To improve the head rice yield and taste quality of indica rice,indica brown rice was treated by humidification and conditioning.On the basis of single factor test,response surface method was used to optimize the process,and the effect of humidification and conditioning treatment on rice quality was analyzed.The results showed that the optimal process parameters were water addition 2.5 g,treatment time 36 h,and treatment temperature 25 ℃.Under these conditions,the head rice yield of indica rice was 50.80%.Compared with untreated,the elasticity,adhesiveness,cohesiveness,and adhesion of the indica rice produced by humidification and conditioning treatment were improved,while the hardness and chewiness were decreased,and the palatability of the rice were improved.The taste value of the brown rice after roughening was above medium,while the untreated group was only medium.
