Abstract

The invention belongs to the technical field of food processing, and discloses a storage and fresh-keeping method for fresh peanuts. The method comprises the steps that fresh peanuts are sterilized; shells of the fresh peanuts are dried to control the water content of the shells of the fresh peanuts less than or equal to 8% and the water loss rate of peanut kernels less than or equal to 5%; the fresh peanuts are placed in an environment with a humidity larger than or equal to 85% and a temperature of 3-8 DEG C for storage. The method has the advantages that no food preservative needs to be adopted for preservative treatment of the fresh peanuts, which not only avoids toxicity hazards of chemical preservatives, but also the human health and environmental protection are facilitated; the color, flavor, taste and nutrient compositions of the peanuts themselves can also be effectively retained, inconvenience and troubles brought by a traditional process are solved, a big problem is solved for traditional delicious boiled peanuts, the needs of broad consumers are met, and the market application prospects are broad.
