The invention relates to a preparation method of a
kelp health-care drink. The preparation method disclosed by the invention comprises the following steps of: selecting
kelp, red dates and fresh ginger as raw materials, shredding after cleaning and immersing the
kelp in water, and
blanching in boiling water to remove fishy smell after immersing the shredded kelp in a
citric acid solution; stewing at
high pressure to soften and partly remove fishy smell; pulping; carrying out enzymolysis by adding
pectinase after diluting the kelp pulp by adding water, and deactivating
enzyme to obtain kelp enzymatic
hydrolysate; removing the kernels of red dates, crushing red date
flesh, extracting by adding water at high temperature, and filtering to obtain red data juice; pulping the fresh ginger, filtering, carrying out enzymolysis by adding alpha-
amylase after gelatinizing the filtered fluid at high temperature, and deactivating
enzyme to obtain ginger juice; and clarifying by using
chitosan after mixing the kelp enzymatic
hydrolysate, the red date juice with the ginger juice in equal amount, centrifuging, adjusting by adding white granulated
sugar and
citric acid, bottling, and sterilizing to obtain a finished product. The preparation method disclosed by the invention is reasonable in process, simple to operate, easy to obtain raw materials, reasonable to match and low in production cost. The prepared kelp health-care drink is good in sensory quality, clear, bright, unique in taste and free from peculiar smell and fishy smell, and has a health-care effect.
