Embodiment 1
[0026] A preparation method of linseed oil microcapsules, comprising the following steps:
[0027] 1) Extraction of linseed oil by enzymatic hydrolysis: take 100g of linseed, after crushing, mix linseed with water at a mass ratio of 1:4, stir for 30-50 minutes, adjust the reaction temperature to 50-60°C, and use NaOH solution Adjust the pH to 8.5, add alkaline protease with a mass percentage of 2.0% (based on the total mass of the substrate), react for 4.5h, then adjust the temperature to 40-50°C, adjust the pH to 4.5-5.5 with HCL, add Composite cellulase with a mass percentage of 1.0-1.5% (based on the total mass of the substrate), the enzymolysis time is 4-5h, centrifuged at 3200rpm to obtain free oil 1, emulsion, hydrolyzate and slag , and then the obtained emulsion is subjected to secondary centrifugation to obtain free oil 2, and free oil 1 and free oil 2 are combined to form linseed oil, and the oil yield of linseed is 81.67%. ;
[0028] 2) Prepare the water phase: add...
Embodiment 2
[0037] A preparation method of linseed oil microcapsules, comprising the following steps:
[0038]1) Extraction of linseed oil by enzymatic hydrolysis: Take 150g of linseed, after crushing, mix linseed with water at a mass ratio of 1:5, stir for 40-60 minutes, adjust the reaction temperature to 55-65°C, and use NaOH solution Adjust the pH to 9.0, add alkaline protease with a mass percentage of 2.0% (based on the total mass of the substrate), react for 5.0 hours, then adjust the temperature to 50-60°C, adjust the pH to 5.0-6.0 with HCL, add Composite cellulase with a mass percentage of 1.2-1.7% (based on the total mass of the substrate), the enzymolysis time is 4.5-5.5h, centrifuged at 3500rpm to obtain free oil 1, emulsion, hydrolyzate and material Slag, then the obtained emulsion is subjected to secondary centrifugation to obtain free oil 2, and free oil 1 and free oil 2 are combined to form linseed oil, and the oil yield of linseed is 82.17%. ;
[0039] 2) Prepare the wate...
Embodiment 3
[0045] A preparation method of linseed oil microcapsules, comprising the following steps:
[0046] 1) Extraction of linseed oil by enzymatic hydrolysis: take 200g of linseed, after crushing, mix linseed with water at a mass ratio of 1:6, stir for 50-70 minutes, adjust the reaction temperature to 65-70°C, and use NaOH solution Adjust the pH to 9.0, add alkaline protease with a mass percentage of 2.0% (based on the total mass of the substrate), react for 6.0 hours, then adjust the temperature to 55-65°C, adjust the pH to 4.0-6.0 with HCL, add Composite cellulase with a mass percentage of 1.5-2.0% (based on the total mass of the substrate), the enzymolysis time is 5-6 hours, centrifuged at 3500rpm to obtain free oil 1, emulsion, hydrolyzate and slag , and then the obtained emulsion is subjected to secondary centrifugation to obtain free oil 2, and free oil 1 and free oil 2 are combined to form linseed oil, and the oil yield of linseed is 82.21%. ;
