“…It has been used in traditional medicine for years and abundant literature is present explaining the health-promoting effects of flax seeds [4]. Multiple studies demonstrate the antioxidant [8], anti-inflammatory [9], analgesic [10[, antidiabetic [10], antihyperglycemic [11], anticancer [12], antifungal [13] and antibacterial [14] activity of flax seeds that proves it as a significant plant source which needs a lot more investigation in the medicinal field. Regarding the antibacterial activity, in particular, results of an in vitro study showed a promising inhibitory activity by ethanolic extract of flax seeds against B. cerues, S. aureus, P. Aeruginosa and K. pneumoniae [15].…”

Background: Flax seeds has health-potentiating medicinal benefits due to the presence of a remarkable amount of bioactive compounds. The antibacterial activity of ethanolic extract of flax seeds against Bacillus cereus, Staphylococcus aureus, Pseudomonas aeruginosa and Klebsiella pneumoniae has been documented. Therefore, the current study current aims to investigated the antibacterial activity flax seeds extract rinse against Streptococcus mutans colonies Methodology: It was a preclinical experimental study and sample size was n = 60. The participants were given an envelope for group randomization. Film of plaque from labial surface of teeth of study participants was collected on sterile strips that was transported to laboratory for culture in sterile containers. For culture S. mutant samples were inoculated in Columbia Agar. The flax seeds extract was diluted in distilled water in 1:4 (Extract: Distilled water) concentration. And participants were divided into 3 groups. (negative control, positive control, flax seed extract group). Diluted flax seed extract was given to experimental group for rinses, distilled water was given to negative control group and positive controls were given a commercially available mouth rinse. Next sample of plaque was collected after two hours to observe the effects of flax seed extract on bacterial colonies. Results: The growth of colonies was calculated on growth media plates in samples prior to rinsing and samples that were taken after the rinsing. The pre and post samples showed significant (p-value <0.05) decrease in number of colonies in positive control group (conventional rinse) and flax seed extract group. Conclusion: Flax seeds extract mouth rinse reduced the number of colonies equally as that of commercially available mouth rinse.

“…If we calculate the fiber based on the whole flaxseed mass, we would obtain 5.73%. In literature, Roulard et al (2016) obtained 3.31% fiber-based on whole flaxseed mass, Kaur et al (2018) reached from 5.56 to 6.54%, Basiri et al (2018) obtained 3.10%, Safdar et al (2019) obtained 7.83% and, finally, Safdar et al (2020) reached from 2.82 to 8.92%.…”

PurposeThe mucilage of the Linum usitatissimum L. seed (Linseed) is one of the natural mucilages that presents a great potential to provide a food hydrocolloid with potential applications in both food and pharmaceutical industries. To increase the yield and quality of linseed oil during its production process, it is necessary to previously extract its polysaccharides. Because of this, flax mucilage production can be made viable as a byproduct of oil extraction process, which is already a product of high commercial value consolidated in the market. Thus, the purpose of this work is to optimize the mucilage extraction process of L. usitatissimum L. using the normal-boundary intersection (NBI) multiobjective optimization method.Design/methodology/approachCurrently, the variables of the process of polysaccharide extraction from different sources are optimized using the response surface methodology. However, when the optimal points of the responses are conflicting it is necessary to study the best conditions to achieve a balance between these conflicting objectives (trade-offs) and to explore the available options it is necessary to formulate an optimization problem with multiple objectives. The multiobjective optimization method used in this work was the NBI developed to find uniformly distributed and continuous Pareto optimal solutions for a nonlinear multiobjective problem.FindingsThe optimum extraction point to obtain the maximum fiber concentration in the extracted material was pH 3.81, temperature of 46°C, time of 13.46 h. The maximum extraction yield of flaxseed was pH 6.45, temperature of 65°C, time of 14.41 h. This result confirms the trade-off relationship between the objectives. NBI approach was able to find uniformly distributed Pareto optimal solutions, which allows to analyze the behavior of the trade-off relationship. Thus, the decision-maker can set extraction conditions to achieve desired characteristics in mucilage.Originality/valueThe novelty of this paper is to confirm the existence of a trade-off relationship between the productivity parameter (yield) and the quality parameter (fiber concentration in the extracted material) during the flaxseed mucilage extraction process. The NBI approach was able to find uniformly distributed Pareto optimal solutions, which allows us to analyze the behavior of the trade-off relationship. This allows the decision-making to the extraction conditions according to the desired characteristics of the final product, thus being able to direct the extraction for the best applicability of the mucilage.

“…Under a pH of 6–9, the maximum gel strength could be obtained, the addition of sodium ions reduced the gel’s strength, and the low concentration of calcium ions could increase the gel’s strength. Safdar et al [ 6 ] compared four FG extraction methods. The FG extracted using the four methods showed concentration dependence in the antioxidant test, among which the ultrasound-assisted FG exhibited a higher radical removal ability of ABTS, DPPH, reduction, and β-carotene.…”

In this study, flaxseed gum (FG) was extracted using hot water extraction and ultrasonic-assisted extraction. The yield, molecular weight distribution, monosaccharide composition, structure, and rheological properties of FG were analyzed. The FG yield (9.18) achieved using ultrasound-assisted extraction (this sample was labeled as UAE) was higher than the yield (7.16) achieved with hot water extraction (this sample was labeled as HWE). The polydispersity, monosaccharide composition, and characteristic absorption peaks of the UAE were similar to that of the HWE. However, the UAE had a lower molecular weight and looser structure than the HWE. Moreover, zeta potential measurements indicated that the UAE exhibited better stability. An analysis of the rheological properties showed that the viscosity of the UAE was lower. Thus, the UAE had an effectively better yield of FG, preliminarily modified structure, and rheological properties, and provided a theoretical basis for its application in food processing.
