The objective of the present work was to determine nutrient and polyphenolic composition dried strawberry press cake (SPC), as well that its seedless fraction, termed exhausted flesh (ESF). study materials were obtained over three consecutive years from an industrial facility manufacturing concentrated fruit juices. On average, SPC consists 40 % seeds, 3.5 sand, about 55 ESF. In dry matter ESF, mean content fat is 9.8 %, protein 17.3 20.4 total polyphenols 3,449 5,410 mg/100 g, respectively....
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...
The putative health benefits of raspberries and raspberry-based products are potentially attributable to the presence polyphenolic compounds, such as ellagitannins, anthocyanins, flavanols, flavonols. Their content in raspberry processing into juice may be affected by fruit cultivar, technological process parameters, properties polyphenolics themselves. objective study was investigate composition quantity above their (that is, press cake, including its seed seedless fractions). also examined...
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 strong acid hydrolysis analysis of galloyl-O-digalloyl-type ellagitannins (ETs), lambertianin C (LC) and sanguiin H-6, dehydrodigalloyl-type ET, agrimoniin (AM), was performed. A quantitative qualitative the degradation products individual ETs conducted using high-performance liquid chromatography–diode array detecto–electrospray ionization interface–mass spectrometry (HPLC–DAD–ESI–MS). data indicate that undergo multidirectional changes in a strongly acidic environment, where process...
