The Future of Protein: Embracing Hemp's Potential

Protein is a fundamental component of the human diet, essential for the growth and repair of cells, particularly those in muscles and bones. Daily intake of protein is crucial for the proper functioning of bodily processes.


When many people think of protein, they might envision bodybuilders consuming powder mixes or large portions of meat. However, it's important to understand that protein is necessary for everyone, not just athletes looking to build muscle mass. A wide array of foods provides protein, making it accessible to all.


Proteins are composed of various amino acids, which are often described as 'the building blocks of life.' Of the approximately 20 different amino acids, the human body can synthesize 11 on its own. These are known as 'non-essential amino acids.' The remaining nine, which the body cannot produce, are called 'essential amino acids' and must be obtained through diet.


Meat is a popular source of protein worldwide, but it is not the only option. Plant-based proteins are increasingly favored for several reasons, including their lower environmental impact. The carbon footprint associated with large-scale livestock farming is significant, contributing to global environmental concerns. In contrast, the production of plant-based proteins generally results in a smaller carbon footprint, making it a more sustainable choice.


The shift from animal-based to plant-based protein sources has led researchers to investigate which plants are most efficient and sustainable for protein production. Soybeans and peas are among the popular plant-based proteins, as are beans, nuts, and whole grains. However, the hemp plant is emerging as a potentially superior source of protein.


The use of hemp seed as a source of human nutrition is not new, with its consumption dating back at least 3,000 years. Nonetheless, efforts to 'optimize' hemp seed for its nutritional value are relatively recent. Unlike other plant-based proteins, hemp faced periods of prohibition, which hindered research and development efforts, particularly in terms of cultivar development and protein solubility.


Recent research conducted by scientists affiliated with Cornell University in the United States delved into the protein content and properties of various hemp cultivars. The study focused on hemp seed protein isolates (HPI) extracted from several commercial hemp strains, a Cornell breeding line, and a commercial hemp heart product. The analysis revealed differences in the ratios of edestin, vicilin, and albumin proteins among the isolates, influencing their solubility and functional properties.


The research findings indicated that cultivars with a higher content of vicilin and albumin proteins exhibited greater protein solubility, which in turn affected the functional properties of HPI. Observations included significant variations in water and oil holding capacities, foam capacity, and foam stability across the different HPI samples.


The correlation between hemp seed protein composition and its functionality, coupled with the exploration of a hemp breeding line, suggests that the targeted development of hemp cultivars could enhance the functional properties of hemp seed protein for use in plant-based foods. Hemp seed protein's versatility makes it suitable for a wide range of products, including butter, milk, powders, and breads. With the increasing demand for organic, plant-based proteins and the expansion of hemp seed research, the future of hemp seed protein appears promising.


Given its sustainability advantages and the potential to overcome the limitations faced by other crops and livestock operations, hemp seed protein could one day become a leading source of nutrition, replacing other popular protein sources.
