  • An experiment was conducted to increase the quality of rice bran by fermentation using Bacillus amyloliquefaciens and humic substances and its utilization as a feed ingredient for broiler chickens. The experiment was carried out in two steps. First, the fermentation process was done using a completely randomized design in factorial with 16 treatments: i) Dosage of B.amyloliquefaciens ($2.10^8cfu/g$), 10 and 20 g/kg; ii) Graded levels of humic substances, 0, 100, 200, and 400 ppm; iii) Length of fermentation, three and five days. The results showed that the fermentation significantly (p<0.05) reduced crude fiber content. The recommended conditions for fermentation of rice bran: 20 g/kg dosage of inoculums B. amyloliquefaciens, 100 ppm level of humic substances and three days fermentation period. The second step was a feeding trial to evaluate the fermented rice bran (FRB) as a feed ingredient for broiler chickens. Three hundred and seventy-five one-day-old broiler chicks were randomly assigned into five treatment diets. Arrangement of the diets as follows: 0%, 5%, 10%, 15%, and 20% level of FRB and the diets formulation based on equal amounts of energy and protein. The results showed that 15% inclusion of FRB in the diet provided the best bodyweight gain and feed conversion ratio (FCR) values. In conclusion, the nutrient content of rice bran improved after fermentation and the utilization of FRB as a feed ingredient for broiler chickens could be included up to 15% of the broiler diet.

  • Background: The Korean government launched a project in 2008, where the amount of rice used as raw ingredient in rice-based foods in 2012 was planned to increase up to 10% (470,000 ton) of the total rice production through developing various new rice-based processed foods and their commercial manufacturing technology. Among the four major rice-based processed foods, rice cakes and noodles need rice flour as their main raw ingredient. Technology in rice flour utilization and manufacturing is far behind than the technology pertinent to wheat flour in many subject areas. Purpose: This review aims to provide information on rice flour utilization and manufacturing with some fundamental subjects in the area of size reduction. Results: A variety of food items including bread, noodle, cake, cookie, muffin, pre-mix, beverage, vinegar, surimi, and artificial meat have found rice flour as their raw ingredient. Rice bread made out of 100% rice flour has been developed and is now sold in retail stores. Various noodle products made from rice flour are also on the market. Issues on product definition and labeling regulation about rice flour content of the products were explored. Generalized grinding equations available in the literature were seldom used in practice; instead, it has been a general practice to develop empirical equations from test milling data. Introductory remarks on three popular particle size measurement methods (sieving, Coulter counter, light diffraction) were explained. Mathematical expressions frequently used to describe particle size distribution and to correlate cumulative quantity of particles with particle size were represented. Milling methods used in producing rice flour were described along with their advantages and disadvantages. Because of their profound effect on functional properties of the rice flour, four rice flour milling equipments used at both laboratory experiments and commercial manufacturing plants were discussed.

  • This paper is a review of some experiments using black soldier fly (BSF) and its by-product to explore their nutritional value, production potential in Indonesia and its application in the ration of ruminants. Evaluation on the effect of milk replacer, creep feed containing BSF, BSF frass and the possibility to use lactic acid bacteria from BSF as probiotics are presented. Utilization of BSF larvae in milk replacer as skim and cream milk substitute showed that there were similarity on physiological, hematological status and performance of goat kids compared to those offered goat milk or commercial milk replacer. In addition, BSF larvae can be used to substitute soybean meal in the creep feed for post weaning goat kids without any differences in weight gain and blood profiles. However, utilization of BSF frass in the fattening goat ration resulted lower digestibility of dry matter and organic matter due to the chitin content in the frass. Black soldier fly larvae grown on chicken manure harbour lactic acid bacteria (LAB) which have potential as probiotics for ruminants. In general, BSF larvae has potential as ingredient for milk replacer, creep feed, fattening ration, and source of LAB for probiotics.

  • In an effort to protect consumers' rights to information and to promote their freedom of choice, the South Korean government has been enforcing a policy called the cosmetics full ingredients list system since 2008, which requires cosmetics manufacturers to list all of the ingredients used in their products. This policy aims to assist consumers in identifying the causes of possible side effects of cosmetic products. This study uses consumers' demographic information addition to their cosmetics purchase and usage characteristics to learn about consumers' attitudes and utilization intentions and the influence of information from the cosmetics full ingredients list. This study was conducted through a questionnaire based survey administered to women above the age of 20 years across South Korea who use cosmetic products. The questionnaire was distributed to 300 members on the panel of M Brain, an online research institute. The findings of this study are as follows: (1) The level of knowledge on cosmetics' ingredients positively affected the consumers' attitude and utilization intention of information on the cosmetics full ingredients list. (2) The higher the utilization intention for information, the more often consumers checked the packaging of goods. This implies that habitual behavior, such as checking information, leads to increasing intention to utilize of new information. (3) The brand, as a decision-making factor, negatively affected consumers' attitudes regarding information.

  • Artemisinin, the effective ingredient of Chinese herb Artemisia annua L (Qinghao in Chinese), has been proved to be effective to antimalarial. Herein, a reliable, sensitive and convenient electrochemical method was developed for the determination of artemisinin utilizing the excellent properties of multi-wall carbon nanotube (MWNT). The electrochemical behavior of artemisinin was investigated. It is found that the reduction peak current of artemisinin remarkably increases and the peak potential shifts positively by 240 mV at the MWNT film-modified electrode. These phenomena indicate that the MWNT film exhibits efficient catalytic activity to the electrochemical reduction of artemisinin. The effects of pH value, amount of MWNT, scan rate and accumulation time were examined. The limit of detection (S/N = 3) is as low as 10 $\mu$ g $L^{-1}$. Finally, this newly developed method was used to determine the content of artemisinin in Artemisia annua L.

  • The cost of artificial diets for silkworm is very expensive, so that it is essential to lower it in order to extend the period of silkworm rearing on artificial diets. In the present paper, the utilization of several kinds of grass powders was tried to use as an ingredient of artificial diet to reduce its production cost. The value of grass powder as an ingredient of artificial diet was assessed on the base of ingestability and growth of silkworms. As a result it was found it was found that they varied with the kinds and harvesting season of grasses. But it is appeared to be possible to use a grass powder as an ingredient for silkworm diet, when it contains 10~20% of grasses. Moreover, to cut the cost of diet, it is recommanded that the diet containing grass powder could be a applied to the polyphagous silkworm variety.

  • This study was conducted to examine the effects of dietary cellulose levels on growth, nitrogen utilization, the retention time of diets in the digestive tract, and caecal microflora of 2-month-old Single Comb White Leghorn male chickens fed 3 purified diets that contained 0, 3.5% and 10% cellulose in equal amount of nutrients for 7 days. Body weight gain and nitrogen utilization were significantly higher (p<0.05), while total microflora counts in the caecal contents and retention time of the diet in the digestive tract were significantly lower (p<0.05) in the group fed 3.5% dietary cellulose compared with the group fed 10% dietary cellulose. Body weight gain, nitrogen utilization and retention time of the diet in the digestive tract decreased significantly while the total microflora count in the caecal contents increased significantly in the group fed 10% dietary cellulose compared to the group fed 0% dietary cellulose (p<0.05). Chickens fed 10% dietary cellulose had significantly increased counts of uric acid-degradative bacteria such as Peptococcaceae and Eubacterium, including Peptostreptococcus (p<0.05). The results suggest that cellulose in purified diets is an effective ingredient and the effects on growth, nitrogen utilization, caecal microflora counts and diet retention time in the digestive tract are dependent on the inclusion rate. Positive or negative effects of dietary cellulose are displayed by growth, nitrogen utilization, caecal microflora counts and retention time of the diet in the digestive tract. Positive effects were displayed when the inclusion rate is 3.5% and negative effects were displayed when that is greater than 3.5% of the diet, and the phenomenon is without reference to the age of the chickens.

  • This study was conducted to understand the perception and the usage pattern of egg dishes in university students. The questionnaires were collected from 200 university students residing in Seoul. The age group was 118 (59.0%) in 20s, 50 (25.0%) in 30s, and 32 (16.5%) in 40s and older. Also, 179 (89.5%) were undergraduate students and 21 (10.5%) were graduates. The result of food preferences in the overall survey was as follows: Meats and Poultry (4.46±1.03) > Seafoods (2.92±1.41) > Fruits (2.91±1.17) > Eggs (2.50±1.10) > Vegetables (2.21±1.17). The preference of foods using eggs as the main ingredient was as follows: Rolled egg (4.07±0.81) > Steamed egg (4.05±0.91) > Scrambled egg (3.83±1.03) > Rice omelet (3.77±1.03). The preference of foods using eggs as sub-ingredient was Egg in Ramyeon (4.11±1.08) > Fried egg over Bibimbob (3.87±0.91) > Sliced boiled egg in Naengmyeon (3.78±1.11). The preference of eggs as desserts was Egg tart (4.01±1.08) > Sponge cake (3.72±1.09) > Egg bread (3.63±1.13). The result of the frequency of eating eggs indicating that approximately two-thirds of university students consumed eggs more than 3 times a week. Although there was no significant difference, male students not only consumed eggs more frequently than female students, but also consumed a higher amount. In recent years, since one-person household in college students tends to increase, it is more important to save cooking time and food quality. Thus, the development and dissemination of various egg recipes should be prioritized for university students.

  • This study was to determine the inappropriate drug use in pediatric outpatients who received 2 or more prescriptions on the same day. Retrospective drug utilization reviews (DURs) were implemented to samples obtained from national health insurance claims data during December 2008 to February 2009, using 5 DUR criteria (duplication, drug-drug interaction, drug-disease interaction, drug-age contraindication, incorrect dosage) established in the Drug Information Framework (DIF)-$Korea^{TM}$, DUR program. Among 38,451 claims analyzed in the study, 74.7% had more than one conflicts in the 5 DUR modules. Among 16,472 patients analyzed, 49.6% had conflicts with duplication criteria composing of ingredient duplication (23.3%) and therapeutic class duplication (39.6%). Incorrect dosages were found in 73.6% of patients and under-dosage conflicts accounted for 59.9%, which was higher than over-dosage conflicts (38.3%). In this study, inappropriate drug prescriptions such as under-dose, pediatric contraindication and therapeutic duplication were prevalent in pediatric outpatient settings, suggesting much more awareness to the society, to prevent drug related problems in a vulnerable pediatric group.
