The invention relates to a method for preparing a spiral seaweed health drink, belonging to the field of agricultural product processing. The method comprises the following steps: selecting spiral seaweeds, red dates and fresh ginger as raw materials, grinding and removing fishy smell of the spiral seaweeds, soaking in a citric acid solution, blanching and removing fishy smell in boiling water; diluting the spiral seaweeds in water, adding pectinase for performing enzymolysis, and performing enzyme deactivation, thereby obtaining enzymatic hydrolysate of the spiral seaweeds; removing seeds of the red dates, crushing the jujube flesh, adding water, leaching at a high temperature, and filtering, thereby obtaining jujube juice; pulping the fresh ginger, filtering, gelatinizing the filtrate at a high temperature, adding alpha-starch for performing enzymolysis, and performing enzyme deactivation, thereby obtaining ginger juice; equivalently mixing the enzymatic hydrolysate of the spiral seaweeds, the jujube juice and the ginger juice, clarifying by using chitosan, centrifuging, adding white granulated sugar, citric acid and ethyl maltol, bottling, and sterilizing, thereby obtaining the finished product. The preparation process is reasonable, the operation is simple, the raw materials are readily available and reasonable in proportioning, and the production cost is low; and moreover, the prepared spiral seaweed health drink is good in sensory quality, clarified, transparent and unique in taste, does not any fishy smell and has a health effect.
