Determination of Some Quality Properties of Blueberry Fruit Coated with Edible Coating (Vaccinium Arctostaphylos)

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.
