The FDA raised no questions about Onego Bio's conclusion that Bioalbumen, ovalbumin made by the fungus Trichoderma reesei, is generally recognised as safe. That clears it for US use as a protein source and for foaming, gelling and binding in foods such as baked goods, pasta, drinks and desserts.

## Key facts

- Approved levels: 3–35 g of ovalbumin per 100 g of product
- Company figures: 90% protein; 1 kg of powder equals 277 egg whites
- Its Wisconsin plant, due in 2028, is to match the output of 6 million laying hens
