  • Pakistan being the 6$^{th}$ largest sugar producer has over 75 sugar mills with annual production capacity of about 2.4 million tons during 1996-97. The contribution of Sindh with 27 sugar mills is recorded over 50% of the total sugar production. The majority of the mills in Pakistan use the Defecation-Remelt-Phosphitation (DRP; 24 mills), Defecation-Remelt-Carbonation (DRC; 21 mills) and Defecation-Remelt Carbonation and Sulphitation (DRCS; 11 mills) process. Seven of the 75 sugar mills in Pakistan also produce industrial alcohol from molasses, a by- product of sugar manufacturing process. These sugar industries also produce fly ash, which have been found to contain unburned carbon and reach as far as four-kilo meter area with the wind direction, threatening the community health of people living around, besides posing other aesthetic problems. The untreated wastewater, in many cases, finds its way to open surface drains causing serious threat to livestock, flora and fauna. One study showed that fly ash emitted from the chimneys contain particle size ranging from 38 ${\mu}{\textrm}{m}$ to 1000 ${\mu}{\textrm}{m}$. About 50 per cent of each fly ash samples were above 300 ${\mu}{\textrm}{m}$ in size and were mostly unburned Carbon particles, which produced 85% weight loss on burning in air atmosphere at 1000${\mu}{\textrm}{m}$. This fly ash (mostly carbon) was the main cause of many health and aesthetic problems in the sugar mill vicinity. The environmental challenge for the local sugar mills is associated with liquid waste gaseous emission and solid waste. This paper discusses various waste recycling technologies and practices in sugar industries of Pakistan. The application of EM technology and Biogas technology has proved very successful in reusing the sugar industry wastewater and mud, which otherwise were going waste.

  • The objective of this study is to analyze the characteristics of persons with a high sugar-intake ratio (%E) and factors affecting sugar-intake ratio with the Korea National Health and Nutrition Examination Survey ($6^{th}$ KNHANES). The sugar-intake ratio is the calories of sugar from processed food divided by the daily total intake of calories. In this research we used two statistical methods, the cluster analysis and one-way analysis of variance (ANOVA). Cluster analysis was used to classify groups of sugar-intake ratios. For analysis of factors affecting the sugar-intake ratio, we applied the ANOVA. Korean have about a 3.89% sugar-intake ratio from processed food per day. The demographic characteristics of people with higher sugar-intake ratios were found to be more women than men, younger men with less education, more people in the household, smaller height, weight waistline and body mass index (BMI). Also office worker, lower drinking frequency, not getting a hypertension, diabetes, hyperlipidemia, lower breakfast and dinnner frequency, not experiencing nutritional education, and not using nutritional labeling. For reducing intake sugar in what are called health-hazardable nutrients in the food sanitation act, it is necessary to educate the people with high sugar ratio who were identified in this study.

  • As recently many studies on the relationship between excessive sugar intake and chronic disease have been reported across the world, more attention to sugar intake has been paid. Sugars, called simple sugars, is a kind of carbohydrate and sum of monosaccharides and disaccharides. Sugars that are particularly related to health are added sugars or free sugars, which are added to food by processing or cooking. It is generally not to give satiety and increases energy density without other nutrients. Especially, the major food source of added sugar is sugar-sweetened beverages(SSBs), from which sugars are closely linked with health outcome. The total sugar intake in Korea is 61.4 g per day and it is almost half of those in the western countries such as the U.S. or Australia and it is within the recommendation level by the Dietary Reference Intakes for Koreans. However, when it is classified by age groups or food sources, sugar intake in adolescents and young adults are high and the sugar from processed foods is also high that would lead to high intake levels of added sugar. Particularly, the frequency of SSBs, the major food source of added sugar, is the highest among 20's. While the studies of excessive sugar intake with chronic diseases including obesity, type 2 diabetes, metabolic disease, cardiovascular disease reported in the Western populations, those in the Korean populations have just started. Given our dietary practice is very different from those in the western population, more prospective studies would be necessary to evaluate sugar intake by type or food source exactly and examine its relationship with chronic diseases in the Korean population.

  • The study investigated the pH, acidity, soluble solids, total sugar, polyphenol, flavonoid, anthocyanin content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, and color of kombucha with a variety of added fruit peels during the fermentation process. Pear, grape, plum, orange, apple, and golden kiwi peels were added during fermentation. The pH showed a decrease, while an increase in acidity was observed. An increase in soluble solids, which was higher in most experimental groups than the control group, was also observed. A decrease in total sugar was observed over time. However, an increase was observed in reducing sugar. On Day 0, higher total sugar and reducing sugar were detected in the peel addition group compared with the control group. The antioxidant capacity of polyphenol, flavonoid, anthocyanins, and DPPH radicals scavenging increased with fermentation and was higher in all addition groups, except for pear, compared with the control group. Except for grapes and plums containing high levels of anthocyanins, an increase in the L-value was observed over time, and an increase in the a-value of grapes and plums was also observed (p<0.05). The possible utilization of inedible fruit peel in kombucha was shown. Applying inedible fruit peels to kombucha is proposed to increase antioxidant content and modulate color and pH.

  • Response surface methodology was used to investigate the quality of clarified mixed apple and carrot juices using ultrafitration. Apple and carrot juices were blended at the ratio of 1:3, 1:1, and 3:1. A three-variable, three-level central composite design was employed where the independent variables were the blend ratio, temperature and average transmembrane pressure (ATP). With increasing temperature and pressure, flux linearly increased regardless of blending ratio. Blend juice with 75% apple showed the highest soluble sugar and total sugar content in apple and carrot blend juices. Soluble solid contents were more affected by blending ratio than temperature and ATP. Total sugar contents were greatly affected by temperature; increasing temperature led to higher total sugar content up to $25^{\circ}C$. Higher carrot ratio led to higher vitamin C content. In general, higher acidity was achieved by higher apple content and acidity was increased with increasing temperature. Turbidity increased for all samples as APT increased, with the blending ratio of 1:1 (apple:carrot) showing the highest turbidity. Viscosity was greatly changed in the blending ratio of 3:1 (apple:carrot) juice. The polynomial models developed by RSM were satisfactory to describe the relationships between the studied factors and the responses. Analytical optimization gave $flux=0.216\;L/m^2.h$, soluble $solids=10.39^{\circ}Brix$, total sugar=71.32 mg/mL, vitamin C=315.18 mg%, acidity=7.78 mL, turbidity=0.017, and viscosity=1.44 cp, when using a $temperature=44.97^{\circ}C$, ATP=113.57 kPa, and blend ratio=28.50%.

  • It is a well known fact that obesity is an important cause of cardiovascular disease, emphasized by many studies. Recently, cardiovascular diseaase has been found to correlate not only to the extent of obesity, but also the fat distribution of the individual; especially, focusing on obesity of the abdomen. Unfortunately, the proposed indices for abdominal obesity are numerous, and the results vary according to the index chosen. Three-hundred and twelve bus drivers in November, 1995, were chosen as subjects of this study. The author chose to measure serum lipid levels, fasting blood sugar levels and blood pressure, that are thought to be important risk factors of cardiovascular diseases. Obesity indices were calculated using anthropometric measurements. We were able to evaluate the significance of obesity indices by examining correlations between these indices and the risk factors of cardiovascular disease. The results obtained were as follows: 1. The abdominal obesity indices and risk factors of cardiovascular disease, the levels of total cholesterol in the serum, fasting blood sugar levels, and diastolic blood pressure, increased significantly according to age. 2. There was a significant difference in the abdominal obesity indices according to drinking and smoking habits controlled for age. Among the risk factors of cardiovascular disease, triglyceride and diastolic pressures had significant differences according to the presence or absence of a drinking history controlled for age. 3. Although all obesity indices showed significant correlations, the weakest correlation was between BMI and abdominal diameter index and the strongest correlation was between sagittal diameter and sagittal diameter matched for height. 4. There was a negative correlation between HDL-cholesterol and obesity indices. The weakest correlation was between fasting blood sugar levels and both SD and SDH showed correlations with the risk factors. 5. There was a significant correlation between SD and total cholesterol in the serum and fasting blood sugars controlled for age, drinking, and BMI. 6. After categorizing the subjects into 2 separate age groups at the 40 year mark, in the less than 40 you old age group, controlled for drinking and BMI, the results of comparitive studies have shown correlations between total cholesterol serum levels and waist-hip ratio, conicity-index, and SD. There were correlations between fasting blood sugar levels and SD, ADI, and SDH. There were no correlations between obesity indices and both total cholesterol serum levels and fasting blood sugar levels in the greater than 40 year old age group. There were significant correlations between abdominal obesity indices and total serum cholesterol or fasting blood sugar levels in the less than 40 year old age group, but no correlations in the age group over 40. These correlated factors between abdominal obesity and cardiovascular disease are assumed to exist in Korea as well. Furthermore, in this study a high correlation was found between SD, SDH and the risk factors of cardiovascular disease. Even when controlled for age, drinking, smoking, and BMI, the correlations between risk factors of cardiovascular disease and these indices exist. Therefore, the obesity indices, SD and SDH may prove to be important prognostic indicators or risk factors of cardiovascular disease.
