Studies on the Impact of Taste-aware Intelligent Analysis of Oral Nutritional Supplements
China108 participantsStarted 2023-04
Plain-language summary
The goal of this observational study is to test the taste perception threshold and palatability interval of different populations and the difference in taste perception between tumor and stroke patients and healthy people by combining manual sensory evaluation and electronic bionic sensory and investigate the taste perception characteristics and demand of enteral nutrition preparations such as Fortimel in tumor and stroke patients, and the difference in taste perception of enteral nutrition preparations with healthy people by combining manual sensory evaluation and electronic bionic sensory. Participants were tested for different taste perception thresholds using a three-point difference test, with samples materials for basic taste stimuli used, i.e. reference substances tartaric/citric acid (acidic), quinine hydrochloride/caffeine (bitter), anhydrous sodium chloride (salty), sucrose (sweet), and quercetin/alum (astringent) were used to prepare different tastes and concentrations of liquids. The subjects will then evaluate the appearance (color, texture), taste, flavor, and texture of the six different flavored enteral nutrition preparations. The subjects will then perform manual sensory evaluation of the appearance (color, texture), odor, taste, texture, and other properties of the 6 different flavored enteral nutrition preparations.
