How is pectinase used in the food industry?
Pectinases contains groups of enzymes that degrade the pectin substances. In food sector, these enzymes are used for extraction, clarification, and stabilization of fruit juices. They also increase juice yield and involved in coffee, cocoa and tea fermentation and in preparation of jams and jellies.
What does pectinase do to fruit?
Pectinase is an enzyme that catalyzes the breakdown of pectin, a component of the cell wall in fruits such as apples and oranges. By enzymatically breaking down the cell wall, pectinase releases the juice from within the cells. Pectinase is also used for clarifying the extracted juice.
How does pectinase enzyme work?
Pectinase enzyme acts on the pectin and breaks the glycosidic bonds present between the galacturonic acid monomers thereby decreases the water holding capacity of pectin. Hence high yield of juice is obtained [15].
Can you eat pectinase?
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.
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.
Is pectinase harmful?
Inhalation May be harmful if inhaled. May cause respiratory tract irritation. Skin May be harmful if absorbed through skin.
How can I get pectinase naturally?
Pectinolytic enzymes are naturally produced by many organisms like bacteria, fungi, yeasts, insects, nematodes, protozoa and plants. Submerged fermentation and solid state fermentation have been successfully used in pectinase production by fungi and bacteria.
How much pectinase should I use?
Pectinase should be added whilst the fruit is being crushed. It is recommended you add 1 heaped teaspoon of enzyme per gallon (4.5 Litres) of wine to prevent hazes.
When should I add pectic enzyme?
As for winemaking, the optimum time to add pectic enzyme is right after crushing the fruit and before pressing. By breaking down the pectin cells at this stage, you are allowing more juice to release from the fruit’s fiber – a good thing for making wine.
Do humans produce pectinase?
Pectinases have also been used in wine production since the 1960s. The function of pectinase in brewing is twofold, first it helps break down the plant (typically fruit) material and so helps the extraction of flavours from the mash….Pectinase.

Is pectinase the same as pectin?
is that pectin is (carbohydrate) a polysaccharide extracted from the cell walls of plants, especially of fruits; under acidic conditions it forms a gel it is often used in processed foods, especially jellies and jams where it causes thickening (setting) while pectinase is (enzyme) any of various enzymes that break down …
Where is pectinase found naturally?
Pectinases are present in fruits of plants where they play a natural role in the ripening process; but microbial sources are used for large-scale production, due to their ease of multiplication and maintenance, under controlled conditions. Various fungal, bacterial, and yeast strains are used for pectinases production.
What is the optimum pH for pectinase to work?
As with all enzymes, pectinases have an optimum temperature and pH at which they are most active. For example, a commercial pectinase might typically be activated at 45 to 55 °C and work well at a pH of 3.0 to 6.5. Pectinase is commonly used in fruit industries to speed up fruit juice extraction.
What does pectinase mean?
Freebase(0.00 / 0 votes)Rate this definition: Pectinase. Pectinase is an enzyme that breaks down pectin, a polysaccharide found in plant cell walls. Commonly referred to as pectic enzymes, they include pectolyase, pectozyme and polygalacturonase.
What does pectic enzyme do?
The pectic enzyme is a protein that is capable of breaking down the pectin cells into carbohydrates that are less complex – something that does not refract the light and give the juice a cloudy appearance. Essentially, the pectic enzyme causes a chemical change in the juice.
