Chemesthesis are the chemically initiated sensations that occur via the touch system. Examples in the mouth include the burn of capsaicinoids in chilies, the cooling of menthol in peppermint, and the tingle of carbonation. It is physiologically distinct from taste and smell, but is increasingly understood to be just as important as these senses for their contribution to flavor, especially with the sustained growth in interest in spicy foods from around the world. Chemesthesis: Chemical Touch in Food and Eating surveys the modern body of work on chemesthesis, with a variety of contributors who are well known for their expertise on the topic. After a forward by John Prescott and an introduction by Barry Green (who originally coined the term chemesthesis 25 years ago), the book moves on to survey chemesthetic spices and address the psychology and physiology of chemesthesis; practical sensory and instrumental analysis; the interaction of chemesthesis with other chemical senses; health ramifications; and the application of chemesthesis in food. The major types of chemesthesis, including pungency/burning, cooling, tingling, nasal irritation, and numbing, are each covered in their own chapter. The book concludes with a look to the future. This is the first comprehensive book on chemesthesis since 1990, when Barry Green and his colleagues edited a volume on the perception of chemical irritants, including those in food. This new book is intended to be a vital resource for anyone interested in the sensory impact of the food we eat, including food scientists, sensory professionals, analytical chemists, physiologists, culinary scientists, and others.

Chemesthesis is the chemical sensibility of the skin and mucus membranes. Chemesthetic sensations are evoked when chemical compounds activate receptors on nerve fibers, skin cells (keratinocytes) and/or mediators of the immune system. The types of sensory qualities are wide-ranging due to the many different types of receptors that are activated by chemesthetic compounds. Sensations elicited by the exposure to these chemicals either orally, nasally or topically are generally referred to as irritating, spicy or pungent. Sub-qualities of irritation include burning, stinging, pricking, itching, heating, cooling, tickling, tingling and/or numbing. The present studies used an integrative multidisciplinary approach to investigate the neural mechanisms underlying various qualities of chemesthesis, as well as the modulation of pain and temperature by irritant chemicals. Our current findings indicate that chemicals that evoke different qualities of irritation can activate common populations of primary and secondary afferent neurons. These broadly tuned neurons activated by chemoirritants project in pathways that ultimately allow discrimination among chemesthetic qualities. We also show additional evidence that TRP channel agonists not only induce irritation, but also modulate thermal responses of Vc and spinal cord neurons and thermosensitivity in behavioral experiments.

COVID-19 is an infectious disease that spreads quickly, requires hospitalization for some patients, and has prolonged effects on the lungs and other body organs. Two early prevalent symptoms of the disease are olfactory and gustatory dysfunction. While most patients regain chemosensory function following recovery from COVID-19, some patients have lingering chemosensory abnormalities. This thesis is focused on identifying a methodology suitable for assessing chemosensory function in the dental clinic. Identifying suitable tests will allow dentists and oral medicine specialist to detect COVID-19-related sensory abnormalities as well as monitor recovery of sensory function over time. Objective: to assess the ability of selected objective measures of olfactory, gustatory, and chemesthesis (oral trigeminal nerve) function to detect alterations in sensory function in a cohort of patients who have recovered from COVID-19. Subjects recruited through a flyer and social media advertising took an online survey based on one developed by the Global Consortium for Chemosensory Research (GCCR, https://gcchemosensr.org). The survey asked questions about COVID-19 diagnosis and symptoms, including changes in smell, taste, and chemesthesis function. Subjects completed objective testing of chemosensory function at the University of Washington Oral Medicine Clinic. Olfactory sensitivity was assessed using the Smell Identification Test (SIT). Gustatory sensitivity was evaluated using a modification of the NIH Toolbox protocol for assessing gustatory function in adults. Chemesthesis was assessed using a capsaicin-containing pullulan-based dissolving strip. All subjects were also tested using semi-quantitative sensory testing to assess trigeminal function in various receptive fields (V1, V2, V3). Psychological assessments included the Patient Health Questionnaire (PHQ-9) and General Anxiety Disorders (GAD-7) scales. Subjects completed a medical review form. An intra-oral examination and dry mouth assessment were also performed. Eleven subjects responded to advertisements and completed the online survey. Nine completed the study protocols. Four of those completing the study had a prior COVID-19 infection, while five did not report prior COVID-19 infection. For those four subjects with prior COVID-19 infection, two self-reported changes in olfaction with COVID-19 infection, two self-reported changes in sensitivity to tastes with COVID-19 infection, and one self-reported change in chemesthesis with COVID-19 infection. One of the two COVID-19 patients reported that olfactory sensitivity had subsequently recovered, while the other reported lingering reductions in olfactory sensitivity. Both patients with taste issues during COVID-19 self-reported that taste function had recovered to “excellent sense”. The patient with COVID-19-related deficits in chemesthesis self-reported lingering loss of sensitivity to spicy foods. Objective testing with SIT failed to discriminate the case with lingering olfactory dysfunction from controls. No evidence of taste dysfunction was observed in any of the cases compared with controls. Objective testing with the capsaicin strip confirmed a lack of sensitivity to capsaicin in the case reporting a lingering loss of chemesthesis. Semi-quantitative testing of the trigeminal receptive fields did not reveal any abnormalities among cases. An abnormal finding was observed in one control. Although the SIT is considered a gold-standard clinical measure of olfactory dysfunction, it did not detect smell loss in a single patient with lingering olfactory complaints. No patients reported lingering taste concerns, so the usefulness of the NIH Toolbox protocol for monitoring COVID-19-related taste loss could not be assessed. The finding that a patient with self-reported lingering chemesthesis loss also had a muted response to the capsaicin-containing pullulan-based dissolving strip indicates that this test may be helpful in detecting, quantifying, and monitoring chemesthesis issues in long COVID.

Chemesthesis is the chemical stimulation of receptors on somatosensory neurons usually by noxious chemicals leading to irritation. Transient receptor potential channels play a major role in detecting chemesthetic stimuli and are found in a wide variety of organisms, from yeast to humans. Currently, there are no reports of TRP channels in earthworms. Earthworms, including Lumbricus terrestris, aerate and enrich soil providing a suitable habitat for plants. Hence, chemicals in the soil which repel earthworms could have deleterious effects on plant growth. Allyl isothiocyanate, a prototypical TRPA1 agonist, has been used as an expellant for sampling earthworms, suggesting that earthworms possess TRPA1 channels. We began the search for TRPA1-like channels in earthworms using electrophysiological, immunohistochemical, behavioral and cell dissociation/calcium imaging techniques. We obtained responses from segmental nerves to tactile stimulus, 50mM AITC and pH 3.8, 4.0 and 4.2. Some cells in the epidermis displayed positive immunoreactivity for Drosophila and human TRPA1 homologs. L. terrestris detected and avoided ATIC and cinnamaldehyde (another TRPAI agonist) but not capsaicin (a TRPV1 agonist) in air and soil T-maze behavioral assays. We were able to dissociate cells from L. terrestris epithelium and ventral nerve cord, but could not use them in calcium-imaging experiments.

Excerpt: An acquired taste often refers to an appreciation for a food or beverage that is unlikely to be enjoyed by a person who has not had substantial exposure to it, usually because of some unfamiliar aspect of the food or beverage, including a strong or strange odor (e.g. stinky tofu), taste (such as bitter teas or hot spices), or appearance. Acquired taste may also refer to aesthetic tastes, such as taste in music or other forms of art. The relationship between taste in food and taste in art is subject to much discussion. For more on non-gustatory taste, see the article taste (sociology). The process of acquired taste looks very much like a form of adaptive preference formation (as described by Jon Elster). An...
