The invention discloses a fast and non-destructive detection method for sugar content of navel orange, which solves the problem that the existing near-infrared spectrum detection technology of navel orange does not consider the interference of the peel on the spectrum and the influence of the size and weight of the fruit, and the detection accuracy is low. The method uses a near-infrared spectrometer to obtain the near-infrared spectrum of navel oranges and navel orange peels, and uses a weight sensor and an ultrasonic sensor to measure the weight, height and diameters in two mutually perpendicular directions of the navel oranges. The influence of the peel on the sugar content detection was eliminated by peeling off one side of the navel orange peel to obtain the spectral attenuation value, and the weight, height and diameter data of the navel orange were used to correct the influence of the size of the navel orange on the sugar content detection of the navel orange. Multiple linear regression was used to correlate the corrected navel orange spectrum with its sugar content, and the linear regression equation of navel orange sugar content was established, so as to realize the rapid and nondestructive detection of navel orange sugar content. The invention can correct and eliminate the influence of navel orange size and pericarp on the sugar content detection of navel orange, and effectively improve the precision of detecting the sugar content of navel orange by using near-infrared spectrum.
Description
technical field [0001] The invention belongs to the field of fruit quality detection, and relates to a method and device for rapid and nondestructive detection of navel orange sugar content. Background technique [0002] Navel oranges are rich in nutrients, with tender and crisp flesh and a sweet taste. They are popular fruits. With the continuous improvement of people's living standards, people not only pay attention to the appearance quality of navel oranges, such as size, color, fruit shape, surface defects, etc., but also pay great attention to the internal quality of navel oranges, such as sugar content and acidity, etc. when purchasing navel oranges. [0003] Near-infrared spectroscopy is a fast, non-destructive and green modern analysis technique. At present, there are some reports on the rapid and non-destructive detection of sugar content of navel oranges and other fruits by near-infrared spectroscopy. A discloses a near-infrared fruit sugar non-destructive detect...
