Hydrolysis of inulin was investigated employing various commercially available resin catalysts for the production of high grade fructose syrup. The particle size and porosity of the resin significantly affected the distribution of the products, indicating that the intraparticle diffusion of reactants controls thc selectivity as well as the reaction rate. To confirm the effect of the intraparticle diffusion, two different types of resin catalysts were prepared: the one having sulfonic acid group distributed uniformly throughout genular microparticles (A-type) and the other having sulfonic acid group located mainly at the exterior surface of genular microparticles (E-type). The results were found that the reaction rate and the selectivity of the E-type catalyst were higher than those of the A-type catalyst.

This study examined the effects of various oils used in the preparation of goami baked Yackwa dough on the quality characteristics of goami baked Yackwa. To determine the optimal amount of oil for goami powder Yackwa dough, the hardness and moisture contents of both the flour and goami powder dough were measured. Dough hardness was the highest in flour Yackwa while moisture contents was the highest in goami Yackwa. Baked weight and dip syrup weight were heavier in flour. Hardness, a-values, and b-values were the highest in flour Yackwa, whereas moisture contents and L-values was the highest in goami Yackwa. In a sensory evaluation, overall preference was the highest for goami Yackwa and flour Yackwa made with 10% oil.

The transformation kinetics between polymorphs of sulpiride and the effect of additives on the transformation kinetics were studied. The results could be summarized as follows. 1. Transformation kinetics of the polymorph form I to form II in water suspenion was first order type and transformation rate constant at $25^{\circ}C$ is $2.61{\times}10^{-2}min^{-1}$, the half life of form I was about 27 minutes and the activation energy for transformation was 21.35 Kcal/mole. 2. Glycerine and coloring agents increased the rate of transformation., In the case of polysorbate 80, the rate constant increased in proportion to the concentration of polyserbate 80. Simple syrup showed no effect 3n transformation kinetics.

The study was made for storage test of Yackwa, which is typical cookies of Korea and contain about 20% of vegetable oil. As the result of investigation the variation of POV and AV of oil contained in Yackwa which was stored in packed or unpacked state for 60 days, at the temperature of $5^{circ}C$ or $30^{circ}C$ respectively, it was found that the Yackwa of AV, about 2, and POV, about 20, was considerably stable for storage. This result of the good storage condition of Yackwa containing a considerable amounts of Vagetable oil which proceed the rancidity, is derived from the formed film on the surface of Yackwa by the sugar syrup afterwards.

Zingiber officinale is a spice which is having a strong historical medicinal background and used by different systems of medicine for various ailments. It is also used to maintain the characteristic sharpness and tangy essence of food and beverages and used in carbonated drinks, as a conserve in sugar syrup. Ginger considered as an incredible drug for inflammation, gastrointestinal problems, pain and sexual problems since centuries. There are many studies carried out in recent years, which proves that the active constituents of ginger shows a variety of pharmacological effects like antiemetic, hepatoprotective, anti hyperlipidemic and antibacterial. The most momentous among all the nutraceutical aspects of ginger are its positive control on gastrointestinal tract including digestive stimulant action, anticancer effect and anti-inflammatory effect.

The concerns over obesity and obesity-related health problems are increasing as many consumers relate these health problems with sugar. The demand for sugar reduction is also rising and regulatory movement by governments including Korea is driven to reflect such demand. For the past decades, there have been diverse development and marketing of various sweeteners to substitute sucrose and high fructose corn syrup. Low caloric alternative sweeteners can be divided into high intensity sweeteners that have greater sweetness potency compared to sucrose, and low intensity sweeteners such as polyols, oligosaccharides and rare sugars that have less sweetness potency. This paper discusses representative low caloric alternative sweeteners, their market and trend.

The starch industry in Korea had been based on sweet potato and potato for long time to produce starches which were used for mainly starch noodle such as cellophane noodle. Because of the poor storage stability, high price, and fluctuation of production by year and year of potatoes, the raw material for the production of starch had been changed to corn in 1970s. Along with this, the mass production system had been established, which enabled the production of various starch-related products including modified starches for food, textile, paper, and other industrial uses, starch sweetners, high fructose corn syrup, and gelatinized starch. In this paper, a brief background of corn industry in Korea has been described. The production of starch from corn has been emphasized and the future of corn industry in relation with GMO has been suggested.

The rising prevalence of obesity and diabetes is a significant health concern both in globally and is now regarded as a worldwide epidemic. Added sugars like sucrose and high-fructose corn syrup (HFCS) are a major concern due to their link with an increased incidence of diet-induced obesity and diabetes. The purpose of this review is to provide insight into the effects of natural sweeteners as alternatives to sucrose and HFCS, which are known to have negative impacts on metabolic diseases and to promote further research on sugar consumption with a focus on improving metabolic health. The collective evidences suggest that natural alternative sweeteners have positive impacts on various markers associated with obesity and diabetes, including body weight gain, hepatic fat accumulation, abnormal blood glucose or lipid homeostasis, and insulin resistance. Taken together, natural alternative sweeteners can be useful substitutes to decrease the risk of obesity and diabetes compared with sucrose and HFCS.

The prevalence of obesity has been increasing worldwide. Several dietary treatments have been suggested to control weight, and recent guidelines recommend individualizing the composition of macronutrients. Carbohydrates are the most important nutrients in meals, and carbohydrate restriction is a dietary strategy that promotes weight loss. A low-carbohydrate diet is effective for short-term weight loss and can help improve glycated hemoglobin, systolic blood pressure, diastolic blood pressure, and triglyceride levels; however, the long-term effects and safety of this diet remains doubtful. In the short term, there is a risk of gastrointestinal symptoms such as vomiting, diarrhea, constipation, and gastroesophageal reflux, and type 1 diabetes patients are at risk of severe hypoglycemia, while in the long term, it can lead to malnutrition and decreased exercise capacity. Thus, rather than limiting the intake of carbohydrates, it is important to limit the intake of refined grains, sugar, honey, syrup, and sweetened beverages while maintaining the planned carbohydrate intake rate and improving meal quality.
