Abstract

Ber fruit is highly nutritious and is rich in bioactive compounds that are known to have several health benefits. Maintaining the quality of fruits during long term storage with polyphenolic extract in combination with edible coatings could be a novel way. Therefore, the present study is investigated to evaluate the potential application of pectin (1%) coating impregnated with karonda polyphenolic extract (KPPE) at concentrations of 0.5%, 1% & 1.5% on bioactive compounds, antioxidant capacity and quality of ber fruits during cold storage for 28 days. The results revealed that coating of ber fruits with pectin enriched in karonda polyphenolic extract markedly reduced spoilage, and maintained the firmness during the storage. The coating has resulted in higher retention of ascorbic acid, flavonoids, phenolics and antioxidant activity during storage. The treated fruits showed delayed ripening by slowing down the synthesis of carotenoids as compared to the control fruit. Further, the coating resulted in the lower activities of cell wall degrading enzymes, pectin methyl estarase (PME), and cellulase in the stored ber fruits. Moreover, the concentrations of karonda polyphenolic extract have worked in a dose-dependent manner in the coating system as pectin with 1.5% KPPE was found to be more effective in maintaining the quality and nutritional potential of ber fruit during storage.

果胶和卡隆达多酚复合食用涂料对浆果采后寿命的协同效应
浆果营养丰富,富含生物活性化合物,具有多种保健功效。利用多酚提取物结合可食用涂层来保持水果在长期储存过程中的质量,不失为一种新方法。因此,本研究评估了果胶(1%)浸渍卡龙达多酚提取物(KPPE)(浓度分别为 0.5%、1% & 1.5%)涂层在冷藏 28 天期间对浆果的生物活性化合物、抗氧化能力和质量的潜在应用。研究结果表明,用富含卡隆达多酚提取物的果胶涂覆浆果能明显减少腐烂变质,并在贮藏期间保持坚硬。涂覆后,抗坏血酸、类黄酮、酚类物质和抗氧化活性在贮藏期间的保留率更高。与对照水果相比,处理过的水果通过减缓类胡萝卜素的合成而延迟了成熟。此外,涂层还降低了贮藏浆果中细胞壁降解酶、果胶甲基酯酶(PME)和纤维素酶的活性。此外,在包衣系统中,卡隆达多酚提取物的浓度以剂量依赖的方式起作用,因为含有 1.5% KPPE 的果胶被发现在贮藏期间能更有效地保持浆果的质量和营养潜力。

期刊介绍: Erwerbs-Obstbau ist als internationales Fachorgan die führende Zeitschrift für Wissenschaftler, Berater und Praktiker im Erwerbsobstbau. Neben den wirtschaftlich führenden Obstarten widmet sich die Zeitschrift auch den Wildobstarten bzw. neuen Obstarten und deren zukünftige Bedeutung für die Ernährung des Menschen. Originalarbeiten mit zahlreichen Abbildungen, Übersichten und Tabellen stellen anwendungsbezogen den neuesten Kenntnisstand dar und schlagen eine Brücke zwischen Wissenschaft und Praxis. Die nach einem Begutachtungsprozeß zur Publikation angenommenen Originalarbeiten erscheinen in deutscher und englischer Sprache mit deutschem und englischem Titel. Review-Artikel, Buchbesprechungen und aktuelle Fachinformationen runden das Angebot ab.
