核心提示 summary

　　“我买的奶茶，喝起来没有一点牛奶味。”10月17日上午，家住洛阳市西工区的王女士拨打本报热线反映。时下天气渐渐转凉，暖暖的奶茶成了消费者青睐的对象。面对街头五花八门的奶茶，消费者饮用时，难免心中“打鼓”：这些奶茶中是否含牛奶？其占多大比例呢？

　　“向奶茶中加些醋，就可知道是否含奶？！”记者搜索发现，最近网上一个鉴别奶茶中是否含牛奶的方法“迅速蹿红”，其鉴别依据就是：如果奶茶中含有牛奶，那么醋遇蛋白质就会起化学反应，生成絮状物；若奶茶中没有任何变化，那就基本不含奶。街头销售的奶茶中是否含牛奶？这种奶茶鉴别方法为何“爆红”？难道它真的靠谱吗？近日，记者通过连续实验和多方走访调查对此进行了验证。

市民：奶茶没奶味，心里直打鼓 citizens:Milk tea taste of milk didn't,Pretty scary

　　“感觉被戏弄了，真是窝火。”据王女士介绍，17日上午，她送女儿上学，路过中州中路一家奶茶店门口，女儿吵着要喝奶茶，拗不过女儿，便给孩子买了一杯4元钱的奶茶。奶茶店老板忙活了两三分钟，就把一杯热奶茶递了出来。“女儿尝了一口，就皱眉了，说‘一点奶味也没有’。”王女士说，女儿觉得不好喝，就把奶茶塞到她手里。王女士有些奇怪，尝了一口，结果“有一股很浓的甜味，很腻”。王女士说，奶茶没一点奶味。

"Feeling be teased,Is really irritated."According to wang introduced,17 morning,She sent her daughter to school,Pass by zhongzhou road a milk tea shop,daughter noisy want to drink tea with milk,Her daughter,Gave children bought a cup of 4 yuan milk tea.Milk tea shopkeeper be busy two or three minutes,Put a cup of hot milk tea handed out."daughter tastes,Will frown the,said‘A little milk taste also have no’."Ms. Wang said,daughter feel bad to drink,Put milk tea plug to her hand.Ms. Wang some strange,tastes,The results"Has a very thick sweet taste,boring".Ms. Wang said,Milk tea not a little milk taste.

　　“家里订过鲜牛奶，这奶茶喝起来一点都没有牛奶的味。”王女士打起了问号。她觉得这奶茶肯定不含奶。

"Home order a fresh milk,This milk tea drink up were not a bit of milk taste."Ms. Wang dozen have a question mark.She felt this milk tea must not contain milk.

　　越想越觉得不对劲，王女士再次走进奶茶店，想要找店主讨个说法。店主一口咬定奶茶里肯定含牛奶，并肯定地说：“奶茶里面不含奶，还叫什么‘奶茶’？”

More think more felt something was wrong,Ms. Wang again into the milk tea shop,Want to find the shopkeeper make a statement.The shopkeeper contended the affirmation in milk tea with milk,And certainly:"Milk tea inside do not contain milk,Also call what‘Milk tea’?"

　　“花钱买了一肚子气。”王女士心里很不痛快，但是苦于没有证据证明奶茶不含奶，只得愤愤地离开了奶茶店。

爆料：街头奶茶其实不含奶 kept:Street milk tea actually do not contain milk

　　奶茶没奶味，那么这些街头店铺自制奶茶究竟是否含牛奶呢？18日，记者以准备开办奶茶店为名，来到洛阳市解放路春晴路口进行暗访，这里集中了市内多家食品化工店。

Milk tea taste of milk didn't,So these street shops homemade milk tea with milk? Whether or not?18,Reporter to prepare for open milk tea shop name,Came to luoyang jiefang road spring fine intersection for investigations,Here on the city's food chemical shop.

　　在一家专卖奶茶配料的直营店里，店员介绍称，奶茶粉是街头制作奶茶的主要原料，其有椰果、原味、草莓等10余种口味，每袋奶茶粉售价12元，但需搭配奶精、炼乳等原料，才能制作出奶茶。

In a monopoly milk tea ingredients in the regular distributors,Shop assistant introduction says,Milk tea powder is the main raw material milk tea street production,It has coconut palm fruit/taste/Strawberry, etc more than 10 kinds of taste,Each bag tea with milk powder price 12 yuan,But is available with cream/Condensed milk raw materials such as,To produce milk tea.

　　还有一种“三合一”的奶茶粉，里面包含有奶茶粉、奶精等原料，“买回去拿开水一冲就完事儿”。该店员极力向记者推荐使用这种“三合一”包装的奶茶粉，称制作起来不费事儿，“一袋怎么着也能冲个三四十杯吧”。

Still have a kind of"triad"Of milk tea powder,Which contains the tea with milk powder/Cream raw materials such as,"Buy back to take a running water is finished".The shop assistant strongly recommend this to the reporter"triad"Packing of milk tea powder,Say making up to no fee business,"A bag of how wear also can flush a 40 cup".

　　“街头奶茶店中的奶茶都是用奶茶粉制作的吗？”记者问。营业员反问：“要不然怎么做奶茶？”而记者仔细浏览奶茶粉原料发现，根本找不到牛奶成分。

"Street milk tea shop is the milk tea with milk tea powder production?"The reporter asked.S rhetorical question:"Or how do milk tea?"And the reporter peruse the milk tea powder materials found,Can't find milk composition.

　　调查中，一名业内人士告诉记者，街头奶茶中不含牛奶，早已是业界公开的秘密。

In the investigation,A personage inside course of study tells a reporter,Street milk tea do not contain milk,Industry is already open secret.

　　业内人士常华(化名)曾在某连锁奶茶店做过兼职。据她介绍，不少街头店铺的奶茶都是用奶茶粉冲泡出来的，“有些店里的奶茶则是用奶精和果味粉配出来的。现在街头小店铺制作奶茶基本用的都是奶茶粉和奶精，但是质量有好有坏，价钱也不一样”。不过，小常也坦言：在一些大型的连锁奶茶店中，奶茶制作过程较为规范，确实是使用鲜奶做原料。

The personage inside course of study ChangHua(alias)Once in a chain milk tea shop a part-time.She said,A lot of street shop milk tea with milk tea powder brew is out,"Some of the milk tea is with cream and fruit flavor powder with out.Now the street small shops make tea with milk basic are used in tea with milk powder and milk essence,But quality is good or bad,The price is different also".but,Small often also said:In some large chain milk tea shop,Milk tea manufacture process standard,Really is the use of fresh milk do raw materials.

网曝：奶茶是否含奶可鉴别，记者实验求证 Net exposure:Whether milk tea with milk can identify,Reporter experimental verification

　　事实上，对于街头所售奶茶到底含不含牛奶的质疑由来已久。与王女士遭遇类似，一般市民都因无法鉴别奶茶到底是否含奶而忍气吞声。

In fact,For street sell the milk tea contains does not contain milk has been questioned.And wang encounter similar,The general public are unable to identify whether milk tea with milk and submit to humiliation.

　　记者搜索发现，最近，一个鉴别奶茶中是否含有奶的方法迅速蹿红，引起众多网友的极大兴趣。

Reporter found that search,recently,A identify whether milk tea contain milk method rapid leap up is red,Cause many users to great interest.

　　该方法是，在奶茶中加入适量食醋，醋遇蛋白质发生化学反应，出现絮状物；如果奶茶没有变化，那就基本不含牛奶。

This method is,In the milk tea in adding suitable amount of vinegar,Vinegar in protein produce chemical reaction,Appear floc;If the tea with milk did not change,Then basic does not contain milk.

　　这个方法靠谱吗？以下为记者亲身实验：

This method by spectrum?The following is a reporter personal experiment:

　　实验时间：10月18日

The experiment time:On October 18

　　实验奶茶：

Experimental milk tea:

　　A。市区某奶茶店购买的中杯原味奶茶，3元一杯，颜色偏白

A.The city a milk tea shop to buy in the original milk tea cup,3 yuan a cup of,Color slants white

　　B。娃哈哈呦呦奶茶，4元一瓶，淡咖啡色

B.Wahaha YouYou milk tea,Four yuan a bottle of,Light coffee color

　　实验过程：

The experiment process:

　　16：50，记者分别将两种奶茶倒入透明玻璃杯中，以普通奶茶瓶盖为量器，每种奶茶中分别倒入一瓶盖陈醋，并轻轻搅拌。加入陈醋后，娃哈哈呦呦奶茶很快出现了絮状物，而街头店铺所售原味奶茶却没有出现变化。

16:50,Reporter respectively two milk tea into a transparent glass,In ordinary milk tea bottle cap for measure,Each milk tea, into a bottle cap mature vinegar,And gently stir.Join after mature vinegar,Wahaha YouYou milk tea soon appeared floc,And the street shops sell milk tea taste but there is no change.

　　17：10左右，记者再次观察加过陈醋的奶茶发现，娃哈哈呦呦奶茶杯中从上到下布满了絮状物，体积较大，十分黏稠，搅动时有明显的触感；而街头店铺所售原味奶茶几乎没有什么变化，只在表面有少量不太明显的絮状物。

17:About 10,Reporter observed again with a mature vinegar, found,Wahaha YouYou milk tea cup from top to bottom was full of floc,Volume larger,Very sticky,Agitation is obvious sense of touch;And the street shops sell milk tea taste almost no change,Only in the surface has a few not quite clear floc.

　　为了对比，记者又将一盒蒙牛纯牛奶倒入另外一个玻璃杯中，同样向牛奶中加入一瓶盖陈醋。这时，记者发现，纯牛奶中刚加入陈醋，就迅速出现了咖啡色絮状物。几分钟后，这些絮状物又变成了一个个咖啡色凝结颗粒，有麦粒大小，悬浮在白色的牛奶中，不过始终没有出现分层。

In order to contrast,The reporter also will be a box of Mongolian cow pure milk into another glass,The same to milk to add a bottle cap mature vinegar.At this time,Reporter discovery,Pure milk just joined mature vinegar,Quickly appeared coffee floc.A few minutes later,These floccule and became a coffee coagulation particle,A kernel size,Suspended in the white milk,But never appear statified.

　　实验结果：娃哈哈呦呦奶茶变化明显，凝结絮状物后液体所占比例较小；而奶茶店中购买的原味奶茶产生的絮状物最少，“几乎可以忽略不计”。

The experimental results:Wahaha YouYou milk tea change obviously,Condensation floc liquid after the proportion of smaller;And milk tea shop to buy milk tea flavor to produce floc at least,"Almost negligible".

走访：街头制杯奶茶，两三分钟即可 visit:Street cup milk tea,Two or three minutes

　　实验表明，街头店铺所售奶茶“几乎没有变化”，那么其又是如何制作的呢？18日上午，记者在洛阳师范学院附近商业步行街走访发现，街头售卖各式奶茶店铺多达五六家，这还不算兼卖奶茶的豆浆店、咖啡屋。记者粗略估计，该街有10余家经营奶茶的店铺，在这些店铺中，并未看到放置有鲜牛奶或者奶粉的迹象。

Experiments show that,Street shops sell milk tea"Almost no change",So it is how to make?18 the morning,Reporter in the luoyang normal college visit found near commercial pedestrian street,The street selling all kinds of milk tea shop as many as five or six home,This isn't and sell milk tea soya-bean milk shop/cafe.Reporter roughly,The street has more than 10 business milk tea shop,In the shop,do not see placed a fresh milk or milk powder signs.

　　“要一杯椰汁奶，打包带走！”一家奶茶店前围着几个女生，争着报出自己选好的奶茶饮品。奶茶店广告牌上宣传的饮品，有原味奶茶、双皮奶等10多个品种，在店员身后的柜子上摆满了诸如椰汁、苹果、哈密瓜等各种口味的奶茶原料。两个店员忙得不可开交，一个店员麻利地拿起一个崭新的塑料杯，从一个贴有奶茶标签的不锈钢圆桶里挤出一种乳白色液体，随后又分别从不同颜色的塑料桶中舀出一些粉状物，最后在塑料杯里倒上热水，加上塑料薄膜盖，上下摇匀。两三分钟后，6元一杯的椰汁奶茶就做了出来。

"Have a cup of coconut juice milk,Pack away!"A milk tea shop front wall a few girls,Emulatively quote us choose their own good milk tea drinks.Milk tea shop on the billboards publicity of drinks,Have taste tea/double peel milk and so on, more than 10 varieties,In the clerk behind on the cabinet of filled up with such as coconut juice/apple/Hami melon, etc. Various kinds of flavors of milk tea raw materials.Two clerk busy as a bee,A shop assistant brilliant picked up a new plastic cup,From a labeled milk tea label of the stainless steel barrel squeezed a milky white liquid,Then respectively from different colors in plastic drum bail out some powder content,Finally in the plastic cup pour hot water,Combined with plastic film cover,Shake up and down.Two or three minutes,6 yuan a coconut juice milk tea out to do.

专家：这个方法基本可行 experts:This method basic feasible

　　网上流传的鉴定奶茶是否含奶的方法是否可信？针对此事，记者采访了洛阳师范学院化学系的刘丰博士。刘丰认为，该实验“基本可行”。

Popular online identification whether milk tea with milk method is credible?At this,The reporter interviewed luoyang normal college of chemistry LiuFeng doctor.LiuFeng think,The experiment"Basic feasible".

　　河南科技大学食品与生物工程学院的易军鹏副教授也称，牛奶中含有蛋白质，醋酸会破坏蛋白质本身的空间结构，使蛋白质产生絮凝。实验中的牛奶出现絮状物，其实是牛奶中的蛋白质发生了化学反应，蛋白质分子空间结构被醋酸破坏，原来的链状结构变得更加松散，因此肉眼看上去像是“絮状物悬浮在杯中”。

Henan university of science and technology institute of food and biological engineering YiJunPeng associate professor also called,Milk contains protein,Acetic acid break down proteins itself space structure,Make protein to produce flocculation.The experimental milk appear floc,Is actually in the milk protein happened chemical reaction,Protein molecular space structure is acetic acid damage,The original chain structure become more loose,Therefore the naked eye looks like"Floc suspended in the cup".

　　据介绍，奶茶本身的pH值在6到7之间，加入醋之后，pH值发生变化。当pH值低于4的时候，蛋白质就会出现絮凝。

According to introducing,Milk tea itself in the pH value between 6 to 7,Add vinegar after,PH value change.When the pH value less than 4 time,Protein will appear flocculation.

　　“若反应时间过长，絮状物会消失。”易军鹏说，在一定情况下，蛋白质分子空间结构会恢复原状。此外，醋并非只与蛋白质发生反应，也有可能与奶茶中的其他成分发生反应，产生絮状物。因此，“用食醋鉴定奶茶中是否含奶，只是基本可行，并不能完全保证奶茶中含奶”。

"If the response time is too long,Floc will disappear."YiJunPeng said,In certain circumstances,Protein spatial structure will restore to the original.In addition,Vinegar is not only with protein reaction,It is possible to milk tea in the other components of the reaction,Produce floc.therefore,"Use vinegar appraisal whether milk tea with milk,Just basic feasible,And cannot guarantee milk tea contains milk".

　　“作为一个生活小常识，网上流传的方法很有参考价值。”洛阳市工商局老城工商分局消保科科长姚拴龙说，这种方法“有道理有科学依据”，但只能作为一个参考，不能作为判定产品是否合格的法定依据。

"As a living little common sense,Online popular method is a reference value."Luoyang city industrial and commercial bureau commerce substation disappear is protected coco long YaoShuanLong said,This method"Reasonable have scientific basis",But only as a reference,Can not be used as decision product is qualified legal basis.

　　洛阳市工商局消保科科长王红霞也认为，这种方法不能作为法定依据。“工商质检部门有专业试剂，能检验出奶茶是否含蛋白质，但是对于网上流传的检验方法，工作人员不能保证其可靠性。”王红霞说。(大河报见习记者曹杰实习生陈龙文图)

Luoyang industrial and commercial bureau disappear is protected coco long WangGongXia also think,This method can be used as the legal basis."Quality control department and commerce have professional reagent,To test whether the tea with milk containing protein,But for online popular testing method,Staff cannot guarantee its reliability."WangGongXia said.(The river to trainee reporter intern Chen cao jie wen diagram)
