DuPont Nutrition & Biosciences launches newest alpha amylase enzyme

In Delaware, DuPont Nutrition & Biosciences announced the launch of SPEZYME HN, the latest in the SPEZYME line of alpha amylase enzymes and a new inclusion in business’s suite of XCELIS Ethanol Solutions.

The SPEZYME line is known for offering numerous advantages for ethanol producers, including robust liquefaction and significant viscosity reduction across a variety of temperatures and pH levels. For the new SPEZYME HN blend – which combines an alpha-amylase with a thermostable phytase – that means delivering industry-leading liquefaction for dry grind ethanol plants operating under harsh conditions.

SPEZYME HN generates high dextrose equivalents (DEs) and starch solubility when liquefaction cation concentrations are far below the industry average. In fact, it produces higher DEs and lower slurry viscosity than competitive alpha-amylases at liquefaction temperatures up to 195 degrees Fahrenheit.
