摘要: Jerusalem artichoke is an inexpensive and readily available non-grain raw material. Jerusalem artichoke contains nearly 20% (w/w) of carbohydrates, which was composed of 70–90% (w/w) of the inulin and not fermentable by Lactobacillus sp..HMF is considered an important intermediate and platform chemical from carbohydrates due to its rich chemistry and potential availability.Direct formation of HMF from polysaccharides, such as inulin, and even the Jerusalem artichoke juice, was tested using the TA-p catalyst. Remarkably, results demonstrating the tantalum compound is effective on reactions of polysaccharides hydrolysis and monosaccharides dehydration. The highest HMF yield is 87%, which was obtained at 150 min using inulin, a polymer of fructose, as the reactant. Compared with fructose as reactant, a longer reaction time (150 min) was needed to achieve the maximum yield.Thus the Jerusalem artichoke juice was used as reactant to produce HMF, and HMF yield could be reached to 50% when Jerusalem artichoke juice hydrolyzed by exoinulinase without other pretreatment.
