Problems solved by technology

Subtropical fruits such as citrus and loquat can tolerate mild cold, but they can still cause severe freezing damage at temperatures around -9°C or below, and are generally only distributed in areas south of the Qinling-Huaihe River

Embodiment

[0067] In the process of use, first, pomelo from Guangdong and Guangxi were selected as samples, and three samples were taken from each production area.

[0068] Next, cut the sample pomelo with a knife into two parts, the peel and the pulp, and number them respectively. 2, 3.

[0069] Again, it is preferable to use grapefruit peel samples for analysis. Weigh 1 g of grapefruit peel and place it directly in a 20ml headspace sampling bottle, tighten the bottle cap, and heat and shake the headspace sampling bottle at 40°C in the incubator according to the instrument setting program After 10 minutes, the sampling needle automatically pipets the gas in the 500ul headspace bottle for analysis, and automatically injects it into the GC-IMS for analysis.

[0070] Thirdly, GC-IMS controls the flow rate of carrier gas and drift gas according to the set program, and obtains the gas phase ion mobility spectrum of the volatile organic compounds in the pomelo peel sample to be tested after ...

Abstract

The invention discloses a detection method for quickly judging fruit producing areas, which adopts a gas phase ion mobility spectrometry (GC-IMS) technology, obtains a gas phase ion mobility spectrogram by detecting the variety and content of volatile organic compounds in fruits, and obtains a fingerprint spectrum and principal component analysis (PCA) of the volatile organic compounds in the fruits after analysis. According to the obtained fingerprint spectrum and principal component analysis (PCA), the fruit producing area can be judged, a traditional smell smelling method is digitized, andscientific research workers and producers or merchants are assisted in identifying the fruit producing area or the specific producing area.

Description

technical field [0001] The invention relates to a detection method for quickly judging the origin of fruits. Background technique [0002] my country has a vast territory and a wide variety of fruits, and the geographical distribution of fruits is also concentrated according to the types of fruits and the climatic conditions they need. In my country, tropical and subtropical fruits such as coconut, mango, pineapple, longan, lychee, grapefruit, banana etc. are most afraid of the low temperature of 0 ℃, so they are only distributed in southern China. Subtropical fruits such as citrus and loquat can tolerate mild cold, but they can still cause severe freezing damage at low temperatures of around -9°C or below, and are generally only distributed in the areas south of the Qinling-Huaihe River. The temperate zone north of Qinling-Huaihe River is rich in temperate fruits such as apples, pears, persimmons and grapes. In the north of the Great Wall of my country and northern Xinjian...
