Abstract:

Color is very important sensory feature of oranges and orange juice, which directly affects the choice of consumers. Color parameters of orange juice made from 94 kinds of orange samples collected from major orange production area in China were quantitatively determined using chromatic aberration method to establish the color database for color properties of orange juice in China. Statistical analysis indicated that color values of orange juice in China were over 36 points, which was higher and better than that of orange juice from USA and Brazil. An obvious difference in color values of orange juice from different varieties and production areas was observed, however, the color values of orange juice produced in different years didn t exhibit a significant difference (P > 0.05).

Key words: orange, juice color, quantitative evaluation
