This Common Plant Could Be an Unexpected New Source of Protein

Researchers found that dried pot marigold flowers can yield a plant protein with unusual heat stability, umami-related amino acids, and strong emulsifying power.

The findings suggest marigold protein could work as a functional ingredient in plant-based foods such as dressings and baked goods.

If scaled successfully, this could turn an overlooked agricultural byproduct into a sustainable, high-value protein source.
