The Seed of Industrial Hemp ( Cannabis sativa L.): Nutritional Quality and Potential Functionality for Human Health and Nutrition

nutrients-logo“Hempseeds, the edible fruits of the Cannabis sativa L. plant, were initially considered a by-product of the hemp technical fibre industry. Nowadays, following the restorationing of the cultivation of C. sativa L. plants containing an amount of delta-9-tetrahydrocannabinol (THC) <0.3% or 0.2% (industrial hemp) there is a growing interest for the hempseeds production due to their high nutritional value and functional features.

The goal of this review is to examine the scientific literature concerning the nutritional and functional properties of hempseeds. Furthermore, we revised the scientific literature regarding the potential use of hempseeds and their derivatives as a dietary supplement for the prevention and treatment of inflammatory and chronic-degenerative diseases on animal models and humans too.

In the first part of the work, we provide information regarding the genetic, biochemical, and legislative aspects of this plant that are, in our opinion essential to understand the difference between “industrial” and “drug-type” hemp. In the final part of the review, the employment of hempseeds by the food industry as livestock feed supplement and as ingredient to enrich or fortify daily foods has also revised.

Overall, this review intends to encourage further and comprehensive investigations about the adoption of hempseeds in the functional foods field.”

Whole blood transcriptome analysis in ewes fed with hemp seed supplemented diet.

Image result for scientific reports “The hemp plant (Cannabis sativa L.) has a long tradition of being used for many different purposes such as industry, medicine and nutrition. In particular, because hemp seed (HS) is rich in oil protein and considerable amounts of dietary fiber, vitamins and minerals that are particularly suitable also for animal nutrition.

Different studies have evaluated HS on qualitative and quantitative properties of livestock products but as of today, nobody has investigated the molecular pathway behind HS supplementation in farm animals. Thus, in this study, we will report the first RNA sequencing of the whole-blood transcriptome of ewes fed either with a controlled diet (CTR, n = 5) or with a diet supplemented with 5% of hemp seed (HSG, n = 5).

These results indicate that HS supplementation positively affects the energy production pathway in lactating ewes conferring them also more resistance to adverse climatic conditions such as low temperature. Finally, the higher milk lactose content makes the derived dairy products more profitable.”

“In conclusion, in this study, we have assessed the transcriptome signature induced by 5% hemp seed supplemented diet in ewes. The findings suggest that pathways related to energy production were the most affected. In addition, we found that this condition could also be potentially beneficial for adaptation to low temperatures. Moreover, we found a higher content of lactose, which makes the derived dairy products more profitable.”

The effect of hemp seed and linseed addition on the quality of liver pâtés.

Image result for Acta Scientiarum Polonorum Technologia Alimentaria “Liver p&acirc;t&eacute;s are popular all over the world, but they usually contain high amounts of animal fats. It may be beneficial to improve their dietetic value by decreasing the saturated fatty acid content, while maintaining their sensory quality. One way to do this is to add ingredients which are rich in polyunsaturated fatty acids, such as hemp seed or linseed. Hemp seeds are valuable because of their fat and protein content and linseed is known for its high &alpha;-linolenic fatty acid (ALA) content. Both are good sources of fiber.

RESULTS:

The addition of hemp and linseed increased the fat content. The fatty acid profile improved signifi- cantly. There were more polyunsaturated fatty acids and the n-6 to n-3 ratio was reduced in both products containing oil seeds compared to the control sample, which is important from the health point of view. The color parameters were not changed. The hardness, chewiness and adhesiveness increased in products contain- ing oil seeds. Those products received higher scores in sensory analysis.

CONCLUSIONS:

The quality of the p&acirc;t&eacute;s with added oil seed is comparable to or better than the traditional ones. The products with both hemp and linseed can be treated as a good source of n-3 fatty acids. The amount of ALA is high enough to label the product as a source of n-3 fatty acids.”
