The seeds contain saponins, though in small quantities, which are removed by soaking seeds in water overnight and rinsing thoroughly before further processing. [45] Another method involves chemical processing, whereby gradual, controlled heating of the seeds detoxifies them, allowing nutrients to be bioavailable for digestion. [20]
Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds, or other structures experience further growth. In the field of nutrition, the term signifies the practice of germinating seeds (for example, mung beans or sunflower seeds ) to be eaten raw or cooked ...
