Frequently Asked Questions

What is the Carbohydrate Check Sample Program?

The CRA Carbohydrate Check Sample Program (CCSP) is designed for the corn refining industry and users of refined corn products. It allows laboratories testing corn wet-milled products to compare the precision of their testing methods with the performance of other labs doing the same types of analysis. Validation through a check sample program offers an important tool in maintaining analytical accuracy.


What should a participant do once results are known?

Results should be entered into the Quickbase system.

Who should participate in the CCSP?

Facilities that make or use products from the corn refining industry would benefit from this program.


How does it work?

Subscribers can participate in any or all of the six check sample series listed below:

High Fructose Corn Syrup 42, 55
Corn Syrup 36DE, 42DE, 63DE, high Maltose
Corn Starch Regular, Acid Thinned, Bleached, Cationic
Co-Products Whole corn, 60% Corn Gluten Meal, Corn Germ Meal, 21% Corn Gluten Feed
Dry Citric Acid Anhydrous
Dry Maltodextrin 5DE, 10DE, 18DE, High Maltodextrin Corn Syrup

For each series, subscribers receive product samples (from a variety of refining companies) at regular intervals, analyze them according to an established series of tests, and report their results via an online website. A statistical report, based on all test results, is generated and made available to subscribers online so that they can compare their own results with aggregate laboratory performance.


How can a facility sign up for the program?

To register for the program, participants should first click the “Place an Order” button above. Then select their Carbohydrate Sample from the options. At checkout, participants will be prompted to fill out a form indicating the sample requested, billing and shipping addresses, payment information, and a valid email address. Finally, participants can select their payment method (Credit Card/EFT/Wire Transfer or Check).


What can I expect once a facility is registered for the program?

Participants will be emailed a confirmation of their enrollment receipt and an invoice (if paying by Credit Card/EFT/Wire Transfer or Check) once the registration is received. Once enrolled in the program, subscribers will receive samples every six weeks starting in mid-January. Participants will receive information on logging into the Quickbase system for results entry at approximately the same time as the participant’s first samples are shipped. Results will be due four weeks from the day the samples are mailed out. The 2016 schedule is available here:

What should a participant do with the samples?

Participants should conduct the tests listed on the results sheet mailed with the samples or provided in advance via email. All tests should be done using the Corn Refiners Association’s (CRA) Analytical Methods or other specified methods. Analytical Methods are available at CRA online.


When are the results available?

Participants will receive an email when the aggregated results for a series are available online. In general, the reports become available shortly before the next series of samples is shipped.

Independent consultant Silliker Inc. administers the online results reporting and this is done on a strictly confidential basis to ensure there is no disclosure of individual company test results.
