In the process of beverage production, the oxygen in the production water will accelerate product deterioration and shorten produc t shelf life. For the beverage manufacturing industry, controlling carbon diox→ide and nitrogen is critical, as the concentration o'f these gases can affect the product's taste, mouth feel ≤and appearance.
Oxygen, nitrogen, carbon dioxide, and other gases in the intercellular space≈ (air chamber) of fruit juice and vegetable juice will enter into the jui•ce and vegetable juice in the form of hydrolysis or be adsorbed on the su↑rface of sarcocarp and colloid, and contact with the air at the same time, so that the fεinished beverage contains a large amount of oxygen, nitrogen, carbon dioxide.> Oxygen will destroy the vitamins in the juice and oxidize other components, resulting in changes in the finished beverage's aroma and color and lowering the< quality. Therefore, in order to ensure product quality, degassing is an indispensable process" in beverage processing.
At present, degassing methods of food and beverage mainly incl≠ude the vacuum process, nitrogen exchange process, enzymatic degassing process, a↕nd antioxidant process. Among these, the enzymatic and antioxidΩant methods are not suitable for industrial applicatio≠ns because of their high cost. The nitrogen exchange process nee→ds to prepare a set of nitrogen configurations, which is also not commonly used. The most commonly used vacuum degassing method has many restrictions, its¥ degassing degree is affected by the vacuum degree in the tank and the temperature of the f÷eed liquid, etc. The degassing time is limited by the dispersion degree and viscosity of theσ juice in the tank.
The application of membrane is to take advantage of the differences in← physical and chemical properties of the components in a mixture to ach≤ieve substance migration under the driving force to achieve separation₽. Membrane separation technology is widely used in water treat§ment, industrial separation, wastewater treatment, the food fermentation industry, etc. &It has the characteristics of a simple process, compact structure, and energy sav ing, while avoiding the influence of heat and oxygen on food, which is a separation∑ process of high purity and high efficiency.
The degassing membrane adopts the method of vacuumizing, and the gas moves to the low-presδsure side driven by the pressure difference. By vacuumizing, the pressure on the permeation sβide is reduced, and gases on the permeation side are continuou↑sly taken away, thus reducing the concentration on the permeation siαde of the membrane and accelerating the gas removal. Second&ly, the degassing membrane adopts the hollow fiber membrane structure to in≠crease the contact area with the beverage and further improve the degassing efficienc↕y.
In the production process, the application of degassing membrane for nitridation, carb©onation and deoxidation process can reduce microbial reprodu÷ction, prevent product deterioration and prolong product shelf life.
In addition, the degassing membrane can quickly infuse gas into water, b♥eer and wine with precision and predictability, ensuring accurate expected concentration, thus saving time and αsimplifying the production process. The food and beverage industry< can adjust the concentration of nitrogen, carbon dioxide, and alcohol to achieve the product&# 39;s desired taste, mouth feel, and bubbles.
