This study aimed to produce healthy mayonnaise with a protective effect against cardiovascular diseases, containing omega-3 fatty acids (FA), using flaxseed oil (FXO), which includes a high percentage of alpha-linolenic acid (ALA, C18:3n-3). The mayonnaise was prepared by replacing soybean oil with FXO at 20, 30, and 40% levels. The effect on the organoleptic, physical, and chemical quality was studied compared to a control, prepared only with soybean oil (70%). The oxidative and microbial stability during 12 weeks of storage at 25 and 7 °C was also evaluated. The results showed that the use of FXO in mayonnaise (20, 30, and 40%) led to an increase in TUFA (from 79.37 (control) to 82.48, 85.49, and 87.66%, respectively), particularly in PUFAn-3, due to the rise of ALA (from 6.5 to 18.38, 24.02 and 37.87%, respectively) and a decrease in TSFA (from 20.63 to 17.52, 14.51 and 12.34%, respectively). The panelists did not perceive significant differences in the sensory characteristics of the "new" mayonnaise. A decrease in the oxidation rates of the "new" mayonnaise during the storage period was observed. A significant effect on microbial growth was not reported, although the permissible limits were not exceeded after 12 weeks of storage, even at 25 °C.

Non-communicable diseases (NCD) are associated with inflammation and oxidative stress which is further associated with omega-6 (ω6) and omega-3 (ω3) fatty acid (FA) imbalance favoring ω6 FA. By improving ω3 FA consumption, this imbalance can be altered to control NCD. Previously we have reported blends of flaxseed oil (FSO, ω3 FA) with palm olein (PO) or coconut oil (CO) were thermo-oxidatively stable with good storage stability and could improve ω6:ω3 ratio in cell lines.

The effects of three dietary oils (rapeseed oil, camellia oil, linseed oil) with different fatty acid compositions on the growth performance, digestion and gut microbiota of rats after 8 weeks of feeding were studied. The serum metabolic index and liver histomorphology of rats were measured using an automatic biochemical analyzer and light microscope. Furthermore, 16S rDNA amplicon sequencing technology was used to analyze the gut microbiota.

The aim of this study was to compare the functional properties of linseed oil powders made of three types of wall material (OSA starch + maltodextrin, OSA starch + nutriose, and OSA starch + inulin) and two types of emulsion phases (micro- and nanoemulsion). For these independent variables, the properties of the prepared emulsions (flow curves and viscosity) and the resulting powders (encapsulation efficiency, particle size distribution, water activity, bulk and tapped density, Carr's index, color parameters, and thermal stability) were determined. The results showed that emulsion viscosity and most powder properties were affected by the emulsion type.

This study aimed to evaluate the oxidative stability and surface properties of cold-pressed vegetable oils using the Langmuir monolayer technique. Six oils-milk thistle, evening primrose, flaxseed, camelina sativa, black cumin, and pumpkin seed-were analyzed to investigate their molecular organization and behavior at the air/water interface, particularly after undergoing oxidation. The results showed that oils rich in polyunsaturated fatty acids (PUFAs), such as flaxseed and evening primrose oils, formed monolayers with larger molecular areas and lower stability, which led to faster oxidative degradation, especially under thermal conditions.

The paper presents the results of research on the rheological properties and stability of oil-in-water emulsions containing cellulose derivatives: methylcellulose, hydroxyethylcellulose, and hydroxypropylmethylcellulose. The continuous phase of the emulsion was a 70% ethanol (EtOH) solution by volume. The dispersed phase consisted of mineral, linseed, and canola oils (20% by volume).
