The colon specific drug delivery systems based on polysaccharides; locust bean gum and chitosan in the ratio of 2 : 3, 3 : 2 and 4 : 1 were evaluated using in vitro and in vivo methods. The in vitro studies in pH 6.8 phosphate buffer containing 2% w/v rat caecal contents showed that the cumulative percentage release of mesalazine after 26 h were 31.25+/-0.56, 46.25+/-0.96, 97.5+/-0.26 (mean+/-S...

BACKGROUND Most of the previous studies regarding the effects of gel-forming fibres have considered the gastric emptying of liquid or solid meals after the addition of pectin or guar gum. The influence of locust bean gum, on gastric emptying of nutrient semisolid meals in humans has been less well studied, despite its common occurrence in foods. Using a standardised ultrasound method, this stud...

We describe an integrated and straightforward new analytical protocol that identifies plant gums from various sample sources including cultural heritage. Our approach is based on the identification of saccharidic fingerprints using mass spectrometry following controlled enzymatic hydrolysis. We developed an enzyme cocktail suitable for plant gums of unknown composition. Distinctive MS profiles ...

In Africa a variety of indigenous cereals, legumes and tubers are cultivated as starchy food crops. These include sorghum, millet species including pearl millet, finger millet, teff and white and black fonio, and African rice as cereals; cowpea, Bambara groundnut, African yambean and West African locust bean as legumes; and Zulu round potato and the Livingstone potato as tubers. Many of these p...

The effect of adding xanthan gum and locust bean gum at low concentrations (0.15% w/w) on the freeze/ thaw stability of white sauces prepared with native starches from four different sources (corn, waxy corn, potato, and rice) was investigated. Linear viscoelastic properties were taken as structural indicators and these and syneresis as indicators of the freeze/thaw stability of the sauces. The...

The effect of the interaction of iota-carrageenan (ICG) or lambda-carrageenan (LCG) with locust bean gum and carboxymethylcellulose on the properties of ice cream was studied employing a mixture design approach. A model formulation was employed with of 5% (w / w) of hydrocolloids like stabilizers. Hydrocolloids mixture effect on ice cream properties (base viscosity, ice-cream overrun, hardness,...
