Abstract

In this study, blueberry fruit, which is consumed joyfully, was coated with edible coating material ( SemperfreshTM) and stored for 15 days at 4 °C. Antioxidant properties and some physical properties were determined after harvest 5 with days intervals (0, 5th, 10th, 15th days). In uncoated fresh fruits, the amount of dry matter soluble in water was determined as 13.22%, pH 3.41, titratable acidity 1.01%, reducing sugar 8.54g/100g, saccharose 0.17g/100g, total sugar 8.72g /100g, vitamin C 20.37mg/100g, L value 27.09, vitamin A value 0.18, vitamin B value 0.60, total phenolic content 2398.65 mg gallic acid/100g dry weight, DPHH radical scavenging activity (IC50 value) 0.24 and, ABTS radical scavenging activity (IC50 value) 7.61.Coating with SemperfreshTM was statistically significantly effective over the identified parameters in blueberry fruit (P< 0.01). When all parameters were examined in the study, it was seen that blueberry fruit lost less weight as a result of 15-day storage at 4°C when coated with SemperfreshTM. The amount of ascorbic acid could be determined up until the 10th day.
 
Bu çalışmada sevilerek tüketilen ayı üzümü meyvesi, yenilebilir kaplama malzemesi ile (SemperfreshTM) kaplanarak 4 °C’ de 15 gün depolanmıştır. Hasattan sonra 5 gün aralıklarla (0., 5., 10., 15. gün) antioksidan özellikleri ve bazı fiziksel özellikleri belirlenmiştir. Kaplanmamış taze meyvelerde suda çözünür kuru madde miktarı % 13,22, pH 3.41, titrasyon asitliği %1.01, indirgen şeker 8.54g/100g, sakaroz 0.17 g/100g, toplam şeker 8.72 g/100g, C vitamini 20.37 mg/100g, L değeri 27.09, a değeri 0.18, b değeri 0.60, toplam fenolik madde 2398.65 mg gallik asit/100g kuru ağırlık, DPHH radikal giderme aktivitesi (IC50 değeri) 0.24, ABTS radikal giderme aktivitesi (IC50 değeri) 7.61 olarak belirlenmiştir. SemperfreshTM’le kaplama ayı üzümü meyvesinde belirlenen parametreler üzerine istatistiki olarak önemli derecede etkili olmuştur (P< 0.01). Araştırmada bütün parametreler incelendiğinde ayı üzümü meyvesinin 4°C’de 15 günlük depolama sonucunda SemperfreshTM’le kaplandığında ağırlık kaybının daha az olduğu görülmüştür. Askorbik asit miktarı ise 10. güne kadar belirlenebilmiştir.
