Besides natural color and translucency, what other methods can be used to distinguish genuine fish maw from fake fish maw before it is soaked? The third point is that the veins are clearly visible.

Because synthetic fish maw is made by crushing broken fish bladders and pressing them into a single piece, which can be molded into various shapes (such as tubes, sheets, and open-edges) for higher prices, it lacks the neat, natural texture. Whether before or after soaking, the texture of synthetic fish maw is disorganized, with no discernible pattern or even suppressed to the point of being completely invisible. In contrast, the linear texture of genuine fish maw is clearly visible before soaking, and after soaking, the texture is incredibly clear, detailed, and profound! The picture shows the "Australian Premium Tubular King" sold by On Hing Hao, which features a distinct herringbone pattern, each line clearly defined.
