Unprocessed pomace containing 61% of dietary fiber (DF) and 0.23% polyphenols (PP) ethanol- or ethanol/acetone-extracted pomaces 66% DF 0.10% PP 67% 0.01% PP, respectively, were subjected to a 4 week study in rats. The aim the was assessing advantages supplementation with above pomaces. To measure animal response treatments, parameters describing cecal fermentation lipoprotein profile assessed. use 5% unprocessed caused an increase short-chain fatty acid (SCFA) production decrease blood...
Strawberry and raspberry seeds were chemically analyzed added as dietary ingredients to investigate the physiological response of rats. In both cases main component was fiber polyphenols ellagitannins (ET). The strawberry ET mainly constituted by monomers a dimer, agrimoniin, whereas sanguiin-H-6, trimer, lambertianin-C. lower content less polymerized structure resulted in higher cecal metabolites concentration (mainly nasutin urolithin-A) comparison rats fed diet containing seeds. Dietary...
According to many scientific studies, ellagitannins are beneficial for human health. One of the sources these compounds is strawberry press-cake. This material can be used production dietary fiber or ellagitannin preparations. The health safety press cake and preparations that rich in obtained from it depend on pesticide residue levels, mainly fungicides, which protection. aim work was a risk assessment measured by %ADI (acceptable daily intake) MOE (margin exposure) associated with presence...
The administration of fructooligosaccharides (FOS) beneficially modulates gastrointestinal functions and may enhance the metabolism polyphenols. However, different polyphenolic components in diet have influences on activities digestive enzymes microbiota tract. Therefore, a 4-week study forty-eight male Wistar rats was conducted to investigate physiological response rat cecal environment diets without with FOS that contained two strawberry extracts, specifically EP (polyphenolic profile 60,...
The aim of this study was to determine the efficacy different dietary fruit pomaces in reducing lipid oxidation meat turkeys fed diets with a high content n-3 polyunsaturated fatty acids (PUFAs). Over period 4 weeks before slaughter, were addition 5% dried apple, blackcurrant, strawberry and seedless (groups AP, BP, SP SSP, respectively) 2.5% linseed oil. Pomaces differed (from 5.5 AP 43.1 mg/g SSP) composition polyphenols Proanthocyanidins main polyphenolic fraction all pomaces, contained...
We investigated the effects of dietary supplementation with strawberry extracts rich in ETs and fructo-oligosaccharides (FOS) on intestinal microbiota formation bacterial metabolites distal intestine, as well absorption ET antioxidant status rats.Rats were allocated into six groups eight animals each fed for 4 weeks a control diet (group C), supplemented FOS C + FOS) or modifications these diets, which monomeric dimeric ET-rich extract was added (groups ME DE FOS, respectively).The addition,...
Yellow onion waste from industrial peeling was used to obtain three pure preparations: protocatechuic acid (PA), quercetin diglycosides (QD) and monoglycosides (QM).
The objective of this study was to establish the composition polyphenolic preparations obtained from industrial strawberry pomace with two methods extraction: water and water-alcoholic one then analyse their effects in gastrointestinal tract depending on dietary fibre-cellulose or fructooligosaccharides (FOS).Freeze-dried extract (PTW), containing 5.1% ellagic acid, 0.2% proanthocyanidins, soluble carbohydrates as a major part, water-alcohol (PTE), 17.1% acid 10.9% were administered,...
The objective of the work was to elucidate chemical composition fractions oil extracts obtained during supercritical extraction on a semi-industrial scale from strawberry (Fragaria x ananassa Duch.), chokeberry [Aronia melanocarpa (Michx.)], and raspberry (Rubus idaeus L.) seeds industrial press cake. differed in terms their content bioactive components: carotenoids, tocopherols, chlorophylls, fatty acids. Raspberry seed richest source tocopherols (620.1–2166.7 mg kg−1) α-linolenic acid...
Blackberry fiber (BF), extracted blackberry (EBF), defatted seeds (DBS), and polyphenols (BP) were added to the diets of rats. A control diet, (BF, EBF, DBS) with 6% addition instead cellulose, a polyphenol diet 1% administered for 4 weeks. BF DBS contained (3.6%); EBF did not. was free fat. Ellagitannins main phenolics, mostly dimers (sanguiin H-6 isomers) monomers (pedunculagin, casuarictin isomer, sanguiin H-2 isomer). Trimers (lambertianin C tetramers D) in minority. increased production...
The present paper describes a comparative study of the metabolism (1) ellagic acid, (2) monomeric ellagitannins (a mixture α- and β-bis-hexahydroxydiphenoyl-d-glucose), (3) dimeric (mainly agrimoniin with both glucose residues being esterified hexahydroxydiphenoyl) in rats fed polyphenol-rich diets. Their metabolites were identified quantified selected parts gastrointestinal tract, i.e., stomach, small intestine, cecum, on second, fourth, seventh days experiment, as well rats' feces, blood...
Fruit pomaces are by-products rich in polyphenol compounds and dietary fiber. They seem to play an important role regulating the gut microbiota, morphology physiology. The aim of this study was assess whether apple (A), blackurrant (B) or strawberry (S) could be suitable ingredients broiler diets their effect on health. A total 480 male broilers were randomly allotted 8 treatments with lower (3%-L) higher (6%-H) fiber content: two control groups (CL/CH), (AL/AH), B (BL/BH), S (SL/SH). Diet...
Apple pomace with seeds had no adverse effects in a 4-week feeding study rats and retained its functionality.
The present study compares the effects of two dietary strawberry extracts rich in monomeric (ME) or dimeric (DE) ellagitannins (ETs) on gastrointestinal, blood and tissue biomarkers Wistar rats fed high-fructose diets. Both beneficially affect antioxidant status lipid profile liver serum. ME extract shows a greater ability to inhibit peroxidation kidneys, more effectively decreases serum triglycerides, exerts anti-inflammatory than DE extract. significantly reduces activity microbial enzymes...
Due to the demonstrated intestinal microbial transformation of strawberry ellagitannins (ET) into bioactive metabolites, in current study on rats, we hypothesised that dietary addition a ET-rich extract (S-ET) high-fat diet (HFD) would attenuate disturbances redox and lipid status as well inflammatory response. We randomly distributed 48 Wistar rats six groups used two-way analysis variance (ANOVA) assess effects two main factors—diet type (standard high-fat) ET dosage (without, low, 3×...
