This study analyzed the nutritional composition (proximate composition, total dietary fiber, calories, minerals, fatty acids, and amino acids) of 10 noodle products (tteok ramyun, jjamppong ramyun, kimchi ramyun, instant udon, cup ramyun, jajangmyun, bibimmyun, cream spaghetti, ssalguksu, and milmyun), which account for 85% of the cumulative intake of one or more key nutrients, using data from the 7^th Korea National Health and Nutrition Examination Survey. The moisture contents of bibimmyun, jajangmyun, and cream spaghetti were lower than those of the other noodle products, whereas the crude fat, crude protein, carbohydrate, and calorie contents were the highest. Cream spaghetti had the highest mineral, fatty acid, and amino acid contents, followed by bibimmyun and jajangmyun. Ssalguksu had the lowest contents of most nutrients. These data could be used to populate a food composition database, which can provide consumers with the nutritional information about frequently consumed noodle products.

In this study, we aimed to investigate the effect of Chinese gooseberry (kiwi)-based products on the improvement of intestinal function and constipation. In this study, 21 participants with no underlying disease and complaining of subjective constipation symptoms were selected. Through a pre-experimental design, the main effects, including the colon stagnation score and colon transit time, were assessed after the consumption of Chinese gooseberry (kiwi)-based products. To evaluate the side effects of this product, a subjective constipation assessment test was performed to analyze the degree of constipation improvement at an individual level. The results for the main effects revealed that the number of constipation groups was statistically significantly decreased, and the colon stagnation score and colon transit time were also reduced. Additionally, the participants' subjective constipation assessment test revealed a significant improvement in both intestinal function and bowel activity before and after the consumption of Chinese gooseberry (kiwi)-based products. Similar to the previously known kelp-, lactobacillus-, and fiber-based products, we showed that Chinese gooseberry (kiwi)-based products exert a significant effect on the improvement of the intestinal function and constipation. Furthermore, the results of this study provide valuable information for the development of healthy food products in the future that can help improve bowel movement. Moreover, Chinese gooseberry (kiwi) used in this study is not a functional food and is easily accessible. However, this study has several limitations as it is based on a pre-experimental design. Therefore, studies on randomized experimental and control groups are needed in the future.

A Korean traditional food, sulgidduk, was prepared with the supplementation of whole wheat flour (WWF) high in dietary fiber, and its quality characteristics were investigated depending on the WWF content (3, 5, and 7%). There was no significant difference found in moisture content of final products. Colorimetric analysis revealed that L-value representing brightness decreased with increasing WWF content. In texture profile analysis, freshly-made samples did not show measurable difference in hardness depending on WWF content. However, stored samples at 25$^{\circ}C$ for up to 3 days exhibited a decrease in hardness with increasing WWF content, indicating retardation of retrogradation related to WWF addition. Springiness and chewiness values showed decreasing trend with WWF content especially for stored samples. Retardation of retrogradation with WWF addition was also evidenced by observing the increment of time constant calculated from Avrami equation. Analysis of sensory evaluation demonstrated that considering flavor, taste, texture, and overall acceptability, 5% substitution of rice flour with WWF could be a promising formulation for quality product with high nutritional value.

Mulberry is a hardy, perennial, deep-rooted plant capable of thriving under diverse agroclimatic conditions. The selection of suitable land and appropriate variety can help the sustainable mulberry field. However, no conclusive and comprehensive investigation has been conducted on the mulberry soil properties and nutritional composition of mulberry cultivars from Korea local areas in previous studies. In our study, soil properties and mulberry leaf components of Korea local mulberry farms were briefly investigated. In result, the soil organic matter (OM) content was significantly high in Buan (6.81%) and Jangseong (6.14%). In contrast, available phosphate (P₂O₅) was different in each local area. To investigate relationship between soil property and nutritive component of mulberry leaf, Cheongil leaf samples from 8 local areas were analyzed. Among the macrominerals (K⁺, Ca²⁺, Na⁺, and Mg²⁺), the concentration of K varied from (1884±9.36) mg/100 g to (2685±11.5) mg/100 g. The potassium (K⁺) of Cheongil leaf in Sangju was the highest at 2685 mg/100 g. Besides macrominerals, flavonoids, total dietary fiber contents and moisture of Cheongil leaf samples were studied in the 8 local areas. In terms of these contents, the variation was largely depending on the local areas. This study provides a possible industrial use of mulberry, and holds promise to enhance the overall profitability of sericulture.

Two experiments were undertaken to study the growth promoting effect of Spiramycin and Virginiamycin at the level of 5ppm each. In the first experiment, 180 day - old male broiler chickens (Maniker parent stock) were divided into 18 groups of 10 birds each. Six groups were placed on one of the three experimental diets (Nonmedicated control, Spiramycin supplemented diet and Virginiamycin supplemented diet). Basal diet of Experiment 1 contained 21.9% crude protein and 3159kcal /kg diet. Second experiment employed same treatments as were used in the Experiment 1. Ninety male and 90 female day-old broiler chickens(Maniker commercial) were grouped by 10 birds of sane sex in each and assigned to 3${\times}$2 factorial design. Basal diet of Experiment 2 contained 19.95% crude protein and 2931kcal/kg diet. Chicks were fed for six weeks in battery with raised floor and kept further for metabolic trials. The results of feeding trials showed that there were no statistically significant differences between treatments in weight gain, feed intake, feed efficiency and mortality. However, birds fed Antibiotic B supplemented diet grew approximately 3% more than the control in Experiment 1 and than those fed Antibiotic A supplemented diet in Experiment 2. Feed efficiency was also improved by supplementing Antibiotic B in both experiments. There were significant(P〈0.01) differences between sexes in growth rate, feed intake and feed efficiency. Birds fed Antibiotic B supplemented diet of Experiment 1 showed significantly (P〈0.01) greater availability for crude fat than those fed other diets. Birds fed Antiobiotic A supplemented diet in Experiment 1 showed significantly (P〈0.05) lower availability of crude fiber than those of other treatments. Weight of small intestine of birds fed Antibiotic B tended to be heavier than those fed other diets.

Medical foods are enteral nutrition for patients, but they cause maladaptation symptoms like diarrhea. Although the cause of diarrhea remains unknown, some studies have indicated that the cause of diarrhea is fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP). This is a consideration for medical foods since they are easily fermented by intestinal bacterial. In this study, we estimated the FODMAP contents of commercial medical foods and carbohydrate ingredients. We measured the concentrations of FODMAP in 13 types of different medical foods and five types of carbohydrate ingredients by using high performance liquid chromatography with an evaporative light scattering detector (HPLC-ELSD). The limits of detection of FODMAP were fructose, 0.002; lactose, 0.010; raffinose, 0.003; stachyose, 0.032; 1-kestose, 0.005; nystose, 0.012; and 1-fructofuranosylnystose, 0.003 mg/kg. Limits of quantitation of FODMAP were fructose, 0.008; lactose, 0.033; raffinose, 0.009; stachyose, 0.107; 1-kestose, 0.015; nystose, 0.042; and 1-fructofuranosylnystose, 0.011 mg/kg, respectively. Concentration of FODMAP ranged from 0.428~2.968 g/200 mL. Concentrations of carbohydrate ingredients in FODMAP were chicory fiber, 278.423; soy fiber, 27.467; indigestible maltodextrin, 52.384; maltodextrin (DE10~15), 32.973; and maltodextrin (DE15~20), 50.043 g/kg. Contents of carbohydrates were 19.0~41.0 g/200 mL in commercial medical foods. We expected a correlation between contents of carbohydrates and FODMAP, as carbohydrates included FODMAP. However, we detected a low correlation (r=0.55). Since most commercial medical foods have a similar carbohydrate ingredients and nutritional values, the difference between products was determined by FODMAP contents of carbohydrate ingredients. In this study, we analyzed FODMAP contents of commercial medical foods and carbohydrate ingredients. These results are expected to be utilized as basic data for product development and minimizing maladaptation of medical foods.

This study was to assess the effect of sowing mixed legume forage and applying cattle manure on the productivity and feed value of whole-crop barley (WCB) as a representative of winter crops and to estimate feeding capacity of Korean native cattle (Hanwoo) per unit area by defining optimal application level of cattle manure for more fertile soil and manure recycling for the purpose of reduced environmental pollution and efficient production of organic forage contributable to production of organic animal products. Sowing mixed legume forage significantly (p<0.05) increased yields of dry matter (DM), crude protein (CP) and total digestible nutrients (TDN) for WCB compared to WCB alone sowing, but there was no difference between mixed sowing treatments. The yields of DM, CP and TDN were significantly (p<0.05) highest in 100~150 kg N/hg. The CP and acid detergent fiber (ADF) contents were highest in mixed sowing with hairy vetch, followed by sowing mixed forage pea and WCB alone (p<0.05). There were no differences in CP and neutral detergent fiber (NDF) contents among cattle manure application levels. As nitrogen application level increased, ADF content increased (p<0.05), but TDN content decreased (p<0.05). Feeding capacity of organic Hanwoo (head/ha) weighing 450 kg of body weight with 400 g of daily gain significantly (p<0.05) increased due to mixed sowing with legume forage, and with increasing application levels of fermented cattle manure, feeding capacity significantly (p<0.05) increased. The results indicate that mixed-sowing of WCB and legume forage not only cut nitrogen application level of fermented cattle manure by over 50 kg per ha but also increased their feed value and productivity, and feeding capacity. This would be contributable to diversity of forage resources as well as production of organic animal product by creating low cost and high quality of forage.

This study was aimed to grow organic forage as a prime requirement for organic Hanwoo cattle production over a period of 3 years (2012~2015) in Gyeongbuk region, Korea through mixed cropping of winter fodder barley with legume and application of fermented cattle manure. The effect of barley-legume mixed cropping and application of different levels of fermented cattle manure was studied on forage productivity of whole-crop barley (WCB) and evaluation of feeding capacity of Korean native cattle (Hanwoo) per unit area. The collected data was analyzed using SAS 9.3 software. Barley-legume mixed cropping increased (P<0.05) yields of dry matter (DM), crude protein (CP) and total digestible nutrients (TDN) as compared to those of sole WCB as monoculture. Similarly, acid detergent fiber (ADF) contents and relative feed value (RFV) were also higher (P<0.05) in barley-legume mixed sowing forage compared with those of sole WCB as monoculture. In case of manure application, yields of DM, CP and TDN were also found (P<0.05) highest in 100~150 kg N/ha. However, varying cattle manure levels did not influence (P>0.05) CP and neutral detergent fiber (NDF) contents. In response to increasing nitrogen application level, ADF content increased (P<0.05) but TDN content and RFV decreased (P<0.05). The Barley-legume mixed sowing and increasing application levels of fermented cattle manure also significantly enhanced (P<0.05) feeding capacity of organic Hanwoo (head/ha) having 450 kg body weight with 400 g of daily gain. Findings of present study indicated that barley-legume biculture not only cut nitrogen application level of fermented cattle manure by over 50 kg per ha but also increased their feed value and productivity of forage as compared to WCB monoculture. This would be contribution to the diversity of forage resources as well as production of organic animal product by creating low cost and high quality organic forage.

To enhance the applications of apple pomace, which is a by-product of apple, this study analyzed the nutritional components, ursolic acid content, and antioxidant activity of different solvent (distilled water, fermented alcohol, and methanol) extracts. The samples included hot air-dried and freeze-dried apple pomace. The moisture, protein, fat, ash, and total dietary fiber contents of hot air-dried apple pomace were 3.2%, 3.9%, 2.4%, 2.0%, and 28.5%, respectively, and those of freeze-dried apple pomace were 8.2%, 3.4%, 2.4%, 1.8%, and 33.0%, respectively. Ursolic acid was not detected in the distilled water extract of either sample. However, in hot air-dried apple pomace, the methanol extract was 1,753.32 ㎍/ml, and the fermented alcohol extract was 1,532.94 ㎍/ml. In freeze-dried apple pomace, the methanol extract was 1,407.04 ㎍/ml, and the fermented alcohol extract was 1,221.81 ㎍/ml. The total polyphenol and flavonoid contents were 306.7 ㎍/ml and 950.1 ㎍/ml, respectively in methanol extracts of hot air-dried apple pomace and 277.6 ㎍/ml and 925.0 ㎍/ml, respectively in methanol extracts of freeze-dried apple pomace. 2, 2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities of hot air-dried apple pomace were 73.3% in methanol extract and 59.4% in fermented alcohol extract, and those of freeze-dried apple pomace were 76.1% in methanol extract and 66.0% in fermented alcohol extract. Both samples had the lowest antioxidant activity in distilled water extracts. Similar to DPPH radical scavenging activity, both samples showed increasing 2,2'-azino-bis(3-ethylbenzothiazoline-6- sulfonic acid) (ABTS) radical scavenging activity in the order of methanol, fermented alcohol, and distilled water. All samples had stronger reducing power than ascorbic acid (311.5 ㎍/ ml) as a positive control.
