Polygonum multiflorum, a traditional Chinese medicinal herb, is widely used in liver and liver nourishing. Recent years, drug regulatory departments reported that Polygonum multiflorum caused serious adverse reaction in clinic, especially liver injury. In this study, we detected the changes in rat serum and liver tissue metabolites through gas chromatography-mass spectrometry (GC-MS). Mass spec...

Triggered by the strong antimicrobial activities of menthol and various fatty acids, eutectic mixtures based on components are developed, producing new solvents that have possibilities to become a antibiotic. This study aims provide an insight into deep (DESs) developed. Menthol-based DES combined with namely propionic acid, butanoic hexanoic octanoic decanoic levulinic were successfully obtain...

Alimet (Novus Inter., Inc., St. Louis, MO) feed supplement (an 88% aqueous solution of 2-hydroxy-4-(methylthio) butanoic acid; HMB) is a source of L-Met commonly used in nonruminants and ruminants. The absorption of HMB across ovine omasal and ruminal epithelia was evaluated in this study. Ruminal and omasal epithelia were collected from eight lambs (BW = 67.6 kg +/- 9.1) and mounted in parabio...

To determine the odor-active compounds in Cheddar cheeses with different ripening times (6, 10, and 14 mo), 39 potent odorants of were identified a flavor dilution factor range between 1 512 by aroma extract analysis. further their contribution to overall profile cheeses, odor activity values 38 factors ?1 calculated. A cheese matrix was developed concentrations thresholds these key compounds. ...

Each cheese type has a unique flavor. A variety of compounds various concentrations and different chemical classes contribute to this In the present study, effect processing techniques (ultrasonication (US), high pressure (HPP), microwave (MW)) on flavors sensory properties milk was investigated. Samples treated untreated were analyzed for volatile (including aldehydes, ketones, alcohols, fatty...

Jasmonic acid is a plant hormone that can be produced by the fungus Lasiodiplodia theobromae via submerged fermentation. From a biotechnological perspective jasmonic acid is a valuable feedstock as its derivatives serve as important ingredients in different cosmetic products and in the future it may be used for pharmaceutical applications. The objective of this work was to improve the productio...

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...

The formation of organic acids during photooxidation of 1,3,5-trimethylbenzene (TMB) in the presence of NOx was investigated with an online ion chromatography (IC) instrument coupled to a mass spectrometer (MS) at the Paul Scherrer Institute’s smog chamber. Gas and aerosol phase were both sampled. Molecular formulas were attributed to 12 compounds with the help of high-resolution MS data from f...
