Abstract:

In order to increase the extraction yield of wheat flour water-extractable arabinoxylans and provide technical support for further research, this paper studied the effect of extraction temperature, extraction time and material-to-water ratio on the yield of water-extractable arabinoxylans. The Response Surface Methodology with 3 factors and 3 levels was adopted on the basis of single-factor experiments. The impact of each variable and their interaction on yield of water-extractable arabinoxylans were studied and the extraction parameters were optimized. The results showed that the optimized extraction conditions were obtained as follows: extraction temperature 46℃, extraction time 103 min, the ratio of water to material 1:9, and the yield was 0.689 % under the extraction condition.
