【瘦肉精的危害】
“瘦肉精”進(jìn)入動(dòng)物體內(nèi)后主要分布于肝臟。肌肉中含量較肝臟低很多。人攝入后在體內(nèi)存留時(shí)間較長(zhǎng),其不良反應(yīng)主要有:可引起心率加速,特別是原有心律失常的病例更易發(fā)生心臟反應(yīng),可見心室早搏、ST段與T波幅壓低,還會(huì)發(fā)出肌肉震顫,引發(fā)四肢、面頸部骨骼肌震顫,尤其是交感神經(jīng)功能亢進(jìn)的病例更易發(fā)生。此外,還可引起代謝紊亂、血鉀降低,引起心慌、肌肉震顫、頭痛以及臉部潮紅等。對(duì)心率失常、高血壓、青光眼、糖尿病、甲狀腺機(jī)能亢進(jìn)等疾病的患者有較大危害。

基于此科學(xué)家們認(rèn)為用動(dòng)物實(shí)驗(yàn)的結(jié)果來推測(cè)其在人體中的表現(xiàn)還是合理的。這六位志愿者還接受了不同的用量,來考察對(duì)身體狀況的影響。在每公斤體重的用量不超過67微克的情況下,沒有觀察到對(duì)人體有不良影響。把這個(gè)量除以一個(gè)50左右的“安全系數(shù)”,F(xiàn)DA認(rèn)為每天可接受的攝入量是每公斤體重1.25微克。據(jù)此,他們規(guī)定牛肉和豬肉中允許的Ractopamine殘留量分別是30和50 ppb(ppb是十億分之一)。在這個(gè)殘留量下,一個(gè)50公斤的人每天吃上兩斤半豬肉或者四斤牛肉都還是很安全的。加拿大和WHO的標(biāo)準(zhǔn)稍高一些,豬肉中的允許殘留是40ppb,而瘦肉精糧農(nóng)組織則是10ppb。日本和新西蘭比較有趣,本國(guó)的生產(chǎn)不許使用,但是進(jìn)口豬肉允許10ppb的殘留。總的來說,還是只有少數(shù)國(guó)家允許使用,包括中國(guó)在內(nèi)的絕大多數(shù)國(guó)家是禁用的。
Ractopamine或者別的動(dòng)物生長(zhǎng)添加劑,禁用與否應(yīng)該是一個(gè)技術(shù)問題。對(duì)于毒性研究的設(shè)計(jì)是否合理,推理是否嚴(yán)密,安全系數(shù)是否足夠大,以及決策是否有足夠的科學(xué)支持,人們*可以提出質(zhì)疑。但是,如果連物質(zhì)名稱都不清楚,僅僅是因?yàn)樽嫦葲]有用過就拒絕接受,或者認(rèn)為改變了動(dòng)物“天然”的生長(zhǎng)方式就反對(duì),跟一百多年前的人們對(duì)于汽車的恐慌并無區(qū)別。如果主管部門只是為了迎合民意而禁止,那么實(shí)在是一個(gè)社會(huì)的悲哀。
三聚氰胺的*引起了社會(huì)對(duì)食品添加劑的關(guān)注,不過,其實(shí)三聚氰胺根本就不是食品添加劑。公眾對(duì)于食品添加劑的恐慌,更多是出于一種對(duì)陌生事物的懷疑。
不知不覺,我在美國(guó)從事食品領(lǐng)域的研究工作已經(jīng)五年了,其間接觸過各種重要的食品添加劑類型。雖然我的專業(yè)里有“食品”二字,不過真正開始做具體的食品研發(fā)是差不多快畢業(yè)的時(shí)候。
為什么要用添加劑——布丁的故事
當(dāng)時(shí),實(shí)驗(yàn)室的一個(gè)博后要走了,老板就要我接過她手頭的項(xiàng)目,開發(fā)基于大豆蛋白的布丁產(chǎn)品。布丁是一種形態(tài)介于糨糊和果凍之間的甜品,傳統(tǒng)上是用牛奶蛋白做的。
但是一來牛奶蛋白越來越貴,二來牛奶產(chǎn)品中附帶比較多的膽固醇,而大豆蛋白價(jià)格便宜,沒有膽固醇問題,不管在經(jīng)濟(jì)還是營(yíng)養(yǎng)方面都有一定的優(yōu)勢(shì),所以州政府積極推動(dòng)大豆產(chǎn)品的研發(fā)。
不過大豆蛋白代替牛奶蛋白后,生產(chǎn)出來的布丁在味道、口感、穩(wěn)定上都不如以前,所以就要使用適當(dāng)?shù)氖称诽砑觿﹣砀纳七@些不滿意的方面。我接手的時(shí)候?qū)嶒?yàn)室研究部分已經(jīng)做完了,主要是加強(qiáng)了乳化劑的使用,并且用玉米糖漿來改善口味和增加粘度。我的工作是要在車間里進(jìn)行連續(xù)生產(chǎn)。碰到的*個(gè)問題就是加熱——因?yàn)橐?guī)模大了之后受熱不均勻,等到zui里面的加熱透了外面的已經(jīng)糊了,而不*熟透又達(dá)不到法律對(duì)于滅菌的要求。在一次進(jìn)展匯報(bào)的時(shí)候,一個(gè)教授問:“為什么不用糖替代品來提高對(duì)溫度的穩(wěn)定性呢?”就改善口味而言,用糖替代品是可以的,但是在布丁里糖漿還有增稠的作用,所以就行不通了。

Based on the scientists believe that the results of animal experiments to speculate that its performance in the human body is still reasonable. The six volunteers also accepted different doses to examine the impact on their health. No adverse effect on the human body was observed at a dose of no more than 67 micrograms per kilogram of body weight. By dividing this amount by a "safety factor" of about 50, the FDA considers the acceptable daily intake to be 1.25 micrograms per kilogram of body weight. Accordingly, they stipulate that the allowable Ractopamine residues in beef and pork are 30 and 50 ppb respectively (ppb is one billionth). At this residual amount, it is still safe for a 50 kilogram person to eat two pounds of half pork or four pounds of beef a day. The Canadian and WHO standards are slightly higher, with 40 ppb in pork and 10 ppb in lean meat. Japan and New Zealand are more interesting, domestic production is not allowed, but imports of pork allow 10ppb of residue. In general, only a few countries are allowed to use the vast majority of countries, including China are banned.
Ractopamine or other animal growth additives, disabled or not should be a technical issue. It is entirely up to question whether the toxicity study is properly designed, reasoned closely, if the safety factor is large enough and if there is enough scientific support for decision making. However, even if the substance name is not clear, it is rejected only because the ancestor has not used it, or it is opposed to changing the animal's "natural" mode of growth, as opposed to the fear of the car more than a hundred years ago . If the competent authorities are only banned to cater to public opinion, then it is indeed a social tragedy.
The well-known melamine has aroused the community's concern about food additives, but in fact, melamine is simply not a food additive. Public panic about food additives, more out of a suspicion of strange things.
Unconsciously, I have been engaged in the field of food research in the United States for five years, during which a variety of important food additives have been exposed. Although there is a word for "food" in my specialty, it is almost time to really begin to do specific food research and development.
Why use additives - pudding story
At that time, after a booming laboratory, my boss asked me to take over the project she was working on to develop pudding products based on soy protein. Pudding is a dessert that is in the form of paste and jelly, traditionally made with milk protein.
However, milk protein is more and more expensive, and secondly, milk products contain more cholesterol, while soy protein is cheap and free from cholesterol. No matter in economy or nutrition, the state government actively promotes soybean products R & D.
However, soy protein instead of milk protein, the production of pudding in the taste, taste, stability are not as good as before, it is necessary to use appropriate food additives to improve these dissatisfied aspects. When I took over the laboratory research part has been done, mainly to strengthen the use of emulsifiers, and corn syrup to improve the taste and increase viscosity. My job is to make continuous production in the workshop. The first problem we encountered was heating - because of the uneven heating after the big scale, until the inside of the innermost heating had gone out of the way and was not compley cooked and could not meet the legal requirements for sterilization. In a progress report, a professor asks: "Why do not sugar substitutes to increase temperature stability?" To improve the taste, the use of sugar substitutes is okay, but the thickening of the syrup in the pudding The role, so it will not work.
