Micro-damage type pomelo fruit internal quality characteristic detection sampling device and detection method

Abstract

The invention discloses a micro-damage type pomelo fruit internal quality characteristic detection sampling device and a detection method. The micro-damage type pomelo fruit internal quality characteristic detection sampling device comprises a sampling needle, a gas sampler and a filter. According to the invention, when the internal quality characteristic detection of a pomelo fruit is carried out, the sampling needle can penetrate through the peel from the bottom of the pomelo fruit in a micro-damage manner and go deep into the internal center of the pomelo fruit, and the gas sampler is used for carrying out pomelo fruit micro-damage collection on the internal central gas of the pomelo fruit through the gas outlet core, so that gas volatile matters in the internal central gas collection space of the pomelo fruit are directly obtained so as to achieve the micro-damage sampling for detecting the internal quality characteristics of the pomelo fruits; and the micro-damage type pomelo fruit internal quality characteristic detection sampling device is adopted for detection sampling, so that damage-free and accurate pomelo fruit internal quality characteristic detection can be realized.

Description

technical field [0001] The invention relates to the technical field of pomelo internal quality feature detection, in particular to a micro-damage pomelo internal quality feature detection sampling device and detection method. Background technique [0002] Pomelo is a large thick-skinned fruit. The skin has an oil cell layer and a spongy layer, and the pulp is wrapped in a vesicle. It is difficult to accurately and non-destructively detect the internal quality, and it is easy to waste the pulp when performing slice detection. [0003] At present, the non-destructive internal quality inspection of pomelo fruit mainly includes visible / near-infrared reflection spectrum detection, visible / near-infrared transmission spectrum detection, and other non-destructive testing such as machine vision and electronic nose. However, it is not feasible to use visible / near-infrared reflectance spectroscopy to obtain the characteristic information of the pulp due to the thickness of the skin; th...
