Abstract

The invention provides a prepared reagent for quickly detecting saccharose in honey and a storage method and a detection method of the prepared reagent. The prepared reagent is prepared from the following raw materials in parts by weight: 75-83 parts of a filler, 0.5-1.5 parts of a color developing agent, 15-20 parts of phosphate, 0.5-1.2 parts of sucrose isomerase, 0.6-1.2 parts of glucosyl oligosaccharide oxidase and 0.5-1.2 parts of horse radish peroxidase. The prepared reagent is convenient to carry, simple and efficient in operation process, high in security and strong in anti-jamming capability, large-scale instrument equipment is not needed, and detection results are visual and visible; the detection sensitivity is high, and by use of a spectrophotometer, the limit of detection canreach 1.0 mg / L; and the detection method is high in recovery rate and excellent in reproducibility.

Description

technical field [0001] The invention relates to the technical field of rapid detection of food safety, in particular to a prefabricated reagent for rapid detection of sucrose in honey with high sensitivity and simple operation, and its storage and detection methods. Background technique [0002] Bees collect nectar, secretions or honeydew from plants, mix them with their own secretions, and then fully brew natural sweet substances. Honey contains a variety of inorganic salts and vitamins, iron, calcium, copper, manganese, potassium, phosphorus and other organic acids and trace elements that are beneficial to human health. It also contains sugars and a variety of amino acids. High health effects and nutritional value, deeply favored by consumers. In recent years, the demand for honey in the domestic and international markets has continued to expand. However, the output of honey is difficult to meet the demand of the market, and due to the different sources of honey, there ar...
