Dairy products, including milk, cheese, cream, yogurt, and butter, constitute excellent sources of essential nutrients such as calcium, proteins, and vitamin D; therefore, nutritionists recommend a constant daily dietary intake of dairy products. Packaging is an important feature that ensures high-quality products are delivered to consumers; different packaging materials and forms are required depending on the products. Packaging forms include pouches for butter, cheese, and milk powder; cartons for liquid, frozen, and coagulated milk; packets for pasteurized liquid milk; bottles for milkshakes and other liquid products; and cups for frozen and coagulated products. The increase in mobile lifestyles among consumers will lead to smaller households and greater preference for convenience, which will promote individual and smaller packaging for dairy products. This article reviews the development of packaging materials and forms, packaging requirements, and future considerations for the packaging of dairy products.

This study was performed to investigate the relationship between milk consumption, dietary nutrient intake, and physical strength in Korean adolescents for dietary education of home economics subject at middle and high schools. Intake of milk and milk products, that of dietary nutrients, and physical strength records were surveyed for 298 high school students resided in small and medium-sized cities in Korea. Intake of milk and milk products was collected from three-day dietary survey, and daily dairy equivalent of calcium was calculated by dividing daily calcium intake(mg) from milk and milk products by calcium content(200 mg) of 200 mL milk. Dietary survey was performed during three days including two-weekdays and one-weekend by food record method. Dietary nutrient intake was analyzed by CAN-Pro 3.0. Physical strength records were offered from subjects' schools. Subjects were divided into low intake group(${\leq}0.29/d$), medium intake group(0.30-0.78/d) and high intake group(0.79-5.66/d) according to daily mean dairy equivalent of calcium taken by them, and most of them consumed milk and milk products less than '2' of the recommended value. Daily mean dairy equivalent of calcium was significantly related with high records of '50 m running' and 'stand long jump'(p<0.05), however it was not related with other records of physical strength. Intakes of energy, carbohydrate, protein, fat, calcium, phosphorus, iron, zinc, thiamin, riboflavin, niacin and vitamin E were significantly correlated with high record of '50 m running'(p<0.01). Intakes of nutrients were related with '50 m running' except fat were significantly correlated with high record of 'stand long jump'(p<0.05). Intakes of protein, phosphorus, iron, zinc, vitamin A, $B_6$ and E were significantly correlated with high record of 'long distance running'(p<0.05). In conclusion intake of milk and milk products was related with physical strength records('50 m running' and 'stand long jump') and intakes of most nutrients including energy nutrient, vitamin and mineral were correlated with physical strength records('50 m running', 'stand long jump' and 'long distance running') in Korean adolescents. Therefore, optimal consumption of milk and various nutrients for balanced nutrition during adolescents should be emphasized in dietary education of home economics subject for their strong physical strength.

Purpose: The purpose of this study is to explore the level of bone mineral densities of the femur neck and to identify factors affecting bone mineral density of the femur in Parkinson's disease (PD) patients. Methods: Participants were 121 PD patients visiting the outpatient clinic of D University Hospital in B City. Bone mineral density was measured at the femur neck by using a dual-energy x-ray absorptiometry. The serum vitamin D level, the amounts of milk intake, caffeine intake, cigaret smoking, and alcohol consumption, and the number of steps taken daily were measured. Past and present disease history, the medication history, and duration of the disease were also collected. The level of disability was obtained by neurologists using the Hoehn and Yahr stage and the Unified Parkinson's Disease Rating Scale. Results: Among PD patients, 57% had osteopenia and 15.7% had osteoporosis. The bone mineral density of the femur was associated with weight, serum vitamin D level, age, and working status. Conclusion: The identification of weight and serum vitamin D level as important predictive factors emphasizes the importance of balanced nutrition for PD patients.

Purpose: Neonatal late-onset hypocalcemia is defined as hypocalcemia developed after postnatal 3 days and associated with hypoparathyroidism, high phosphate diets and vitamin D deficiency. We experienced the increment of neonatal late onset hypocalcemia over 1 year. We tried to evaluate the relationship between late onset hypocalcemia and maternal hypovitaminosis D. Methods: The medical records in the neonates with late-onset hypocalcemia during January 2007 to July 2008 were retrospectively reviewed. Among those patients, 17 paired sera of mothers and neonates had collected. The levels of 25-OH vitamin D (25OHD) and intact parathyroid hormone (iPTH) were measured and were compared with neonate and the mother. Results: The mean gestational age was $38^{+1}$ weeks, and the mean body weight was 2,980 g. The onset time of hypocalcemia was 5.9 days of age. Most of them (88.2%) were feeding with formula and no one was only breast milk feeding. Of the 17 patients, 13 were born in spring or in winter. The median levels of calcium, phosphorus, alkaline phosphatase, iPTH and 25OHD were 7.0 mg/dL, 8.6 mg/dL, 191.0 U/L, 57.2 pg/mL and 24.0 ng/mL in neonates. The levels of 25OHD of 6 neonates were <20 ng/mL. A total of 16 mothers were considered vitamin D-deficient (<20 ng/mL), and vitamin D insufficient (20<25OHD<30 ng/mL). Conclusion: Neonatal late-onset hypocalcemia in our study seems to be influenced by maternal vitamin D deficiency and insufficiency. Sun tanning and vitamin D supplements from winter to spring would be helpful to prevent maternal vitamin D deficiency, one of the causes of neonatal late-onset hypocalcemia.

This study was conducted to investigate both fat-soluble and water-soluble vitamin contents of commercial powdered infant formula for obtaining basic data on infant nutrition. Ten commercial infant formula based on cow's milk were collected and the contents of fat-soluble vitamins (vitamin A, D, E, K) and water-soluble vitamins (vitamin C, thiamin, riboflavin, niacin, $B_6$, folate, $B_{12}$, pantothenic acid, biotin) were compared with Dietary Reference Intakes for Koreans (KDRIs). The overall vitamin contents in 100 g and in 100 kcal of infant formula satisfied the recommended formula regulation (KDRIs) and Codex. In infant formula during 0-5 monthly age, fat-soluble vitamin A, D, E, K could supply 178.6%, 205.3%, 208.4%, 976.3% of adequate daily vitamin intakes, respectively. Water soluble vitamins, vitamin C, thiamin, riboflavin, niacin, $B_6$, folate, $B_{12}$, pantothenic acid, biotin could supply 173.2%, 237.2%, 269.8%, 295.9%, 431.6%, 165.8%, 1186.3%, 203.8%, 408.3% of adequate daily vitamin intakes, respectively. In infant formula during 6-11 monthly age, all vitamins satisfied their adequate daily intakes as well. Vitamin A, D, E, K supplied 199.2%, 262.3%, 220.5%, 626.46% of adequate daily vitamin intakes. Vitamin C, thiamin, riboflavin, niacin, $B_6$, folate, $B_{12}$, pantothenic acid, biotin could supply 179.5%, 210.2%, 264.7%, 241.5%, 206.0%, 166.9%, 699.5%, 247.0%, 475.0% of adequate intake of KDRIs. From this study, evaluation of vitamin contents of commercial infant formula was established, which could strengthen the basic information on infant nutrition.

Cow's milk and dairy products are elements of the human diet that could play an important role in improving human health. The macronutrients and micronutrients found in milk could supply the nutrients required to maintain human health. Among them, milk-derived bioactive peptides have been identified as potential ingredients found in health promoting functional foods. These bioactive peptides target diet-related chronic diseases, particularly non-communicable ones such as cardiovascular disease, diabetes and obesity. Additionally probiotics such as lactic acid bacteria (LAB) are can be considered live microorganisms that confer health benefits for the host-, when administered in adequate amounts. Further, the calcium, vitamin D, and protein content of milk and dairy products could play a role in proving bone health. The effect of milk and calcium on bone mineral density could prevent against fracture, osteoporosis and rickets. Furthermore, milk and dairy products also contain which factors that, which protect against dental caries (anti-cariogenic properties). This paper reviews the various nutritional functions of milk and dairy products in improving human health.

The present investigation was designed to determine whether supplementation of different level of vitamin E for 12 months to arsenic exposed goats (50 ppm as sodium arsenite) affords protection against the blood hemato-biochemical parameters caused by the metalloid. A total of 24 crossbred (Alpine${\times}$Beetal) lactating goats were assigned randomly into 4 equal groups (control, $T_1$, $T_2$ and $T_3$) of 6 in each, on the basis of average body weight ($36.10{\pm}0.11$ kg) and milk yield ($1.61{\pm}0.04$ kg/d). The animals in $T_1$, $T_2$ and $T_3$ were given 50 ppm arsenic, while in $T_2$ and $T_3$, additionally; vitamin E at the rate of 100 IU and 150 IU/kg dry matter (DM) respectively was additionally supplemented for the period of 12 months. Hemoglobin (Hb), total leukocyte (TLC) and blood lymphocyte % were decreased (p<0.05) in arsenic fed groups and vitamin E supplementation in the experimental group showed a protective potential. Significant increases (p<0.05) in aspertate transaminase (AST) and alanine transaminase (ALT) activities among arsenic supplemented groups were recorded, however vitamin E supplementation at higher doses showed a protective effect (p<0.05) against AST but in the case of ALT no ameliorating effect was found in either of the doses. Plasma total protein was decreased (p>0.05) but creatinine level was periodically increased in all As supplemented groups and vitamin E supplementation did not produce any protective effect. It can be concluded that arsenic exposure resulted in varying degree of changes in hemato-biochemical parameters and activities of antioxidant enzymes in goats but concomitant treatment with Vitamin E is partially helpful in reducing the burden of arsenic induced effect.
