Embodiment 1

[0023] Step 1. Record the five attributes of Chinese prickly ash as attribute A, attribute B, attribute C, attribute D and attribute E respectively, including color, fragrance, numbness, particle size and aftertaste; According to the principle of "the higher the importance weight, the higher the score", the pairwise relative evaluation is carried out, and the importance evaluation values ​​of any two attributes are obtained respectively;

[0024] Step 2. Select 3 samples of the same type of Zanthoxylum bungeanum, and record them as S1, S2 and S3 respectively; 15 evaluators use the 5 attributes of Zanthoxylum bungeanum as the standard, and use the 5 attributes of Zanthoxylum bungeanum as the standard to evaluate the three samples according to the principle of "the higher the grade, the higher the score". Principles for pairwise evaluation,

[0025] Obtain the grade evaluation values ​​of 5 attributes of any two samples respectively;

[0026] Step 3. After taking the average of...

Abstract

The invention belongs to the technical field of food measurement, and relates to a method for determining the grade of Chinese prickly ash. The method comprises the following steps: (1) carrying out pairwise relative weight evaluation by an evaluator according to five attributes of a Chinese prickly ash sample; (2) performing pairwise relative grade evaluation on the three Chinese prickly ash samples according to the five attributes of the Chinese prickly ash samples by an evaluator; (3) analyzing the data in the step (1) to obtain weight percentages of the five attributes; (4) analyzing the data in the step (2) to obtain grade evaluation value percentages of the three Chinese prickly ash samples; and (5) combining the results of the steps (3) and (4) to obtain the grades of the three Chinese prickly ash samples. The method overcomes the defects of large volatility and low reproducibility caused by the fact that detection of the Chinese prickly ash grade in the food field depends on subjective evaluation at present.

Description

technical field [0001] The invention relates to the technical field of food measurement, in particular to a method for determining the grade of prickly ash. Background technique [0002] Zanthoxylum bungeanum is an important economic and medicinal plant. Zanthoxylum bungeanum peel is the raw material of essence and spices, the seed is an excellent woody oil plant, the oil cake can be used as fertilizer or feed, and the leaves can be used as seasoning, food or pepper tea instead of fruit; At the same time, Zanthoxylum bungeanum is also an important tree species for soil and water conservation in arid and semi-arid mountainous areas. Traditional Chinese medicine believes that Zanthoxylum bungeanum: main wind evil, warms the middle, eliminates cold numbness, strengthens teeth and hair, and improves eyesight. Main pathogenic cough and adverse, warming, expelling dead muscles of joints and skin, cold-damp arthralgia, lowering Qi. It is precisely because of the importance of pep...
