问:
如何区分一个简单的蜡和黄油,其物理或化学性质。
吃火锅的朋友说在烹饪结束锅,一些投机商将石蜡而不是黄油,熔点几乎看不见,可胃大不同。
在外部材料的最终购买的也有这个问题,如何区分它。 ?

答:
首先看它是否是在包装上有制造商的网站,制作,接触,二是看到感受到的硬度。如果特别特殊的硬件,是断绝断绝恒定,一般是(加)石蜡;第三,在融化速度看。 20或30度摄氏的汤黄油wq融化,而石蜡做(底部饲料)融化缓慢,因为它的熔点相对较高,一般50-70摄氏度融化。

答:
有一个轻石蜡,而且也很难。奶油黄色,质地柔软。

答:
从原油中的溶剂精制,溶剂脱蜡或蜡冷冻结晶蒸馏所获分数记者脱蜡蜡膏,和溶剂脱油,然后从表精制或针引起结晶。也称为蜡晶形状。主要成分为正构烷烃,有个别支链烷烃和环烷烃侧链长的小乐队。为熔点和含油量的关键质量指标,前者表示,温度的能力,这表明纯度。精制加工按不同级别可分为全精炼石蜡,半精炼石蜡,粗3种。前两个广泛使用,主要用于粮食和其他商品,零部件和包装材料,烘烤容器的涂层材料,化妆品原料,用来保存水果,提高橡胶抗老化性和增加灵活性,电器元件,绝缘,精密铸造,蜡纸,蜡烛,复合纸。粗石蜡更主要是由于在火柴,纤维板,帆布帐篷等生产中使用的含油量。加入聚烯烃添加剂,其熔点增加,粘附性和灵活性的增加,广泛用于防潮,防水包装纸,纸板,某些纺织品,表面涂层和蜡烛生产。
身体会产生食用蜡什么危害?与中国包装资源综合利用委员会董金狮主任采访。据他介绍,石蜡在高温下长时间加热会分解成低分子化合物的数量。这种化合物将人们的呼吸道和胃肠系统,造成一些伤害。例如,许多人吃火锅时,往往会发现有腹泻的现象,一般认为是辣椒的结果。事实上,由于进食后肠胃蠕动,华张和腹泻石蜡也。

购买时代即将结束锅,消费者应注意三点:一是看包装不是制造商的网站,厂家名称,联络资料,这是非常重要的;第二,并不感到特别特别硬,切断了一不断中断,因此通常是添加石蜡;第三,黄油,预计在20到30度的温度底的做法,wq融化,而融化的石蜡是做相对缓慢。

How do I distinguish between paraffin and butter?

Question:
how to distinguish between a simple wax and butter, its physical or chemical nature.
eat hotpot friend said to the pot at the end of cooking, some profiteers put paraffin instead of butter, melting point almost could not see, can stomach the big different.
bought at the end of the outside material also has this problem, the how to distinguish it. ?

Answer:
first to see if it is there on the packaging manufacturer and third, look at the rate of melting. Twenty or thirty degrees Celsius in the soup butter is completely melted, while paraffin done (bottom feed) to melt more slowly, because of its relatively high melting point, generally 50-70 degrees Celsius to melt.

Answer:
there is a light paraffin, but also hard. Butter yellow, soft texture.

Answer:
derived from crude oil distillation fractions by solvent refining, solvent dewaxing or wax frozen crystal obtained press dewaxing wax paste, and then by solvent de-oil, refined drawn from sheet or needle-like crystal. Also known as wax crystal shape. Main components were n-alkanes, there are a small band of individual branched-chain alkanes and cycloalkanes with long side chain. Key quality indicators for the melting point and oil content, the former indicated that temperature capability, which indicated that the purity. Refined according to the different levels of processing can be divided into full-refined paraffin wax, semi refined paraffin wax, and three kinds of rough. Before a wider use of the two, mainly for food and other commodities, components and packaging materials, baking container coating materials, cosmetic raw materials, used in fruit preservation, and improve the rubber anti-aging properties and to increase flexibility, electrical components, insulation, Precision casting, wax paper, candles, paper in compound. Crude paraffin oil content of more due mainly used in the manufacture of matches, fibreboard, tent canvas, etc.. Adding polyolefin wax additive, its melting point is increased, adhesion and flexibility increase, widely used in moisture-proof, waterproof wrapping paper, cardboard, certain textiles, surface coating and candles production.
the body will produce edible wax what harm it? An interview with China Packaging Resources Comprehensive Utilization Committee Dong, director of the Golden Lion. According to him, the paraffin prolonged cooking at high temperatures will be broken down into a number of low-molecular compounds. The compound will peoples respiratory and gastrointestinal system, causing some harm. For example, many people eat hot pot, it often will be found to have diarrhea of the phenomenon, it is generally considered to be a result of pepper. In fact, after eating paraffin also because of gastrointestinal motility, Hua Chang and diarrhea.

buy pot at the end of the time expected, consumers should pay attention to three points: one is to look at the packaging is not a manufacturer site, factory name, contact details, this is very important; second, does not feel particularly special hard, breaking off a are constantly breaking off, so is usually added paraffin wax; third, butter is expected to do at the end of twenty to thirty degrees in temperature completely melted, and melted paraffin was done relatively slowly.
