As a functional sweetener (Functional Sweeteners), neotame no adverse effects on human health, the regulation or play a useful role in promoting. It has been proposed in the United States early in December 1998 as a food sweetener Neotame cryogenic applications. It was July 9, 2002 review by the US FDA food additive allows application in all food and beverage. EU on January 12, 2010 formally approved its application, its designated code E961. People's Republic of China Ministry of Health Bulletin No. 4 of 2003 also formally approved neotame for the new food additives for all kinds of food production.
Sweet and pure, fresh and natural, and it is similar to aspartame, but security is high;
Sweetness, is about 8,000 times that of sucrose, aspartame and other low costs than sweetness;
Nutrients contained in easily absorbed by the body;
Low energy or no energy available for human consumption, diabetes, without caries, can promote the proliferation of Bifidobacterium;
Does not cause tooth decay, blood sugar fluctuations, the sweetener of choice for health-food products.
Under acidic conditions, neotame and aspartame having substantially the same stability. At neutral PH range or transient conditions such as high temperature, neotame to Biasiba sweet much more stable, which greatly expanded its application areas, such as the application in bakery products.
Neotame under normal storage conditions, dry powder with excellent stability, but the stability in aqueous solution has some limitations, the effects of temperature, pH, time and other factors affected its stability, there will be some degree of sweetness drop, at room temperature at (25 ℃) stability in aqueous solution, roughly: PH3.0 half-life of 78 days; half PH4.0 when 156 days; half PH4.5 when 208 days; when the 150-day half-life PH5.0 ; PH5.5 half-life of 112 days. Best PH value of 4.5. In view of this, the use of Neotame if used in conjunction with sugar or other sweeteners, can improve its stability.
Neotame has pure sweetness, in general or sugar-free drinks to replace some sweeteners neotame use, not only to obtain suitable sweetness and flavor of the product, Neotame is more characteristic of lower product cost.
The results show that in the beverage products, Neotame can replace 25% of the nutritive sweeteners or high intensity sweeteners can be kept close to the organoleptic properties.
Neotame has pure and sweet as sucrose, but there is rain after Neotame sweetness. Rely on intuition (tongue feel) assessment.
Neotame in the dry state, has excellent stability in powder form the finished product. In humidity conditions, the stability of neotame and PH value, temperature and time dependent. Neotame is suitable for batch production, the concentration of high temperature short time (HTST) sterilization and aseptic operation, the resulting final product Neotame has hardly changed.
In a particular application and flavor systems, Neotame can significantly extend and enhance the product's taste and aroma. Neotame in the actual application process, its amendments and certain characteristics of flavor, fragrance Product readjust the system and the amount or kind of sour agents. In the beverage powder, add Neotame can be reduced at least 20% of the amount of citric acid, without affecting the product's acidity.
A lot of research results show that neotame is suitable for all people, including children, pregnant women, breastfeeding women and patients with diabetes, including. Neotame is no need to use special PKU patients showed. Neotame can quickly metabolism in the body. The main metabolic pathways by enzymes produced by the body to make methyl ester hydrolysis, the last generation skimmed Zealand sweet and methanol. Compared to ordinary foods if the amount of methanol juice, vegetables, and vegetable juices, neotame the decomposition minimal. For example, the methanol content of tomato juice containing neotame beverages than 200 times. Neotame can be completely eliminated from the body with the urine and feces, do not accumulate in the human body.
