Wang, Zhen published the artcileA new method to predict the content changes of aroma compounds during the aging process of Niulanshan Baijiu using the GM (1,1) gray model, Recommanded Product: Ethyl nonanoate, the main research area is Niulanshan Baijiu aging aroma compound math model.
Niulanshan Baijiu (NLS), a kind of light-flavor Baijiu, is very popular in China. The gray model [GM (1,1)], a math. model, is used to predict the content changes of key odorants in NLS during the aging process. First, the smell experiment of NLS was carried out by gas chromatog.-olfactometry-mass spectrometry (GC-O-MS). Then, 34 aroma compounds in NLS aged four different years were identified and quantitated, calculated the OAVs of these aroma compounds, there were 18 compounds with OAVs >1, which were considered as important aroma compounds in NLS, and finally, the gray prediction was carried out by modeling the content of these compounds The correlations between the predicted values and actual values were as high as 0.9969. This is the first time that GM (1,1) is used in liquor content anal., and the good prediction results show the applicability of GM (1,1) in predicting the content change of compounds during Baijiu aging.
Flavour and Fragrance Journal published new progress about Aromatic compounds Role: FFD (Food or Feed Use), BIOL (Biological Study), USES (Uses). 123-29-5 belongs to class esters-buliding-blocks, name is Ethyl nonanoate, and the molecular formula is C11H22O2, Recommanded Product: Ethyl nonanoate.
