  • 수획기(1973년 9월$\~$1974년 4월) 중, 참굴의 생패를 채취하고 자숙하여서 얻은 자즙의 식품영양학적가치를 평가하기 위하여 화학포성의 월별 변화를 분석한 결과는 다음과 같다. (1) 조단백태 질소의 양은 1월을 전후하여 약간 감소하였으나, 그 이후는 계속 증가하는 경향이었으며, 이 점은 비단백태 질소에서도 같은 결과이었다. (2) 아미노태 질소는 4월까지 계속 증가하였으며, 특히 2월 이후는 급격히 증가하였다. (3) 총당은 그 대부분이 글리코겐으로 이루어져 있음을 알 수 있었고, 글리코겐은 아미노태 질소의 함량변화와 비슷한 경향으로서 4월까지 계속 증가하였다. (4) 자즙중의 조단백질과 총당의 함량변화는 수분함량과는 역의 상관관계를 보였다.

  • We have gathered a fatty acid to recycle the waste oil of food manufacturing process, and then made a soap from the waste oil by alkali saponification. Effects of the washing elements such as the concentration of the soap, temperature and time were evaluated to find out the optimum washing conditions, and results are as follows. 1. We could find soaps made from the soybean oil (A), corn oil (B), rape seed salad oil (C), cotton seed oil (D) and a soap consisting of the each oil 25% respectively (I) had the lowest surface tension at the concentration of 0.225% -0.25%. Compared with the single fatty-acid soap, the multi-component soap I showed the lower surface tension at the cmc. 2. All the samples of A-I showed the lowest contact angle for the solid material at the concentration of 0.25%. The multi-component soap of I showed higher contact angle than the single.component soaps of A, B, C and D. 3. The soap G, made from the waste oil, show lower surface tension than 5, made from the complex raw fats of the eatable fatty oil acid and H, commercial soap. 4. The washing efficiency depends on the washing time. Especially the 25-minute was found to be the optimum washing time. 5. The highest washing efficiency was found at the 0.25% cont. reagardless of the washing temperature. At 0.15% concentration level the washing efficiency reduces as washing tem- perature increases. At 0.3% concentration level the highest washing efficiency was found between $50^{\circ}$-$60^{\circ}$. 6. The soap made from the waste oil showed the highest washing efficiency in terms of concentration, temperature, and time. 7. The soap made from the waste oil showed the similiar concentration of hydrogen ion to the synthetic detergent. 8. The hand value of the fabric washed by the soap made from the waste oil was a little lower value than those washed by the synthetic detergent.

  • 가공적성을 떨어뜨리지 않으면서 우수한 기능특성을 보이는 식이섬유원은 제조할 목적으로 대량 수급이 용이한 사과쥬스박과 두유박에 작종 이화학적 처리하여 식이성유의 함량과 기능성을 향상시킨 식이섬유원을 이용하여 이들을 직접 식품에 응용하여 그 이용 가능성을 모색하였다. 식이섬유질원을 밀가루와 혼합한 복합분의 호화양상을 Amylograph로 측정한 결과 식이섬유질원의 첨가량이 증가될수록 점도가 감소하였다. 식이섬유질원을 첨가하여 면을 제조하여본 결과 식이섬유질원의 첨가량이 증가할수록 조리면의 중량과 부피는 증가하였으나 인장강도는 감소하였는데 처리 사과육이 처리 두유박보다 인장강도의 감소가 심하였다. 관능검사에서는 처리 두유박 5% 첨가시 밀가루면보다 우수한 관능성을 보였으며 처리 두유박 10%와 처리 사과육 5% 첨가시 향기, 색도, 조직감 및 전체적인 맛에서 밀가루면과 유의차를 보이지 않았다.

  • This experiment was designed to observe some influence on the serum components of growing rats maintained with basal diet supplemented with sausage. Forty male Albino rats were used as the experimental animals and the subjects were divided into four diet groups (control group; feeding of basal diet containing 10.8% and 10.4% of protein and lipid respectively, A group; feeding of sausage containing 12.5% and 27.6% of protein and lipid respectively supplemented with basal diet every day, B group; feeding of sausage supplemented with basal diet once a three-day and C group; feeding of sausage supplemented with basal diet once a five-day) and each group was fed on the corresponding diet for forty-days. The contents of protein, lipid and cholesterol in their serum were determined. The result obtained are summarized as follows: 1) The final body weight and liver weight of the A group were increased more than other groups. 2) The protein contents in the serum of the B group was increased more than other groups. 3) The total lipid contents in the serum of the A group and B group were decreased compared with control group. 4) The total cholesterol, ester form cholesterol and free form cholesterol in the serum of the A group were decreased, but the total cholesterol and ester form cholesterol in that of the C group were increased compared with control group.

  • Crabs are a popular seafood item. However, they can harbor many microorganisms, heavy metals, radioactivity, and benzo(a)pyrene, which are potential health risks to humans. The objective of this study was to assess the potential of swimming crabs for use in foods such as Ganjang-gejang, by measuring their sanitary biological and chemical properties. Viable microbial cell counts in swimming crab samples were $3.4{\times}10^2-6.7{\times}10^4CFU/g$, but no coliform, Escherichia coli, or pathogenic bacteria, such as Vibrio parahaemolyticus, Enterohemorrhagic E. coli, Listeria monocytogenes, Staphylococcus aureus, or Salmonella spp., were detected. Heavy metal concentrations in swimming crab samples were non-detectable to 0.112 mg/kg for total mercury, non-detectable to 0.435 mg/kg for lead, and 0.115-0.836 mg/kg for cadmium. Benzo(a)pyrene concentrations ranged from $0.025-0.060{\mu}g/kg$, and the volatile basic nitrogen content ranged from 8.7-15.6 mg/100 g. No radioactivity was detected in samples. These results suggest that swimming crabs are viable for use in seafood products.

  • In this study, the concentrations of polycyclic aromatic hydrocarbons (PAHs) were investigated in meat process food and for cooking methods (pan-frying and charcoal fire). The methodology involved liquid-liquid extraction, silica gel cartridge clean-up and determination by gas chromatography/mass spectrometry (GC/MS). The recovery of 17 PAHs spiked into these samples ranged from 66.6 % to 98.0% and the coefficient of variation was less than 10%, but that of dibenz(a,h)anthracene was 16.39%. The mean concentration of total PAHs in processed samples was ND~7.2 ng/g, whereas that pan-fried and charcoal-fired samples were ND~22.1 ng/g and, 12.7~367.8 ng/g, respectively. Therefore, the concentrations of total PAHs in cooked samples were higher than in original samples and charcoal-fired samples had the highest total PAH levels.

  • The primary objective of this research was to investigate the recognition, preference and the present using status of yam for the data which will be useful to make consumers intake more yams and to develop more yam processed products. Almost all respondents who had eaten yams liked it, and Andong people eat more yams than Daegu people. About 60.3% respondents who like yams cited the reason was "it's good for health". Among the respondents who had eaten yams recognized it as nutritional, healthful, and diet food compared with the respondents who had not eaten yams. Recognition degree was higher when the preference for yams was higher. Among the types of yam processed cooking, according to intake ratio, yam juice formed 38%, followed by bleaching(17%) etc. Among the types of yam processed food, powdered tea formed 34%, followed by yam gruel(24%), yam drinks(19%) etc. It showed that respondents eat very few foods made from yams and yam processed food. As for purchasing yam processed food, the result showed that the main concerns of the respondents were the "ratio of yams"(24.9%), followed by "tastes"(21.3%) etc. The largest group (29.4%) of the respondents suggested that the improvements of yams were "diversification of the processed food" followed by "improved taste"(26.4%) while 62.5% of the respondents indicated that they would buy yams after its improvement, which showed a good prospect of yam processed food.

  • This study was to investigate consumers' recognition, preference, and use condition of processed food of Prunus mume(PFPM). As for the general recognition of Prunus mume, as the age is higher, and as the group of manufacture and intake has a higher level of academic attainments, the level of recognition is high. The group that manufactures and takes in PFPM at home showed high preference for Prunus mume processed food, and significant differences were shown among groups in this regard. The group of higher age and academic attainment level and those who manufactured Prunus mume at home showed high intake frequency of PFPM. 88.7% of the all respondents said that they had had Prunus mume products such as Prunus mume alcoholic beverage(76.3%), undiluted solution of Prunus mume(74.9%), Prunus mume tea(60.1%), and Prunus mume Jjangajji, or sliced vegetables preserved in soy sauce or hot pepper paste(46.3%). The rates of intake experience on another PFPM were relatively very low, and PFPM consumers in Daegu and Gyeongbuk areas were very limited. As for the prospect of Prunus mume processed food consumption, 48.8% and 46.7% of the respondents expected that it would remain in the current condition and would increase respectively. Moreover, 62.8% of the respondents said that they would purchase new PFPM satisfying such requirements above, which suggests that producing new PFPM is very positive.
