What is the function of pectinase enzyme?
Pectinase enzymes are used for extracting juice from purée. This is done when the enzyme pectinase breaks down the substrate pectin and the juice is extracted. The enzyme pectinase lowers the activation energy needed for the juice to be produced and catalyzes the reaction.
How does pectinase work on pectin?
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].
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 does pectinase do in plants?
Pectinase, also called polygalacturonase, is a naturally occurring enzyme that breaks down pectin, which is a substance found in the cell walls of certain types of plants and fruits.
How quickly does pectinase work?
The peak effectiveness can be achieved within 3 to 6 months but it may certainly last longer than that with slowly diminishing effectiveness. Cool storage will maximize the shelf-life and warm storage will shorten it. Also, please note that other factors can inhibit the pectic enzyme such as sulfites or wine acidity.
How Much Does pectinase cost?

When was pectinase invented?
The first commercial application of pectinases was reported in 1930 by Kertesz for the clarification of apple juice.
What is Pectolase used for in winemaking?
Pectolase (Pectolytic Enzyme) is used to break down pectin in wine must allowing pulp fermentation fruit wines to clear. Pectolase also increases the yield of juice by breaking down the cell walls in fruit pulp, resulting in an increased flavour to your wine.
How much is Pectolase per gallon?
The typical dosage for pectolase is 1tsp per gallon added directly to the wine “must” and stirred thoroughly before fermentation. If you forget to add it before fermentation you can add pectic enzyme later but you will have less juice extracted from the fruit.
What is the structure of pectinase?
The pectinase consists of a large right-handed cylinder which is made by folding of a single domain of parallel β-strands and the domain fold is called as parallel β-helix The cylindrical center consists of 7-9 helical turns and at each turn of helix, a unique arrangement of three parallel β-strands is present which …
Is pectic enzyme the same as Pectolase?
If you are making a fruit/vegetable wine or a beer with a lot of fruit in then you are introducing pectin to a liquid. Fortunately, it is easy to reduce the amount of pectin in your wine or beer using a pectic enzyme which is also referred to as pectolase.
What are pectin and pectate lyases?
Pectate lyases are produced by many bacteria, where they are the largest group of pectinolytic enzymes and are directly involved in plant pathogenicity. They are also reported from fungi (Dixit et al., 2004 ). Pectin lyases are mainly reported from micro-organisms but also from plants and animals ( Whitaker, 1990 ).
How are pectinase enzymes similar at the sequence level?
The sequence level similarities among different groups of pectinase enzymes, viz. pectin lyase, pectate lyase, polygalacturonase, and pectin esterase, were also analyzed by subjecting a single protein sequence from each group with common source organism to tree construction.
Where do pectate lyase genes come from?
Pectate lyase-like genes have been isolated from a wide range of plant tissues including germinating seeds, pollen, cell cultures, and ripening fruits.
What is the application of pectinase in biotechnology?
Biotechnology applications. Pectin lyases are the only known pectinases capable of degrading highly esterified pectins (like those found in fruits) into small molecules via β-elimination mechanism without producing methanol (which is toxic), in contrast with the combination of PG and PE, which are normally found in commercial products.
