Detection of camellia oil adulteration based on near-infrared spectroscopy and smartphone combined with deep learning and multimodal fusion.

Food Chemistry
Camellia oil (CO) is known for its nutritional value and health benefits, but its high price makes it susceptible to adulteration. This study developed a binary adulteration system for CO in response to the adulteration of rapeseed oil (RO) into CO that ...

A review of Fourier Transform Infrared (FTIR) spectroscopy used in food adulteration and authenticity investigations

Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2020
The increasing demand for food and the globalisation of the supply chain have resulted in a rise in food fraud, and recent high profile cases, such as the Chinese milk scandal in 2008 and the EU horsemeat scandal in 2013 have emphasised the vulnerability

Adulteration detection of corn oil, rapeseed oil and sunflower oil in camellia oil by in situ diffuse reflectance near-infrared spectroscopy and chemometrics

, 2021
Camellia oil is always found to be adulterated with corn oil, rapeseed oil, and sunflower oil in the market. In this study, a new, real-time, and quantitative detection method for such adulteration was developed based on in situ near-infrared (NIR ...

Adulterers and Adulterators

1992
The ever-increasing death rate among the Portuguese nobility in the wars against Castile,1 civil wars like the Battles of Alfarrobeira (1449) and Toro (1476) and in the Crusade in North Africa, was made even greater by frequent shipwrecks during the maritime explorations and the Portuguese presence in Africa, where these knights built fortresses ...
