چکیده
پوشش‌های خوراکی ضد میکروب حاوی اسانس‌های گیاهی دارای مزایای مختلفی هستند و در حال حاضر برای طراحی بسته‌بندی‌های زیست تخریب‌پذیر استفاده می‌شوند. در این پژوهش، اسانس دارچین در غلظت‌های صفر، 3/0، 6/0 و 9/0 درصد به محلول موسیلاژ دانه بالنگوی شهری به منظور تولید پوشش خوراکی زیست فعال اضافه گردید. نمونه‌های توت‌فرنگی با پوشش خوراکی پوشش یافتند و تغییرات فیزیکوشیمیایی، میکروبی و حسی آن­ها طی دوره نگهداری 10 روزه در دمای 4 درجه سانتی­گراد بررسی گردید. در مقایسه با نمونه کنترل، استفاده از پوشش خوراکی مبتنی بر موسیلاژ دانه بالنگوی شهری حاوی 9/0 درصد اسانس دارچین، بطور معنی‌داری از تغییرات pH، اسیدیته، میزان مواد جامد محلول (69/13 درصد در برابر 5/43 درصد افزایش)، بار میکروبی (log CFU/g 22/3 در برابر 98/3)، تجزیه بافت (74/6 در برابر 05/33 درصد) و ویژگی‌های حسی (رنگ، بو، بافت و پذیرش کلی) میوه توت‌فرنگی طی دوره نگهداری جلوگیری نمود. بنابراین پوشش خوراکی بر پایه موسیلاژ دانه بالنگوی شهری غنی شده با اسانس دارچین می‌تواند به‌عنوان یک بسته‌بندی فعال برای بهبود ویژگی‌های کیفی و ایمنی توت­فرنگی استفاده شود.

چکیده English

Antimicrobial edible coatings containing plant essential oils have various advantages and are currently being used to design biodegradable packaging. In this study, cinnamon essential oil was added at concentrations of 0, 0.3, 0.6 and 0.9% to the Shahri Balangu seed mucilage solution to produce a bioactive edible coating. Strawberry samples were coated with the edible coating and their physicochemical, microbial, and sensory changes were evaluated during a 10-day storage period at 4 °C. Compared to the control sample, the use of edible coating based on Shahri Balangu seed mucilage containing 0.9% of cinnamon essential oil, significantly inhibited the changes in pH, acidity, soluble solids (13.69% vs. 43.5% increase), microbial count (3.22 vs. 3.98 log CFU/g increase), hardness (6.74% vs. 33.05%), and sensory properties (color, odor, texture, and overall acceptance) of strawberry fruit during storage. Therefore, the edible coating based on Shahri Balangu seed mucilage containing cinnamon essential oil can be used as an active packaging to improve the quality and safety characteristics of various food products.
