In-mouth mechanism leading to the perception of fat and its consequence on post-prandial lipid metabolism in humans. The particular role of saliva

2014

In humans, the in-mouth perception of dietary fat in food is a complex process involving many sensory modalities (texture, aroma, taste and trigeminal). During food oral processing, a bolus is formed in which saliva is significantly incorporated thus contributing significantly to the perception of fat. In particular, it has been shown that the levels of some salivary characteristics (lipolysis, lysozyme, flux, antioxidant status, level of carbonic anhydrase and proteins) are related to the sensitivity of the individual to triolein and oleic acid. Interestingly, the involvement of some of these salivary variables in the perceived intensity and preference towards model oil emulsions was also …
