Pectin is a natural macromolecular substance composed of galactose uronic acid. It can be made from the peel or pomace of pomelo, lemon, citrus, apple and other fruits, as well as other suitable edible plants. It is mainly used in the food industry as a gelling agent, thickener and stabilizer, with gelling, emulsifying and stabilizing functions. In addition, pectin is also an indispensable auxiliary material in the pharmaceutical industry. It can reduce blood sugar, blood fat, cholesterol, blood vessels, diabetes, hypertension, constipation, and lead poisoning. How to better extract pectin and improve its quality? It has always been a concern in the industry.

The commonly used refining method in pectin production is alcohol precipitation, and the commonly used concentration methods are multi effect concentration, vacuum concentration under reduced pressure, etc. In traditional production processes, due to the large amount of extracted liquid, a large amount of steam needs to be consumed during the concentration process, resulting in high production costs for enterprises. Meanwhile, due to the absence of impurity removal during the thermal concentration process, it can lead to an increase in impurities, especially small molecule impurities and inorganic salts, in the extraction solution, thereby affecting the quality of the product. During the alcohol precipitation process, due to the presence of a large amount of impurities in the extraction solution, the content of impurities in ethanol is high, resulting in significant heat recovery losses.

Using membrane separation technology to extract pectin, there is no need for heating during the treatment process, effectively preventing the destruction of the activity of thermosensitive substances. It is a pure physical process without phase change and alcohol precipitation. On the basis of saving production costs, it makes the composition of pectin products closer to natural quality, green and environmentally friendly, fully meeting high-end needs such as product exports. Compared with vacuum concentration, membrane separation technology has the advantages of low energy consumption, strong selectivity, and the ability to remove small molecule substances such as pigments from pectin extract, improving the quality of pectin, making it more economical and reliable than traditional methods.
