چکیده مقاله :
مقدمه: افزایش ماندگاری، کنترل عوامل فساد و حفظ کیفیت جوانه گندم در طول مدت نگهداری با استفاده از یک بسته بندی مناسب امکان پذیر می باشد. یکی از فناوری های نوینکه امروزه برای نگهداری مواد غذایی مورد توجه محققین قرار گرفته است، استفاده از بسته بندی هایی برپایه نانو ذرات می باشد.مواد و روشها: در این تحقیق، ابتدا فیلمهای بر پایه نانو ذرات نقره تهیه شد و برخی ویژگی های فیلم های شامل نفوذ بخار آب، ضخامت و مورفولوژی سطحی آنها با استفاده از میکروسکوپ الکترونی مورد ارزیابی قرار گرفت. ماندگاری، برخی ویژگی های شیمیایی و میکروبی جوانه گندم در بسته های پلی اتیلنی اصلاح شده با نانو ذرات نقره بررسی گردید. جوانه های گندم درسه نوع پوشش پلی اتیلنی حاوی 3 و 5 درصد وزنی نانو ذرات نقره و همچنین بسته بندی پلی اتیلن خالص (نمونه شاهد) بسته بندی شد، و در 3 دمای مختلف (2، 4، 6) درجه سانتی گراد و در 3 زمان نگهداری مختلف (0، 5، 10) روز مورد ارزیابی قرار گرفت.یافتهها: نتایج نشان داد که دما ، زمان نگهداری و غلظت نانو نقره در بسته بندی پلی اتیلن تأثیر معنی داری بر رطوبت ،pH و فعالیت آنزیمی جوانه گندم دارد. همچنین ماندگاری جوانه گندم با افزایش غلظت نانو نقره از 3% به 5% و با کاهش دما از 6 درجه سانتی گراد به 2 درجه سانتیگراد تا ده روز افزایش می یابد. بسته های دارای نانو ذرات توانستند به طور معنی داری (P<0.05) رشد کپک را در جوانه گندم کاهش دهند.نتیجه‌گیری: بر اساس نتایج بدست آمده استفاده از فیلمهای برپایه نانوذرات نقره باعث افزایش ماندگاری جوانه گندم می شود. جوانه گندم در بسته بندی با 5٪ نانوذرات نقره در دمای دو درجه سانتی گراد بیشترین ماندگاری را داشت و به عنوان نمونه منتخب تعیین شد.
Introduction: It is possible to increase the shelf life and maintain the quality of wheat germ during storage by using suitable packaging. One of the new technologies considered by researchers is the use of packaging based on nanoparticles.Materials and Methods: In this study, wheat germs were packaged in polyethylene packages containing silver nanoparticles, and the effect of the packaging on the quality characteristics and shelf life of wheat germ were determined. In this research work, at determining the most optimal conditions for the packaging of wheat germ, the effects of weight percent (wt%) of nanosilver (0, 3, and 5%), time of storage (0, 5, and 10 days), and three different temperatures (2, 4, and 6 0C) on the shelf life of wheat germ have been studied.Results: The results showed that temperature, storage time, and concentration of nanosilver in polyethylene packaging had significant effects on moisture, pH, and enzyme activity of wheat germ. Experimental data indicated that the storage time of wheat germ increased by increasing the concentration of nanosilver from 3% to 5% and by decreasing temperature from 6 ° C to 2 ° C for ten days. Nanoparticle packages were significantly (P <0.05) able to reduce mold growth in wheat germ.Conclusion: Based on the results, it might be concluded that the application of films based on silver nanoparticles increases the shelf life of wheat germ. Wheat germ had the highest shelf life in packaging with 5% silver nanoparticles at 2 ° C and was selected as the selected sample.
