The present invention relates to glucosinolates produced from agricultural by-products and wastes. The present invention relates to a method for producing glucosinolates, especially glucoraphanin, from plants of the family Cruciferae. More importantly, a method for producing glucosinolates from agricultural by-products and wastes is provided. The method comprises providing a mixture of glucosinolate-containing plant material and a liquid, heating the mixture to inactivate enzymes in the plant material, contacting the heat-inactivated mixture with an anion exchange membrane, whereby at least a portion of the glucosinolates Extracted from the liquid and absorbed onto the anion exchange membrane, from which glucosinolates are released. More preferably, the steps of extraction and release are repeated at least once. The glucosinolate produced by the method of the invention can be introduced into various foods, medicines and health supplements. |
