Sugar cane juice

C18-0020. Glycolic acid (HOCH2 CO2 H), a constituent of sugar cane juice, has a p Zg of 3.9. Sketch the titration curve for the titration of 60.0 mL of 0.010 M glycolic acid with 0.050 M KOH. Indicate the stoichiometric point, the buffer region, and the point of the titration where pH- p. S a. Sketch the curve qualitatively without doing any quantitative calculations. 

The species commonly encountered in sugar-cane juice is Leuconostoc esenteroides. The cells are surrounded by a thick, gelatinous, colorless polysaccharide consisting of dextran (glucose poiymer). 

C. A. Browne12 studied the cellulosio material obtained by fermentation of Louisiana sugar cane juice. His results substantiated those of A. J. Brown, and he further showed that since the nitrogen content of the membranes was only 0.2%, chitin could only be present with the cellulose membrane in traces, if at all. 

Fermenting grains with yeast produces a grain alcohol. The process also works with other biomass feedstocks. In fermentation, the yeast decomposes carbohydrates which are starches in grains, or sugar from sugar cane juice into ethyl alcohol (ethanol) and carbon dioxide. The process breaks down complex substances into simpler ones.

Hydroxy-acetic acid (glycolic acid). HOCH-COOH. is the first and simplest member of the family of hydroxycarboxylic acids. It occurs naturally as the chief acidic constituent of sugar-cane juice and also occurs in sugar beets and unripe grape juice. It is widely used as a cleaning agent for a variety of industrial applications, and also as a specialty chemical and biodegradable copolymer feedstock. 

FT-IR has been applied for determining the sucrose content of sugar cane juice [21]. In place of the more familiar transmission cell, an attenuated total reflectance (ATR) cell and clarified sugar cane juice were used to record FT-IR spectra from 800 to 1250 cm"1. In the spectra, significant wavenumbers (927.59, 997.02, 1054.87, 1116.51, and 1137.80 cm"1) have been identified for sucrose. The application of PCR has been proposed for the development of a calibration equation for sucrose content. PCR is basically a MLR applied to scores assessed by PCA. On the basis of FT-IR spectra and sucrose content, an accurate calibration equation could be obtained by the application of PCR. The root mean square difference between predicted FT-IR values and the actual values were 0.12 % (w/v) with a bias of -0.03 % (w/v). The accuracy of FT-IR for determining sugar cane sucrose is almost equal to that of NIR [25].

Behr,20 in 1877, identified aconitic acid as a constituent of sugar cane molasses while its occurrence in sugar beet products was demonstrated in 1879 by von Lippmann.21 Numerous other investigators since then have isolated aconitic acid from sugar cane juice,22-24 sugar cane molas-... 

Previously, itaconic acid was isolated from pyrolytic products of citric acid or produced by converting aconitic acid present in sugar cane juice. It is now produced on a commercial basis predominantly by direct fermentation of sugars. The biosynthesis of itaconic acid follows the metabolic sequence shown in Figure 30.15.

Both the enantiomers showed the same aroma character at the same concentration near the threshold value of ( ) sotolon moreover, there was no difference in the insect attractancy (house fly and cockroach) among the two enantiomers and the racemate of sotolon. Later, we( ) tried to analyze the aroma compound in fresh sugar cane juice and could not identify sotolon in the same fraction as that separated from cane molasses. These results suggest that sotolon was present in a racemic form prepared by mutual interaction of the constituents in sugar cane juice. 

For both the cases of methanol production and the use of vehicle-mounted gasifiers, additional investments will be associated with facilities and equipment for harvesting and transport of the biomass to the conversion sites. In the case of ethanol production from currently produced sugar cane juice or molasses, the conversion facilities would be constructed adjacent to sugar mills that already are receiving the biomass raw material. Thus, additional investments for harvesting and transport equipment would not be required. 

The use of sugar cane juice or molasses to produce an alcohol fuel may be difficult to justify economically in countries where all of the excess raw sucrose production (and molasses) can be exported at competitive world prices.
