Preparation and characterization of cassava starch acetate with high substitution degree
This study presents a scalable method to acetylate cassava starch (CS), resulting in cassava starch acetate (CSA), a highly hydrophobic polymer suitable for coating and food packaging. FTIR confirmed the formation of CSA, with degrees of substitution (DS) ranging from 1.9 to 2.9. Thermogravimetric analysis indicated improved thermal stability with higher DS. SEM revealed structural changes in CSA. Structural characterization via NMR confirmed DS values and revealed regioselective substitution at the C6 position.

New hydrocyclone design for high starch yield: Effect of cylindrical-conical length proportion on the starch, sulfur and protein separation efficiencies
This research aimed to optimize hydrocyclone design for efficient separation of starch and impurities in cassava starch production. Parameters such as cylindrical-conical length (Lcy/Lco ratio) and underflow-overflow diameter (Du/Do ratio) were adjusted to enhance separation efficiency. The designed hydrocyclone achieved high separation efficiencies for starch, sulfur, and protein, providing improved refining and recovery capabilities in the cassava starch production process.

Extraction and characterisation of starch from cassava (Manihot esculenta) agro-industrial wastes
This study explores extracting starch from cassava agro-industrial wastes, particularly cassava peel and bagasse, as a non-edible source. A developed extraction method maximized starch yield, with cassava peel starch exhibiting a significantly higher yield compared to bagasse. Characterization through SEM, FTIR, and XRD showed similarities in morphology and crystalline phase with commercial cassava starch. These findings suggest potential applications of cassava peel and bagasse starch as biodegradable food packaging materials.

Cleaner and faster method to detect adulteration in cassava starch using Raman spectroscopy and one-class support vector machine
The study proposes Raman spectroscopy as a rapid, cost-effective method for detecting adulterants in cassava starch, addressing food quality control concerns. It evaluates one-class support vector machine (OC-SVM) and soft independent modelling by class analogy (SIMCA) as data treatment approaches, with OC-SVM demonstrating superior sensitivity, specificity, and accuracy in detecting adulterations.
