Abstract:
This paper sampled 30 wheat varieties from 9 provinces, and the hardness and springiness of wet wheat gluten were investigated with texture analyzer. The results showed that there was a highly significant positive correlation between gluten hardness and chewiness, with hardness of TPA on 0.05 level. Also, gluten hardness showed highly significant correlations with gluten index, rough stable time, relative extensibility, swelling test value and ratio of penetrable light on 0.01 levels. High significant positive correlation between gluten springiness and gluten index, relative extensibility were also found on 0.01 levels. In addition, gluten springiness also showed clear correlations with swelling test value and toughness on 0.05 level. Therefore, the gluten hardness can be used to determine the strength of gluten and predicting the texture quality of dumpling wrapper.
