This study was designed to evaluate the improvement in exercise endurance by Hovenia dulcis fruit hot water extract (HDWE) for the potential application as a functional food material. The effect was based on the evaluation of the forced-swimming capacity and changes in biochemical parameters in mice. Six-week-old mice were classified into four groups based on a randomized block design: the negative control group, the HDWE 50 mg/kg body weight group, the HDWE 200 mg/kg body weight group, and the 1-octacosanol 50 mg/kg body weight group (n=8 mice per group). The swimming exercise time in the HDWE-50 group was increased at 545±43 sec compared to the control group at 263±28 sec. The HDWE-200 fatigue indicators, lactate acid and ammonia content, decreased to 4.99±0.33 mg/mL and 0.63±0.05 mg/mL, respectively. In addition, the content of glycogen in the liver and muscle tended to increase in the group administered HDWE but was not significant. Likewise, the LDH and glucose contents were increased compared to the control group. The muscle damage indicators ALT (52.7±2.6 U/L) and AST (42.5±5.2 U/L) tended to decrease compared to the control group (76.4±10.2 U/L).

The degree of milling is an important factor in terms of the nutritional value and the economic return of the milled rice. This study was to investigate the changes in compositions of the oils obtained from rice with different degree of milling. The content of total tocols in rice significantly (p＜0.05) decreased, as degree of milling increased. The relative ％ of -tocopherol in brown rice had lower than those in milled rices whereas the relative ％ of -tocotrienol, and -tocotrienol in brown rice higher than those in milled rices. -Oryzanol content significantly (P<0.05) decreased from 198.5 mg/kg rice for brown rice (0% milling) to 65.5 125.0 mg/kg rice for rice samples with 5.6, 8.0, and 9.6 ％ milling. -Sitosterol was most abundant sterol representing 50 ％ - 56% of the total sterol content in all analyzed samples. The content of total sterol as well as each sterol isomers in rice significantly (P<0.05) decreased, as degree of milling increased. A similar trend was observed in changes of octacosanol and squalene.

In this study, we analyzed the database for items reported to Korea Food and Drug Administration as for manufactured health/functional food during 2010. There were 183 health functional food products manufactured in domestic having over 2 functional ingredients (hereinafter, combinational health functional food) among total 7319 products. Among 183 products, there were 177 products having over two kinds of functional ingredient and 6 products were over 3 ingredients. The most commonly used functional ingredients in the combinational health functional food were Garcinia cambogia extracts which were used in 41 products, Octacosanol and Saw Palmetto extract. When we searched the safety information for the pair of ingredients used in combinational health functional food using several database, there were no reports for safety concern. However, as there are still safety concerns when intake various functional ingredients at once, we suggested to enforce the reporting system of adverse event in order to strength safety management of health functional food. With these complement, the safety management of health functional food might be achieved including a combinational products.

Triticale forage has the highest yield of all winter forage crops, including rye, and a cold tolerance within an average low temperature of -10℃ in January. Therefore, this study analyzed the effects of sowing and harvesting times on the feed value and functional components of triticale to optimize the use and supply of triticale as livestock fee Room temperature' can vary widely with climate, season, and time of day. In order to clearly state the conditions of the study in a manner that facilitates replication by other researchers, please consider using an approximate temperature range instead. Seeds of the triticale 'Joseong' were sown during the fall of 2021 (October 20th) and spring of 2022 (March 7th). The triticale was harvested at the following growth stages: seedling stage, booting stage, heading stage, 10 days after heading, and 20 days after heading. The moisture content of each harvested triticale was adjusted to approximately 60%, and the triticale was fermented for silage for 40 days at ambient temperature under anaerobic conditions. We measured the pH and organic acid content of each silage to determine the feed value and functional component. The lactic acid content of the triticale silage harvested at the seedling stage sown in both fall and spring (1.61%, 1.63%) was the highest among all the silages. The octacosanol content in the silages of both fall-sown and spring-sown triticale harvested at the seedling stage (0.38, 0.27 mg/ml) was the highest. Overall, the results revealed that harvesting time had a greater impact on the feed value and functional components of triticale silage than sowing time.
