A multiple-unit floating drug delivery system based on gas formation technique was developed, in order to prolong the gastric residence time and to increase the overall bioavailability of the dosage form. The floating bead formulations were prepared by dispersing nevirapine together with calcium carbonate in a mixture of sodium alginate and hydroxypropyl methylcellulose solution and then drippi...

background: edible films and coatings have potential benefits for food packaging, particularly meat products. these coatings prevent weight loss and texture changes during shelf life by reducing moisture loss in fresh and frozen meat products. in this study, effect of calcium alginate edible coating on microbial and chemical properties of refrigerated lamb meat over a period of  5 days was inve...

The impact of calcium-induced fat droplet aggregation on the microstructure and physicochemical properties of model mixed colloidal dispersions was investigated. These systems consisted of 2 wt% whey protein-coated fat droplets and 4 wt% modified starch granules heated to induce starch swelling (pH 7). Optical and confocal microscopy showed that the fat droplets were dispersed within the inters...

BACKGROUND Glucoamylase is an exo-type enzyme that converts starch completely into glucose from the non-reducing ends. To meet the industrial requirements for starch processing, a glucoamylase with excellent thermostability, raw-starch degradation ability and high glucose yield is much needed. In the present study we selected the excellent Carbohydrate-Activity Enzyme (CAZyme) producer, Bispora...

starch could used as ingredient fillers, binders and crushers in tablet manufacture. Amylum is also defined carbohydrates from plant, results photosynthesis, which stored part certain plant backup food mixture two type structure different polysaccharides that contains (17-20) % amylose (80-83) amylopectin. Destination study this for know the formulation of mucoadhesive tablets with fully gelati...

BACKGROUND The proportion of starch disappearing from the small intestinal lumen is generally lower in ruminants than in monogastric animals, and there are indications that the starch digestion capacity in ruminants is limited. OBJECTIVES Milk-fed calves were used to study the rate-limiting enzyme in starch hydrolysis and to quantify starch fermentation in ruminants. METHODS Forty male Hols...

Alginate is a family of natural polysaccharides, widely used in industry and medicine for many applications, with its non toxic nature, gentle sol/gel transition procedure and low cost, alginate inferior biomechanical properties have limited its utility especially in tissue engineering. Additionally, ionically cross-linked alginate hydrogels generally lose most of their initial mechanical and s...

In this study, the Acid Black 1 dye containing effluent collected from a dyeing unit was examined with the alginate extracted from the marine brown algae, Sargassum sp. for its removal. Batch experiments were carried out using standard Jar test apparatus. Fourier Transform InfraRed (FT-IR) Spectroscopy and Scanning Electron Microscopy (SEM) techniques were used to characterize the raw algin...

Concanavalin A (Con A) purification method was developed by using calcium alginate cellulose beads containing cobalt (II) ions. The yield of Con A obtained by calcium alginate cellulose beads containing cobalt (II) ions was 6.8% as compared to 3.65% yield obtained by Sephadex G-50 method. Purified Con A agglutinated trypsin-treated rabbit red blood cells. FTIR spectra showed the presence of β s...
