Abstract: Dry chestnut kernel with good color takes an especially important position in the chestnut processing, so color- protecting technique plays an important role in the processing. Through response surface analysis experiment, combining sensory evaluation for the chestnut kernel by different concentration reagents, the results showed that dipping in the mixed liquid of 0. 54% VC, 0.86% citric acid and 1.013% sodium chloride for 30 minutes are the optimum conditions.

Key words: chestnut kernel, color protecting, response surface analysis
