The protein in the lipid-mineral-rich carotenoprotein
has good amino acid composition with high amount of
glutamic acid (Table 4). Previous study also showed that
shrimp waste had high protein content with good amino
acid balance and glutamic acid was the abundant amino
acid in shrimp protein(15). Besides, this carotenoid-protein
complex can make carotenoid (mainly astaxanthin) more
stable than the carotenoid alone(6).
