All rights reserved Physico-Chemical Properties, Bioactive compounds, and In Vitro Biological Activities of Goji Berry Juice ABSTRACT BOOK startpage: 635 endpage: 636 https://unilib.phaidrabg.rs/o:6223 Ilić, Tijana Krgović, Nemanja Milenković, Milan Kodranov, Igor Vidović, Bojana 2024 eng Goji berry (Lycium barbarum L.) is a rich source of bioactive compounds with long-term use in diet and for medicinal purposes. The aim of the study is to analyze the physico-chemical properties and bioactive compounds of goji berry juice from L. barbarum fruits cultivated in Serbia. In addition, the antioxidant activities were investigated using five different spectrophotometric micro assays (DPPH, ABTS, CUPRAC, FRAP and beta-carotene/linoleic acid bleaching inhibition) and the antidiabetic potential towards two enzymes (alpha-amylase and alpha-glucosidase). Apart from good sensory acceptability, the results suggest that goji berry juice can be used as a good source of bioactive compounds such as polyphenols (194.5 ± 3.88 mg GAE/100 mL), flavonoids (70.30 ± 5.11 mg CE/100 mL), carotenoids (204.6 ± 0.06 mg/100 mL), polysaccharides (375.2 ± 12.46 mg Gl/100 mL) and minerals, especially potassium and copper. The study showed that juice has good antioxidant activity and a dose-dependent antidiabetic potential. Obtained results suggest that consumption of goji berry juice can provide natural antioxidant compounds and can be considered as a functional ingredient with good sensory quality, especially for people with diabetes. info:eu-repo/semantics/conferenceProceedings application/pdf 3962935 bytes
