Germinated rice: An overview of gaba, phenolic components and antioxidant activity

Abstract

This article provides an overview of various studies reporting the correlation and mechanism of increased GABA, phenolic components, and antioxidant reactions in sprouted rice. Sprouted rice is viewed as a functional food because it contains nutrients such as GABA, antioxidants, and other metabolites that are excellent for health. The germination process significantly increases the availability of nutrients such as GABA by 15.4-fold and antioxidant activity by 0.43%. Germination not only adds to the nutrients already present but also introduces new components such as inositol, g-oryzanol, ferulic acid, phytic acid, zinc, tocotrienols, potassium, and prolyl endopeptidase inhibitors. Thus, sprouted rice products can be used as a means of dietary improvement and also as health-promoting foods.
