Problems solved by technology

So far, scholars at home and abroad have done preliminary research on the use of optical technology to detect pear fruit, but there are few related reports on the establishment of a general model for the soluble solids and titratable acid content of pear fruit for comprehensive analysis

Embodiment 1

[0063] The sample 'Dangshan Suli' was collected at the Meixian Experimental Base of Northwest Agriculture and Forestry University (34°27'N, 107°75'E), Pucheng on September 7, September 10, and September 25, 2021, respectively. Commercial orchards within the Suli Experimental Demonstration Station (34°59'N, 109°59'E), Northwest A&F University Horticultural Field (34°17'N, 108°08'E) to ensure differences between samples , a total of 340 non-damaged pear samples were collected. Pear samples such as figure 2 All the picked pears were transported to the School of Horticulture, Northwest Agriculture and Forestry University, cleaned and numbered randomly, and then placed indoors (20°C and 60% relative humidity) for 24 hours to eliminate the effect of temperature on the test results. Since the information of different positions of the pear fruit is different, three positions with the same spacing were selected on the equatorial plane of each sample to be tested for spectral data col...

Abstract

The invention provides a pear internal quality nondestructive testing model and a construction method thereof, and belongs to the technical field of agricultural product detection. According to the method, pear fruits are taken as an object, a near infrared spectrum technology is utilized, the true values of internal quality indexes of the pear fruits are measured by collecting spectral data of the pear fruits, the internal quality indexes of the pear fruits comprise soluble solid content (SSC) and / or titratable acid (TA) of the pear fruits, and a nondestructive testing model for the internal quality of the pear fruits is established in combination with spectrum pretreatment. According to the method disclosed by the invention, a general model for nondestructive testing of the internal quality of the pear is constructed, and the soluble solid content SSC and / or titratable acid TA of the pear fruit can be measured in a nondestructive, rapid and pollution-free manner in Dangshan pears.

Description

technical field [0001] The invention belongs to the technical field of agricultural product detection, and particularly relates to a construction method for non-destructive detection of internal quality of pears and a method for non-destructive detection of internal quality of pears. Background technique [0002] Pear is an important fruit tree crop. The fruit of pear is not only delicious and juicy, sweet and sour, but also rich in nutrients and contains a variety of vitamins and cellulose. In terms of medical efficacy, pears can clear constipation, facilitate digestion, and are also good for cardiovascular. [0003] Pears are one of the most important consumption and export fruits in my country. With the changes in people's consumption level and consumer demand, people's quality requirements for fresh fruit are becoming more and more demanding. They are no longer limited to the traditional appearance quality such as fruit shape and color. Pay more attention to the internal...
