[0002] In the applicant's previous research, it was found that the content of sialic acid will decrease to a certain extent when the high-temperature sterilization treatment is carried out in a liquid environment. The viscosity of the liquid and the concentration of the contents have certain requirements, so the method of high temperature sterilization is irreplaceable in some application fields
The applicant also found that adding a certain amount of potassium sorbate can solve this problem, but not all application environments will add potassium sorbate, and potassium sorbate cannot satisfy all application concepts, so it is necessary to continue to expand the solution , to expand the application of sialic acid

Abstract
The invention relates to the field of food and cosmetics, in particular to a sialic acid-containing composition as well as a preparation method and application thereof. The composition is an aqueous solution, and the aqueous solution contains sialic acid and trehalose. The sialic acid and the trehalose have a synergistic effect, after the sialic acid and the trehalose are compounded, the problem that the content of the sialic acid in a sialic acid aqueous solution is reduced in the subsequent high-temperature sterilization treatment and the shelf life can be effectively avoided, the anti-saccharification effect of the composition is further enhanced, and the composition shows extremely high application value.
