Problems solved by technology

[0005] Its chemical properties are relatively stable, and its potency hardly changes after being boiled in water for 5 hours, so it is difficult to remove it by general methods
[0006] At present, there is no effective method to remove chloramphenicol residues in honey. Some people use activated carbon adsorption method or ozone method to remove chloramphenicol in honey, which will cause a large loss of active ingredients such as enzymes in honey. At the same time, the cost is high and the removal effect is poor.

Embodiment 1

[0024] 240 liters of fresh honey in a special iron drum, the content of chloramphenicol in the honey is less than 10 μg / kg, after filling with nitrogen, adopt the method of filling and discharging at the same time, so that the inner space of the container is filled with nitrogen and then seal the container; transport the container into -18 After 4-8 hours of freezing treatment in the cold storage, the frozen honey and containers are irradiated with γ-rays, and the average absorbed dose is 7Kgy; the static stacking is used for irradiation, that is, the sealed containers are stacked, and the irradiation process is based on the irradiation process. When calculating the time to absorb half the dose, change the layer and surface, that is, change the positions of the stacked sealed containers up, down, front and back, so that they can receive a uniform radiation dose. The ratio of the highest accepted measurement to the lowest accepted measurement is about 1.5, and the highest shall ...

Embodiment 2

[0030] 100 liters of fresh royal jelly in a special iron drum, the content of chloramphenicol in the royal jelly is less than 10 μg / kg, after filling with nitrogen, adopt the method of filling and discharging at the same time, so that the inner space of the container is filled with nitrogen and then seal the container; After 4-8 hours of freezing treatment in the 18-degree cold storage, in the frozen state, use γ-ray irradiation, and the average absorbed dose is 10Kgy; use static stacking irradiation, that is, stack the sealed containers, and the irradiation process depends on the irradiation time When calculating the absorbed half-dose, change the layer and the surface, that is, change the positions of the stacked sealed containers up, down, front and back, so that they can receive a uniform radiation dose.

[0031] The content of chloramphenicol in the fresh royal jelly after irradiation treatment and the changes and results of the nutritional components of honey are basicall...

Embodiment 3

[0033] 180 liters of fresh honey in a special iron drum. The chloramphenicol content in the honey is higher than 10 μg / kg. The honey is diluted first. The specific operation method is: add chloramphenicol-free Add plain honey, and stir and mix evenly. The amount of addition is determined according to the initial content of chloramphenicol measured, so that the content of chloramphenicol after mixing is lower than 10 μg / kg.

[0034] The diluted honey is filled with nitrogen, and the inner space of the container is filled with nitrogen, and then the container is sealed. Under normal temperature conditions, the average absorbed dose is 4Kgy. Static stacking is used for irradiation, that is, the sealed containers are stacked on top of each other. During the irradiation process, the layers are changed when the half dose is absorbed according to the irradiation time, and the positions of the stacked sealed containers are changed up, down, front and back, so that they can be irradiate...

Abstract

The invention relates to a radiation degradation method for residual chloromycetin in honey which comprises the following steps, loading bee honey or royal jelly into sealed container, filling nitrogen, sealing the container, subjecting the sealed bee honey or royal jelly to radiation process with gamma beams, the dose range of the radiation degradation additive is 4KGy-10KGy. The method can be applied for degrading the aquamycetin in the bee honey.

Description

technical field [0001] The invention relates to a method for degrading chloramphenicol residues in honey. Background technique [0002] In the beekeeping process, a certain amount of chloramphenicol is usually mixed with honey to feed the bees to prevent and treat diseases of the bees. But long-term use, there is a small amount of residual chloramphenicol in honey, which has serious side effects on the human body. There are strict restrictions on the residual amount of chloramphenicol in honey at home and abroad, and the problem of chloramphenicol residue is also the main factor that plagues the export of bee products in my country. [0003] Chloramphenicol, molecular formula: C 11 h 12 Cl 2 N 2 o 5 [0004] Chemical name: D-threo-(-)-N-[α-(hydroxymethyl)-b-hydroxy-p-nitrophenylethyl]-2,2-dichloroacetamide [0005] Its chemical properties are relatively stable, and its potency hardly changes after being boiled in water for 5 hours, so it is difficult to remove it by ...
