Microstructure of milk powder and cheese made from milk powder were observed by electron microscope. Freeze dried milk powder showed apple-like appearance. The cheese made from freeze dried milk powder had relatively flat surface and homogenous deposit in compare with classical processed cheese. Imported milk powder also indicated similar surface as well as freeze dried milk powder, however, the cheese made from imported milk powder had somewhat coarse surface structures with the spaces between casein matrix and deposit. Commericial milk powder showed irregular shape in size and coagulum which were possibly denatured in the course of drying. The cheese made from commercial powder indicted irregular and small deposit and porous structure. The porousity of the cheese seemed to be influenced by the degree of heat treatment. Denatured protein would be less dispersive than native in presence of polyphosphates. Fat globule and protein micelle of cheese made from skim milk powder get very adjacent to each other and showed compactness of micelles. It is thought that melting mechanism of skim milk powder was different from the melting of typical processed cheese.

Milk powders were made by several drying methods and raw materials, and rheological properties of milk powders were investigated by an Instron Universial Testing Machine. The results obtained are summarised as follows. Bulk density of the drum dried whole milk powder was $0.382\;g/cm^3$ and was higher than that of other milk powders. The Hausner ratio, angle of repose and compressibility of the spray dried skim milk powder were 1.127, $32.5^{\circ}$ and 0.029 respectively. This result indicated that skim milk powder showed free flowing characterristics. The compressibility of the drum dried whole milk powder was decreased by the decrease of moisture content. Compressibility of the milk granule was 0.056 and was lower than that of milk powder. The spray dried milk powder of a grobular shape had higher solidity than the freeze or drum dried milk powder. The drum dried milk powder particles consist of irregular shape.

Oxidative stabilities of fat in DHA(cis-4,7,10,13,16,19-docosahexaenoic acid)-added dry milk and ordinary dry milk during storage were studied by determining thiobarbituric acid values of samples. Two kinds of milk powder samples were purchased in the local supermarket and $2{\pm}0.05\;g$ of samples were transferred into serum bottles, which were stored under the light or under dark The oxidation of fat in DHA-added milk powder was higher than that of fat in ordinary milk powder and the acceleration was more evident in the presence of light Light and unsaturated fats accelerated synergistically oxidation of milk fat Addition of DABCO(diazabicyclooctane), which is an efficient singlet oxygen quencher, significantly decreased the photooxidation of milk fat This result clearly suggested that singlet oxygen oxidation (Type II reaction) was involved in the system. Deceleration of milk fat oxidation by DABCO was higher in the DHA-added milk powder.

30명의 건강한 유아를 세 그룹으로 나누어 팔미틴산을 포함한 주요 지방산의 조성을 모유에 맞춘 조제분유 A, 팔미틴산의 비율을 모유의 1/3으로 조절한 조제분유 B, 그리고 모유와 조제분유 B를 약1:1 비율로 각각 1주일간 섭취하도록 하여 그들의 변을 수거, 분석을 하였다. 변의 농도, 횟수 및 변의 색에 있어서는 세 그룹 모두 유의할만한 차이를 관찰할 수 없었으나, 팔미틴산을 포함한 포화지방산과 칼슘, 마그네슘, 철분의 흡수는 혼합수유한 그룹이 가장 높았으며 조제분유 A를 섭취한 그룹에서 가장 낮았다. 또한 조제분유 B를 섭취한 그룹의 경우 혼합수유그룹에 비해 다소 낮은 흡수를 보이긴 하였으나 조제분유 A를 섭취한 그룹과는 현격한 차이를 보였다. 모유의 대표적인 포화지방산인 팔미틴산의 조성을 낮춘 조제분유를 수유할 경우 장내 지방산의 흡수를 개선하였으며 미네랄의 흡수도 효과적이었다.

This study was carried out in order to investigate the effect of additives on Jeungpyun (fermented and steamed rice cake) Preparation. Soy bean flour, whole milk Powder, skim milk Powder, egg yolk, egg white, and mugwort were added in the Preparation of Jeungpyun. There were not significantly difference in loaf volume between control and experimental groups addfd egg yolk, egg white and mugwort. In sensory evaluation, the hardness of Jeungpyun containing of soy bean flour, milk Powder, and egg were lower than control The Jeungpyun containing mugwort was more bitter and harder than the control. The rheological properties measured by texturometer were significantly different among the Jeungpyun added with different kinds of additives. The hardness was significantly lower in Jeungpyun containing whole milk Powder and soy bean flour and springiness was higher in mugwort Jeungpyun compared with the control. In 4$^{\circ}C$ storage, retrogradation of Jeungpyun assessed from hardness measured by texturometer was delayed by addition of soy bean flour and whole milk powder.

아이를 처음 낳는 부모님들은 신생아의 분유를 타는 방법을 모르거나 넣어야 하는 분유의 양을 잘못 넣는 경우가 많다. 분유를 타는 방법은 신생아의 개월 수 마다 물의 양과 분유의 양도 다를 뿐더러 신생아에게 먹일 수 있는 적당한 온도도 맞춰야 하는 어려움이 발생한다. 하지만 분유 타기에 미숙한 부모나 외출을 하는 경우 물의 온도를 맞추는 것은 번거로움과 어려움을 발생시킨다. 이러한 문제점들을 해결하기 위해서 본 논문에서는 아두이노(Arduino)와 소프트웨어를 결합하여서 신생아들에게 분유를 타줄 때 편리하게 사용할 수 있는 스마트 젖병을 설계하고 구현하였다.

The sensory and instrumental characteristics of Jeung-pyun made from various additives were investigated to improve the qualify of Jeung pyun and to know the effects of additives on Jeung-pyun preparation. In sensory evaluation of Jeung-pyun made from various additives, hardness was significantly lower by addition of soy bean flour, whole milk powder, and egg yolk. The cell uniformity of Jeung-pyun was significantly lower by addition of egg yolk and mugwort. And the dgree of bitterness Jeung-pyun containing soy bean flour and mugwort flour were significantly higher than that of control. Retrogradation of Jeung-pyun assessed from DSC thermogram and hardness measured by texturometer was delayed by addition of soy bean flour, and whole milk powder.

Infant formula is one of the main nutritional sources for infants. In this study, the fatty acid compositions of Korean (domestic, n=8) and foreign infant formulas (n=3) were analyzed. Crude fats were extracted using the Folch method, and fatty acid compositions (total and positional) were analyzed by gas chromatography. In the fatty acid compositions of infant formulas, oleic (19.88~44.64%), palmitic (7.59~21.65%) and linoleic acids (16.72~25.87%) were the major fatty acids. Domestic infant formula products contained 35.94~56.55% total saturated fatty acid content, whereas that of foreign infant formula ranged from 34.40~42.88%. The content of monounsaturated fatty acids ranged from 20.23~44.99% in domestic products and 34.11~45.07% in foreign products. In addition, 0.17~2.57% arachidonic acid/docosahexaenoic acid and 10~13% linoleic acid/linolenic acid were detected in the analyzed products (domestic and foreign products). A small amount of trans fatty acids (0.25~1.69%) were found. In sn-2 position analysis, palmitic acids (1.84~38.74%) were detected in the analyzed formulas. Further, typical triacylglycerols in human milk, including 1,3-di-monounsaturated-2-saturated triacylglycerol, were not detected in the analyzed formulas.

Soy milk prepared from soy protein concentrate was added with each of four types of milk products. Acid production and growth of five species of lactic acid bacteria(LAB) in soy milk and sensory property of soy yogurt were investigated. Acid production by LAB increased in proportion to concentration of milk products added to soy milk. Among the four milk products tested, whey powder or skim milk powder stimulated acid production by LAB more than whole milk powder or modified milk powder. Stimulating effect by whey powder on acid production by LAB was greater than other milk products at low concentration. Acid production by LAB in soy milk added with glucose or milk products significantly increased during fermentation. Sensory property of soy yogurt added with whole milk powder or skim milk powder was better than that of reference (soy yogurt added with glucose) while sensory property of soy yogurt added with whey powder or modified milk powder was Inferior to that of reference.
