ABSTRACT

Alaska Fisheries
Development Foundation continued efforts to fully utilize
Alaska's groundfish resources. Two tasks were incorporated
into the project: The first was the investigation of the
use of groundfish frames to produce a high quality protein
raw material for the food industry; and secondly to complete
an ongoing project to develop a machine vision system
to detect groundfish bones and parasites during the manufacture
of fillets. The objective of this project was to
continue research to recover additional usable fish flesh
from filleted groundfish carcasses, and develop and test
improved techniques for detecting bones and parasites
in groundfish fillets. A system was to be developed and
tested which can segregate defective product while allowing
defect-free product to pass without being handled. The
non-fillet flesh recovery portion of the project was successful
and resulted in the sale of some non-fillet flesh volumes
which would have gone directly to the waste stream. The
raw material extraction was successful and both yields
and quality were improved during the course of the project.
The bone and parasite removal portion of the project was
not successful from the standpoint of answering industry
problems. The new detection technique continues to show
promise on a research level and the process has been patented
by the University of Alaska Fairbanks. During the
by-product utilization portion of the project, primary
production of mince from frames was completed with evaluations
of the product conducted by a laboratory and various customers.
Three secondary products were developed and evaluated
through a focus group. One final product was test marketed
within-store demonstrations and fully developed point-of-sale
material. Increased recovery in Alaska groundfish
processing is feasible through the use of frame mince.
For high volume groundfish processors this increased recovery
seems to be sound from an economic perspective.
