Fenol total, flavonoid, dan aktivitas antioksidan beras coklat germinasi dari beras hasil budidaya di Provinsi Lampung

Germination process is a method to increase the acceptability of brown rice. In addition,it will increase the content of brown rice bioactive components. This study's purpose is to determine the content of total phenol, flavonoids, and antioxidant activity of germinated brown rice in 3 rice varieties (Mentik Susu, Ciherang, and Pandan Wangi) which are grown in Prov. Lampung. The treatment was designed in a completely randomized block design (CRBD) with 3 replications. The data was processed with variance to determine the effect of treatment on the parameters tested and continued with the Tukey test to determine the differences between treatments. The results showed the content of total phenol, flavonoids, and antioxidant activity of germinated brown rice were influenced by rice varieties and germination time. Germinated brown rice of Ciherang variety showed the highest flavonoid content and antioxidant activity, 16.27mgQE/g ex and 575.36 G/mL, respectively. Germination duration of 24 hours showed the highest content of total phenol, flavonoid, and antioxidant activity, respectively 4.81 mg GAE/g ex, 18.60 mg QE/g ex, and 613.88 G/mL.
