Our webinar hosted by Dr. Neal Craft, Chief Scientific Officer of Eurofins, explores the world of natural pigments, testing methods, and unique matrix challenges.


During this webinar, Tim Lombardo of Eurofins Food Assurance discussed the differences between food security, food safety, food fraud, and food defense. He provided a short history of FSMA and reviewed regulations for food defense and intentional adulteration protection.


In response to the rapidly developing, low-calorie sweetener market, Eurofins developed and validated a new HPLC analytical method for allulose determination. Learn more from Eurofins Botanicals, Director of R&D, Dr. Hong You.


This scientific poster demonstrates the importance of appropriate HPLC columns when analyzing Vitamin C in serums.


Steam volatile oil is an important property of spices. The volatile components present in spices contribute to the aroma and flavor of the spice. This paper describes a fast, accurate, and simple technique for analysis of spices using Fourier Transform Near Infrared (FT-NIR) technology.


This study seeks to develop and validate a method for identifying and quantifying four bioactive forms of vitamin B12 (adenosylcobalamin, cyanocobalamin, hydroxocobalamin, and methylcobalamin) from dietary ingredients and supplements, as a consensus quality control protocol for dietary supplement labeling and manufacturing.


Pathogen detection in foods and environmental samples is a critical element in a food management system. This study set out to compare the robustness of Loop Mediated Amplification (LAMP) with that of PCR as illustrated by the detection threshold of Listeria and Salmonella spiked into culture broths previously incubated with various spices.




This poster describes some of the work Eurofins has conducted on procedures to help control the quality of agave syrups.


Originally showcased at the 2016 annual AOAC meeting, this poster presents data for the “new” variety that will be valuable to anyone who buys or uses this type of fruit for processing.
