What You Need to Know
Cold‑water soaking leaches saponin glycosides from the seed coat, while mechanical abrasion separates the pericarp without damaging the embryo. Subsequent sun‑drying reduces moisture to 10–12 % to inhibit microbial growth, and low‑heat toasting at 150 °C inactivates lipoxygenase enzymes and further reduces residual saponins, preserving essential amino acids.
