Modifications of nutritional properties (amino acids, available lysine, protein digestibility, fatty fiber, inositol phosphate (IPs), free and bound phenolics, antioxidant properties) whole rice ingredients processed by soaking, germination, and/or extrusion cooking were evaluated. Soaking germination reduced proteins lixiviation hydrolysis, respectively. Lysine was the limiting amino acid. Polyunsaturated acids increased after germination. Protein digestibility 100% for germinated rice,...
Summary The effect of different barley germination conditions on generation neuroprotective compounds was studied. Malts were obtained by at 20 °C for 35 h (M1), 72 (M2), 25 (M3) and (M4). M4 showed higher phenylalanine ammonia lyase (PAL) activity total phenolic acid content than the others. Moreover, a direct relationship (r2: 0.9802) between protein hydrolysis degree malt protease obtained. Regarding properties, all malts inhibited acetylcholinesterase, tyrosinase prolyl oligopeptidase...
Phytophthora is a long-established, well known and globally important genus of plant pathogens. Phylogenetic evidence has shown that the biologically distinct, obligate biotrophic downy mildews evolved from at least twice. Since, cladistically, this renders ‘paraphyletic’, it been proposed evolutionary clades be split into multiple genera (Runge et al. 2011; Crous 2021; Thines 2023; 2024). In letter, we review arguments for retention generic name with broad circumscription made by Brasier...
A combination of soaking and extrusion processes whole rice grain was studied. The effects temperature (35–55 °C) time (24–48 h) treatment on phytic acid (PA), protein ashes losses using a factorial design were evaluated. Taking into account ash, PA losses, soaked 24 h at 45 °C extruded Brabender single screw extruder. Effects (160–190 moisture content (14–19 g/100 g) product characteristics evaluated surface response methodology. Values corresponding to the different responses were:...
The aim of this study was to evaluate the influence diets with different types fibres on Ca bioavailability and metabolic parameters in growing Wistar rats. Twenty four male rats were fed 3 diets: control (C), polydextrose (PD), extruded whole maize (M) during a 60 day period. Apparent absorption percentage (%Ca Abs), total skeleton bone mineral content (t BMC), density BMD), femur (F), spine (S) tibia (T) BMD, cecum weight, pH evaluated. Malondialdehyde (MDA) lipid (TG cholesterol) contents...
Abstract In this work, two analytical methods based on liquid chromatography coupled to electrospray time‐of‐flight mass spectrometry (LC/ESI‐TOFMS) and tandem (LC/ESI‐MS/MS) are described for the identification, confirmation quantitation of three insecticides non‐authorized in European Union (nitenpyram, isocarbophos isofenphos‐methyl) but detected recent monitoring programmes pepper samples. The proposed methodologies involved a sample extraction procedure using liquid‐liquid partition...
The influence of diets with whole rice processed ingredients on cecum health, calcium absorption and bone parameters was studied using an animal model.
Whole rice (WR) products with low phytic acid (PA) content and enhanced bio-functional components were obtained by the combination of germination extrusion processes. Germination conditions (24 h - 35 °C), a previous soaking process 20 chosen according to remnant PA rate. Specific mechanical energy consumption, expansion, sensorial hardness, specific volume, solubility, water absorption, free phenolic (FPC) antioxidant capacity evaluated. Results indicated that 175 °C 14 g 100 g(-1) moisture...
The influence of whole grain (WG) rice based diets on the lipid profile and antioxidant status was evaluated.
Abstract The aim of this study is to optimize starch isolation from different sorghum cultivars and characterize the fourteen red white hybrids. Methods involving sulfite maceration and/or protein hydrolysis are assayed. Recovery yield, residual protein, total damage, whiteness index (WI), water absorption, solubility, swelling power isolated starches compared in order select appropriate method. Results indicate that recoveries between 44–76%. Isolated present 0.58–2.4 g 100 −1 proteins,...
Abstract Sorghum flour was heat treated for producing an instant dispersion ingredient. The precooked sorghum added with ACE‐I and DPP‐IV inhibitory peptides (3.0 g peptide 100 −1 ). product reconstituted in water, bioaccessibility evaluated by equilibrium dialysis method after simulated gastrointestinal digestion. Total dialysability of higher than those obtained (315.9 ± 14.8 vs. 45.2 5.6 µmol, respectively) ( P < 0.05). DPP‐IV‐IC 50 values the bioaccessible from bioactive were lower...
This work aimed to evaluate the chemical composition, bioactive compounds (phenolics and γ-aminobutyric acid, GABA), antioxidant properties of different barley varieties (Overture, Charles, Sinfonía, Montoya, Andreia) their malts weigh up them as potential ingredients for producing new bio-functional foods. For this, five barleys obtained from were studied. Regarding total starch was main component (≈62%) followed by dietary fiber (≈22.6%) proteins (≈9.5%). Potassium phosphorus most abundant...
Extruded refined sorghum flours have enough polyphenols and fermentable fibre to enhance colonic mucosa integrity promote an antioxidant environment.
Sorghum-based beverages were developed and the effects of decortication on nutritional composition biofunctional properties after a simulated gastrointestinal digestion analyzed. For that, white sorghum flours from whole (WS) decorticated (DS) grains obtained used to prepare beverages. They analyzed regarding chemical composition, minerals, phenolic acid contents. Moreover, bioaccessibility phenolics, proteins, potential bioactivity (ABTS<sup>+</sup> scavenging, ACE-I inhibition...
Physicochemical properties and structural characteristics of whole rice flours with different treatments (soaking, germination extrusion cooking) were studied. Water solubility, water absorption, crystallinity, adsorption isotherms (BET GAB models), glass transition temperature the samples determined. solubility absorption enhanced by cooking process (3.17–4.98 vs. 24.1–53.76 g/100 g 2.77–3.05 4.46–7.04 ml/g, respectively), but crystallinity was decreased (30–33 4–16%). Adsorption showed...
