“…X-rays, which can penetrate matter, are short wave length (0.01 10 nm) radiation that have an energy range of 1.92ϫ10 Ϫ17 to 1.92ϫ 10 Ϫ14 J. X-ray computed tomography could be used to measure internal quality, specially the internal disorder. A 3D model generated from X-ray CT images may be useful for visualizing the internal changes of intact fruit or vegetables during storage (Donis-gonza et al, 2014). Structuredependent physical properties, such as porosity and moisture content, have a direct relationship with thermal properties.…”

The efficacy of 1-MCP in modulating the ethylene sensitivity of Japanese persimmon (Diospyros kaki) in terms of thermal and structural properties was investigated at 0 and 25. X-ray computed tomography was employed to quantify the structural properties. The physicochemical properties were measured destructively and correlated with X-ray image properties. 1-MCP satisfactorily suppressed the ethylene sensitivity in terms of bio-yield stress, L * , and hue angle value at both temperatures. The changes in porosity and thermal conductivity in 1-MCP-treated fruit were smaller than those in control and ethylene-treated fruit. The histogram profile also shifted slightly to a high-density region in 1-MCP-treated fruit. The L * value, hue angle, apparent density, moisture content, bio-yield stress, and TSS were highly correlated with average CT value and standard deviation at both temperatures. Thus, X-ray CT images could be used to quantify the thermal and structural properties, and 1-MCP could suppress the ethylene sensitivity of Japanese persimmon stored at 0 and 25 for 8 and 1 weeks, respectively.

“…The CT number of slice images is an important index to evaluate the internal quality. CT number followed a positive linear relationship with moisture content, acidity, and density, while soluble solids and PH had a negative linear relationship with CT number (Barcelon, Tojo, & Watanabe, ; Donis‐Gonzalez et al., ).

“…Moreover, compared with CT scans, MRI scans typically take much longer to treat. Compare with other NDT technologies, X‐ray CT technology has unique advantages for the above problems. The advantages of X‐ray CT technology include the following (Donis‐Gonzalez et al., ; Kumi, Mao, Hu, & Ullah, ; Wang, ): (a) This technology has a high density and space distinguishable abilities to obtain the high‐quality images clearly and quickly. (b) This technology could measure the X‐ray absorption attenuation of each sample tissue without sample preparation and separation.…”

“…Moreover, these capabilities on voxel could be represented as CT number in a 3D image. The CT number is the attenuation coefficient which is calculated using water, and its unit is Hounsfield (Hu) (Cnudde et al, 2006;Donis-Gonzalez, Guyer, Pease, & Barthel, 2014;Taina, Heck, & Elliot, 2008). The calculation formula of CT number is as follows:…”

The quality of agricultural products relates to the internal structure, which has long been a matter of interest in agricultural scientists. However, inspection methods of the opaque nature of internal information on agricultural products are usually destructive and require sample separation or preparation. X‐ray computed tomography (X‐ray CT) technology is one of the important nondestructive testing (NDT) technologies without sample separation and preparation. In this study, X‐ray CT technology is used to obtain two‐dimensional slice images and three‐dimensional tomographic images of samples. The purpose of the review was to provide an overview of the working principle of X‐ray CT technology, image processing, and analysis. This review aims to focus on the development of the agricultural products (e.g., wheat, maize, rice, apple, beef) and its applications (e.g., internal quality evaluation, microstructure observation, mechanical property measurement, and others) using CT scanner. This paper covers the aspects regarding the advantages and disadvantages of NDT technology, especially the unique advantages and limitations of X‐ray CT technology on the quality inspection of agricultural products. Future prospects of X‐ray CT technology are also put forward to become indispensable to the quality evaluation and product development on agricultural products.

“…As a result, X-ray techniques have been explored to detect several kinds of internal defects in agricultural products. These defects are often detectable with X-ray imaging because they change the tissue density locally or the distribution of the water content (Donis-González et al, 2014;Herremans et al, 2013Herremans et al, , 2014aHerremans et al, , 2014bKotwaliwale et al, 2014;Lammertyn et al, 2003). Bruise damage in apples is one of these defects that has been found to be detectable by using linescanning X-ray equipment (Diener et al, 1970;Schatzki et al, 1997).…”

A non-destructive methodology was developed to automatically detect and quantify bruise volumes in the equatorial region of apples, using X-ray CT images. Grey level threshold values were calculated to segment bruises in 'Jonagold', 'Joly Red' and 'Kanzi' apple fruit using the multi-level Otsu's threshold method. Comparisons were made between the CT-based bruise volume estimates and bruise volume estimates that were based on destructive measurements in combination with simple geometric assumptions. Visualisation of the bruises in both 2 and 3D showed that bruises, resulting from a pendulum impact with a spherical impactor, can be highly irregularly shaped which implies that the bruise volume estimations based on simple geometric assumptions cannot deliver accurate results.
