Fatty Acid Composition of Flax Sprouts

Abstract

The oil and fatty acid profile of flax (Linum usitatissimum) sprouts and seed were compared to determine nutrition potential of sprouts. Equal quantities of seed from three flax cultivars (Rahab-94, Pembina and Linott) were sprouted twice in three replications and were analysed for oil and fatty acid contents during summer 2011. Three flax cultivars were observed with high oil content on dry weight basis in sprouts (15.9%) and seeds (33.99%). Significant variations (P<0.0001) between seed and sprout values for contents of unsaturated, polyunsaturated (UFA, PUFA) and saturated (SFA) fatty acids (P=0.0002) and non-significant (P>0.05) variation among three cultivars was observed. The percentage of PUFAs in cultivars Pembina and Linott was 68.7 and in Rahab-94 was 67.7. The percentage of linoleic acid (C18:2) was significantly high in sprouts (19.51%) compared to seed (17.7%). The percentage of linolenic acid (18:3) was high in seed (52.8%) compared to sprouts (48.8%). The ratio of PUFA/SFA in sprouts was high in Pembina (6.97%) and Linott (6.82%) compared to Rahab-94 (6.38%). The fatty acid profile was similar in all the three cultivars with significant (P<0.0001) reduction (<1%) in PUFA/SFA ratio of sprouts compared to seed (7.4%). Flax sprouts are equally potential to seed for viable natural resources of essential fatty acids (18:2 and 18:3).

Effect of Sprouting on Chemical, Fatty Acid Composition, Antioxidants and Antinutrients of Flaxseeds

“…Using SPSS version 16.0 of the program, statistical analyses were performed. There was significant reduction in oil content of the sprouted flaxseeds when compared to the flaxseeds at zero time (29.60%) (Table 1), this trend is in agreement with that reported by Herchi [28], Kajla [30] and Narina [32]. The oil is the main source of energy during sprouting [33].…”

“…On the other side, C 18:2 , C 18:1 and C 20:0 increased during sprouting. These results agreed with Wanasundara [42], Narina [32] and Kaur [31]. Fatty acid composition of flaxseed oil extracted from flax sprouts agreed with Codex Alimentarius Commission (1999) Standard.…”

“…By observing in during sprouting, C16:0 was increased from 7.80 to 7.91% on the first day of germination and then decreased and increased, even C16:1 had the same pattern. Narina [32] suggested that C16:0 had decreased in flax sprouts. There was no significance difference in the first 2 days of sprouting and there was a significance difference in the 3rd and 4th day of sprouting.…”

Antimicrobial activities and mineral profile of selected wild plant Linum usitatissimum in Khyber Pakhtunkhwa, Pakistan

“…The current results find supportive evidence from the study of Khan et al (2010) who observed appreciable amount of calcium, magnesium, potassium, sodium, chlorine, phosphorus, copper, iron, manganese and zinc in different varieties of the said plant. These findings are at par with the results of (Narina et al,2013) Singh et al (2011) investigated the elemental composition of the said plants which are in agreement with present research data. These elements exhibit paramount in various physiological functions of the body.…”

Seed Protein and Starch Qualities of Drought Tolerant Pigeonpea and Native Tepary Beans

“…Pigeonpea seed has 36.5% protein (Pathak et al, 1993) with excellent water retention (250.3 ml/100g), fat absorption (130 ml/100g), emulsification (120%) and foaming (130%) capacities (Eltayeb et al, 2012). These two crops gaining pride for cultivation in southeastern USA (Pathak et al, 1993, Bhardwaj et al, 2002 due to their adaptability, and production capabilities and were potential alternative crop resources (Bhardwaj et al, 1999) for tobacco farmers and drought prone areas of USA (Narina et al, 2013) and as forage crops for animal consumption (Bhardwaj, 2013). Further, these legumes were also potential for industrial use in production of biodiesel, forage, biodegradable substances like plastics, oils, gums, and medicines besides bread, chips, tortillas, yogurt, and flavor (Graham & Vance, 2003).…”
