Embodiment

[0017] A method for cold storage of thin-shell hickory nuts in modified atmosphere packaging, characterized in that first segmental drying, then static irradiation, and finally refrigeration in modified atmosphere packaging:

[0018] Segmented drying: After the thin-shelled pecans are harvested, select pecans without damage and pests, spread them in a single or double layer in an oven, first bake at 30-40°C for 5 hours, and then dry them at 50°C Bake at -60°C for 20 hours, and finally at 25-35°C for 25 hours, and turn it up and down every 1 hour during the drying process;

[0019] Static irradiation process: the hickory nut after above-mentioned drying is used the radiation source of 0.4kGy 60 Coy is processed, and each dose can process 50kg pecans;

[0020] Modified atmosphere packaging and cold storage: pre-cool the above-mentioned irradiated hickory nuts in a cold storage at 4-6°C for 20 hours, put them into a 50 μm white polyethylene bag, heat-seal the seal, and carry out...

Abstract

The present invention discloses a cold storage method of modified atmosphere packaged carya illinoinensis kernels. The method is characterized by comprising the following steps of carya illinoinensis collecting and picking, sectional drying technology using in an oven, then static irradiation technology conducting, and then modified atmosphere packaging and cold storing. A processing technology of cream flavored carya illinoinensis kernels comprises the following steps of firstly shelling and washing, then pre-cooking to be tasty, then drying and dehydrating, stir-frying, cooling and sterilizing, and N<2> filled modified atmosphere packaging.

Description

technical field [0001] The invention relates to the field of pecans with thin shells, in particular to a refrigeration method for pecans with modified atmosphere packaging. Background technique [0002] Thin-shelled hickory is a plant of the genus Hickory in the family Juglandaceae. It is an ecological and economical tree species integrating high-grade thousand fruits, high-grade woody oil, high-quality hard broadwood and landscaping, and has certain economic, social and ecological benefits. Benefits, broad prospects for development, has developed rapidly in recent years. Walnut kernels are high in fat and protein, contain a large amount of unsaturated fatty acids, and contain a variety of amino acids, which have good nutritional value. However, because of its high fat content, its quality is often reduced due to oil rancidity and oxidation, so it is necessary to study how to dry or freshly store walnuts. Contents of the invention [0003] The technical problem mainly so...
