Starch based carbon nanotubes-iron oxide (CNT-IO) and nanotubes-zirconium (CNT-ZO) nanocomposites (NCs) were fabricated using facile microwave irradiation technique from different plant-based starch sources namely Tapioca sago (TS), Hordeum vulgare (HV) Eleusina coracona (EC) metal precursor solutions. The prepared NCs studied by characterization techniques such as SEM, TEM, XRD, Raman spectros...

We report that fluorescent carbon nanodots (Cdots) can act as an optical probe for quantifying Sn(II) ions in aqueous solution. C-dots are synthesized by carbonization and surface oxidation of preformed sago starch nanoparticles. Their fluorescence is significantly quenched by Sn(II) ions, and the effect can be used to determine Sn(II) ions. The highest fluorescence intensity is obtained at a c...

This study aimed to produce new edible coatings based on the mixture of sago starch, cellulose nanofiber (CNF), glycerol, and tween-80.The effect starch (5–10 g starch/100 ml distilled water), CNF (0.5–20% w/w), glycerol (10–30% tween-80 (0.5–10% w/w) concentration contact angle (CA), water vapor permeability (WVP), oxygen (PO2) tensile strength (TS) properties were optimized using factorial ex...

Enhancement of pullulanase production by Raoultella planticola DSMZ 4617 using optimized medium formulation was investigated in batch fermentation using 500-mL shake flask. The fermentations were carried out, firstly, to search for a suitable cultivation medium for enzyme production and followed by the evaluations on the influence of carbon and nitrogen sources and also initial culture pHs on t...

The aim of the present study is to develop a novel biomaterial from natural resources which can be used for various biomedical applications. In this work, composite films containing soya protein (SY) and sago starch (SG) were prepared by solvent casting methodology; these films were cross linked with glutaraldehyde to improve their mechanical properties. The films prepared were characterized fo...

Starch is one of the most widespread and used biopolymers in different applications such as in the paper, textile, food, pharmaceutical and cosmetics industries (Richardson & Gorton, 2003). Even starch is useful in various industrial fields, its use as a native form has been restricted by some limitations (high viscosity, low solubility in cold water, paste instability, etc.) in specific applic...

Abstract Red bell pepper is categorized as a perishable horticultural commodity with short shelf life. Damage in red peppers generally characterized by changes the texture of fruits, wrinkled and other damage due to improper storage. Proper postharvest handling must be done maintain product quality prevent spoilage. Efforts are being made keep fresh life applying an edible coating. This study a...
