Unveiling the Diversity of Non Conventional Proteins - From Sources, Extraction, Technofunctionality, Nutraceutical Potential to Advancement in Food Applications - A Systematic Review

Food security, dietary needs and population expansions focused use of non-conventional food components in their diet. Non conventional proteins have gained attention due to their unique properties, diverse sources and consumer acceptability. The systematic review related to non conventional proteins provide a state-of-the-art from a decade of research on sources, chemistry, extraction strategies, nutraceutical potentials, development of future foods and their potential in food sectors, including bakery, meat and fish industry. Key findings from this systematic review underscore non-conventional protein’s promising potential in addressing current sustainability challenges, food security and human health. Moreover, the study identifies research gaps and future directions to facilitate non-conventional protein commercialization and widespread adoption. The non-conventional proteins have the potential to develop a protein-rich diet from insects, microbial, and cultured meat-based proteins to meet the global demand for protein-rich foods. In conclusion, this systematic review comprehensively examines non-conventional proteins, shedding light on their sources, extraction methods, and potential applications. The findings contribute knowledge related to non-conventional protein sources and offer valuable insights for researchers, interested in harnessing the benefits of these novel protein sources.
