Embodiment 1

[0058] 1. Sample source

[0059] A total of 80 common real organic honey samples purchased from the market or beekeepers were used to detect the content of 4-hydroxyquinoline in various honeys, including jujube flower, rapeseed, acacia, litchi, longan, vitex, linden, Snow lotus, sunflower, tallow, pomegranate, wild osmanthus, wild bazi, caragana, manuka, old melon head, wolfberry, codonopsis, eucalyptus honey 4 samples each (4 samples of each honey come from different origins , with differences in the degree of processing), and 2 samples of gallnut and citrus honey (the 2 samples of each honey come from different origins, and the degree of processing is different).

[0060] 2. Solution preparation

[0061] Extraction solution: pipette 20 mL of methanol, and dilute to 100 mL with ultrapure water. Store at 4°C.

[0062] 4-Hydroxyquinoline standard solution: Weigh 10 mg of 4-Hydroxyquinoline standard, and dilute to 10 mL with methanol. Store at 4 ℃, valid for 2 months.

Abstract

The invention relates to the field of food detection, and in particular to application of high-content 4-hydroxyquinoline as characteristic marker of jujube honey. The invention also provides a tracing identification method for detecting the jujube honey. When the content of 4-hydroxyquinoline, as a characteristic compound, in honey is between 3.5 and 5.5 mg / kg, the honey is determined to be jujube honey; and otherwise, the honey is determined to be other honey or adulterated jujube honey. The provided method is simple and efficient, convenient to popularize and operate, and has great significance in protecting legitimate rights and interests of honey consumers and maintaining healthy development of honey consumption industry.

Description

technical field [0001] The invention relates to the field of food detection, in particular to the application of high-content 4-hydroxyquinoline as a characteristic marker of jujube flower honey. Background technique [0002] Honey is a natural sweet substance that is fully brewed by bees from the nectar, secretion or honeydew of plants collected by bees, combined with their own secretions. Due to the rich nutritional value of honey, it is favored by consumers, and its sales volume is also on the rise year by year. my country has a vast territory, complex terrain, diverse climates, rich resources, and rich and colorful nectar plants. my country's main honey sources are: rapeseed, acacia, jujube, Vitex, linden, milk vetch, litchi, loquat and so on. Among them, jujube flower honey source plants are cultivated in most provinces and cities in the country, especially in the North China Plain. In 2018, the jujube flower planting area nationwide reached 3.25 million hectares, am...
