SigNature T DNA technology will be rolled out to cotton gins in Arkansas, California and Texas

Product authentication business Applied DNA Sciences (APDN) is rolling out its SigNature T DNA technology to cotton gins in Arkansas, California and Texas, to help improve cotton supply chain transparency. 

The company is also expanding its US cotton tagging business by 50m pounds as part of its new HomeGrown Lonestar programme within the 2016 US cotton harvest.

The expansion of the SigNature T cotton tagging is being enabled thanks to new, fully automated DNA transfer systems that are equipped with real-time monitoring, security and data capture, ensuring efficient and consistent DNA tagging of cotton fibres during the ginning process, when cotton fibres are separated from seeds.

The new DNA transfer systems are designed to handle higher volumes of SigNature T tagging, including an increase of 50m pounds of HomeGrown Lonestar and 10m  pounds of HomeGrown Acala upland cottons. Gins trained and certified in SigNature T will apply the technology for the October harvest, helping ensure traceability from "source to shelf." 

"We provide certainty to a very complex textile supply chain," says Dr James Hayward, president and CEO of Applied DNA Sciences. "We offer an end-to-end platform that enables users to stay one step ahead. In just one DNA tagging campaign, entire companies and countries can be certain that their reputations for quality, integrity, and sustainability are preserved, from the source all the way to the shelf."

The track-and-trace process continues through the supply chain, with fibre, yarn and fabric sample genotyping, and SigNature T DNA tagging and authentication managed through the DigitalDNA textiles portal.

According to the company, a forensic and data-driven approach for assuring quality and label compliance will continue to reduce reliance on paper documentation, which often is not sufficient to prove origin or to substantiate label claims.

In the end, retailers, manufacturers and consumers will now know that the final product comes from the same cotton that left the gin at the beginning of the supply chain, says Applied DNA.

The new Transfer Systems will also allow a higher volume of tagging, including the new Lonestar and Acala upland cotton programmes.

Additing this to existing DNA tagging for Pima (known as PimaCott), and to HomeGrown Upland programmes that previously included Acala and Delta cottons means the full variety spectrum is now covered. Adoption has already begun with merchants, ginners, manufacturers and retailers in India, Pakistan, Bangladesh, China, Turkey and the US, the company says. 

In August, the company announced it is working with the BLC Leather Technology Centre (BLC) on DNA-tagged animal pelts that will help improve leather supply chain transparency.
