104-590: A drying oil in painting and varnishing. Although brown flax seed varieties may be consumed as readily as the yellow ones, and have been for thousands of years, these varieties are more commonly used in paints, for fiber, and for cattle feed. A 100-gram portion of ground flax seed supplies about 2,234 kilojoules (534 kilocalories) of food energy , 41 g of fat, 28 g of fiber, and 20 g of protein. Whole flax seeds are chemically stable, but ground flax seed meal, because of oxidation , may go rancid when left exposed to air at room temperature in as little as
156-465: A gravelly or dry sandy nature. Farming flax requires few fertilizers or pesticides . Within eight weeks of sowing, the plant can reach 10–15 cm (3.9–5.9 in) in height, reaching 70–80 cm (28–31 in) within 50 days. In 2022, world production of raw or retted flax was 875,995 tonnes , led by France with 75% of the total. One of the largest regions in France for flax production
208-504: A nutritional supplement and as an ingredient in many wood-finishing products. Flax is also grown as an ornamental plant in gardens. Moreover, flax fibers are used to make linen . The specific epithet in its binomial name, usitatissimum, means "most useful". Flax fibers taken from the stem of the plant are two to three times as strong as cotton fibers. Additionally, flax fibers are naturally smooth and straight. Europe and North America both depended on flax for plant-based cloth until
260-449: A pigment binder in oil paints , as a plasticizer and hardener in putty , and in the manufacture of linoleum . Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins—which function similarly but resist yellowing. Flax seed and its oil are generally recognized as safe for human consumption. Like many common foods, flax contains small amounts of cyanogenic glycoside , which
312-756: A textile comes from the present-day Republic of Georgia , where spun, dyed, and knotted wild flax fibers found in Dzudzuana Cave date to the Upper Paleolithic , 30,000 years ago. Humans first domesticated flax in the Fertile Crescent region. Evidence exists of a domesticated oilseed flax with increased seed-size from Tell Ramad in Syria and flax fabric fragments from Çatalhöyük in Turkey by c. 9,000 years ago. Use of
364-485: A BMI greater than 27. Another meta-analysis showed that consumption of flax seeds for more than 12 weeks produced small reductions in systolic blood pressure and diastolic blood pressure . A third showed that consuming flax seed or its derivatives may reduce total and LDL-cholesterol in the blood, with greater benefits in women and people with high cholesterol . A fourth showed a small reduction in c-reactive protein (a marker of inflammation) only in persons with
416-510: A body mass index greater than 30. Linseed oil , also known as flaxseed oil or flax oil (in its edible form), is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant ( Linum usitatissimum ). The oil is obtained by pressing , sometimes followed by solvent extraction . Owing to its polymer-forming properties, linseed oil is often blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing , as
468-405: A combine then harvests the seeds similar to wheat or oat harvesting. The plant is pulled up with the roots (not cut), so as to increase the fiber length. After this, the flax is allowed to dry, the seeds are removed, and it is then retted . Dependent upon climatic conditions, characteristics of the sown flax and fields, the flax remains on the ground between two weeks and two months for retting. As
520-765: A further disadvantage, because this fatty acid oxidises and goes rancid quickly, which shortens the storage time. Linola was developed in Australia and introduced in the 1990s with less omega-3, specifically to serve as fodder . Another disadvantage of the meal and seed is that it contains a vitamin B6 ( pyridoxine ) antagonist, and may require this vitamin be supplemented, especially in chickens , and furthermore linseeds contain 2–7% of mucilage (fibre), which may be beneficial in humans and cattle, but cannot be digested by non-ruminants and can be detrimental to young animals, unless possibly treated with enzymes . Linseed meal

#1732775401448624-551: A percentage of total fat , flax seeds contain 54% omega-3 fatty acids (mostly ALA ), 18% omega-9 fatty acids ( oleic acid ), and 6% omega-6 fatty acids ( linoleic acid ); the seeds contain 9% saturated fat , including 5% as palmitic acid . Flax seed oil contains 53% 18:3 omega-3 fatty acids (mostly ALA) and 13% 18:2 omega-6 fatty acids. A meta-analysis showed that consumption of more than 30 g of flax-seed daily for more than 12 weeks reduced body weight, body mass index (BMI), and waist circumference for persons with
676-401: A result of alternating rain and the sun, an enzymatic action degrades the pectins which bind fibers to the straw. The farmers turn over the straw during retting to evenly rett the stalks. When the straw is retted and sufficiently dry, it is rolled up. It is then stored by farmers before extracting the fibers. Threshing is the process of removing the seeds from the rest of the plant. Separating
728-415: A similar oil profile to brown flax seeds and both are very high in omega-3s ( alpha-linolenic acid (ALA), specifically). Flax seeds produce a vegetable oil known as flax seed oil or linseed oil , which is one of the oldest commercial oils. It is an edible oil obtained by expeller pressing and sometimes followed by solvent extraction . Solvent-processed flax seed oil has been used for many centuries as
780-568: A substitute for tallow in increasing marbling . In the US, flax-based feed for ruminants is often somewhat more expensive than other feeds on a nutrient basis. Sheep feeding on low quality forage are able to eat a large amount of linseed meal, up to 40% in one test, with positive consequences. It has been fed as supplement to water buffaloes in India, and provided a better diet than forage alone, but not as good as when substituted with soy meal. It
832-479: A week. Refrigeration and storage in sealed containers will keep ground flax seed meal for a longer period before it turns rancid. Under conditions similar to those found in commercial bakeries, trained sensory panelists could not detect differences between bread made with freshly ground flax seed and bread made with flax seed that had been milled four months earlier and stored at room temperature. If packed immediately without exposure to air and light, milled flax seed
884-418: Is Normandy with nearly one-third of the world's production. Flax is harvested for fiber production after about 100 days, or a month after the plants flower and two weeks after the seed capsules form. The bases of the plants begin to turn yellow. If the plants are still green, the seed will not be useful, and the fiber will be underdeveloped. The fiber degrades once the plants turn brown. Flax grown for seed
936-401: Is a protein -rich feed for ruminants , rabbits , and fish. It is also often used as feed for swine and poultry , and has also been used in horse concentrate and dog food . The high omega-3 fatty acid ( ALA ) content of linseed meal "softens" milk, eggs, and meat, which means it causes a higher unsaturated fat content and thus lowers its storage time. The high omega-3 content also has
988-542: Is added to cattle feed as a protein supplement . It can only be added at low percentages due to the high fat content, which is unhealthy for ruminants. Compared to oilseed meal from crucifers it measures as having lower nutrient values, however, good results are obtained in cattle, perhaps due to the mucilage, which may aid in slowing digestion and thus allowing more time to absorb nutrients. One study found that feeding flax seeds may increase omega-3 content in beef , while another found no differences. It might also act as
1040-416: Is allowed to mature until the seed capsules are yellow and just starting to split; it is then harvested in various ways. A combine harvester may either cut only the heads of the plants, or the whole plant. These are then dried to extract the seed. The amount of weeds in the straw affects its marketability, and this, coupled with market prices, determines whether the farmer chooses to harvest the flax straw. If
1092-554: Is an annual plant . Cultivated flax plants grow to 1.2 m (3 ft 11 in) tall, with slender stems. The leaves are glaucous green, slender lanceolate , 20–40 mm long, and 3 mm broad. The flowers are 15–25 mm in diameter with five petals, which can be colored white, blue, yellow, and red depending on the species. The fruit is a round, dry capsule 5–9 mm in diameter, containing several glossy brown seeds shaped like apple pips, 4–7 mm long. The earliest evidence of humans using wild flax as

#17327754014481144-474: Is considered an inferior protein supplement for swine because of its fibre, the vitamin antagonist, the high omega-3 content and its low lysine content, and can only be used in small amounts in the feed. Although it may increase the omega-3 content in eggs and meat, it is also an inferior and potentially toxic feed for poultry, although it can be used in small amounts. The meal is an adequate and traditional source of protein for rabbits at 8–10%. Its use in fish feeds
1196-465: Is cultivated as a food and fiber crop in regions of the world with temperate climates . In 2022, France produced 75% of the world's supply of flax. Textiles made from flax are known in English as linen , and are traditionally used for bed sheets, underclothes, and table linen. Its oil is known as linseed oil . In addition to referring to the plant, the word "flax" may refer to the unspun fibers of

The regions are named for wheat , which was the main agricultural product in the early history of Australia's development; today, many other crops are also produced. The wheatbelt
1300-477: Is easily over-retted, damaging the fiber. This form of retting also produces quite an odor. Stream retting is similar to pool retting, but the flax is submerged in bundles in a stream or river. This generally takes two or three weeks longer than pond retting, but the end product is less likely to be dirty, does not smell as bad, and because the water is cooler, is less likely to be over-retted. Both pond and stream retting were traditionally used less because they pollute
1352-550: Is extracted from the bast beneath the surface of the stem of the flax plant. Flax fiber is soft, lustrous, and flexible; bundles of fiber have the appearance of blonde hair, hence the description "flaxen" hair. It is stronger than cotton fiber, but less elastic. The use of flax fibers dates back tens of millennia; linen , a refined textile made from flax fibers, was worn widely by Sumerian priests more than 4,000 years ago. Industrial-scale flax fiber processing existed in antiquity. A Bronze Age factory dedicated to flax processing
1404-561: Is gripped by rubber belts roughly 20–25 cm (8–10 inches) above ground, to avoid getting grasses and weeds in the flax. The rubber belts then pull the whole plant out of the ground with the roots so the whole length of the plant fiber can be used. The plants then pass over the machine and is placed on the field crosswise to the harvester's direction of travel. The plants are left in the field for field retting . The mature plant can also be cut with mowing equipment, similar to hay harvesting, and raked into windrows. When dried sufficiently,
1456-512: Is limited. Raw, immature linseeds contain an amount of cyanogenic compounds and can be dangerous for monogastric animals, like horses and rabbits. Boiling removes the danger. This is not an issue in meal cake due to the processing temperature during oil extraction. Flax straw left over from the harvesting of oilseed is not very nutritious; it is tough and indigestible, and is not recommended to use as ruminant fodder, although it may be used as bedding or baled as windbreaks . Flax fiber
1508-433: Is nontoxic when consumed in typical amounts. Typical concentrations (for example, 0.48% in a sample of defatted dehusked flax seed meal) can be removed by special processing. The soils most suitable for flax, besides the alluvial kind, are deep loams containing a large proportion of organic matter . Flax is often found growing just above the waterline in cranberry bogs. Heavy clays are unsuitable, as are soils of
1560-428: Is produced when retting, and it would corrode the metal. If the water temperature is kept at 27 °C (80 °F), the retting process under these conditions takes 4 or 5 days. If the water is any colder, it takes longer. Scum collects at the top, and an odor is given off the same as in pond retting. 'Enzymatic' retting of flax has been researched as a technique to engineer fibers with specific properties. Dressing
1612-413: Is relatively dry with low levels of underground water , making agriculture largely reliant on the rainfall. Rainfall varies from the coastal regions, which have more dependable rain to the drier and more volatile inland regions. In the wheatbelt, both land productivity and prices tend to be determined by the level of rainfall. Wheat-growing regions in Australia are situated within the temperate zones of

1664-421: Is stable against excessive oxidation when stored for nine months at room temperature, and under warehouse conditions, for 20 months at ambient temperatures. Three phenolic glucosides — secoisolariciresinol diglucoside , p-coumaric acid glucoside, and ferulic acid glucoside—are present in commercial breads containing flax seed. After crushing the seeds to extract linseed oil, the resultant linseed meal
1716-748: The Mediterranean and the Romans used it for their sails . As the Roman Empire declined, so did flax production. But with laws designed to publicize the hygiene of linen textiles and the health of linseed oil, Charlemagne revived the crop in the eighth century CE . Eventually, Flanders became the major center of the European linen industry in the Middle Ages . In North America, colonists introduced flax, and it flourished there, but by
1768-491: The straw from the fiber. Heckling is pulling the fiber through various sizes of heckling combs or heckles. A heckle is a bed of "nails"—sharp, long-tapered, tempered, polished steel pins driven into wooden blocks at regular spacing. In September 2009, Canadian flax exports reportedly had been contaminated by a deregistered genetically modified cultivar called 'Triffid' that had food and feed safety approval in Canada and
1820-689: The 19th century, when cotton overtook flax as the most common plant for making rag-based paper . Flax is grown on the Canadian prairies for linseed oil, which is used as a drying oil in paints and varnishes and in products such as linoleum and printing inks . Linseed meal, the by-product of producing linseed oil from flax seeds, is used as livestock fodder . Flax seeds occur in brown and yellow (golden) varieties. Most types of these basic varieties have similar nutritional characteristics and equal numbers of short-chain omega-3 fatty acids . Yellow flax seeds, called solin ( trade name " Linola "), have
1872-785: The U.S. Canadian growers and the Flax Council of Canada raised concerns about the marketability of this cultivar in Europe where a zero tolerance policy exists regarding unapproved genetically modified organisms . Consequently, Triffid was deregistered in 2010 and never grown commercially in Canada or the U.S. Triffid stores were destroyed, but future exports and further tests at the University of Saskatchewan proved that Triffid persisted in at least two Canadian flax varieties, possibly affecting future crops. Canadian flax seed cultivars were reconstituted with Triffid-free seed used to plant
1924-768: The country such as areas that receive more than 300 mm (11.8 inches) of rainfall annually. The isopleth of the wheatbelt corresponds to the Goyder's line in South Australia , with Orroroo and Minnipa being on the boundary. In Western Australia , Southern Cross lies on the bounds, with other areas on the boundary being Mildura in Victoria , Cobar or Walgett to Deniliquin in New South Wales , and St George in Queensland . In addition to wheat,
1976-448: The crop steadily spread, reaching as far as Switzerland and Germany by 5,000 years ago. In China and India, domesticated flax was cultivated at least 5,000 years ago. Flax was cultivated extensively in ancient Egypt , where the temple walls had paintings of flowering flax, and mummies were embalmed using linen. Egyptian priests wore only linen, as flax was considered a symbol of purity. Phoenicians traded Egyptian linen throughout
2028-412: The early 20th century, cheap cotton and rising farm wages had caused production of flax to become concentrated in northern Russia, which came to provide 90% of the world's output. Since then, flax has lost its importance as a commercial crop , due to the easy availability of more durable fibres. Flax is grown for its seeds, which can be ground into a meal or turned into linseed oil , a product used as
2080-401: The fiber. The stems are then pulled through "hackles", which act like combs to remove the straw and some shorter fibers out of the long fiber. Several methods are used for retting flax. It can be retted in a pond, stream, field, or tank. When the retting is complete, the bundles of flax feel soft and slimy, and quite a few fibers are standing out from the stalks. When wrapped around a finger,
2132-407: The field in the spring. Two ways are used to harvest flax fiber, one involving mechanized equipment (combines), and a second method, more manual and targeting maximum fiber length. Flax for fiber production is usually harvested by a specialized flax harvester. Usually built on the same machine base as a combine, but instead of the cutting head it has a flax puller. The flax plant is turned over and

2184-402: The flax is the process of removing the straw from the fibers. Dressing consists of three steps: breaking, scutching, and heckling. The breaking breaks up the straw. Some of the straw is scraped from the fibers in the scutching process, and finally, the fiber is pulled through heckles to remove the last bits of straw. Breaking breaks up the straw into short segments. Scutching removes some of
2236-610: The flax plant. The plant species is known only as a cultivated plant and appears to have been domesticated just once from the wild species Linum bienne , called pale flax. The plants called "flax" in New Zealand are, by contrast, members of the genus Phormium . Several other species in the genus Linum are similar in appearance to L. usitatissimum , cultivated flax, including some that have similar blue flowers, and others with white, yellow, or red flowers. Some of these are perennial plants, unlike L. usitatissimum , which
2288-399: The flax straw is not harvested, typically, it is burned, since the stalks are quite tough and decompose slowly ( i.e. , not in a single season). Formed into windrows from the harvesting process, the straw often clogs up tillage and planting equipment. Flax straw that is not of sufficient quality for fiber uses can be baled to build shelters for farm animals, or sold as biofuel, or removed from
2340-410: The inner woody part springs away from the fibers. Pond retting is the fastest. It consists of placing the flax in a pool of water which will not evaporate. It generally takes place in a shallow pool which will warm up dramatically in the sun; the process may take from a few days to a few weeks. Pond-retted flax is traditionally considered of lower quality, possibly because the product can become dirty, and
2392-399: The stalk. The first step in this process is retting , which is the process of rotting away the inner stalk, leaving the outer parts intact. At this point, straw, or coarse outer stem ( cortex and epidermis ), is still remaining. To remove this, the flax is "broken", the straw is broken up into small, short bits, while the actual fiber is left unharmed. Scutching scrapes the outer straw from
2444-401: The straw (stem) from the fiber, and one for further separating the broken straw and matter from the fiber. The second part of the process brings the flax into a state for the very finest purposes, such as lace , cambric , damask , and very fine linen . This second part is performed by a refining machine. Before the flax fibers can be spun into linen, they must be separated from the rest of
2496-400: The usable flax fibers from other components requires pulling the stems through a hackle and/or beating the plants to break them. Flax processing is divided into two parts: the first part is generally done by the farmer, to bring the flax fiber into a fit state for general or common purposes. This can be performed by three machines: one for threshing out the seed, one for breaking and separating
2548-518: The use of flax as an industrial fiber. Flax seeds are 7% water, 18% protein , 29% carbohydrates , and 42% fat (table). In 100 grams (3.5 oz) as a reference amount, flax seeds provide 534 kilocalories and contain high levels (20% or more of the Daily Value , DV) of protein, dietary fiber , several B vitamins , and dietary minerals . Flax seeds are especially rich in thiamine , magnesium , and phosphorus (DVs above 90%) (table). As
2600-458: The waters used for the process. In field retting, the flax is laid out in a large field, and dew is allowed to collect on it. This process normally takes a month or more, but is generally considered to provide the highest quality flax fibers, and it produces the least pollution. Retting can also be done in a plastic trash can or any type of water-tight container of wood, concrete, earthenware, or plastic. Metal containers will not work, as an acid
