Fish hydrolysate, in its simplest form, is ground up fish transformed into a liquid phase, where the cleavage of molecular bonds occurs through various biological processes. Raw material choice; either whole fish or by-products, depends on the commercial sources of the fish. In some cases, the fillet portions are removed for human consumption ...

Fish protein concentrate (FPC) - is a powder concentrate with medium level of protein (50-70%) and will contain some level of fat/oil (1-20%) in the powder form as well. [7] Fish protein isolate (FPi) - where the product contains less than 1% fat/oil and more than 90% protein. New manufacturing techniques are also producing hybrid FPi products ...
Recirculating aquaculture systems at the Virginia Tech Department of Food Science and Technology. Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control ...
Thereafter, the product can be stored as a liquid at 30–40% dry matter, or alternatively it may be spray dried or vacuum dried and further used as a food ingredient. [11] One hundred pounds (45kg) of material containing 60% protein will yield 100 pounds of aHVP, which contains approximately 40 pounds (18 kg) of salt.
