Guava is an important tropical and subtropical climacteric fruit rich in vitamin C. At ambient conditions, the fruit cannot be stored for a long period due to fast ripening, abrupt softening and fungal growth. The aim of the present study was to investigate the influence of postharvest sodium nitroprusside (SNP) treatment, a nitric oxide donor, on senescence and physicochemical quality of guava fruit. Mature-green fruits were given immersion treatment of sodium nitroprusside (0.5, 1.0, and 1.5 mM) for 5 min while, fruits under control were dipped in distilled water for the same duration. After the treatment, fruits were stored at ambient condition (20 ± 3 °C). Among the treatments, the best result with minimum weight loss (16.31%) and decay loss (22.22%) after 12 days of storage was noted in 1.0 mM SNP-treated fruits. Malondialdehyde content of fruits under this treatment also showed minimum increase of 5.3-fold indicating delayed senescence, as compared to control and other SNP-treated fruits. Fruits under this treatment exhibited delayed ripening, resulting minimum loss (53.23%) of chlorophyll, and slower increase in carotenoid pigments. Prestorage treatment of guava with SNP (1.0 mM) presented minimum loss of total soluble solids and acidity as compared to control fruits. The loss in ascorbic acid (21.30%), phenols (22.25%), flavonoids (26.14%), antioxidant capacity (25.61%), and radical scavenging activity (34.21%) was minimum in guava fruits treated with 1.0 mM SNP. The study indicated that storage life of guava at ambient condition can be prolonged by postharvest immersion treatment of 1.0 mM SNP.

一氧化氮在番石榴果实采后保质上的应用

番石榴是一种重要的热带和亚热带的更年期水果,富含维生素C。在环境条件下,该水果由于快速成熟,突然软化和真菌生长而无法长期保存。本研究的目的是调查收获后一氧化氮供体硝普钠(SNP)处理对番石榴果实衰老和理化品质的影响。对绿色成熟的水果进行硝普钠(0.5、1.0和1.5 mM)浸泡处理5分钟,同时将受控制的水果在蒸馏水中浸泡相同的时间。处理后,将水果储存在环境条件下(20±3°C)。在这些处理中,在1.0 mM SNP处理的果实中,在保存12天后具有最小的重量损失(16.31%)和衰变损失(22.22%)的最佳结果。与对照和其他SNP处理的水果相比,在这种处理下水果的丙二醛含量也显示出最小的5.3倍增加,表明衰老延迟。经过这种处理的水果显示出延迟的成熟,导致叶绿素的损失最小(53.23%),并且类胡萝卜素色素的增加较慢。与对照水果相比,用SNP(1.0 mM)进行番石榴的储藏前处理可降低总可溶性固形物和酸度的损失。在用1.0 mM SNP处理的番石榴果实中,抗坏血酸(21.30%),酚(22.25%),类黄酮(26.14%),抗氧化能力(25.61%)和自由基清除活性(34.21%)的损失最小。该研究表明,在收获后浸泡处理1.0 mM SNP可以延长番石榴在环境条件下的储存寿命。与对照和其他SNP处理的果实相比,其3倍表明延迟了衰老。经过这种处理的水果显示出延迟的成熟,导致叶绿素的损失最小(53.23%),并且类胡萝卜素色素的增加较慢。与对照水果相比,用SNP(1.0 mM)进行番石榴的储藏前处理可降低总可溶性固形物和酸度的损失。在用1.0 mM SNP处理的番石榴果实中,抗坏血酸(21.30%),酚(22.25%),类黄酮(26.14%),抗氧化能力(25.61%)和自由基清除活性(34.21%)的损失最小。该研究表明,在收获后浸泡处理1.0 mM SNP可以延长番石榴在环境条件下的储存寿命。与对照和其他SNP处理的果实相比,其3倍表明延迟了衰老。经过这种处理的水果显示出延迟的成熟,导致叶绿素的损失最小(53.23%),并且类胡萝卜素色素的增加较慢。与对照水果相比,用SNP(1.0 mM)进行番石榴的储藏前处理可降低总可溶性固形物和酸度的损失。在用1.0 mM SNP处理的番石榴果实中,抗坏血酸(21.30%),酚(22.25%),类黄酮(26.14%),抗氧化能力(25.61%)和自由基清除活性(34.21%)的损失最小。研究表明,通过在采后浸泡1.0 mM SNP可以延长番石榴在环境条件下的储存寿命。导致叶绿素损失最小(53.23%),并且类胡萝卜素色素的增加较慢。与对照水果相比,用SNP(1.0 mM)进行番石榴的储藏前处理可降低总可溶性固形物和酸度的损失。在用1.0 mM SNP处理的番石榴果实中,抗坏血酸(21.30%),酚(22.25%),类黄酮(26.14%),抗氧化能力(25.61%)和自由基清除活性(34.21%)的损失最小。该研究表明,在收获后浸泡处理1.0 mM SNP可以延长番石榴在环境条件下的储存寿命。导致叶绿素损失最小(53.23%),并且类胡萝卜素色素的增加较慢。与对照水果相比,用SNP(1.0 mM)进行番石榴的储藏前处理可降低总可溶性固形物和酸度的损失。在用1.0 mM SNP处理的番石榴果实中,抗坏血酸(21.30%),酚(22.25%),类黄酮(26.14%),抗氧化能力(25.61%)和自由基清除活性(34.21%)的损失最小。该研究表明,在收获后浸泡处理1.0 mM SNP可以延长番石榴在环境条件下的储存寿命。用1.0 mM SNP处理的番石榴果实中的类黄酮(26.14%),抗氧化能力(25.61%)和自由基清除活性(34.21%)最低。该研究表明,在收获后浸泡处理1.0 mM SNP可以延长番石榴在环境条件下的储存寿命。用1.0 mM SNP处理的番石榴果实中的类黄酮(26.14%),抗氧化能力(25.61%)和自由基清除活性(34.21%)最低。该研究表明,在收获后浸泡处理1.0 mM SNP可以延长番石榴在环境条件下的储存寿命。
