Total folate: diversity within fruit varieties commonly consumed in India
2010
Folate concentrations in selected fruits were measured using the trienzyme extraction and microbiological assay with Lactobacillus casei (subsp. Rhamnosus) as an assay organism. Fruits were purchased from different retail outlets at Coimbatore, Tamilnadu, India and were analyzed for total folate content. The folate content in all fruits varied considerably on a fresh weight basis from 10 to 328 μg/100 g, with tropical fruits ranging between 10 and 211 μg/100 g, temperate fruits from 11 to 328 μg/100 g, and the subtropical fruits in the range of 9–237 μg/100 g. Amongst all fruits, plum had the highest content of folate (328 μg/100 g). Data analyzed will assist dietary studies to estimate and evaluate the adequacy of folate intakes of the population, to formulate experimental diets for folate bioavailability studies, and to revise dietary recommendations for the population. In addition, the data will assist the health authorities in planning and executing strategies for intervention programs.
