GC team work on isotope ratio analysis of coffee beans
바카라 사이트 Chemist scientists publish research work on the analysis of isotopic composition of coffee beans as a marker of regional origin to combat food fraud
Consumers need to have access to food that is safe, nutritious and is what the label says it is. Food fraud, including economically motivated adulteration, presents a challenge to ensuring food authenticity. This is particularly an issue with foods of high economic value such as coffee, one of the most commercialised and widely consumed beverages in the world.
Isotope ratio analysis is a valuable tool that can be used for food authenticity testing. 바카라 사이트 Chemist scientists at the聽聽at LGC have published their research work in collaboration with the聽, on the effect of roasting on the聽boron isotopic composition of coffee beans.
Boron (11) isotope values of green and roasted coffee beans from 20 locations worldwide were studied with the aim to investigate聽聽fractionation during roasting.
The study showed that boron isotopic composition of roasted coffee聽can聽be used as a marker of regional differences in coffee origin.
