Example Embodiment

[0029] Example 1

[0030] (1) Selection of storage materials

[0031] Select the mature, undamaged, and intact truffles produced from December to January-February of the next year for sorting. The sorting standard is based on the size and diameter of the truffles. , This case selects C grade 5-10cm.

[0032] (2) Removal of impurities: Use disinfected tap water and a brush to remove the soil on the surface of the truffles, and then individually wrap each truffle with a bubble bag for later use.

[0033] (3) Low temperature treatment: After the truffles are sorted and removed from the bubble bag, they are treated under cold air at 0-4°C for 10 hours. The surface of the truffles must be fully exposed to the cold air, and the heat and surface moisture of the truffles will be quickly carried away. Go and achieve a rapid cooling, so that the truffle temperature drops to 2°C.

[0034] (4) Ozone disinfection: place the truffles treated at low temperature in a confined space, and use an ozone ...

Abstract

The invention relates to the technical field of fresh keeping and storage of wild mushrooms, and in particular to a fresh keeping and storage method of truffles. The flavor and the taste of the truffles still can be kept under the situation that no chemical reagents are added in a storage process. The fresh keeping and storage method comprises the following steps: (1) truffles pretreatment; (2) low-temperature treatment; (3) ozone disinfection; (4) packaging and storage. By adopting the fresh keeping and storage method disclosed by the invention, the fresh keeping and storage time of the truffles is greatly prolonged, effective component structure and unique fragrance of kames are reserved, worm damage and lesion are not found during a preservation period, and better appearance, unique fragrance and unique sensory quality of the truffles are maintained; the fresh keeping problem during long-time storage and long-distance transportation processes of the truffles is met.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping and storage of wild mushrooms, in particular to a method for fresh-keeping and storage of truffles. Background technique [0002] Truffles (truffles) aliases: pig arch bacteria, grainless vine fruit, mountain skid, belong to Eumycota (Eumycota), Ascomycotina (Ascomycotina), Truffles (Tuberales), Truffles (Tuberaceae), Truffle Fungus (Tuber), external shape: Ascocarp is irregular spherical, oval, dark brown, dark brown, yellowish brown when fresh. It is a rare edible and medicinal fungus that grows in the shallow surface soil layer of coniferous and broad-leaved mixed forests such as Huashan pine, Chinese fir, oak oak, and mulberry. Truffle is a rare and rare edible fungus, which has high nutritional value, medicinal value and economic value, and is one of the favorite fungi in Europe and America. However, because there are many problems in the present fresh-keeping technology, such expensi...
