Sofralık Üzümlerde Hasat Sonrası Hastalıklara Karşı Antimikrobiyal Modifiye Atmosfer Ambalajlarının Kullanımı

Amaç: Bu çalışmada, 2017 yılında Manisa Alaşehir bölgesinde üretilen Sultani ve Red Globe çeşidi üzümler, 5 farklı MAP ve bu paketlerin SO2 ve AM pad’ler ile kombinasyonları 3oC’de ve %90-95 bağıl nemde etkileri incelenmiştir. Materyal ve Metot: Hasat edilen ürünler ürünler, 5 farklı modifiye atmosfer paketi ile depolanıp ve depolanmadan önce ürünlerin mikrobiyolojik analizleri yapılmıştır. Depolama sonunda kilo kaybı, kilogram başına çürük dane sayısı, kalite kriterleri ve mikrobiyolojik analiz sonuçları belirlenmiştir. Ek olarak depolama süresinin sonunda, kilogram ürün başına çürümüş dane sayısı belirlenip, çalışmada kullanılan polietilen paketlerin ve antimikrobiyal paketlerin çürüme oranları karşılaştırılmıştır. Ayrıca ürünlerin kalite kriterleri olan salkım iskeleti kararması, meyve renginin değişimi, tat değişimleri belirlenmiştir. Bulgular: Araştırmada kullanılan antimikrobiyal paketin ve bu paketin ¼ SO2jeneratörü ve antimikrobiyal filmlerle kombinasyonunun kalite kriterlerini farklı şekilde etkilediği, ancak genellikle ürün çürümelerini azalttığı görülmüştür. Sonuç: Araştırma sonucunda klasik polietilen SO2jeneratör kombinasyonları yerine antimikrobiyal etkiye sahip ambalajların kullanılabileceği belirlenmiştir.

Use of Antimicrobial Modified Atmosphere Packages Against Postharvest Diseases in Table Grapes

Objective: In this study, Sultana and Red Globe grape varieties which producedin Alaşehir region of Manisa were examined in order to determine the effects of 5differents MAPs and these MAPs combinations with SO2 pad and AM pad in 3oC and%90-95 humidity.Material and Methods: The products were stored with 5 different modified atmospherepackings. Before storage, microbiological analysis of the products was carried out. Atthe end of the storage time, weight loss, decayed berries per kg, quality criteria andmicrobiological analysis results were determined. In addition, at the end of the storagetime, decayed berries per kg of the products were determined and compared with thedecay rates of the polyethylene packages and antimicrobial packages which were alsoused in the study. Also, the quality criteria of the products, rachis browning, berriescolor changing, taste changing were determined.Results: The antimicrobial package used in the research and the combination of thispackage with ¼ SO2 generator and antimicrobial films have been found to affect thequality criteria assessed in the study at different levels but generally reduce productdecay.Conclusion: As a conclusion of the research, it was determined that packages withantimicrobial capability could be used instead of classic polyethylene SO2 generatorcombinations.
