- 44. CONCLUSION Controlled hydrolysis can – Reduce environmental impact of wastes – Convert wastes into products for feed or food purpose – Offer different range of product compared to “classical” process FAO Expert meeting on fish technology 44 Agadir – Morocco, 24-28 November 2008
- 45. CONCLUSION By Comparison to traditional silage – Much more rapid – Less oil in final product – Better nutritional value (Trp and Lys increases) – More concentrated product – Oil can be separated and recovered (in case of fatty biomass) By comparison to “fishmeal” – Less energy consuming – Preservation of labile component (vitamin, antioxidant,…) – Food products FAO Expert meeting on fish technology 45 Agadir – Morocco, 24-28 November 2008
- 46. PERSPECTIVES Enzyme technology is now well established Versatile uses of enzymes is possible Food and Feed applications can be obtained Fish industry can achieved more added value fish fractions FAO Expert meeting on fish technology 46 Agadir – Morocco, 24-28 November 2008
