淀粉酶Amylase

Medium temperatureα—amylase

It can hydrolyze the alpha -1.4 glucoside bond in the starch molecular, it can cut down them into short chain dextrin in different length and small amounts of low molecular carbohydrates, both amylose and amylopectin are decomposed with no rules which decrease the viscosity of starch paste rapidly, it’s called liquefaction role, so the α—amylase is also called liquefying enzyme.

Product feature:

1.Thermal stability: It’s stable under 60 ℃, the optimum temperature is 60-70 ℃, it is applicable in temperature up to 90 ℃ in the liquefied process.

2.PH stability: It is stable at PH6.0-7.0, the optimum PH is 6.0, it will lose activity seriously under PH5.0.

3.The affection of concentration of calcium ion to the enzyme activity: Calcium ions can obviously improve the stability of enzyme activity, without calcium ion, enzyme activity will be completely lost.

Solid product is packed with textile bag, 20kg/ bag.

Liquid product is packed with plastic barrel, 25kg/barrel or based on customer requirements. The product is bioactive substances, sunlight, temperature and humidity can cause enzyme inactivation. It should avoid direct sunshine and be kept in a cool and dry place.

Thermostable α - amylase

Thermostable α – amylase is fermented and refined from the Bacillus licheniformis, it has good heat resistance, liquefaction under high temperature is quickly and thoroughly, the protein in liquefied liquid has the feture of good flocculation, obvious stratification, rapid filtration, less dosage and convenient usage, it can help to simplify the process, improve quality, raise yield, reduce cost, save energy and improve utilization rate of equipment.

It’s widely used in starch processing, sugar, monosodium glutamate, alcohol, beer, citric acid, textile printing and dyeing, paper making and other fermentation industries.

Product feature:

High temperature resistant alpha - amylase in high temperature rapid hydrolysis of starch molecules in а - 1.4 glycosidic linkage, from starch molecular internal arbitrary cutting growth short not short keys dextrin and small amounts of oligosaccharides, which makes the viscosity of starch pastes decreased rapidly, if the liquefaction time is long, there will be a small amount of glucose and maltose to be produced.

Qualification standard:

Enzyme activity definition:

It’s marked as grams of soluble starch liquefied by.1ml of liquid enzyme in 1 hour at temperature of 70℃ and PH 6.0, the unit is u/ml.

Product standards:

It’s complied with the light industry standard of People's Republic of China. QB/T2306—97

Conditions:

The effects of calcium ions on enzyme activity stability

With the presence of low concentration calcium, the product has good stability, to hydrolyze the starch, 50 -70mg/L calcium ion is recommended to be added into it. (usually it doesn’t need calcium ions)

The influence of PH

The optimum PH range is PH6.0 - 6.2, the effective PH range is 5-8

The influence of temperature

The optimum temperature range: 95 ℃ - 97 ℃, the effective range of temperature: 90 ℃-100℃

The instantaneous temperature in the jet liquefaction process can be up to 105 ℃-110℃, the thermal stability of the product is very good.

Package and storage：

25KG plastic barrel

Liquid product is packed with plastic barrel, 25kg/barrel or based on customer requirements. The product is bioactive substances, sunlight, temperature and humidity can cause enzyme inactivation. It should avoid direct sunshine and be kept in a cool and dry place.

This product belongs to biological active substances, it should be placed in the dry place in low temperature, direct sunlight should be avoided. In room temperature (25 ℃) the enzyme activity should be not lower than the labeled in six months, enzyme activity should be not lower than the labeled for one year if stored under 5 ℃. In the case of a small amount of precipitation, shake  it even before using it, the effect will not change.

超氧化物歧化酶（SOD）Superoxide Dismutase

Superoxide Dismutase (Superoxide Dismutase abbreviated SOD) is a new type of enzyme preparation. It is widely spread in the biosphere almost from animal to plant, it even exists in from the people to single cell organisms. SOD is the natural enemy of oxygen free radicals in the body and be the NO.1 killer, it is the source of life and health. SOD (superoxide dismutase) can effectively remove excess free radicals, it has effect of anti-aging, anti-tumor, anti fatigue and anti radiation. It is widely used in medicine and health care products, cosmetics, functional food and beverage etc.

Application:

1. The most important function of SOD is anti-aging, it can remove excess superoxide anion free radicals and play the role of slowing aging of organims.

2.SOD can significantly improve the immune function of human body, reduce the l diseases caused by the superoxide anion free radica, including cancer, inflammation, emphysema and cataract etc.

3.SOD can also enhance the resistance to inducing factors of superoxide anion free radical ,such as smoke, radiation, toxic chemicals and drugs.

4.SOD can improve the body's ability to adapt to the environment, it can help us get rid of the fatigue of the body and enhance the capacity of adaptation to the physical consumption.

SOD is mainly used in cosmetics and pharmaceutical industry, it has a great market prospect at home and abroad. SOD is listed in the national eleventh Five years Plan of bio medicine as the key project, year 2011 is the first year in the 12^th five year of the Twelfth Five Year Plan, SOD will be among the high-tech industrialization projects again which will be developed in priority, it marks the rise of SOD emerging industry in China health industry, it will push forward the health economy of all mankind.
