金漢森酒花油簡介

酒花油制品簡介

一、使用方法

對于普通酒花油，金麥推薦的添加量為1~3克/100升麥汁，完全取代原來酒花添加工藝中煮沸鍋中添加的第3次酒花或香花。各用戶可根據(jù)本地區(qū)消費者的口味習(xí)慣計算香花油的用量并經(jīng)過實驗進行調(diào)整，原則上香花油的添加量為原工藝中的第3遍酒花的5~10%，如果當?shù)叵埠孟阄稘獾钠【瓶梢詫⑻砑恿空{(diào)整為3~5克/100升麥汁。

二、添加點及方法

采用適當?shù)姆椒▽⒃b的香花油按計算的用量將香花油直接添加到煮沸鍋中，在煮沸終了前5~10分鐘加入。添加前注意將桶裝酒花油上下混勻，以避免因包裝桶中酒花油的濃度分層而造成添加不勻。

三、貯存方法及包裝

酒花油可存放在室溫下或酒花庫中（3~25ºC）。酒花油系列產(chǎn)品的包裝均為1公斤/ 桶。

酒花油是從酒花中萃取的，其萃取方式目前在國際上主要有兩種：

液態(tài)二氧化碳（7攝氏度，4．0Mpa壓力下）和超臨界流態(tài)二氧化碳（50攝氏度和31．5Mpa壓力下）

兩種方法的區(qū)別在于：

1、液態(tài)二氧化碳萃取酒花的選擇性高，主要萃取成分為α－酸、β－酸和酒花油，硬樹脂和多酚物質(zhì)則不易被萃取。其他如水分、脂肪酸、蠟質(zhì)和色素等物質(zhì)也遠遠低于超臨界二氧化碳萃取。液態(tài)二氧化碳萃取的酒花油為黃色或棕黃色。因液態(tài)二氧化碳的萃取條件比較溫和（7攝氏度和4．0Mpa壓力下），又是在惰性氣體二氧化碳條件下萃取的，故萃取的樹脂物質(zhì)極少降解或起化學(xué)變化，基本保持原酒花的酒花油成分，香氣較柔和。

2、超臨界流態(tài)二氧化碳萃取，系在50攝氏度和31．5Mpa壓力下萃取，萃取的選擇性差，萃取中含有部分硬樹脂、多酚物質(zhì)、脂肪酸、蠟質(zhì)、葉綠素等成分。這種方式制備時間短，只有2．5小時，收得率高，而液態(tài)二氧化碳萃取需5．5小時。由于葉綠素的溶出，色澤呈深綠色或墨綠色，香氣較濃郁但缺乏細膩。

第二篇：emily dickinson 艾米麗 迪金森 簡介

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.
