Chemoprotectants from crucifer seeds and sprouts

摘要

Disclosed is a method for extracting chemoprotectant precursors comprising: forming an aqueous extract of crucifer seeds or sprouts; contacting the aqueous extract with about 8 to about 12 weight percent of an adsorbent; and separating the adsorbent from the aqueous extract to provide a chemoprotectant precursor enhanced extract, wherein the method provides a chemoprotectant precursor enhanced extract having a ratio of alkyl glucosinolates to indole glucosinolates of at least 30:1. Also disclosed is chemoprotectant precursor enhanced extract produced by said method and a food product containing said chemoprotectant precursor enhanced extract.
