Measurements of firmness, titrable acid, pH, weight loss, total antioxidant capacity, total phenolic, anthocyanin, vitamin C, enzymes' activity including catalase, peroxidase, and polyphenol oxidase and decay were carried out at 0, 6, 12, 18, and 24 d of storage. All applied treatments caused a significant effect on measured parameters including weight loss, titratable acidity, decay percentage and firmness, maintenance of anthocyanin and vitamin C contents, total phenolic, and antioxidant capacity. However, grape skin extract and grape seed extract showed the best results.
