Gap Analysis of Metabolic Conversions of Off-Flavors and Antinutrients in Plant-Based Substrates. [PDF]

Compr Rev Food Sci Food Saf
ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...
