The trend toward organic cotton is growing rapidly.

Time and again, genetically modified cotton is labeled with certifications that skip laboratory tests or only take random seed samples.

Prove that your organic cotton is not genetically modified.

Hohenstein has developed molecular biological detection systems especially for cotton products. We cover all aspects of the supply chain, from raw cotton to yarns and fabrics to end products. Manufacturers, brands, certifiers and consumer protection organizations benefit from clear yes / no results for GMO-free cotton products.

Common Certifications

Hohenstein Method

Two steps to 100% certainty with the Hohenstein Method.

  • The sample is crushed and cotton fibers are mechanically and enzymatically extracted. The genetic material (DNA) is separated from the fibers and purified through a multi-stage process.
  • If the DNA contains a specific target sequence (gene marker), genetic modification is indicated and molecular biological evidence is obtained. Control reactions serve to verify unaltered cotton DNA and exclude false-negative results.

DNA is generally protected in the nucleus of the cotton fiber. In some cases (eg. heavily processed cotton where no more DNA is available), DNA analysis does not work for end products. In this case, processing can be retraced and the raw materials can be tested instead.

Benefits.

  • Product optimization
  • Product identification
  • Marketing claim verification
  • Protection against piracy
  • Quality control

Organic cotton with confidence.

The traceability of GMO-free cotton across the entire textile supply chain.

There are several steps between the field and the consumer.

Each step has the potential to add toxins or increase the product's footprint.

Hohenstein's GMO test method is used by STANDARD 100 by OEKO-TEX® to keep people safe from harmful substances that could be left on organic cotton products during production.

MADE IN GREEN by OEKO-TEX® is a traceable label that protects workers and the planet - in addition to the consumer. It verifies the responsible production throughout the supply chain.
