| Abstract: |
| Soybean oil and soybean protein both produced by enzymatic aqueous method were used as core material and wall material of oil powder, in the same time, adding compound emulsifier (ratio of monoglyceride to sucrose ester 1∶?1)and wall material maltodextrin to obtain a stable oil-in-water emulsion by constant temperature high speed stirring and high-pressure homogenization. The emulsion was spray-dried to obtain high oil and no oil leakage soybean oil powder. The optimal preparation conditions of soybean oil powder by enzymatic aqueous method were determined by response surface methodology as follows: maltodextrin 2.6%, emulsifier 1.2%, casein sodium 15.2%, solid content 35.3%, emulsification temperature 64.5?℃. Under these conditions, the soybean oil powder with 40.18% oil and 94.13% embedding efficiency was obtained, and it had good sensory properties, high degree of emulsification of restoration emulsion and high level of emulsion stability. |
