What is pectinase enzyme?
Pectinase is a kind of composite enzymatic system which contains polygalacturonase,cellulase ,hemicellulase and amylase etc. It is extracted from Aspergillus Niger by the deep fermentation methods. It can hydrolyze pectin,cellulose,hemicellulose and starch to monosaccharide and oligosaccharide, and improve nutritional value and filterability of Juice. Also known as pectic enzymes, they are added to livestockfeed to help animals better digest their feed. They are also sold as nutritional supplements for humans to aid digestion.
They can be extracted from fungi such as Aspergillus niger. The fungus produces these enzymes to break down the middle lamella in plants so that it can extract nutrients from the plant tissues and insert fungal hyphae. If pectinase is boiled it is denatured (unfolded) making it harder to connect with the pectin at the active site, and produce as much juice.
Function of pectinase enzyme:
1) Pectinase is added to livestock feed to help the animals better digest their food. This improves the health of their digestive systems and helps them to better digest nutrients;
2) The food and wine-making industries frequently use these enzymes in combination withamylase, which degrades starch, to clarify solutions;
3) Pectinase is also used when fruit is turned into pulp and then extracted to remove its juice because it has been found to improve the yield;
4) Other uses for pectic enzymes in the food industry include softening fruit rinds to making peeling them easier, and to ferment coffee and tea.
