Harnessing the Potential of Industrial Hemp in Food

Summary: Enhancing confidence in hemp-based foods requires reducing harmful compounds like psychoactive elements, allergens, and anti-nutrients. 

FREMONT, CA: Hemp, a versatile and valuable crop, holds significant potential across various industries, including foods, textiles, and pharmaceuticals. In recent years, the utilization of hemp in the food sector has surged, driven by its numerous health benefits and versatile applications. This comprehensive review delves into the scientific literature exploring the role of industrial hemp in the food industry. It analyzes historical context, recent food industry applications, health advantages, development challenges, and the global outlook for hemp-based food products. The findings underscore the growing consumption of hemp in foods and as food ingredients. Hemp-based foods, marketed for their health benefits, exhibit varying degrees of success among consumers. Concurrently, research in hemp-derived foods has witnessed a substantial surge, with in vitro and in vivo studies illuminating their potential health perks. This trend indicates a promising trajectory for innovative novel foods derived from industrial hemp. However, integrating hemp into foods necessitates rigorous regulatory compliance due to health concerns tied to THC (tetrahydrocannabinol) to ensure product safety before consumption.

Of particular interest in the food realm is industrial hemp containing THC levels below 0.3 percent, according to research published in Taylor & Francis Online. Renowned for its nutritional composition, hemp has gained traction as a nutritious product. The plant's seeds, flowers, and leaves are deemed valuable components with potential applications in the food industry. Among these, hemp seeds stand out as a nutritionally comprehensive food source. Available whole, hulled, or dehulled hemp seeds have sparked interest in various processing techniques, such as germination, to modify their phytochemical profile. Hemp sprouts, enriched in specific phytochemicals, have also garnered nutritional attention in the context of hemp-derived foods.

Transforming hemp into food products poses challenges for food processors and nutrition specialists. Obstacles span sensory attributes, including the bitter taste, unusual color, and unappealing viscosity of hemp-derived products. These factors impede consumer palatability. Innovations in processing techniques are gradually addressing these challenges, with flavor-bearing ingredients employed to counter the bitter taste, resulting in more appealing hemp oil products.

Beyond sensory hurdles, public perception casts a shadow over the adoption of hemp in foods, largely stemming from its association with marijuana. The two plants share the same species, Cannabis sativa, linked to psychoactive elements. Unfounded concerns about hemp's potential to induce drug addiction hinder its acceptance. Addressing this requires improved communication, education, and technological influence to reshape public opinion of hemp-based foods.

The developing demand for hemp as a food ingredient confronts legal challenges as it emerges from the shadow of Cannabis prohibition. Additionally, anti-nutrients present in hemp, such as phytic acid, condensed tannins, and saponins, limit its use in foods or supplements. While some exhibit positive health impacts, these compounds are considered undesirable due to their negative effects. Moreover, while hemp is generally low-allergenic, there are reports of mild symptoms induced by its derived products, particularly proteins.
