Farklı Kurutma İşlemlerinin Nar Pres Atıklarının Biyoaktif Bileşenleri ve Antidiyabetik Özellikleri Üzerine Etkisi
Today, with the understanding of the favorable effects of fruit consumption on health, the consumption of pomegranate has increased gradually and solution methods were sought in order to evaluate the peel and seed parts that emerge after the fruit is sorted. In this study, the effects of different drying process (microwave, drying oven, and freeze-drying) and different extraction solvents (ethanol and methanol) on the bioactive components, antioxidant and antidiabetic activities of pomegranate press wastes were investigated. While the highest TPC was in freeze-dried methanolic extracts (5758.70 mg GAE 100 g-1), the highest TFC and MA contents were determined in microwave-dried ethanolic extracts with values of 1068.75 mg QE 100 g-1 dw and 215.44 mg cyn-3-glu 100 g-1, respectively. The highest DPPH antioxidant activity value was determined in freeze-dried ethanolic extracts with a value of 99.14%, and the highest ABTS value was determined in freeze-dried methanolic extracts with a value of 18.20 mmol Trolox g-1. α-amylase and α-glucosidase inhibition values of the samples range from 8.87 to 28.56 mg L-1 and 9.57 to 29.88 mg L-1, respectively. All samples had higher α-glucosidase inhibitory activity compared to acarbose. The results showed that pomegranate press waste, which is thought to have no use in the food industry, is a potential resource that can be used in the pharmacology and cosmetics industries as well as its use as a food supplement, thanks to its high antioxidant and antidiabetic properties.
