No-Calorie Powder May Substitute for Foods gamy     George E. Inglett of the U.S. Department of Agricultures BiopolymerResearch Unit in Peoria III invented a no-calorie juicyten up substitute called Z-Trim.It is a mix of miserable fibers do from the hulls of grains. It can replace thefat and some of the carbohydrates in foods such as chocolates, brownies, cheese,and ground beef. He spent three years trying to perfect Z-Trim to be glistenbecause he made it out of tough hulls of corn, oats, and rice. He first crushedthe hulls with a solution of hydrogen peroxide. He washed the peroxide move out incentrifuge. After this step it was still too large, so he put the pieces backthrough the first step of the hydrogen peroxide and the centrifuge. That madeit smooth. Now, it is a fine, white cellulose powder that can be made into agel by adding water.     Inglett also developed Oatrim. This is made up of a digestible fiberfrom oat flour that pro vides four calories per gram.     Z-Trim compargond to another fat substitute, olestra, is different.Olestra can cause gastrointestinal distress and take vitamins and carotenoidsout of the body. The in the altogether substitute does not have those affects. Inglett saysthat you should eat more of the kind of fibers that settle up Z-Trim to reducethe chances of getting intestinal disorders.     But there are some people who argue with Ingletts theory on his newsubstitute. "I wouldnt expect Z-Trim to have the same kinds of problems asolestra," says Margo Wootan, a senior scientist at the Center for Science in thePublic Interest in Washington, D.C. " type is already found in our diet, whileolestra is a synthetic chemical. on that point is also concern for the "microbialstability" of foods containing Z-Trim. "Whenever you remove the lipid materialand replace it with water," says Thomas H.
