the fruit firmness, soluble solids content, titratable acid, the decay rate, the weight-loss ratio. [Result] It showed that the three kinds of ethylene absorbent preservation effect was significantly higher than the control group, all can be applied to the preservation of fruits and vegetables, such as peaches. And the scallop shell powder as a carrier of ethylene absorbent had the best preservation effect of them.[Conclusion] Using shell powder as carrier of potassium permanganate, which can reduce the cost of ethylene absorbent,is suitable for large- scale promotion.
