Color developing agent for fast detecting high-whiteness flour wheat seed resource and use method

Abstract

The invention discloses a color developing agent for fast detecting the high-whiteness flour wheat seed resource and a use method, and belongs to the technical field of wheat flour whiteness detection. On the basis of using a phenol reagent, the phenol solution concentration is regulated; copper sulfate pentahydrate in certain concentration is added; two kinds of solutions in different concentration are mixed into the color developing agent to soak seeds; through seed coat staining reaction, the high-whiteness flour wheat seed resource is identified. Large-scale instruments with complicated tasks are not needed; meanwhile, the flour whiteness detection is moved to the field from a laboratory; by the method, the seeds can be collected at any time in any place in the field; then, the seeds are put into a small beaker for directly performing staining reaction to detect the high-whiteness flour wheat seed resource.

Description

technical field [0001] The invention belongs to the technical field of high-whiteness flour wheat seed detection, in particular to a color developing agent for rapid detection of high-whiteness flour wheat germplasm resources Background technique [0002] Whiteness is one of the main sensory indicators of flour quality. Residents and consumers in my country have higher requirements for flour whiteness. The whiteness of flour on the market requires more than 80. During the breeding process of high whiteness wheat varieties, most of them are selected for high whiteness. Germplasm resources, that is, the flour whiteness is above 80. At present, the commonly used methods for measuring the whiteness of wheat flour are whiteness meter measurement, near-infrared reflectometer, and visible near-infrared reflectometer. There are also 1.0% phenol soaked wheat seeds for 15 minutes, and then take them out and place them on the pavement with a mass concentration of 1.0%. In a petri dish ...

Problems solved by technology

[0003] Although the existing methods for detecting flour whiteness can detect flour whiteness, there are many shortcomings. The disadvantages of whiteness meter for measuring flour whiteness are: sample preparation is complicated, the test cost is high, the time is long, and the required instruments are relatively complex. Many, and these instruments are expensive, and a large amount of seeds is required to detect the whiteness at the same time

At the same time, in order to improve the applicability of the model, the model is constantly maintained and updated, which consumes a lot of manpower, energy, and financial resources; the method of using phenol reagents with a drying oven to indirectly identify the whiteness of flour is cumbersome and takes a long time. expensive drying oven
