Improve A Corn The Research Of The Powder Rate

The corn is the grain crops and the industrial crop which the peopleknew very well. But cannot the very good assurance production cornbest time but causes the corn when the processing appear such as thestarch flour yield as a result of the people to be low,The germination percentage is low,The corn seed quality poorly changes and so on a series of questions,In order to avoid having the above problem to reduce the nonessentialloss,We study the corn to bud to lead well,The flour yield is high,The starch protein condition nitrogen and the fat achieved the highesttime is corn's additional ripening time. The definite corn'sadditional ripening time has many kinds of method,This experiment mainly through uses the fat iodine value to determine.applies the way of soak in it, machine the natural air-dried maize grain in different period (earlier stage of after-ripening, midterm of period of after-ripening and later stage of period of after-ripening), make them into maize starch, and measure the power of rate; meanwhile , compares them with the artificial maize grain that dry. Achieve a conclusion about the new reaped maize that as the accomplishing of the period of after-ripening, the power of rate is raise too. And the power of rate of the natural maize by air-dry is higher than the artificial maize that dry.this research adopt the type of kejldahl to measure the protein proportion in maize starch by natural air. The result is probably 0.48%.Tt is shorter than the one dried artificially 0.18%.Strach is melted by case of strach.This is a case why the rate of corn strach was very lowest.This experimental material is that dry corn by the wind and coast corn measure the size of vigor of strach case .To offer the accordance for choose the sitable case .To offer the accordance for choose the sitable situation of corn to under the high produce pressed in industury .Malt sugar is one of the production of strach water break down .It can recover水杨酸to the brownred水杨酸,by the method of divide light to measure the later's light's. And sure the strsch case's vigor on this foundation, 37.6mg dry by the wind ,18.0mg after toast. In order to asure it don't relation which the size of vigor of strach case .As material, with divide all luminosity law determine maize candy supersession limit speed enzyme apple sour dehydrogenation vigor of enzyme in front and at the back of drying with the Great Wall 799 maize, result indicate apple sour dehydrogenation of maize vigor of enzyme 60U/g and 29 U/g before and after drying...
