Headspace solid phase microextraction and purge and trap analysis were used for the determination of volatiles in beer. These methods were compared with the analysis of unconcentrated gas phase and li...
A Principal Component Analysis method based on multivariate analysis was used to evaluate the correlation between the fermentable sugar content of dough and its behaviour during fermentation at differ...
Since 1980s, several methods for the determination of lignans in food samples have been developed depending on the types of lignans and foods analysed, but mostly on flaxseed as a reference food. In t...
The effect of heat treatment using different sources of heat on the chemical composition and microbial quality of milk was studied. Raw cow, goat and sheep milk were heated with charcoal, gas and sol...
A mathematical model to predict oxygen, carbon dioxide, and water vapour exchanges in non-perforated and micro-perforated modified atmosphere packaging films has successfully been proposed. The transm...
A theoretical model of the atmosphere within polymeric film and shipping containers was developed and validated by experiments with or without Welsh onion (Allium fistulosum L.). There were three proc...
Instrumental and sensory analyses were carried out on sesame-flavored dressings to identify the odorants affecting their perceived quality. The sampling of the odor-active compounds was performed by s...
In this study, 70 samples of honey and beeswax from different beehives (Eastern and Western Azerbaijan, Ardabil territory, Iran), markets and store shelves of (Tehran, Iran) were collected during 2006...
A method using solid-phase extraction (SPE) and GC-MS was developed for the determination of a series of polar and unstable flavor compounds: reductones, furans and volatile organic acids, in aqueous ...
Polymeric triplex film with SiOx deposit (polyethylene terephthalate/polyethylene terephthalate+ SiOx/polyethylene) was analysed for its gas permeance characteristics. For this purpose the permeance o...
Non-thermal plasma treatment is a promising technology to enhance the shelf-life of fresh or minimaly processed food. An efficient inactivation of microorganisms comes along with a moderate heating of...
In this study, 70 samples of honey and beeswax from different beehives (Eastern and Western Azerbaijan, Ardabil territory, Iran), markets and store shelves of (Tehran, Iran) were collected during 2006...
In the present study, method of solid-phase extraction followed by capillary gas chromatography coupled to mass spectrometry (SPE-GC-MS) was used for quantitative analysis of trace levels of phthalate...
A simple method is described for the determination of cholesterol in milk and milk products. Samples (0.2 g) are saponified in capped tubes with 0.5 M methanolic KOH solution by heating for 15 min at ...
Automatic headspace gas chromatography was used to assay volatile compounds in fermented milks, including diacetyl, which is of particular interest because of its aromatic properties. -Acetolactic aci...
