Can pigs have artificial sweeteners?

1. Some amino acids on the human sweet receptor protein are replaced, resulting in great differences in the responses of humans and pigs to the same sweetener.

2. Carbohydrate sweeteners have similar sweetness to humans and pigs, so you can basically use oral taste to identify the sweetness. For example, sucrose has a sweetness of 1 for humans and a sweetness of 1 for pigs. The sweetness of lactose to humans is 0.33 and to pigs it is 0.146.

3. Non-carbohydrate sweeteners, such as aspartame, cyclamate, thaumatin, NHDC, etc., are very sweet to humans. However, because the corresponding receptor protein structure on pig taste buds is different from that of humans, resulting in These human sweeteners have no real effect on pigs at all. For example, the sweetness of thaumatin to humans is 100,000 (one hundred thousand times the sweetness of sucrose to humans), but for pigs, the sweetness of thaumatin is almost 0.

4. Saccharin sodium is an effective sweet source for pigs, but the response of pigs is much weaker than that of humans (sweetness for humans is 215, for pigs 3.34). Therefore, ordinary saccharin sodium is not very effective in attracting pigs. . (Think about it, everyone, the sweetness of saccharin sodium to pigs is only more than three times that of sucrose. Calculating that sucrose has an appetite-inducing effect of 3-5%, how much saccharin sodium must be added to have an effect?) Therefore, when selecting non-carbohydrate sweet sources in actual production, it is recommended to choose a sweetener that uses saccharin sodium as the main sweet source and undergoes specific flavor modification to remove the metallic aftertaste, thereby increasing the sweetness of saccharin sodium and ensuring the effectiveness of the sweet source. and sweetness efficiency.
