SCIENTIFIC SESSIONS – WEDNESDAY

1:00 pm – 2:30 pm

Analyses of Carbohydrates and Dietary Fiber

Carbohydrates are widely used in food and supplemental

nutrition products as a major energy source, sweeteners,

and for improving texture. Carbohydrates, such as dietary

fibers, can also provide functional benefits. Unlike other

nutrients, dietary fiber derives its nutritional value not from

being digested and absorbed but remaining undigested

while passing through the stomach and small intestine

and being partially or fully fermented in the large intestine.

With increasing consumer awareness and progressing

regulations, specific and accurate analyses of carbo-

hydrates, including simple sugars, complex digestible

carbohydrates, and dietary fibers, are of great importance.

While liquid chromatographic methods are widely used to

quantify specific sugars and oligosaccharides, quantitative

measurement of dietary fibers depends on measuring

resistance to digestion. Key to dietary fiber methodology is

accurately simulating the human digestion system, method

reproducibility, and assuring capture and quantitation of the

digestion resistant fraction of the food.

This scientific session will provide an update on the use and

analysis of carbohydrates and dietary fibers in food prod-

ucts, as well as other technical considerations.

Analytical Roundtable for Regulators and the

Regulated: Analytical Laboratories and the

Dietary Supplements cGMP Challenge

Current Good Manufacturing Practice regulations for

Dietary Supplements have now been in place since 2007,

and full compliance has been required since 2010. Several

years of theoretical discussions are in the process of

becoming informed by actual laboratory practice and FDA

enforcement. This session will engage the audience in an

interactive panel discussion with analysts from supplement

company’s in-house laboratories, small and large contract

laboratories, an innovative contract research organization,

a botanical supplier dealing with FSMA requirements, and

regulatory experts. The discussion is expected to be free-

wheeling and will range from identity testing requirements,

“reasonably anticipated contaminants”, standard operating

procedures, “verification or validation”, and qualification

of standards and reference materials. The ultimate goal of

the session is to put manufacturers and contract labs in the

same room so that contract labs can provide a breakdown

of tests available and the average resources necessary

to perform, manufacturers can provide a realistic picture

of their available resources, and for regulatory experts to

comment on the mandates of the regulation as related to

resources.
