Aspartame (L-aspartyl L-phenylalanine methyl ester) referred to as APM, foreign trade names commonly used Nutrasweet, domestic trade names protein sugar, sweetness is about 200 times that of sucrose, is a high safety dipeptide sweetener, the United Nations Food Additives Committee included it in the A (1) level. 1981 by the U.S. FDA approval after rapid popularization, now the world has 50 It is now approved for use in more than 50 countries and regions worldwide. The recommended ADI value is 40 mg/kg, which is effectively an unlimited use. The US is the largest consumer of aspartame, with APM accounting for 90% of the US domestic sweetener market. However, the high price prevents its rapid diffusion in developing countries.
The chemical name of Alitame is N-(2,2,4,4,-tetramethyl-3-thia-cyclobutyl)-L-aspartyl-D-alaninamide (3), another dipeptide derivative in sweeteners. It is 2000 times sweeter than sucrose and was developed in 1979 by Pfizer Inc. Allyl sweet is heat stable and can be used in baked goods; it is also pH stable, non-toxic and odourless. It is widely used in the food industry and was included in the additive standard in China in 1994.
Sucralose is a sugar molecule in which the three hydroxyl groups are replaced by chlorine atoms. Its sweetness is 400-800 times that of sucrose. It was first patented in 1976 by Tate & Lyle in the UK and launched on the market in 1988 and approved by JECFA in 1990. Its advantages are that it is non-toxic, has no side effects, is thermally stable and is more stable in the baking process than Allyl Sweet. The sweetness is pure and has no bitterness or other strange tastes like cane sugar. It is not only harmless to the teeth, but also prevents dental caries, and does not produce heat, so it is a low-calorie sweetener.
Acesulfame is an oxythioacridone compound, the actual use of potassium salt, so called Acesulfame-K (AK sugar), sweetness is 200 times that of sucrose, good thermal stability, calorific value of 0. Taste quality is better than saccharin, with other high sweetness sweetener and sugar alcohols combined with a synergistic effect, the application range is wider than APM. More than 20 countries such as the United States, France, Britain and Germany have agreed to use it. The price is lower than APM and no safety problems have been found so far, so it has great development prospects.
Stevioside is extracted from the leaves of Stevia rebaudiana, a plant of the Asteraceae family from Paraguay and Brazil, and is 300 times sweeter than sucrose. The calorie value of stevioside, which has the same sweetness as sugar, is close to zero and was first introduced to Japan in 1971 from Paraguay, South America, where it originated, and was produced industrially in 1976. In Japan, it was first introduced from Paraguay, South America, in 1971, and industrialized in 1976. 30%-40% of sucrose has been replaced by stevioside, and in China, it was successfully introduced in 1976 and approved for use in 1986.
Thaumatin is a natural protein sweetener contained in the ripe fruit of the West African rainforest called Thaumato coccus Danielli Berth, known by its trade name Talin, which is 2,500 times sweeter than sucrose and is currently recognised as the sweetest plant in the world.
The composition of naturally occurring thaumatin is not entirely consistent and consists mainly of Thaumatin I, Thaumatin II, Thaumatin III, thaumat-inB and Thaumatin C. Its better flavour and stable performance have been greatly valued by many countries since its discovery, and has now been approved by dozens of countries in Europe and the United States, but has not yet been approved for use in China.
