Genetics of Sensory Thresholds: Individual Taste Reactions for Different Substances.

Genetic and Molecular Basis of Individual Differences in Human Umami Taste Perception

Umami taste (corresponds to savory in English) is elicited by L-glutamate, typically as its Na salt (monosodium glutamate: MSG), and is one of five basic taste qualities that plays a key role in intake of amino acids. A particular property of umami is the synergistic potentiation of glutamate by purine nucleotide monophosphates (IMP, GMP). A heterodimer of a G protein coupled receptor, TAS1R1 a...

Individual differences in the chemical senses: is there a common sensitivity?

Taste, smell, and chemical irritation (so-called trigeminal sensation) combine in our daily experience to produce the supramodal sensation of flavor, are processed by partly overlapping neural mechanisms, and show functional interconnectivity in experiments. Given their collaboration in flavor formation and the well-established connections between these senses, it is plausible that polymodal de...

Genetics of Sensory Thresholds: Variations within Single Individuals in Taste Sensitivity for PTC.

Diurnal Variation of Sweet Taste Recognition Thresholds Is Absent in Overweight and Obese Humans

Sweet taste thresholds are positively related to plasma leptin levels in normal weight humans: both show parallel diurnal variations and associations with postprandial glucose and insulin rises. Here, we tested whether this relationship also exists in overweight and obese (OW/Ob) individuals with hyperleptinemia. We tested 36 Japanese OW/Ob subjects (body mass index (BMI) > 25 kg/m²) for recogn...

Investigation of physicochemical properties of pasta enriched with donalilasalina with the highest amount of bioactive compounds

Enrichment of food products with algae, which are inexpensive substances for human consumption and are rich in protein, carotenoids, antioxidants, omega-3s and fatty acids, are very important in terms of nutritional value. The aim of this study was to investigate the physicochemical and sensory properties of Fermi pasta containing Donalina salina (0, 1.5, 3, 4.5 and 6%) and to determine the bes...
