2. Surimi byproduct
(1) Surimi
1. Minced fish is leached 2-4 times with chilled water to remove soluble components, mainly proteins and
blood, and then kneaded with sugar and polyphosphates and frozen into blocks
- Alaska pollock, big eye, croaker, threadfin bream, sardines, tilapia, mackerel, pacific whiting
1) Recent research trends
1. Temperature affects the conformation of myofibrillar proteins and can activate endogenous enzymes
2. Fish muscles from different species revealed similar responses to temperature
3. Modori is induced by endogenous thermal stable proteases activated at 50-70 ℃
4. Endogenous cysteine proteases have the most serious effect on texture, especially cathepsins and
heat-stable alkaline proteases
5. Food grade inhibitors and cystatins
⑴ Bovine plasma protein - Bovine spongiform encephalopathy (Cow madness disease)
⑵ Soybean protein
(3) Whey protein
(4) Egg white and potato protein – off-flavor and coloration, avian influenza
(5) Wheat flour
