Tempe, a fermented soybean product from Indonesia, showcases how fermentation enhances nutritional value and digestibility. Rhizopus oligosporus, a key starter culture in tempe production, enzymatically enhances carbohydrate, vitamin, and mineral availability from raw soybeans. This process also boosts bioactive compounds such as γ-aminobutyric acid (GABA), recognized for its role as an in…
Folic acid is an important vitamin for fetal development and nucleotide and amino acid metabolism. Corn is one of the good sources for folic acid while tempeh fermentation has been reported to increase folic acid content. To concentrate further, membrane filtration is a promising technology. This study aims to understand the effect of microfiltration conditions towards the increase of folic aci…
