Yang, Menglu published the artcileCharacterization of the flavor in traditional Pixian Doubanjiang by polyphasic quantitative detection technology, Application of 5-Methyl-2-phenylhex-2-enal, the main research area is pixian doubanjiang specific flavor taste indicator polyphasic measure technol; Non-volatiles and volatile substances; PLS-DA; Pixian Doubanjiang; Polyphasic measure technology; Specific flavor and taste indicator.
In the present research, four different samples were investigated by multiple analyzing technol. to reveal the common unique flavor and taste of traditional Pixian Doubanjiang (PXDBJ). These samples were manufactured by inheritor according to the intangible skills and ripened for two years in different enterprises. Citric acid, malic acid, Glu and Asp were the dominant non-volatiles, the proportion of both organic acids ranged from 54.78% to 65.61%, while that of both free amino acids ranged from 22.49% to 29.39%. Et palmitate, Et laurate, γ-cis-himachalane, (+)-valencene and β-ionone were identified as typical volatile constituents by three kinds of GC techniques combined with three pretreatment approaches. These results suggested that these five volatiles and the proportion of four non-volatiles could be used as indicators of flavor and taste to discriminate with other types of traditional fermented soy pastes (miso, dajiang, gochujiang, etc), and were also proofed by sensory evaluation. It laid a vital foundation for revealing the contribution of the traditional skill to unique quality of PXDBJ and the correlation between microbial community diversity and their metabolic regulation.
Food Research International published new progress about Amino acids Role: BSU (Biological Study, Unclassified), BIOL (Biological Study). 21834-92-4 belongs to class isoquinoline, name is 5-Methyl-2-phenylhex-2-enal, and the molecular formula is C13H16O, Application of 5-Methyl-2-phenylhex-2-enal.
