Problems solved by technology

At present, there are mainly three types of storage methods for Jerusalem artichoke tubers: one is the overwintering storage in the soil of the origin, that is, the tubers are not harvested immediately after they mature, but are harvested according to production and needs, but there are certain requirements for the local climate and temperature. If it is lower than -5°C, it will prevent tuber frostbite, and at the same time affect the continuity of the supply of raw materials for production and processing of enterprises; the second is to store the tubers at low temperature (about 4°C) after harvesting, which can prolong the fresh-keeping storage period of Jerusalem artichoke tubers. The disadvantage is the cost input At the same time, the tubers of Jerusalem artichoke are easy to rot if they are piled up together; the third is to harvest the tubers before freezing in autumn in areas with low winter temperatures, and then store them in cellars. This method takes up a lot of space and the rot of Jerusalem artichoke is serious

Embodiment 1

[0023] Step 1: Soak the perlite in water for 30 minutes, remove it, and mix it with sawdust at a volume ratio of 2:8 to make a matrix, and set aside;

[0024] Step 2: Choose a packing box with a length of 54cm×width 54cm×height 20cm, first spread a layer of 2cm thick substrate on the bottom of the packaging box, then spread a layer of Jerusalem artichoke on the substrate, and spread a layer of 2cm thick wood chips on the Jerusalem artichoke to ensure The sawdust just completely covers the Jerusalem artichoke, and a layer of Jerusalem artichoke and a layer of sawdust are repeated until the packing box is filled and sealed;

[0025] Step 3: Put the sealed packing box into the hanging column of the assembly line, and use Co 60 The gamma rays are irradiated at a dose rate of 1000Gy / h;

[0026] Step 4: After the irradiation treatment, take out the packaging box, open the seal, cover the Jerusalem artichoke with a layer of 3cm thick sawdust, then seal it, and store it at room tempe...

[0030] Step 3: Put the sealed packing box into the hanging column of the assembly line, and use Co 60 The gamma rays are irradiated at a dose rate of 2000Gy / h;

[0031] Step 4: After the irradiation treatment, take out the packaging box, open the seal, cover the Jerusalem artichoke with a layer of 2cm thick sawdust, then seal it, and store it at room temp...

Embodiment 3

[0033] Step 1: Soak the perlite in water for 20 minutes, take it out, then mix it with sawdust at a volume ratio of 3:7 to make a matrix, and set aside;

[0034] Step 2: Choose a packing box with a length of 54cm×width 54cm×height 20cm, first spread a layer of 3cm thick substrate on the bottom of the packaging box, then spread a layer of Jerusalem artichoke on the substrate, and spread a layer of 3cm thick wood chips on the Jerusalem artichoke to ensure The sawdust just completely covers the Jerusalem artichoke, and a layer of Jerusalem artichoke and a layer of sawdust are repeated until the packing box is filled and sealed;

[0035] Step 3: Put the sealed packing box into the hanging column of the assembly line, and use Co 60 The gamma rays are irradiated at a dose rate of 3000Gy / h;

[0036] Step 4: After the irradiation treatment, take out the packaging box, open the seal, cover the Jerusalem artichoke with a layer of 1cm thick sawdust, then seal it, and store it at room te...

Abstract

The invention discloses a jerusalem artichoke tuber normal-temperature storage method. Jerusalem artichoke is processed through Co60 gamma-ray irradiation, a perlite and wood bit mixed substrate is used for light avoiding moisturizing storage, and germination and rotting of jerusalem artichoke can be effectively restrained. Meanwhile, the jerusalem artichoke is covered with 1-3 cm thick wood bitsfor performing light avoiding, acid regulating and color protecting, the jerusalem artichoke is white and bright in color, the fruits are fresh, and the commodity is good. The method is easy to implement and low in cost, and the storage time can be 120-150 d.

Description

technical field [0001] The invention belongs to the technical field of rhizome plant storage, and relates to a method for storing Jerusalem artichoke tubers at normal temperature. Background technique [0002] Jerusalem artichoke (Helianthus tuberosus), commonly known as Jerusalem artichoke, devil ginger, is a perennial herbaceous plant. Native to North America, it was introduced to Europe in the 17th century and then to China. It blooms in autumn and has small yellow flowers shaped like chrysanthemums. Its underground tubers are rich in starch, inulin and other fructose polymers. It can be eaten, cooked or porridge, pickled pickles, dried artichoke in the sun, and made Starch and alcohol are used as raw materials, and its tubers or stems and leaves are used as medicine, which has the effects of diuresis and dehumidification, clearing heat and cooling blood, benefiting the stomach and harmonizing the middle. [0003] The post-harvest rot of Jerusalem artichoke tubers serio...
