General description

4-羟基-2,5-二甲基-3(2H)-呋喃酮(HDMF,DMHF)是一种焦糖样气味化合物,在基于戊糖的Maillard反应系统中通过GC-MS和GCMS/MS鉴定。通过动态方法研究了DMHF在大气压为0.10 MPa时在283.15 K至313.15 K温度范围内在六种不同溶剂中的溶解度数据。据报道,DMHF对映体通过毛细管电泳法进行分离。商业上它是由L-鼠李糖合成的。通过香气提取物稀释分析(AEDA),DMHF已被鉴定为泰国优质鱼酱样品中的酸性增香剂。它被确定为小麦酒′糟(DG)中的关键香气化合物。据报道,它是草莓中的主要风味化合物,并且已经报道了其生物合成。HDMF存在于菠萝、草莓和葡萄等各种水果中,也存在于牛肉肉汤、炒咖啡、面包皮、烤牛肉、烤芝麻和炖牛肉中。

The selective chemical formation of 4-hydroxy-2,5-dimethyl-3[2H]-furanone (HDF) from D-fructose 1,6-diphosphate in the presence of reduced nicotinamide-adenine-dinucleotides (NAD(P)H) was investigated by means of HPLC-DAD and HPLC-UV-MS/MS. The temperature optimum for HDF formation was 30 degrees C, whereas the pH value (pH

The limited use of distiller's grains (DG) in the food industry depends occasionally on the characteristic odor of DG. For a better understanding of this typical odor, a sensory evaluation was performed first. The impressions seasoninglike, roasty/breadlike, and malty/caramellike were
