“…Based on Table 1, the YM value of the blank seaweed film was 2.15 GPa, which was higher than those seaweed-derived polymers such as alginate (1.88 GPa), carrageenan (1.1 GPa), and agar (1.3 GPa) (Ghosh et al 2010;Shankar et al 2015. However, the addition of OPS nanofillers up to 5% did not lead to significantly different YM values in the composite film as compared to the control film.…”

Composite films that utilize seaweed as a matrix and oil palm shell (OPS) nanoparticles as a reinforcing material were developed. The effects of loading OPS nanoparticle (0%, 1%, 5%, 10%, 20%, and 30%) into seaweed films were determined by analyzing the physical, mechanical, and morphological properties of the films. The seaweedbased film incorporated with OPS nanoparticles at a high concentration (20% w/w) achieved the highest tensile strength (44.8 MPa) and Young's Modulus (3.13 GPa). However, the film's hydrophobicity (contact angle = 47.3º) and percentage of elongation at break (2.10%) were reduced. Moreover, it was observed that excessive loading of nanofillers (> 20%) reduced the tensile strength and hydrophilicity of the film. This phenomenon was attributed to the agglomeration of OPS nanoparticles and the formation of large voids on the film surface. Thus, the relative effectiveness of the various tested nanofiller contents in enhancing the mechanical strength of the composite film were found to be ranked in the following order: 20%, 10%, 5%, 30%, and 1%.

“…Shankar et al [78] reported that incorporation of chitin nanofibrils in carrageenan based nanocomposites resulted in films having strong antibacterial activity against gram-positive foodborne pathogens. Various mixtures of chitin nanocrystals and oppositely charged carrageenan [79] and alginate [80,81] were developed with improved mechanical properties for therapeutic applications including wound dressing.…”

“…Subsequently, the viscous solution of agar/silver nanocomposite was poured into plastic plates and dried at room temperature before the analysis of films. Chitin nanofibrils were isolated from chitin after being hydrolyzed with HCl under strong agitation [78]. The unhydrolyzed fibers were filtered and the filtrate was centrifuged.…”

This review is a survey on ultrasonic application in selected carbohydrate polymers based upon available research reports. It covers a brief discussion on the fundamentals of ultrasound technology, before delving on the effects of ultrasound on specific polymers; pectin, chitin, starch, carrageenan and guar gum, their modification products and possible applications in food, pharmaceutical, biomedical and packaging sectors. Sonication generally leads to depolymerization and side chain break within molecules resulting into oligosugars. Oligosugars are widely used as prebiotics and specific delivery systems; moreover, nano sized products of sonication can be applied in diverse fields. Presently, ultrasonic is finding application in wider sectors therefore better understanding of the complex physico-chemical changes and mechanism of the action of high-intensity ultrasound and its effect on techno-functional properties of compounds would immensely fortify the application of ultrasonic technology.
