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.

[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...
