Photodegradation of Cassava and Corn Starches [PDF]

open access: possibleJournal of Agricultural and Food Chemistry, 2001
The baking expansion properties of sour cassava starch (Polvilho azedo) are attributable to photochemical starch degradation induced by heterolactic fermentation after sun-drying. This study investigated the effects of UV irradiation on the different structural levels of cassava starch as compared to those of corn starch and dextrins.

Cassava starch films reinforced with lignocellulose nanofibers from cassava bagasse

open access: yesInternational Journal of Biological Macromolecules, 2019
Cassava bagasse, a high-fiber coproduct of cassava starch processing, was used to produce lignocellulose nanofibers (LCNF) to apply as reinforcement in cassava starch films. LCNF-reinforced cast starch films were evaluated for changes in structural, thermal and mechanical properties and compared with control films reinforced with commercial grade ...

Preparation and Characterisation of Thermoplastic Starches from Cassava Starch, Cassava Root and Cassava Bagasse

Macromolecular Symposia, 2005
AbstractSummary: Thermoplastic starches (TPS) based on cassava starch have been produced by extrusion at 120 °C, using glycerol as plasticizer. Three forms of cassava starch were employed, viz: cassava root (CR), cassava bagasse (CB) and purified cassava starch (PCS).

Depolymerisation of cassava starch

Carbohydrate Polymers, 1999
A factor in the use of native cassava starch for commercial food production is its variability. Agronomic factors and processing protocols alter the performance of starch in food products. Work carried out at the University of Nottingham has indicated that cassava is particularly susceptible to starch conversion when being extruded. Also, cassava seems

Modeling cassava starch saccharification with amyloglucosidase

Applied Biochemistry and Biotechnology, 1996
A solution of α-amylase liquefied cassava starch, 30% (w/v), was saccharified with amyloglucosidase at 45°C, pH 4.5, in a batch reactor in the presence and absence of added glucose. Reactor conversion results were modeled with a multisubstrate model that considers intermediate dextrins of starch hydrolysis, reversibility of some reactions, substrate ...

CHARACTERIZATION OF FERMENTED CASSAVA STARCHES

Journal of Food Biochemistry, 1993
Fermented and nonfermented cassava (Manihot utilissima Pohl) starches from Colombia and Brazil were studied. The DSC themograms obtained at high water contents (water:starch 3.1 to 4.2) showed that starch fermentation decreased both the temperature of gelatinization (Tmax) and that of final gelatinization.
