“…The spectral analysis of the CS film also displayed the presence of pigments existing in seaweed component that gives it the yellowish colour which the wavelength ranged between 422 cm -1 and 600 cm -1 . 40 This observation also verified the obtained and discussed optical properties' results of both stages in this study.…”

“…9,10 However, the extraction process is not environmentally and economically friendly because it requires high amount of chemical and energy consumption. 11 Moreover, it is believed that pure seaweed also contains other non-polysaccharide compounds that contribute to the film forming abilities of seaweed, including proteins and lipids. 12 Kappaphycus alvarezii (K. alvarezii) is a type of red seaweed which is largely cultivated for the production of the hydrocolloid known as kappa-carrageenan (κ-carrageenan).…”

Consequent to the recent global interest in biodegradable packaging in food and allied industries, this study investigated effect of blend ratio of the hybrid polysaccharide of corn starch and red seaweed on the properties of the developed film. The properties investigated include physical properties (thickness and water vapour permeability), mechanical properties (tensile strength, elongation and modulus) and optical properties while the complementary properties such as scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy were used to analyse possible chemical interactions within the films. Films manufactured with 100% corn starch (CS) exhibited the lowest quality while the films developed from seaweed (SE) blend exhibited higher quality. Based on complementary analysis result, there was an excellent blend of the filler and the polysaccharide matrix. The overall film properties improved with the increase of the blend ratio. The results of the Young's modulus (YM) complemented the results obtained for the tensile strength (TS) and the percentage elongation (E). The solubility value of the composite films justifies them as good candidate for the food packaging applications.

The review covers recent literature on the ocean as both a source of biotechnological tools and as a source of bio-inspired materials. The emphasis is on marine biomacromolecules namely hyaluronic acid, chitin and chitosan, peptides, collagen, enzymes, polysaccharides from algae, and secondary metabolites like mycosporines. Their specific biological, physicochemical and structural properties together with relevant applications in biocomposite materials have been included. Additionally, it refers to the marine organisms as source of inspiration for the design and development of sustainable and functional (bio)materials. Marine biological functions that mimic reef fish mucus, marine adhesives and structural colouration are explained.

“…To reduce the agglomeration, fiber must be made nano-sized. Smaller fibers result in better biocomposites due to high contact surface area, lower density, and good mechanical properties [9,16]. However, even nanofiber may not distribute homogeneously throughout the starch matrix.…”

Thermoplastic starch (TPS) reinforced by 1 wt % nanofiber cellulose (NFC) reinforcing from water hyacinth was produced. Ultrasonic vibration time (UVT) was applied to bionanocomposites during gelation for 0, 15, 30 and 60 min. Morphology of the NFC was investigated using Transmission Electron Microscopy (TEM). Scanning Electron Microscopy (SEM) and tensile tests were performed to identify the fracture surface and determine the mechanical properties of the bionanocomposites, respectively. The Crystallinity index (CI) of untreated and treated bionanocomposites was measured using X-ray Diffraction (XRD). The average diameter of NFC water hyacinth was 10-20 nm. The maximum tensile strength (TS) and modulus elasticity (ME) of the bionanocomposite was 11.4 MPa and 443 MPa respectively, after 60 min UVT. This result was supported by SEM which indicated good dispersion and compact structure.
