Effect of Genetic Variation on Salt, Sweet, Fat and Bitter Taste
Background: Taste is one of the primary determinants of food intake and taste function can be influenced by a number of factors including genetics. However, little is known about the relationship between genetic variation, taste function, food preference and intake. Objective: To examine the effect …

Rapid Expansion and Specialization of the Bitter Taste Receptor Family in Amphibians
In classic sensory literature, bitterness is viewed as an early-warning system for toxic or spoiled foods. In vertebrates, bitterness is detected with a family of intronless G protein-coupled receptors called TAS2Rs. TAS2Rs are well studied in the human and mouse mouth, but recent studies have …

Study on the effects of bitter taste receptor on the rat pulmonary artery
Bitter taste receptors (TAS2Rs) have been implicated in roles other than taste perception. TAS2R agonists exert vasorelaxant effects in vascular smooth muscle from guinea pig, mouse and humans. We hypothesis that bitter taste agonists could modulate the pulmonary artery vascular tone. The …

Neuroanatomical Maps and Taste Reactivity to Sweet, Umami, and Bitter Taste in the PBN of C57BL/6J Mice
… Humans can distinguish at least five different taste qualities, sour, salty, bitter, sweet, and umami (the savory taste of certain amino acids). In neuroscience research, behavioral testing is used to measure the ability of rodents (including inbred mice) to discriminate between the different …

Microencapsulation of tributyrin to improve sensory qualities and intestinal delivery
… of butyric acid, is characterized by a highly bitter taste and negative odor attributes. Its use in the maintenance of intestinal health and treatment of intestinal disorders shows promise. However, due to the negative sensory qualities and necessity to target the intestinal epithelium, TB has …

Sensitivity to chemical stimuli plays a fundamental role in the food preferences. Examples in the evolutionary scale: 1. Role of the walking leg chemoreceptors in the red swamp crayfish Procambarus Clarkii 2. PROP bitter taste sensitivity and its nutritional implications in Humans
… for crayfish population control programs. Taste sensitivity varies greatly in humans, influencing eating behavior and therefore may play a role in body composition. PROP bitter taste sensitivity is the most studied example of the individual variability of taste sensitivity. Some studies …

Arc expression in the parabrachial nucleus following taste stimulation
… to study the complexities of the mammalian taste system; however molecular mechanisms of taste processing in the early structures of the central taste pathway remain unclear. More recently the Arc catFISH (cellular compartment analysis of temporal activity by fluorescent in situ …

Neural and Psychological Mechanisms of Oral Sensation
… Oral sensory processing extends beyond taste perception, the nerves that innervate the mouth and carry taste information to the brain also carry chemosensations, thermal sensations and somatosensations. While a great deal is understood about oral chemo and thermal perception, this thesis …

Maternal methamphetamine use during pregnancy and subsequent neurodevelopmental and psychological sequelae in the child - a Cape Town experience
… obtainable, odourless, white powder, which has a bitter, taste, but dissolves easily in water or alcohol. Known as, amongst others, ' speed', 'ice', 'crystal', 'chalk', 'glass', 'crank', and locally, 'tik', it can be smoked, snorted, orally ingested, injected intravenously or even administered …

Nature and nurture on picky eating behavior in early childhood
… Individual genetic variation in genes related to bitter taste was associated with picky eating, suggesting that children who are sensitive to bitter taste are more likely to be picky eaters. We also identified an association between picky eating and individual genetic variation in genes related …

Insights of Taste Masking from Molecular Interactions and Microstructures of Microspheres
The effects of taste masking are determined by interactions between drug and excipients as well as the microstructures of the particulate drug delivery systems (DDS). Cyclodextrin (CD) is a widely used taste masking agent, to which the relationship between kinetic parameters (Ka and Kd) of a drug …

QUANTIFICATION OF ASPARTAME IN LOZENGES AND TABLETOP SWEETENERS VIA MULTIPLE PARAMETER MANIPULATION BY USING DISSOLUTION STUDIES WITH UV-VIS, ULTRA-HPLC, AND MATHEMATICAL DRUG MODELING
… found in many pharmaceutical drugs to mask the bitter taste of the active pharmaceutical ingredient (API). For instance, lozenges are solid intraoral dosage forms intended to slowly release the API into the oral cavity. Aspartame is used in lozenges to impart a sweet taste while an API is …

ETHNOBOTANICAL SURVEY IN VALMALENCO (SONDRIO, ITALY): STUDY AND ENHANCEMENT OF THE PLANT AND CULTURAL BIODIVERSITY
… with the investigation on the preparation’s bitter taste, described by local people as responsible for the traditional therapeutic effect. Thus, preliminary evaluations concerning the interaction of the identified bioactive compounds with bitter taste receptors (TAS2R46) were evaluated …

Investigating sensory characteristics and flavor profiles of ten cucumber cultivars using descriptive and sensory instrumental analysis
… analysis of volatile aroma and non-volatile taste compounds. QDA, using a trained panel (n=10), identified and quantified 14 flavor descriptors for 10 cucumber cultivars. SPME-GC-MS was used to identify 145 volatiles in both the flesh and peel. Sugars (glucose, fructose, sucrose) and acids …

Butyrate-Induced Expression of Proglucagon: Implications for Enteroendocrine Signaling and Intestinal Growth
… we silenced the SCFA receptor GPR43 and the bitter taste receptor T2R38 and revealed that butyrate no longer had the capacity to stimulate increased proglucagon abundance. Additionally, we also examined the abundance of SCFA transporters and noted increases in SLC5A8 in the ileum and MCT-1 in …

The flavor impact of G-Rg1 and G-Rb1 on the taste perception of ginseng
… can be added to a product before imparting its bitter taste into product formulations. There are two ginsenosides present in ginseng that elicit all benefits expected from an energy drink as well as memory enhancement, ginsenoside Rb1 and Rg1 (G-Rg1 and G-Rb1). The main goal of this study was to …
