摘要:

以沂州木瓜为试材,研究不同时间冷激处理对沂州木瓜可溶性固形物、VC、可滴定酸、硬度和失重率的影响。结果表明,0℃冰水混合物处理1h 可以明显减缓木瓜硬度的下降,减少果实VC 的分解和转化,抑制果实可滴定酸的下降,降低果实的失重率,从而延缓果实的成熟衰老。

Abstract:

Yizhou papaya was used to investigate the effect of cold shock treatment (CST) on soluble solids, vitamin C, titratable acids, hardness and weight loss rate. Results showed that the cold treatment using ice and water mixture for 1 hour obviously delayed the decrease of hardness of papaya, reduced the degradation of vitamin C, inhibited the decline of titratable acids and decreased the weight loss rate, which resulted in an effect on attenuating maturation and senescence for fruits.

Key words: cold shock treatment, Yizhou papaya, storage quality
