Evaluation and tracing method for nutrition quality information of leafy vegetables

Abstract

The invention discloses an evaluation and tracing method for the nutrition quality information of leafy vegetables. The evaluation and tracing method comprises the following steps: setting evaluation indexes for evaluating the quality of the vegetable to be measured; measuring measurement values of all the evaluating indexes; calculating subordinative function values of all the evaluating indexes; calculating an average subordinative function value of good-quality indexes and an average subordinative function value of bad-quality indexes; calculating the difference value between the average subordinative function value of the good-quality indexes and the average subordinative function value of the bad-quality indexes as reference values and the difference value between the average subordinative function value of the good-quality indexes and the average subordinative function value of the bad-quality indexes as measured values; carrying out quality evaluation on the quality of the vegetable to be measured; carrying out coding design based on a two-dimension code to the result of the quality evaluation. The evaluation and tracing method disclosed by the invention has the beneficial effects that comprehensive evaluation for the nutrition quality of the vegetables is carried out, and a nutrition index content and an evaluation result are also added into a tracing system as the nutrition quality information of a product, and then consumers can conveniently obtain the needed nutrition quality information of the vegetables by the two-dimension code.

At present, there is no scientific and comprehensive evaluation of the quality of vegetables in the market. The existing quality evaluations are generally based on a certain element or a nutritional value of vegetables, and this evaluation is based on a type of vegetable. The evaluation conducted did not take into account the fact that the nutritional value of different vegetables in different regions and batches is not the same. In addition, the existing evaluations are all used as a reference for the nutritional standards of certain types of vegetables, which cannot be used in real life. Get the actual nutritional value of a certain vegetable, as well as the nutritional value of vegetables in a certain market at the same time or in different periods
