Example Embodiment

[0038] Example 1

[0039] A method for quickly identifying the quality and origin of Yunnan ham. The method includes the following steps:

[0040] Step S1, the establishment of the volatile organic compound database of Yunnan ham from different origins:

[0041] After washing and trimming Yunnan hams from different origins, the ham biceps femoris was removed to remove fat and connective tissue. After being chopped with a chopper, it was detected by a flavor analyzer to obtain gas-phase ions of Yunnan ham samples from different origins. Migration spectrum and fingerprint spectrum;

[0042] Specifically: take Xuanwei ham, Sanchuan ham, Nuodeng ham, Saba ham and Heqing ham respectively. After washing and trimming, take the ham biceps, remove the fat and connective tissue, and chop it with a chopper. Take 1g of ham samples from each place and place them in a 20mL headspace sample bottle. The detection conditions of the flavor analyzer are shown in Table 1, and the system conditions are ...

Abstract

The invention relates to a method for rapidly identifying the production place of ham. The method comprises the following steps that: volatile components of hams from different producing areas are detected by adopting a gas phase-ion mobility spectrometry; characteristic information of a ham sample by using ion drift time and ion strength corresponding to the compound at different retention timesis characterized, response strength data of a ham standard sample is compared and analyzed by adopting a statistical analysis method to establish a database of volatile organic compounds of hams fromdifferent producing areas; and the volatile compounds of a to-be-detected ham by adopting a gas phase-ion mobility spectrometry with the same parameters are detected, and the volatile compounds of theto-be-detected ham are compared with the established database to determine the production place of the to-be-detected ham. The method can be used for objectively, quickly and accurately analyzing thedifference of flavors of the hams from different producing areas, makes up for the subjective defect in the conventional sensory analysis, fills up the blank that the requirements on evaluation effect and efficiency cannot be met in the conventional detection technology, and can be applied to identification of the producing areas of the hams.

Description

technical field [0001] The invention belongs to the field of rapid analysis and detection, and relates to a method for quickly identifying the origin of ham based on a gas phase-ion mobility spectrometry (GC-IMS) technology combined with a chemical analysis method. Background technique [0002] Ham is a cured meat product processed by traditional techniques. It is deeply loved by consumers because of its unique flavor and taste. There are many kinds of ham, and the flavor of ham is closely related to the place of origin, processing technology and fermentation time, etc. These differences can lead to the difference of volatile compounds in ham. Generally speaking, ham should not be less than 10 months from curing to maturity, and the older it is, the more fragrant it will be, and the higher its value will be. In order to pursue high profits, unscrupulous merchants pass off cold storage hams as well-known brand hams. In addition, hams from different origins will have differe...
