“…If the possibility of an additional concentration step is considered, according to the best knowledge of the authors, possible processes successfully applied for concentration of carotenoids from oils, are: adsorption chromatography (Baharin et al, 1998), membrane filtration (Darnoko and Cheryan, 2006), and molecular distillation (Batistella et al, 2002). In the first process, organic solvents (mostly Hex and IPA) are involved and hence the process cannot be labelled green and does not represent an alternative to the Hex:IPA process.…”

Sunflower oil (SF) and its methyl ester as well as supercritical fluid (SC-CO2+ 5 wt% EtOH) have recently been shown as potential green solvents which could substitute traditional organic solvents. This study investigates the economic feasibility of using these green solvents to extract astaxanthin (ASX) from shrimp processing waste. The feasibility of commercial use of the green solvents under plausible process conditions is compared to extraction with a mixture of hexane: isopropanol (Hex:IPA). The process flowsheets describing these processes were modelled by means of SuperPro Designer and Aspen Plus. The highest ASX extraction yield was achieved using Hex:IPA (26.4 kg/year), the lowest yield using SC-CO2+ 5 wt% EtOH (12.8 kg/year). The cost of producing pure ASX for these processes was about 0.6 and 0.82 $/mg of ASX, respectively. The concentration of ASX obtained by the extraction processes with SF or the methyl ester of SF (ME-SF) was 2.5 and 153 ppm with a production cost of 0.06 and 0.16 $/mg of ASX, respectively. In addition, shrimp feed production was considered as a feasible application of the low concentration ASX obtained by SF extraction. A combination of ASX extracted with SF and synthetic ASX yielded a shrimp feed 2 production cost comparable to the current market price. The calculated feed pricebased on the ASX production cost of the other green processes, ME-SF and SCFE, resultedin a significantly higher production cost.

“…Batistella et al (2002) proposed an approach to recover carotenoids, valuable pigments for the food industry, and biodiesel from palm oil by means of suitable techniques. Jatropha curcas oil, a non-edible vegetable oil, has been considered as a potential alternative feedstock for biodiesel production.…”

“…For example, deodorizer distillate of vegetable oils; palm oil for obtaining tocotrienols and tocopherols; oil of rice for the oryzanol recovery; monoglycerides concentration; carotenoids recovery from palm oil; heavy petroleum characterization, and herbicides. (8,29,47,48,49,50) Molecular distillation is often used to separate or purify high-boiling materials that decompose, oxidize, or polymerize at elevated temperatures. (51) This process can be considered for industrial uses if both distillate and residue are high value-added products.…”

Crude palm oil contains approximately 1% minor components, including carotenoids and vitamin E (tocopherols and tocotrienols), which contribute to the stability and nutritional properties of palm oil. Palm oil is considered one of the best sources of vitamin E. The vitamin E content in palm oil is unique because it is composed of tocotrienols rather than tocopherols. Palm fatty acid distillate (PFAD) is the volatile organic material recovered as a valuable by-product in the deodorization of palm oil. Several processes have been proposed for recovering tocopherols and tocotrienols from PFAD. For this separation process, it is necessary to develop a processing procedure to extract the valuable tocotrienols and other minor components from PFAD using molecular distillation. Molecular distillation occurs at low temperatures and reduces the problem of thermal decomposition. High vacuum also eliminates oxidation that might occur in the presence of air. The rate of evaporation is controlled by the rate at which the molecules escape from the free surface of the liquid and condense on the condenser. The effects of feed-flow rate and temperature of distillation on extraction of minor components from PFAD are based on concentrations, distribution coefficients, and relative volatilities. The separation of tocotrienols from PFAD approached maximum values at low temperatures and fell drastically as temperature increased. For the optimum conditions for the extraction of tocotrienols with high yield and purity, it is necessary to determine the effect of processing variables on the extraction of minor components (i.e., tocotrienols, a-tocopherol) from the PFAD in terms of concentrations in the liquid and vapor phases, to reveal the behavior of target components in the evaporation process, and to determine the evaporation and volatility properties of tocotrienols and other minor components from PFAD.
