carboxymethyl cellulose from sugar beet pulp cellulose as a Hydrophilic Polymer in coating of mandarin
Journal of Food Engineering, 2004Co-Authors: Hasan Toǧrul, Nurhan ArslanAbstract:Sugar beet pulp cellulose was converted carboxymethyl cellulose (CMC) by etherification. The coating of mandarin surfaces with films formed by different emulsions containing CMC from sugar beet pulp cellulose as a Hydrophilic Polymer was carried out. Paraffin wax, beeswax and soybean oil; CMC with degree of substitution of 0.6670; Emulgin PE, triethanolamine, oleic acid and sodium oleate were used as hydrophobic phases, Hydrophilic Polymer and emulsifying agents in the coating of mandarins to extend postharvest life and to maintain their quality, respectively. Mandarins were stored in a storage chamber at 25 °C and at a relative humidity of 75%. Samples were taken at regular intervals for analysis. The changes in weight loss, pH, soluble solids, titratable acidity and ascorbic acid of the coated samples with storage time were investigated in comparison with the uncoated samples to determine the delay in the deterioration time of the samples. The effect of CMC as a Hydrophilic Polymer in coating emulsions on weight loss, pH, soluble solids, titratable acidity and ascorbic acid was also studied. The modified drying models describing the storage time dependence of weight loss were fitted to the experimental data and the model parameters in the equations were determined by multiple regression analysis. The coatings contributed to a lower reduction in pH. The coatings decreased the soluble solids and titratable acidity loses in comparison to the uncoated mandarins. The coating of mandarins delayed ascorbic acid loss. It was possible to extend the storage period with lower weight loss until 27 days by coating mandarin surfaces with emulsions containing CMC from sugar beet pulp cellulose as a Hydrophilic Polymer. It was found that the emulsion prepared using the mixture of soybean oil, CMC, sodium oleate and water was suitable for the coating of mandarins.

extending shelf life of peach and pear by using cmc from sugar beet pulp cellulose as a Hydrophilic Polymer in emulsions
Food Hydrocolloids, 2004Co-Authors: Hasan Togrul, Nurhan ArslanAbstract:Peach and pear were treated with different compositions of emulsions to extend shelf-life of fruits and to preserve the fruit quality. Paraffin wax, beeswax and soybean oil; carboxymethyl cellulose (CMC) with degree of substitution of 0.6670; Emulgin PE, triethanolamine, oleic acid and sodium oleate were used as hydrophobic phases, Hydrophilic Polymer and emulsifying agents in the coatings of peach and pear, respectively. The CMC obtained by etherification of the sugar beet pulp cellulose was used as a Hydrophilic Polymer. To investigate the post-harvest water loss of peach and pear, fruits were observed during storage while being subjected to dehydrating conditions in storage chamber at 25 °C and 75% relative humidity level. The changes in weight, pH, soluble solids, titratable acidity and ascorbic acid of the coated samples with storage time were measured at regular intervals throughout the storage period to evaluate the effect of storage period on fruit quality. The modified drying models describing the storage time dependence of weight loss were fitted to the experimental data and the model parameters in equations were determined by multiple regression analysis. Some of the coatings decreased the soluble solids, titratable acidity and ascorbic acid losses in comparison to the uncoated peaches and pears. The coating of peach and pear surfaces with emulsions containing CMC from sugar beet pulp cellulose as a Hydrophilic Polymer extended the shelf-lives of peach and pear to 12 and 16 days, respectively. It was found that a combination using beeswax as hydrophobic phase, triethanolamine and oleic acid as emulsifying agent, CMC as Hydrophilic Polymer and the emulsion containing soybean oil as hydrophobic phase, sodium oleate as emulsifying agent, CMC as Hydrophilic Polymers were suitable for the coating of peaches and pears, respectively.

Hydrophilic Polymer solubilization on norfloxacin solubility in preparation of solid dispersion
Powder Technology, 2014Co-Authors: Gabriel Onn Kit Loh, Yvonne Tze Fung Tan, Kok Khiang PehAbstract:Abstract The effects of single and binary Hydrophilic Polymers on the solubility and dissolution parameters of a poorly water-soluble drug, norfloxacin, via solid dispersions using the solvent evaporation method were investigated. Polyvinylpyrrolidone (PVP) was soluble, hydroxypropyl cellulose-low substituted (HPC-L) was partially soluble and polyacrylic acid (Carbopol) was insoluble in the solvent, acetone. All the single Hydrophilic Polymer dispersions increased the solubility and dissolution rate of norfloxacin. Norfloxacin/HPC-L solid dispersion demonstrated the highest solubility and dissolution, followed by norfloxacin/PVP and norfloxacin/Carbopol dispersions. The use of binary Polymers PVP/HPC-L further enhanced the solubility and dissolution of norfloxacin. On the contrary, binary Polymers PVP/Carbopol and HPC-L/Carbopol did not show a similar enhancement. The FTIR spectrum of norfloxacin/PVP/HPC-L showed no chemical interaction between the drug and Polymers. DSC thermogram exhibited a reduction in intensity and enthalpy of the drug peak. Disappearance of norfloxacin peak and reduction in crystallinity was observed in XRD analysis. In conclusion, for the enhancement of the solubility and dissolution rate of a poorly water-soluble drug, it is important for the single or binary Hydrophilic Polymers to be partially soluble during the solvent evaporation method. The Polymer not only improves the wetting of the drug but also provides a surface area for drug adsorption, modifying the solid state property of the drug.
