ethoxylated fatty acids or polyoxyethylene esters of fatty acids possess surface active characteristic depending on ethoxylation degree (glycol type used).they have a wide range of applications and are known by formulated trade names.fatty acids used as starting materials are obtained by the hydrolysis of fats and oils and thus the final products are fully biodegradable.the objective of this in...

introduction: health care is one of the most important sectors in the development of each country and disparities in their distribution will reduce the level of development. the aim of this study was to examine the access to healthcare and degree of development in health care resources in the west of iran in 2011. method: this was a cross-sectional and retrospective study. the study setting was...

This study was to determine the functional properties of fish protein hydrolysis produced from tilapia frame. used a factorial design where first factor different types proteolytic enzymes (E1 = bromelain, E2 papain) and second time (T1 5 hours, T2 6 hours) carried out with 3 replications. The results analysis showed that had significant difference on yield, degree hydrolysis, proximate, viscos...

The behaviour of different cellulosic fibres during acid hydrolysis has been investigated and the levelling-off degree of polymerisation (LODP) has been determined. The study included a bleached kraft pulp (both never-dried and once-dried) and two dissolving pulps (once-dried). Additionally, cotton cellulose from new cotton sheets and sheets discarded after long-time use was studied. Experiment...

in current study, protein hydrolysates were produced using microbial proteases of alcalase, protamex and flavourzyme from yellowfin tuna viscera. the results indicated that, protein hydrolysate from alcalase, had significantly higher protein content, nitrogen recovery and degree of hydrolysis than the others (p 0.05). the results of amino acids composition revealed that all hydrolysates were al...

White and Elman (1) in 1942 described condit,ions for the partial acid hydrolysis of proteins under which most of the tryptophane was retained undamaged. These hydrolysates appeared suitable for intravenous injection, as was reported briefly in the same communication. Studies have since been carried out by Risser, Schenck, and Frost (2) in these laboratories which demonstrate that partial acid ...

BACKGROUND Lignin-derived phenolic compounds are universal in the hydrolysate of pretreated lignocellulosic biomass. The phenolics reduce the efficiency of enzymatic hydrolysis and increase the cost of ethanol production. We investigated inhibition of phenolics on cellulase during enzymatic hydrolysis using vanillin as one of the typical lignin-derived phenolics and Avicel as cellulose substrat...
