Unveiling the Potential of Leaf Proteins

Protein deficiency is one of the major nutritional problems in the developing world. Increasing population in both emerging and developed markets want inexpensive, sustainable, and nutritional protein. Health attributes with a particular focus on increased consumption of plant-based proteins are estimated at USD 14.3 billion in 2024 and projected to grow at a CAGR of 7.5% by 2029. Therefore, aims to identify “new” and reasonably priced sources of plant protein from green leaf biomass. The main protein in green leaves is Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase), which is the most abundant protein in nature. It has good amino acid profile, ranking better than other plant proteins (Anon, 2024; Balfany et al., 2023; Ghaly and Alkoaik, 2010; Andersson and Backlund, 2008).
