Food Grade Powder Lipase Enzyme
Introduction: 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℃-50℃) and at neutral to alkaline pH conditions. It can also be used for leather processing, feed, papermaking, detergent, biodiesel, and in other industries.
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 the oil-water interface. Lipase can also catalyze ester synthesis and interesterification. The reactions can be illustrated as follows:

Application:
Baking industry: Lipase is beneficial to dough handling properties, gluten strengthening, and crumb texture. Therefore, it has been used in the baking industry to improve dough stability, better crumb structure with better whiteness and crust luster, and increase the 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.
Leather processing: Lipase is normally used for degreasing and softening of leather as an eco-friendly solution, bringing benefits of even and efficient degreasing without unwanted effects, reducing the use of chemicals under mild conditions, and increasing yield while improving the 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.
Feed industry: 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.
Papermaking industry: Lipase has been successfully used for pitch control during mechanical pulping and deinking of used paper with remarkable effects.
Recommended Dosage:
The recommended dosage is 0.01-0.5 kg/t DS. The dosage has to be optimized based on each application, the raw material specifications, product expectations, and processing parameters. It is better to begin the test with the convenient volume.
Package and Storage:
Package: 1 kg / bag
Storage: Keep sealed in a dry and cool place and avoid direct sunlight. Slight sedimentation is acceptable since it will not impact the performance of the product.
Shelf Life: 12 months in a dry and cool place
