Abstract： |
A method for extracting carotinoid and edible glycerin from Dunaliella sallina is provided, which comprises the following procedures: optimized nurture of Dunaliella sallina, concentrate the sallina liquid with hollow fiber film method, centrifugal separation, dehydration and drying, extraction of carbon dioxide with super-critical method. The invention adds no chemical reagent in the extraction process, thus ensuring environment-friendly performance, low loss rate of Dunaliella sallina in the extraction process, high recovery rate of carotinoid and edible glycerin, simple process, low cost and suitable for large scale production. |
