啤酒中出現異常酵母味該如何解決

作者：山東天泰人氣：发布日期： 2021-05-18

信息摘要：

酵母味是一種令人不舒服的氣味和口味,酵母自溶時尤其明顯。帶有酵母味的啤酒往往具有pH值偏高,色度偏深和泡沫性能較差的特點。

導致啤酒異味的因素主要有:原料、工藝、有害物質汙染、微生物汙染、運輸和銷售條件。
酵母味是一種令人不舒服的氣味和口味,酵母自溶時尤其明顯。帶有酵母味的啤酒往往具有pH值偏高,色度偏深和泡沫性能較差的特點。
(1)導致酵母味的原因
A.贮酒温度较高和贮酒时间过长,酵母自溶并释出脂肪酸。研究已经证明,这些物质会使啤酒具有不舒适的异香味,并对泡沫产生不利的影响,其中乙酸乙酯和十二酸乙酯含量高时可共同作用形成酵母味,但其中之一不会单独起作用。
B.衛生問題如管道內生長黴菌,也會導致啤酒的酵母味。
(2)防止措施
A.锥形罐的后酵期间应多次排放酵母,防止酵母自溶。
B.检验酵母,使其保持良好的生理状态且使用代数不能太高。
C.注意检测啤酒中癸酸酯的含量。当酵母自溶时癸酸酯的含量明显升高,因此它是酵母味的指示物质。可分析它的含量来判断啤酒是否有酵母味。

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 0090992.org.cn
