Abstract:

In this study, the relationship between pectin content and quality characteristics of tomato powder from spray drying was investigated using tomato paste as the raw material. The yield of tomato powder, microscopic characteristics and color change of tomato power from tomato paste with different pectin contents were evaluated. Results indicated that the yield of tomato powder was proportional to the pectin content of tomato paste under the identical condition of spray drying. The color change of tomato power exhibited a similar trend from red to reddish yellow, which revealed the gradually increasing L value and b value, and the declining a value. Tomato power with various pectin contents could provide more uniform particle size distribution and better dispersion due to the enhancement of pectin content.

Key words: tomato paste, tomato powder, pectin content, quality
