ABSTRACT

An investigation was carried out to evaluate the influence of the post-harvest application of different ethylene inhibitors viz., 1-methylcylcopropene (1-MCP; 500, 1000 and 1500 ppb), methyl jasmonates (MeJA; 1, 2 and 3 mM) and salicylic acid (SA; 1, 2 and 3 mM) on health-promoting compounds such as total phenols, total antioxidants, flavonoids, protein, total free amino acids and sugars in cold-stored ‘Kinnow’ mandarin fruit. The fruit were stored at 6 ± 1°C and 90 ± 5% RH for 75 days. Fruit treated with MeJA (1 mM), 1-MCP (1500 ppb) and SA (2 mM) maintained significantly highest levels of total phenols, total antioxidants activity, flavonoids, protein, total free amino acids and sugars as compared with the control. In conclusion the post-harvest application of MeJA (1 mM), 1-MCP (1500 ppb) and SA (2 mM) can be used to maintain the highest levels of these bioactive compounds in cold-stored ‘Kinnow’ mandarin fruit for up to 60 days.

摘要

进行了一项研究,以评估收获后施用不同乙烯抑制剂的影响,即1-甲基环丙烯(1-MCP; 500、1000和1500 ppb),茉莉酸甲酯(MeJA; 1、2和3 mM)和水杨酸(SA; 1、2和3 mM)用于促进健康的化合物,例如冷藏的“ Kinnow”橘子水果中的总酚,总抗氧化剂,类黄酮,蛋白质,总游离氨基酸和糖。将果实在6±1°C和90±5%RH下保存75天。与对照相比,用MeJA(1 mM),1-MCP(1500 ppb)和SA(2 mM)处理的水果保持了最高水平的总酚,总抗氧化剂活性,类黄酮,蛋白质,总游离氨基酸和糖含量。总之,MeJA(1 mM)的收获后应用,
