Abstract
Soybean contains bioactive compounds such as flavonoids, phenolic acids, vitamin C, vitamin E, beta carotene. The content of soy flavonoids such as isoflavones act as antioxidants, anticancer, anti-osteoporosis, antibacterial and antimutagenic. Soybean can be processed into fermented food, one of the fermented foods from processed soybeans is seredele. Seredele is a traditional food typical of the city of Gianyar whose manufacturing process uses natural microbes. This study aims to determine the effect of the type of solvent on the antioxidant activity and bioactive compounds of seredele extract and determine the best type of solvent to produce seredele extract with the highest antioxidant activity. The experimental design used was a randomized block design with 5 types of solvent treatment, namely: 70% ethanol, 90% ethanol, 96% ethanol, ethyl acetate, n-hexane with a ratio of 1:10 to the solvent. This study was grouped into 3 based on the time of the extraction process so that 15 experimental units were obtained. Data analysis was carried out by analysis of variance and if the treatment affected the observed variables, it was continued with the Least Significant Difference test. The results showed that the type of solvent treatment had an effect on antioxidant activity, total flavonoids, ?-tocopherol and total phenol. The best solvent to produce seredele extract with the highest antioxidant activity was 70% ethanol with the following extract characteristics: IC50 antioxidant activity of 183.16 ± 30.88 ppm, total phenol 21.19 ± 1.95 mg GAE/g, total flavonoids 11 .88 ± 0.87 mg QE/g and total ? tocopherol 12587.02± 2419.82 mg 100/g.
