Abstract

Bu çalışmanın amacı, farklı dozdaki UV-C ışın uygulamalarının Giant Erik çeşidinin meyve kalitesi ve soğukta muhafaza süresi üzerine etkinliğinin belirlenmesidir. Meyvelere 50 ve 100 cm mesafeden 5, 10 ve 20 dakika süre ile ışın uygulaması yapıldıktan sonra 750 g’lık kaplar içerisinde polietilen torbalar ile ambalajlanmıştır. Tüm paketler 0-10C sıcaklık ve %90±5 nispi neme sahip depoda 5 hafta süre ile muhafaza edilmiştir. Soğukta muhafaza süresince haftalık olarak meyve örneklerinde ağırlık kaybı, meyve sertliği, suda çözünür kuru madde miktarı, titre edilebilir asitlik miktarı, suda çözünür kuru madde miktarı / titre edilebilir asitlik miktarı oranı, pH ve duyusal tat ve görünüş analiz ölçümleri yapılmıştır. Muhafaza süresince uygulamalara göre değişmekle birlikte genel olarak ağırlık kayıpları ve suda çözünür kuru madde miktarı artmış, meyve eti sertliği ve titre edilebilir asitlik miktarı ise azalmıştır. Araştırmada, 35. gün sonunda kalite kayıpları en çok 100 cm 5 dak ve 20 dak UV-C dozu ile kontrol grubunda görülmüş, en iyi sonuçlar ise 50 cm 5 dak ve 10 dak UV-C dozunda belirlenmiştir

Effects of Postharvest UV-C Treatments on Quality and Cold Storage of cv. Giant Plum

Abstract

The aim of this study is to determine effectiveness of different UV-C treatments on fruit quality and cold storage period of cv. Giant plum. After fruits were treated UV-C from 50 and 100 cm distance for 5, 10 and 20 min, they were placed in container 750 g and packed with polyethylene bag. All packages were stored at 0-10C and 90±5 % relative humidity for 5 weeks. During the storage period, weight loss, fruit firmness, soluble solids content, titretable acidity, soluble solids content / titretable acidity , fruit juice pH and sensorial taste and appearance analyze measurements in fruit samples were performed at 1 week interval. Although it changed according to treatments, weight loss and soluble solids content generally increased; fruit firmness and titretable acidity decreased in the course of storage period. In the research, the highest quality losses were observed in UV-C treatment from 100 cm distance for 5, 20 min and control at the end of 35 days, the best results were obtained from UV-C treatment from 50 cm for 5 and 10 min
