Method for identifying rape honey and vervain family honey

Abstract

The invention discloses a method for identifying rape honey and vervain family honey. The method is characterized by comprising the following steps of 1, constructing an identification model by treating provided samples of rape honey and vervain family honey, determining content of amino acids obtained by honey protein hydrolysis, wherein the number of each kind of the samples is greater than or equal to 15, setting Y variables as classified variables, setting values of the Y variables of rape honey and vervain family honey respectively as 0 and 1, setting a threshold value as 0.5, carrying out linear regression of the determined amino acid content and the classified variables of the samples by a partial least square discriminant analysis method, and building the identification model, and 2, carrying out identification by treating honey needing to be identified, determining content of amino acids obtained by honey protein hydrolysis, carrying out identification by the identification model obtained by the step 1 according to the determined amino acid content, and determining if the identified honey belongs to rape honey or vervain family honey. The method can effectively identify rape honey and vervain family honey.

Description

technical field [0001] The invention relates to a method for identifying honey, in particular to a method for identifying rapeseed honey and twig honey. Background technique [0002] As a natural health care product and nutritional product, honey is favored by consumers. However, with the continuous improvement of people's awareness of product quality and safety, manufacturers are required to indicate the source of honey, especially the plant source, that is, the nectar source plant. name. Honey from different nectar plants has obvious differences in taste, smell, color and nutritional components. Due to the trend of interests, some unscrupulous manufacturers will shoddy and confuse real ones. Therefore, it is necessary to develop effective and reliable methods to identify honey plants. source type. [0003] Although there are some differences in the color and smell of honey from different nectar-source plants, it is difficult to distinguish and identify them through these...

Problems solved by technology

This method requires the use of equipment such as Fourier transform near-infrared spectrometers, which has high identification costs and complicated operations. At the same time, the identification results are highly dependent on model establishment.
