چکیده
هدف از این مطالعه استفاده از پوشش خوراکی ژل آلوئه‌ورا همراه با اسانس رازیانه به‌منظور افزایش ماندگاری و حفظ ویژگی‌های کیفی سیب بود. در این پژوهش به‌منظور بررسی تأثیر ژل آلوئه‌ورا (در غلظت 50 درصد) و اسانس رازیانه (سطوح صفر، 500 و 1000 پی‌پی‌ام) بر برخی خصوصیات کیفی و حسی سیب در دمای چهار درجه سانتی‌گراد طی چهار دوره انبارداری (1، 10، 20 و 30 روز) آزمایشی به‌صورت فاکتوریل در قالب طرح کاملاً تصادفی با سه تکرار انجام شد. در هر دوره انبارداری افت وزن، مواد جامد محلول کل، اسیدیته قابل تیتراسیون، ارزیابی حسی، رنگ و pH مورد بررسی قرار گرفت. نتایج نشان داد که بیشترین میزان افت وزن مربوط تیمار بدون پوشش و کمترین میزان افت وزن مربوط به تیمار پوشش آلوئه‌ورا 50 درصد +1000 پی‌پی‌ام اسانس رازیانه در روزهای 10، 20 و 30  بود (P<0.05). بیشترین میزان مواد جامد محلول کل و pH در تیمار بدون پوشش در روزهای 10، 20 و 30 مشاهده شد (P<0.05). کمترین میزان اسیدیته قابل تیتراسیون در تیمار بدون پوشش و پوشش آلوئه‌ورا در روزهای 10، 20 و 30 مشاهده شد (P<0.05). تمامی تیمارهای پوشش داده شده در مقایسه با تیمار شاهد شاخص طعم و شاخص زردی (a) بالاتری در طی روزهای مختلف انبارداری داشتند (P<0.05). یافته‌های این پژوهش نشان داد که ژل آلوئه‌ورا (غلظت 50 درصد) و اسانس رازیانه (غلظت 500 و 1000 پی‌پی‌ام) می‌توانند به عنوان پوشش خوراکی جهت افزایش ماندگاری و حفظ ویژگی‌های کیفی میوه سیب در دمای چهار درجه سانتی‌گراد مؤثر باشد.

چکیده English

The aim of this study was to use edible coating of Aloe vera gel (AVG) with fennel essential oil (FEO) to increase shelf life and maintain qualitative characteristics of apples. Therefore, the present study was performed to investigate the effect of Aloe vera gel (at a concentration of 50%) and different levels of fennel essential oil (0, 500, and 1000 ppm) on some qualitative and sensory characteristics of apples fruit during three storage period (1, 10, 20, and 30 days) was conducted as a factorial experiment in a randomized complete base design with 3 replications. In each storage period, weight loss percentage, total soluble solids (TSS), titratable acidity (TA), sensory evaluation, color, and pH were examined. The results showed that the highest weight loss was related to the control treatment (without Aloe vera gel and essential oil) and the lowest weight loss was related to the treatment with 50% AVG + 1000 ppm FEO on days 10, 20 and 30 (P<0.05). The highest TSS and pH were observed in the control treatment on days 10, 20 and 30 (P<0.05). The lowest TA was observed in the control and AVG coated treatments on days 10, 20 and 30 (P<0.05). All coated treatments had higher taste index and yellowness index (a) during different days of storage compared to the control treatment (P<0.05). The findings of this study showed that Aloe vera gel (50%) and fennel essential oil (500 and 1000 ppm) can be effective as edible coatings to increase shelf life and maintain qualitative characteristics of apple fruit at 4°C.
