The invention discloses a novel method for preparing embeddings, which comprises the following steps: placing
ferritin solution in a
centrifuge tube, adjusting the pH value with
sodium hydroxide solution to denature, and stirring; taking natural pigments and dissolving them in
ethanol Solution: mix the
polyphenol ethanol solution with the above-mentioned
ferritin solution, stir at
room temperature, adjust the pH value for renaturation, stir in a chromatographic cabinet at 4°C, and dialyze the above-mentioned solution three times to obtain the
ferritin natural
pigment embedding. Then, the ferritin
pigment embedding material and
chitosan were mixed in a certain proportion, stirred, statically prepared, and dialyzed in a chromatographic cabinet at 4°C in the dark to obtain the final product. The final product is a new type of embedding material loaded with natural
pigment molecules by ferritin /
chitosan, which can be used as a new
food additive, can also be used to improve medical
efficacy, and can also be used as a component in
cosmetics, embedding material
Ferritin and natural pigments produced after
decomposition also have certain
biological activity. This product makes full use of the functions of ferritin and natural pigment, and has high practical application and promotion value.
