The objective of this study was to evaluate the quality-based characteristics of Prunus mume fruit syrup, which is manufactured with various sugared sweeteners for suggestion of suitable alternative sweetener. Sweetener such as sucrose (MHP1), crystalline fructose (MHP2) and liquid fructo-oligosaccharide (MHP3) are used to manufacture Prunus mume fruit syrup. The sugar content of MHP1, MHP2 and MHP3 showed 53, 54 and $36^{\circ}Brix$, respectively. The total organic acid content of MHP1, MHP2 and MHP3 was 2.22, 3.07 and 3.71%. The total free sugar content of MHP1, MHP2 and MHP3 was 54.39, 47.52% and 31.62%, respectively. The appearance of MHP1 and MHP2 remained unchanged for the entire period but MHP3 had molded since the first week. This was as a result of the low total free sugar content in MHP3 sugared with liquid fructo-oligosaccharide compared to MHP1 and MHP2 sugared with solid sucrose and fructose. The sensory characteristics of MHP2 manufactured with crystalline fructose indicated an above average quality, indicating that it is difficult to manufacture Prunus mume fruit syrup using liquid sugar. It is suggested that crystalline fructose characterized solid form and lower glycemic index than sucrose be useful to manufacture Prunus mume fruit syrup as alternative sweetener.

Objectives: Several studies have investigated the effects of serum uric acid (SUA) levels on chronic kidney disease (CKD), with discrepant results. The effect of SUA levels on CKD development was studied in the Korean rural population. Methods: A total of 9695 participants aged ≥40 years were recruited from 3 rural communities in Korea between 2005 and 2009. Of those participants, 5577 who participated in the follow-up and did not have cerebrovascular disease, myocardial infarction, cancer, or CKD at baseline were studied. The participants, of whom 2133 were men and 3444 were women, were grouped into 5 categories according to their quintile of SUA levels. An estimated glomerular filtration rate of <60 mL/min/1.73 m2 at the time of follow-up was considered to indicate newly developed CKD. The effects of SUA levels on CKD development after adjusting for potential confounders were assessed using Cox proportional hazard models. Results: Among the 5577 participants, 9.4 and 11.0% of men and women developed CKD. The hazard ratio (HR) of CKD was higher in the highest quintile of SUA levels than in the third quintile in men (adjusted HR, 1.60; 95% confidence interval [CI], 1.02 to 2.51) and women (adjusted HR, 1.56; 95% CI, 1.14 to 2.15). Furthermore, CKD development was also more common in the lowest quintile of SUA levels than in the third quintile in men (adjusted HR, 1.83; 95% CI, 1.15 to 2.90). The effect of SUA was consistent in younger, obese, and hypertensive men. Conclusions: Both high and low SUA levels were risk factors for CKD development in rural Korean men, while only high levels were a risk factor in their women counterparts.
