Abstract

Velvet bean is a native Indonesian legume containing L-dopa, yet it remains underutilized. The aim of this study was to analyze the effects of different types of tempe (soybean, velvet bean, and their combination) on cognitive function, brain histology, dopamine levels, and serum β-amyloid in rats, as well as to identify the parameters most influencing cognitive function, including brain mass and volume, hippocampal neuron count, and dopamine and β-amyloid levels. An experimental study was conducted using a completely randomized design with one factor: the protein source of diet. Five rat groups were included based on protein sources: non-protein, casein control, soybean tempe flour, velvet bean tempe flour, and a combination of soybean and velvet bean tempe flour. This study examined cognitive performance by measuring maze completion time, while brain mass and volume, hippocampus histology for neuron cell counts in the dentate gyrus section, cornu ammonis 1 (CA1), and cornu ammonis 3 (CA3), brain dopamine and β-amyloid serum levels were measured after eight weeks of intervention. Our data indicated that rats deprived of protein had significantly slower maze completion times (p<0.001), underscoring the importance of protein in cognitive processes. Rats treated with non-protein rations had significantly lighter brain masses (p<0.001) than other treatments. Histological analysis of the hippocampus showed that the three types of tempe rations helped maintain the number and density of neuron cells in the dentate gyrus and CA3 of the hippocampus. Additionally, the protein in the ration could increase dopamine levels and suppress serum β-amyloid levels. There was a strong correlation between brain volume and neuron cell density in the dentate gyrus section of the hippocampus with cognitive function. These results highlight the promising role of combination tempe in increasing cognitive function, brain mass and volume, dopamine levels, and suppressing serum β-amyloid.

Abstract

Tempe, a traditional Indonesian fermented soybean product made with Rhizopus spp., is classified based on fermentation duration into fresh (two days), semangit (five days), and bosok (seven days) varieties, fermented at room temperature (28–30°C). Longer fermentation is believed to enhance its antidiabetic properties. The aim of this study was to compare the metabolite profiles and hypoglycemic activities of fresh, semangit, and bosok tempe made from germinated and non-germinated soybeans. Diabetic rat models were used to assess the effects of these tempe types on body weight, blood glucose levels, serum insulin, pancreatic β-cell count, and glycogen content in liver and muscle tissues. Metabolomic profiling was conducted using gas chromatography-mass spectrometry (GC-MS), followed by principal component analysis (PCA) to assess the influence of fermentation stage and germination. Fresh tempe, especially from germinated soybeans, had the highest moisture content. Fermentation duration significantly influenced color, texture, and pH, with bosok tempe showing the most notable changes. Tempe and gliclazide significantly reduced blood glucose in diabetic rats in vivo, with semangit and bosok tempe restoring levels close to normal. However, weight loss was not reversed. Bosok non-germinated tempe induced the highest insulin levels among tempe treatments and improved β-cell count and density to levels comparable with gliclazide. Glycogen stores in the liver and muscle were significantly restored by tempe, with bosok non-germinated tempe showing the greatest effect. GC-MS profiling identified 154 metabolites, of which 63 were annotated. Fermentation and germination shifted the metabolite profile, with bosok non-germinated tempe showing the highest diversity, including amino acids, sugars, and amines. PCA separated samples by fermentation stage, highlighting metabolite accumulation with prolonged fermentation. The findings revealed that bosok tempe from non-germinated soybeans had the highest abundance of bioactive metabolites, including isoflavones, which likely contributed to its superior antioxidant and hypoglycemic potential compared to other tempe types.
