Abstract

Alkyl polyglucosides (APGs) and polyethylene glycol glycosides (PEGG) were applied as coatings on fresh pineapple to extend their postharvest shelf-life and to prevent Black Heart (BH). The pineapples were coated with solutions of APGs and PEGG, and the tissue firmness, total soluble solids (TSS), grade of freshness, incidence and grade of BH were measured. The APGs and PEGG were obviously able to reduce the decay incidence, firmness and flavor loss as well as retard color change and ripening rate of pineapples during storage. C12/14-APGs could not only improve quality and shelf-life characteristics, but also markedly reduce incidence of BH. The combination of APGs with PEGG showed the obvious synergism for preventing BH.

Kurzfassung

Frische Ananas wurden mit Coatings aus Alkylpolyglucosiden (APG) und Polyethylenglykolglucosiden (PEGG) versehen, um nach der Ernte ihre Haltbarkeit zu verlängern und die Entstehung der Black Heart-Krankheit (BH) zu verhindern. Die Ananas wurden mit Lösungen aus APG und PEGG überzogen und die Gewebefestigkeit, der lösliche Gesamtanteil (TSS), der Frischegrad, das Auftreten und der Grad der BH der gecoateten Ananas bestimmt. APGs und PEGGs können offensichtlich den Fäulnisbefall, die Festigkeit und den Aromaverlust reduzieren. Weiterhin verzögern sie die Farbveränderung und verlangsamen die Reifungsgeschwindigkeit während der Lagerung. C12/14-APGs können nicht nur die Qualität und die Haltbarkeit verbessern, sondern auch den Befall mit BH merklich reduzieren. Mischungen aus APGs mit PEGGs liefern eine deutliche synergistische Wirkung bei der Vorbeugung vor BH.
