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…
Evidence of regional differences in chlorine perception by consumers: sensitivity differences or habituation?
2014
Chlorinous flavors are a leading cause of customers9 dissatisfaction with drinking water. Potential differences in chlorine perception were investigated by conducting sensory testing experiments in France and Spain to assess consumers9 sensory sensitivity (chlorine flavor detection threshold and supra-threshold intensity) as well as their liking of and acceptability for chlorinated solutions. In both countries, two groups of panelists were constituted based on their water drinking habits (tap vs. bottled water). Chlorine flavor detection threshold was found to vary depending on countries (0.17 mg/L Cl 2 in France and 0.56 mg/L Cl 2 in Spain). Taking into account that mean flavor detection t…
Dysplasia in oral lichen planus: relevance, controversies and challenges. A position paper
2021
Background: Patients with oral lichen planus (OLP) have an increased risk of oral cancer. For this reason, OLP is classified as an oral potentially malignant disorder. However, the precise personal (or individual) risk is unknown. Recent meta-analytical studies have reported that dysplastic OLP may transform to cancer in around 6% of cases, while the rate of transformation is lower (<1.5%) in non-dysplastic cases. The presence of epithelial dysplasia has emerged as the most powerful indicator for assessing cancer risk in oral potentially malignant disorders in routine practice. However, the general acceptance of epithelial dysplasia as an accompanying histologic feature in OLP is subject to…
High-NaCl perception in drosophila melanogaster
2014
Salt is a fundamental nutrient that is required for many physiological processes, including electrolyte homeostasis and neuronal activity. In mammals and Drosophila, the detection of NaCl induces two different behaviors: low-salt concentrations provide an attractive stimulus, whereas high-salt concentrations are avoided. We identified the gene called serrano (sano) as being expressed in the sensory organs of Drosophila larvae. A transgenic reporter line showed that sano was coexpressed with Gr66a in a subset of gustatory neurons in the terminal organ of third-instar larvae. The disruption of sano gene expression in gustatory neurons led to the specific loss of high-salt concentration avoida…
Food: Ordinary Practice or Extraordinary Experience?
2021
Food and the practice of cooking hold a privileged place in contemporary aesthetics, as attested by the extensive literature that has been devoted to this topic. Food has been addressed in both Anglo-American and European studies from multiple points of view, including a cognitivist, pragmatist, phenomenological, everyday and somaesthetic perspective. In this essay I will try to identify a path that allows us to hold together these readings through the ordinary-extraordinary dichotomy. First, I shall analyze food through the lens of the extraordinary, taking into consideration some examples in which food is presented as a true work of art in museums or as an exceptional experience in increa…

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…
THE USE OF LACTOBACILLUS PENTOSUS 1MO TO SHORTEN THE DEBITTERING PROCESS TIME OF BLACK TABLE OLIVES (CV. ITRANA AND LECCINO): A PILOT-SCALE APPLICATI…
2006
Fifty lactobacilli isolated from black table olive brines were evaluated for their salt tolerance, resistance to oleuropein and verbascoside, and ability to grow in modified filter-sterilized brines. A strain of Lactobacillus pentosus was selected and used as a starter to ferment, in pilot plant, black olives (Itrana and Leccino cv.) in brines modified for pH, carbohydrate, and growth factor concentrations, at 28 degrees C. The temperature-controlled fermentation of Leccino cv. olives resulted in obtaining ready-to-eat, high-quality table olives in a reduced-time process. HPLC analysis of phenolic compounds from fermented olives showed a decrease of oleuropein, a glucoside secoiridoid respo…
An innovative method to produce green table olives based on "pied de cuve" technology
2015
The technology of “pied de cuve” (PdC) is applied in food process only to produce wines with an enriched community of pro-technological yeasts. PdC promotes the growth of the desirable microbial strains in a small volume of grape must acting as a starter inoculums for higher volumes. The aim of the present work was to investigate the use of partially fermented brines, a technology known as PdC, developed with lactic acid bacteria (LAB) on the microbiological, chemical and sensory characteristics of green fermented table olives during two consecutive campaigns. The experimental plan included two trials based on different PdCs: trial A, PdC obtained with Lactobacillus pentosus OM13; trial B, …
Enological characterization of natural hybrids from Saccharomyces cerevisiae and S. kudriavzevii.
2007
The effect of yeasts on wine flavor response is of primary importance. The genus Saccharomyces, and mainly the species Saccharomyces cerevisiae, is responsible for alcoholic fermentation. Recently, several novel yeast isolates from wines have been described as hybrid yeasts between S. cerevisiae x S. kudriavzevii. We have analyzed their influence on two grape musts (Macabeo and Tempranillo) in fermentations conducted at four different temperatures (14, 18, 22 and 32 degrees C) by studying volatile compound production, sugar assimilation and other characteristics influencing the enological properties of wine caused by the impact of yeast. Hybrid yeasts behave particularly well at 14, 18 and …
Angular roughshark Oxynotus centrina (Squaliformes: Oxynotidae) in captivity feeding exclusively on elasmobranch eggs: an overlooked feeding niche or…
2015
A specimen of angular roughshark Oxynotus centrina has been kept successfully in captivity for the first time. Over a period of 24 months, the specimen preyed exclusively on the contents of elasmobranch egg cases, suggesting a specialized trophic niche.
