Phospholipase enzyme for bakery Sunson SBE-02Li
Phospholipase SBE-02LI is produced by submerged fermentation of Aspergillus niger followed by purification, formulation and drying. Phospholipase 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. If used together with xylanase, fungal α-amylase and glucose oxidase, it will contribute to the above improvements in a synergistic way.
MECHANISM
Phospholipase is a kind of hydrolase which can catalyze hydrolysis of phospholipids. The hydrolysis takes place on oil-water interface. Lipase can also catalyze ester synthesis and interesterification.

APPLICATION RECOMMENDATION
For bread producing: The recommended dosage is 1-20g per ton of flour. 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.
