“…The two major grown cultivars are oil flax (producing more seeds) and fibre flax (containing more protein in its seeds, generally taller and with less branches). The latter is cultivated for the fibre from its stem, while both cultivars' seed can be used for oil production [49][50][51].…”

“…Tocopherol and tocotrienol (vitamin E derivatives) and sterols are also present in the lipid fraction [54]. Flaxseed is an important source of bioactive molecules, having diverse positive health effects (protection against diabetes [54], cardiovascular diseases, osteoporosis [51], anti-inflammatory activity and laxative activity [58]) as well as phenolic compounds (blocking agents for cancers induced by aromatic carcinogens [55]), explaining the increased interest in the crop [47].…”

Bio-Refinery of Oilseeds: Oil Extraction, Secondary Metabolites Separation towards Protein Meal Valorisation—A Review

Edible oil extraction is a large and well-developed sector based on solvent assisted extraction using volatile organic compounds such as hexane. The extraction of oil from oilseeds generates large volumes of oilseed by-products rich in proteins, fibres, minerals and secondary metabolites that can be valued. This work reviews the current status and the bio-macro-composition of oilseeds, namely soybean, rapeseed, sunflower and flaxseed, and the refining process, comprising the extraction of oil, the valorisation and separation of valuable secondary metabolites such as phenolic compounds, and the removal of anti-nutritional factors such as glucosinolates, while retaining the protein in the oilseed meal. It also provides an overview of alternative solvents and some of the unconventional processes used as a replacement to the conventional extraction of edible oil, as well as the solvents used for the extraction of secondary metabolites and anti-nutritional factors. These biologically active compounds, including oils, are primordial raw materials for several industries such as food, pharmaceutical or cosmetics.

“…Flax seeds also have a high oil content with 96% of TAGs (triacylglycerols) mainly localized in the embryo. The major fatty acid found in the flax seed oil is linolenic acid (ω-3, LIN, C18:3, 50-62%) and palmitic acid (PAL, C16:0, 4-6%), steric acid (STE, C18:0, 2-4.4%), oleic acid (OLE, C18:1, 10-24.2%), linoleic acid (ω-6, LIO, C18:2, 12-18%) are also present [25][26][27]. Oilseed species, such as Arabidopsis and flax, accumulate oil from early-middle to late stages of seed development [5,28].…”

Flax (Linum usitatissimum L.) seed oil, which accumulates in the embryo, and mucilage, which is synthesized in the seed coat, are of great economic importance for food, pharmaceutical as well as chemical industries. Theories on the link between oil and mucilage production in seeds consist in the spatio-temporal competition of both compounds for photosynthates during the very early stages of seed development. In this study, we demonstrate a positive relationship between seed oil production and seed coat mucilage extrusion in the agronomic model, flax. Three recombinant inbred lines were selected for low, medium and high mucilage and seed oil contents. Metabolite and transcript profiling (1H NMR and DNA oligo-microarrays) was performed on the seeds during seed development. These analyses showed main changes in the seed coat transcriptome during the mid-phase of seed development (25 Days Post-Anthesis), once the mucilage biosynthesis and modification processes are thought to be finished. These transcriptome changes comprised genes that are putatively involved in mucilage chemical modification and oil synthesis, as well as gibberellic acid (GA) metabolism. The results of this integrative biology approach suggest that transcriptional regulations of seed oil and fatty acid (FA) metabolism could occur in the seed coat during the mid-stage of seed development, once the seed coat carbon supplies have been used for mucilage biosynthesis and mechanochemical properties of the mucilage secretory cells.

La presente investigación tuvo como objetivo evaluar el efecto del pH y NaCl sobre el poder de absorción de agua, capacidad gelificante, emulsificante y espumante de harina de semillas residuales de linaza (Linum usitatissimum L.). La harina residual (sin mucílago) se obtuvo sometiendo a ebullición las semillas en agua destilada para su posterior filtración y secado (40 °C x 48 horas) y conversión en harina (harina tipo A). También se obtuvo harina de semillas de linaza entera (sin extraer el mucílago) a la cual se le denominó harina tipo B. Las propiedades tecnofuncionales fueron determinadas a pH de 3, 5, 7 y 9 así como en concentraciones de NaCl de 0.1, 0.25 y 0.5 M. La mayor capacidad de absorción de agua en la harina tipo A y B fue de 2.81 y 2.38 g H2O/g sólido respectivamente a pH 5. La absorción de aceite en las harinas tipo A y B fue de 1.87 y 1.26 g aceite/g sólido. La mayor emulsión en la harina tipo A (45.8%) se obtuvo a pH 9, en tanto que para la harina tipo B (57.97%) a pH 3. En la harina tipo A la gelificación fue débil a partir del 20% p/p, en tanto que en la harina tipo B fue débil a partir del 10% y fuerte a partir del 16% p/p. La capacidad espumante de la harina tipo A fue de 10.7% y de 4.07% en la harina tipo B, ambos a pH 7.
