This product is extracted from the deep fermentation of the liquid of the Jacus Spories. The product is a liquid dosage form. It is suitable for biopharmaceuticals, starch sugar, alcohol, beer, monosodium glutamate, fruit juice, fermentation industry, textile and other industries.

Product Features:

1. The way of action: This product is a type -1,4 glycoside bond. After the enzyme action, the viscosity of the vesicular starch can be dropped rapidly, and the hydrolysis generates the essence and a small amount of glucose and maltose.

2. Product specifications: 40000 U/G

3, P H's impact on enzyme vitality: the stable pH range of this product is 5.0-10.0, the effective pH range is 5.0-8.0, the most suitable pH range 5.5-7.0

4. The effect of temperature on enzyme vitality: the most suitable temperature of this product is above 90 ° C (continuous jet liquefaction, the temperature can also be 100-110 ° C)

5 The impact of calcium ions on enzyme vitality: The dependence of this product on calcium ions is not high, and the concentration of calcium ions should be kept in the range of 50-70mg/kg.

Products: Light yellow or white solid powder

Enzyme vitality definition:

above 70 ° C, under pH6.0 conditions, 1 minute, 1 minute, 1 minute 1 mg of liquefied soluble starch has become an enzyme amount of enzyme vitality required for the essence, which is represented by U/ML.

 

Enzyme activity: 40000u/g

 

Reference dosage: Generally calculated based on 8-15 units per gram of starch.

 

Execution criteria: GB 8275-2009

 

Save:

 

Survive more than 90% of the time at RT to avoid high temperature sun.

 

Application reference (for reference only):

1. Beer industry: After the auxiliary materials are mixed with water evenly, add 0.3 liters per ton of this product at a time (4 About 10,000 U/ml), quickly heating up, the best effect at 95-97 ° C. The temperature is heated to 100 ° C, the insulation is about 30 minutes, and the iodine solution experiment is liquefied.

 

2. The alcohol industry: The raw material is preferably 1.5mm in diameter, and the water ratio is mixed uniformly at 1: 3.5-4.0, and the water temperature is 45-55 ° C. Add about 0.6 liters/tons (40,000 U/ml) per ton of high stroke. After stirring, pump into the cooking heater. The temperature is controlled at 95-105 ° C, and the time is 100 minutes.

 

3. Industry such as monosodium glutamate, sodium sugar, and glucose: can be made into starch milk according to the process requirements. Essence If you use intermittent liquefaction, the liquefaction tank quickly heated to 95-100 ° C, and keep it for 30 minutesLeft and right; if the jet liquefaction is used, the spray temperature can be around 110 ° C, and it is maintained for 60 minutes at 98 ° C until the liquefaction is complete.

 

Note:

 

1. According to the specific situation of raw materials, equipment, and technology, you can adjust the amount

 

2. This product is more suitableCan slowly stir or flip the gap, the liquefaction time can be adjusted according to the process requirements.

 

3. If there is a small amount of precipitation, it can be stirred without affecting the effect.
