- 摘要:
- 以“红富士”苹果为试材，以蒸馏水为对照，分别采用银杏叶提取液、外种皮提取液、稀释3倍的银杏叶提取液、稀释3倍的外种皮提取液进行浸泡处理，处理后贮藏于8 ℃条件下测定相关指标，以探究银杏外种皮及银杏叶提取液对果蔬保鲜的影响。结果表明：银杏外种皮和银杏叶提取液可以在一定程度上延缓鲜切苹果失重率的上升，减缓鲜切苹果软化，以及减缓鲜切苹果中可滴定酸、可溶性固形物、花青素、总酚以及类黄酮含量的下降。其中稀释3倍的银杏叶提取液处理的保鲜效果最佳。
- Abstract:
- Ginkgo biloba L.was used as test material，the effect of the extracts of exotesta and leaves of Ginkgo biloba L.on fruit and vegetable fresh-keeping were investigated.‘Red Fuji’ apple were sorted at 8 ℃ after dipping in the extracts of exotesta(WY)，the extracts of leaves(YY)，the extracts of exotesta were diluted 3 times(W3)，the extracts of leaves were diluted 3 times(Y3) and distilled water for 5 minutes.The indexes related with fresh-keeping of ‘Red Fuji’ apples were measured during the storage period.The results showed that the extracts of ginkgo leaves and exotesta could delay the loss-weight rate of fresh-cut apple in a certain extent，delay the softening of fresh-cut apple，and slow down the contents of titratable acid，soluble solids，anthocyanin，total phenolic and flavonoid of fresh-cut apple.Dipping in Y3 for 5 minutes was better than the others in fresh-keeping of fresh-cut apples.
