摘要
以‘磨盘柿’为试材,研究90%浓度的CO2气体处理10-12h对‘磨盘柿’货架期间柿果果胶、硬度、可溶性固形物、Vc、可溶性单宁、可溶性滴定酸等指标变化的影响。结果表明,CO2处理可促进‘磨盘柿’果实货架期间果胶含量、硬度、Vc含量、单宁含量的降低,可溶性固形物、可滴定酸保持稳定;CO2处理后的‘磨盘柿’果实在21天的常温货架下能保持硬脆而且完成脱涩。
In the experiment, we chose Diospyros kaki ‘ Mopan ’ as stuff. The 90% concentration CO 2 was used to treat the material. We periodically observed and analyzed the changes of weightlessness, pectin content, firmness of fruit, soluble solids, Vc, tannin, titratable acid and so on. The result showed that the treatment of CO 2 can make Diospyros kaki ‘ Mopan ’ fruit the promotion of pectin content, firmness of fruit, Vc and tannin decreased during shelf life, soluble solids, as well as titratable chemical acids could keep stable. Carbon dioxide treated Diospyros kaki ‘ Mopan ’ fruit could keep its hardness and crispness on shelves of room temperature within 21 days.
