Which enzyme is activated during sprouting to initiate the breakdown of phytic acid in grains and legumes?

Answer

Phytase

The process of sprouting triggers significant biochemical shifts within the dormant seed or grain. A key change involves the activation of the specific enzyme known as phytase. This enzyme’s primary function in this context is to begin the decomposition of phytic acid, which is a compound naturally present in grains and legumes. Phytic acid acts as a storage form of phosphorus but also has the negative effect of binding to essential minerals like iron, zinc, and calcium within the food matrix, thereby hindering their proper absorption in the human digestive tract. By activating phytase, the sprouting process effectively liberates these minerals, dramatically improving their bioavailability for the consumer. The activation of this specific enzyme is central to the enhanced mineral absorption claimed for sprouted foods.
