Yes In recent years, some manufacturers have used alginate as raw material to produce artificial jellyfish skin. The appearance of artificial jellyfish skin is similar to that of natural jellyfish skin, but it has no nutritional components of natural jellyfish skin. So it is very difficult to identify, especially in inland areas. There are two points in how to identify: 1. Look at the natural shape of the circle, with neat edges and no holes in the middle. Man-made edges are irregular, resulting in various shapes.

2. Look at natural colors. Jellyfish skin has different colors in different places, such as white and milky white, but the surface is moist and shiny without obvious red spots. Man-made. No.
