Abstract

The invention relates to a preparation method of dried day lilies. The preparation method comprises the following steps of (1) picking day lilies; (2) pretreating the picked day lilies; (3) cooking the pretreated day lilies; (4) twisting the day lilies treated in the step (3), after twisting is completed, performing sealing at room temperature, and performing static fermentation for 12-18h; and (5) performing drying. According to the preparation method disclosed by the invention, water-soluble glucan and a reduction type glutathione aqueous solution are used for performing pretreatment, and then high-temperature rapid-scalding and cooking are performed, so that technical obstacles are well overcome; the water-soluble glucan can form a layer of a protective film on the surfaces of the day lilies, and can generate substance cross-linking with the histocyte of the day lilies, so that the tenacity of the day lilies in subsequent treatment can be enhanced, the day lilies are not liable to crush when being rolled, and the quality of the day lilies is good; and the reduction type glutathione is also uniformly distributed in the protective film, the reduction type glutathione and the protective film are in synergistic reaction to avoid polyphenol oxidase oxidation, after practice, people find that the reduction type glutathione and the protective film can efficiently prevent the day lilies from changing color during draining and steam rapid-scalding, and the tenacity of the day lilies after rapid-scalding and cooking is still high.
