Mushrooms from different varieties and manufacturing methods show different flavor profiles. In order to understand the sensory attributes and aroma compounds of boletus, the discrepancy of aroma profile in four varieties of boletus was determined using gas chromatog.-olfactometry combined with sensory anal. and partial least squares regression anal. (PLSR). Sensory anal. revealed that Boletus Edulis had potent roasted and buttery attributes, Boletus Aereu exhibited woody note and Boletus Auripes Pk presented powerful floral and smoky aromas, while Boletus Rubellus Krombh showed weakness in five sensory attributes. The quant. anal. revealed that the dominant volatiles in boletus samples were esters, aldehydes, acids, alcs., pyrazines, ketones and phenols. A total of 42 potent aroma compounds (OAVs > 1) were determined by aroma extract dilution anal. and quant. anal. 1-Octen-3-ol and 2,5-dimethylpyrazine were the potent aroma compounds among four boletus samples. In addition, the key aroma compounds were 3-(methylthio)propionaldehyde and 2,6-dimethylpyrazine in Boletus edulis. Isovaleric acid, 2,6-dimethylpyrazine, benzeneacetaldehyde and (E)-2-octenal were the key aroma compounds in Boletus aereu. In Boletus auripes Pk, isovaleric acid, 3-ethylphenol and 2,6-dimethylpyrazine were the key aroma compounds, while 3-methylvaleric acid, isovaleric acid and 2,3-dimethylpyrazine significantly contributed to the aroma of boletus rubellus Krombh. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Category: esters-buliding-blocks).
Isopentyl hexanoate (cas: 2198-61-0) 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. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Category: esters-buliding-blocks
