Crisp meat tilapia is made crispy by feeding fava beans, this is because fava beans contain a substance called fava bean glycosides, which can stimulate the muscle fibers of tilapia to become tighter, thus making the meat crispy.
When farming crispy tilapia, you need to cook the fava beans and feed them to the tilapia, and after the tilapia consume the fava beans, the fava bean glycosides will be accumulated in their body, thus making their flesh crispy.
