Abstract: The optimum extracting conditions of protein in lotus seed was studied in this paper.The influences of the ratio of lotus to solution(W/V),pH,temperature and time on the extraction rate were investigated.On the basis of single factor test and the orthogonal test,the optimal working parameters were worked out.And considering the feasibility in industry,the optimum extracting conditions of protein are:lotus to solution ratio 1:25,pH11.0,40 ℃ and extracting for 3 h.The extraction rate reaches 86.45%.

Key words: lotus seed, protein, orthogonal test, extraction rate
