There are always strong incentives for Process Management to achieve high levels of technical performance in a sugar factory. This is particularly so in the South African sugar industry where the ‘Division of Proceeds’ system accentuates these incentives. The primary route to achieving good technical performance is usually close control of process operations, guided by detailed measures of fact...

A solution to the problem of eliminating the use of toxic reagents in the laboratories of the South African sugar industry has been sought for some time. This paper contains the results of an investigation to replace basic lead acetate as a clarification agent in the determination of pol by substituting it with a mixture of aluminium chloride and calcium hydroxide. This mixture achieves good cl...

We report the engineering of Lactococcus lactis for the efficient conversion of sugar into diacetyl by combining NADH-oxidase overproduction and alpha-acetolactate decarboxylase inactivation. Eighty percent of the carbon flux was found to be rerouted via alpha-acetolactate to the production of diacetyl by preloading the cells with NADH-oxidase before their use as a cell factory.

Two types of tracer are described added and natural. The former is useful for following physical and the latter for monitoring chemical pathways in the sugar factory. Some analytical advantages and limitations of using lithium for the first application and chloride or potassium for the second are highlighted.

objective: many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. thus agronomic package must be always modified. this sutdy was laid out for evaluation of changes in carbohydrates and sugar yield in sugar beet (beta vulgaris l.) under different biofertilizers and irrigation closed time at dorud region of iran, during 2013. methods: the experimental design...

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...

In the light of increasing public pressure to minimise environmental pollution, green cane harvesting will probably soon become the norm worldwide. The effects of delivering and crushing green cane, which contains all of the associated extraneous matter, on the cost of production and the quality of sugar are well known. In consequence of these effects the different options for dry cleaning the ...

The use of different organic carbon sources in the denitrification of wastewater containing 2500 mg nitrates/L in a SBR was studied. Three alternative sources of carbon were tested: wastewater from a sweet factory, a residue from a soft drinks factory and a residue from a dairy plant. The first two are sugar-rich, whereas the third presents a high content in lactic acid. Maximum specific denitr...
