What is the role of pectinase in fruit juice production?

1. Pectinase can decompose pectin, disintegrate the cell wall and intercellular layer of plants, and make it easier to extract juice; pectin is decomposed into water-soluble galacturonic acid, which makes the turbid juice clear.

2. The activity of pectinase can be expressed by the volume of filtered juice or the clarity of the juice. Because pectinase decomposes pectin into small molecular substances galacturonic acid, galacturonic acid is soluble in water to make the juice clear, and can pass through filter paper to improve the juice yield, so the volume and clarity of the juice reflect the fruit juice. The ability of glue enzymes to catalyze the breakdown of pectin. The greater the activity of pectinase, the greater the volume of filtered juice and the higher the clarity of the juice.
