BACKGROUND Riverine particles undergo a rapid transformation when they reach estuaries. The rapid succession of hydrodynamic and biogeochemical regimes forces the particles to flocculate, settle and enter the sediment pool. The rates and magnitudes of flocculation depend on the nature of the particles which are primarily affected by the types and quantities of organic matter (OM). Meanwhile, th...

Guar is a valuable industrial crop, widely grown in India and Pakistan. The potentialities of guar seed are based on complex polysaccharide called galactomannan (gum) which present its endosperm. newly developed variety Karan Guar-14 has good content (30.2%) high viscosity profile (3412 cp) increases export values. It medium maturing (90–95 days) an average, it gives higher grain yield (1222 kg...

Guar, the most popular vegetable, is tolerant of drought and a valuable industrial crop enormously grown across India, Pakistan, USA, South Africa for pharmaceutically cosmetically usable galactomannan (gum) content present in seed endosperm. Guar genotypes with productive traits which could perform better differential environmental conditions are utmost priority genotype selection. This be ach...

3. SACN have reviewed the available scientific evidence for components under consideration for inclusion in the Codex definition on dietary fibre for nutrition labelling purposes, using the SACN frame work for assessing evidence (SACN 2002). These components include total fibre, non starch polysaccharides, fibre components from cereal, fibre components from fruit and vegetables, starch, resista...

In recent years worldwide interest has grown towards the development of mucoadhesive drug delivery systems. These systems are capable of adhering to body's mucosal surfaces for an extended period of time, releasing their drug content in a retarded manner. The use of biopolymers, and in particular phytopolymers, could provide a natural basis for the development of such systems. The aim of this s...

The effects of different hydrocolloids on the gelatinisation behaviour of hard wheat flour were investigated. Influence of guar, xanthan, Arabic, carboxy methyl cellulose (CMC) and tragacanth gums on wheat flour was studied using micro viscoamylograph. It was found that all hydrocolloids except tragacanth greatly modified the gelatinisation properties of wheat flour. Guar and xanthan significan...
