The analysis of starch in factory streams and products is tedious and time consuming. It is not surprising, therefore, that only one South African sugar mill laboratory currently analyses the factory streams for seasonal starch levels and trends. This essentially means that high starch levels are picked up only in the final raw sugar, causing an uncomfortable delay between detection and applica...

the aim of this research was optimization of refining of raw sugarcane juice using bentonite for production of natural liquid sugar or cane honey. non-sugar substances of raw sugarcan juice contains: colorants, polysaccharides, gums, proteins, etc that affect on efficiency and quality of the final product and should remove from raw sugarcane juice. gelatin is a protein which is used as an aid c...

In Brazil the sugar ethanol industry has had strong growth in the last 10 years, sometimes due to the growing sugar exportation, sometimes due to the alcohol production for automobile fuel and for exportation. Despite the growing mechanization of the raw material harvest (sugar cane), the manual work still persists. The development of this article was based in the application of the OCRA Method...

The application of ion-exclusion chromatography to desugarization of molasses has been investigated in the beet sugar industry for many years and is now being applied routinely to sucrose recovery. Recent work on the desugarization of molasses from cane processing has been carried out and a large-scale system is under construction. Ion-exclusion chromatographic processes are very efficient for ...

Dextran is one of the by-products of sour-storage rot of sugar cane (Egan, 1971). The presence of dextran in cane juice entering the mill has many deleterious effects on raw sugar processing and quality (Foster, 1969a,b; Henderson, 1971; Foster and Wright, 1969; Leonard and Richards, 1969). Hence, the removal of the polysaccharide from juice may alleviate these effects. Physico-chemical methods...

The NIRSystems 6500 spectrophotometer has been used to study analytes in bagasse, shredded cane, direct analysis of cane extracts (DAC), mixed juice, molasses and raw sugar. Analytes included pol, brix, dry solids, moisture, sucrose, glucose, fructose, invert, ethanol, colour, ash and starch. Although Near Infra Red (NIR) is a secondary technique, relying on conventional laboratory procedures f...

During the 19th century the cultivation of grass and root crops for the production of raw sugars was associated with some of the most important developments in the international economy. The burgeoning demand for cheap foodstuffs from the industrial centres of Western Europe and the United States led to an enormous increase in demand for cheap sugm along with other wicultural and industrial com...

The aim of the present experience was to evaluate the harvesting systems on the basis of trash content of raw material and the losses of millable cane, as a consequence of the harvesting operation. The analysed harvesting alternatives include differences in mechanical, semi-mechanical and manual systems and they have been evaluated in plots of 960 m2 of a same uniform sugar cane field, the test...

Emphasis over the past year has been on editorial effort to bring Chapter 44, Sugar and Sugar Products of the Official Methods of Analysis of AOAC INTERNATIONAL (OMA) to the high standards set for the 17th Edition of the compendium. In addition, 2 method studies were reported and subjected to peer review, respectively, dealing with detection of adulteration of maple syrup by beet or cane sugar ...

The South African sugar industry has recently moved from a cane payment scheme based on the sucrose content of cane to one based upon the concept of recoverable value (RV), which is itself a modification of the estimated recoverable crystal (ERC) quantity as originally presented by van Hengel (1974). While the definitions of ERC and RV attempt to discount the effect of cane quality on factory p...
