Definitions

  • This invention relates to a sugar product for use in the refining process and it is to be understood that the invention does not relate to sugar products for direct consumption.
  • a very pure product is not always acceptable for certain purposes and certain buyers often specify a sugar having less than a certain polarization.
  • Raw sugar may have a polariztion of above 99 and is, therefore, unacceptable in certain circumstances.
  • the problem can and has been overcome by mixing the sugar with sufficient final molasses to bring the polarization down to the required figure, or sufiicient impurities can be left on the crystals during their manufacture.
  • the mixing step generally takes place prior to shipping.
  • a further object of the invention is to provide a sugar product which is not as liable to deterioration during transit as hitherto, and also leads to improved handling characteristics under varying climatic conditions. Still further, another object of the invention is to reduce the color of the product.
  • a still further object of the invention is to ensure that the by-products of the eventual refining process will be more valuable than the by-products obtained from a raw sugar manufactured by either of the prior art methods referred to above.
  • invert syrup is intended, in its widest sense, to mean a solution containing more than 30 percent by weight of reducing sugars.
  • the solution Preferably Patented Mar. 27, 1973 the solution should have a polarization less than that of final molasses.
  • the invert syrup can be defined as any commercially manufactured sugar solution, pure or impure, which has its reducing sugar content increased, or its polarization decreased intentionally by enzymatic or acid hydrolysis.
  • the invert syrup should, of course, have a low nonsugar content.
  • Suitable examples of invert syrups useful in the present invention are:
  • high-test molasses is used as the invert syrup.
  • the product of the present invention differs from direct consumption (soft) sugars in that it comprises large crystals whereas the latter product comprises essentially fine crystals with a large surface area.
  • Table I refers to the analysis of the basic compounds used for producing the coated sugars referred to in Tables II and III.
  • the amount of coating material is reduced by approximately 30%, thus ensuring that 0.36 and 0185 more V.H.P. sugar (i.e. crystal) is included in the final coated sugar for high and low pol sugars respectively.
  • Rendement the figure accepted by many refiners as giving an indication of the recoverable refined sugar, shows significant improvements of 0.4% to 1.0% for low and high pol sugar respectively.
