Polyvinyl alcohol/sodium alginate (PVA/SA) hydrogel was successfully prepared by freeze thaw process. Without crosslinking agent, hydrogel was formed by using 3, 5 and 7 consecutive cycles of freeze thaw. Hydrogel can be formed by hydrogen bonding formation between OH-group of sodium alginate and polyvinyl alcohol throughout network. Scanning electron microscope reported that microstructure of hydrogel was well packed. The interconnect porosity was also observed. Differential scanning calorimetry exhibited that two exothermic peaks at temperature of 110℃ and 225℃ were observed due to evaporation of water molecule and melting temperature of hydrogel, respectively. The swelling behavior was rapidly increased within initial stage and then it was dimensionally stable. With low sodium alginate content, tensile strength was slightly superior, whereas low in vitro degradation behavior was observed. It was remarkable to note that polyvinyl alcohol/sodium alginate (PVA/SA) hydrogel exhibited outstanding properties for being as a medical material.

“…Thus, the increased paste viscosity represents the expansion of starch particles and the dissolution of straight-chain starch. 38 The peak viscosity of reconstituted rice decreased significantly, which is possibly due to starch expansion after extrusion puffing, and straight-chain starch was dissolved. The disintegrating value reflects the stability of starchy hot paste and its ability to withstand shearing at high temperatures.…”

With grain processing technology developing fast, lots of broken rice have been wasted every year. Reconstituted rice, as a rice byproduct, has higher nutrient value and rich flavor than natural rice. This paper aims to prepare a kind of reconstituted rice in broken rice, oats, soybeans, and potato starch with good taste and nutrients by extrusion puffing technology. The combined effect of oatmeal powder (20%), soybean flour (10%), potato starch (20%), squeeze temperature (80 °C), material moisture (31%), and screw speed (160 rpm) was used to formulate the product. The results showed that the absorbent rate, volume expansion rate, and blue iodine value of the reconstituted rice were significantly lower than native rice, while the solid dissolved material of rice soup was higher than that of native rice (p < 0.05). Increased hardness and chewiness and decreased elasticity and adhesion were obtained by texture determination. The paste properties of reconstituted rice were more lacking than that of natural rice. With respect to rheological properties, reconstituted rice was more viscous, while natural rice was more elastic. With respect to thermodynamics, the starting, end, and peak temperatures of reconstituted rice were higher than natural rice. Thus, reconstituted rice could improve the utilization of broken rice, enhance the deep processing of potato starch, drive the consumption of grains, and improve the value of products attached in the future.

“…The alginate microparticles portrayed a granular surface structure with substructures having plentiful smaller particles 115 . Lutfi et al 116 observed the granule surface of alginate‐based membrane was damaged when leached amylose and gum accumulated. The adsorption performance of sodium alginate when using as adsorbents could be enhanced by combining it with carbon nanotubes and graphene oxide 117 .…”

The emergence of biopolymers as polymer electrolyte membrane for non-Nafion used fuel cell application in recent years was an impactful finding. This review gives a different approach to researchers, by exposing the characterization analysis perspectives of developed materials from biomass sourcesalginates, carrageenan, cellulose, chitosan and polyhydroxyalkanoates. Their membrane performances are proven in this work through chemistry understandings, hence assuring a clear picture to gain information of these biopolymers' behavior as PEM. These five bio-precursor materials are believed to perform as high potential PEM alternatives, thus this study appeared to be an insightful guidance to the industry replacing high cost Nafion membrane to a lower cost membrane sources for future massive production economically benign. HIGHLIGHTS• Biopolymers are one of the promising natural sources to be utilized as the essential PEM in fuel cell • These biopolymers to be highlighted in this review are alginates, chitosan, carrageenan, cellulose and starch • Electronic biopolymers like carbon composites, hydrogels, nucleic acid, polyester, polysaccharide and protein imposed great features with their abundant functional groups, strong electrical conductivity, excellent ion conduction, versatility and stability
