【阿斯巴甜 原料药湖北厂家】详细说明
 阿斯巴甜(AsPartame)
 
天冬氨酰苯丙氨酸甲酯
别名阿司帕坦、阿斯巴坦,甜味素,食品添加剂国际编码 : E951,化学名称为L-天冬氨酞-L-苯丙氨酸甲酯(APM=L-aspartyl-L-phenylalanine methyl ester),是一种非碳水化合物类的人造甜味剂。
含量:99% 以上
包装(http://www.chemdrug.com/sell/99/)25公斤纸板桶
性状 :白色结晶粉末,无臭,有强烈甜味,甜度为蔗糖的100-200倍,甜味阈值为0.001-0.007%。微溶于水。热稳定性差,若用于需高温灭菌处理的制品,应控制加热时间不超过30s。25℃时等电点的pH值为5.2。微溶于水,约1g/100mL;乙醇,0.26mg/100mL。0.8%水溶液的pH值为4~6.5。在水溶液中不稳定,易分解而失去甜味。
ADI  0-40mg/kg(FAO/WHO,1994)。
代谢  本品进入机体内很快就分解为苯丙氨酸、天冬氨酸和甲醇,经正常途径代谢,排出体外。
分子式C14H18N2O5,相对分子质量294.31
性质:阿斯巴甜在高温或高pH值情形下会水解,因此不适用需用高温烘焙的食品。不过可藉由与脂肪或麦芽糊精化合提高耐热度。阿斯巴甜在水中的稳定性主要由pH值决定。在室温下,当pH值为4.3时最为稳定,半衰期约为300天。当pH值为7的环境下,其半衰期则仅有数天。然而大部分饮料的pH值都介于3至5间,所以添加在饮料中的阿斯巴甜均很稳定。但当需要较长保存期限时,像是自动饮料机的糖浆。阿斯巴甜会和其他较为稳定的甜味剂混合使用,例如糖精。用于粉状冲泡饮料时,阿斯巴甜的氨基会和某些香料化合物上的醛基进行梅勒反应,导致同时失去甜味和香味。可以缩醛来保护醛基避免此状况发生。
2主要用途
 
用途:是一种天然功能性低聚糖,不致龋齿、甜味纯正、吸湿性低,没有发黏现象。不会引起血糖的明显升高,适合糖尿病患者食用。我国规定可用于糕点、饼干、面包、配制酒、雪糕、冰棍、饮料、糖果、用量按正常生产需要。

Aspartame
Alias A Spartan, a Spartan, sweeteners, food additive International Code: E951, chemical name is L- aspartic phthalocyanine -L- phenylalanine methyl ester (APM=L-aspartyl-L-phenylalanine methyl ester), is a kind of artificial sweetener non carbohydrate agent.
Content: 99%
The 25 kilogram cardboard packaging
Properties: white crystal powder, odorless, has a strong sweet taste, sweetness is 100-200 times that of sucrose, sweetness threshold for 0.001-0.007%. Slightly soluble in water. Poor thermal stability, if used for products need high temperature sterilization treatment, heating time should be controlled less than 30s. 25 ℃ isoelectric point of pH 5.2. Slightly soluble in water, ethanol, 0.26mg/100mL is about 1g/100mL. 0.8% aqueous solution pH value of 4~6.5. Not stable in aqueous solution, easy to decompose not sweet.
ADI 0-40mg/kg (FAO/WHO, 1994).
metabolism of this product into the body quickly into phenylalanine, aspartic acid and methanol, the normal way of metabolism, excretion.
The molecular formula C14H18N2O5, relative molecular mass 294.31
Properties: Aspartame in high temperature or high pH value condition of hydrolysis, so it can not be used for baking food. But with fat or maltodextrin improved heat resistance. Aspartame in water stability is mainly determined by pH. At room temperature, when the pH value was 4.3 of the most stable, the half-life of about 300 days. When the pH value is 7 of the environment, its half-life is only a few days. However, most beverage pH values ranged from 3 to 5, so add in beverages aspartame are very stable. But when the longer retention time, like vending syrup. Aspartame and other relatively stable sweeteners such as saccharin mixed use. For powdered beverage brewing, aldehyde aspartame amino and certain spices compounds on the Mailer reaction, leading to lose both sweetness and aroma. To protect the aldehyde acetal can avoid this situation occurs.
The 2 main purposes of editing
