  • The recent much attention has been given to weight gain of the population and its consequences on the occurrence of diet-related diseases in developed countries. Sugar is considered to be the main culprit of these phenomena. Food manufacturers attempt to provide the consumer with reduced energy products with non-nutritional sugars. Some studies also showed that consumers preferred foods prepared with natural additives rather than chemical ones, due to health reasons. This article reviews issues related to sugar alternatives, as well as their use, health benefits and risks.

  • The heat of hydration can be reduced through the use of retarding agents. Typical retarding agents include sugar and glucose. However, these significantly delay the setting of cement paste. For the efficient use of sugar and glucose for mass concrete construction, it is necessary to develop a technique that can provide a setting behavior equivalent to that of plain concrete. In this work, the temperature rise of cement paste was monitored with the addition of various retarders including sugar and glucose. Hydrated cement powder was made with a water to cement ratio of 5 in order to accelerate the retarded cement pastes. It was found that the addition of hydrated cement powder in retarded pastes reduced the maximum temperature of cement paste. The use of hydrated cement powder could also successfully reduce the time to reach the maximum temperature.

  • Effects of various sub-ingredients (hot pepper, garlic, ginger, green onion, leek, salted and fermented anchovy juice, and sugar) on the sensory quality of Korean cabbage kimchi were investigated. Sixteen sensory attributes were selected and their intensities evaluated by 20 panelists. The kimchi had an unbarmonized taste and unpleasant flavor when fermented with individual sub-ingredients, but had a well harmonized taste when fermented with all sub-ingredients. Hot pepper, ginger and garlic contributed to reduction of the unpleasatnt taste and moldy odor. The strong garlic flavor was reduced by adding green onion and leek. Salted and fermented anchovy juice gave a palatable taste, and the overall taste was improved by adding sugar. All sub-ingredients except sugar reduced the sour tasts.

  • This study intended to compare the effects of the sugar-Omija extract tea (SO) and LuoHanGuo-Omija extract tea (LO) to blood glucose levels and metabolism among streptozotocin (STZ)-induced diabetic mice and to prove the positive effects of LuoHanGuo extract as a sugar substitute. According to the results, the rate of blood glucose increase and the blood glucose level was reduced, and the weight was increased. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride, low density lipoprotein cholesterol, and total cholesterol was decreased, and albumin, total protein, and high density lipoprotein cholesterol (HDL-C) was increased in the STZ/LO group as compared to the STZ group. Compared to the STZ/SO group, the rate of blood glucose increase and glucose tolerance was decreased. AST, ALT, and total cholesterol was decreased, and HDL-C level was high. In conclusion, the LO displayed hypoglycemic effect, prevented weight loss caused by diabetes, recovered liver function, and improved lipid metabolism. In addition, such positive effects were obviously shown during comparison with the experimental group treated with the SO. Therefore, the LO were considered as favorable food supplements that can be safely taken by persons with diabetes, obesity, hypertension, and heart disease; they have to control their sugar intake as well as their diet.

  • To investigate the effects of reduction of leaf processing factories on the uniformity of processed leaf quality, the contents and their C.V.(Coefficient of Variation) of chemical constituents of flue-cured leaf tobacco produced from 1997 to 2001 and processed at various factories were analysed. The average leaf chemical contents of 12 grades for 5 years ranged as follows ; nicotine 2.00∼0.85%. total sugar 10.7∼16.9%, total nitrogen 2.36∼2.78%, crude ash 14.6∼15.6% and chlorine 0.50∼0.75%. The variations of chemical contents among crop years was higher in total sugar content while lower in crude ash content. The C.V. of chemical content in same grade leaves was higher in chlorine content while lower in total nitrogen and crude ash contents, and the ratio of C.V. among processing factories/C.V. in total population was higher in total sugar content while lower in crude ash content. When the leaves were processed at one factory, the deviations of chemical contents reduced considerably. Particularly, the decreasing effect of deviation was higher in total sugar content.

  • Anti-diabetic effect was observed with Thespesia lampas Dalz & Gibs (Family: Malvaceae) when given as a root extract in normal as well as alloxan induced diabetic rats. The effects, however, were more pronounced in diabetic animals in which administration of plant extract for 15 days after alloxan induced diabetes, significantly reduced blood glucose levels. After alloxan induced diabetes it was observed that both standard drug (glibenclamide) and aqueous extract of Thespesia lampas were significantly superior to control in reducing blood sugar on long term treatment (15 days). The aqueous extract of T. lampas (300 and 600 mg/kg) reduced the blood glucose levels from $349.2{\pm}7.2$ to $120.7{\pm}4.6$ and $346.3{\pm}3.4$ to $101.8{\pm}6.3$, respectively. The data suggested that T. lampas could be of beneficial in diabetes mellitus in controlling blood sugar. The present investigation established pharmacological evidence to support the folklore claim as an anti-diabetic.

  • Effects of various environmental factors on cell size index(FCW/DCW) in Thalictrum rugosum. Lithospermum erythrorhizon and Taxus cuspidata plant cell suspension cultures were investigated. Time course change of cell size index were also observed. In batch cultures, FCW/DCW increased according to the decrease of sugar concentration. For short-term experiment within 24 hr, FCW/DCW value could be reduced significantly by increasing sugar concentration. When an osmoticum such as mannitol was added, FCW/DCW converged to a low value. Therefore, it was confirmed that osmolality of the medium was important in determining cell size or water content of the cells. Inorganic salts or treatment with organic solvent also exhibited some effect on the cell size index. However, pH and centrifugal force did not show any influences. On the other hand, it was found that the addition of Pluronic F-68 reduced FCW/DCW. By combining these results effectively, it may be possible to increase the cell concentration in high density culture to a higher extent.

  • The performance of ultrafiltration (UF) membranes with molecular weight cut off (MWCO) of 1000 and 3500 Da in clarifying sugar cane juice was investigated, as well as the performance of a nanofiltration (NF) membrane with MWCO of 200 Da and a reverse osmosis (RO) membrane in concentrating sugar cane juice. For both cases the sugar cane juice had been limed and partially clarified. The UF membranes were found to be effective at clarifying the sugar cane juice in terms of purity rise and reduction in turbidity, colour, starch and protein. A purity rise of approximately 6 was achieved by both UF membranes at trans-membrane pressures (TMP) from 15 to 25 bar. However, Brix reduction in the permeate was between 14.5 and 41.85% and 12.11 and 26.52% for 1000 Da and 3500 Da membranes respectively. For the 200 Da and RO membranes the Brix in the concentrate was increased from 7.65 to 12.3 after 3 hours of operation for the 200 Da membrane at a TMP of 10 bar, whilst the Brix in the concentrate was increased from 15.65 to 27.6 after 3 hours of operation for the RO membrane at a TMP of 35 bar. Overall, UF membranes were found to be unsuitable for clarification of sugar cane juice since significant amount of Brix is reduced in the permeate, whilst RO membranes were found to be effective for concentration of sugar cane juice.
