  • In this study, three domestic and one foreign formulas for the infants up to 5 month old were examined to detect chemical changes such as pH, reactive sulfhydryl groups(RSH) content, 5-hydroxymethylfurfral(HMF) content, available lysine content, electrophoresis, and surface color caused by heat treatment for long term storage. In the SDS-polyacrylamide gel electrophoresis, A and B products showed similar pattern, while C product had a clearly distinguishable $\beta$-lacto-globulin band, but in casein, only D product showed a few strong casein band. RSH content, which indicate the extent of whey protein denaturation, ranged from 4.40 to 5.93 mmole/g protein. HMF content. which indicate the extent of Maillard reaction, ranged from 192 to 432 $\mu$mole/100g in formulas. B product showed the highest RSH and HMF content. Available lysine content ranged from 31 to 46 mg/g protein. Among them D product contain the highest available lysine content and others showed no significant difference. In conclusion, the domestic infant formulas showed higher RSH and HMF content than the foreign product and the available lysine content of the domestic products were lower than of the foreign product.

  • Cronobacter muytjensii는 유아용 조제분유(IFP)의 잠재적 위험요인으로 중요한 식품 기인성 병원균이다. 이 연구에서는 C. muytjensii 검지를 위한 특이적 면역글로불린 G(IgG)를 개발하고, 이 anti-C. muytjensii IgG를 이용하여 간접 비경쟁 효소면역측정법(INC-ELISA)을 개발하였다. 그 결과, 새롭게 개발한 INC-ELISA 방법은 C. muytjensii에 매우 민감하고, 순수배양 시 $6.5{\times}10^3CFU/ml$의 검출한계와 유아용 조제분유에서 1 cell/25 g의 검출한계를 나타내었다. INC-ELISA 방법은 또한 C. muytjensii에 탁월한 특이성을 보이고, Cronobacter 속 외 11종의 다른 식품 기인성 병원균 계통과의 교차반응을 보이지 않았다. 이러한 결과는, 개발된 INC-ELISA 방법이 C. muytjensii에 매우 민감하고 효율적이며, 신속하고 용이한 검출을 위한 진단 키트 개발에 적용할 수 있음을 시사한다.

  • Protein-energy malnutrition is regarded as one of the public health problems in developing countries as a result of poor feeding practices due to poverty. This study, therefore, aimed at evaluating nutritional quality of a potential weaning food formulated from locally available food materials. The cooking banana fruit(CB) and bambara groundnut seeds(BG) were purchased from local market in Akure, Ondo State, Nigeria. The CB and BG were processed into flours, mixed in ratios of 90:10, 80:20, 70:30 and 60:40 and subjected into proximate, sensory and biochemical analyses using standard procedures. Nutrend(a commercial formula) and ogi(corn gruel, a traditional weaning food) were used as control. The nutritient composition(g/100 g) of the food samples were ranged as follows: moisture 2.94-6.94, protein 7.02-16.0, ash 1.76-2.99, fat 0.76-8.45, fibre 1.52-3.75, carbohydrate 63.84-88.43 and energy 1569.8-1665.7 kcal. The biological value(BV), net protein retention(NPR), protein efficiency ratio(PER) and feed efficiency ratio(FER) of the experimental food samples were significantly(p<0.05) lower than nutrend, but higher than ogi. The haematological variables of rats fed with formulated food samples, commercial formula(nutrend) and traditional weaning food(ogi) were not significantly(p>0.05) influenced by the dietary treatment. However, the values obtained for red blood cell(RBC), white blood cell(WBC), pack cell volume(PCV) and erythrocyte sedimentation rate(ESR) were higher in the experimental food samples than the commercial food. The growth rate of animals fed with experimental food samples were lower than those fed with the nutrend, but higher than those fed with ogi. In conclusion, the nutritional quality of CB and fermented BG mix of 60:40 ratio was better than ogi; and comparable to the nutrend. This implies that it can be used to replace low quality traditional weaning food and the expensive commercial weaning formula.

  • The storage stability of the developed Formula of infant foods was investigated. The results are summarized as follows : When formula A and B were stored at room temperature and refrigeration temperature, there was no remarkable changes in consistency. In frozen state, formula A showed more stability in consistency than formula B and formula A could be stored for 6 months without problems due to retrogradation of starch. The heat treatment of both A and B resulted in the increase of a-value, while L-and b-value showed no such change. But from the 4th month at room temperature, and 5th to 6th month at refrigeration appeared an increase in a -value, hence the browning reaction, while frozen samples did not show noticeable changes in surface color. The heat treatment also caused an increase in POV on both formula. The extent of changes in POV during storage varied with storage temperatures and samples.

  • This research was conducted to survey the feeding methods of Korean women. The survey was executed for 355 mothers bringing up a child below 24 months in some part of Seoul in Korea from April to May, 1990. Incidence of breast feeding was 29.1% of the interviewed mothers in Seoul, which showed lower percentages than those of previous surveys. This research proved the major influencing factor generally depended on its mother rather than babies or labor condition. For example, the higher income and the higher educational degree of its mothers, they tended to prefer the bottle feeding to the others. Generally mothers knew the informations of infant nutrition very well, 84.5% of the interviewed mothers in Seoul had the opinion of 'breast feeding is better', but their knowledge actually didn't work. The source of mothers‘ informations on the infant nutrition showed the books and magazines, friend and relatives, grandmother were many by the order. But there were some discrepancies between the actual and needed source of information; i.e. mothers in Seoul mostly(44.8%) wanted to acquire their informations from mass communications. The reason of breast feeding showed 'for baby's health' was the greatest, and then 'immunity of breast milk' and 'baby's emotion' were great by the order, and the reason of bottle feeding showed 'not enough breast milk' was the greatest. There were no problems in feeding attitude and position of breast feeding, but there were problems in feeding volume, consistency of formula milk and feeding position of bottle feeding.

  • This study was carried out to investigate the lactation and weaning practice of infants and their mothers' attitude on infant nutrition. We interviewed 152 mothers in three pediatric clinics located in Sokcho city. From this survey, $76.3\%$ of infants was fed colostrum milk during first one week of life. During the first 4 months, $31.6\%$ of infants was fed breast-milk, while $42.8\%$ of them was fed bottled-milk. More housewives fed their babies with breast milk than the working mothers. Infants ate first weaning food at 5.73$\pm$1.86 months of life. Highly educated mothers showed positive response to the questionnaire : Breast-feeding is good for baby but it requires mother's sacrifice, and Breast-feeding may ruin the good shape of mothers. Highly income mothers responded negatively to the statement : Breast-feeding is not a must for infants since bottled-milk is a good substitution for breast-milk. Comparing with the mothers whose income was about 1 -2 million won per month, with ones who got paid less than 1 million won per month the former responded positively to : Breast-feeding is good for baby but it requires mother's sacrifice. Mothers recognized the importance of weaning in the following order : Supply of nutrition, Enforcement of digestion and absorption capability, Variety of taste, Disease prevention, Development of self-reliance, and Development of baby tooth. To improve the infants' nutritional status, education program on infant nutrition should be organized and run for the pregnant and lactating women in obstetrician and pediatric clinics and through the mass media as well.
