As a manufacturer of pectin, there are many ways to produce pectin. We usually use metal salting out or organic solvent (ethanol) precipitation method to extract. Next, we will introduce the pectin used in the manufacture apple pectin for apple jam.
Alcohol precipitation method of manufacture apple pectin for apple jam
Alcohol precipitation is a method that is often used and the earliest to realize industrial production. And then the basic principle is to use the characteristic that pectin is insoluble in alcohol solvents. We add a large amount of alcohol to form an alcohol-water mixture in the aqueous solution of pectin to precipitate the pectin. Then, the precipitated pectin block squeeze, wash, dry and crush to obtain the finished product.
Other solvents such as isopropanol can also be used instead of alcohol. The concrete extraction process: raw material pretreatment-acid extraction-filtration-concentration-ethanol precipitation-filtration-low temperature drying-crushing, standardization-finished pectin.
Salting-out method of manufacture apple pectin for apple jam
We currently widely use the multivalent metal salt precipitation method in production. The specific method is: adding a certain amount of MgCl2, CuCl2 or AlCl3 to the pectin solution and then adjusting the pH with ammonia, etc., to form a basic metal salt. This basic metal salt forms a complex with pectin and precipitates out. After desalting, rinsing and drying, we can obtain the finished pectin. The specific process is: apple peel residue-rehydration-enzyme inactivation-rinsing-draining-acid extraction-filtration-salt precipitation-suction filtration-washing-drying-crushing-product. This is the process of manufacture apple pectin for apple jam.
The mixed salting-out method uses a mixed salt of iron and aluminum to precipitate pectin. Moreover, the obtained precipitate has good properties, is easy to separate, and has a lighter color and a higher yield. Therefore, it is a better method of precipitating pectin.
Advantages: Acid extraction is the oldest industrial pectin production method. A more comprehensive review made in 1925. Precipitation pectin with alcohol, traditional and sophisticated, the process is relatively simple. Various conditions are relatively easy to control, no pollution. Therefore, the apple pectin’s manufacture obtained is of good quality and high purity.
The above is a brief introduction to the manufacture apple pectin for apple jam. Thank you for watching this blog.
