Extracts of wheat bran and barley husk with solvents different polarity were analyzed to determine the concentration bioactive compounds (phytic acid, saponins, flavonoids, total phenolic profile) their antioxidant activity by DPPH ABTS assays. The results showed that phytic acid in was higher than husk. saponins inverse concentrations bran. highest extraction phytochemicals 80% ethanol 50% acetone chromatograph profile presented a greater caffeic contained kampferol. properties...

Probiotics are effective coadjuvancy against human affections. To confer their beneficial effects to humans, probiotics adhere and colonize the intestine. Then, they must survive gastrointestinal conditions (~108–1010 cfu/day). However, concentration dose produce effect reduced. Synbiotics combination of prebiotics, can increase probiotics. Microencapsulation is an efficient approach protect synbiotics during passage through intestinal tract. In this article, we thoroughly reviewed different...

Este estudio evalúa los cambios morfológicos y estructurales en la proteína de cebada durante germinación. Los granos no germinados exhibieron una organización estructural bien definida, con pericarpio, capa aleurona cuerpos proteicos intactos, sin mostrar evidencia hidrólisis. gránulos almidón estaban incrustados matriz proteica compacta. Después germinación, aparecieron huecos celulares, el pericarpio se desintegró parcialmente las capas internas quedaron expuestas. Las estructuras...

Introduction: The antimicrobial effect of hibiscus acid (HA) alone and in combination with nalidixic (NA) on multi-antibiotic-resistant Shiga-like toxin-producing Escherichia coli (STEC) Salmonella Typhimurium (ST) was evaluated CD-1 mice. Methodology: minimum inhibitory concentration (MIC) bactericidal (MBC) for NA HA were determined against both STEC ST. Fifteen sets 6 mice each utilized: groups exposed orally to 5 log10 colony forming units a pool 3 ST strains, another STEC; acted as...

Antibiotic-resistant Salmonella strains were isolated from saladette and red round type tomatoes, an analysis done of the antibacterial activity roselle calyx extracts against any identified strains. One hundred tomato samples 100 collected public markets. Each sample consisted four whole tomatoes. was by conventional culture procedure. Susceptibility to 16 antibiotics tested for standard test. The effect (water, methanol, acetone ethyl acetate), sodium hypochlorite acetic acid...

ABSTRACT The objective of this study was to develop with thermoplastic extrusion amaranth starch derivatives and characterize evaluate their functionality as encapsulating agents Bifidobacterium breve ATCC 15700 Lactobacillus casei 334 during spray drying. survival both probiotics storage at different water activities two temperatures, viability in a food model system, tolerance simulated gastrointestinal tract were determined. Native chemically modified obtain phosphorylated, acetylated,...

Microorganisms represent a viable option for the control of phytopathogens. From surface healthy mangoes, different bacteria were isolated. For all isolated bacterial strains, we determined their antimicrobial activity against fungal strain that caused anthracnose in mangoes and Alternaria alternata, both culture medium directly on mangoes. The strains with highest antifungal identified by sequencing 16s rRNA gene. Two species Serratia identified: marcescens nematodiphila. Finally,...

Abstract Background and objectives The aim of this study was to develop a wall material using rice starch ( Oryza sativa ) optimize the microencapsulation vanilla extract by spray drying. Native hydrolyzed, succinated, extruded, characterized. Findings peak viscosity modified starches reduced from 3,875 cP <100 effect modification step. gelatinized extrusion according gelatinization enthalpy (∆ H J/g). Natural encapsulated, most optimal conditions for drying process were air inlet...

Abstract The objective of this study was to evaluate the influence pH, bile salts and different storage conditions at two temperatures (30 4 °C) on viability free microencapsulated Lactobacillus paracasei . Microspheres encapsulating L. were obtained using an extrusion method. efficiency 87.6%, diameter 70 µm zeta potential 7.22 ± 0.05 mV. Encapsulated showed higher resistance stomach pH compared cells. evaluated under four conditions: fresh, suspended in a solution with 4, saline...

The mixtures of blue cornmeal and orange bagasse were processed in a single screw laboratory extruder. We used an experimental design, central composite rotatable, where the factors as follows: extruder die temperature (153–187°C), feed moisture (146.4–213.6 g/kg), concentration (32.7–167.3 g/kg). results analyzed by surface methodology response to evaluate effect these variables on expansion index, bulk density, penetration force, specific mechanical energy, water absorption, solubility...

In the search for new ingredients that counteract some of problems associated with consumption meat and products like high contents saturated fat, salt, cholesterol, absence dietary fiber, presence synthetic additives, Hibiscus sabdariffa calyxes have shown good colorant, antimicrobial, antioxidant properties. This research paper studies use H. roselle directly or by means extracts in products. Although its application is incipient, results are promising. The vibrant red color makes suitable...

Abstract Multidrug‐resistant Salmonella serotypes (M‐RSs) were isolated from coriander, and an analysis done of the antibacterial activity roselle calyx extracts against any identified strains. One‐hundred coriander samples collected markets. was by culture procedure. Susceptibilities to sixteen antibiotics determined for strains standard test. The effect four (water, methanol, acetone ethyl acetate), sodium hypochlorite, acetic acid colloidal silver M‐RS isolates evaluated on contaminated...

The objective of this work was to carry out a double chemical modification in rice starch: the first acid hydrolysis optimization as preparatory step for second modification, which consisted phosphating. For process, independent variables time (h) and concentration (N) were evaluated. We obtained estimated coefficients adjusted model significance responses viscosity profile (Vmax), water solubility index (WSI), absorption (WAI), onset temperature (To), peak (Tp) ending (Te). values predicted...

Abstract Background and objectives Most of the snacks in market contain a single cereal show nutritional deficiencies. The aim study was to optimize conditions extrusion process for snack with barley/corn mix their physicochemical evaluation, amino acid content, protein digestibility, resistant starch as healthy snack. Findings regression model indicated that variables water absorption index, solubility hardness can be explained by models. Expansion index showed no significant effect....
