The effects of whey protein (12%) and sodium alginate (0.5%) on chemical, microbial and sensory changes and shelf life in kilka during frozen storage are investigated for up to 6 months. Total bacteria count and Staphylococcus bacteria counts(2 / 51 and 1 / 44 log CFU/g) in coated samples showed decrease in comparison with control samples(3.21- 2.28 log CFU/g). Moisture of coated samples had s...

The present study was conducted to evaluate the effectiveness of the edible coating of Cinnamon Essential Oil (CEO) and Rosemary Essential Oil (REO) incorporated into alginate coating to maintain chemical and sensorial characteristics of chicken meat under refrigeration conditions. Firstly in vitro antioxidant activity of essential oils was evaluated. Then fresh c...

This study investigates the use of microencapsulation by fluidised bed coating for the protection of ascorbic acid during long-term storage under simulated tropical conditions. Microencapsulation materials, loading levels, fluidised bed processing conditions and the results of storage trials were evaluated. Cellets® 350 is a suitable base material, whereas sugar spheres are not suitable due to ...

In the present study, effects of edible coatings using sodium alginate (SA) and sodium alginate in combination with ascorbic acid (AA) on the shelf-life extension of strawberries at 4±1°C was studied. A factorial experiment was performed based on a randomized complete block design with four replications. The treatments included control (distilled water), SA (1%, 2%, 3% w/v), SA in combination w...

The goal of this research is to develop innovative damage-responsive bacterial-based self-healing fibers (hereafter called BioFiber) that can be incorporated into concrete enable two functionalities simultaneously: (1) crack bridging functionality control growth and (2) healing when a occurs. BioFiber comprised load-bearing core fiber, sheath bacteria-laden hydrogel, an outer impermeable strain...

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...

The purpose of this work was to develop a multiparticulate system exploiting the pH-sensitive property and biodegradability of calcium alginate beads for intestinal delivery of ceftriaxone sodium (CS). CS was entrapped in beads made of sodium alginate and sodium carboxymethylcellulose (CMC), acacia, HPMC K4M and HPMC K15M as drug release modifiers. Beads were prepared using calcium chloride as ...

Meat is one of the most challenging food products in the context of maintaining quality and safety. The aim of this work was to improve the quality of raw/cooked meat by coating it with sodium alginate (A), chitosan (C), and sodium alginate-chitosan polyelectrolyte complex (PEC) hydrosols. Antioxidant properties of A, C, and PEC hydrosols were determined. Subsequently, total antioxidant capacit...

in the past decade, electrospinning as a facile and effective means in producing nanofibers with diameters ranging from microns down to a few nanometers has been developed and considered important. in this work, electrospinning of an interesting natural biopolymer, sodium alginate, has been investigated. the results showed that water solution of sodium alginate cannot be electrospun into nanofi...
