| titleOfInvention | A kind of method for producing alpha amylase |
| abstract | The invention discloses a kind of method for producing alpha amylase, weighs the wheat seed crushing of firm rudiment, absolute ethyl alcohol is added into wheat seed, and after 1 5h of immersion, centrifugation obtains the wheat seed crossed through soaked in absolute ethyl alcohol；Ethanol water is added into the wheat seed crossed through soaked in absolute ethyl alcohol, is then centrifuged after the 5h of ultrasonic extraction 2, obtains supernatant；Acetone, chloroform, n-butanol are added into supernatant, is then extracted, obtains raffinate A；3 5h are stood after xanthans, potassium permanganate, ethanol, methanol, sodium-acetate buffer are well mixed, mixed liquor A is made；Mixed liquor A and raffinate A are mixed into 1 6h, is then extracted, obtains raffinate B；Extract B is dried in vacuo, produces alpha amylase.The present invention has extracted alpha amylase by ultrasonic extraction and screening from the wheat seed of firm rudiment, and preparation technology is simple, and easily controllable, realization, production cost is low, can effectively improve economic benefit. |
