Fish Protein Isolate by pH Shift

The demand for sh protein throughout the world is increasing faster than can be met with traditional resources. This demand has, in fact, led to overshing of many of the more traditional species and has required governmental interventions to prevent eradication of these species. In spite of the current bleak situation and the economic disruption that loss of sh stocks has caused in many parts of the world, there are still abundant sh that are underutilized, in the sense that they are not primarily directed toward human consumption. Furthermore, seafood processing generates large amounts of raw material that have either no use or low-value uses. These materials often contain high levels of proteins that are difcult to extract, but could nd uses for high-value applications, given an economical and efcient process.
