The sugar, salts and enzymes contained in pineapples have a diuretic effect, and appropriate consumption is beneficial to patients with nephritis and hypertension. In recent years, the pineapple juice market has a broad prospect and has been sought after by many investors.
The traditional pineapple juice filtration process results in products of low quality, low purity, and a short shelf life. Moreover, the equipment has low work efficiency, high operating costs, and it is difficult to achieve clean production. The traditional concentration process of pineapple juice mostly adopts evaporation concentration technology. Under high-temperature conditions, first of all, a large amount of flavor substances in the product are lost, and the taste and color deteriorate, and a large amount of bioactive substances and nutrients are lost, making it difficult to maintain the original flavor and taste of the pineapple juice. Secondly, the production cycle is long, the energy consumption is high, and the cost is high.
With years of practical experience in serving fruit and vegetable juice production enterprises, DOUPU Company is well aware of the problems in the filtration and concentration processes of pineapple juice. By applying its own membrane filtration and concentration technology combined with years of industry experience, it can achieve clarification in one step, inhibit browning, eliminate traditional processes such as pectin hydrolysis, gelatin addition, and deep filtration, reduce the amount of enzymes used, and avoid the troublesome treatment of diatomite waste and clarification precipitates. At the same time, membrane filtration cold sterilization replaces pasteurization. Bacteria in the pineapple juice can be removed without heating, and there will be no heating odor, browning and caramelization reactions. The power cost of the concentration process is only about 1/4 to 1/8 of that of the evaporation method. Moreover, heat-sensitive substances such as vitamins, pigments, and aromatic components can be retained, the color, aroma and taste are pure, and the nutrients will not be damaged, which can largely maintain the original flavor of the pineapple juice, and the comprehensive cost is low.
The production process of membrane clarification, filtration and concentration of pineapple juice:
Pineapple juice pretreatment → Centrifugation → Membrane filtration → Clear juice → Membrane concentration → Sterilization → Storage
The advantages of the membrane filtration and concentration technology for pineapple juice:
Advanced membrane separation technology can thoroughly separate macromolecular impurities invisible to the naked eye and achieve high-fold concentration of the juice.
The feed liquid operates in a cross-flow mode. Without adding filter aids, the problem of pollution and blockage can be solved.
The pure physical operation process at room temperature has no chemical reactions, and will not damage heat-sensitive components or affect the overall flavor.
Advanced modular design makes it convenient to replace the filter materials, and the operation is simple.
An online regeneration cleaning and sewage discharge device is designed, which reduces the labor intensity and production cost and improves the production efficiency.
The membrane elements are imported foreign filter membranes, with various qualifications, long service life and safety.
Hygienic grade materials are selected, which comply with GMP certification.
