Özet

Pomegranate is one of the most popular fruits worldwide, and it is important to maintain the overall quality and bioaccessibility of freshly squeezed pomegranate juices (PJS). The adverse effects of heat treatment on sensory properties and phytochemicals encourage the use of non-thermal processes in the juice industry. Hereby, the effects of high-pressure homogenization (HPH) (50, 100, and 150 MPa) on the physicochemical properties, antimicrobial activity, in vitro bioaccessibility, and antioxidant capacity of freshly-squeezed PJS from different genotypes were investigated. Instrumental color values (L*, a*, and b*) of PJS generally decreased, while pH and a(w) values increased with HPH processing (p < 0.05). The antimicrobial activity of PJS was not significantly affected by HPH processing (p > 0.05). Sar & imath;cakaya-1 had higher bioactive constituent content and antioxidant capacity (DPPH-ARA, ABTS-ARA, and FRAP) than other genotypes (p < 0.05). Total phenolic content (TPC) and antioxidant capacity of PJS were increased by HPH treatment, whereas total anthocyanin content (TAC) and ascorbic acid content (AAC) were decreased (p < 0.05). Accordingly, HPH treatment enhanced the release of phenolics and antioxidant capacity in PJS, while largely maintaining the presence of heat-sensitive compounds. Regardless of genotype and HPH treatment, in vitro gastrointestinal digestion adversely affected TPC, TAC, AAC, and antioxidant capacity of all PJS. However, the 150 MPa HPH treatment of Saricakaya-1 had the highest values for TPC bioaccessibility and recovered ABTS-ARA after in vitro gastrointestinal digestion (p < 0.05). Considering the overall data, 150 MPa HPH treatment can be recommended as an innovative approach to obtain minimally processed PJS to meet new trends in consumer demand.
