Abstract: This paper introduced the process of compound health beverage, which used Passiflora caerulea Linn. as the main material,and fresh carrot juice, milk powder and vitamins were added. The beverage is of good taste,special flavor,and stable quality. The best formula of health drink was defined by using orthogonal design. The results showed that Passiflora caerulea Linn. juice 10%,carrot juice 6%,milk powder 5%,casein 1.2%,sugar 6.25%,vitamins and mineral material 0.1%,stabilizers 0.3%, lemen acid 0.2% were optimal.

Key words: Passiflora caerulea Linn, orthogonal design, quality, evaluation
