In the production of oil from sesame (Sesamum indicum L.) seeds, a coproduct is obtained which rich in protein and fiber contents. Mixtures semi-defatted cake (SDSC) (0–20%) corn grits were processed single screw extruder at speed ranging 324 to 387 rpm improve nutritional value expanded extrudates. Chemical composition raw extruded materials, sectional expansion index (SEI), texture properties, color, paste viscosity, microstructure sensory analysis extrudates performed. The addition SDSC...

The process employed for the pulping and bleaching of sorghum straw was optimized prior to synthesis cellulose acetate. A 22 factorial central composite design carried out. variables considered were cooking time (1.5 2.5 h) dilute alkali concentration (0.75 1.25%) (30 35 min) bleach volume (20 25 mL) bleaching. comprised 49.43% α-cellulose, 19.18% hemicellulose 30.42% lignin. optimum conditions that maximize these processes h 1.25% (dilute concentration) at 90 °C, min mL (bleach volume) 80...

After the grinding stage of yam tubers, ultrasonic treatment (UT) is compared to traditional starch extraction. Different sonication conditions amplitude (12, 40, and 68%) time (3, 6, 9 min) are evaluated along two other treatments: a control (0% amplitude) 70% for 15 min, in order compare extraction method extreme conditions. Extraction yield, centesimal composition, color instrumental analysis, scanning electron microscopy, optical particle size, x‐ray diffraction, swelling power...

Corn is one of the most cultivated cereals in Brazil. However, its grains are constantly exposed to contamination by mycotoxins. grits used food industry produce a large variety corn products such as canjiquinha, cultural easily purchased Brazilian consumer at low prices. Some studies have demonstrated high this product aflatoxins (AFs), representing potential risk exposure due contamination. In study, efficacy gaseous ozonation was evaluated on levels and microbial grits. The application...

WITH BARBADOS CHERRY (Malphigia emarginata D.C.).Edibles films are an alternative to synthetic materials used for packing food products.Barbados cherry is rich in vitamin C and carotenoids.The aim of this study was characterize develop by casting from cassava starch, lyophilized Barbados pulp glycerol.The were characterized with respect thickness, water vapor permeability (WVP), solubility, C, β carotene mechanical properties.The interaction glycerol reduced film thickness.An increase...

Extruded products were prepared from a corn flour and dehulled carioca bean (Phaseolus vulgaris, L.) blend using single-screw extruder. A central composite rotate design was used to evaluate the effects of extrusion process variables: screw speed (318.9–392.9 rpm), feed moisture (10.9–21.0 g/100 g) level (4.8–55.2 on specific mechanical energy (SME), sectional expansion index (SEI), longitudinal (LEI), volumetric (VEI) density (D) extrudates. The instrumental texture also analyzed....

The influence of whey protein concentrate (WPC), feed moisture and temperature on the physicochemical properties rice-based extrudates has been investigated. WPC (0.64-7.36g/100g rice) was extruded under 5 (16.64-23.36g/100g) (106.36-173.64°C) established by a 32 central composite rotational design. Physicochemical [color, porosimetry, crystallinity, water solubility absorption, pasting properties, reconstitution test, proximate composition, amino acids, minerals electrophoresis] were...

The aim of this work was to formulate cookies using extruded flour from by-products rice and common beans industries, such as broken split old bean grains, in order make available foods with added nutritional value other options consumers. market ready eat high quality products is increasing the world considering new habits life style modern Different proportions black (whole – WBF or peeled grain - PBF) pre-gelatinized flours were used prepare by partially replacing corn starch original...

Filmes provenientes de biopolímeros (polissacarídeos e proteínas) apresentam-se como alternativa ao uso derivados petroquímicos, possibilitando a formação matrizes contínuas, otimização parâmetros pH tipo plastificante pode resultar em materiais com propriedades melhoradas. Neste estudo, filmes amido mandioca produzidos por casting foram avaliados quanto adição extrato proteico soja (EPS), glicerol do meio. O aumento da concentração EPS levou escurecimento dos filmes, solubilidade aumentou o...

Novel formulations of passion fruit shell flour and rice blends were processed on a single-screw extruder, into value-added extrudates. The effects extrusion processing variables die temperature, feed moisture, content the sectional expansion (SEI), longitudinal (LEI), water absorption (WAI), solubility (WSI) indices extrudates evaluated using central composite design. caused marked effect all independent studied (SEI, LEI, WAI, WSI). Passion used in this study contained 56.76% crude fiber....

Abstract Gluten-free bakery products are usually deficient in dietary fiber and inferior sources of protein. Studies that have assessed sensory characterization prepared with orange pomace scarce. This study evaluated the employment 30% rice-based pregelatinized composite flours (containing 15, 25 or 35% blended 5% soy protein isolate) on gluten-free biscuits. The target was investigation nutritional profile consumer’s acceptance three short dough sweet biscuit samples. Thermoplastic...

Estudaram-se as características de farinha bagaço jabuticaba fermentado e algumas propriedades funcionais (índice expansão índice solubilidade) dos extrusados elaborados a partir deste arroz, em proporções que variaram 11,59 25% (bagaço/arroz). A foi avaliada quanto à distribuição do tamanho partícula, cor, sabor aroma, composição centesimal, minerais fibras. Algumas das desta foram comparadas com farinhas doce (sem fermentar) arroz polido. O extrusor utilizado para obtenção...
