چکیده

در پژوهش حاضر تاثیر تابش فرابنفش در محدوده UV-C با طول موج 254 نانومتر در بهبود ماندگاری دانه­های انار ارزیابی گردید. برای این منظور ابتدا سامانه پیوسته پرتودهی فرابنفش ساخته شد و دانه‌های انار با دو دُز 3/6 و 4/8 کیلوژول بر مترمربع پرتودهی شدند. نتایج نشان داد که اثرات ساده و متقابل تابش فرابنفش، نوع ظرف و مدت زمان نگهداری بر افت وزن و شاخص­های رنگ معنی­دار شد و به طور متوسط باعث 27% کاهش در افت وزن، %7 افزایش در شاخص L*، % 7/6 کاهش در مقدار a* و %10 افزایش در مقدار b* نمونه­های کنترل نسبت به شاهد گردید. با افزایش دُز پرتودهی شمارش کل باکتری­ها و قارچ­ها به صورت معنی­دار و به میزان 65/1 چرخه لگاریتمی در هر گرم کاهش یافت. به علاوه، پرتودهی تاثیر معنی­داری بر ویژگی­های حسی مورد مطالعه (رنگ، طعم و مزه، عطر و بو، بافت و پذیرش کلی) داشت. به­طور کلی، بر مبنای نتایج ارزیابی حسی، شاخص­های رنگ و رشد میکروبی، دُز تابش 3/6  کیلوژول بر مترمربع برای افزایش ماندگاری دانه­های انار قرار گرفته در بسته‌بندی بدون منفذ پیشنهاد می­گردد.

چکیده [English]

In this present study, the effect of ultraviolet radiation in the UV-C range with the wavelength of 254 nm on the increasing shelf-life of pomegranate arils was evaluated. For this purpose, at the first, a continuous ultraviolet irradiation system was constructed and pomegranate arils were irradiated with two doses of 6.3 and 8.4 kJ/m2. The results showed that the simple and interactive effects of UV irradiation, container type and storage time on the weight loss and color indices were significant and on average caused 27% decrease in weight loss, 7% increase in the L* index, 6.7% decrease in the a* value and 10% increase in the b* value of the control samples. With increasing irradiation dose, the total bacterial and fungal count were significantly reduced by 1.65 Log cfu g-1. Furthermore, the irradiation had a significant effect on the studied sensory properties (aroma, color, texture, and overall acceptance). Generally, based on the results of sensory evaluation, color indices and microbial growth, irradiation dose of 6.3 kJ/m2 is recommended to increase pomegranate arils shelf-life in non-porous packaging.
