Abstract

The invention relates to the field of food detection, in particular to an application of high-content DSM (4-(2-hydroxy isopropyl)-1, 3-cyclohexadiene-1-carboxylic acid-isomaltose) as a linden honey characteristic marker. Meanwhile, the invention provides a basswood honey authenticity evaluation method, and the method comprises the steps: taking DSM as a characteristic compound; when the content of DSM in honey ranges from 250 mg / kg to 450 mg / kg, judging DSM as basswood honey; if not, determining that the honey is other honey or adulterated with linden honey. The method provided by the invention has the advantages of simplicity, high efficiency and the like, is convenient to operate and popularize, has certain guiding significance for formulating related industries or national standards ofhigh-quality linden honey, and also has important practical significance for protecting legitimate rights and interests of honey consumers and maintaining healthy development of the honey consumptionindustry.

Description

technical field [0001] The invention relates to the field of food detection, in particular to the application of high-content DSM as a characteristic marker of linden tree 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. Rapeseed, acacia, jujube, Vitex, linden, milk vetch, lychee, loquat, etc. are the main nectar plants in my country and the main source of bulk honey production in China, and its unifloral nectar is the main form of honey in the market in my country. Tilia bran and Tilia are the main species of linden, and they are mainly distributed in the Changbai Mountains, ...
