玉米漿幹粉：新舊玉米的辨別

玉米漿幹粉厂家要想生产出优质的玉米漿幹粉，对玉米品质的把控很重要，当然了用新鲜玉米制成的玉米漿幹粉的质量比陈玉米制成的玉米漿幹粉要好。那么新玉米和陈玉米之间有什么区别，两者之间该怎么辨别？

如何辨別新玉米和陳玉米？

1、形態區別主要是種子光澤。與新種子(同一品種)相比陳種子經過長時間的貯存幹燥，種子自身呼吸養分消耗，往往顔色較暗，胚部較硬，用手掐其胚部角質較少，粉質較多。陳種易被米象等蟲蛀，往往胚部有細圓孔等。將手伸進種子袋裏面抽出時，手上有粉末。

2、生理區別：陳的種子生活力弱，發芽率和發芽勢都比新種子低。田間拱土能力差，這也是生産上常發生的“有芽無勢”，種子在土中已發芽但扭曲，無法露出地面形成幼苗的原因。

3、種子生活力自測化學方法很多，可用紅墨水染色法。按1：60的比例將紅墨水配成溶液，將種子浸泡15分後取出觀察，種胚未被染成紅色或染色較淺的爲有生活力種子。

我司生产的玉米漿幹粉采用优质新鲜玉米浆，玉米浆在使用前，会经过去除杂质、研磨、洗涤，然后将不溶性杂质去除，再采用蒸汽低温喷雾干燥，产品无焦化、糊化现象，有效成分未破坏。关于新旧玉米的辨别的相关内容就先为大家介绍到这里了，希望对大家有所帮助，还有关于玉米漿幹粉的有关问题欢迎随时咨询。

ALLAHABAD “Larry, they’ve spotted that-there boat,” Jeff spoke through the tube to the young pilot. “Yep. More to the left. That’s it—both at the same time! Stick to the left, rudder, too. Good boy. Now the stick comes back to neutral. Hold her as she is—better cut down the throttle a little as we bank and turn to the left.” There was a bright I. D. blanket spread on the ground a little way back from the fire, and she threw herself down upon it. All that was picturesque in his memories of history flashed back to Cairness, as he took his place beside Landor on the log and looked at her. Boadicea might have sat so in the depths of the Icenean forests, in the light of the torches of the Druids. So the Babylonian queen might have rested in the midst of her victorious armies, or she of Palmyra, after the lion hunt in the deserts of Syria. Her eyes, red lighted beneath the shadowing lashes, met his. Then she glanced away into the blackness of the pine forest, and calling her dog to lie down beside her, stroked its silky red head. The 200th Ind. was raging along the foot of the wall, trying to find a cleft in it by which they could climb to the top and get at their foes. Standing a few yards in the rear, under a gigantic white-oak, whose thick branches promised protection from the crashing bowlders, the Colonel was sending parties to explore every place that seemed hopeful, and report to him. When Si came up with his squad he was directed to go to the extreme left, and see what he could find. "Give me that bandage," said the Surgeon just before he hurried away. "Take this sticking-plaster and draw the lips of the wound together, and if you keep the dirt out it may heal without a scar." As they headed toward the big front doors others followed, but there was no use bothering about that. When Cadnan opened the door, in fact, the others fell back and remained, staring, until it had shut behind them. There was the great noise of bells and buzzers—but that had been going on, Cadnan realized, even before they had begun. Outside, the spot-lights seemed weaker. There was smoke everywhere, and ahead the forest was a black and frightening mass. "No, to me." "Perhaps she'll get you before then." HoME 色先锋草莓av天天日ENTER NUMBET 003www.www10908.com.cn
