中文摘要:
      本文研究了Na5(NH4)16[Mo57Mn6(NO)6O174(OH)3(H2O)24]·44H2O(以下记为Mo57Mn6)处理对鲜切苹果的保鲜效果,在贮藏期间对苹果的失重率、褐变度、丙二醛生成量、过氧化物酶活性和多酚氧化酶活性等5项指标进行连续测定,结果表明:Mo57Mn6能在1周内有效保水、保色,并降低丙二醛的生成量,抑制多酚氧化酶的活性,且在贮藏后期能激活过氧化物酶的活性。结论:Mo57Mn6能够延长苹果的货架期。
英文摘要:
      This paper investigated the fresh-maintaining effects of Na5(NH4)16[Mo57Mn6(NO)6O174(OH)3(H2O)24]·44H2O (abbreviated Mo57Mn6) processing on fresh-cut apples, and continuously measured five indexes, including weight loss ratio, browning degree, malonaldehyde yield, peroxidase (POD) activity and polyphenol oxidase (PPO) activity. The results indicate the processing of Mo57Mn6 can hold water and keep color effectively, and can decrease the yield of malondialdehyde and inhibit the activity of polyphenol oxidase within a week. It also can activate the activity of peroxidase in the late storage. In conclusion, Mo57Mn6 can effectively extend the shelf life of apples. The research results can provide some experimental basis for the development of novel fresh-keeping agents of fruits and vegetables, and enlarge the application scope of polyoxometalates.
