대표 농산물 섭취에 따른 친환경유기농자재 rotenone의 노출량 위해성 평가를 위하여 총식이조사(Total Diet Study, TDS)자료를 바탕으로 선정한 대표 농산물인 상추 및 오이에 포장시험을 통한 잔류량을 분석하였다. 상추, 오이의 rotenone 오염도를 확인하기 위해 잔류성 시험결과를 토대로 rotenone의 잔류 모니터링을 실시한 결과, upper bound (UB) 적용 시 평균 0.00~0.68 mg/kg 이었으며, lower bound (LB) 적용 시 평균 0.00~0.45 mg/kg이었다. 전체인구집단에서 평균오염도의 상추, 오이 섭취를 통한 rotenone 위해도는 UB의 경우 0.00~18.41%이었고, LB의 경우 0.00~12.19%로 매우 낮은 수준으로 나타났다. We report the dietary exposure to rotenone in the Korean population and children (1-18) through consumption of lettuce and cucumber. To obtain the residue data, we analyzed using the GC-NPD and HPLCDAD method. Rotenone residues in samples were as follows; lettuce 0.16-1.15, cucumber < 0.001-0.006. The average dietary intake was determined using result from the 2009 Korea National Health and Nutrition Examination Survey Data. The risk index (RI) was calculated using rotenone residues and dietary intakes. The lettuce and cucumber showed the highest at 18.41%, 0.00, respectively. RI fell below 100 of %RfD showing no risks in these vegetables. Therefore, the risk assessment on the detected rotenone was evaluated as safe level.
Due to a variety of food products to choose from with accessibility of ample nutrients as a result of industrialization and economic development, there is a widespread concern of hyper- nutrition. However, daily intake of certain nutrients are still not on bar with the recommended daily intake, which ultimately leads to the unbalanced nutrient diet in people’s dietary life. The average daily intake of calcium per person is 503.0㎎, which is 70% of the recommended nutrient intake (RNI), and for males between the ages of 19 to 29, the RNI is 750㎎, but the average intake is at 83% of the RNI with 643.0㎎. Milk is a perfect food, which contains almost all nutrients that keeps the human body healthy. Calcium in milk, especially, when compared to other sources of calcium, has up to 7 times the body utilization, and whey proteins such as lactose and casein helps the body absorb calcium. This supports the fact that to prevent male osteoporosis, military personnel drinks milk at least once a day to supplement calcium. Also, drinking milk or ingesting dairy products may reduce the risk of obesity. Adequate calcium intake also helps maintain a normal range blood pressure. There is a study, which shows that increase in calcium intake, increases sodium excretion, which, in turn, suppresses the increase in blood pressure. Korean military personnel is made up of ages from 19 to 29, which is the optimum period to store calcium in the bones for old age. Ingesting adequate amount of milk or any dairy products at least once a day maximizes bone density and helps maintain it for a longer period of time. Also, milk intake for military personnel with obesity or insulin resistance syndrome may help improve obesity and decrease the risk of high blood pressure. Calcium supplement through milk with the low-sodium diet implemented in the military meal plans can be said to be a crucial factor in increasing strength and stamina of military personnel and improving their combat power.
Over the past decade, there has been growing scientific evidence that dietary milk plays a role in beneficial effects for human health. Milk provides a number of good ingredients, in particular with growth factors and different types of proteins such as α -lactalbumin and β-casein. As well as essential amino acids of leucine and isoleucine are make to a positive way of human physical conditions. Therefore, those ingredients are directly involved in the human body, fluid composition and involved in metabolism of protein or carbohydrate. In addition, the development of physical strength and bone health associated with milk consumption. Thus, milk is one of good food for prevention of osteoporosis. Nowadays, several dietary guidelines suggest that people should intake two or three cups of dairy products including milk a day. However, some people cannot drink milk because they appear many adverse effects with regard to intake of milk like allergic reactions, lactose intolerance and weight gain problem. Consequently, it is worthy to discuss about these matters. Person pose the health problems regarding milk consumption should select dairy products carefully. Milk substitutes such as partially-hydrolyzed formula, yogurt, cheese and non- and low-fat dairy products are suggested. They prevent the allergy and lactose intolerance due to lactase in fermented milk digesting the lactose into glucose and galactose. Taking all of these into account, milk consumption is very important to maintain the human health. Although there are several adverse effects with regard to milk consumption, it would not be shown any health problem only if it follows the milk dietary guidelines. Therefore, a milk drinking should be actively encouraged for the public health.
This study was compared the physicochemical properties and sensory properties of Korean high quality rice(Kopoomkyuck) and Japanese Koshihikari rice. Amounts of protein, fat and water were examined to understand the physicochemical properties. Also, sensory properties were examined by cooked rice and evaluated two different kinds on five-point scale in terms of seven categories - color, glossy, flavor, sweet taste, delicate taste, sticky and overall preference. As a result, we found that two groups of physicochemical properties were not much different. However, Japanese Koshihikari rice was found high score especially, color and glossy categories. Therefore, this study showed that sensory categories for Korean rice has better qualities. Furthermore, we suggested that Korean rice markets should make to improve and produce the high quality type of rice in order to make to increase of consumer’s demand because many consumers interest has been decreased which is related with reduced consumption of rice.
