Flaxseed, a Functional Food—Constituents and Their Health Benefits

Cellulose is an insoluble substance that is the main constituent of plant cell walls and of vegetable fibers, such as cotton. Lignin is a complex organic material deposited in the cell walls of many plants, making them rigid and woody.

For humans, being insoluble in water, cellulose, and hemicellulose are able to bind water which helps to increase fecal volume and thus promote regular bowel movements and help food move faster in the digestive tract. Therefore, both cellulose and hemicellulose may prevent constipation and reduce the risk of diverticular disease development (17). Moreover, cellulose and hemicellulose fibers can bind toxins and cholesterol present in foods to lower the risks of colon cancer development and hypercholesterolemia, respectively (17–23). Some dietary sources of cellulose include green vegetable leaves, whole-grain foods, flax, avocados, prune, and cauliflower.

In the early 1970s, Burkitt emphasized that the increase in the incidence of IBD in developed countries was related to a decrease in dietary fiber intake (13). Dietary fiber is a protective factor for CRC. It can maintain the balance of the intestinal flora by building a good intestinal barrier, and inhibiting inflammation and tumorigenesis (14–17). Cellulose is an insoluble dietary fiber and an abundant component of a vegetarian diet since it is found mostly in plant tissues (cell wall), such as vegetables and fruits. Cellulose is known to can regulate the composition of microbiota (18, 19). Additionally, it has anti-inflammatory and anti-neoplastic activities, which may be mediated by microflora. Some studies have shown that cellulose supplementation can reduce inflammation induced by dextran sulfate sodium (DSS) in mice, inhibit the occurrence of tumors, and reduce the tumor load of azoxymethane (AOM)-treated A/JMin+ mice by affecting the intestinal flora (14, 19, 20).

The Zn2+-Figure 1. Cellulose is a natural polymer, which shows good mechanical strength, blood compatibility and cytotoxicity [24]. Diethylenetriamine has been widely used as spacer to adsorb low-density lipoprotein [31]. Zn2+ is an indispensable nutrition microelement for human body. Therefore, these materials were used to synthesize the adsorbent. Freeze-drying method and coating method were used to enhance adsorption capacity and stability of the adsorbent, respectively. During the synthetic process, a series of beads with different compositions were characterized by the technique described above, respectively. Results indicate that the amino group content of wet-state diethylenetriamine-cellulose bead was 228.9 ± 4.24 μmol·g−1. The amount of chelated Zn2+ on wet-state diethylenetriamine-cellulose bead was 120.22 ± 10.16 μmol·g−1.

As a bio-based material, cellulose offers unique characteristics such as good biocompatibility, high tensile strength, thermal stability, and superior mechanical properties. Nonetheless, cellulose is poorly soluble in most of the common solvents and lacks the thermoplastic properties desired. Chemical and physical modifications of cellulose structure have been investigated (Hebeish and Guthrie 1981; Roy et al. 2009), primarily via esterification reactions with nitrate and acetic acid derivatives (Klemm et al. 2005) and etherification with methyl, carboxy methyl, and hydroxyalkyl derivatives (Fox et al. 2011).
