Lipase is made from an Aspergillus niger through cultivation and extraction technique. Through the targeted compound，it can be used in leatherworking, feed, papermaking, detergent, bioenergy and other industries.
Specifications/ PHYSICAL AND CHEMICAL PROPERTIES
: Normal fermentation odour
: Stable 4-10, optimum 6.5-7.5
: Stable 30-70℃, optimum 55-65℃
1 unit of Lipase equals to the amount of enzyme, which hydrolyzes substance to get 1umol titratable fatty acid in 1 min. at 40℃ and pH7.5.
1 For baking industry
The effect of lipase in the flour product is that it can repair the weak part of the structure of gluten network; improve the stability and holding capacity of the dough; make the bread core white and luster; make steamed bread white and shiny. Recommended dosage: 0.01-0.05kg/t flour（Enzyme activity was measured in 100000 u/g）. It can comprehensively improve flour product quality if lipase work with food grade xylanase,fungalα-amylase and glucose oxidase.
2 For leather working industry
In the leatherworking industry, lipase The enzyme is specific to the fat in the leather. It can soften the raw materials uniformly under mild conditions; increase leather yield on the basis of reducing the amount of chemicals; reduce skin wrinkles with remarkable effect. The enzyme is often used in the process of degreasing and softening. Recommended dosage: 0.02-0.06% (on the base of quantity of raw material, activity is 100000 u/g) . Work for 30-120min in 30-40℃. Lipase usually work with alkaline protease, in this way, it can optimize the effect.
3 For feed industry
When lipase added in the feed, it can release the short chain fatty acids; improve the utilization of raw materials; improved feed flavor. Recommended dosage: 0.01-0.05% (on the base of quantity of raw material, activity is 100000 u/g)
4 For papermaking industry
In the papermaking industry, lipase can be used in the process of mechanical pulping and deinking agent for waster paper. In the process of pulping, lipase can remove triglycerides in pulp; it can improve the efficiency of the deinking as deinking agent for waster paper. Recommended dosage: 0.04-0.10L/t pulping (activity is 100000 u/g).
Lipase is a kind of serine hydrolase which can catalyze and hydrolyze fatty glyceride into glycerol and fatty acids. An important feature of the hydrolysis reaction is that it is carried out in the oil - water interface. The enzyme also can catalyzes the synthesis and exchange reaction of esters.
Should be stored in a dry and cool place, avoiding insolation and damp.
25℃, 12 months, enzymatic activity remains≥90%. Increase dosage after shelf life.
Enzyme preparations belong to protein, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
