“…29 Figure 5 depicts the disintegration of CMC in two stages, with two distinct peaks in which the same results showed by pure CMC of film CMC-A. A first breakdown stage occurs at 200-300 C and pyrolysis mechanism occurs at temperatures between 300 and 400 C. 30 However, because of a decrease in CMC concentration, the second peak disappears from sample films A to D when the Hc loading increased. As shown in Figure 3, T g of pure CMC films exists at 209 C in which small peak appears.…”

This study investigates the influence of hemicellulose (Hc) on the chemical composition, thermal stability, mechanical properties, and morphology of carboxymethyl cellulose (CMC). Hc was isolated from oil palm trunk and then added into CMC at 10–30 wt% to prepare Hc‐CMC films via solution casting method. The addition of Hc resulted in reduced visual transparency, rendering the blend films opaque. Fourier transform infrared spectroscopy verified the chemical interaction between Hc and CMC by revealing persistent and robust hydrogen bonding at specific spectral peaks (3483–3045 cm−1). The interaction between Hc and CMC was further indicated by the rougher interfacial structure as revealed in scanning electron microscopy (SEM). Thermal analysis via differential scanning calorimetry and thermogravimetry analysis indicated a decrement in thermal stability as Hc loadings increased in the CMC films. The highest tensile properties were observed in Hc‐CMC blend films at a 20 wt% Hc loading, showcasing notable enhancement about 23%. The 20 wt% Hc‐CMC blend films appeared as more suitable blending composition which having an enhanced physicochemical, thermal, and mechanical properties. This finding underscores its potential applicability in diverse industrial sectors, particularly in packaging applications.

“…It was observed that the spray-dried nostoc samples lose more mass at around 350 °C, being higher for CR and CE ( Table 7 ), which would indicate that these samples have a higher hydrocolloids content due to the fact that they present a prolonged slope in the TGA curve, starting around 200 °C [ 60 ] ( Figure 4 ), which confirms the TOC content ( Figure 2 ); this behavior is similar for hydrocolloids such as pectin, xanthan, CMC, and guar gum [ 4 , 5 , 11 , 58 , 61 , 62 , 63 , 64 ].…”

The search for new natural sources of hydrocolloids with stabilizing, thickening, and good binding capacity, from raw materials that are environmentally friendly and that contribute to the circular economy is a challenge for the food industry. The aim of the study was the preliminary characterization of a spray-dried hydrocolloid from high Andean algae Nostoc sphaericum. Four ecotypes of algae from Peruvian high Andean lagoons located above 4000 m were considered. The samples were collected in the period March—April 2021 and were subjected to a spray drying process in an aqueous medium. The characterization showed that the dehydrated nostoc ecotypes presented high protein and carbohydrate content, making it a potential material for direct use as a functional food for humans. The spray-dried product presented good stability for its use as a hydrocolloid, with zeta potential values (ζ), around 30 mV, evidencing the presence of -CO-, -OH, -COO-, and -CH groups, characteristic of polysaccharides, representing 40% of total organic carbon on average, giving it low water activity values and particle size at the nanometric level. Major minerals such as Ca (>277 mg/100 g), Mg (>19.7 mg/100 g), and Fe (>7.7 mg/100 g) were reported. Spray-dried nostoc is a hydrocolloid material with high potential for the food industry, with good nutritional content and techno-functional behavior.
