The aim of the present study was to determine flavor-active compounds responsible for "sulfur" and "bitter" flavors cooked cauliflower potentially implicated in rejection by consumers. Eleven varieties were assessed a trained sensory panel flavor profile determination. Among 13 attributes, differed mainly according their "cauliflower odor note" "bitterness". Various glucosinolates quantified HPLC correlated with bitterness intensity. results showed that neoglucobrassicin sinigrin...
Abstract Growing evidence indicates that the human gut microbiota interacts with xenobiotics, including persistent organic pollutants and foodborne chemicals. The toxicological relevance of microbiota-pollutant interplay is great concern since chemicals may disrupt functions, a potential impairment host homeostasis. Herein we report within batch fermentation systems impact food contaminants (polycyclic aromatic hydrocarbons, polychlorobiphenyls, brominated flame retardants, dioxins,...
Benzo[a]pyrene (B[a]P) is a ubiquitous, persistent, and carcinogenic pollutant that belongs to the large family of polycyclic aromatic hydrocarbons. Population exposure primarily occurs via contaminated food products, which introduces digestive tract. Although metabolism B[a]P by host cells well known, its impacts on human gut microbiota, plays key role in health disease, remain unexplored. We performed an vitro assay using 16S barcoding, metatranscriptomics volatile metabolomics study...
Because of the demand for controlling livestock diets, two methods that characterize DNA plants present in feces were developed. After extraction from fecal samples, a short fragment chloroplastic trnL intron was amplified by PCR using universal primer pair plants. The first method generates signature is electrophoretic migration pattern product. second consists sequencing several hundred fragments product through pyrosequencing. These validated with blind analysis concentrate- and...
The authentication of the conditions animal production, based on analysis meat commercial cuts, is a major challenge both societal and analytical grounds. aim present work was to propose method for extraction volatile compounds from ruminant raw muscles trimmed fat assess by mass spectrometry-based techniques relevance these type feeding offered animals. first step study consisted validating dynamic headspace (DH) that enabled us minimize appearance heat-induced artifacts maximize richness...
The first objective of the present paper was to assess potential both isotopic (18O/16O in milk water) and molecular biomarkers (terpenes, fatty acids, carotenoids, vitamins) color discriminate production zone (lowland or upland areas) from which 49 tanker bulk milks were collected over one year a total 204 farms. water 18O enrichment higher lowland (<500 m altitude) than (>700 altitude), but δ18O values failed systematically at scale because its high variability related sampling period. In...
Authentication of farm animal rearing conditions, especially the type feeding, is a key issue in certification meat quality and products. The purpose this article was to analyze parallel volatile fraction three adipose tissues excised from 16 lambs order authenticate two diets: pasture (n = 8) concentrate 8). On basis growth rate anatomical location, different lamb were analyzed: perirenal fat (PRF), caudal subcutaneous (CSCF), heart (HF). An initial experiment used optimize extraction...
The aim of this work was to determine the relative impact water-soluble compounds on gustatory properties a goat cheese extract (WSE). Using semisynthetic model mixture (MWSE) previously elaborated in physicochemical and accordance with WSE (see part 1, Engel et al. J. Agric. Food Chem. 2000, 48, 4252−4259), omission tests were performed. Among main taste characteristics (salty, sour, bitter), saltiness explained by an additive contribution sodium, potassium, calcium, magnesium cations,...
