Plant-Based Protein for the People

April 14, 2023

While plant-based proteins have been part of humanity's diet for centuries, it wasn't until the advent of the original textured vegetable protein (TVP) in the 1960s that it started becoming a viable replacement for animal-based protein sources in more mainstream diets. The first commercially available plant-based proteins would not be mistaken for animal-based protein sources and were largely of interest only to vegans, vegetarians, and pescatarians. 

Things have changed dramatically in the plant-based protein sector, especially in the last ten years. Meat-substitutes that looked, smelled, felt, and tasted similar to meat swept the market, and in an age where consumers are becoming more and more informed and interested in sustainability and stewardship of the planet, plant-based protein has risen as a viable alternative for about one in four consumers, those who consider themselves flexitarians.

Kjeldahl vs Dumas: Modern Protein Analysis

June 3, 2022
