Product Description
The Alpha-galactosidase is produced by submerged fermentation of a selected microbial strain followed by purification, formulation, and drying. It is used to remove anti-nutrient factors, such as raffinose and stachyose, to solve digestion problems. The product is also capable of hydrolyzing galactomannans synergistically with mannase.
Mechanism
Alpha-galactosidase is a homodimeric glycoprotein that splits off the terminal alpha-galactosyl moieties. It is able to catalyze the hydrolysis of melibiose into galactose and glucose and therefore also called mellibiase. Since there are anti-nutritional carbohydrates, i.e., raffinose and stachyose, containing galactose residuals linked with bond in α-configuration in some feed raw materials, the use of the enzyme will remove these anti-nutrients and convert them into readily absorbable nutrients.

Recommended Dosage
The recommended dosage is 0.01-1 kg/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 types of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes, or nasal mucosa. Any direct contact with the human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
