  • Dietary fiber naturally present in various sources of cereals, legumes, fruits and vegetables plays a physiological role in human health, such as lowering cholesterol and blood pressure, improving blood glucose control in diabetes, helping with weight loss and management, and reducing cancer risk. In addition, dietary fibers have has been added as a functional food ingredient to food products to provide water-holding capacity, viscosity, gel-forming ability, and fat-binding capacity to food products. These beneficial characteristics of dietary fiber components can improve the image of meat products to be healthy and functional food products. This article reviews the concept and current definition of dietary fibers in food products along with their health benefits and functional characteristics. Dietary fibers from different sources like cereals, legumes, fruits, and vegetables and soluble dietary fibers have been applied as functional ingredients to various types of meat products, such as beef patties, ground beef and pork, pork and chicken sausages, meatballs, and jerky etc. Based on the application of dietary fibers to different types of meat products, possible future characteristics in selecting appropriate dietary fiber ingredients and their proper incorporation are explored to develop and produce healthy and functional meat products with high dietary fiber contents.

  • Brown rice with a giant embryo (GE) was observed on the quality parameters of the enlargement of embryo, nutritional components, and physical properties, in comparison to normal embryo brown rice (NE). Also, the effects of germination on the quality parameters were examined. GE embryo was approximately 2.68 times larger than of NE rice. Total free sugars were significantly higher in GE rice (71.96 vs. 41.17 mg/100 g), and germinated rice increased in fructose, but decreased in sucrose and maltose. No significant difference in mineral contents was found in GE and NE rice and their germinated rice, whereas a significant increment was observed on reducing sugars and gamma-amino butyric acid (GABA) contents in GE rice. The lower water absorption index (WAI) of GE rice resulted in relatively lower pasting viscosity, whereas the increased WSI in germinated rice might be attributable to the significant increment of soluble components in GE rice.

  • The antioxidant activity of various solvent extracts from Jeju camellia mistletoe (Korthalsella japonica (Thunb.) Engl.) was investigated using various in vitro assays as the 1,1-diphenyl-2-picrylhydrazyl radical scavenging, ferrous ion chelating and reducing power assays. Methanol and ethanol extracts showed the most potent antioxidant activity in all assays tested followed by water extract. The inhibitory effect of the Jeju camellia mistletoe extracts on pancreatic lipase and $\acute{a}$-glucosidase was also evaluated and the results showed that methanol and ethanol extracts markedly reduced both enzyme activities. Therefore, the methanol and ethanol extracts of Jeju camellia mistletoe is definitely worthy of further investigation for these beneficial effects on nutraceutical medicine.

  • Crude protein (CP) content of mechanically ground rice straw into small particles by an electric grinder and reducing value (RV) and soluble protein (SP) in the culture filtrate were lower than that of the chopped straw into $5{\sim}6\;cm$ lengths when both ground and chopped straws were fermented with Aspergillus ochraceus, A. terreus or Trichoderma koningii, at steady conditions. The reduction rate of RV, SP and CP was 22.2, 2.4, 7.3%; 9.1, 4.9, 8.5% or 0.0, 0.0, 3.6% for the three fungi, respectively. Chemical pretreatment of straw by soaking in $NH_{4}OH$ for a day caused significant increase in CP of the fermented straw than the other alkali and acidic pretreatments. Gamma irradiation pretreatment of dry and wet straw with water, specially at higher doses, 100, 200 or 500 kGy, caused significant increase in RV and SP as CP in the fermented straw by any of these fungi. Chemical-physical combination pretreatment of rice straw reduced the applied dose of gamma irradiation required for increasing fermentable ability of fungi from 500 kGy to 10 kGy with approximately the same results. Significant increases in RV and SP of fermented straw generally occurred as the dose of gamma irradiation for pretreated straw, which combined with $NH_{4}OH$, gradually rose. Whereas, the increase percentage in CP of fermented straw that was pretreated by $NH_{4}OH-10\;kGy$ was 12.4%, 15.4% or 8.6% for A. ochraceus, A. terreus or T. koningii, respectively.

  • The water extracts of root, stem, and leaf from Korean indigenous Acanthopanax divaritacus were examined for their suppressive effects against allergic inflammations such as lipoxygenase activity, ${\beta}-hexosaminidase$ release, inflammatory cytokine production, and serum IgE level. The root extract inhibited the release of ${\beta}-hexosaminidase$, a degranulation marker, from rat basophilic leukemia cells (RBL-2H3) much more potently than the stem and leaf extracts. The root extract also significantly reduced the expression of $TNF-{\alpha}\;and\;IL-1{\beta}$ in the RBL-2H3 cells challenged with antigen. Moreover, there was a significant fall in the serum IgE level by the treatment of the root extract. Taken together, the root extract could be the most potent inhibitor of allergic inflammation, suppressing ${\beta}-hexosaminidase$ release and inflammatory cytokine expression, as well as reducing the rise of serum IgE level.

  • Landscape space can and should play as a multi-functional agent : healing contaminated soil, reducing natural hazards, supporting living things, making comfortable environment for human, and appealing to human aesthetics, etc. This article aims to show the possibility and role of landscape space as such agent. In landscape design for National Marine Biology Resource Institute, distributed rain water treatment system and rain gardens are introduced to replace a mono-functioning large detention pond which was suggested by disaster impact assesment. Phytoremediation and vegetation filtering system with muti-cell wetlands are also adapted to heal the contaminated soil. This kind of landscape as a 'living machine' which can play as an operational control utility of multi-environment and thus can be combined effectively into green infrastructure is important for post-industrial city, especially in an era of climate change.

  • This study was intended to investigate the characteristics of muffins prepared with allulose which is low-calorie and physiologically functional rare sugar. Volume and specific volume of muffins increased significantly with allulose addition, but not with its contents. Muffin heights also increased as allulose was added more. Baking loss rate and moisture contents were not significantly different among samples. Allulose seemed to have nearly same water holding capacity with sucrose. Lightness of muffin crust and crumb both decreased, but redness and yellowness increased according to allulose, the reducing sugar addition by Maillard reaction. In the texture profile analysis, Hardness of AL100 was higher significantly (p<0.05) and springiness, cohesiveness and fracturability increased according to the allulose contents. In the sensory evaluation, AL0 was the sweetest and AL0 and AL25 got higher overall acceptance score. Physical characteristics were not different (p<0.05) among AL0, Al25 and AL50. As a result, 25% sucrose substitution with allulose can provide low-calorie, anti-hyperglycemic and tasty muffin.

  • Reducing the fat content of processed meat products can be performed by (1) using leaner raw meat materials (2) inducing non-meat ingredients that serve to replace a portion or all of the fat, and (3) applying new ingredient combinations, technologies or processing procedures that decrease the fat and cholesterol content of meat products. Low-fat meat products were manufactured with Int replacers which were food ingredients that had the functional and sensory properties of fat without contributing fat calories, resulting in lower fat(<3%) content. Added water, non-meat proteins, carbohydrates, such as starch and hydrocolloids(gums) and vegetable oils have been used as typical fat replacers to be used in meat products. In addition, fat substitutes included structural lipids, sucrose polyester and ingredient combinations. Formulations for the manufacture of low-fat meat products in combined with new technologies have focused on the use of fat replacer combinations that contributes a minimum of calories and not detrimental to flavor, juiciness, mouthfeel or textural traits expected more traditional products. In conclusion, some combinations of fat replacements that mimics the flavor, mouthfeel and textural characteristics of fat offer potential for further development of low-fat meat products to have similar characteristics of regular-fat counterparts.
