Product Description

CIL provides accredited Raw & Refined Sugar Inspection services in Roorkee, Uttarakhand, India.Sugar is tested in many ways to validate its quality. Thesetests are according to a standard set of quality parameters that are importantin demonstrating to potential buyers if the sugar meets the required standard. Sugarquality is important because it impacts the extractable sugar the amount ofsugar that can be extracted from the milling or refining processes. Before wego through each category below, it is worth noting that every client willrequire a different quality of sugar, so it is always measured on a case bycase basis. The following quality control measures consider the purity, colourand texture of the sugar.

Sugar quality, polarisation

Polarisation (pol) measures the purity of the sugar, withthe sucrose content of the sugar provided as a mass percentage. It is the mainstandard that is used to determine the quality of the sugar, and for sale to goahead there is often a polarisation specification that must be met. A sugarcrystal is very close to 100 percent pure sucrose, which is why pol is a usefulmeasure. The higher the polarisation, the purer the sugar is, the lesser thepolarisation, the more impurities are present in the sugar.

The method is simple once it is boiled down (if you willpardon the pun.) Polarisation is measured by the optical rotation of polarisedlight, (presented in the degree of Z) passing through the sugar. In laymansterms, this means measuring the amount of light refracted through the finalproduct. This makes sense when you think about the fact that molasses and otherimpurities make the sugar darker in colour, and therefore more difficult forlight to pass through.

Sugar quality ICUMSA colour measurement

Another way that sugar quality is measured is throughcolour. The term colour refers to a wide range of complex and molecularcomponents that contribute to the overall appearance of sugar. Differentcolourants respond differently to the refining process, which is why colour isan important differentiating process when refineries are purchasing raw sugarthat they want to turn into refined sugar. The processing of cane or beet canproduce different scopes in terms of colour. In fact, this was seen as soimportant that in 1897, ICUMSA (IU) was officially formed, also known as The InternationalCommission for Uniform Methods of Sugar Analysis.

This International Standards body has provided a benchmarkin terms of measuring and defining the grade and quality of the sugar, based onthe measurement of the yellowness of the sugar. The colour is dependant on theresidual molasses that are not removed in the refining process.

Sugar quality, ash

Ash refers to all the inorganic components that arenaturally present in the cane or beet. It is present in cane juice, and iscarried over in a smaller amount into raw sugar. Ash is made up of both solubleand insoluble compounds and can be determined by the conductivity of thesolution. It is quite complex chemistry, but essentially a conductance meter isused to measure the soluble, inorganic compounds present in the sugar. If thereis a high ash content in raw sugar, higher refining costs will be incurred asit will take longer to purify and there will be less yield.
