Embodiment 1
[0016] A kind of preparation method of spirulina walnut milk is characterized in that comprising the following steps:
[0017] 1) Select and remove impurities: select plump walnut kernels to remove other impurities in the walnut kernels;
[0018] 2) Soaking and decolorization: Soak the walnut kernels in a sodium bicarbonate solution with a mass concentration of 0.5% at 25°C for 4 hours to remove the pigment on the surface of the testa and soften the cell structure, and then rinse with water;
[0019] 3) Refining and separation: add 50% of the quality of walnut kernels to the walnut kernels in step 2) and grind them into a slurry, so that the protein and oil in them can be fully separated out, and pass through a 150-mesh sieve to obtain raw walnuts under the sieve pulp;
[0020] 4) Spirulina extraction: add spirulina powder to an appropriate amount of hot water at 40°C, adjust the pH to 7.5, stir for 10 minutes, filter and separate the filtrate and filter residue, and add the ...
Embodiment 2
[0026] A kind of preparation method of spirulina walnut milk is characterized in that comprising the following steps:
[0027] 1) Select and remove impurities: select plump walnut kernels to remove other impurities in the walnut kernels;
[0028] 2) Soaking and decolorization: Soak the walnut kernels in a sodium bicarbonate solution with a mass concentration of 0.5% at 35°C for 1 hour to remove the pigment on the surface of the testa and soften the cell structure, and then rinse with water;
[0029] 3) Refining and separation: add 70% drinking water to the walnut kernel in step 2), and grind it into a slurry, so that the protein and oil in it can be fully separated out, and pass through a 200-mesh sieve to obtain raw walnut under the sieve pulp;
[0030] 4) Extraction of spirulina: add spirulina powder to an appropriate amount of hot water at 45°C, adjust the pH value to 8.0, stir for 20 minutes, filter and separate the filtrate and filter residue, and add the filter residue ...
Embodiment 3
[0036] A kind of preparation method of spirulina walnut milk is characterized in that comprising the following steps:
[0037] 1) Select and remove impurities: select plump walnut kernels to remove other impurities in the walnut kernels;
[0038] 2) Soaking and decolorization: Soak the walnut kernels in a sodium bicarbonate solution with a mass concentration of 0.5% at 30°C for 3 hours to remove the pigment on the surface of the testa and soften the cell structure, and then rinse with water;
[0039] 3) Refining and separation: Add 60% of the quality of walnut kernels to the walnut kernels in step 2) and grind them into a slurry, so that the protein and oil in them can be fully separated out, and pass through a 180-mesh sieve to obtain raw walnuts under the sieve pulp;
[0040] 4) Extraction of spirulina: add spirulina powder to an appropriate amount of hot water at 42°C, adjust the pH value to 7.8, stir for 15 minutes, filter and separate the filtrate and filter residue, and...
