Identification of honey origin based on specific chem. markers is important for honey authentication. This study is aimed to differentiate Malaysian stingless bee honey from different entomol. origins (Heterotrigona bakeri, Geniotrigona thoracica and Tetrigona binghami) based on physicochem. properties (pH, moisture content, ash, total soluble solid and elec. conductivity) and volatile compound profiles. The discrimination pattern of 75 honey samples was observed using Principal Component Anal. (PCA), Hierarchical Clustering Anal. (HCA), Partial Least Square-Discriminant Anal. (PLS-DA), and Support Vector Machine (SVM). The profiles of H. bakeri and G. thoracica honey were close to each other, but clearly separated from T. binghami honey, consistent with their phylogenetic relationship. T. binghami honey is marked by significantly higher elec. conductivity, moisture and ash content, and high abundance of 2,6,6-trimethyl-1-cyclohexene-1-carboxaldehyde, 2,6,6-trimethyl-1-cyclohexene-1-acetaldehyde and Et 2-(5-methyl-5-vinyltetrahydrofuran-2-yl)propan-2-yl carbonate. Copaene was proposed as chem. marker for G. thoracica honey. The potential of different parameters that aid in honey authentication was highlighted. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Reference of 112-14-1).
Octyl acetate (cas: 112-14-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Reference of 112-14-1
