Prospective Sensory Evaluation of Preparatory Methods of Elemental Diets

Abstract

ABSTRACT. Palatability of elemental diets has been the greatest obstacle to their successful long-term oral administration. Two elemental diet products, A and B, were evaluated in' four preparatory methods for acceptability in a prospective double-blind study. The elemental diets evaluated were most acceptable when prepared in the form of Jello (57% receiving acceptable scores) followed by frozen Tang (27% receiving acceptable scores) and those prepared with Flavor Packets (18% receiving acceptable scores). The Kool-Aid method of preparation was not accepted well (6% receiving acceptable scores). Product B was more acceptable than A in palatability and overall acceptability in the methods tested. To successfully administer elemental diets when a nasogastric tube is not employed, we recommend that these diets include formulations with Jello, frozen Tang, or Flavor Packets and that they be prepared by the dietary department. It is recognized that alterations in the composition of elemental diets result from the addition of flavoring agents. The significance of these alterations should be considered for each patient.
