Produção e caracterização estrutural, molecular e morfológica de nanocristais a partir de diferentes amidos e sua aplicação em biofilmes
(Universidade Estadual Paulista (Unesp), 2017-06-07)
O efeito do padrão cristalino do amido na obtenção e na morfologia, características estruturais, moleculares e físico-químicas de nanocristais de amido (NCA) e sua aplicação em biofilmes foram estudados. Amidos de mandioca, ...
Behavior of Peruvian carrot (Arracacia xanthorrhiza) and cassava (Manihot esculenta) starches subjected to heat-moisture treatment
(Wiley-Blackwell, 2014-07-01)
Peruvian carrot and cassava starches were isolated, adjusted to 30 and 35% moisture, and heated at 90 degrees C for 8 h. Structural and physicochemical characteristics of the treated starches were evaluated and compared. ...
Electroactive sugars, organic acids and sugar alcohol analysis in wine using anion-exchange chromatography with electrochemical detection
(2019-06-01)
The present work describes an easy, rapid and sensitive alternative methodology for simultaneous detection of sugars (glucose, fructose and arabinose), organic acids (gluconic, glucuronic and glucaric acids) and sugar ...

Structural and functional characteristics of selected soft wheat starches
(Amer Assoc Cereal Chemists, 2002-03-01)
Starches from eight soft wheat samples (two parent lines and six offspring) were isolated; relationships between their structures and properties were examined. Branch chain-length distributions of amylopectins were determined ...
Multivalent sialylation of beta-thio-glycoclusters by Trypanosoma cruzi trans sialidase and analysis by High Performance Anion Exchange Chromatography
(Springer, 2016-10)
The synthesis of multivalent sialylated glycoclusters is herein addressed by a chemoenzymatic approach using the trans-sialidase of Trypanosoma cruzi (TcTS). Multivalent β-thio-galactopyranosides and β-thio-lactosides were ...
Purificação e caracterização de uma gentioexaose obtida de botriosferana por hidrólise ácida parcial
(Sociedade Brasileira de Química, 2008)
A hexa-oligosaccharide was obtained by partial acid hydrolysis from botryosphaeran, an exopolysaccharide (EPS) β(1→3; 1→6)-D-glucan type, produced by the ascomyceteous fungus Botryosphaeria rhodina. The ...
Anatomical and biochemical changes in the composition of developing seed coats of annatto (Bixa orellana L.)
(SPRINGER, 2009)
Seeds of Bixa orellana (L.) have a sclerified palisade cell layer, which constitutes a natural barrier to water uptake. In fact, newly fully developed B. orellana seeds are highly impermeable to water and thereby dormant. ...
