Abstract [en]

An efficient and environmentally sustainable extraction method is proposed for the enrichment of a high-value pigment, astaxanthin, from   a low-value raw material, shrimp waste. Ethanol at elevated temperature and pressure was used as a "green" extraction solvent. An experimental   design approach based on central composite design was used to   investigate the dependence of pressurized liquid extraction (PLE)  operating variables (pressure, temperature, extraction time) on the  recovered astaxanthin concentration from shrimp waste. The results show   that at a 95% confidence level, the most significant PLE operating   variables were extraction temperature and time. Extraction pressure had   only a minor effect on the astaxanthin recovery in the studied   experimental conditions. The maximum astaxanthin recovery obtainable by   PLE was calculated from the chemometrics results and then appraised by   experiments. Our results show astaxanthin yields of around 24 mg kg(-1)   shrimp waste. The reproducibility of the developed PLE method is good,   showing a relative standard deviation of 3.5% (n = 6) for astaxanthin.
