What to know about Protein-enriched ketchup gets boost from algae extracts

Researchers have developed a protein-enriched tomato ketchup using extracts from the microalgae Chlorella vulgaris. Taste tests indicated that concentrations up to 3% were acceptable to consumers, providing increased protein, amino acids, and minerals without significantly altering the flavor or appearance.

What happened

Protein-enriched ketchup gets boost from algae extracts Lisa Lock Scientific Editor Alexander Pol Deputy Editor Added protein is showing up in foods from breakfast cereal to pasta, but not many condiments … yet.

Why it matters

Researchers have now developed an enriched tomato ketchup by incorporating protein extracted from algae.

Common ground

A panel of taste testers preferred recipes containing up to 3% added algal extract, saying the samples maintained the sweet, tangy taste and reddish appearance expected of the condiment.
