Bioavailability of dietary folate might be impaired by the polyglutamate chain to which∼ 70%
of dietary folates are bound. This chain must be removed enzymatically in the intestine …

The intestinal absorption of folate occurs at the monoglutamyl level, and an important
measure of food folate bioavailability is how much folate from the food reaches the intestinal …

A reversed-phase high-performance liquid chromatographic method with fluorescence and
ultraviolet detection was used to evaluate the different steps in folate analysis to detect and …

Background: Evidence is conflicting as to whether the bioavailability of food folates is
influenced by the extent of their conjugation. Objective: The objective was to compare the …

The influence of different treatments, ie, crushing, high temperature short time (90°
C/4min)(HTST) and low temperature long time (60° C/40min)(LTLT) blanching, acidification …

To provide a tool to study folate bioavailability under controlled conditions, a methodology
was developed to produce extracts representative of natural food folates but removed from …

A liquid chronoat (LG) method was elaborated for determining folates in foods. Folates were
extracted by homogenizing in buffer and heat treatment. A portion was incubated with an …

Folate bioavailability of beef liver, lima beans, peas, spinach, mushrooms, collards, orange
juice and wheat germ was estimated with a protocol of folate depletion-repletion using …

Dietary folate exists mainly as polyglutamyl forms that require deconjugation by Zn-
dependent pteroylpolyglutamate hydrolase prior to intestinal absorption. Because …

Folate bioavailability based on serum folate response curves was estimated after ingestion
of single test foods in 9 men. The area under the curves (AUC) was estimated after intake of …
