Fiber, dietary insoluble

Dietary fiber is the accepted terminology ia the United States for nutritional labeling. Total dietary fiber (I DF) and its subfractions, insoluble dietary fiber (IDF) and soluble dietary fiber (SDF), are defined analytically by official methods (3—5).

Analytical Methods. The samples were analyzed by standard AACC (21) procedures for moisture (air-oven method), protein (Method 46-13), crude fat (Method 30-25), crude fiber (Method 32-10), insoluble dietary fiber (Method 32-20) and ash (600°C, 3 hr). Starch content was determined by the polarimeter method (Method 76-20) and total sugars by Method 80-60. Color characteristics of the dried products were evaluated with the Hunter Color Difference Meter.

Total dietary fiber (TDF) content of potato dry matter is determined according to the AACC (2000) method 32-05 following the total dietary fiber assay procedure (Megazyme k-TDFR 01/05). This is a gravimetric method that is simpler and faster than other analysis methods. In addition to total dietary fiber content, both soluble and insoluble dietary fiber content can be determined by this method. 

Lignin polymers are often found in most plant structures in association with cellulose. The structure of lignin is not well defined, but lignin appears to be made up of polymers of propylbenzene with hydroxy and methoxy groups attached. Lignin is primarily hydrocarbon in nature and makes up a major portion of insoluble dietary fiber. 

A dried fruit outstanding to just be enjoyed for its soft texture, chewing, and rich taste, the prune has excellent micronutrient diversity. It s rich in both prebiotic (soluble viscous) and insoluble dietary fiber (including lignans), protein, vitamins, and several essential minerals. Prunes are notable for having a low glycemic load and so are recommended for suppressing appetite. 

In vitro digestibility (a-amylase) of raw quinoa starch was reported at 22%, while that of autoclaved, cooked, and drum-dried samples was 32%, 45%, and 73%, respectively (Ruales and Nair, 1994a). Saponins did not affect the digestibility of the starch. The total dietary fiber content in quinoa flour is affected by thermal treatment, while the insoluble dietary fiber fraction does not change with heat treatment (Ruales and Nair, 1994b).

Washed orange pulp was evaluated as an unconventional source of dietary fiber. The pulp is an excellent source of soluble and insoluble dietary fiber. Dried samples generally contain 25-45% pectins and 9-20% crude fiber. Several properties of the pulp are a function of its cellular components and must be considered in utilization as a food ingredient. Additional functional properties can be obtained by processing the hydrated pulp and have extended the potential use of this byproduct of the juice concentrate industry.

Psyllium, the seed husk of the plant Plantago genus, is an excellent source of soluble and insoluble dietary fibers.

The aleurone layer differentiates from the rest of the starchy endosperm approximately 2 weeks after pollination. There is clear evidence that aleurone cells synthesize starch granules after fertilization however, the starch granules disappear and the cell walls thicken as the grain matures. The cytoplasm of aleurone cells contains phytic acid bodies, protein bodies, and spherosomes or fat depots. The aleurone ceU walls contain soluble and insoluble dietary fiber, phenolics such as ferulic acid, ara-binoxylans, and P-glucans that fluoresce when viewed under a microscope equipped with ultraviolet light. 

Dry masa flours are currently being supplemented with common bean (Phaseolus vulgaris) and cactus (Opuntia spp.) flour. Both beans and cactus flours are rich sources of dietary fiber. The green-colored cactus supplemented tortillas, rich in both soluble and insoluble dietary fiber, are mainly consumed by diabetic and hyper-cholesterolemic people to lower glycemic index and blood cholesterol.
