Carbohydrate Check Sample Program (CCSP)

A carbohydrate check sample program for the corn refining industry and users of refined corn products:

  • 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.

The Program

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

  1. High Fructose Corn Syrup
  2. Corn Syrup
  3. Corn Starch
  4. Coproducts (gluten meal, gluten feed, germ, and occasional corn samples)

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. A statistical report, based on all test results, is generated and returned to subscribers so they can compare their own results with aggregate laboratory performance.

For each sample, a standard list of primary tests is requested, plus two or three secondary tests, which may vary. 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.

Online Results Reporting

Participants are able to submit their individual laboratory results and view the aggregated results online through a secure Web site dedicated specifically to this program.

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.
