Hempseed Oil - 32 oz.
Hempseed Oil - Unrefined - 32 oz.
Hemp oil or hempseed oil is obtained by pressing hemp seeds. Cold pressed, unrefined hemp oil is dark to clear light green in colour, with a pleasant nutty flavour. The darker the colour, the grassier the flavour.
Refined hempseed oil is clear and colourless, with little flavour and lacks natural vitamins and antioxidants. Refined hempseed oil is primarily used in body care products. Industrial hempseed oil is used in lubricants, paints,inks, fuel, and plastics. Hempseed oil has found some limited use in the production of soaps, shampoos and detergents. The oil is of high nutritional value because its 3–1 ratio of omega-6 to omega-3 essential fatty acids, which matches the balance required by the human body.It has also received attention in recent years as a possible feedstock for the large-scale production of biodiesel. There are a number of organisations that promote the production and use of hempseed oil.
Hempseed oil is manufactured from varieties of Cannabis sativa that do not contain significant amounts of THC, the psychoactive element present in the cannabis plant. This manufacturing process typically includes cleaning the seed to 99.99% before pressing the oil. There is no THC within the hempseed, although trace amounts of THC may be found in hempseed oil when plant matter adheres to the seed surface during manufacturing. The modern production of hempseed oil, particularly in Canada, has successfully lowered THC values since 1998.
About 30–35% of the weight of hempseed is an edible oil that contains about 80% as essential fatty acids (EFAs); i.e., linoleic acid, omega-6 (LA, 55%), alpha-linolenic acid, omega-3 (ALA, 22%), in addition to gamma-linolenic acid, omega-6 (GLA, 1–4%) and stearidonic acid, omega-3 (SDA, 0–2%).
The proportions of linoleic acid and alpha-linolenic acid in one tablespoon per day (15 ml) of hempseed oil easily provides human daily requirements for EFAs. Unlike flaxseed oil, hempseed oil can be used continuously without developing a deficiency or other imbalance of EFAs. This has been demonstrated in a clinical study, where the daily ingestion of flaxseed oil decreased the endogenous production of GLA.
In common with other oils, hempseed oil provides 9 kcal/g. Compared with other culinary oils it is low in saturated fatty acids.
Highly unsaturated oils, and especially poor quality oils, can spontaneously oxidize and turn rancid within a short period of time when they are not stored properly; i.e., in a cool/cold, dark place, preferably in a dark glass bottle. Hempseed oil can be frozen for longer periods of storage time. Preservatives (antioxidants) are not necessary for high-quality oils that are stored properly.
Hempseed oil has a relatively low smoke point and is not suitable for frying. Hempseed oil is primarily used as a food oil and dietary supplement, and has been shown to relieve the symptoms of eczema (atopic dermatitis).
