 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Bacteria in Sugar Cane Juice From the Cane Sugar Processing in Thailand) ผู้เขียน: นายวิวัฒน์ แดงสุภา, อาจารย์ ,  Boonsong Saeng-on สื่อสิ่งพิมพ์:pdf AbstractThe study of the different stages of sugar cane juice collected from 9 sugar cane factories in the middle and the eastern part of Thailand, on the general properties such as temperature, pH, sugar content and total acid content; and especially emphasized on the number and species of bacteria which showed an important role in decomposing the sugar content in the juices revealed that the Streptococcus sp. was the major population and showed the highest activity in decomposing the sucrose content in the juice. Lactobacillus fermentum, Leuconostoc mesenteroides and Lactobacillus cellobiosus were also found some predominant and as well decomposing activity in the juice. The bacteria in the juice not only decreased the sucrose content about 0.2 - 0.6 percent but were also able to produce acids and dextran, a slimy substance that could cause a problem in the processing of a sugar factories. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Quaternary Ammonium Compounds Chemical Control of Bacteria in Sugar Cane Juice by Using Quaternary Ammonium Compounds ) ผู้เขียน:Boonsong Saeng-on, นายวิวัฒน์ แดงสุภา, อาจารย์ สื่อสิ่งพิมพ์:pdf AbstractIn the 1982 - 1983 season, it was found that the sugar factories used 4 kinds of chemicals to control microorganism in sugarcane juice. They have the trade names of Maquat-1416, Hexemine X-100, CMA and Lutensit-KIC. All these chemicals belong to the group of quaternary ammonium compound (QAC) and have been approximately used at the concentration of 5 ppm. The effect of 3 quaternary ammonium compounds, Maquat-1416, CMA and Hexemine X-100 were tested. All these compounds were inhibitory at minimum concentration of 10 ppm to the following bacteria : Leuconostoc mesenteroides, Streptococcus sp., Lacto bacillus cello biosus, Bacillus sub tilis, Lactobacillus Fermentum, Erwinia herbicola and Proteus sp. Pseudomonas sp. and Klebsiella sp. were resistant to these chemicals. A study on the bactericidal property of these compounds at concentration of 10 ppm for 20 minutes was also undertaken. It was found that CMA could only inhibit the bacteria but not kill them, while Maquat-1416 could kill many bacterial species. Hexemine X-100 could inhibit most of the test bacteria and could kill just a few. The study indicated that the increase in the concentration of QAC to 10 ppm could control the bacteria in sugarcane juice and could reduce the rate of detrimental sucrose effectively. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : The Use of Diatomite to Remove Color and Turbidity in Sugar Industry) ผู้เขียน:ดร.ลัดดา มีศุข, รองศาสตราจารย์, อรรถวรรณ เบญจมาศ, Cherdsak Utha-aroon สื่อสิ่งพิมพ์:pdf AbstractDiatomite is a pale colored, light weight rock composed mostly of silica microfossil of algae, being known as diatoms. The experiments of using natural diatomite from Lampang, central Thailand to remove color and turbidity in sugar cane juice processed in a sugar factory gave satisfactory results. The color in ICUMSA (International Commission for Uniform Methods of Sugar Analysis) and turbidity of the treated juice were better, i.e., lower than that of the clarified juice from the industrial process lines, while sugar content tended to be higher. The two most appropriate conditions were obtained; when diatomite was used not more than 4% by weight of the juice or 2% diatomite followed by 1 ppm anionic polymer. Analyses of properties of the treated juice and physical and chemical properties of diatomite revealed physical and chemical adsorption properties of diatomite. |
