Food processing industiy

Category 1 Polymers, which are directly extracted or removed from biomass. Certain polysaccharides such as starch, cellulose, and proteins like casein and gluten constitutes this categoiy. By nature, all this are hydrophilic and somewhat ciystalline-factors and creates problems while processing and performance, especially in relation to packaging of moist food products. However, their excellent gas barrier property makes it suitable for its utilization in food packaging industiy. 

Many applications of enzymes exist today in many, veiy different industries. In this chapter, first a short description is given of the various industries where enzymes are used as processing aids or processed into final products. Further in this chapter examples from the detergent, feed, textile and food industiy are worked out in detail, highlighting technical, commercial and social aspects to reckon with when developing and applying enzymes for these purposes. 

Separations by chromatography are carried out in the pharmaceutical and food industiy, for instance, the isolation of specific polysaccharides. As an example a mixture of glucose and fractose is separated by elution chromatography. The differences of the physical properties of isomers are often very small with the consequence that most of the known separation processes cannot be economically used. Here chromatography is an excellent tool. This is true for racemic mixtures. Enantiomers are separated by the apphcation of chiral stationary phases. Sometimes ten-side micellar solutions or mixtures of solvents are used as the mobile phase. 

Flotation is a powerful mineral beneficiation tool that has wide potential in effluent treatments in the following industries oil industry, engineering industry wastes, daily wastes, food industiy, textile fiber wastes, cellulose fibers, rubber wastes, asbestos wastes, polymeric wastes, paper industry wastes, dyes, electroplating industiy, vegetable wastes, poultry processing wastes... 

Supercritical fluid CO is said to have become a mainstay in extraction processes in the food industiy (decaffeination, extraction of hops) and apparel diy cleaning, where it is said to be the best, gentlest, most thorough cleaning method now available. Carbon dioxide is also said to be considered the best supercritical fluid for the dyeing process, is naturally occurring, chemically inert, physiologically compatible, relatively inexpensive and readily available.
