4. Soluble proteins in waste water streams are more difficult to recover
⑴ Membrane technology : the problem of membrane fouling
⑵ Selective recovery of different soluble proteins
5. Recovery of enzymes and bioactive components from surimi waste presents both a challenge and
an opportunity
6. Waste water treatment in the seafood industry
- The challenge is to determine whether the priority of the companies is to reduce the cost of waste
water treatment or to recover solids (protein), or both for use as a by-product
7. To develop environmental awareness among employees and to educate them not to waste
freshwater
⑤ Conclusions
- Waste use is an important issue for the seafood industry, particularly the surimi industry
- Pollock industry must move toward full use of what is harvested
- An equally important concern is whether waste use makes economic sense
- Harvesting and processing should be as fast as possible to ensure high production rates
- More profits could be made in the higher grade surimi
- It is important for companies to develop lone-range strategies for waste water treatment and
protein recovery
