ASTM International develops standard for measuring corn kernel fiber conversion

January 14, 2026 |

In Pennsylvania, ASTM International has developed a standard (E3503) that will address a specific need in the ethanol industry: measuring corn kernel fiber conversion for various applications, including regulatory pathways. The standard was developed by the biomass conversion subcommittee (E48.05), part of ASTM’s bioenergy and industrial chemicals from biomass committee (E48).

According to ASTM member Tessa Schmitz, the method’s simplicity and safety make it valuable to a wide range of users. Laboratories and industries seeking to measure hemicellulosic sugars—such as those in sustainability, food, beverages, and baking—will find it useful.

Schmitz adds that the method avoids the hazards and specialized equipment demands of traditional acid hydrolysis techniques, making it safer and more accessible. It was designed with a dual focus: delivering high-quality results while minimizing technician time and touchpoints, making it ideal for commercial testing environments.
