Changes in nutritional and anti-nutritional compounds during lamtoro gung (Giant Leucaena) germination

Bioactive peptides are widely studied because they offer numerous benefits for human health, as including anti-hypertensive peptides. Bioactive peptides can be produced during germination. An anti-hypertensive peptide based on the inhibitory activity against ACE-I peptide has been reported in germinated lamtoro gung. Therefore, this study evaluated changes in nutrients and anti-nutrients during lamtoro gung germination. This experiment was conducted with a Completely Randomised Design (CRD) with the differences in germination duration as the factor. The results showed that the crude protein content decreased significantly; the lowest protein content (30.75) was found at the 60th hour of germination. The amino acid (AA) can be maintained at the 36th hour of germination with a total amino acid (TAA) of 30.82 g/100 g protein. The levels of tannin, phytic acid, trypsin inhibitor activity, and mimosine decreased by 22.76, 35.11, 98.83, and 98.87 respectively, at the 48th hour germination sample. It also showed an increase in in vitro protein digestibility (61.48). This research proves that germination can retain the nutritional compounds, reduce anti-nutritional compounds, and increase the protein digestibility. © 2025, Instituto de Tecnologia de Alimentos - ITAL.
