Accepted: 24/12/2014 Abstract A study was undertaken to evaluate the effect of Indian jujube pulp on the quality attributes of chicken sausages incorporated at 0%, 5%, 10% and 15% level (replacing lean meat) into the formulation of chicken sausages. The proximate, physico-chemical and sensory properties of sausages were analyzed. Among the different proximate and physicochemical parameters, a s...

Corresponding Author: Randa M. Osman Chemical Engineering and Pilot Plant Department, National Research Centre, Cairo, Egypt Email: [email protected] Abstract: The waste considered for this study was the effluent of the pulping process produced during the manufacture of pulp and paper in the Rakta integrated pulp and paper mill in Alexandria. The pulping process in Rakta mill is condu...

Kraft mills have the potential to pre-extract hemicellulose from wood as another value added product. The impacts of pre-extracting xylan on pulp and handsheet properties, sodium and sulfur balances, and chemical make-ups in the kraft pulping process of Eucalyptus grandis were assessed. Xylan extractions using white liquor, green liquor, and NaOH were done under varying extraction times, temper...

Chemical and morphological characterization of different parts of banana plant(Musa paradisica) (peduncle, leaf stalk and pseudo stem) were carried out in orderto assess their potentiality for chemical pulp. Each portion was tested forextractives, sodium hydroxide solubility, ash, lignin, cellulose and pentosancontents as well as their fiber length and width. These segmented parts werecharacter...

Wavelet neural networks (WNNs) were used to investigate the influence of operational variables in the soda-ethanol pulping of oil palm fronds (viz. NaOH concentration (10-30%), ethanol concentration (15-75%), cooking temperature (150-190 oC), and time (60-180 min)) on the resulting pulp and paper properties (viz. screened yield, kappa number, tensile index, and tear index). Performance assessme...

The effect of increasing the pulp yield by the addition of sodium borohydride (NaBH4) or polysulfide (PS) in softwood kraft cooking, i.e. enhancing the retention of glucomannan, on the physical properties of low-grammage handsheets was studied. In addition to the yield improvement, an increase in tensile index was observed, especially at lower degrees of beating. These higher yield pulps showed...

Residual lignin carbohydrate complexes (RLCC) were isolated enzymatically from spruce and pine pulp. The RLCCs contained 4.9–9.4% carbohydrates, with an enrichment of galactose and arabinose compared to the original pulp samples. The main carbohydrate units present in all studied RLCCs were 4-substituted xylose, 4-, 3and 3,6-substituted galactose, 4-substituted glucose and 4 and 4,6-substituted...

Abstract The delignification of birch chips during kraft pulping was investigated, targeting both the impregnation and cooking steps. Wood were impregnated using white liquor, liquor + NaCl, water or NaCl aqueous solution. Then, cooked in batch autoclaves applying same constant composition conditions for all samples. Pulp two fractions black (bulk centrifuged representing inside wood fibers) co...
