This research evaluated the effect of saline conditions on fruit yield, fatty acids, and essential oils compositions and phenolics content of black cumin (Nigella sativa). This plant is one of the most commonly found aro...
The correlation of nonvolatile composition in wines with quality perception is a critical subject in current enological research, and it is far from being clear. Thus, the present work aims at (1) defining the chemical c...
The effects of yeast assimilable nitrogen (YAN) supplementation on Shiraz volatile composition and sensory properties have been investigated. A low VAN Shiraz must (VAN 100 mg/L) was supplemented with nitrogen in the for...
The volatile profile of sparkling wine is influenced by the retention and release of volatile compounds by lees during the aging process. Here we attempted to identify the volatiles that are most retained by lees in agin...
Fruits and vegetables (FAVs) are an important part of the human diet and a major source of biologically active substances such as vitamins and secondary metabolites. The consumption of FAVs remains globally insufficient,...
A sensitive and efficient liquid chromatography mass spectrometry (LC-MS) method was developed and validated for the determination of p-coumaric acid (CA) in rat plasma. After addition of the internal standard (IS) hydro...
The aim of this study was to asses the applicability of LC-MS profiling to authenticate a selected Trappist beer as part of a program on traceability funded by the European Commission. A total of 232 beers were fingerpri...
Glycemic indexes of bread made from mixtures of wheat flour and buckwheat flour are lower than those made from wheat flour. To discuss the mechanism of the buckwheat flour-dependent decrease in glycemic indexes, the form...
The kinetic behavior and protein-expression level of phenylalanine ammonia-lyase (PAL) and polyphenol oxidase (PPO) have been determined in the leaves of the olive tree (Olea europaea L.) of cv. Picual, Verdial, Arbequin...
Chitosan-glucose conjugates were prepared using Maillard reaction chemistry. Water-soluble and acid-soluble chitosan glucose mixtures were heated at pH 4.9 and 6.0 at 98 degrees C. Mixtures at pH 6.0 containing acid-solu...
A sandwich-type immunosensor composed of antigen double target/probe DNA-coated gold nanoparticles (NPs) was developed for the measurement of fluorescence intensity and quantitative analysis of single-stranded DNA based ...
A simple and rapid method for determining polycyclic aromatic hydrocarbons (PAHs) in shrimp is described. For sample preparation, the quick and simple QuEChERS procedure was used. Reverse-phase chromatography using an oc...
This study reports for the first time the metabolic profile of cocoa (Theobroma cacao L.) beans using the H-1 NMR technique applied to polar extracts of fermented cocoa beans. The simultaneous detection and quantificatio...
Amaranth is widely added to food and can cause many adverse health effects when it is excessively consumed. Therefore, the monitoring of amaranth is quite important. Herein, an electrochemical sensor for the sensitive an...
Alkaline phosphatase (ALP), nucleoside phosphorylase (NP), and xanthine oxidase (XOD) were used in a calorimetric method for evaluation of fish freshness based on the K-i value. Two enzyme mixtures, NP-XOD and ALP-NP-XOD...
