[Effect of meat pâtés of different composition on gastric secretory function]

Experiments on 4 dogs with isolated Pavlovian pouches were made to study the action on gastric secretion of a new type of a beef paté in which 20% of basic raw material was replaced by precipitated blood plasma proteins (a sample under study) and of a beef paté of a conventional composition (a control sample). Both paté samples were found to provoke a characteristic gastric juice secretion which strongly differed from the secretion pattern during beef feeding. This was determined by the presence in the patés of a significant amount of fat and by the homogenized nature of the paté mass. Gastric juice thus obtained was marked by a slightly decreased acidity, low content of hydrochloric acid pH 1.7-2.6, and moderate pepsin concentration. Replacement in beef paté of 20% of basic raw material by precipitated blood plasma proteins did not provoke any changes in gastric secretion as compared to that seen during intake of patés of a conventional composition.
