“…HS oil is a rare fount of nourishment for human diet, in particular for vegetarians, because of their unique reported ratio in ω-6/ω-3, most represented by linoleic acid (LA; 18:2, n-6) and α-linolenic acid (ALA; 18:3, n-3) [39]. The optimum ratio is approximately 2.5:1-3:1, also recommended for human nutrition [40].…”

Although hemp seed (HS) oil is characterized by more than 80% polyunsaturated fatty acids (PUFAs), a very high ω-6-to-ω-3 ratio is not a popular commodity. The aim of this work was to provide useful data about the bioactive components and cannabidiolic acid content in thirteen different commercial hemp seed oils. The investigated HS oils showed a good ω-6/ω-3 ratio, ranging from 1.71 to 2.27, massively differed in their chlorophylls (0.041–2.64 µg/g) and carotenoids contents (0.29–1.73 µg/g), as well as in total phenols (22.1–160.8 mg Gallic Acid Equivalents (GAE)/g) and tocopherols (3.47–13.25 mg/100 g). Since the high content of PUFAs in HS oils, photo-oxidative stability was investigated by determining the Thiobarbituric Acid Reactive Substances (TBARS) assay and extinction coefficient K232 and K270 after the photo-oxidative test. The percentage of increase in K232 and K270 ranged from 1.2 to 8.5% and from 3.7 to 26.0%, respectively, indicating good oxidative stability, but TBARS showed a 1.5- to 2.5-fold increase in oxidative behavior when compared to the initial values. Therefore, the diversity in bioactive compounds in HS oils, and their high nutritional value, suggest the need for a disciplinary booklet that well defines agronomic and post-harvest management conditions for achieving a good food objective.

“…There are numerous methods for extraction of hemp seed oil, including cold press, supercritical CO 2 extraction, solvent extraction with isopropanol, hexane, dimethyl ether, and numerous pretreatments. However, all of these methods possess different advantages and disadvantages depending on the end use of the product and the extraction fraction in question [ 138 ].…”

“…Considering an initial economic cost-benefit analysis, supercritical CO 2 extraction is most efficient, followed by Soxhlet extraction and ultrasonication [ 138 ]. In terms of scale-up extraction, ultrasonication and Soxhlet extraction are the best methods, while the desirable omega-6 PUFA/omega-3 PUFA ratio can be achieved by the Soxhlet extraction method [ 138 ]. Selecting the most appropriate method of extraction depends on the end use and desired bioactives in the final products.…”

Industrial Hemp (Cannabis sativa subsp. sativa) as an Emerging Source for Value-Added Functional Food Ingredients and Nutraceuticals

Industrial hemp (Cannabis sativa L., Cannabaceae) is an ancient cultivated plant originating from Central Asia and historically has been a multi-use crop valued for its fiber, food, and medicinal uses. Various oriental and Asian cultures kept records of its production and numerous uses. Due to the similarities between industrial hemp (fiber and grain) and the narcotic/medical type of Cannabis, the production of industrial hemp was prohibited in most countries, wiping out centuries of learning and genetic resources. In the past two decades, most countries have legalized industrial hemp production, prompting a significant amount of research on the health benefits of hemp and hemp products. Current research is yet to verify the various health claims of the numerous commercially available hemp products. Hence, this review aims to compile recent advances in the science of industrial hemp, with respect to its use as value-added functional food ingredients/nutraceuticals and health benefits, while also highlighting gaps in our current knowledge and avenues of future research on this high-value multi-use plant for the global food chain.
