In this paper, several methods for detection of processed chestnut aging were studied. Results showed that some methods, including hardness, the centrifugal water quality, iodine absorbency and enzymatic hydrolysis, were suitable for aging detection of processed chestnut. Among them, the hardness method was the easiest but less of accurateness and the centrifugal water method was suitable for detecting the aging of amylase in processed chestnut. Iodine absorbency method could indirectly reflect the aging of samples and enzymatic hydrolysis method was somewhat complicated.
