Milk concentration is a vital process in the dairy industry, which is crucial for extending product shelf life, reducing costs, and producing high-value products. Traditional thermal evaporation methods have drawbacks such as nutrient loss and high energy consumption, while membrane technology has become a preferred alternative due to its low energy consumption, high separation efficiency, and excellent nutrient retention. This paper elaborates on the role of membrane technology in milk concentration, focusing on the application of three core membrane technologies (ultrafiltration, reverse osmosis, and nanofiltration), and analyzes their advantages in nutrient retention, product quality improvement, and green production.
Membrane separation technology is applied in fruit wine processing to realize clarification, impurity removal and sterilization at normal temperature. It effectively intercepts pectin, protein, yeast residues and colloidal particles, while well retaining original flavor, aroma and nutrients of fruit wine. The technology solves turbidity, precipitation and short shelf life problems, features no chemical addition and low-temperature treatment, optimizes production process, improves product stability, and is widely used in industrial refining of various fermented fruit wines.
With the increasing demand of consumers for the quality of juice beverages, membrane separation technology has become a research focus in the field of juice clarification. This paper first points out the problems existing in the traditional juice clarification process and conventional methods, then introduces the working principle of membrane separation technology and its application effect in juice clarification, and takes a well-known juice enterprise as an example to verify its practical value. In addition, the advantages of membrane separation technology such as high efficiency, environmental protection and energy saving are analyzed, which conforms to the concept of green production. Finally, it is pointed out that membrane separation technology has broad development prospects in the juice beverage industry, which is expected to promote the technological upgrading of the industry and provide consumers with higher quality juice products.
