Description

A method for preparing a nutrient beverage and a mixing and shearing device Technical Field

[0001] This invention relates to the field of beverage production technology, and in particular to a method for preparing a nutrient beverage and a mixing and shearing device. Background Technology

[0002] Existing nutritional beverages primarily function to enhance muscle power or endurance, and for taste, as illustrated in patents CN101816444A and CN105410548B. However, while these beverages contain vitamins, proteins, and other nutrients, they neglect the solubility and stability of these nutrients. Nutritional beverages typically require storage in a cool, dark place and are not suitable for long-term storage, as high temperatures or prolonged storage can cause nutrients to precipitate, decompose, or even denature. This can lead to sedimentation, affecting taste, shelf life, and the effective content of nutrients. Therefore, a method for preparing nutritional beverages with stable nutrient dissolution and resistance to spoilage, along with a mixing and shearing device, is needed. Summary of the Invention

[0135] By comparing the components of the upper and lower solutions in Examples 1 to 5 and the comparative examples, it can be seen that the mixed nutrient beverage components obtained by the mixing method of the internal aqueous phase W1, oil phase O and external aqueous phase W2 in this application are more stable, less prone to sedimentation, and the nutrients are more evenly dissolved and distributed. By comparing the content of the upper and lower solutions in Examples 1 to 5 and the comparative examples with the content of the added components in each example, it can be seen that the nutrient preparation method used in this application can make the nutrients dissolve more thoroughly and less prone to loss.
