In-depth chemometric strategy to detect up to four adulterants in cashew nuts by IR spectroscopic techniques

NIR Sensing Technologies for the Detection of Fraud in Nuts and Nut Products: A Review

“…Finally, regarding the detection of adulterants in the commercialized product, a wide range of adulterants can be found in the studies reviewed, such as was suggested by the presence of green peas in pistachio nut products, given the lower price of the former [ 45 , 46 ]; the presence of bitter almonds in batches of sweet almonds, which can affect consumer safety [ 47 , 48 ]; the adulteration of cashew nuts with other allergenic nuts [ 49 , 50 ]; and the detection of foreign bodies in Chinese hickory nuts, such as shell fragments that can be harmful for human consumption [ 51 ]. To address these issues, different chemometric approaches were tested in the reviewed documents by means of the development of quantitative and qualitative models to detect fraud in nuts.…”
