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.

Pectin-cerium (IV) tungstate composite (Pc/ CT) has been prepared by sol gel method at room temperature. The composite ion exchanger has been characterized using X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy and Fourier infrared spectroscopy. The ion exchange capacity, pH titrations, thermal stability and distribution coefficient of composite ion exchanger were investigated. The Na ? ions exchange capacity of the Pc/CT has been observed higher (1.4 meq g -1 ) as compared to its inorganic counterpart (0.8 meq g -1 ). Pc/CT composite ion exchanger was thermally stable and retained about 60 % of its ion exchange capacity up to 400°C. The distribution study has inferred more selective the Pc/CT for Zn 2? as compared to other metal ions. The adsorption efficiency of Pc/CT was tested for methylene blue removal dye from aqueous phase. The removal of dye followed pseudo-second-order kinetics.

“…In the final degradation phase, 34% of the residual mass was completely degraded around 800ºC, which indicates that the sample has high thermal stability. DTA profiles show the endothermic peaks are at 56ºC and 145ºC and the exothermic peaks were observed between 243ºC and 575ºC, which indicates that is the temperature for thermal depolymerization of pectin chain 17 .…”

Biopolymers are considered as promising materials for replacing polythene bags in packaging industries. To reduce the non-degradable packaging wastes, biocomposite films were made from polyvinyl alcohol, reinforced with chemically treated pomegranate fibers and glycerol as plasticizer. The composition of the film was optimized using response surface methodology using fibre, pectin and polyvinyl alcohol concentrations as factors. The optimization was based on the influence of the factors on the responses of the biocomposite film. A rotatable central composite design was used. The responses considered were thickness, tensile strength and elongation. The optimized film had 0.15 mm thickness, 1.531 MPa tensile strength and 44.01% elongation, made with 2.77% fibre, 1.23% pectin and 1.94% polyvinyl alcohol. Thus the optimized packaging film may be useful in the food packaging.
