Hypothesis

Can enzymatic corn wet milling be more cost-effective and environmentally friendly compared to conventional methods?

Conclusion

The E-milling process is cost competitive with conventional methods, especially during periods of high corn prices, due to enhanced product yields.

Supporting Evidence

  • The E-milling process reduces sulfur dioxide usage significantly.
  • Enzymatic treatment shortens steeping time from 36 to 6 hours.
  • The model predicts a reduction in capital costs for E-milling compared to conventional methods.

Takeaway

This study shows that using enzymes to process corn can save money and be better for the environment compared to traditional methods.

Methodology

The study developed a process model using SuperPro Designer® to simulate the E-milling process and analyze costs.

Limitations

The model's predictions are based on specific economic conditions and may not apply universally.
