“…carotenoid content was determined by measuring extract absorbance and expressing carotenoid content as astaxanthin equivalents using the observed extinction coe$cient, 2044, for pure astaxanthin in chloroform. The observed extinction coe$cient was in the range 1700}2300 as reported by Chen and Meyers (1984) for various organic solvents. Moreover, the absorbance spectrum of astaxanthin in chloroform showed a broad single peak corresponding to the "ndings of Lambertsen and Braekkan (1971); (astaxanthin in ethanol) and Christophersen et al (1989) (astaxanthin in n-hexane).…”

“…In a similar study, Sachindra and Mahendrakar () extracted carotenoids from shrimp waste ( P. indicus ) by using vegetable oils and concluded that sunflower oil was the best for extraction (26.3 µg/g). Chen and Meyers () showed that the utilization of vegetable oil gave higher carotenoid yield than fish oil. Krichnavaruk Shotipruk, Goto, and Pavasant () used vegetable oils as cosolvents for supercritical carbon dioxide extraction of astaxanthin from Haematococcus pluvialis and showed that soybean oil and olive oil (cosolvents) increased the carotenoids yield by about 30% and 10%, respectively.…”

Extraction of carotenoids from crustacean wastes was optimized in this research by the response surface methodology via organic solvent extraction (OSE) and vegetable oil extraction (VOE). Among the solvents, acetone and sunflower oil had the highest amount of carotenoid yield. The OSE and VOE were optimally applied to extract crab wastes by a solvent ratio of 4:1 (v/w) when the extraction was repeated 5 times (9.777 µg/g) and the oil to waste ratio was 5:1 at 78°C in 95 min (0.372 µg/g), respectively. The optimal conditions for extracting shrimp wastes were at a solvent ratio of 6:1 (v/w) by repeating the extraction 4 times (81.798 µg/g) and the oil to waste ratio was 5:1 at 40°C in 180 min (5.553 µg/g), respectively. Results revealed that the extraction of carotenoids by the OSE method is more efficient than the VOE method, and the amount of carotenoid yield in shrimp wastes is higher than crab wastes. Practical applications Shrimps and crabs are one of the most important natural sources of carotenoids among crustaceans. Crab and shrimp wastes could be used as the cheapest raw materials for carotenoid recovery, and also as an alternative to synthetic carotenoids. The recovery of these valuable components from the waste could improve the economy for crustacean processors and minimize the pollution potential of these wastes.

a b s t r a c tThis paper discusses the overall energy consumption and greenhouse gas emissions when extracting pigments and producing hydrogen from Spirogyra sp. microalga biomass. The energy evaluation from the biomass leftovers was also included in this work. The influence of the functional unit and different allocation criteria on the biorefinery assessments is also shown. The study consists of laboratory tests showing Spirogyra sp. growth, harvesting, drying, pigment extraction and fermentation by Clostridium butyricum. Electrocoagulation and solar drying were tested and compared to conventional centrifugation and electrical dewatering in terms of their energy consumption for harvesting and dewatering, respectively. To discuss the biorefinery viability, the pigments and biohydrogen (bioH 2 ) retail costs are considered against operational costs according to electricity needs. The low yield of biochemical hydrogen and the high energy requirements for the pigment extraction were identified as main topics for further research. This research hopefully contributes to highlight the importance of energy and emission balances in order to decide on feasibility of the biorefinery.
