“…Non-digestible polysaccharides such as galacto-oligosaccharides, fructooligo-saccharides and cyclodextrins are known to be prebiotic substances which selectively stimulate the growth and/or activity of the gastrointestinal micro-flora (Gibson, Probert, Loo, Rastall, & Roberfroid, 2004). The heterogenic polysaccharide, flaxseed mucilage/gum, is the soluble fiber components that constitute about 6 to 8% of the whole seed (on a dry weight basis; Cui & Mazza, 1996). Fodje, Chang, and Leterme (2009) demonstrated that high amounts of acetate and propionate (short-chain fatty acids) resulted when flaxseed was fermented in vitro.…”

This study investigated the capability and efficiency of flaxseed soluble dietary fibre /mucilage to enhance bacterial survival and growth in kefir as well as the antioxidant activity of the mucilage. Crude flaxseed mucilage was extracted using a microwave method, followed by enzymatic and dialysis treatments to obtain pure mucilage. The antioxidant activities of the pure and crude mucilage were measured using different assays. Microbial analyses, pH and total titratable acidity (TTA) were measured in kefir samples, supplemented with probiotic bacteria (Lactobacillus acidophilus and Bifidobacterium lactis) and pure or crude flaxseed mucilage during 28 cold storage periodat 4 ºC. The results showed that for all kefir samples, the total bacteria counts were above7.9 log cfu/mL at the end of cold storage period. However, kefir samples supplemented with pure flaxseed mucilage enhanced significantly (P < 0.05) higher viability of bacteria (9.5 log cfu/mL) and acidity (0.78% TTA). An overall pH decline of 0.2 was observed during cold storage period. The total phenolic content (TPC) in crude mucilage was significantly (P < 0.05) higher than pure mucilage (10.5 ± 0.2 and 5.7 ± 0.1 mg Gallic acid equivalent /g flaxseed, respectively). The mucilage from crude flaxseed exhibited strong antioxidant activity; Oxygen Radical Absorbance Capacity (ORAC) value of 51.2 ± 3.3 μmol Trolox equivalent /g, 53.7 ± 2.8% discoloration for 2,2-diphenyl-1-picrylhydrazyl (DPPH), and 68.3 ± 9.2% β-Carotene bleaching which was well in agreement with high TPC. This study demonstrated that flaxseed mucilage acts as a good source of prebiotic, enhancing lactic acid bacteria growth in kefir model in addition of their high antioxidant beneficiary.

“…This was mainly caused by the faster disruption of polymer network due to external forces, which exceeded the formation rate of new entanglements within the polymer. Cui and Mazza [26] showed similar shear-thinning flow behavior of AX extracted from flaxseed flour in aqueous solutions above 1% (w/w).…”

Background: Rye arabinoxylans (AXs) might be used as baking improvers for gluten-free (GF) bread. However, their extraction process still needs to be improved. Objective and methods:The aim of this study was to simplify AX extraction of rye bran by varying temperature and pH and evaluate its chemical and rheological properties for application in GF bread. Results and conclusion:The results demonstrated that higher amounts of AX and impurities were extracted with the increasing pH and temperature. AX yield reached values up to 3.3 g AX/100 g bran. Highest ferulic acid (FA) content (117.27 ± 1.46 mg/100 g) was achieved at the mildest extraction conditions (30 °C and 0.17 M NaOH). A/X ratio of isolates ranged between 0.53 and 0.57 and the gluten content between 81.30 and 216.78 ppm. Rheological measurements revealed typical pseudoplastic behavior of isolates. AX extracted at 30 °C and 0.17 M NaOH showed a slightly higher initial viscosity in comparison with the other isolates but was still inferior to carboxylmethylcellulose (CMC) and hydroxypropyl methylcellulose (HPMC).

“…A semente de linhaça é composta por cerca de 35% de fibra, das quais 2/3 é fibra insolúvel, constituída de celulose, hemicelulose e lignina e 1/3 de fibra solúvel, a qual grande parte (cerca de 8% do seu peso) se encontra na forma de mucilagem ou goma (TARPILA; WENNBERG; TARPILA, 2005), cuja sua composição consiste em xilose (19-38%), ácido galacturônico (21-36%), rhamnose+fucose (11-16%), galactose (12-16%), arabinose (8-13%) e pequena quantidade de glicose (4-6%) (WANNERBERGER; NYLANDER; NYMAN, 1991;OOMAH et al, 1995;MAZZA, 1996). O rendimento de extração da mucilagem é dependente do regime de extração, podendo variar de 3,5-9,4% (MAZZA; BILIADERIS, 1989;FEDENIUK;BILIADERIS, 1994;OOMAH et al, 1995).…”

This study was conducted out to evaluate the effect of partial replacement of animal protein (PBOA) for crude protein demucilaged linseed meal (PBFLD) and in nature (PBFL) ± 1.85 g) were reared in water recirculation system and fed to apparent satiation three times a day. At the end experimental parameters were evaluated for growth, carcass, chemical composition in whole fish and digestive enzymes. The fish fed control diet had best levels of feed conversion (p <0.05), however the remainder of the growth parameters were not altered by the inclusion of FL and FLD. There were no significant differences in hepatosomatic relation (RHS) and digestivosomatic relation (RDS). Diet 35%FLD had a lower intestinal quotient (QI), moisture content and higher carcass fat, total fat deposited and activity of the enzyme trypsin. It can be concluded that the FLD and FL can be used as a substitute of meat meal to the diets in juvenile jundia feed as an alternative source and cost.
