Unit operations during production influence the sensory properties of nonfat dry milk (NFDM) and milk protein concentrate (MPC). Off-flavors in dried dairy ingredients decrease consumer acceptance of ingredient applications. Previous work has shown that spray-drying parameters affect physical and sensory properties of whole milk powder and whey protein concentrate. The objective of this study was to determine the effect of inlet temperature and feed solids concentration on the flavor of NFDM and MPC 70% (MPC70). Condensed skim milk (50% solids) and condensed liquid MPC70 (32% solids) were produced using pilot-scale dairy processing equipment. The condensed products were then spray dried at either 160, 210, or 260C inlet temperature and 30, 40, or 50% total solids for NFDM and 12, 22, or 32% for MPC70 in a randomized order. The entire experiment was replicated 3 times. Flavor of the NFDM and MPC70 was evaluated by sensory and instrumental volatile compound analyses. Surface free fat, particle size, and furosine were also analyzed. Both main effects (30, 40, and 50% solids and 160, 210, and 260C inlet temperature) and interactions between solids concentration and inlet temperature were investigated. Interactions were not significant. In general, results were consistent for NFDM and MPC70. Increasing inlet temperature and feed solids concentration increased sweet aromatic flavor and decreased cardboard flavor and associated lipid oxidation products. Increases in furosine with increased inlet temperature and solids concentration indicated increased Maillard reactions during drying. Particle size increased and surface free fat decreased with increasing inlet temperature and solids concentration. These results demonstrate that increasing inlet temperatures and solids concentration during spray drying decrease off-flavor intensities in NFDM and MPC70 even though the heat treatment is greater compared with low temperature and low solids.

The aim of this work was to reliably identify odorous compounds of European seabass (Dicentrarchus labrax) after 1, 4 and 15 days of storage in order to find markers of freshness or spoilage. For this purpose, a dynamic headspace gas chromatography olfactometry device (DH-GC-MS/8O) was used with a panel of eight sniffers for comprehensive detection of odorants. One- and two-dimensional gas chromatography (GC-GC-MS/O) coupled with olfactometry and mass spectrometry gave reliable identification. More than 144 volatile compounds were detected in seabass flesh, of which only 13 proved to be odorant (their biochemical origins are discussed): methane-thiobis, thiophene, toluene + butanoic acid ethyl ester, hexanal, 1-hexanol, 1-octen-3-one, 1-octen-3-ol, dimethyl-trisulfide, octanal, 1-nonen-3-ol, (E)-2-nonenal and 2 unknown compounds. Amongst these compounds, only thiophene, hexanal, 1-octen-3-one, dimethyl-trisulfide, and 1-nonen-3-ol are proposed as markers of seabass quality.

As part of our efforts to identify volatile decomposition products in used frying oils, a series of 4- and 5-oxoaldehydes were synthesized, purified, and characterized by gas chromatography, gas chromatography-mass spectrometry, gas-chromatography-Fourier transform infrared spectrometry, and nuclear magnetic resonance spectrometry.Oxoaldehydes have been proposed as possible precursors of alkylfurans, which have potential anticancer effects.In a model reaction 4-oxononanal was refluxed in hexane for 40 days and only trace amounts of 2-pentylfuran were produced, suggesting that it is not a major precursor of the furan.The volatile constituents of used frying oils obtained from commercial food processors were studied, and 4-oxohexanal, 4-oxooctanal, 4-oxononanal, and 4-oxodecanal were identified.Keywords: Oxoaldehydes; odor threshold; frying oil

Unit operations in nonfat dry milk (NFDM) manufacture influence sensory properties, and consequently, its use and acceptance in ingredient applications. Condensed skim milk may be stored at refrigeration temperatures for extended periods before spray drying due to shipping or lack of drying capacity. Currently, NFDM processors have 2 options for milk concentration up to 30% solids: evaporation (E) or reverse osmosis (RO). The objective of this study was to determine the effect of condensed milk storage and milk concentration method (E vs. RO) on the flavor of NFDM and investigate mechanisms behind flavor differences. For experiment 1, skim milk was pasteurized and concentrated to 30% solids by E or RO and then either stored for 24?h at 4C or concentrated to 50% solids by E and spray dried immediately. To investigate mechanisms behind the results from experiment 1, experiment 2 was constructed. In experiment 2, pasteurized skim milk was subjected to 1 of 4 treatments: control (no E), heated in the evaporator without vacuum, E concentration to 30% solids, or E concentration to 40% solids. The milks were then diluted to the same solids content and evaluated. Volatile compounds were also measured during concentration in the vapor separator of the evaporator. Sensory properties were evaluated by descriptive sensory analysis and instrumental volatile compound analysis was conducted to evaluate volatile compounds. Interaction effects between storage and method of concentration were investigated. In experiment 1, E decreased sweet aromatic flavor and many characteristic milk flavor compounds and increased cardboard and cooked flavors in NFDM compared with RO. Liquid storage increased cardboard flavor and hexanal and octanal and decreased sweet aromatic flavors and vanillin concentration. Results from experiment 2 indicated that the characteristic milk flavors and their associated volatile compounds were removed by the vapor separator in the evaporator due to the heat and vacuum applied during concentration. These results demonstrate that off-flavors are significantly reduced when RO is used in place of E and storage of condensed milk is avoided.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C9H16O2, you can also check out more blogs about3301-94-8

Assessment of Tokaj varietal wines with comprehensive two-dimensional gas chromatography coupled to high resolution mass spectrometry

Botrytised wines produced in Tokaj region belong to a special category of sweet wines described with a pleasant honey-like taste and a distinctive fruit flavour. Specific technological process of wine-making developed on macerating of noble-rotten berries in fermented juice or wine, results in alcoholic beverage indicated with the ‘Protected Designation of Origin’ label. A limited number of publications is devoted to analysis of Tokaj wines or by-products (e.g. individual varietal wines, essencia and must) which directly related to final characteristics of botrytized wine. A combination of two-dimensional gas chromatography connected to high-resolution mass spectrometry (GC ¡Á GC-HRTOFMS) offers enhanced separation and reliable identification of organic compounds presented in complex samples. In our study, this technique was applied to analyse varietal wines of the Tokaj wine region produced from three main grape cultivars (Furmint, Lipovina and Muscat Blanc a Petits Grains). The primary task was reliable separation and identification of low volatility compounds (acetamides, 2H-pyrrole- and 2H-pyran-based heterocyclic compounds and sulphur containing compounds) because of the lack of available information in this area. Thus, it revealed the presence of 1(3H)-isobenzofuranone, ethyl 1H-indole-3-acetate and 2-(methylmercapto)benzothiazole which were not previously detected in wine. Furthermore, trace aroma compounds (terpenoids and lactones) was quantified with modified stir bar sorptive extraction method which provided LOD and LOQ values of 2.3?4.7 ng/L and 7.7?15.8 ng/L, respectively. Linear calibration dependencies with correlation coefficients varying between 0.960 ? 0.996 were obtained.

Volatile component quantification in combination with putative gene expression analysis reveal key players in aroma formation during fruit ripening in Carica papaya cv ?Hong fei?

The purpose of this research was to quantify volatile compound changes during papaya fruit ripening and to identify putative genes that are responsible for aroma synthesis. Volatile compounds at four different stages of fruit ripening were isolated from ?Hong fei? variety by solvent assisted flavor evaporation, then analyzed by gas chromatography-mass spectrometry. In total, 38 different volatile compounds were identified, including terpenes, esters, lactones, ketones, alcohols, aldehydes, volatile acids, S- and N- containing compounds, and volatile phenols. The contents of terpenes, esters, lactones, ketones, volatile acids, and volatile phenols showed general upward trends and reached amximum at half yellow or full ripe stages, meanwhile most alcohols, aldehydes, S- and N-containing compounds showed downward trends with fruit ripening. The putative aroma biosynthesis genes were quantified by RT- qPCR, and the correlation analysis suggested that CpLIS1 and CpP450-2 could be responsible for linalool and linalool oxide biosynthesis, respectively; BITC biosynthesis could be regulated at post-transcriptional, post-translational or enzymatic levels, CpAAT1 and CpACX1 could catalyze the formation of some specific esters or lactones. This study offered important clues for further dissection of the molecular mechanisms underlining aroma synthesis in ?Hong fei? during fruit ripening.

Evolution and status of preparative gas chromatography as a green sample-preparation technique

The present paper reviews recent approaches to preparative capillary gas chromatography (PCGC) covering the period 2010-14. The “green” character of this approach is discussed in relation to the capability to collect chemicals from complex samples, avoiding the consumption of organic solvents that represent a great environmental issue. A discussion is presented regarding critical points in PCGC, mainly related to sample injection, sample capacity, collection system, conditions and sample flushing issues. Following the increasing trend related to the use of multi-dimensional (MD) techniques in recent decades, a section is devoted to the benefits when such an approach is applied in PCGC. One-dimensional and MD applications covering different fields that have appeared in literature since 2010 are described, mainly followed by elucidation steps often performed by nuclear magnetic resonance (NMR), vapour-phase Fourier-transform infrared (FTIR) spectroscopy and mass spectrometric (MS) analyses.
