Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 13325-10-5, Name is 4-Aminobutan-1-ol, SMILES is OCCCCN, belongs to alcohols-buliding-blocks compound. In a document, author is Ni, Hui, introduce the new discover, COA of Formula: C4H11NO.
Enzymatic hydrolysis and auto-isomerization during beta-glucosidase treatment improve the aroma of instant white tea infusion
The aroma changes in instant white tea resulting from beta-glucosidase treatment was investigated by quantitative descriptive analysis (QDA), gas chromatography-mass spectrometry (GC-MS), odour activity value analysis (OAV), aroma reconstruction and omission tests. The grassy, floral and sweet notes increased significantly (P < 0.05), and the roasted note decreased significantly (P < 0.05) upon beta-glucosidase treatment. Quantitative analysis showed that the concentrations of benzaldehyde, benzeneacetaldehyde, (Z)-3-hexen-1-ol, linalool, phenylethyl alcohol, cis-linalool oxide, trans-linalool oxide, hexanol, hotrienol and (E)-2-hexen-1-ol increased significantly (P < 0.05) after treatment; however, (Z)-3-hexen-1-ol isomerized to (E)-2-hexen-1-ol. OAV analysis, aroma reconstruction and the omission test showed that the grassy, floral and sweet notes increased as the (Z)-3-hexen-1-ol, cis/trans-linalool oxide and benzeneacetaldehyde increased, whereas the roasted note declined under the same conditions. The enzymatic hydrolysis of glycosidic precursors and the auto-isomerization of volatile compounds provide new information for understanding how beta-glucosidase treatment improves the aroma of tea products. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13325-10-5 is helpful to your research. COA of Formula: C4H11NO.
