Regardless of the brine concentration, the highest
astaxanthin extractability appeared at pH 7.0, (Fig. 3b).
The maximum extractability of astaxanthin (0.480.07
mg kg1 mince) was observed for 1 M brine, and 12%of the total carotenoid content of the mince was solubilised.
Lowest extractability (0.030.01 mg kg1 mince)
was observed for 6 M brine, in which 0.8% of the total
carotenoid content was solubilised.
