报告内容简介：

      Human perception is complex system which utilizes different strategies to obtain a stimulus when perceiving fat-containing food. Description of these processes requires knowledge from several disciplines: food science, chemistry, biology, physics and psychology. There are several theories which at some aspects seem contradictory and others where they are complementary. Theories about orals sensation of oil\fat can be classified as following: 1 Fat/oil is perceived when Free fatty acids (FFA) released from triglycerides are detected by chemoreceptors on the tongue surface in taste buds; 2 Somatosensory receptors detect fat/oil texture and neurons perceive it as texture-specific signal; 3 Multimodal perception of fat/oil from food, involving aroma, taste and tactile cues that form a comprehensive stimulus. Instrumental and human tests will be employed for this investigation, whilst instrumental analysis will be the main focus of this project, human studies will be applied whenever necessary in order to obtain supporting evidences. Olfactory, gustatory and somatosensory will be the main sensory cues for the investigation. Visual and audio cues will not be included in this study. Proposed topics of this thesis are as follows: 1 How capable are human individuals in differentiating oil/fat substances from non-oil\fat substances; 2 Individualism of oil/fat sensation; 3 Does salivary lipase influence our sensation of oil/fat; 4 Does oil/fat-related aroma influence our sensation of oil/fat; 5 Will sources of oil/fat (animal or plant) influence our sensation; 6 How effective are currently available fat-replacers in replacing oil/fat from food formulation; 7 Does our brain act differently when sensing oil/fat.
