guar gum and whey proteins concentrate (wpc-35) were used as functional additives to improve the functional characteristics (hardness and meltability) of the na-caseinate-based imitation cheese. also, the alterations in the composition, sensory acceptance, color, and texture caused by these ingredients were evaluated. imitation cheeses were formulated with three levels each of wpc (0, 1.5, and ...

This paper reports the studies available on the characterization and chemical/biochemical analysis of natural dyes; extraction of colorants from different natural sources; effects of different mordants and mordanting methods; conventional and non-conventional methods of natural dyeing; physico-chemical studies on dyeing process variables and dyeing kinetics; development of newer shades and anal...

The macroscopical characters of the leaves, leaf constants, physico-chemical constants, extractive values, colour, consistency, pH, extractive values with different solvents, micro chemical test, fluorescence characters of liquid extracts and leaf powder after treatment with different chemical reagents under visible and UV light at 254mn, measurement of cell and tissues were studied to fix some...

Physico-chemical properties reflect the functional and structural characteristics of a protein. The comparative study of the physicochemical properties is important to know role of a protein in exploring its molecular evolution. A number of online and offline tools are available for calculating the physico-chemical properties of a single protein sequence. However, a tool is not available for a ...

The purpose of this paper is to list and discuss briefly some of the causes of chemical and physico-chemical disintegration of concrete and to point out some methods that can be used to study these causes. In this paper a distinction is made between physico-chemical (or chemico-physical) and mechanical causes of failure. Processes involving changes in chemical composition (chemical reactions pr...

−Monitoring parameters were evaluated for a bioventing process that was designed to treat soils contaminated with diesel fuel. Statistical analyses were conducted to evaluate correlations between total petroleum hydrocarbon concentrations in the contaminated soil and physico-chemical parameters of soil such as microbial counts, dehydrogenase activity, and n-alkane/isoprenoid ratio. The correlat...

The objective of this paper deal with the physico chemical aspects of certain colouring plants namely. Bixa orellana Linn. (Leaves) and Lawsonia inermis Linn (Leaves). The determined data under the physico chemical, chromatographic and spectrophotometric studies can be taken as a pharmacopoeial standards.

Djendjen River is one of the largest rivers in the region of Jijel (Algeria). Human activities such as urban discharges, industrial, agricultural, and livestock have significant effects on the quality of water. The present study attempts to evaluate the quality of water along the banks of the Djendjen River at different sampling sites, using physico-chemical and bacteriological methods. The col...

Hydroxyapatite nanoscale particles (nHA) were prepared by wet chemical precipitation using four different synthesis methods. Differences in physico-chemical properties including morphology, particle-size, and crystallinity were investigated following alteration of critical processing parameters. The nanoparticles were also studied using X-ray diffraction (XRD), Fourier Transform infrared spectr...
