Liquid food grade lipase applicable for baking food leather pulp paper oleochemistry biodiesel

 

PRODUCT DESCRIPTION

 

Lipase is produced by submerged fermentation of Aspergillus niger followed by purification and formulation. The product has efficient hydrolytic activity within a wide range of temperature (30℃-80℃) and neutral to alkaline pH conditions. It catalyzes lipolysis, esterification and transesterification reaction.

 

MECHANISM

Lipase is a kind of serine hydrolase which can catalyze hydrolysis of triglyceride to finally produce Glycerol and fatty acids. The hydrolysis takes place on oil-water interface. Lipase can also catalyze ester synthesis and interesterification. The reactions can be illustrated as the following:

 

APPLICATION

Ø  Baking industry

Lipase is beneficial to dough handling properties, gluten strengthening and crumb texture. Therefore, it has been used in baking industry to improve dough stability, better crumb structure with better whiteness and crust luster, and increase volume of bread and steamed bun. It also makes steamed bun look whiter and shinier. If used together with xylanase, fungal α-amylase and glucose oxidase, it will contribute to the above improvements in a synergistic way.

 

Ø  Leather processing

l  Lipase is normally used for degreasing and softening of leather as an ecofriendly solution, bringing benefits of even and efficient degreasing without unwanted effect, reducing the use of chemicals under mild condition and increasing yield while improving quality of leather. The best performance can be obtained during softening when lipase is used jointly with alkaline protease in terms of less wrinkles and yield loss.

 

Ø  Feed industry

l  When lipase is added into the feed, it can release the short chain fatty acids and improve the utilization of raw materials while improving feed flavor.

 

Ø  Papermaking industry

l  Lipase has been successfully used for pitch control during mechanical pulping and deinking of used paper with remarkable effects.

 

Ø  Oleochemicals

l  Lipase is able to catalyze lipolysis or organic synthesis to produce various value-added oleochemicals

l  By trans-esterification lipase is used for biodiesel production from used oil or other cheap oil sources.

APPLICATION RECOMMENDATION

The recommended dosage is 0.01-0.5kg/t DS. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.

 

SAFE HANDLING PRECAUTIONS

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.

 

WARNINGS

Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
