Technical approach

As reported

Precision fermentation

Engineering microbes to make dairy proteins

Perfect Day genetically engineers Trichoderma reesei fungus to produce beta-lactoglobulin, the main whey protein in milk.

ProFerm protein

Molecularly identical to dairy

ProFerm emits 91-97% fewer emissions, uses 29-60% less energy, and consumes 96-99% less water than conventional dairy whey.

B2B ingredient supplier

Selling to food and beverage makers

Perfect Day supplies bulk ProFerm to CPG companies that incorporate it into their branded products rather than selling directly to consumers.
