Perfect Day

Perfect Day is a food technology company founded in 2014 and based in Berkeley, California, United States. It was formed to reduce the environmental footprint of dairy protein production, which traditionally requires raising cattle for milk.

The company uses precision fermentation, feeding microorganisms with sugars so they express a dairy-identical whey protein without animal input, marketed under the ProFerm brand. Perfect Day supplies this protein as an ingredient to food and beverage manufacturers; its technology was the first precision-fermentation dairy protein to receive FDA regulatory clearance, with commercial-scale deliveries planned from a joint manufacturing facility with Zydus Lifesciences in India.

1. Precision fermentation: microorganisms are engineered to produce whey protein identical to cow's milk protein.

2. ProFerm ingredient line: recombinant beta-lactoglobulin whey protein supplied to food manufacturers.

3. Regulatory clearance: first company to receive FDA approval for a precision-fermentation dairy protein.

4. Lower footprint: the company reports up to 97 percent fewer emissions than conventional dairy protein.

5. Brand partnerships: protein used by third-party brands under the Made with Perfect Day program.

6. Scale-up manufacturing: joint facility with Zydus Lifesciences in Gujarat, India for commercial deliveries.
