6—Lancaster Farming, Saturday. Oct. 25, 197 5i Shelf life of milk prolonged COLLEGE PARK, Md. • Last fall (1974) the dairy science and agricultural engineering departments at the University of Maryland, here began research on a substitute process for pasteurisation that may increase the shelf life of milk Indefinitely. This resesrch was facilitated by a $24,000 grant from an equipment BERK'S COUNTY DHIA Clarence C. Sattazahn Heidi 22 H Poach 75 H C 9 H q>2 Yi Paul J. Kurtz Angel H Edina H George S.

Both arc Prince Georges county residents. Installation of the equipment last fall and winter was supervised by Dr. Andrew M.

What do potential consumers think of the taste? Other questions have included: How does the new process affect the protein and other nutrients in milk? How does it affect cheese produced from UHT-treated milk. 657 606 681 628 607 19,298 18,394 17,793 17,159 14,446 13.932 19,267 14,420 14.933 14,518 18,061 16.547 15.047 16.042 12.227 16.547 15.047 16.042 12.227 Although the research is not fully completed, it ap pears that the technology involved does provide tremendous potential for future dairy processing operations. 554 573 14,365 13,736 Don’t Freeze Everything Certain foods should not be frozen, because their flavor or texture changes during the freezing process For example cooked egg white toughens, salad greens lose their crispness, raw tomatoes change their flavor and color and become limp and watery, raw ap ples and grapes become soft and mushy, fried foods tend to have a warmed-over taste when reheated 555 14,344 INVENTORY REDUCTION SALE GRAIN DRIERS GRAIN BINS THE MOST EXPERTLY ENGINEERED DRIER AVAILABLE WITH WEATHER SHEILDS FOR POLLUTION CONTROL AND WEATHER PROTECTION. _ _— 4^ Model Bu/Hr Reg Price Sale Price A-8 375 $9,709. $6,796 P-16 450 $11,170 $7,819 ~ * v v For More information call MARTIN DISTRIBUTORS, INC., Lebanon, PA 17042 Phone (717) 866-4906 or (717)866-4555. Informal taste-panel tests of the UHT-trcatcd milk began in September at the University's dairy sales room, located along U.S. highway 1 in College Park. They arc conducted with drop-in customers each Tuesday afternoon under the supervision of Steven R. Framm, a first-year graduate student in food science. Fromm halls from North Bellmore, N.Y. He is a graduate of Nassau Com* munity College and Penn State University. The dairy sales room, site of the taste-testing, has long been famous for its ice cream, made on the premises with milk from Holstein and Guernsey cows at the nearby dairy bam on the College Park campus. The UHT equipment has been installed in Turner laboratory, the University of Maryland’s dairy science research facility in the rear of the dairy sales room at College Park. It represents an accumulation of 20 years of research in both the U.S. and Europe. Earlier experimental UHT sterilizers have been operated in this country at both Michigan State University and the U.S. Department of Agriculture’s Eastern regional research laboratory, formerly located in Washington D.C.
