Methylpyrane anthocyanin preparation method and application of methylpyrane anthocyanin

The invention belongs to the field of wine making, and particularly relates to a methylpyrane anthocyanin preparation method and an application of methylpyrane anthocyanin prepared by the preparation method to the field of aged wine preparation. According to experimental determination, by the preparation method, after one month, the yield of the methylpyrane anthocyanin is relatively improved by 20%-40%. Therefore, synthesis of methylpyrane anthocyanin can be promoted, reaction time is shortened, the synthesis efficiency of the methylpyrane anthocyanin is improved on the whole, and the technical shortcomings of low synthesis speed and low synthesis yield of a methylpyrane anthocyanin synthesis method in the prior art are overcome. 本发明属于酿酒领域，尤其涉及种甲基吡喃花色苷的制备方法及其应用。本发明提供了种甲基吡喃花色苷的制备方法，本发明还提供了上述制备方法得到的甲基吡喃花色苷在陈化酒制备领域的应用。经实验测定可得，通过本发明提供的制备方法，1个月后，与对照相比，本发明甲基吡喃花色苷的产率提高了20％～40％。说明本发明提供的技术方案，可以辅助促进甲基吡喃花色苷的合成，缩短反应时间，提高产率，整体上提高了甲基吡喃花色苷的合成效率，解决了现有技术中，甲基吡喃花色苷的合成方法，主要存在着合成速度慢以及合成产率低的技术缺陷。
