氧對精釀啤酒的影響有哪些

作者：山東天泰人氣：发布日期： 2021-08-20

信息摘要：

啤酒設備厂在酿造精釀啤酒时，通过专门的糖化过程，使精釀啤酒赋予醇正、香甜的口感，深受大家的追捧和喜爱。在糖化过程中，如果用氮气隔绝空气，避免氧化过程(如脂肪酸、多酚的氧化)，产品质量将得到提高。用这种方法生产的啤酒，陈旧性物质含量低，多酚和花青素含量高，还原能力强(用ITT值表示)，能有效防止氧化。

使用隋氣的缺點是麥芽成分分解過徹底，對澱粉分解沒有不利影響，但對蛋白質組成有不利影響。它會引起聚合物中含氮化合物的強烈分解，使啤酒的泡沫性能變差。這時可以采用高溫切割來限制蛋白質的過度分解。
在實際生産中，惰性氣體的使用非常困難。但是，以下措施可以顯著降低氧的吸收:第一，加料要細心操作。當醪液用量較小時，應降低攪拌器的轉速，防止産生渦流和吸入大量空氣;第二，從底部喂料，並混合醪;三是使用低氧沖泡水。

It seems hard to deprive engineering pursuits of the romance that is often attached to the business, and bring it down to a matter of commercial gain; but it is best to deal with facts, especially when such facts have an immediate bearing upon the general object in view. There is no intention in these remarks of disparaging the works of many noble men, who have given their means, their time, and sometimes their lives, to the advancement of the industrial arts, without hope or desire of any other reward than the satisfaction of having performed a duty; but we are dealing with facts, and no false colouring should prevent a learner from forming practical estimates of practical matters. 2. The percussive force of spouting water can be fully utilised if its motion is altogether arrested by the vanes of a wheel. The names of many priests will be found in the register of Belgian martyrs. I have mentioned already some who, although innocent, gave their life for their country. During my week's stay at Louvain I heard of other cases. The priest of Corbeek-Loo, for example, was simply tortured to death on account of one of his sermons in which he said that the fight of the Belgian army was beauti142ful "because it lawfully resists an unlawful invasion," and further for announcing a Holy Requiem Mass for the souls of the "murdered" citizens. I have been able to assist a good many of these unfortunate people by bandaging the wounds with the dressing they gave me, or getting some water for them from some house in the neighbourhood; and one, who had fallen down exhausted by pain, I carried into a house. 84 They thought very well of the idea. There were two rooms to the cabin where they were, the big sitting room and the small bedchamber beyond. Kirby went into the bedroom and came out with two rifles and a revolver. He put the revolver into his wife's hands. "I'll do my best, you know, dear. But if I'm done for, if there is no hope for you and the children, use it," he said. And added, "You understand?" "Shorty's all right if he don't get a setback. The danger from the blow on his head is pretty near past, if something don't come in to make further complications. He has been pulled down pretty badly by the low fever which has been epidemic here since we have settled down in camp, but he seems to be coming out from it all right." "Where?" asked Si, running up to him. "Be patient," Shorty consoled him. "Your three years's only begun. You'll have lots o' chances yit. But if I ketch you shootin' at any more white birches I'll tie you up by the thumbs." "That reminds me," said Shorty, "that our squad o' recruits'll probably fill up the rijimint so's to give McBiddle his eagle. They'll be 'round presently to divide up the squad and assign 'em to companies. As all the companies is about equally strong, they'll divide 'em equally—that'll make six and one-half boys to each company. Capt. McGillicuddy bein' the senior Captain, is to have first choice. We want to pick out the best six and one-half for our company and put 'em in one squad at the right or left, and give the Captain the wink to choose 'em." "Respected Miss Maria, what a fine writer you are. Yore She ran out of the house. Away on Boarzell a man plodded and stumbled. She saw him stagger as the wind battered him, reel and nearly fall among the treacheries of the dead heather. He was like a drunken man, and she knew that he was drunk with shame. "And have not I," said Turner, whom an extra cup had made more than usually a braggart; "Have not I forged as many spear-heads as ye can find handles for? and has not John Tickle, the London doublet-maker, made me sixty as stout leathern doublets as man could wish to wear? and can I not bring the tough sinews of the brave Kentish men to strike down the hirelings of that foul council which has brought all this misery on the people?—and will ye talk of your pitiful gifts? Am not I the right hand of the prophet?——" HoME ai人体艺术图片 ENTER NUMBET 009www.vooboo.org.cn
