The fungal α-amylase is prepared from fermentation of Aspergillus niger. Comparison with the bacterial α-amylase whose optimal temperature is 60°C and the main product is starch dextrin, the optimal temperature of the fungal α-amylase is 40°C and its products consist of large amount of maltose, small amount of oligosaccharides and glucose. In recent years, as a new type of enzyme preparation, the fungal α-amylase has been widely used in the production of starch syrup, oligosaccharides, beer, flour, bread, steamed bread and other foods. It also has been used in animal husbandry and aquaculture.
1．Appearance: light brownish powder with less than 8% of water content.
2．Activity: 3,000 U/g
4， pH: 3.0-6.0
Definition of the unit of the enzyme activity: One unit (U/g or U/ml) is defined as 1 g (solid powder) or 1 ml (liquid) of enzyme to produce reducing sugars equivalent to 10 mg of glucose in a catalytic reaction (pH 5.0 at 40°C in 30 min (QB/2526-2001).
1.In bread baking, the adding the fungal α-amylase in the flour can promote fermentation, reduce the viscosity of dough, increase the sugar content of dough, improve the taste, outer color, and baking quality of bread, and extend the shelf time of the bakery foods.
2.In alcohol production and brewing industry, adding the fungal α-amylase can make the enzymes in the fermentation evenly distributed, increase the saccharification, yeast growth and the yield of alcohol.
3.In feed industry, adding the fungal α-amylase combined with semicellulase can increase the digestion of cereals and utilization of feeds and reduce the production cost. The amount of supplementation are as follows:
(1)For soybean meal based diets of laying chickens, ducks and geese: 80-100 g/ton.
(2)For soybean meal based diets of broilers and chicklings: 100-150 g/ton.
(3)For soybean meal based diets of piglets and aquatic animals: 150-200 g/ton.
(4)For miscellaneous meal based diets of laying chickens, ducks and geese: 100-120 g/ton.
(5)For miscellaneous meal based diets of broilers and chicklings: 120-150 g/ton.
(6)For miscellaneous meal based diets of piglets and aquatic animals: 150-200 g/ton.
Specification: 20 kg/bag
Store in dry and cool (below 25°C) area with ventilation. During transportation, avoid direct exposure to strong sunlight, rain and moisture. The enzymes will lose activity at high temperature or under strong sunlight. The enzyme activity can be maintained up to 90% for 6 months when stored at room temperature.
