摘要:

摘 要:以红富士苹果为原料,用不同浓度的生姜提取液对鲜切苹果进行浸泡处理,通过对贮藏期间生理品质指标及微生物动态变化的测定,研究了生姜提取液对鲜切红富士苹果的保鲜效果。结果表明:生姜提取物能显著延缓呼吸速率及乙烯释放量,降低失重率和可滴定酸的损失,有效抑制PPO活性及MDA的积累,减少微生物对鲜切苹果的侵染,较好地保持了鲜切红富士苹果的品质。结合感官品质模糊评价得出:0.1g?ml-1的生姜提取物保鲜效果最佳。

Abstract:

Abstract: The effect of ginger extract on preservation of fresh-cut ‘Red Fuji’ apple was researched under immersing process with different concentrations, and physiological-quality indexes and microbial dynamic change were determined during the storage period. The results showed that: the respiratory rate and ethylene release quantity were significantly delayed. The weightlessness rate and the loss of acid titration were significantly reduced. The PPO activity and the accumulation of MDA were effectively inhibited. Combined with sensory quality that fuzzy evaluation, the best preservation effect was the 0.1g?ml-1ginger extract.
