The solution of the present invention is: the Chinese chestnut no infested, that damage that will take puts into that concentration is in 2%-4% salt (NaCl) aqueous solution under the normal temperature, soaks 30-60 minute, pulls out then, inserts in the vacuum tank after drying to seal.
Adopt the Chinese chestnut of processing of the present invention, its freshness date can reach more than eight months, operated very simply, and expense is low, airtight container adopt sealed plastic bag or jar, make it to be easy to transportation and consumer and eat.Salt solution concentration that the present invention is used and soak time then can not reach the effect of described long-term preservation if be lower than lower limit, if brine concentration is higher than the upper limit, can make Chinese chestnut have saline taste, if soak time is higher than the upper limit, and then Chinese chestnut meeting swelling, damage.
Embodiment 1: 0.1 kilogram of salt is dissolved in 5 kilograms of water under the normal temperature, no fresh Chinese chestnut infested, that damage was soaked in this salt solution 30 minutes, be encapsulated into to vacuumize in the polybag after pulling out then, drying and get final product.
Embodiment 2: under the normal temperature 0.15 kilogram of salt is dissolved in 5 kg water, no fresh Chinese chestnut infested, that damage was soaked in this salt solution 60 minutes, be encapsulated in the vacuum polybag after pulling out then, drying.
Embodiment 3: under the normal temperature 0.2 kilogram of salt is dissolved in 5 kg water, no fresh Chinese chestnut infested, that damage was soaked in this salt solution 45 minutes, be encapsulated in the vacuum polybag after pulling out then, drying.
