In order to improve the lack of flavor and taste of the two citrus varieties of Owari and Miyagawa in Zhejiang， the Citrus Sinensis Osbeck or Newhall Navel juice according to different compounding schemes was added to expand Owari and Miyagawa. The conventional methods were used to determine the total phenolic， flavonoids， soluble sugars， VC， titratable acid， pH， soluble solids， suspension stability， volatile flavor ingredients after homogenization of different proportions of NFC citrus juice， and compared different combinations. The principal component analysis （PCA） and sensory evaluation were used to optimize the ratio of the complex citrus juice to the mouthfeel and flavor. The results showed that the addition of Citrus Sinensis Osbeck and Newhall Navel can effectively improve the physical and chemical indicators and nutrient index of Owari and Miyagawa. By sensory evaluation of NFC compound juices with different compound ratios， it can be seen that the combination of Miyagawa ∶ Citrus Sinensis Osbeck and the combination of Miyagawa ∶ Newhall Navel scored higher in sensory evaluation. In the Miyagawa ∶ Citrus Sinensis Osbeck compound combination， the two citrus scores were best based on 4 ∶ 1 compound sensory evaluation；in the Miyagawa ∶ Newhall Navel compound combination， the citrus was evaluated by 3 ∶ 2 excellent. According to the results of principal component analysis， the compounding scheme with higher comprehensive scores is Miyagawa： Citrus Sinensis Osbeck 3 ∶ 2， Miyagawa ∶ Citrus Sinensis Osbeck 7 ∶ 3， Miyagawa ∶ Newhall Navel 3 ∶ 2， Miyagawa ∶ Newhall Navel 7 ∶ 3， Owari ∶ Citrus Sinensis Osbeck 3 ∶ 2. The NFC citrus juice prepared by these compounding schemes has higher nutritional value， better flavor and better market prospects. Analysis of the volatile flavor components of fruit juices with different mixing ratios shows that there was no significant difference between the different mixing ratios of Miyagawa and Citrus Sinensis Osbeck， the mixing ratio of Miyagawa increase， difference depends on terpinen-4-ol and γ-terpinene. The difference between the ratio of Owari and Citrus Sinensis Osbeck was 2-hexenal. In different ratios of Owari ∶ Newhall Navel and Miyagawa ∶ Newhall Navel， Newhall Navel plays a significant role in compounding different ratios.
