Effects of concentrate and storage condition on fatty acid in alga Chlorella pyrenoidesa paste

The effects of concentrate (centrifugation, and flocculence by chitosan/sodium alginate mixture and alum) and storage condition (room temperature, cool, and frozen) on content of lipid and fatty acids in alga Chlorella pyrenoidesa paste were studied. The lipid content of the microalgae was found 23.... Full description

descriptionThe effects of concentrate (centrifugation, and flocculence by chitosan/sodium alginate mixture and alum) and storage condition (room temperature, cool, and frozen) on content of lipid and fatty acids in alga Chlorella pyrenoidesa paste were studied. The lipid content of the microalgae was found 23.38% in the centrifugation group, 14.12% in flocculence by chitosan/sodium alginate mixture group and 4.17% in alum group, significant differences among the three groups (P<0.05). The same fatty acids, predominantly 16:0, 16:1 and 20:5n-3, were observed in the alga paste through the experiment, whereas there was different content of the fatty acid, the poly-unsaturated fatty acid (PUFA) of 38.55% in the alum group, equal to about 76% in the centrifugation group (50.87%) and to 74% in the chitosan/sodium alginate mixture group (52.23%). However, the content of saturated fatty acid (SFA) in the alum group (31.74%) was found to be 1.6 times in the centrifugalization group (20.33%) and 1.7 times in the chitosan/sodium alginate mixture group (19.07%). The profile and contents of the main fatty acids in the microalgae paste were no significant differences under the room temperature (14.5-18.5 degree C) for 3 weeks, 4 degree C for 8 weeks and -24 degree C for 6 months. However, the content of 20:5n-3 was decreased from 41.81% to 39.50% and PUFA from 50.87% to 47.84% and the content of the mono-unsaturated fatty acid (MUFA) was increased from 27.54% to 30.20% in the microalgae paste stored in -24 degree C for a year.

abstractThe effects of concentrate (centrifugation, and flocculence by chitosan/sodium alginate mixture and alum) and storage condition (room temperature, cool, and frozen) on content of lipid and fatty acids in alga Chlorella pyrenoidesa paste were studied. The lipid content of the microalgae was found 23.38% in the centrifugation group, 14.12% in flocculence by chitosan/sodium alginate mixture group and 4.17% in alum group, significant differences among the three groups (P<0.05). The same fatty acids, predominantly 16:0, 16:1 and 20:5n-3, were observed in the alga paste through the experiment, whereas there was different content of the fatty acid, the poly-unsaturated fatty acid (PUFA) of 38.55% in the alum group, equal to about 76% in the centrifugation group (50.87%) and to 74% in the chitosan/sodium alginate mixture group (52.23%).
