Measurement Significance: Pectinase is a class of decomposition colloidal enzymes, including primary nutases, pectin esterase, multi-galacturonic acidThe four major categories of enzymes and pectin lyse enzymes are widely used in plant fruit and microorganisms, mainly used in food, wine, environmental, medicine, textile and daily chemical industry.

Measurement principle: pectinase water congestion gum produces galacturonic acid, has a reducing aldehyde group, reacting with DNS reagent, producing red-brown substance, and has a characteristic absorption peak at 540 nm, determining the light absorbance value of 540 nmCalculate gumase activity.

Need instruments, consumables: balance, low temperature centrifuge, visible spectrophotometer / enzyme symbol, trace quantum-based cuvette / 96-well plate, constant temperature water bath.
