چکیده

عمر کوتاه و حساسیت به سرمازدگی بزرگ‌ترین مشکل پس از برداشت رقم‌های خرمالو است. از جمله تیمارهای مؤثر در افزایش ماندگاری پس از برداشت میوه­ها استفاده از فناوری نانو است. در این پژوهش تأثیر به کارگیری ظرف‌های نانو سیلیکات، ظرف‌های پلی­اتیلن معمولی و بدون بسته­­بندی (شاهد) بر حفظ خواص کیفی میوۀ خرمالو رقم کرج در چهل روز انبارداری آن در دمای 1 درجۀ سلسیوس و رطوبت نسبی 95-90 درصد بررسی شد. در مدت­های 20 و 40 روز میوه­ها از انبار سرد خارج و پس از سه روز نگهداری در دمای معمولی به‌عنوان عمر قفسه­ای ویژگی­هایی همانند شاخص سرمازدگی، درصد کاهش وزن، سفتی بافت میوه، مواد جامد محلول­ کل، اسید قابل عیارسنجی (تیتراسیون)، میزان آسکوربیک اسید، محتوای تانن محلول، کاروتنوئید کل، فلاونوئید کل و فعالیت پاداکسندگی (آنتی­اکسیدانی) کل اندازه­گیری شد. نتایج نشان داد، بسته­بندی نانو در هر دو مدت انبارداری در مقایسه با ظرف‌های پلی‌اتیلن معمولی و شاهد موجب حفظ بهتر خواص کیفی، میزان آسکوربیک اسید، میزان تانن محلول، فلاونوئید کل و فعالیت پاداکسندگی میوه در دورۀ انبارداری شد. همچنین میوه‌های خرمالوی بسته‌بندی‌شده با نانو سیلیکات کمترین شاخص سرمازدگی (01/0 درصد)، کاهش وزن (32/1 درصد) و بیشترین میزان سفتی (33/5 نیوتن بر سانتی­مترمربع) را داشتند. بنابراین استفاده از ظرف‌های حاوی نانو ذرات در افزایش ماندگاری پس از برداشت و حفظ کیفیت میوۀ خرمالو مؤثرتر بوده است.

چکیده [English]

Short postharvest life and susceptibility to chilling are the most important problems of persimmon fruit cultivars. Use of nanotechnology is one of the most effective ways to extend storage life of fruits. In this study, effect of different packaging material including nano-silicate, polyethylene and control (without packaging) on quality and antioxidant properties of persimmon fruits cv. Karaj was investigated during 40 days of postharvest storage at 1 ºC and 90-95% relative humidity. The fruits were removed after 20 and 40 days of cold storage and subsequently held at ambient temperature for three days (shelf life), and were analyzed for chilling injury index, weight loss, flesh firmness, total soluble solids (TSS), titratable acidity (TA), ascorbic acid, soluble tannin, total flavonoids, total carotenoid contents and total antioxidant activity. The results showed that nano-packaging maintained quality attributes of ascorbic acid, soluble tannin, total flavonoids, total carotenoid contents and total antioxidant activity for longer period than polyethylene packaging and controls. Also, nano- packaged persimmon fruits had the least chilling index (0.01%), weight loss (1.32%) and the most flesh fruit firmness (5.33N/cm2). Therefore use of nano-packaging is beneficial for quality maintaining and postharvest life of persimmon fruit during storage.
