In order to differentiate and characterize Chinese Luzhou-flavor liquor according to geog. origins, the volatile flavor compounds were analyzed for forty com. Luzhou-flavor liquor samples from Sichuan, Jiangsu, and Hubei provinces. A total of 113 volatile flavor compounds were quantified; among them, 29 flavor compounds were quantified according to the internal standard method. The differences in flavor composition among different brands of Luzhou-flavor liquor were compared. A data matrix of 64 (flavor components) × 40 (samples) was studied and interpreted using chemometric anal. The research object could be naturally clustered according to geog. origin (brand) based on the hierarchical cluster anal. (HCA), principal component anal. (PCA) and multivariate anal. of variance (MANOVA) methods. A 100% of predication ability was obtained by the application of K-nearest neighbor model (KNN) for study sample classification. The results demonstrate that the abundance of volatile flavor components in liquors combined with appropriate multivariate statistical methods could be used for the division and traceability of liquors from different geog. origins. This study can provide the basis for the identification of liquor authenticity and the traceability of liquor. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Related Products of 2198-61-0).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Related Products of 2198-61-0
