Example Embodiment
[0028] Example 1
[0029] The rice antioxidant peptide microcapsules of this embodiment are composed of a core material and a wall material. The core material is a rice antioxidant peptide. The wall material is divided into an inner wall material and an outer wall material. The inner wall material is porous starch and the outer wall material is seaweed. Sodium; the mass ratio of the inner wall material to the core material is 4, and the mass ratio of the outer wall material to the core material is 3.43.
[0030] The preparation method of rice antioxidant peptide microcapsules is as follows:
[0031] (1) Weigh 28 g of porous starch, add 180 mL of distilled water, stir evenly, then add 7 g of rice antioxidant peptide, and shake and absorb at 30°C for 60 min.
[0032] (2) Weigh 24 g of sodium alginate, add 1420 mL of distilled water at 50°C, and stir until completely dissolved.
[0033] (3) Add the solution obtained in step (2) to the solution obtained in step (1), and stir to obtain a mi...
