  • Method for producing cis-unsaturated fatty acid by recombinant lipase 1 (rCRL1)
    Patent number: 11685939
    Abstract: A method for producing cis-unsaturated fatty acid includes the operations below. (i) An oil-water mixture is provided, wherein the oil-water mixture includes 1 to 10 parts by weight of oil and 1 part by weight of water. (ii) 0.002 to 0.5 parts by weight of a recombinant Candida rugosa lipase 1 (rCRL1) is added into the oil-water mixture. (iii) The oil-water mixture is emulsified. (iv) The emulsified oil-water mixture is hydrolyzed and fatty acid is generated. (v) Oil-water is separated at a temperature of 55° C. to 65° C. and an oil phase layer is extracted. (vi) The cooling and filtering step is performed to obtain cis-unsaturated fatty acid.
