酒花油制品简介

一、使用方法

对于普通酒花油，金麦推荐的添加量为1~3克/100升麦汁，完全取代原来酒花添加工艺中煮沸锅中添加的第3次酒花或香花。各用户可根据本地区消费者的口味习惯计算香花油的用量并经过实验进行调整，原则上香花油的添加量为原工艺中的第3遍酒花的5~10%，如果当地喜好香味浓的啤酒可以将添加量调整为3~5克/100升麦汁。

二、添加点及方法

采用适当的方法将原包装的香花油按计算的用量将香花油直接添加到煮沸锅中，在煮沸终了前5~10分钟加入。添加前注意将桶装酒花油上下混匀，以避免因包装桶中酒花油的浓度分层而造成添加不匀。

三、贮存方法及包装

酒花油可存放在室温下或酒花库中（3~25ºC）。酒花油系列产品的包装均为1公斤/ 桶。

酒花油是从酒花中萃取的，其萃取方式目前在国际上主要有两种：

液态二氧化碳（7摄氏度，4．0Mpa压力下）和超临界流态二氧化碳（50摄氏度和31．5Mpa压力下）

两种方法的区别在于：

1、液态二氧化碳萃取酒花的选择性高，主要萃取成分为α－酸、β－酸和酒花油，硬树脂和多酚物质则不易被萃取。其他如水分、脂肪酸、蜡质和色素等物质也远远低于超临界二氧化碳萃取。液态二氧化碳萃取的酒花油为黄色或棕黄色。因液态二氧化碳的萃取条件比较温和（7摄氏度和4．0Mpa压力下），又是在惰性气体二氧化碳条件下萃取的，故萃取的树脂物质极少降解或起化学变化，基本保持原酒花的酒花油成分，香气较柔和。

2、超临界流态二氧化碳萃取，系在50摄氏度和31．5Mpa压力下萃取，萃取的选择性差，萃取中含有部分硬树脂、多酚物质、脂肪酸、蜡质、叶绿素等成分。这种方式制备时间短，只有2．5小时，收得率高，而液态二氧化碳萃取需5．5小时。由于叶绿素的溶出，色泽呈深绿色或墨绿色，香气较浓郁但缺乏细腻。

第二篇：emily dickinson 艾米丽 迪金森 简介

Emily Dickinson

My favorite writer is Emily Dickinson.Like Whitman, she broke the limitations of her time.Though she left us more than 1770 poems, only several of these poems are published before she died.From her twentieth, she began to get rid of the contact with society.So we do not know much information about her, which made us feel hard to know the exact meaning of her poetry.Her style was influenced greatly by Emerson.Though she almost did not go to the outdoor, she lived a colorful spirit life.She was very important in American literature.The themes of Emily Dickinson’s poems are love, nature, doubt and faith, suffering, death and immortality.For example, she writes To Make a Prairie… and I Died for Beauty, but was Scarce.The style of her poems is terse and frequently imagistic style.That style is very modern and innovative.Dickinson explores the inside world.Her poetry is marked for her concise, direct and simple diction and syntax.Although she had normal and vivacious girlhood, her poetry illustrates the doctrine predestination and pessimism, so that her basic tone was tragic.She sees nature as both gaily

benevolent and cruel.On the ethical level she emphasizes free-will and human responsibility.Like Emerson, she holds that beauty, truth and goodness are ultimately one.She says “For Beauty,” I replied—“and I--for Truth--Themselves are One— we Brethren, are,” he said--

The artistic features of her poems lie in her innovation in rhyme and her structural patterns.She used “consonance” which means similarity of final consonants.For example, in Success Is Counted Sweetest, in the second stanza, “today” and “victory” are consonance.Another rhyme she used is assonance: the final vowels correspond, but the consonants are different.Her major pattern is that of a sermon: statement or introduction of topic, elaboration and conclusion.There are three variations of this major pattern.Firstly, the poet makes her initial announcement of topic in an unfigured line.Secondly, she uses a figure for that purpose.Thirdly, she repeated her statement and its elaboration a number of times before drawing a conclusion.The characters of Emily Dickinson’s poems are as follows: first, frequent use of dashes, such as the poem I Died for Beauty, but was Scarce;second, sporadic capitalization of nouns;third, convoluted and ungrammatical phrasing;forth, off-rhymes;innovation in rhyme;fifth,compressed, broken meters;sixth, bold and unconventional and often startling metaphors, for example, “ And so, as Kinsmen met a Night— We talked between the Rooms--Until the Moss had reached our lips— And covered up—our names--”;seventh, aphoristic wit;eighth, begin with “I”, such as “I’m nobody!Who are you”;ninth, ambiguity of meaning and syntax, this is because we do not have enough documents about Emily Dickinson;last, elliptical—she will say no more than she must, because she was influenced by the doctrine of her religion.
