“…These results are in agreement with the XRD patterns reported for NCS in the literature. 52 , 53 Nevertheless, as shown in XRD spectra, cassava starch is a semicrystalline material. However, a significant amount of changes in the crystal structure of cassava starch was observed during microwave and freeze-drying processes (see Figure 3 ).…”

Starch and its derivatives have recently emerged as a sustainable and renewable alternative for petroleum-based expanded polystyrene (EPS) and expanded polypropylene (EPP) foam materials. In this study, biodegradable foam materials were prepared from cassava starch using a novel dual modification technique, combining microwave treatment and freeze-drying. The foam materials were prepared from starch solutions microwaved over different intervals. The starch-based foam materials were characterized using Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), 13 C nuclear magnetic resonance ( 13 C-NMR) spectroscopy, and compression set test. Moreover, the water absorption capacities and density values of the foam materials were measured according to ASTM standards. The biodegradability test was carried out according to the aerobic compost environment test. The lowest water absorption capacities of 65.56% and 70.83% were exhibited for the cassava starch foam sample (MWB) prepared at a 20 s microwave treatment time and immersed in distilled water for 2 and 24 h, respectively. Furthermore, the lightweight cassava starch-based foam materials displayed density ranging from 124 to 245 kg/m 3 . The biodegradation test exhibited significant biodegradation of over 50% after 15 days for all the foam materials prepared. These results suggest that the dual-modified cassava starch-based biodegradable foams show potential in sustainable packaging applications by replacing petroleum-based materials.

Starch, the predominant carbohydrate in nature, serves as the primary energy source for various physiological activities in humans. Characteristic starches from tropical crops, such as cassava, banana, jackfruit, and breadfruit, mango, and canistel have gained attention due to their diverse and multiscale structures, distinct physicochemical properties, processing characteristics, and myriad applications. This review provides a comprehensive summary of the research progress on starch from various tropical crops. Specifically, the extraction technology, amylopectin content, multiscale structure, physical and chemical properties, processing technology, and applications of starch are reviewed. The advancements, application prospects, and research suggestions on starch from characteristic tropical crops are also discussed, which provides theoretical guidance for enhancing the processing level of related products and diversifying food sources.

“…The water-sensitivity of starch [ 5 ], due to the presence of hydroxyl groups in its structure [ 6 ], make the starch-based adhesives binders less effective. This shortcoming can be solved using different chemical modifications of starch in order to incorporate hydrophobic behavior, such as acid hydrolysis, acetylation, esterification, etherification, oxidation, cross-linking and blending of polymers [ 7 , 8 , 9 , 10 ]. Most of said approaches use toxic compounds or do not improve the properties of the material in a sufficient way [ 11 , 12 , 13 ].…”

A novel strategy for improving wet resistance and bonding properties of starch-based adhesives using enzymatically polymerized lignosulfonates and carboxylic acids as additives was developed. Therefore, lignosulfonates were polymerized by laccase to a molecular weight of 750 kDa. Incorporation of low concentrations (up to 1% of the starch weight) of 1,2,3,4-butanetetracarboxylic acid (BTCA) led to further improvement on the properties of the adhesives, while addition of greater amounts of BTCA led to a decrease in the properties measured due to large viscosity increases. Great improvements in wet-resistance from 22 to 60 min and bonding times (from 30 to 20 s) were observed for an adhesive containing 8% enzymatically polymerized lignin and 1% BTCA. On the other hand, the addition of citric acid (CA) deteriorated the properties of the adhesives, especially when lignosulfonate was present. In conclusion, this study shows that the addition of the appropriate amount of enzymatically polymerized lignosulfonates together with carboxylic acids (namely BTCA) to starch-based adhesives is a robust strategy for improving their wet resistance and bonding times.
