In the fruit juice industry, juice in the press process will bring a lot of impurities in pulp, pectin, starch, plant fiber, microorganisms, bacteria, and other impurities. Thus, it’s not easy to produce juice concentrate through traditional methods. Due to high sugar content in fruit juice, microorganisms and bacteria are easy to breed which makes juice fermentation ferment and deteriorate.
High-temperature sterilization will result in product discoloration and loss of flavor. The traditional filtration methods (diatomaceous earth, framed filter) can not completely retain the impurities, can play a temporary clarification. Under the influence of time, temperature, charge,re-flocculation of dissolved impurities form visible matters, resulting in apple juice turbidity and precipitation.
Fruit juice membrane technology is used mainly to clarify the juice by means of ceramic ultrafiltration and microfiltration and to concentrate it by means of nanofiltration and reverse osmosis.Macromolecular impurities such as plant fiber, starch, bacteria and other impurities in fruit juice are completely intercepted to realize the clarification and impurity removal of juice. Cross-flow design is adopted to solve the problem of filter clogging and will greatly improve the efficiency of producing juice concentrate.
