VITAMIN CONTENT OF PRUNES AS AFFECTED BY STORAGE AND OTHER FACTORS¹

Abstract

A new study of the nutritive properties of prunes was undertaken in this laboratory recently, to determine more definitely the place of this cheap and abundant fruit crop in the diet and t o discover effects of methods of storage and handling on these properties. The study was divided into three parts:(1) the assay of freshly harvested and variously stored prunes f o r vitamin content; (2) the determination of the anti-anemia value of prunes and prune products; and ( 3 ) the evaluation of prunes and prune paste as a constituent of dog foods. The results of each of these studies are reported separately, and this paper covers only the first.
