Embodiment 2

[0048] Embodiment 2, the Chinese prickly ash powder quality detection method based on component analysis

[0049] The present embodiment takes the Zanthoxylum bungeanum sample that numbering is HD11008 as detection object, carries out the test to the Zanthoxylum bungeanum sample of 10 batches with the operation method of the embodiment of the present invention 1, each sample is measured in parallel twice, respectively to the aroma in Zanthoxylum bungeanum powder. camphor, linalyl acetate, β-caryophyllene and meth-caryophyllene were quantified, and the content range was ±10% of the test result (average value). The results are shown in Table 1 below.

[0050] Table 1 Contents of linalool, linalyl acetate, caryophyllene and caryophyllene in Zanthoxylum bungeanum powder

[0051]

[0052] It can be seen from the above table 1 that through the controllable sample pretreatment steps, the obtained Zanthoxylum bungeanum extract was quantitatively analyzed by gas chromatography-mas...

Abstract

The invention discloses a method for detecting the quality of pepper powder based on component analysis. A certain amount of the pepper powder is distilled through water vapor to prepare a pepper extract solution, the obtained pepper extract solution is subjected to component analysis through a gas chromatographic mass spectrometry method, characteristic chemical components including linalool, linalyl acetate, beta-caryophyllene and alpha-caryophyllene in the pepper extract solution are selected as main target components, phenylethyl propionate is selected as an internal standard substance, and linalool, linalyl acetate, beta-caryophyllene and alpha-caryophyllene in the pepper extract solution are quantitatively analyzed with a selected ion gas chromatographic mass spectrometry method to determine the content and range of linalool, linalyl acetate, beta-caryophyllene and alpha-caryophyllene. The method for detecting the quality of the pepper powder based on the component analysis is capable of quickly, simply, flexibly and accurately detecting the quality of the pepper powder and can be widely applied.

Description

technical field [0001] The invention belongs to the technical field of condiment quality detection, and relates to a method for detecting the quality of pepper powder based on component analysis, specifically referring to the detection of linalool, linalyl acetate, and acetylene in pepper powder by gas chromatography-mass spectrometry. Method for quality determination of caryophyllene and caryophyllene content. Background technique [0002] In recent years, in the field of food safety in my country, various incidents of adulterated and counterfeit food have occurred frequently. People's material living standards are improving day by day, but the color and fragrance of the delicacies on the table are greatly reduced, the prickly ash is not numb, the chili is not spicy, and the sesame oil is not fragrant. Adulteration of seasoning powder as a raw material for food production is not uncommon. The general method of counterfeiting is to mix other substances with lower prices in ...
