Abstract

EXPERIMENTAL PROCEDURE The first approach to this problem was made by determining the loss of vitamin C immediately after harvesting the vegetables. Samples of the different vegetables were placed in the acid-extraction solution at the garden Tohile other samples were packed in crushed ice and taken to the laboratory within one hour. Assays lyere made on all samples immediately upon arrival in the laboratory. Those samples packed in crnshed-ice containers r e r e held for further storage in the containers both a t room temperature and at a temperature of 6 to 7"C.(42.8 to 44.6"F.). Samples were removed from the crushed ice and placed in the hydrator of a 'Supported in part by a grant from the Wisconsin Ice and Coal Company, Milwaukee, Wisconsin. We are indebted to Earl and Loraine Cardinal for carrying ont some of the studies reported in this paper.
