Production process of walnut milk beverage:

Walnut kernels → selection → rinsing → soaking → peeling → color protection → grinding → filtering → blending → pre homogenization → vacuum deodorization → homogenization → filling → sterilization → cooling → inspection → finished product

Steps for making walnut milk beverage:

1. Choose rinsing: Choose insect free No mold growth Fresh walnut kernels that do not spill oil should be rinsed with clean water to remove foreign substances such as mud, sand, and residual shells.
2. Soaking: Soak the walnut kernels in clean water to make them absorb water and expand, soften the tissue, and facilitate peeling Grinding and extraction of nutrients. When soaking, the ratio of walnut kernels to water is about 1:2, and the soaking time is 4-5 hours, because later color protection treatment requires soaking for 3-4 hours.
3. Peeling: Boil walnut kernels in a 3% NaOH solution for 3-5 minutes, then rinse with high-pressure water to remove the seed coat.
4. Color protection: Soak the peeled walnut kernels in a mixture of 0.5% NaCl and 0.02% Na SO3 solution for 3-4 hours, perform color protection and bleaching treatment, and then rinse twice with clean water.
5. Grinding: Using a grinding wheel grinder, the method of hot water grinding at 85 ℃ or above is adopted to passivate lipoxygenase. The ratio of water to walnut kernels is 7:1.
6. Filtration: Use a 200 mesh centrifuge to separate the pulp and residue. To improve protein yield, the residue can be soaked and extracted with hot water, and the slurry can be used as water for the next grinding.
7. Preparation: Mix white sugar Emulsifier. Dissolve thickeners, etc Filter, mix with walnut slurry according to the formula ratio, and stir evenly. Soft water with a hardness of less than 4 degrees should be used for mixing water to prevent protein aggregation caused by metal ions Precipitation phenomenon.

8. Pre homogenization: Use colloid grinding once, which is called pre homogenization, to thoroughly mix and refine the material liquid for degassing, deodorization, and high-pressure homogenization.
9. Vacuum deodorization: The feed liquid is deodorized in a vacuum deodorization tank under a vacuum degree of 20-30 kPa. It also plays a role in degassing. And quickly cool the liquid to below 85 ℃.
10. Homogenization: Use a high-pressure homogenizer to homogenize the liquid twice, with a homogenization pressure of 40 MPa and a liquid temperature of around 75 ℃.
11. Filling Capping: Fill while hot with a filling machine. For future observation convenience, this experiment will be conducted in glass bottles and sealed with a crown roller cap.
12. Sterilization: Use a sterilization formula of 10-15 minutes/121 ℃ in a high-pressure sterilization pot for wet heat sterilization.
13. Finished product storage: Bottled beverages that have been sterilized and cooled should be labeled and stored at room temperature.
