Flavor compounds have been shown to interact with packaging materials either by scalping, the movement of flavorings from the food product to the package, or by flavor release, movement of flavorings from the package to the food. Work has elucidated the parameters important for the scalping of flavor compounds to polyolefin packaging materials, but very little work has been conducted examining ...

Lipid oxidation products are primary contributors to whey ingredient off-flavors. The objectives of this study were to evaluate the impact of antioxidant addition in prevention of flavor deterioration of fluid whey and spray-dried whey protein. Cheddar and Mozzarella cheeses were manufactured in triplicate. Fresh whey was collected, pasteurized, and defatted by centrifugal separation. Subsequen...

With the broad applications of two-dimensional transition, metal dichalcogenides in gas sensing prompt us to investigate adsorption and properties bare metal-decorated tungsten disulfide (WS 2 ) interaction with nonanal octanal molecules by using first-principles methods. In this regard, calculations based on density functional theory (DFT) have been employed study detection as well-known breas...

The purpose of the work was to compare quality selected honey available on Polish market, including traditional (rape, lime and meadow marsh honey) non-traditional (lime, buckwheat, honeydew from coniferous honeydew). Parameters such as electrical conductivity, color, pH, acidity, water, hydroxymethylfurfural, total phenols content, ability deactivate ABTS cation radicals were determined. profi...

Indoor surfaces play a key role in indoor chemistry, including modification of oxidant concentrations. This study utilises the INdoor CHEmical Model Python (INCHEM-Py) to investigate impact surface transformations and their on gas-phase chemistry. INCHEM-Py has been developed simulate deposition ozone hydrogen peroxide onto nine six individual respectively typical bedroom, kitchen office for no...

Malodorous compounds induce stress responses, mood changes, an increase of skin conductance, activation the sympathetic nervous system and other physiological it has been suggested that sensing malodors could provide warning danger to health. Furthermore, human body secretes various malodorous as waste products metabolism, including trans-2-nonenal ((E)-2-nonenal), amount which increases with a...

In choice bioassays, Rhopalosiphum padi L. nonviruliferous apterae preferentially locate near volatile organic compounds (VOCs) emitted from Barley yellow dwarf virus (BYDV)-infected wheat plants compared with VOCs from noninfected plants. However, the specific VOCs responsible for R. padi responses are unknown. It is unclear also if R. padi responses to BYDV-infected wheat are caused by arrest...

Native Amine Dehydrogenases (nat-AmDHs) are NAD(P)H-enzymes performing reductive amination, mainly active towards small aliphatic aldehydes and cyclic ketones, due to site volumes limited by the presence of several bulky amino acids. Herein, inspired diversity residues at these positions among family, we report implementation mutations F140A W145A in CfusAmDH their transposition nine other memb...

Dry-cured meat products are considerably popular around the world due to unique flavor. Proteolysis is one of enzymatic reactions from which flavor substances derived, affected by endogenous proteases. The purpose aimed reveal potential relationship between proteases and key in dry-cured pork coppa this paper. dynamic changes activity, free amino acids, volatiles during processing were characte...

Evaluation of dry-cured Iberian ham quality is carried out by means the sense smell experts and a percentage these hams are discarded due to odour defects. However, in cellars cannot be altered sampling because they would devaluated, which makes instrumental analysis difficult. Thus, aim this work assess potential headspace gas chromatography coupled ion mobility spectrometry (HS-GC-IMS) or mas...
