Trienzyme treatment appears to be essential for Obtaining the maximum possible value of folate in food items. Trienzyme treatment is performed rising protease and alpha-amylase treatment for the extraction of food folate trapped or bound to protein or carbohydrate matrices, and using traditional folate conjugate for the hydrolysis of polyglutamyl folates that are regularly present in foods. Because the conditions (pH and incubation time) of pretense and alpha-amylase treatments vary among individual foods, it would be labor intensive and time consuming to put together reliable and accurate food folate tables. However, considering the importance of folate nutriture for the maintenance of hearth and the prevention of certain diseases, it is important to establish dependable food folate tables to accurately estimate dietary intake of folate and to recommend adequate dietary folate intake in the general population.
