New paper examines approaches to measuring protein in foods in context of deadly adulterations
Date:8/26/2010

ers vulnerable to potential serious consequences," said Dr. Moore. "Adulteration of foods represents a significant public health threat that needs to be addressed. In this paper, we look at a path forward on the complex issue of protein measurementdevelopment, validation and implementation of new analysis methods specific for protein-based food ingredients."

As described in the paper, protein content is held at a premium because of the nutritional value of proteins as well as their contribution to functional properties of food such as texture and flavor. Thus, protein quantification is an important tool used throughout the global food supply chain, helping to determine the economic value of a food. The authors note that as long as the value of food ingredients is based on protein content, the incentive to adulterate these materials by measures designed to inflate protein measurement will existnecessitating the need for new approaches used by the food industry.

To stimulate discussion and to provide new information about the development and adoption of new or alternative protein methodologies, the authors of the paper review the following:

  • the early history of food protein methodology
  • analytical strategies to prevent intentional adulteration of foods and food ingredients
  • challenges of developing or adopting new or alternative protein quantification methods and associated reference materials
  • criteria against which new methodologies can be evaluated, and
  • emerging methodologies for total food protein measurement, including pros and cons.

The paper looks at the two primary analytical strategies to prevent "economic adulteration of food," which is defined as "fraudulent addition of non-authentic substances or removal or replacement of authentic substances without the purchaser's knowledge for economic gain of the seller." The first approach uses analytical tests to identify one or more suspected adulterants, wh
