Abstract

In India. the citrus fruit JUIce industry being still in its infancy, practically no work has so far been done on the successful preservation of pure citrus juices by methods which entail minimum losses of vitamin-C and at the same time, help in the retention of the original fresh juice characteristics during storage. However, outside India, this problem has been studied from different aspects, notably by Davey"', Joslyn and Marsh 10, von Loeseck3l, Eddy5, Tressler et al. 30, Fitz Patric et al 7 , Clark 2, Loeffler 14, Lueck and Pilcher 15. Moore et al. 1S - 20 , Rohrer and Treadwa1l2 ',. Scanlan and Willard ~27. S~ith et al. 22, Esselen et al. 6 , but none of the workers have so far reported an investigation which deals collectively with all the' methods of preservation, including the modern ones, viz., Deaeration and Flash-pasteurization and their relative effects on the retention of the original ascorbic acid content both during processing as well as storage. along with the effects of sweetening of citrus juices with cane sugar. head-space in the container, type of container, storage temperature, etc. An investigation on the above lines was therefore undertaken in the Indian Institute of Fruit Technology, Delhi, during 1948-49, the main results of which with respect to ascorbic acid only are briefly dealt with in this paper.
