In this study, we attempted to find alternative materials to replace Cotten seed meal(CM) using the wastes of bean sprouts by-product in bottle cultivation of Pleurotus ostreatus. In Proximate analysis, the protein content of BW was slightly lower than that of CM, but the growth characteristics of mushrooms were similar to those of control when byproduct of bean sprouts was used. In addition, the amino acid composition of fruit body did not show a significant difference in the treatment section. Therefore, it is judged that BW could be a suitable substitute for CM in the cultivation of Pleurotus ostreatus.

Arctium minus (AM), commonly known as lesser burdock, is a dried fruit (seed) of Aructium lappa L. that belong to Asteraceae. It has been used traditionally as herbal medicine because of its anti-inflammatory effects, and it has been applied to treat various diseases like allergies, skin aging, hyperlipidemia and urinary stone. In this study, we investigated the inhibitory effects of AM on the production of pro-inflammatory cytokines in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Pre-treatment of the RAW 264.7 cells with AM considerably inhibited and reduced production of Nitric Oxide (NO) and pro-inflammatory cytokines, such as interleukin (IL)-6 and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and also shows suppression of nuclear factor-kappa B (NF-${\kappa}B$) translocation. In addition, AM treatment considerably reduced phosphorylation of mitogen-activated protein kinase (MAPK) in LPS-stimulated RAW 264.7 cells. Our results indicate that the AM has potential to inhibit inflammation through suppressing production of inflammatory mediators via both the NF-${\kappa}B$ and MAPK signaling pathway. We therefore suggest that AM might be effective therapeutics for the treatment of various inflammatory diseases.

Sparassis (S.) crispa is an edible mushroom abundant in dietary fiber and ${\beta}$-glucan. The aim of this study was to prepare extracts and residues of the fruit bodies of S. crispa fermented with Lactobacillus (L.) brevis and Monascus (M.) pilosus and to measure the remaining dietary fiber and ${\beta}$-glucan. Dried powder of S. crispa containing 64.4 g/100 g total dietary fiber (2.6 g/100 g soluble and 61.8 g/100 g insoluble dietary fibers) and 24.0 g/100 g ${\beta}$-glucan was used as the starting material for the extraction. Raw and fermented S. crispa were extracted with hot water and three kinds of aqueous ethanol (50, 70, and 90%, v/v), respectively. A hot water extract from S. crispa fermented with M. pilosus had greater soluble dietary fiber content (19.3 g/100 g) than that from raw S. crispa with 14.6 g/100 g soluble dietary fiber or that from L. brevis-fermented S. crispa with 8.2 g/100 g soluble dietary fiber. The yield of the extract was 16.6% of intial weight of dried S. crispa. After hot water extraction of S. crispa fermented with M. pilosus, residues containing 90.5 g/100 g total dietary fiber (1.3 g/100 g soluble and 89.2 g/100 g insoluble dietary fibers) were obtained, and the yield was 69.6% of intial weight of dried S. crispa. The residue (31.0 g/100 g) contained more ${\beta}$-glucan than raw S. crispa or M. pilosus-fermented S. crispa (24.4 g/100 g). The resulting hot water extract and residue from S. crispa fermented with M. pilosus would be suitable for use in preparing liquid and powdered health functional foods, respectively.

The present study seeks to find the effect of oral health status that parents recognized, oral health habit and food intake on existence of decalcified teeth and decayed teeth. Participants were 293 infants aged 18-24 months who visited C dental clinic in Kyungki province between January and December 2010. Questionnaires and oral exam results were used and statistically analyzed by the SPSS program. Fisher's Exact and chi-square test were used to analyze the data. The 18-20 month-old age group had the highest rate of decalcified teeth with 36.4% while the 23-24 month-old age group had the highest rate of decayed teeth with 37.0%. Bottle feeding showed correlation with decalcified teeth, and decayed teeth. Parents were able to recognize decayed teeth and decalcified teeth. Group 2 food(soda/soft drinks/sugared fruit juice) was related to decalcified teeth and decayed teeth(p<.001). Group 4 food (cake/cookies/doughnut/dried fruit/banana) and group 5food(caramel/candy/chocolate bar) were both related to decalcified teeth(p<.001). As the result of dental examination, dental treatment was highly needed for the 21-22 month-old age group(89.3%), and preventive treatment and plaque control were highly needed for the 18-20 month-old age group(94.5%). The results concluded that 18-24 months was the critical period for children's oral health, therefore organized oral health education for parents is necessary.

Corni fructus is often distributed or processed in the form of dried fruit. However, Corni fructus is hard to develop due to its distinctive sour, bitter, and astringent taste. The aim of this study was to develop a puree to broaden the utilization of fresh Corni fructus. Manufacturing and quality characteristics of Sansuyu jam made from puree were investigated. Seeded Corni fructus pulp consisted of 20 to 26% whole fruit. The moisture and sugar contents of pulp were 52~63% and $15{\sim}31^{\circ}Brix$, respectively. Sterilized distilled water was added to seeded pulp to achieve a constant solids content in the puree. As the pectin content was low as $0.14{\pm}0.01%$, gelling agent was added to produce jam. The moisture content of the puree increased to 83~88%. The sugar content was reduced to $10^{\circ}Brix$. There was no significant difference in pH. DPPH radical scavenging activities of the puree according to ripening rate at a concentration of 100 ppm were 47.92% and 50.96%, respectively. The preference degree was $5.03{\pm}0.97$ at a ripening ratio of 50:50, 2% pectin, and 0.2% carrageenan. These results imply that Corni fructus pulp puree may be appropriate for development as a natural food product.

$Prunus$ $mume$ was steamed for easier removal of the pulp. The steamed fruit pulp was vacuum dried and powdered. The steamed $Prunus$ $mume$ powder (SPP) was passed through a 250 ${\mu}m$ sieve, fluidized in a fluid-bed granulator, and then granulated by top-spraying with water (SPPGW) or the extract obtained from steam (SPPGE). Then the physicochemical and sensory properties of SPP, SPPGW, and SPPGE were evaluated. The flowability of powder (angle of repose $^{\circ}$) of SPP, SPPGW and SPPGE was $23.59^{\circ}$, $11.07^{\circ}$, and $13.94^{\circ}$, respectively. The water dispersibility of SPP, SPPGW, and SPPGE was 18.69, 10.04 and 6.00 sec, respectively. Also, the overall acceptance of SPP, SPPGW and SPPGE was 3.00, 3.44 and 6.56, respectively. In conclusion, SPPGE can be used as granular steamed whole fruit pulp with good powder flowability and dispersibility, and therefore consumer acceptance.

We conducted this study to investigate the morphological characteristics and physiological effects of mulberry leaves and fruits with wild varieties. Morphologically sampling materials were showed Morus bombycis type and Morus alba type characteristics. Water contents of mulberry fruits were higher than that of mulberry leaves. Sugar degree of sampling materials was 5.1∼22.7 Brix %. The yield of 85% MeOH extract from freezing dried Mulberry Fruits was 60.2% and Hexane, BuOH and H$_2$O fraction from MeOH extract were 2.8%, 4.6%, 92.3% respectively. In the cholesterol-induced hyperlipidemia rats administered with subfraction of mulberry fruit extract, total cholesterol and serum triglyceride were decreased in the MeOH extract group and H$_2$O soluble fraction group. Also H$_2$O soluble fraction group decreased GPT, GOT and LDH level. Therefore, the above results suggested that mulberry fruit with wild varieties can help to maintain normal liver functions and to protect hyperlipidemia.

We investigated the effects of manufacturing method on the quality of beef jerky using electron micrography. Six types of beef jerky were prepared by the addition of sugar (A), licorice (B), one of three kinds of spice extract (clove: C, fennel fruit: D, and Chungyang green pepper extract: E), or a mixture of all spice extracts (F). Microstructural changes in beef jerky during preparation by drying, with respect to drying method and the nature of the added spice extract, were observed by scanning electron micrography (SEM) and transmission electron micrography (TEM). The latter technique showed that the microstructure of fresh meat showed actin and myosin in myofibril lines, and also mitochondria and inner membranes. Beef muscle structure was broken at many myofibril lines and decomposition of inner membrane material was evident after seasoning. SEM of air-blast dried beef jerky with added medicinal herb extracts showed both large spaces and regular myofibrils, whereas hot air-dried beef jerky had no spaces and the muscle myofibrils were still evident. After review of all available micrographs from SEM and TEM, we concluded that use of medicinal herb extracts could be helpful in preserving the muscle myofibril structure during drying, and the air-blast drying method is recommended to optimize the textural quality characteristics of beef jerky.

Goji berry (Lycium chinense Mill.) is one of medicinal plants. Its leaves has been used to manufacture the functional foods by replacing the dried-fruit because of low production costs. In order to produce the leaves of uniform quality, continuous selection and the establishment of cultivation techniques were required. Among the eleven recommended cultivars, 'Myeongan' showed high yielding and rapid regeneration after cutting. The dried-leaf yield was linearly increased from 106 kg/10a on May 16 to 287 kg/10a on June 20. An appropriate cutting date and cutting length (about 60-70 cm) was important factors for its efficient regeneration. The late cutting times were not suitable due to difficulties during plant harvesting because of stem rigidity and thorn generation. The betaine content of leaves ranged from 1.43 ~ 2.63% and significantly affected by the varieties and the cutting dates. The main physiological functionality of leaf was Angiotesin-1-converting enzyme (ACE) inhibitory activity, representing the anti-hypertensive. The other physiological functionalities, XOD inhibitory activity, antioxidant activity, tyrosinase inhibitory activity, SOD-like activity, α-glucosidase inhibitory activity and fibrinolytic activity, were not detected or less than 20%.
