Why fish maw becomes thin and gel lacked after cooking?

Fish maw contains rich gel content which can be easily get melted if the cooking time is too long and the heat is too strong. We should pay attention to the control of soaking and cooking time and the heat temperatures. Avoid using hot water for soaking or cooking with strong heat in order to shorten the processing time. This will lead to loss of fish maw’s gel content.

Is older fish maw or fish maw having prolonged exposure to sunshine better in quality?

There is a saying that the older is the fish maw, the better is the quality. In fact, the length of storage does not affect the therapeutic value of fish maw. However, if the fish maw has been stored for a long time and exposed to long time sunshine, its texture will become stiffer and its golden yellow colour turns darker, that makes it look more appealing to customer. Moreover, its completely dry body can give bigger expandability after soaking.
