09 and 90 compressed biscuits are made by high pressure and high temperature technology. They are crispy biscuits with unique taste. However, their compression mode and material composition are different, which leads to their differences.

First of all, 09 and 90 cookies are compressed differently. 09 biscuits are pressed by two rollers, and 90 biscuits are cut by a single roller pressing flat dough. This different compression method will affect the shape and density of biscuits, thus affecting the taste and texture of biscuits.

Secondly, 09 and 90 biscuits have different ingredients. When making 09 compressed biscuits, low-powder, skim milk powder and a certain amount of oil and sugar are widely used. This formula can make cookies easier to press and keep their shape intact. However, more starch and fat are added into the 90-compression biscuit, which makes the surface smoother and the taste crisper.

Summary:

Therefore, 09 and 90 compressed biscuits are different in specific manufacturing technology and material composition, which leads to their different characteristics in appearance, taste and texture. The specific choice of biscuits depends on personal taste and specific occasions.
