Linum Usitatissimum USDA Herbal Supplement Kosher Certified by QAI The nutty flavor of flaxseeds combined with their large content of omega-3 fatty acids makes them a popular addition to diets. While whole flaxseeds feature a soft crunch, the nutrients in ground seeds are more easily absorbed. These seeds have a high oil content, and although the oil is relatively stable while the seed is intact, refrigeration is recommended to slow the oxidation process and prolong the life of the seed. Raw flax (also known as linseed) seeds contain a cyanogenic glycoside which is toxic if consumed in large quantities (20-30 tablespoons per day). The cyanogenic glycosides are volatile and will readily dissipate when flax is cooked. Flavor - bland, slightly green-grassy taste. Non-irradiated.
