| Abstract: |
| Based on single factor experiment, the preparation conditions of Sacha Inchi protein by alkali extraction and acid precipitation were optimized by orthogonal experiment with extraction rate as index, and amino acid composition of Sacha Inchi protein was also analyzed. The results showed that the optimal extraction conditions of Sacha Inchi protein were obtained as follows: ratio of solid to liquid 1∶?30, alkali extraction time 2 h, alkali extraction temperature 70?℃, alkali extraction pH 9.0.Under these conditions, the extraction rate of Sacha Inchi protein reached 83.91%. The Sacha Inchi protein contained relatively complete amino acid composition and it was rich in essential amino acids. The Sacha Inchi protein was a kind of valuable vegetable protein resource. |
