Hemp Seed oil
The oil extracted from hempseeds is rich in polyunsaturated fatty acids, especially linoleic (omega-6) and omega-linolenic (omega-3) acids with a desirable ratio between 2:1 and 3:1 for optimal health.
Hempseed oil is an especially rich source of the two Esential Fatty Acids, linoleic acid (18:2 omega-6) and alpha-linolenic acid (18:3 omega-3), in addition to their respective biologic metabolites, gamma-linolenic acid (18:3 omega-6, ‘GLA’) and stearidonic acid (18:4 omega-3, ‘SDA’).
The myriad of benefits reported to be attributable to omega-3 polyunsaturated fatty acids (PUFA) include anticancer, anti-inflammatory, and anti-thrombotic properties. In addition, dietary omega-3 PUFA help to increase general metabolic rates and promote the burning of fat.
Although the levels of CBD and terpenes within the oil are typically small, many health benefits may still be gained from its presence.
Natural products such as beta-sitosterol and methyl salicylate complement the nutritious value of hemp seed oil and increases its effectiveness as a functional food.
Hempseed protein has been well known for its excellent digestibility and desirable essential amino acid composition. Because of the high nutritional value, hempseed protein has drawn increasing attention in scientific research. Of particular interest is the purported health benefit of bioactive peptides prepared from hemp protein as well as its technological functionality, such as foaming, emulsifying, gelling, and film-forming capabilities.
Hemp protein contains an exceptionally high amount of arginine and glutamine: Arginine accounts for approximately 12% of hempseed protein when compared with less than 7% for most other food proteins, including the proteins from potato, wheat, maize, rice, soy, rapeseed, egg white, and whey (Callaway, 2004).
Whole hempseeds contain 25% to 35% oil, 20% to 25% protein, 20% to 30% carbohydrates, 10% to 15% insoluble fibers, and vitamins and minerals such as phosphorus, potassium, magnesium, sulfur, calcium, iron, and zinc.
After removal of the hull, the edible portion of the seeds contains, on average, 46.7% oil and 35.9% protein. The concentration of antinutritional compounds, such as phytic acid, condensed tannins, and trypsin inhibitors, is very low in hempseeds.
