基于灰色关联度法解析VB6外源处理对上海青采后品质的影响
Effect of Exogenous VB6 Treatment on the Postharvest Quality of Pakchoi Based on Grey Relational Analysis
摘要
Abstract
This study investigated the effects of postharvest immersion treatment with different concentrations of VB6 on the quality of pakchoi(Brassica rapa subsp.chinensis)stored at(15±1)℃.A comprehensive evaluation was conducted using grey relational analysis.The results demonstrated that 200 mg/L VB6 treatment resulted in the lowest yellowing index and significantly delayed the decline in chlorophyll content.After 8 days of storage,the total chlorophyll content in this treatment group was 44.9%higher than that in the control group.This treatment effectively maintained the levels of antioxidants including ascorbic acid and total phenols(which were increased by 21.6% and 14.9%compared to the untreated control group,respectively),while significantly inhibiting the accumulation of malondialdehyde(MDA)and nitrite(which were decreased by 36.4% and 24.3%,respectively).Furthermore,it enhanced the activities of catalase(CAT),peroxidase(POD),and superoxide dismutase(SOD),and increased the 1,1-diphenyl-2-picrylhydrazyl(DPPH)radical scavenging activity and total reducing power.Grey relational analysis revealed that the 200 mg/L VB6 treatment achieved the highest comprehensive score(0.776).It is confirmed that 200 mg/L VB6 can delay the postharvest senescence of pakchoi through multiple physiological pathways,which provides theoretical support for the development of novel preservation technologies.关键词
