Preparation and Characterization of Edible Films Based on Soy Protein Isolate-Fatty Acid Blends

Functional property optimization of sodium caseinate-based films incorporating functional compounds from date seed co-products using response surface methodology

“…4 ), this reinforcing effect can be ascribed to the formation of crosslinks between furfural and NaCas' primary amine groups, resulting in a more cohesive protein matrix. In agreement with our results, Nayak et al 43 reported a significant increase in TS of soy protein isolate-fatty acid blends upon the addition of furfural. This improvement in the stiffness of composite films has been attributed to the ability of the incorporated furfural to act as an efficient crosslinking agent by interacting with the free amino groups present in soy protein isolate leading to the formation of a rigid and cohesive network.…”

“…Likewise, an improvement in the thermal stability of soy protein isolate-based films was recorded after incorporation of furfural. 43 Recently, Zhang et al 44 attributed the high thermal resistance of phenolic resin crosslinked with furfural to the high molecular weight and stable structure of furan-based heterocycles.…”

“…5d). Previously, a very rough lm surface was observed by Nayak et al 43 when inspecting SEM images of soy protein isolate lms incorporating oleic acid and furfural. Such increase in lm surface roughness was mainly ascribed to the crosslinking of furfural with protein chains along with oleic acid droplets aggregation within the polymeric matrix.…”

Development of crayfish bio‐based plastic materials processed by small‐scale injection moulding

“…Besides, additives such as reducing agents may be helpful in order to reduce the average molecular weight of protein aggregates, thus facilitating both mixing and moulding processes. Thus, some authors studied the influence of reducing agents on the properties of thermo‐moulded wheat gluten bioplastics, soy protein isolate, starch or flax fibres . The effect of adding a denaturing agent, such as urea has also been analysed on bioplastics processed by extrusion or compression moulding .…”

Properties of chitosan/soy protein blended films with added plasticizing agent as a function of solvent type at acidic pH

“…These groups in SPI together with hydroxyl groups from the bounded water and glycerol can easily interact with carbonyl moieties through intra-and intermolecular hydrogen bonding in the peptide and carboxyl groups of the protein structure [24]. In chitosan, O-H stretching that is an indication of intermolecular hydrogen bonding occurred in the same region with N-H stretching [3,25].…”
