Abstract

Sugar production in the Philippines is one of the largest in the production industry. Sugar as a commodity is very versatile and very marketable.Its application ranges from simple coffee sugar in Filipino homes to sweeteners in large beverage companies in the country. The scope of sugar's applicability renders it to be one of the most economically significant products of the country.The importance of sugar to Filipinos led to be the advancement in research and innovation in terms of the production capacity and quality. The university of the Philippines Los Baños responds to such developments and has gradually developed students by allowing them to participate in a practicum exercise done at the Central Azucarera Don Pedro, Inc. (CADPI), Nasugbu Batangas, Philippines. CADPI uses canes from all over Batangas and extracts its juice through mill tandems in series. The watering system utilizes the compounded Imbibition process where water is recirculated as juice to allow wetting of the fibers. The extracted juice enters clarification with lime before it is concentrated in a quintuble evaporation process. The Boiling House department CADPI receives the concentrated juice and further concentrates it through a vacuum pan system to initialize the crystal formation. Once the end solution enters crustallization, the crystals will start to grow as more distinct particles and may then be centrifuged to separate the sugars from the molasses. The molasses is reused as distillation substrates for the production of beer or ethanol. The Raw sugar enters the refinery department where it is "cleaned thoroughly through a similar system of sugar production in the raw sugar production. However, the clarification of the sugar is intensified by the introduction of the Ion-exchange Resin decolorization using the serial adsorption on polyacrylic then polystyrenic resins. The resins chemically adsorb the colorants onto its surface by attracting it with ionic bonds. These bonds however do not lead to the formation of a new species. The special topic of this paper focuses on the adsorptive and decolorizing power of IER on the Brown II Liquor by laboratory analyses. Comparison on the performance of the fresh resins versus the one-year old resins is also tackled by this publication. The laboratory results show very good color removal values with an average of 94.5472%. The one-year old resin, o the other hand, proved to be no longer useful as it increases the color when Brown II is decolorized to Fine Liquor.
