| Summary: | Jack Beans and Velvet Beans are good protein sources; therefore, they are prospective as tempe ingredients. However, the presence of anti-nutritional compounds may limit their use for food. This study aimed to evaluate the effects of selected detoxification methods on the tempe characteristics of both beans. Three detoxification treatments (3 h boiling in water, 3 h boiling with husk ash, and 1.5 h pressure-cooking) were applied as the bean preparations before processing into tempe. The results showed that all treatments effectively reduced anti-nutritional and toxic compounds. Pressure-cooking resulted in the highest hydrogen cyanide (HCN) reduction (96.62 %), followed by boiling with husk ash (93.82 %) and boiling in water (89.74 %). Likewise, the highest phytic acid reduction was noted in pressure cooking (83.10 %), while it was insignificant for both boiling treatments (58.50 %). However, pressure cooking decreased the amounts of proteins, lipids, and dietary fibers, as well as the hardness and lightness values. These findings suggest that an optimized pressure-cooking conditions is likely required to minimize such losses in nutrients and lightness while being practically safe for consumption. All detoxification methods exhibited similar sensory acceptance besides color. Jack Bean tempe was preferred over Velvet Bean due to its similar color, taste and texture to soybean tempe, while Velvet Bean tempe contained slightly higher protein, lipid, and dietary fiber. Overall, this study provides valuable information to support the utilization of indigenous legumes for tempe making. |
