| چکیده | ||
| در این پژوهش، اثر پوشش پلاستیکی آغشته به نانوذرات تیتانیومدیاکسید بر کیفیت پس از برداشت ارقام میوهی سفید بی‌دانه، قزل اوزوم و ریش‌بابا در طی نگهداری در سردخانه بررسی شد. برای این منظور خوشه‌های انگور سالم، یکنواخت و عاری از هرگونه آسیب فیزیکی و پوسیدگی میکروبی با استفاده از لفاف‌های پلی‌اتیلنی آغشته به نانوذرات تیتانیومدیاکسید بسته‌بندی و به مدت 80 روز در سردخانه با دمای 1±0 درجه‌ی سانتی‌گراد و رطوبت نسبی 5±90 درصد نگهداری شد. ویژگیهای مواد جامد محلول کل، اسیدیته قابل تیتراسیون، ضریب رسیدگی، pH و محتوای فنول کل حبه‌های انگور در فواصل زمانی 20 روزه اندازه‌گیری شد. آنالیز آماری نتایج نشان داد که تیمار نانوذرات تیتانیومدیاکسید تاثیر معنی‌داری را در کاهش اسیدیته قابل تیتراسیون، pH، محتوای فنول کل و ضریب رسیدگی نسبت به نمونه‌های کنترل داشتند. به طوری که نمونه‌های تیمارشده با نانوذرات تیتانیومدیاکسید میزان مواد جامد محلول و اسیدیته قابل تیتراسیون بالاتری را از خود نشان دادند. نتایج پژوهش حاضر نشان داد هر سه رقم انگور بسته‌بندی شده با لفاف‌های پلی‌اتیلنی آغشته به نانو ذرات تیتانیومدیاکسید نسبت به نمونه‌های شاهد کیفیت بالاتری در پایان دوره‌ی انبارداری داشتند. | ||

| In this research, the effect of plastic coating impregnated with titanium dioxide nanoparticles on the post-harvest quality of seedless white fruit cultivars, Qezel Ozum and RishBaba during cold storage was investigated. For this purpose, healthy, uniform and free from any physical damage and microbial decay grape bunches were packed using polyethylene wrappers impregnated with titanium dioxide nanoparticles and stored for 80 days in a cold store with a temperature of 0±1°C and a relative humidity of 90±5%. The characteristics of total soluble solids, titratable acidity, ripening factor, pH and total phenolic content of grapes were measured at 20-day intervals. The statistical analysis of the results showed that the treatment of titanium dioxide nanoparticles had a significant effect in reducing the titratable acidity, pH, total phenol content and ripening coefficient compared to the control samples. The samples treated with titanium dioxide nanoparticles showed higher soluble solids and titratable acidity. The results showed that all three grape cultivars packed with polyethylene wrappers impregnated with titanium dioxide nanoparticles had higher quality than the control samples at the end of the storage period. | ||
