The Chemistry Behind Crawfish and Shrimp Oil: Why Crustacean Scent Runs on Betaine, Not Trimethylamine
Crawfish and shrimp oil for trout is one of the most scientifically supported natural scent categories because it contains high concentrations of betaine, glycine, and other compounds found in real crustacean prey. Fish oil’s signature comes from trimethylamine. Crustacean tissue runs on an almost entirely different chemistry — dominated by glycine and betaine instead —…
