Effective utilization of food wastes: Bioactivity of grape seed extraction and its application in food industry

Grape seeds are rich in nutrients possessing high nutritional and medicinal value. Grape seed extract (GSE) mainly contains 15 phenolic compounds, such as (+)-catechin, (−)-epicatechin, proanthocyanidin, gallate, flavonols and others. Several studies on GSE and its components indicated that it has pharmacological attributes, such as antioxidation, anti-inflammation, anticancer, neuroprotection, lowering lipid, bacteriostatic, and reduced blood pressure. This article reviewed the research progress on the bioactivity of GSE and its application in foods in order to provide a reference for future studies on the development and utilization of grape seeds.
