A Liquid Starch Sugar Purification System Capable of Alkali Sterilization of the Entire Service Tower

Abstract

Various methods using ion exchange resins are known for the purification of liquid starch sugar solutions that are used as sweeteners in many soft beverages. Ion exchange resin used in the purification process is generally maintained at 30 to 40°C, considering the heat resistance of the ion exchange resin and the inhibition of unwanted isomerization of liquid starch sugar solutions and other unwanted side reactions. However, there is concern about microbial contamination within the refinery equipment unit, even if the afore-mentioned temperature is considered appropriate. The liquid starch sugar purification system mentioned in this paper incorporates antibacterial measures into the conventional ion exchange purification process through alkali sterilization of the entire service tower that supplies the liquid starch sugar.
