摘要: 将刚采摘的草莓浸入不同浓度的植酸和山梨酸钾溶液中30s,然后在常温条件下保存,通过对草莓进行糖分和酸度测定,研究植酸对草莓储藏稳定性的影响。结果表明:浓度为0.05%~0.15%植酸用于草莓保鲜,可以延缓果实中维生素的降解,保持果实中的还原糖和总酸含量,在常温条件下可以保鲜一周,明显延长草莓贮存期。

Abstract:  Fresh strawberry fruits were dipped in different concentrations of phytic acid solution or potassium sorbate solution for 30 s and then stored under normal temperature condition in order to investigate the storage stability of strawberry through the determination of sugar content and acidity. The results showed that the preservation by 0.05% to 0.15% phytic acid can slow down the degradation of vitamin and keep reducing sugar and total acid contents. The storage period of strawberry is extended obviously by 7-day preservation of phytic acid at the normal temperature.
