Lactose intolerance is non-infectious diarrhea caused by the lactose contained in milk or dairy products which cannot be completed digested because of lack of lactase in the body. It is also called Lactase Deficiency. Saccharides contained in breast milk and cow milk is mainly lactose. When lack of lactase in the body, part of lactose will be digested and fermented by intestinal bacteria and forms a mass of carbon dioxide gas.It can lead to the expansion of intestinal tract and the strengthening of intestinal peristalsis. It brings borborygmus, diarrhea, abdominal distension and so on which is called lactose intolerance.The Acid Lactase from Aspergillus oryzae has a high activity at low pH (pH3.5~5.5) making it particularly suitable for digest lactose in the stomach, and it’s therefore ideal for use in the dietary supplements as digestive aid to effectively relieve Lactose intolerance.

7.Effects of metal ions on enzyme activity: certain concentrations of Cu2+, Zn2+, Mn2+, Fe2+, Mg2+ have activating effects, EDTA, Ba2+ and Ag+ has inhibiting effects.
APPLICATION:
The Lactase from Aspergillus oryzae has a high activity at low pH (pH3.5～5.5), making it particularly suitable to digest lactose in acid conditions.
Usually it is used in dry mixes containing lactose, lactase type tablets or in capsules for nutraceutical applications.
It can also be used to produce Lactose-free products such as yogurt, ice cream; and in the production of galactooligosaccharides (GOS).
PACKAGING: 20KG/drum, 25KG/drum
STORAGE & SHELF LIFE: 2 years when stored at room temperature, away from direct sunlight, cold storage is better.
