It is well known that dietary fiber helps to relieve and prevent constipation, and there are a number of scientific papers, including systematic reviews and meta-analyses on the effects of naturally derived dietary fiber on bowel movements. In recent years, there has been an increase in the manufacture of dietary fiber ingredients obtained from food raw materials, and these are now commonly ava...

Abstract Carbon fiber/polyimide composites were prepared by high temperature molding process with carbon fiber, 450 °C resistant polyimide resin and related additives as raw materials. Effects of prepreg content, porosity post-treatment on properties studied, fracture shape was analyzed. Results show that shear fiber can be improved more than 50% after removing sizing agent, mechanical are the ...

This paper presents the results of a preliminary assessment towards the potential estimation of solar process heating in paper industry in India. To begin with, data for (i) classification of paper mills on the basis of size and feedstock used (ii) extent of cogeneration in paper mills (iii) annual paper production (feed stock wise) (iv) specific thermal energy requirement for process heating e...

The equilibrium moisture content (EMC) of biomass affects transportation, storage, downstream feedstock processing, and the overall economy of biorenewables production. Torrefaction is a thermochemical process conducted in the temperature regime between 200 and 300 °C under an inert atmosphere that, among other benefits, aims to reduce the innate hydrophilicity and susceptibility to microbial d...

Carbon fiber materials become more and more important for many applications. Unlike metal the technological parameters and certified quality control mechanisms for Raw Carbon Fiber Materials (RCF) have not yet been developed. There is no efficient and reliable testing system for in-line inspections and consecutive manual inspections of RCF and post laminated Carbon Fiber Reinforced Plastics (CF...

INTRODUCTION Cassava is one of the few root crops known and is an important food source in many countries of Africa, Latin America and in some Asian countries. In Venezuela, for instance, the root is eaten in a number of ways such as in soups, as casabe (cassava flat cake), as naiboa (cassava with raw sugar and grated white cheese formed into a flat cake) and as buñuelos (fried cassava dough ba...

This study is aimed at achieving the optimum conditions of hydrothermal treatment and acetylation of Populus fiber to improve its oil sorption capacity (OSC) in an oil-water mixture. The characteristics of the hydrolyzed and acetylated fibers were comparatively investigated by FT-IR, CP-MAS 13C-NMR, SEM and TGA. The optimum conditions of the hydrothermal treatment and acetylation were obtained ...

Chia (Salvia hispanica L.) constitutes a potential alternative raw material and ingredient in food industry applications due to its dietary fiber content. Gum can be extracted from its dietary fiber fractions for use as an additive to control viscosity, stability, texture, and consistency in food systems. The gum extracted from chia seeds was characterized to determine their quality and potenti...

The chemical composition of several non-woody plant fibers (bast fibers from flax, hemp, kenaf, jute; leaf fibers from sisal, abaca and curaua; and giant reed), which are used as raw materials for pulp and papermaking, has been evaluated. Particular attention was paid to the composition of the lipophilic compounds and the structure of the lignin polymer since they are important components of th...

This note introduces the use of distributed polarization x-talk measurement for raw polarization maintaining fiber (PMF) quality inspection, PMF coil winding process monitoring, PMF coil adhesive curing and stress release monitoring, overall PMF coil quality inspection, and temperature induced stress determination. PMF birefringence temperature variation can also be precisely measured. The use ...
