⑤
Food industry
Cellulose is mainly processed into dietary fiber in the food industry. Modern
medicine has proved that people are susceptible to digestive diseases, especially
intestinal disease, when the body lacks fiber. Dietary fiber is one indispensable
ingredient of future nutrients.
⑥
Materials industry
As shown in Fig.
10.9
, the production of various products from lignocellulose
would be a new development direction in the materials industry. Especially, the
development of cellulose copolymerization technology is attractive.
⑦
Chemical raw materials
As shown in Fig.
10.10
, the production process for chemical raw materials is
mainly achieved through fermentation. Lignocellulose can be broken down to
monosaccharides by enzymes, which not only can be used to produce chemical raw
materials but also can produce a range of fermentation products as substrate for the
fermentation industry.
(3) Hemicellulose industrial systems
Hemicellulose can be used for the production of chemical raw materials that can be
used in the pharmaceutical, energy, and feed industries.
①
Chemical raw materials
As shown in Fig.
10.11
, using hemicellulose to produce xylose, xylitol, and furfural
is the main form of production in the hydrolysis industry. In addition, glycerol and
ethylene glycol can be produced through the degradation. These products should be
gradually replaced by microbiological processes.
