The cell wall of a fruit (apple) contains pectin (found in the middle lamella). Small amounts of Pectinase form in the apple when ripening. Adding more Pectinase can speed up the process of breaking down the pectin molecules in the cell wall therefore releasing more juice.

Do apples contain pectinase?

The cell wall of a fruit (apple) contains pectin (found in the middle lamella). Small amounts of Pectinase form in the apple when ripening. Adding more Pectinase can speed up the process of breaking down the pectin molecules in the cell wall therefore releasing more juice.

What does pectinase do to fruit?

As a plant matures, the enzyme Pectinase breaks down the Pectin, causing fruit to soften. Pectinase is used commercially to hasten the breakdown of fruits in order to extract more juice with more efficiency, reducing cost and waste.

What enzyme produces clear apple juice?

The primary enzymes used in apple juice production are pectinases. A blend of pectin methylesterase and endo-polygalacturonase can increase juice yield during the maceration process. The enzymes reduce stickiness and viscosity without impacting pressability.

Is pectinase harmful to humans?

Pectinase is a useful digestive aid because pectin is a significant component in the human diet. In addition to natural dietary sources such as fruits and vegetables, pectin is used as a thickener and gelling agent in many prepared foods such as jellies and jams.

Why is pectinase produced in apple juice?

Pectinase enzyme removes the soluble pectin from the juice and amylases are used to remove the starch from the juice that causes the unwanted haze in the juice and also is responsible for the gel formation in the juice during storage.

How does pectinase work in apple juice?

Pectinase is an enzyme that catalyzes the breakdown of pectin, a component of the cell wall in fruits such as apples and oranges. Pectinase is used commercially to aid in extracting juice from fruit. By enzymatically breaking down the cell wall, pectinase releases the juice from within the cells.

Is pectinase edible?

During the ripening process, plants generally use pectinase to hydrolyze (break down) the pectin in and between the cell walls, making the cell walls weaker, and therefore edible.

How do you dispose of pectinase?

This product, if unaltered by use, may be disposed of by treatment at a permitted facility or as advised by your local hazardous waste regulatory authority. Residue from fires extinguished with this material may be hazardous.

Why is pectinase used in juice production?

Pectinases are widely used in fruit juice industry for the improvement of the quality of extracted juice. The enzyme enhances the process yield and accelerates the clarification of extracted juice (Saxena et al. 2014; Shah et al. 2015).
