Hemp seed as an emerging source of nutritious functional ingredients.

Abstract

Industrial hemp (Cannabis sativa L.), cultivated for its low THC content (<0.3%), is increasingly valued for its nutrient-rich seeds and broad applications in human nutrition. This review offers a holistic analysis of hemp seed utilization, covering agronomic, nutritional, processing, and economic aspects. Agronomic practices and environmental factors considerably influence the seed's nutritional profile, which includes high levels of complete proteins, essential fatty acids with an optimal ω-6 to ω-3 ratio, dietary fiber, and micronutrients. Hemp seeds also contain bioactive compounds with antioxidant and anti-inflammatory properties providing further health benefits and economic value. Advancements in processing methods, such as germination, fermentation, and cold pressing have enhanced nutrient bioavailability and reduced antinutritional factors, supporting the development of functional foods. Economically, the hemp seed market shows strong growth potential, driven by consumer demand for plant-based, sustainable food sources. However, challenges persist in scaling production and standardizing quality across supply chains. Hemp seeds represent a sustainable, nutrient-dense food ingredient with momentous potential to support health and diversify agricultural economies. Continued interdisciplinary research and supportive policy frameworks are essential to unlock their full value in the human diet.
