Problems solved by technology

Existing literature research shows that the content of mineral elements can be used as a traceability index to characterize the origin information of plant-derived agricultural products, but the content of mineral elements in agricultural products is affected by the climate conditions of the year, variety differences, irrigation and fertilization factors, and the absorption and metabolism of mineral elements in plants, etc. factors, thus affecting the accuracy of origin traceability

Embodiment 1

[0035] Example 1: A Traceability System for the Origin of Turpan Raisins

[0036] The present invention specifically provides a traceability system for the origin of raisins in Turpan, which is established through the following method steps:

[0037] (1) Collect raisin samples from different origins, remove impurities such as stems and peduncles, and wash them with high-purity water;

[0038] (2) Put the raisin sample obtained in step (1) into an oven at 60° C. for 1 hour to be air-dried until the moisture content is lower than 7%. After mixing the sample with high-purity water at 1:1, grind it evenly with a knife mill;

[0039] (3) Accurately weigh 2 g of the raisin sample ground in step (2), put it in the microwave digestion inner tank, add 5 mL of nitric acid, put the lid on for 1 hour, tighten the tank lid, and carry out microwave digestion;

[0040] (4) Take out the inner tank of the digestion tank cooled in step (3), open the lid and exhaust it, put it on a temperature-...

Embodiment 2

[0043] Embodiment two: Determination of content of mineral elements in raisins

[0044] Remove impurities such as stalks and peduncles from the raisin samples, wash them with high-purity water, and put them into a 60°C oven for 1 hour to blow dry until the moisture content is lower than 7% (the moisture content of the original raisins from the three origins is all lower than 7%). After the sample was mixed with high-purity water at 1:1, it was ground evenly with a knife mill.

[0045] Accurately weigh 2 g (accurate to 0.001) of the ground raisin sample into the microwave digestion inner tank, add 5 mL of nitric acid, cover it and leave it for 1 h, tighten the tank cover, and carry out microwave digestion according to the standard operating procedures of the microwave digestion instrument. After the digestion program is completed, cool down and take out the inner tank, slowly open the tank cover to exhaust, rinse the inner cover with a small amount of water, place the digestion...

Embodiment 3

[0054] Embodiment 3: Utilize 29 kinds of mineral element contents to carry out discriminant analysis of raisin production area

[0055] According to the determination results of raisin mineral elements provided in the above-mentioned Example 2, using 29 kinds of mineral elements whose content is higher than the detection limit of the method, the origin of the raisin samples sampled in the three production areas of Turpan, Hotan and Samarkand is discriminated, and the Fisher function is used , cross-validation for discriminant analysis, the results are shown in Table 2.

[0056] Table 2: Discrimination results of mineral elements in raisins from 3 production areas

[0057]

[0058]

[0059] Notes: a. 100.0% of the original grouped cases were correctly classified. b. Cross-validate only for the cases in the analysis. In cross-validation, each case is classified by those functions derived from all cases except that case. c. Correctly classifies 94.4% of the grouped cases...

Abstract

The invention discloses a method for tracing the origin of Turpan raisins based on various mineral elements. First, raisin samples from different origins were collected, and after pre-treatments such as destemming, stalking, drying, and grinding, the samples were analyzed by inductively coupled plasma mass spectrometry and inductively coupled plasma emission spectrometry for 50 mineral elements; combined with principal component analysis and Discriminant analysis was carried out with Fisher function and cross-test, and the origin of the raisins in the three production areas of Turpan, Hotan and Samarkand of Uzbekistan was traced, and the origin traceability model was constructed; then the mineral element analysis was carried out on the samples to be tested and based on the origin traceability model Analyze and identify the origin of the samples to be tested. The method is broad-spectrum, fast, and accurate, with an accuracy rate of up to 100%. It can effectively identify the traceability of the sample's origin, which is of great significance and has a great application prospect for quality control and risk traceability of the Turpan raisin market.

Description

[0001] field of invention [0002] The invention relates to the technical field of traceability of raisins. Specifically, the present invention relates to the technical field of establishment and application of a Turpan raisin origin traceability system. Background technique [0003] The geographical indication product Turpan raisin tastes sweet, the meat is delicate, the sugar content is as high as 75%, and its nutritional value far exceeds that of raisins produced and processed in other domestic production areas and abroad. The raisins made from Turpan seedless white grapes are known as "Chinese Green Pearls" by the international market. In 2017 / 2018, China's raisin production was about 190,000 tons, and Turpan raisins accounted for more than 80% of the total output. During the same period, my country's raisin imports were about 38,000 tons, and Uzbekistan's imports of raisins accounted for about 66% of the total imports. In recent years, with the active raisin market in m...
