Fiber fraction

Detergent Methods. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) methods (2), later modified for human foods (13), measure total insoluble plant cell wall material (NDF) and the cellulose—lignin complex (ADF). The easily solubilized pectins and some associated polysaccharides, galactomaimans of legume seeds, various plant gums, and seaweed polysaccharides are extracted away from the NDF. They caimot be recovered easily from the extract, and therefore the soluble fiber fraction is lost. [Pg.71]

All VGCF was graphitized prior to composite consolidation. Composites were molded in steel molds lined with fiberglass reinforced, non-porous Teflon release sheets. The finished composite panels were trimmed of resin flash and weighed to determine the fiber fraction. Thermal conductivity and thermal expansion measurements of the various polymer matrix composites are given in Table 6. Table 7 gives results from mechanical property measurements. [Pg.151]

A discontinuous fiber composite is one that contains a relatively short length of fibers dispersed within the matrix. When an external load is applied to the composite, the fibers are loaded as a result of stress transfer from the matrix to the fiber across the fiber-matrix interface. The degree of reinforcement that may be attained is a function of fiber fraction (V/), the fiber orientation distribution, the fiber length distribution, and efficiency of... [Pg.831]

Morehouse 200 wet mill (Morehouse Industries, Fullerton, CA), operated at 3600 rpm. The finely dispersed slurry was filtered through a 230-mesh vibrating screen to remove the coarse fiber fraction. The residue was washed a second time with 0.02% NaOH for 1 hr and passed through the wet mill and screen to remove additional solubles ... [Pg.183]

The fiber fraction was washed several times with water, ratio 1 5, the washings being added to the starch fraction (Figure 2). Final traces of starch were removed from the fiber by incubation with 2% alpha-amylase (Sigma Chemical Co., type V-A from hog pancreas) for 16 hr at 37°C, and washing several times with distilled water before freeze-drying. [Pg.183]

For example, the minimum fiber fraction for a carbon-fiber-reinforced epoxy matrix composite is 0.03. [Pg.483]

Dietary fiber has been suggested to play a protective role against chemically-induced toxicity (1) and against colon cancer (2). However, the mechanism(s) by which dietary fiber modulates chemical toxicity or colon cancer has not been well studied. The fiber fraction of the diet is resistant to mammalian digestive enzymes and consequently dietary fiber is not absorbed from the small intestine (3). However, certain types of dietary fiber specifically fermentable fibers, including the pectic substances and hemicelluloses, are readily digested by the intestinal microflora (4,5). Pectic... [Pg.44]

Cationic starch is mainly adsorbed by the small fiber fractions and filler particles, according to their high specific surface. At low cationic starch levels (0.5%), only the small fiber fraction is saturated and rendered cationic a mosaic system is established which results in small flocks and good retention, but poor drainage. Increasing the... [Pg.682]

The resin in the parenchyma cells is mainly composed of fatty acid esters (fats and waxes) and sterols. When wood is pulped, this resin usually remains encapsulated inside the parenchyma cells, while the oleoresin becomes dispersed in the liquor. This is particularly the case with spruce parenchyma cells, which have minute pores and rigid cell walls. Pine parenchyma cells have larger pores and release their resin more readily (Table 5-1). The resin content of acid sulfite spruce pulps can be effectively lowered by fiber fractionation. The situation is different for pine pulps in which the proportion of parenchyma cells is lower. [Pg.86]

Bark can roughly be divided into the following fractions fibers, cork cells, and fine substance including the parenchyma cells. The fiber fraction is chemically similar to that of the wood fibers and consists of cellulose, hemicelluloses, and lignin. The other two fractions contain large amounts of extractives. The walls of the cork cells are impregnated with suberin, whereas the polyphenols are concentrated in the fine fraction. [Pg.100]
