  • This review was conducted to evaluate the 'Korean Food Composition Table' and establish it as an internationally accepted database by examining its contents and evolution over time. The food composition table has been published by National Rural Living Science Institute, every 5 years, listing the nutrient content for each food, as both the raw agricultural product and processed foods, since the 1$^{st}$ edition in 1979 by RDA (Rural Development Administration). This is the basic data applied to the evaluation of the nutritional value of foods in Korea. The data is used as a useful tool in many fields, not only for the establishment of the National Food Supply Plan but also for nutritional research, the draft of National Food Policy, and in clinical and epidemiological research. The database is also utilized by food service providers and food processors, etc. Consumers and the international society have been interested in the quality and safety of foods and raw agricultural products. As these data expand in volume, the type of foods included in the composition table is expanded to cover new additions for the convenience of users of the 'Nutrient Data Base' as judged by the publishers. The form of these reports varies, according to the current information, from a simple booklet to CD-ROM and to the Web service. We expect to continue to make improvements in the National Standard Table for food composition through expanding both the quantity and quality of data in an orderly manner. This effort can help food composition data to be comprehensively developed systematically and gradually at the national level.l.

  • This experiment was carried out to compare with the physico-chemical properties of granular fused magnesium phosphates which were two domestic products(Pungnong Biryo Industrial Co., LTD and Kyunggi Chemical Industrial Co., LTD) and a imported Chinese product. The changes of pH, distribution of particle size, disintegration in water and in soil, hardness in soil, chemical composition, and dissolution rates in water, in soil and in 2% citric acid solution were investigated. The changes in pH were bigger in Jungmun series(black volcanic soil), in the imported chinese product, and in Jungmun series with the larger quantities applied. The domestic products were lower in pH, calcium, alkalinity and 1/2N-HCl soluble silicate than the Chinese product but total(Aqua regia) soluble phosphate, 2% citric acid soluble phosphate, 1/2N-HCl soluble and 2% citric acid soluble magnesium, and 2% citric acid soluble manganese concentration were similar among the domestic products and the imported product. In particle sizes, Chinese product was the biggest, Kyunggi product was the next, and Pungnong product was the smallest. The changes of disintegration rate in water and in soil were smaller in Pungnong and Kyunggi products at the early days of dissolution, and there were decreased with the order of Kyunggi product> Chinese product> Pungnong product at the latter days. The hardness of the products in soil was the strongest in Kyunggi product, the next was Pungnong product and Chinese product was the weakest so as to hardly measurable. The changing dissolution rates of 2% citric acid soluble phosphate concentration of granular fused magnesium phosphate products were the highest in Kyunggi product and the lowest in Pungnong product at the early days, the three products were dissolved over 90% within 50 days, and there were no clear difference among the products after 70 days of dissolution. The dissolution rates of 2% citric acid soluble phosphate concentration of granular fused magnesium phosphate products in soil were the highest in Pungnong product and Chinese product was the lowest, but they were less than 60% in 100 days of dissolution.

  • This experiment was conducted to determine the optimum level of green tea by-product (GTB) in diets without antibiotics and to evaluate its effect on broiler performances. A total of 140 Ross broilers were kept in battery cages for a period of 6 weeks. Dietary treatments used in this experiment were antibiotic free group (basal diet as a control), antibiotic added group (basal+0.05% chlortetracycline), GTB 0.5% (basal+GTB 0.5%), GTB 1% (basal+GTB 1%) and GTB 2% (basal+GTB 2%). Antibiotic added group showed significantly higher body weight gain than other treatments (p<0.05). However, no significant differences were observed in feed intake and feed efficiency among treatments (p>0.05). The addition of green tea by-product to diets tended to decrease blood LDL cholesterol content compared to control group although there were no significant differences among treatments (p>0.05). Addition of green tea by-product increased docosahexaenoic acid (DHA) in blood plasma and tended to decrease cholesterol content in chicken meat, but a significant difference was not observed (p>0.05). The values of TBA in chicken meat decreased in groups fed diets with green tea-by product and antibiotics compared to control group (p<0.05). The crude protein content in chicken meat was decreased slightly in treatments with green tea by-product and antibiotics supplementation. The abdominal fat was increased in chickens fed with diets with green tea by-product compared to the control (p<0.05).

  • In this study, degradation of carbohydrates and composition of fermentative products were investigated in semi-continuous acid fermenter varying hydraulic retention time (HRT). Rice soup was used as a sole substrate for the acid fermentation. Solubilization efficiency of the substrate was higher than 70% for all HRT, however the gas conversion was ignorable implying that most of organic contents in the influent remained in the form of volatile fatty acids (VFAs) and ethanol after acid fermentation. The VFAs were the predominant product and the VFAs conversion increased as the HRT decreased. The VFAs conversion reached the maximum value at 12 hr HRT accounting for 70% of the influent COD. Similar to VFAs, ethanol conversion was increased with the decrease of HRT and the maximum ethanol conversion efficiency was 8% at the HRT of 12 hr. Composition of VFAs was markedly dependent on HRT. As HRT increased, the composition of acetic acid was increased as a product of acetogenesis from butyrate, valerate and ethanol. This study demonstrated that HRT affected acid fermentation of a carbohydrate containing organic wastes producing VFAs and ethanol which could be effectively used to compensate the lack of carbon in wastewater for biological nutrient removal.

  • Pastirma is a dry-cured meat product, produced from whole beef or water buffalo muscles. This study was carried out to investigate the effect of production stages (raw meat, after curing, after $2^{nd}$ drying and pastirma) on the total lipid, neutral lipid, phospholipid and fatty acid composition of phospholipid fraction of pastirma produced from beef M. Longissimus dorsi muscles. The pH and colour ($L^*$, $a^*$ and $b^*$) analyses were also performed in raw meat and pastirma. It was found that pastirma production stages had significant effects (p<0.01) on the total amounts of lipid, neutral lipid and phospholipid, and the highest amounts of lipid, neutral lipid and phospholipid were detected in pastirma. In pastirma, neutral lipid ratio was determined as $79.33{\pm}2.06%$ and phospholipid ratio as $20.67{\pm}2.06%$. Phospholipids was proportionately lower in pastirma than raw meat. Pastirma production stages affected pentadecanoic acid (15:1) (p<0.01), linoleic acid (18:2n-6) (p<0.05), ${\gamma}-linoleic$ acid (18:3n-6) (p<0.05), erucic acid (22:1n-9) (p<0.05), docosapentaenoic acid (22:5n-6) (p<0.05), total unsaturated fatty acid (${\Sigma}USFA$) (p<0.05) and total saturated fatty acid (${\Sigma}SFA$) (p<0.05) ratios of phospholipid fraction and also the moisture content (p<0.01). Pastirma process also affected pH and colour ($L^*$, $a^*$ and $b^*$) values (p<0.01), and these values were higher in pastirma than raw meat.

  • Isothermal pyrolysis of high density polyethylene(HDPE), polypropylene(PP) and polystyrene(PS) was performed at $450^{\circ}C$, respectively. The effect of pyrolysis time on yield and product composition was investigated. Conversion and liquid yield obtained during HDPE pyrolysis continuously increased with time up to 80minutes, but those of PP and PS did not largely change after 35minutes. Each liquid product formed during the pyrolysis was classified into gasoline, kerosene, light oil and wax according to the distillation temperature based on the petroleum product quality standard of Korea Petroleum Quality Inspection Institute. The major liquid product of HDPE pyrolysis was light oiH34 wt.% based on the amount of HDPE treated) and the amounts of the other liquid ingredients(gasoline, kerosene and wax) were almost the same. On the other hand, the pyrolysis of PP produced 27 wt.% gasoline, 22 wt.% kerosene, 24 wt.% light oil and 13wt.% wax, and the pyrolysis of PS produced 56 wt.% gasoline, 12 wt.% kerosene, 9 wt.% light oil and 13 wt.% wax.

  • Purpose - With the recent spread of COVID-19, U.S. consumers' consumption pattern is changing towards purchasing large-capacity products, as they stay at home longer. Thus, the current research investigates the effects of box shape and component diversity for large-sized products on product evaluation in logistic business. Moreover, this research examines that information-processing fluency mediates the moderating effects of box shape and product components on target evaluations to confirm psychological mechanism for generating this effect. Design/methodology - In order to examine the hypotheses, the current research conducts two online experiments. The 184 participants (Study 1), and 205 participants (Study 2) of U.S. nationality were recruited through Amazon Mechanical Turk. This research analyzes the data by using SPSS 25 and PROCESS macro 4.0. Findings - Study 1 demonstrates that when the height of a box is greater than its width, products with single components promote positive target evaluations, while when the width of box is greater than its height, products with a variety of components lead to positive target evaluations. Study 2 shows that the same results are replicated in other product categories and with different box shape ratios. Moreover, Study 2 also finds that the ease of information processing mediates the interaction effects of box shape and component diversity on U.S. consumers' target evaluations. Originality/value - The current research has originality in that it investigates the effect of box shape and product composition diversity on U.S. consumer product evaluation from the perspective of information-processing theory Moreover, this research has practical implications for global traders who prepare for entering the U.S. market.
