Hempseed as a nutritious and healthy human food or animal feed source: a review

Abstract

Summary Hempseed products are projected to receive great potentials due to the rapid growth in the US market. Industrial hemp has been an important crop for food, fibre and medicine applications. Hempseed products can be used as nutraceutical supplements and functional foods for human and can be applied for animal feed. This review provides a comprehensive summary of nutritional quality and health benefits of hempseed which is attributed to high levels of essential fatty acids and other PUFAs in the oil, with a rich source of essential amino acids in highly digestible protein. This review examines the impact of extraction methods on oil yield and bioactive compounds, nutrition value, and food application of hemp protein‐extracted products, including meal, protein isolate and protein concentrate. Recent research related to the understanding chemical composition, nutritional value, health benefits, processing impact, functional properties of hempseed products, and their application for food and feed is presented.

Application of Raw and Defatted by Supercritical CO2 Hemp Seed Press-Cake and Sweet Grass Antioxidant Extract in Pork Burger Patties

“…Hemp inflorescences biosynthesise quite unique health beneficial phytocannabinoids, while hemp seeds are an excellent source of high-value oil, proteins, and valuable micronutrients [6], including health beneficial bioactive compounds [7,8]. For instance, Pihlanto et al [9] reported 5.88-10.63 mg total phenolic content (expressed in mg of gallic acid equivalents) per gram of dry defatted hemp seed flour, which was also confirmed by Rea et al [10].…”

“…The same tendency may be observed in the samples with RH, while in the case using RH with SG, the effect of hemp seed press-cake may be explained by its water-binding capacity. Raikos et al [31], Xu et al [6], and Zając et al [32] reported that hemp protein or hemp flour with high protein content improves the products' water holding capacity. Therefore, the lower grilling losses with hemp additives may be useful for producers to help retain the moisture inside the product.…”

Identification and Characterization of the Seed Storage Proteins and Related Genes of Cannabis sativa L.

“…Industrial hemp ( C. sativa L. supsp. sativa ), generally refer to hemp, has <0.3% of tetrahydrocannabinol (THC), a higher plant height, and the main parts used are seeds and fiber ( 2 ). Owing to its low THC content, industrial hemp is unable to stimulate human nerves, therefore, has a potential to be grown as a safe crop ( 3 ).…”

Commercial Hemp Seed Oils: A Multimethodological Characterization

“…Only in recent times the discovery of hemp seeds' high nutritional value led to a revaluation of this source for human consumption. Literature regarding the investigation of hemp seeds' composition has increased, making them an emerging source for value-added functional food ingredients and nutraceuticals [5,6]. Hemp seeds are consumed shelled in salad dressings, and in the production of snack bars, or they can be cold pressed to obtain edible hemp seed oil, and the residual cake is grinded to have a fiber-rich flour used in processed food (such as bread, biscuits, and pasta).…”
