Nutritive quality of com that was dried by mixing with heatedparticulate media was studied.The com used in phaseI of this study was dried either with a synthetic zeolite (molecular sieve 13X) or sand. The heat-treated com was subjected to in vivo analysis using rats. The com used in phase II was dried by mixing with a natural zeolite (chabazite) or sand. The dried corn in this part of the study was subjected to chemical analysis using laboratory techniques. Results of feeding experiments using rats did not indicate that the nutritive quality of corn dried for 120 - 240 s with the particulate media having an initial temperature of 150 - 250?C was adversely affected. Simi larly, Acid Detergent Fiber analysis did not show a significant reduction in the availability of protein for corn that was dried for 1000 s with the particulate media having initial temperatures in the range of 120-240?C.
