Embodiment 1

[0013] The acacia honey that has been placed for half a year is directly placed on the irradiation shelf and irradiated with gamma rays. After irradiation at a dose of 5KGy, the content of 5-hydroxymethylfurfural in the honey drops from 50.2mg / kg before irradiation to 3.4mg / kg, the degradation rate is 93.2%.

Embodiment 2

[0015] Vitex honey that has been placed for one year is directly placed on the irradiation shelf and irradiated with gamma rays. After irradiation at a dose of 10KGy, the content of 5-hydroxymethylfurfural in the honey decreases from 72.1mg / kg before irradiation To 3.5mg / kg, the degradation rate is 95.1%.

Embodiment 3

[0017] Litchi honey that has been placed for half a year is directly placed on the irradiation shelf and irradiated with gamma rays. After irradiation at a dose of 15KGy, the content of 5-hydroxymethylfurfural in the honey drops from 42.1mg / kg before irradiation to ND, the degradation rate was 100%.

Abstract

The invention relates to a 5 - hydroxymethyl-furfural irradiation degradation method in honey, wherein the 5 - hydroxymethyl-furfural is subjected to irradiation degradation by using Gamma-ray and the irradiation dose is 5KGy-15KGy. The method not only degrades the HMF content in honey to below 10mg / kg and the degradation rate of the 5 - hydroxymethyl-furfural is more than 90%, but also contents of various sugars and the various enzymatic activities are basically kept and the inherent appearance color and flavor are kept. In addition, the operation method is simple and the cost is low and application is wide.

Description

technical field [0001] The invention relates to a method for irradiating and degrading 5-hydroxymethylfurfural in honey. Background technique [0002] Honey has high nutritional value and is favored by consumers. However, consumers should also consider its freshness when purchasing honey, and should not buy it blindly. Fresh and pure honey does not contain hydroxymethylfurfural, but as the storage time prolongs, the six-carbon sugars in honey, mainly glucose and fructose, will be partially dehydrated to form hydroxymethylfurfural under acidic conditions. Honey processing and storage temperature can accelerate the rate of hydroxymethylfurfural formation. Eating honey with a high content of hydroxymethylfurfural will have adverse effects on the human body. [0003] 5-Hydroxymethylfurfural (HMF), molecular formula: C 6 h 6 o 3 , its chemical properties are relatively stable, and it is difficult to remove it by general methods. At present, there is no effective method to r...
