چکیده
ببسته­بندی با خاصیت ضد میکروبی یکی از مهم­ترین کاربردهای بسته­بندی فعال است. ﭘﮋوﻫﺶ حاضر با هدف ﺑﺮرﺳﻲ اﺛﺮ بسته­بندی فعال ضد میکروبی بر کیفیت پس از برداشت ﻣﻴﻮه ﺗﻮت ﻓﺮﻧﮕﻲ رﻗﻢ کامارزا اﻧﺠﺎم ﺷﺪ. آزﻣﺎﻳﺶ ﺑﻪﺻﻮرت ﻓﺎﻛﺘﻮرﻳﻞ در ﻗﺎﻟﺐ ﻃﺮح ﻛﺎﻣﻼً ﺗﺼﺎدﻓﻲ ﺑﺎ 4 نوع بسته­بندی میوه شامل شاهد بدون تلقیح قارچ، شاهد با تلقیح قارچ، و بسته­بندی شده با غلظت 12 و 24 میکرولیتر اسانس نعناع فلفلی در میلی­لیتر هوای بسته و زﻣﺎن آنالیز (0، 4، 8 و 12 روز) اﺟﺮا ﺷﺪ. در طی آزمایش صفات کیفی و بیوشیمیایی مورد بررسی قرار گرفت. ﻧﺘﺎﻳﺞ ﻧﺸﺎن داد ﻛﻪ ﺑﺎ اﻓﺰاﻳﺶ دوره نگهداری در همه میوه­های بسته­بندی شده ﺷﺎﺧﺺﻫﺎی درصد پوسیدگی، ﻛﺎﻫﺶ وزن، آﻧﺘﻮﺳﻴﺎﻧﻴﻦ ﻛﻞ، فنول و ﻓﻼوﻧﻮﺋﻴﺪ ﻛﻞ به طور معنی­داری اﻓﺰاﻳﺶ درﺣﺎﻟﻲ ﻛﻪ ﻣﻴﺰان ویتامین ث، و ﻇﺮﻓﻴﺖ آنتی اکسیدانی ﻛﺎﻫﺶ ﻳﺎﻓﺖ در میوه­ﻫﺎی بسته­بندی شده ﺑﺎ اسانس نعناع فلفلی ﺑﻪ ﻃﻮر ﻣﻌﻨﻲداری صفات کیفی بهبود یافت. جمعیت میکروبی طی دوره نگه­داری در تیمارهای شاهد افزایش و در بسته میوه حاوی اسانس نعناع فلفلی کاهش یافت. غلظت 24 میکرولیتر/میلی­لیتر اسانس نعناع فلفلی لود شده در فوم میکروسلولی نشاسته با رهایش آهسته توانست درصد پوسیدگی میوه و وﻳﮋﮔﻲﻫﺎی ﻛﻴﻔﻲ ﻣﻴﻮه ﺗﻮتﻓﺮﻧﮕﻲ را ﻃﻲ اﻧﺒﺎرداری ﺳﺮد حفظ نماید. با توجه به اینکه اسانس گیاه نعناع فلفلی بعلت وجود ترکیباتی غالب نظیر منتون و منتول در غلظت­های نسبتاٌ پایین روی رشد قارچ بویتریتیس بسیار موثر است، لذا استفاده از این اسانس بجای مواد نگهدارنده مصنوعی که اثرات سوء آن­ها مشخص شده است یک امر مفید و مؤثر به نظر می­رسد.

چکیده English

Antimicrobial packaging is one of the most important applications of active packaging. The purpose of this study was to investigate the effect of antimicrobial packaging on the quality of strawberry fruit cv. Camarosa The experiment was conducted as factorial in a completely randomized design with four types of fruit packaging control with no inoculation and inoculation of fungi, 12 and 24 μl of essential oil /ml air and the second factor was sampling time (harvest time, 4, 8 and 12 days). During the experiment, traits qualitative and biochemical properties were investigated. The results showed that with increasing storage time in all treatments, decay percentage, weight loss, total anthocyanin, total phenol and flavonoid increased, while the amount of vitamin C and antioxidant capacity decreased. The amount of vitamin C, flavonoids and antioxidant capacity in fruits treated with peppermint essential oil were significantly higher than those of the control group. The microbial populations during the storage period was decreased in the treatment of essential oils. Totally, It seems that The concentration of 24 μl / ml peppermint essential oil loaded with microselle foam with slow release could reduce the percentage of fruit decay and microbial populations and maintain the qualitative and biochemical properties of strawberry fruit during cold storage. Considering that the essential oil of peppermint is very effective on the growth of Botrytis cinerea due to the presence of dominant components such as menthol and menthol at relatively low concentrations, so using this essential oil instead of artificial preservatives, It looks like something useful and effective.
