Oilseed cakes are produced as a by-product of oil pressing and mostly used feed. Their use for human consumption is due to the functional properties benefits health. Herein, oilseed cake flours eight species (flax, hemp, milk thistle, poppy, pumpkin, rapeseed, safflower, sunflower) were sieved into fractions above (A250) below (B250) 250 µm. The chemical composition, SDS-PAGE profiles, colour, antioxidant activities these evaluated. B250 evaluated being protein ash rich, reaching crude...

It is hypothesized that oligosaccharides are another potential source of immunological cross-reaction between different plant allergens. Patatin the most abundant glycoprotein in potato and has been described to have an oligosaccharide composition Man3(Xyl)GlcNAc2(Fuc). In this work, N-glycosylation profiles patatin proteins isolated from tubers species were investigated compared. Oligosaccharides released by enzymatic digestion with PNAGase A analyzed primarily matrix-assisted laser...

Faba beans (Vicia faba L.) are a high-protein legume crop that can be widely cultivated in most climates Europe. The amino acid composition of the bean protein is also beneficial for monogastric animals since it contains great deal lysine, an deficient cereals. Two genotypes were at three sowing densities (45, 60 and 75 seeds per m2) during growing seasons (years 2013–2015). aim research was to assess accumulation nutrients (N, P, K, Ca Mg) two straw under different densities. A field...

Onion skin is a waste produced in thousands of tons annually the European Union. It rich natural source flavonoids and its water extracts (as an environmentally friendly solvent) could be used as antioxidant material for meat products. Therefore, properties onion (OSWEs) were tested on cooked pork patties. Pork patties divided into five treatments: control (no antioxidant), 10 20% (w/w) yellow OSWE, red OSWE. Antioxidant activity, total polyphenols, thiobarbituric acid reactive substances...

The biological effect of oxygen-reactive species controlled by antioxidant mechanisms are exerted on the basis enzymes and substrates. In this study, activities enzymes-superoxide dismutase (SOD) glutathione peroxidase (GPx)-were determined in erythrocytes patients regular haemodialysis treatment. SOD activity was significantly lower (1,810.38 +/- 609.85 vs. 2,347.13 502.51 U/g haemoglobin, p < 0.05, or 70.71 11.50 100.13 24.28 mU/10(6) erythrocytes, 0.0001), as GPx (18.80 4.22 23.26 3.61...

The research is focused on the quantitative evaluation of flaxseed (Linum usitatissimum L.) proteome at level seed cake (SC), fine flour—sieved a fraction below 250 µm (FF)—and protein concentrate (PC). was performed three oilseed flax cultivars (Agriol, Raciol, and Libra) with different levels α-linolenic acid content using LC-MS/MS (shotgun proteomics) analysis, which finalized by database searching NCBI for Linum related species. A total 2560 groups (PGs) were identified, their relative...

Secondary amyloidosis is a complication typical for patients on long-term hemodialysis. The first clinical signs are usually shoulder joint pain and carpal tunnel syndrome (CTS). We have questioned 74 who were regular hemodialysis (HD) treatment divided them into 3 groups according to the length of HD. Group 1—on HD 1–4 years: There 35 in this group, 15 (i.e., 43%) had andlor CTS. None these symptoms that would require surgical treatment. II—on HDfor 5–9 22 68%) and/or Three from group...

As a source of nutritionally important components, hemp seeds are often dehulled for consumption and food applications by removing the hard hulls, which increases their nutritional value. The hulls thus become waste, although they may contain valuable protein items, about there is lack information. present work therefore aimed at evaluating proteome (Cannabis sativa L.) whole-seed, seed, hull levels. evaluation was performed on two cultivars, Santhica 27 Uso-31, using LC-MS/MS analysis. In...

The contribution deals with thermal stability and re-solubility of potato tuber proteins isolated by ethanol precipitation from industrial fruit juice. protein isolate was exposed to the temperatures ranging 25°C 70°C. Patatin, a high nutritious value, detected SDS-PAGE in region 39-43 kDa. Patatin evaluated as sensitive - above 30°C caused its strong insolubility. Potato protease inhibitors were 4.3 24 Thermal (region 25 14 kDa) higher, although 45°C denaturation insolubility most...

The influence of pumpkin seed roasting conditions (110-140 °C) and screw-pressing on the formation previously undescribed Δ7-phytosterol oxidation products tocopherylquinone adducts with nucleophilic phosphatidylethanolamine species was investigated. process paste at a temperature above 120 °C for 30 min considerably enhanced Δ7-oxysterols. Targeted analysis [electron impact mass spectrometry (MS), 1D-nuclear magnetic resonance] led to identification five novel markers roasting, among which...

The utilization of plant by-products as functional food ingredients has received increasing attention in the last decade. One such by-product generated during milk thistle oil pressing is oilseed cakes, which could be used a novel ingredient. Therefore, study aimed at investigating effects addition cake (MTOC) flour fractions obtained via dry sieving, differing particle size (unsieved; coarse: >710 µm; medium: 315−710 and fine: <315 µm), on quality gluten-free bread stability silymarin...
