Obesity interferes with the orosensory detection of long-chain fatty acids in humans
2014
Background: The association between the orosensory detection of lipids, preference for fatty foods, and body mass index (BMI; in kg/m 2 ) is controversial in humans. Objective: We explored the oral lipid-sensing system and the orosensory-induced autonomic reflex system in lean and obese subjects. Design: Lean (BMI: 19 to ,25; n = 30) and obese (BMI .30; n = 29) age-matched men were enrolled. Their oral threshold sensitivity to linoleic acid (LA) was determined by using a 3-alternative forced-choice ascending procedure, and their eating habits were established by the analysis of 4 consecutive 24-h food-consumption diaries. The effect of brief oral lipid stimulations on plasma triglyceride [(…
Evolution of microbiological and chemical parameters during red wine making with extended post-fermentation maceration.
2014
Abstract The aim of the present work was to investigate the microbiological, chemical, and sensory characteristics of red wine subjected to post-fermentation maceration that was extended to 90 days. For this purpose, the ‘Aglianico di Taurasi’ grape was used as a case study. The total yeast concentration increased until day 40 of maceration and decreased thereafter, whereas the concentration of lactic acid bacteria slightly increased. Dekkera/Brettanomyces spp. and acetic acid bacteria were not detected. The yeast community was composed of Saccharomyces cerevisiae, Zygosaccharomyces bisporus, Metschnikowia pulcherrima, Hanseniaspora guilliermondii, Hanseniaspora uvarum, Pichia guilliermondi…
Obesity alters the gustatory perception of lipids in the mouse: plausible involvement of lingual CD36. : Obesity decreases the fat preference
2013
International audience; A relationship between orosensory detection of dietary lipids, regulation of fat intake, and body mass index was recently suggested. However, involved mechanisms are poorly understood. Moreover, whether obesity can directly modulate preference for fatty foods remains unknown. To address this question, exploration of the oral lipid sensing system was undertaken in diet-induced obese (DIO) mice. By using a combination of biochemical, physiological, and behavioral approaches, we found that i) the attraction for lipids is decreased in obese mice, ii) this behavioral change has an orosensory origin, iii) it is reversed in calorie-restricted DIO mice, revealing an inverse …
The rs1527483, but not rs3212018, CD36 polymorphism associates with linoleic acid detection and obesity in Czech young adults
2018
AbstractRecent evidence has raised the possibility of the existence of a sixth taste modality – that is, taste for fat – which is mediated by lingual CD36 and plays a role in obesity. Consequently, the genetic polymorphism of CD36 has been shown to be associated with altered oro-sensory detection of dietary lipids. In the present study, we investigated the relationship between oro-sensory perception of linoleic acid (LA), two CD36 polymorphisms (rs1527483 and rs3212018), obesity parameters and craving habits for dietary lipids in young Czech adults. We also sequenced 5 and 6 exons of CD36 to trace out any new mutation that might be responsible for the difference in taste perception. We obse…
Contribution à l'étude des « goûts de lumière » dans le vin de champagne *. 1. Aspects analytiques - Dosage des mercaptans et des thiols dans les vins
1977
<p style="text-align: justify;">Plusieurs accidents appelés « goûts de lumière » ou « goûts de réduit » ont été observés dans les vins de champagne au cours de ces dernières années. Dans ce travail, nous avons mis au point une méthode d'appréciation de ces goûts par dosage des groupements thiols ou mercaptans dans les vins. L'analyse comparative montre une bonne concordance entre la concentration en groupements thiols et l'appréciation gustative.</p><p style="text-align: justify;">+++</p><p style="text-align: justify;">For some years, accidents called « light tastes » or « reduced tastes » have been occured in Champagne wines; a method for thiols and mercaptans…
Use of stevia and chia seeds for the formulation of traditional and vegan artisanal ice cream
2021
Abstract Gelato is the name of the Italian-style artisanal ice cream, a nutritious product widely consumed in different parts of the world. Due to the high content in simple sugars, ice cream should be consumed moderately by diabetic patient. This research aimed to create artisanal ice cream, using Stevia rebaudiana, a plant well known for its sweet taste and its hypoglycemic effect. Traditional and vegan ice cream were formulated using stevia and chia seeds, in order to obtain products with appreciable rheological, textural and sensorial properties. Physical and sensorial properties of the ice cream formulation containing milk protein (traditional) or vegan substitute, were evaluated. Resu…
Cross modal interactions: way to counterbalance salt reduction in solid foods?
2008
International audience; Four model cheeses varying in texture (2 Dry Matter (DM) levels; 2 Fat/DM levels and 1 salt level) were designed and flavored with 3 commercial tasteless aromas (“Comté Cheese”, Sardine and Carrot) differently associated with salty and cheesy food products. Thirty untrained subjects were instructed to evaluate taste intensity (sourness, bitterness, saltiness and sweetness), aroma intensity, texture attributes (firmness, moistness and graininess), aroma congruency with the product and their hedonic appreciation of the 12 flavored and 4 unflavored model cheese samples. A comparison of the saltiness perception of the flavored and unflavored model cheeses revealed cross-…
Dietary Sugar and Fat Exposure : Determinants and Links with Sweet Taste Liking and Fat Sensation Liking
2017
Context : Dietary exposures in the first year of life could play a role in the development of food preferences in children. Aims : To characterize dietary sweet and fat exposures in infancy and to study their links with sweet taste and fat sensation liking in school-aged children. Methods : During the first year, dietary sweet and fat exposures were assessed with a nutritional approach in the EDEN study and with a sensory approach in the OPALINE study. Next, early factors related to these dietary sweet and fat exposures were analyzed. Associations between the nutritional sweet and fat exposure and sweet taste and fat sensation liking scores in 9-to-12 y old children in the EDEN study were s…
Fiktiiviset reseptit ja mahdottomat ateriat kirjallisen komiikan lajina

Fictitious recipes, impossible meals: a subgenre of comical literature The article looks into ctitious and imaginative food recipes and comical potentiality of such food related text types as listings of ingredients, foodstuffs, dishes, or portions. The focus is on imaginary, fantastic, and impossible meals and recipes: portions that could not be implemented in the real world. The recipe as a form is covered from genre-theoretical, narratological, poetic and procedural perspectives. The special point of reference is experimental literature and its interests in literary forms, rules, constraints, and procedures − the terms that could be used to define also culinary recipes as codes or script…
Mechanisms of gustatory perception of dietary lipids : cross-talk with bitter taste and endocannabinoid receptors
2018
Obesity is one of the major public health problems at the beginning of the 21st century. Its prevalence is increasing steadily, especially among children. This observation is not insignificant because obesity is generally associated with various serious pathologies (type 2 diabetes, hypertension and cancer, etc.). Thus, investigations into the mechanisms involved in the taste perception of dietary lipids could shed light on their roles in the incidence of obesity.Several studies have demonstrated the role of endocannabinoids and bitter foods in obesity. Thus, we studied the cross-talk of cannabinoid receptors and bitter taste with lipid taste. This thesis has two components: cannabinoid rec…
