Phytochemical screening and proximate analysis of soybeans (Glycine max) variety Gamasugen 1 and Gamasugen 2 derived from gamma rays irradiation

Abstract

Soybean is very widely used in Indonesia, especially as a raw material for processed foods such as tofu and tempeh. This study aims to analyze the phytochemical content and proximate of variety irradiation soybean seeds Gamasugen 1 and Gamasugen 2. Phytochemical and proximate analysis of the seeds of soybean were carried out with quantitative and qualitative analysis. The proximate study analyzed included water content (oven method), ash content (furnace method), fat content (Soxhlet method), and crude fiber content (acid alkali digestion method). The results of phytochemical testing show that both soybeans (Gamasugen 1 and Gamasugen 2) contain flavonoid as quercetin, alkaloid, saponins, phenolic, triterpenoid, and glycoside. The proximate analysis results showed that Gamasugen 1 soybeans had a moisture content of 8.22%, lower than Gamasugen 2, which was 11.67%. Gamasugen 1 soybean content is 4.61%, lower than Gamasugen 2, which is 4.86%. Gamasugen 1 soybeans have a fat content of 14.50%, more economical than Gamasugen 2, which is 15.51%. Gamasugen 1 soybeans have a fiber content of 14.56%, higher than Gamasugen 2 soybeans, which is 9.96%. The conclusion shows the most top proximate analysis of soybean is found in fat content (Gamasugen 2) which is 15.51% and the lowest level is found in ash content (Gamasugen 1) which is 4.61%.
