Embodiment Construction

[0012] The present invention will be further described below.

[0013] A process for processing channel catfish quick-frozen fish fillets, the process comprising:

[0014] (1) Raw material acceptance and temporary maintenance. Select 500-1000g / piece of fresh fish from cage culture in freshwater deep reservoirs. They have spots and beards unique to channel catfish. They are slightly narrow and long, without deformation symptoms. More than 1 / 2 of the volume, the water temperature in the holding pool is controlled at 14-18°C (15°C in this embodiment), and sufficient oxygen is guaranteed.

[0015] (2) Bloodletting and slaughtering. Use a knife to cut the gills of the fish, cut off the gill artery, let the blood flow out along the tip of the knife, immediately put it into a clean pool, keep stirring, let it swim and breathe fully, let the blood drain until death, time 20- For 40 minutes (the present embodiment is 30 minutes), the amount of slaughter of fish in every pond is no m...

Abstract

The present invention discloses one kind of fast frozen white delicious fish fillet of spotted forked-tail Leiocassis longirostris and its production process. The production process includes the steps of temporarily raising, killing to eliminate blood, slicing, eliminating skin, trimming, soaking to sterilize, loading into tray and quick freezing, grading, coating with ice, packing, etc. The production process features complete elimination of blood, low temperature of fish fillet in icy water at 0-4 deg.c, soaking fish fillet in ozone icy water and ultralow temperature quick freezing at below -35 deg.c. The production process has high fish fillet yield and less nutrient loss, and the produced fish fillet is white, translucent and delicious.
