Taking wild olive in Liangshan prefecture as raw materials,considering sugar liquid concentration,shading dose,and the acid concentration etc which have some effects on the process of the preserved-fruit wild olive,the orthogonal experiment results show that,in the test conditions within the limited scope,the primary and secondary sequence of the impregnation factors on the impregnation result effects is sugar liquid concentration shading dose acid concentration.The best dipping condition for liquid sugar is 45%,and shading dose of concentration of 0.01% is 4% and citric acid is 2%.
