Embodiment 1
[0026] Dissolve bovine serum albumin (500mg) in deionized water (10mL) to form a bovine serum albumin aqueous solution; dissolve NaCl (10mg) into a fluid chitosan hydrogel (10mL), and then pass Stir (500rpm) to disperse chitosan hydrogel evenly in soybean oil containing sorbitan oleate (20mg / mL) (V 水凝胶 :V 油相 =1:5) to form an oil phase containing NaCl; add bovine serum albumin aqueous solution and soybean oil containing NaCl to the reaction flask at a volume ratio of 3:1, and place it in a water bath (40°C); The probe is placed at the oil / water two-phase interface, and high-intensity ultrasonic radiation (200W / cm 2 , 10min); after the reaction, the reaction solution was cooled (10°C), centrifuged (1000rpm), and the lower sediment was washed (3 times), and finally a bovine serum albumin cross-linked membrane was obtained, which contained Soybean oil with NaCl as the core of the microcapsules. Under the optical microscope, the microcapsules are spherical or ellipsoidal; the av...
