2015 Carbohydrate Check Sample Program

Now Registering for the 2015 Carbohydrate Check Sample Program

Registrations for the 2015 Carbohydrate Check Sample Program can be submitted online between now and January 8, 2015. This is a one-time registration, and after January 8, registrations will be closed for the year.

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.

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:

  1. High Fructose Corn Syrup
  2. Corn Syrup
  3. Corn Starch
  4. Co-Products
  5. Dry Citric Acid
  6. Dry Maltodextrin

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, follow the link on the right hand side of this page to fill out a form indicating the sample(s) requested, billing and shipping addresses, payment information, and a valid email address. Please note, we are no longer accepting payment via credit card. Payment can be made via wire transfer, EFT or check.

How is my payment amount calculated?

Pricing for the CCSP is based on two factors: sample type and shipment. Participants will be charged a flat fee for each sample type they sign up for. In 2015, the price for each sample type is as follows:

Product Cost Per Sample Cost for All Series
High Fructose Corn Syrup $58 $465
Corn Syrup $58 $465
Corn Starch $50 $400
Co-products $50 $400
Maltodextrin $50 $400
Citric acid $50 $400

Then, participants will be charged for the cost of shipping samples to their destination. U.S. participants are charged a fee of $9 per shipment, while international participants’ shipping costs vary based on location.

International participants paying by wire transfer will be charged an additional fee of $25 to cover fees associated with those transactions.

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

Participants will be emailed a confirmation of their enrollment and an invoice once the registration is received. Note both the shipping and billing contacts entered on the registration form will receive the confirmation. 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 2015 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. CRA Analytical Methods are available online at http://www.corn.org/publications/industry-resources/analytical-methods.

Once the results for the requested tests are known, they should be entered into the Quickbase system.

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.
