“…The physicochemical properties of sago starch shown in Table 4 have been shown to depend on the specie and the time of harvest [150]. Sago starch consists of oval granules with an average size of 30 mm and the XRD studies showed that sago starches exhibited C-type diffraction pattern [149].…”

Tropical roots and tubers, grains, cereals, and fruits are crops that have served as staple foods for millions of people throughout the hot and humid regions of the world for many centuries. Some of these crops grow in abundance with little or no artificial input. These tropical crops contain starch of as one their major component, which has made them good sources of starch that could be used as pharmaceutical excipients. In recent time, some of these starches have been investigated for use as fillers, glidants, binders, and disintegrants in pharmaceutical tablet formulations. The diversity of the starches from these plants has shown that some of the starches can be used in place of commercially available chemically modified starches. Their application as excipients can add value to some of these neglected and underutilized crops and also provide starch with special properties for specific applications. This review summarizes the present knowledge on the starches extracted from tropical plants that have been evaluated as pharmaceutical excipients and their potential usefulness, with a view to providing suggestions for needed research to adopt the utilization of these starches in the pharmaceutical industry.

“…The transition temperature of the sago starch film exhibited a sharp endothermic peak at 238 °C indicating film degradation temperature due to the chitosan portion (td). The characteristic temperature of the starches depends on the morphology and degree of crystallinity within the starch molecule (Ahmad et al, 1999). With the glycerol incorporation into the sago starch-chitosan films, the DSC thermograms illustrated a broad endothermic peak at 165 to 280 °C corresponding to the degradation temperature of 182.2 °C of the glycerol.…”

The objective of this study was to investigate physical and mechanical properties, such as thickness, water vapor permeability, tensile strength, elongation at break, differential scanning calorimetry (DSC) and microstructure of composite edible films. The film was prepared by casting sago starch from sago palm (Metroxylon sagu) as film base with 10-50 %w/w glycerol as plasticizer and adding bulk chitosan as a reinforcing material (0.1, 0.3, and 0.5 %w/w). The continuous, homogenous and transparent films were obtained. With regard to mechanical properties, tensile strength decreased when the percentage of glycerol increased. Elongation at break (%E) improved with increasing percentage of glycerol from 10 %w/w to 50 %w/w. However, water vapor permeability properties diminished in all samples when the percentage of chitosan increased. The morphological study of the composite films exhibited rougher surfaces with increasing chitosan in the films. DSC thermograms showed that glycerol incorporated into composite films diminished the onset temperature (T0) and degradation temperature (Td). Having these physical and mechanical properties, this edible film has a potential to apply for food packaging purposes. Moreover, this edible film is proved to be more cost-effective and environmentally friendly.

Modified soils (MSs) are being increasingly used as geo-engineering materials for the sedimentation removal of cyanobacterial blooms. Cationic starch (CS) has been tested as an effective soil modifier, but little is known about its potential impacts on the treated water.This study investigated dissolved organic matters in the bloom water after algal removal using cationic starch modified soils (CS-MSs). Results showed that the dissolved organic carbon (DOC) could be decreased by CS-MS flocculation and the use of higher charge density CS yielded a greater DOC reduction. When CS with the charge density of 0.052, 0.102 and 0.293 meq/g were used, DOC was decreased from 3.4 to 3.0, 2.3 and 1.7 mg/L, respectively.The excitation-emission matrix fluorescence spectroscopy and UV 254 analysis indicated that CS-MS exhibits an ability to remove some soluble organics, which contributed to the DOC reduction. However, the use of low charge density CS posed a potential risk of DOC increase due to the high CS loading for effective algal removal. When CS with the charge density of 0.044 meq/g was used, DOC was increased from 3.4 to 3.9 mg/L. This study suggested, when CS-MS is used for cyanobacterial bloom removal, the content of dissolved organic matters in the treated water can be controlled by optimizing the charge density of CS. For the settled organic matters, other measures (e.g., capping treatments using oxygen loaded materials) should be jointly applied after algal flocculation.
