Abstract: In recent years,the research and development of compound yogurt has become a trend. Oranges are rich in a variety of organic acids,which can regulate human metabolism,and dandelions are rich in minerals and vitamins that are beneficial to the human body. Using fresh milk as the main raw material and orange juice and dandelion juice as auxiliary materials,a health-care coagulated yogurt with the flavor of orange juice and dandelion juice is prepared. The effects of dandelion juice addition,orange juice addition,sucrose addition and starter inoculum on the quality of yogurt were investigated. Taking the sensory score as the evaluation index,a single factor test was carried out,and on this basis,an orthogonal test with four factors and three levels was carried out,and the optimal process parameters were obtained: 5% orange juice addition,10% dandelion juice addition,0.9% starter inoculum, 1% sucrose addition. The fresh orange dandelion-flavored yogurt produced under this condition has fine texture,sweet and sour taste,good quality and unique flavor,with sweet orange juice flavor and fresh dandelion juice flavor.
