전세계 많은 나라들은 조제분유를 특수 영양식품으로 분류하여 관리에 각별히 신경을 쓰고 있으며, CODEX에서는 첨가되는 거의 모든 성분을 모유에 들어 있는 것이어야 하며, 또한 과학적으로 안전성이 입증된 것만을 넣을 수 있도록 규정하고 있다. 이 때문에 분유 메이커들은 제품 개발을 위해 많은 모유 및 우유 성분에 관한 연구를 바탕으로 하여 모유의 조성에 맞추는 노력을 하고 있다. 국내산 분유는 외국 제품에 비해 면역 기능 향상, 항-알레르기 능력 향상, 뇌와 소화기관의 발달 등을 돕는 성분이 강화되어 있다. 현재 생명과학기술의 진보와 각종 신기술의 도입으로 모유 및 우유속의 극미량 성분까지 분리 정제가 가능함에 따라 다양한 기능성을 갖는 성분들이 상품화되고 있으며, 이를 이용해 조제분유를 개발하고 있다. 두뇌 발달 성분인 DHA, 아라키돈산 등과 면역기능 강화 성분인 뉴클레오타이드, 락토페린 등의 첨가 및 정장기능을 보이는 올리고당 등의 성분강화에서 이제는 뼈 성장 ${\cdot}$ 발달인자, 아토피 및 알레르기의 감소를 위해 가수분해물의 이용 등의 기능을 보강한 다양한 제품이 개발되어지고 있는 중이다.

The fatty acid composition of Phospholipids from human mature milk, modified milk formula and market milk were analyzed by gas-liquid chromatography. The levels of 8:0, 10:0, 19:0, 20:0 and 22:0 were significantly higher in modified milk formula than in human milk. The levels of 14:0 and 16:0 were significantly lower in modified milk formula than in human milk. Modified milk formula had a higher $18:2{\omega}6$ content than human milk (17.9 versus 7.9%). The metabolites of the ${\omega}$9-, ${\omega}$6-$ and ${\omega}$3-series showed lower levels in modified milk formula than in human milk. The fatty acid composition of phospholipids from modified milk formula was similar to that of market milk.

Contents of scorched particles in infant formula were studied to provide a scientific evidence for standardization of Food Regulation in Korea. The specification of scorched particles in infant formula in Korea was satisfied with CODEX, USDA and so on. But food regulations for scorched particles in baby food are not mentioned in Korea. Nowadays social interests of scorched particles in infant formula are being increased in the respect of safety for baby food. The composition and contents of scorched particles were analyzed with Scanning Electron Microscope-Energy Dispersive X-ray Spectrometer(SEM-EDS) and Inductively Coupled Plasma Mass Spectrometer(ICP-MS). The results indicate that the scorched particles consist Ca, Na, Fe, Mg and trace elements derived from the ingredient of infant formula. Infant formula are composed of milk, skimmed milk, whey, mixed vegetable oils, minerals and vitamins. These results also show that the contents of scorched particles of infant formula in Korea are little or similar level to those reported in other countries. In general, heavy metals derived from scorched particle are originally used as a source of minerals in infant formula. And it has been thought that they doesn't effect on Provisional Tolerable Weekly Intake set by FAO/WHO for contents and composition of scorched particles.

The fatty acid composition acyl carbon atoms and species of triglycerides from human mature milk, infant formulas (modified milk formula) and market milk were determined by argentation thin-lager and gas-liquid chromatography. Short-chain fatty acids which sere not detected in human milk were present in very small amount in modified milk formula and market milk. The levels for 5:0, 22:0 and 24:0 in modified milk formula and for 8:0, 10:0, 18:0, 22:0 and 24:0 in market milk were significantly higher than those in human milk. The levels for 10:0 and 14:0 in modified milk formula and for 12:0 and 20:0 in market milk were significantly lower than those in human milk. The relative percent of $18:2{\omega}6$ in human milk, modified milk formula and market milk were on average 12.0, 15.0 and 3.8 percents respectively. Human milk contained significantly higher proportions of both ${\omega}6-and{\omega}3-derived$ long chain polyunsaturated fatty acids than modified milk formula and market milk. The major triglycerides of human milk, modified milk formula and market milk made by the glycerides with 44-52, 50-54 and 36-40 acyl carbon atoms, respectively. There were significant differences in levels for total number of acyl carbon atoms per glycerid molecule of human milk, modified milk formula and market milk. In comparison with human milk, modified milk formula and market milk showed significantly higher levels for saturates but significantly lower levels for trienes to polyenes.

Three-hundred samples of powdered infant formula milk and related products from four different manufacturers in 2010 were collected and surveyed their contaminations for aerobic bacteria, coliform, Enterobacter(Cronobacter) sakazakii, and food-borne pathogens. Fifteen samples of sterilized infant formula milk were all negative on these microorganisms. In all collected products of un sterilized infant formulas and follow-on infant formulas, aerobic bacteria were detected at 239 (83.9%) among 285 samples, and they all were found below $10^3$ cfu/g. Coliform bacteria were also detected at four among 285 samples. Salmonella spp. and Ent. sakazakii, weren't detected at the all samples. Bacillus cereus was detected at 24 (8.4%) among 285 samples. The level of B. cereus was below 100 cfu/g but it was suitable for the range of specification of B. cereus in infant formulas. Clostridium perjringens, Escherichia coli O157:H7, Staphylococcus aureus and Listeria monocytogenes weren't also detected. In consequence, it was suitable for total viable count, coliform and potential pathogen to the specification of infant formulas and related products.

Yogurt was prepared with different substitution ratio [10, 20, 30, and 50% (w/w)] of skim milk with enzymatically saccharified Korean rice wine lees powder (eKRWLP) and fermented with commercially available mixed lactic acid bacteria (Bifidobacterium longum, Lactobacillus acidophilus, Streptococcus thermophilus) at $40^{\circ}C$ for 18 h. Fermentation characteristics were evaluated in terms of acid production (pH and titratable acidity) and viable cell counts of lactic acid bacteria. The pH of yogurts decreased with increasing eKRWLP substitution ratio of skim milk. After 12 h fermentation, titratable acidities of eKRWLP substitution and control (yogurt made without eKRWLP) were 0.84~1.04% and 0.93%, respectively. The titratable acidities of yogurts prepared with 10 and 20% substitution ratio increased than that of the control yogurt, but titratable acidities of yogurts of 30 and 50% substitution ratio decreased. After 9 h fermentation, the number of viable lactic acid bacterial cell were increased to 8.18~8.24 log CFU/g in all yogurts. In sensory evaluation, there were similar preference for eKRWLP yogurts prepared with 10 and 20% substitution ratio and the control. When eKRWLP substitution and control yogurts fermented for 9 h were incubated at $4^{\circ}C$, their pHs and titratable acidities were slightly changed but the number of viable lactic acid bacteria were well maintained above $10^7CFU/g$ for 11 days in yogurts prepared with 10 and 20% substitution ratio among eKRWLP substitution yogurts. These results suggest that eKRWLP can be used as substituent of skim milk and the optimum substitution ratio is around 10~20%.

The lipid and fatty acid compositions and vitamin E content were analyzed in 48 human mature milk, 3 infant formulas (modified milk powder) and 8 market milk samples. The total lipid content in modified milk powder was similar those in human milk and market milk when total solids content of modified milk powder was corrected to that of human milk. In comparison with human milk, modified milk powder contained a lower proportion of triglycerides and higher proportions of phospholipids, free fatty acids and cholesterol esters. The ratios of phospholipids/triglycerides, total cholesterol / triglycerides and total tocopherol/total lipids in modified milk powder were significantly higher than those in human milk and market milk. The American recommendation for linoleic acid (0.7 IU/g) could be satisfied with human milk, modified milk powder and market milk. The proportions of short- and medium-chain even numbered saturates were higher and the proportions of long-chain derivatives of linoleic (${\omega}6$ series) and linolenic (${\omega}3$ series)acids were lower in modified milk powder and market milk than in human milk. It is concluded that in view of their levels in breast milk, the polyenoic derivatives of linoleic and linolenic acids must be taken into account when assessing infant foods.

The present studies were carried out to observe the nutritional effects of three kinds of locally produced dried infantile formula milk (DFM) and one fermented milk (FM). A feeding trial with 60 male growing albino rats weighing $60{\sim}70$ grams was conducted during 6 weeks to compare the nutritive values and protein qualities of three DFM and a FM. The diet treatments consisted of 100% control diet, 70% control diet plus 30% DFM-A, 70% control diet plus 30% DFM-B, 70% control diet plus 30% DFM-C, 100% control diet with FM and 70% control diet plus 30% DFM-B with FM. The items investigated were body weight gain, feed intake, feed efficiency ratio (FER), various organ weights, protein efficiency ratio (PER), digestibility of nutrients, biological value, utilizability of protein and intestinal microbial changes of albino rats. The results obtained are summarized as follows; 1. Although there was no statistical significance, rats fed diets containing DFMs and FM gained faster than the rats fed control diet. The best growth rate was obtained with the DFM-A and DFM-C groups. In spite of the lower protein contents of the three DFM diets than the control diet, the growth rate of albino rats fed the DFM diets was somewhat improved than rats fed control diet. 2. No statistical significance was found in feed consumption but the trend was that the feed intake of control group was higher than those of the DFM diet group. 3. Feed efficiency was inproved significantly (p<0.01) by feeding DFMs as compared with control diet. DFM-A group showed the best FER, although no statistical significance was found. 4. Rats fed the DFM diets showed significantly (p<0.01) higher PER as compared with those of the control group. But no difference was found anions DFM groups. The significant improvement (p<0.01) of PER due also to the feeding of FM was seemed to be brought about by the beneficial effect of FM. 5. The present data revealed that feeding DFM and FM didn't affect the weights of various organs of rats. 6. The protein digestibility of experimental diets was similar to each other. Although no statistical significance was found among treatments, the DFMs and FM surely tended to improve the biological value and utilizability of protein. 7. Microbial study indicated that among intestinal flora FM fed group, there were more Lactic acid bacteria than E. coli. From the experimental results described above, it may be concluded that the nutritive effects of three kinds of locally produced DFMs are much alike and the growth rate of growing albino rats can be improved by feeding either DFM or FM due to their beneficial effects on the feed efficiency and protein utilization.

This study has been concerned with the possibility of delactosed nonfat dry milk(DENFDM, lactose 4.25％) formation into conventional imitation processed cheese(IPC). The effect of DENFDM was mainly a contribution to fracturability, elasticity and gumminess, while hardness and cohesiveness were decreased. Similarly calcium caseinate and sodium caseinate were contributing to cohesiveness, hardness, elasticity and gumminess. Delactosed NFDM has a potential beneficial effect as a partial replacement of caseinate in the formation of the imitation processed cheese to characteristics close to commercial processed cheese.
