摘要

The cane sugar industry has several co-products of immense potential value. The filter cake alone is enriched with a myriad of chemical entities such as proteins, cane wax, β - sito sterols, stigma, macro- and micro - nutrients and other organic and inorganic matter of immense commercial value. During sugar manufacture, the raw cane juice is treated in a variety of ways during the clarification process ranging from simple defecation using milk of lime to obtain moderate clarification, carbonation employing addition of CO_2 and SO2 with milk of lime or the double sulphitation process is the method of choice of most of the Indian sugar mills. The filter cake carries large quantities of organic and mineral matters including most of the proteins originally present in the cane juice. The quantity of wet filter cake obtained during process is 4% of the cane crushed. The filter cake is a rich source of an innumerable number of chemicals and can be used as unconventional raw material for commercially useful materials typified by cane wax, proteins, bio-gas, cement, cattle feed, micro- and macro- nutrients etc. The chemical composition of the filter cake in not homogeneous or fixed but varies from region to region depending upon the soil conditions, nutrients applied, process of clarification and many other factors. Also the raw juice invariably contains an appreciable quantity of coarse and colloidal wax, resins, and fats in suspension. In principle, these can bind to the settling material and affect the settling process as these being of low density, tend to rise to the top during clarification process. A part of this gets settled along with the filter cake the remaining plague the clarified juice as well as the cane sugar products. A question often raised, and certainly subject to definitive answer, is how do this additional wax effects the settling process as whether it has some role in decreasing the ICUMSA color as it can bind, though physically, with the colorants present in the clarified juice.
