Blueberry juice is rich in vitamins, amino acids and anthocyanins, which can delay the aging of brain nerves, improve memory, and protect eyesight. It is listed as one of the top five healthy foods by the United Nations Food and Agriculture Organization (FAO). Therefore, blueberry juice is favored by consumers, but due to the low filtration accuracy of the traditional plate-and-frame filtration method, it cannot completely retain impurities such as macromolecular protein, pectin, starch, plant fiber and other impurities in the blueberry stock solution, resulting in "secondary precipitation" in the juice. . With the development of membrane separation technology, membrane separation is gradually used in the clarification and filtration of blueberry juice, and has achieved remarkable results. Today, the editor of Bona Bio will introduce the application of membrane separation technology in blueberry juice.
Blueberry juice clarification membrane separation technology process:
Blueberry - fruit selection - washing - crushing and juicing - alcohol fermentation - fruit vinegar fermentation - heating - coarse filtration - centrifugation/plate frame - preparation - membrane filtration - filling - sterilization - finished product
Bona Bio uses the principle of selective screening of polymer membrane materials to completely intercept the above-mentioned macromolecular impurities at the molecular level, and through the cross-flow operation mode, the impurities are not easily blocked on the membrane surface, and the active ingredients pass through the membrane with the filtrate. The surface layer can realize the separation and clarification of blueberry vinegar and also solve the problem of filter blockage.
Advantages of blueberry juice clarification membrane separation technology:
1. Membrane separation is a purely physical process, without phase change, qualitative change, no chemical reaction, no damage to active ingredients, and no change in the taste of juice;
2. Advanced nanotechnology materials can completely separate macromolecular impurities that are invisible to the naked eye, and the filtrate is clear and has high light transmittance.
3. Long service life, good regeneration performance, strong anti-microbial contamination ability, and can maintain high permeation flux and retention rate for a long time;
4. Membrane filtration can replace traditional diatomite filtration equipment and precipitation clarifier, simplifying the process and saving production costs, reducing pollutants, and achieving environmental protection;
5. The automatic PLC design can regenerate cleaning and sewage on-line, reduce labor intensity and realize cleaner production;
6. The membrane system is made of stainless steel 304 or 316L, which is in line with QS certification.
