The sensory properties of food influence food choice, digestion and metabolism. The properties arising from a food’s form, in particular, can alter nutritional outcomes through multiple mechanisms operating at cognitive, orosensory, gastric and intestinal levels of food processing. Expectations regarding a food’s form can influence satiety, sensory...
Article
Evidence supporting a “taste” cue from fat in the oral cavity continues to accrue. The proposed stimuli for fat taste, non-esterified fatty acids (NEFA), are released from food through hydrolytic rancidity and lipase activity derived from foods or saliva. NEFA must then be released from the food matrix, negotiate the aqueous environment to reach ta...
