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.

High Temperature Stable Separator for Lithium Batteries Based on SiO2 and Hydroxypropyl Guar Gum

et al. 2015

A novel membrane based on silicon dioxide (SiO2) and hydroxypropyl guar gum (HPG) as binder is presented and tested as a separator for lithium-ion batteries. The separator is made with renewable and low cost materials and an environmentally friendly manufacturing processing using only water as solvent. The separator offers superior wettability and high electrolyte uptake due to the optimized porosity and the good affinity of SiO2 and guar gum microstructure towards organic liquid electrolytes. Additionally, the separator shows high thermal stability and no dimensional-shrinkage at high temperatures due to the use of the ceramic filler and the thermally stable natural polymer. The electrochemical tests show the good electrochemical stability of the separator in a wide range of potential, as well as its outstanding cycle performance.

“…The major cluster bean cultivating countries are India, Pakistan, USA, Italy, Morocco, Germany, and Spain (Punia et al, 2009). India produces about 80% of the world cluster bean production (Tripathy and Das, 2013). Cluster bean is grown especially in the arid regions of India (Rajasthan, Haryana, Gujarat and Punjab) for gum purpose, whereas it is grown for vegetable purpose in other parts of India (Rai and Dharmatti, 2013).…”

Cluster bean is an important legume cultivated mostly on marginal and sub marginal lands of arid and semi-arid regions. Overall, India produces around 80% of global cluster bean production. It is cultivated on more than 4 m ha in India, Rajasthan alone accounts for around 80% of the area and production. Owing to its demand in the international market, it has been introduced in the non-traditional growing areas like Andhra Pradesh, Tamil Nadu, Karnataka, Maharashtra and Chhattisgarh. Further, its cultivation is also being taken up under irrigated conditions during summer. Cluster bean seed (endosperm) is a source of a natural hydrocolloid (galactomannan/'guar gum'). The gum has unique abilities with multiple commercial applications like textile, printing, paper, cosmetics, mining, pharmaceutical, petroleum, natural gas, well drilling and oil industries. Green pods are nutritionally rich and are routinely consumed as vegetable especially in northern and western parts of India. Additionally, cluster bean has been reported to have beneficial effects when cultivated as an intercrop. Cluster bean meal (high protein content) obtained from seed coat and germ cell is an excellent feed for monogastric animals. Cluster bean cultivars with high gum content (>32%) and viscosity (4000-5000 cps) are more preferred for export. The value of cluster bean exports from India has increased from Rs 242 crores (1994) to Rs 2100 crores . This review presents the various aspects of cluster bean cultivation and its emergence as an important industrial crop.Key words: Applications, Cluster bean, Cultivation, Galactomannan, Markets, Processing.[Cluster bean Cyamopsis tetragonoloba (L.)] is an annual legume crop mostly grown under resource constrained conditions in arid and semi-arid regions (Kumar, 2005). Cluster bean is a deep rooted plant of Leguminosae (Fabaceae) family known for drought and high temperature tolerance (Kumar and Rodge, 2012). The major cluster bean cultivating countries are India, Pakistan, USA, Italy, Morocco, Germany, and Spain (Punia et al., 2009). India produces about 80% of the world cluster bean production (Tripathy and Das, 2013). Cluster bean is grown especially in the arid regions of India (Rajasthan, Haryana, Gujarat and Punjab) for gum purpose, whereas it is grown for vegetable purpose in other parts of India (Rai and Dharmatti, 2013). Cluster bean can be used for multiple purposes (vegetable, cattle feed/fodder or green manure). It is a good source of nutrition and its tender green pods are also a cheap source of nutrients. Further cluster bean meal and seed are used as high protein cattle feed (Rai and Dharmatti, 2013). Cluster bean gum is a naturally occurring hydrocolloid present in the endosperm of seed (also known as 'Guaran'). It has emerged as the most important biologically produced non-toxic, eco-friendly and safe agro-chemical. The gum is produced primarily from ground endosperm after dehusking the seed (Sabahelkheir et al., 2012). Owing to its varied uses, cluster bean has emerged as a ne...
