The Effect of Refrigerator Storage on the Keeping Qualities of Pasteurized Milk

Considerable attention has been directed recently to the problem of the keeping quality of milk in the household refrigerator. The economy of alternate-day or 3-day-a-week delivery of milk was amply demonstrated during the war years with the result that most distributors would prefer to retain this practice. On the other hand, some public health officials havequestioned the advisability of maintaining this system of milk distribution because of the highly perishable nature of the product. Under the 3-day-aweek system of delivery the product is consmned in from 1 to 4 days after pasteurization. Therefore, to justify such a practice, we must assure the consumer that the product delivered will retain its initial high qualities for at least 4 days.
