Color is an important quality criteria for shrimp. Higher color more uniform color of cooked shrimp deliver premium products to the consumer. Astaxanthin is the most abundant pigment in most crustaceans, it is not produced by de novo synthesis and shrimp must acquire astaxanthin through their diet. Shrimp can bio-convert canthaxanthin and beta-carotene to astaxanthin, but this process is energy demanding since both canthaxanthin and beta-carotene are less efficient pigments in shrimp. Pigments are required for optimum nutrition of shrimp (anti-oxidant function, pigmentation and colour, photoprotection, pro-vitamin A).
