Obesidade e fibra dietética: destaque para a fibra de caju

Overweight and obesity continue to be an important global health challenge andarisk factor for an increasing set of chronic non-communicable diseases. The role of dietary components in promoting health has deserved considerable attention in the prevention of chronic diseases associated with food, among which dietary fibers stand out. This work aims to perform a bibliographic review regarding the physiological a...

Caracterização morfológica da semente seca e mobilização de reservas durante a ...

Information about the morphology, chemical composition and reserve mobilization is important in understanding the establishment of native and exotic species. The purpose of this study was to describe the morphology, chemical composition, and mobilization of reserves during germination of noni (Morinda citrifolia L.). Biometric and morphological analyzes were performed with 100 randomly selected dried seeds. Oth...

Avaliação química e estrutural da semente de moringa

Moringa (Moringa oleifera Lam.) is a plant that has been used instead of aluminum salts in water treatment. The aim of this work was to determine the composition and the morphology of the moringa seeds. Cotyledons contain a great amount of proteic bodies. This material was observed with Xylidine Ponceau pH 2.5 stain. Anionic material and starch in the cotyledon cells were not detected by Toluidine blue and PAS ...

Corn starch based films treated by dielectric barrier discharge plasma

Cold plasma is an innovative strategy to strengthen the polysaccharide-based films characteristics. This study evaluated the effects of dielectric barrier discharge (DBD) plasma on the hydrophilic character, water vapor permeability (WVP), and tensile properties of corn starch-based films. Starch films were exposed to plasma processing operating at an excitation frequency of 200 Hz for 10, 15, and 20 min. DBD p...

Cashew apple fiber prevents high fat diet-induced obesity in mice: an NMR metab...

Dietary fiber intake plays an important role in the prevention of obesity. This study aimed at investigating the effect of cashew fiber without low molecular weight compounds (CABwc) on obesity prevention and metabolomics in a murine model of diet-induced obesity. Mice were fed a chow diet (CD), a high-fat diet (HFD) or a high-fat diet supplemented with CABwc (10%) (HFD-CABwc) for 15 weeks. The body weight, abd...

Effects of industrial cashew nut processing on anacardic acid content and aller...

Cashew nuts are important both nutritionally and industrially, but can also cause food allergies in some in- dividuals. The present study aimed to assess the effect(s) of industrial processing on anacardic acids and al- lergens present in cashew nuts. Sample analyses were performed using liquid chromatography coupled with mass spectrometry, SDS-PAGE and immunoassay. The anacardic acid concentration ranged from ...

NMR study of galactomannans from the seeds of mesquite tree (Prosopis juliflora...

The seed gum from Prosopis juliflora is a galactomannan polysaccharide, which is located in the endosperm. Regarding P. juliflora galactomannan structural studies, there are reports on galactose substitutional pattern, but supporting data by NMR correlation studies are scarce. In this work, a procedure to obtain P. juliflora gum without contamination was employed and the gum was studied by NMR spectroscopy. Ove...

Ciclopeptídeos de Pseudofusicoccum sp., um fungo endofítico isolado de Manilkar...

Os fungos endofíticos são uma rica fonte de metabólitos de importância agrícola e farmacêutica, por isso o presente estudo teve como objetivo identificar quimicamente os metabólitos secundários produzidos pelo fungo Pseudofusicoccum sp., isolados dos galhos de Manilkara sp. visando identificar o potencial biotecnológico da linhagem em produzir substâncias de interesse industrial. Inicialmente, o fungo foi culti...

Extração e separação de flavonoides do extrato da casca do maracujá

Este trabalho objetivou separar os flavonoides presentes no extrato da casca de maracujá, usando SAB constituído por etanol, sal e água. Avaliou-se a influência dos sais (NH4)2SO4 e K2HPO4, e da concentração dos componentes do SAB sobre a partição e a recuperação dos flavonoides. Em ambos os sistemas, ao coeficiente de partição dos flavonoides foi superior a 70 e sua recuperação esteve acima de 99 % e de 92 % n...
