Valicor acquires patent covering protein extraction from corn ethanol stillage

Fluid recovery and regeneration solutions specialist Valicor has completed the acquisition of a patent that covers the extraction of protein from corn ethanol stillage and is designed to help ethanol producers maximise their coproduct recovery and value.

The patent for invention number 7,829,680 is for a system and method that isolates gluten (protein) as a coproduct of the ethanol production. The protein product can be dried to produce a high value, high protein meal.

'This latest patent complements our VFRAC stillage optimisation platform. Working together, these technologies transform protein product so it's easier to recover and has higher digestibility ratios and enhanced flow characteristics," says Phil Schoof, senior VP of separation technologies at Valicor. 'This IP is a cornerstone patent on protein extraction from corn ethanol stillage, it has the earliest priority date of any technologies in the space, and the technology has been proven on commercial scale.'

With this patent and its patented VFRAC stillage optimisation platform, Valicor moves aggressively into an early adopter role in the development of backend, post distillation coproduct recovery technologies. These technologies are the first of their kind and are designed to optimise the overall plant efficiency, productivity and profitability through high value coproduct diversification.
