Title: Study on the Extraction Process of Soybean Meal Protein Isolate
Abstract: Alkali-Extraction and Acid-Precipitation were used to extract separation protein from soybean meal.With protein extraction rate as indicator,based on the results of single factor test,the orthogonal design was employed to optimize the extraction technology and its parameter about protein isolated from soybean meal,and its functional properties were analysised,such as solubility,emulsifying capacity,stability of the emulsion and foaming stability.The results showed that the optimum extraction parameters were: temperature of extraction 60 ℃,the extracing time 60 min,the ratio of solid and liquid 1∶20 and pH 8.5.According to this,protein extraction rate was 84.2 %.And the protein had a good solubility,emulsifying capacity,foaming capacity and stability of the emulsion.
