B Vitamins in Selected Variety Breads Commercially Produced in Major U.S. Cities

ABSTRACT Three enrichment vitamins (thiamin, riboflavin, niacin) and three other (folic acid, pantothenic acid, vitamin B 6 ) B vitamins were determined in 10 types, up to four brands of each type, of variety breads (including tortillas) purchased from four major U.S. cities. In general, bread types traditionally enriched and not containing nonflour components as significant ingredients met the vitamin enrichment standards. In many products, the contents of all six vitamins varied appreciably from brand to brand. In contrast to wholewheat bread and some enriched breads, corn tortillas were consistently low in ail vitamins except vitamin B 6 .
