Solvent‐free enzymatic glycerolysis of marine oils

Abstract: Marine triglyceride oils (cod liver oil and oils from blubber of harp seal and minke whale)were reacted with glycerol using lipase as a catalyst at low temperature. A solventfree batch system with magnetic stirring was used. Solidification of the reaction mixture occurred, and a mixture of mono-, di-, and triglycerides was obtained in all cases. The recovered glyceride mixtures were solid at room temperature. The yield of monoglyceride (MG) and the fatty acid profile of the MG fractions were dependent on oil a… Show more

“…Under these conditions tallow, palm oil and palm stearin were converted to monoacylglycerols in yields of 90±95%. Similar reactions have been reported for palm oil, 62 camphor tree seed oil (a lauric oil, 63 ), cocoa butter, 63 marine oils, 64 olive oil, 65,66 soybean oil 67 and triolein. 68 Yamane et al 69 adapted the procedure to give high yields (90%) of diacylglycerols in a two-phase glycerolysis of hydrogenated beef tallow effected at 60°C (2 h), 55°C (4 h), and then 48°C for three days.…”

“…método, foram obtidos altos rendimentos de MAG (70-99%) utilizando diferentes meios reacionais. 29,41,43 Outro ponto crítico que precisa ser controlado é a temperatura de reação que deve ser mantida abaixo da temperatura do ponto de fusão do monoglicerídeo, como por exemplo, para sebo de boi, cuja temperatura de reação foi de 42 ºC fornecendo 72% 1(3) MAG usando lipase pancreática ou microbiana. 27 Um melhor desempenho do processo pode ser ainda obtido por meio do controle do teor de água do meio reacional, variando a polaridade do meio reacional (proporção entre triglicerídeos e glicerol) ou alterando a hidrofilicidade do suporte de imobilização da lipase.…”

“…This transesterification may be carried out by chemical or enzymatic means (Rubio-Rodríguez et al, 2010;Shahidi and Wanasundara, 1998).The former technique uses a chemical catalyst and the latter may use non-selective lipases or not, thereby giving a contribution for the concentration process Myynes et al, 1995). The chemical method involves a sodium ethoxide-catalyzed transesterification of the oil with ethanol, Typical processing temperatures for this stage of the process would be 80-90 °C.…”
