Application of 105-21-5, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 105-21-5, Name is Gamma-heptalactone, molecular formula is C7H12O2. In a Article，once mentioned of 105-21-5
In this work, the morphological and chemical properties of Chardonnay and Gewuerztraminer aromatic grapes (northern Spain) have been studied with the aim to assess their response to chamber-drying under controlled conditions and compare it with that of Pedro Ximenez grapes (southern Spain). Morphological characteristics, such as weight, size and roundness, and other of the skin such as thickness, enabled discrimination of the two types of grapes varieties. Changes in browning index, colour, antioxidant activity, aroma compounds determined by GC-MS and flavan-3-ols and flavonols concentrations determined by HPLC-DAD were studied during drying. Based on the results, Chardonnay and Gewuerztraminer grapes contained increased amounts of flavan-3-ol derivatives, which are the greatest contributors to polymerization and condensation reactions. Also, their smaller size resulted in faster drying and leads to sugary musts that were lighter-coloured, less brown and more aromatic than Pedro Ximenez grapes.
