AI Technical Summary

Technical Problem

In the traditional milk beverage concentration process, there are problems such as loss of heat-sensitive ingredients, low efficiency of introduction of high osmotic pressure additives and high energy consumption, making it difficult to effectively maintain the nutritional ingredients and flavor of milk beverages.

Method used

Using positive osmotic membrane technology, the high osmotic pressure additive solution is used as the driving liquid to transfer the water in the milk beverage to the high osmotic pressure additive solution, and at the same time, the high osmotic pressure additive diffuses into the milk beverage system, achieving the concentration of the milk beverage and the precise addition of functional ingredients.

Benefits of technology

The concentration of milk beverages is completed under low temperature conditions, effectively retaining the nutrients in milk beverages, improving the concentration efficiency, reducing energy consumption, and significantly improving the texture, flavor and functionality of milk beverages.

Abstract

The invention relates to the technical field of dairy product processing and membrane separation, in particular to a membrane concentrated milk beverage and a preparation method thereof. The preparation method comprises the following steps: 1) pretreating the milk beverage; (2) respectively introducing the pretreated milk beverage and the high-osmotic-pressure additive solution into two sides of a forward osmosis device, and respectively obtaining a concentrated milk beverage and a low-concentration draw solution through forward osmosis membrane separation; and (3) homogenizing and post-processing the concentrated milk beverage obtained in the step (2) to obtain the finished milk beverage. And (4) recycling the low-concentration draw solution in the step (2) for reutilization. The method can solve the problems of loss of heat-sensitive components, low introduction efficiency of a high-osmotic-pressure additive, high energy consumption and the like in a traditional milk beverage concentration process, and the overall quality of the milk beverage is remarkably improved.
