Sugar beet pulp, source

Other Insoluble Fiber Sources. Other iasoluble fiber sources are commercially avaUable as weU, including fiber from sugar-beet pulp, a by-product of sugar productioa. Table 3 Usts other iasoluble fiber sources. 

To improve production of rhamnogalacturonase by Aspergillus aculeatus CBS 115.80 shake flask ejqjeriments were performed on several substrates. Cross reactivity was found after transfer to thamnose in combination with galacturonic acid and on apple pectin, citrus pectin, beet pectin and sugar beet pulp. No cross reactivity was found after transfer to meda containing simple carbon sources such as sucrose, glucose, fiuctose, rhamnose or galacturonic acid. 

Another possible exploitation of annual plant residues, after the separation of their foodstuff, is their conversion into polyols by oxypropylation. In this context, the whole of the residue is involved in the transformation, providing a convenient and ecological source of macromonomers. A typical example of this strategy is described in Chapter 12, in the case of sugar beet pulp, which is poor in xylans and cannot therefore be considered as a possible source of furfural. 

Several sources of cellulose have been used to obtain cellulose nanofibres including banana residues [87, 90], soybean souree [99], cotton [100], wheat straw [86], bacterial cellulose [101-104], sisal [88, 105], hemp [89, 106], sugar beet pulp [107, 108], potato pulp [109], bagasse [110], stems of cacti [111] and algae [112],... 

The main sources of cellulose are issued to i) primitive organisms like bacteria ( Acetobacter xylinum), algae (ex Valonia, Cladophora, Microdictyon) ii) plants (ex wood, cotton, flax, ramie, jute, parenchyma of sugar beet pulp...) and iii) envelop of sea animals belonging to the Ascidians family (ex tunicate). 

The sugar industry produces many by-products along with sugar. These include molasses, bagasse, beet pulp, alcohol, pulp for paper industry, press-mud fertilizer, and a power source from burning bagasse. 

Most of the European sugar production is based on the exploitation of sugar beet (SB) and the corresponding industrial process generates enormous amounts of pulp as a by-product. This rather intractable fibrous solid, mostly made up of polysaccharides and pectin, has found some uses as fatilizer and animal feed, but the possibility of converting it into a source of polymeric materials had eluded researchers until it was shown that this remarkably inert natural product could in fact be readily converted into a viscous liquid polyol by a simple bulk oxypropylation treatment [8, 9]. 

Beet pulp - the residue of the roots after the sugar has been extracted an excellent feed for stock. This can be sold wet for inclusion in cattle or sheep rations or as a bagged dry feed, very popular for horses, as a source of energy.
