Effect of Refrigeration on Ascorbic Acid Content of Canned Fruit Juices after Opening1

Vitamin C contents of citrus fruit and their products: a review

“…From the point of view of the consumer, numerous investigations (Scoular and Willard, 1944; Moore et al, 1945;Feaster et al, 1950;Lopez et al, 1967;Horton and Dickman, 1977) have shown that fresh processed single-strength and reconstituted citrus juices may be kept in a refrigerator for a reasonable length of time (about 4 weeks) without serious loss of vitamin C. Degradation of vitamin C in open containers (glass, plastic, or cans) is minimal if juice is stored at cold temperatures. Even when juice is stored at room temperature, storage time is limited more by loss of palatability than by loss of vitamin C potency .…”
