DAidzein and Genistein Content in Tempeh Product from Several Loval Soybean Varieties.pdf Restricted to Repository staff only Download (371kB) |
Abstract
Background: Tempeh is a widely consumed food due to its health benefits, affordability, and suitability for long-term consumption. The production process of tempeh from soybeans involves several stages, including soaking, dehulling, and inoculation with Rhizopus oligosporus yeast. Fermentation plays a key role in enhancing the nutritional quality of tempeh, particularly by increasing the levels of aglycone isoflavones. Tempeh contains three major types of aglycone isoflavones: daidzein, glycitein, and genistein. Among these, daidzein and genistein are classified as phytoestrogens due to their structural similarity to endogenous estrogens and their associated health-promoting properties. Objectives: This study examined six soybean seed varieties and their corresponding tempeh products, processed using traditional methods and fermented for three different durations (42, 47, and 52 hours). Methods: Soybean seeds and tempeh samples were extracted using cold extraction method and analyzed for daidzein and genistein content by the standard addition method. Results: The results indicated variations in daidzein and genistein content across the six soybean varieties and among tempeh products fermented for different durations. The tempeh produced from the Dering 1 soybean variety had the highest daidzein content (2.59%), while the Devon 1 variety had the highest genistein content (2.13%) after 47 hours of fermentation. Conclusions: These findings support the potential of tempeh made from local soybean varieties as a functional food, owing to their elevated levels of bioactive isoflavones.
