4.What Is the Protein Liquid Supplements Manufacturing Process?

Protein liquid supplements have similarities with ordinary liquid production processes, but some steps are still different.

Preparingraw materials

Selecting whey protein from high-quality milk sources as raw materials to ensure purity, freshness, and pollution-free properties. As you can know, liquids cannot do without water, so it is necessary to purify the raw water.

Mixing

Mixing protein raw materials with other ingredients, such as sugar, essence, vitamins, minerals, etc. During the mixing process, attention should be paid to hygiene to avoid other impurities from entering and affecting the subsequent processing of the product.

Homogenization

By physical means, large particles in liquid materials are broken down into small particles and evenly dispersed in the medium. After homogenization, the fat particles in protein are refined, avoiding the problem of fat floating up and making the texture of protein more delicate.

Filling
