Rapid detection and quantification of the adulteration of orange juice with grapefruit juice using handheld Raman spectroscopy and multivariate analysis

Abstract

Detecting food adulteration has always been an important task for food safety. Especially when grapefruit is the adulterant as components in the juice have undesired interactions with many medicines. In...

Advance in application of rapid non-destructive testing technology in the detection of apple mold heart disease

“…Through molecular vibration and rotation, structure and other relevant information are obtained for detection [16] . A variety of fruits and vegetables use Raman spectrum combined with different models to judge their internal quality through the detection of maturity, organic content, component ratio and other data, so as to achieve the purpose of internal quality detection [20][21] However, Raman spectroscopy has great potential in the field of detection of apple mold heart disease. Josu et al used Raman spectroscopy technology and confocal Raman microscopy with 514 nm excitation laser wavelength to extract the main information of organic components in the sample, as shown in Figure 2 [22] .…”

Feasibility of an NIR spectral calibration transfer algorithm based on optimized feature variables to predict tobacco samples in different states

“…NIR spectroscopy is extensively used in the detection and quality control of complex natural products, such as agricultural products, 7,8 Chinese herbal medicines 9,10 and petroleum, 11,12 due to its recognized advantages of being rapid, efficient, non-destructive and green. 13 Moreover, in the tobacco industry, [14][15][16] it has been used successfully for a long time.…”

Rapid quantification of goat milk adulteration with cow milk using Raman spectroscopy and chemometrics

“…15–19 What is more, it also has great potential in the detection of other types of food, for instance, honey, clove essential oil, butter; orange juice, and fresh coconut water. 20–24…”

“…[15][16][17][18][19] What is more, it also has great potential in the detection of other types of food, for instance, honey, clove essential oil, butter; orange juice, and fresh coconut water. [20][21][22][23][24] All of these indicate that Raman spectroscopy has great potential and the possibility in the identication and quantitative detection of cow milk adulterated in goat milk. It was reported that goat milk adulterated with cow milk was analyzed based on b-carotene in cow milk by Raman spectroscopy combined with chemometric techniques.…”
