Abstract

The changes in phytate, phytase activity and in vitro availability of iron and zinc during soaking and sprouting of green and white faba bean (Vicia faba L.) were investigated. Faba bean were soaked for 24 h and germinated for 72 h after soaking for 24 h to reduce phytate content and increase iron and zinc in vitro availability. The results revealed that iron and zinc content was significantly reduced from 28.2 to 39.8 % and 12.5 to 27.6 % for soaking treatment and 38.2 to 38.9 % and 24.5 to 29.2 % for sprouting treatment, respectively. Phytate content was significantly reduced from 26.9 to 32.5 % for soaking treatment and 28.0 to 34.9 % for sprouting treatment, respectively. The results proved that the main distinct point is the change of phytase activity as well as specific activity during different treatment which showed no significant differences between the green and white faba bean. The in vitro availability of iron and zinc were significantly improved as a result of soaking and sprouting treatments.
