4-羟基-2（或5）-乙基-5（或2）-甲基-3（2 H）-呋喃酮（HEMF）被认为是由多种酵母通过戊糖-磷酸循环中的中间产物如D-核酮糖-5-磷酸合成的。在本研究中，证明了D-木酮糖5-磷酸，戊糖-磷酸循环的中间体之一，存在于大豆分离蛋白的酶解产物和酱油酱油醪中，在酱油发酵中酵母生长之前。据报道，D-木酮糖5-磷酸是HEMF的前体。
4-Hydroxy-2(or 5)-ethyl-5(or 2)-methyl-3(2H)-furanone (HEMF) has been presumed to be biosynthesized by many kinds of yeast through intermediates, like D-ribulose 5-phosphate, found in the pentose-phosphate cycle. In this study, it was proved that D-xylulose 5-phosphate, one of the intermediates in the pentose-phosphate cycle, was present in both the enzymatic hydrolysates of isolated soybean protein and in shoyu moromi mash before the growth of yeasts in shoyu fermentation. It is also reported that D-xylulose 5-phosphate is the precursor for HEMF.
