  • 쌀의 소비를 촉진하고 쌀 가공품의 하나인 쌀 물엿을 이용한 고추장 제조를 시도한 결과 수부함량, pH 및 적정산도는 쌀 물엿 고추장과 쌀가루 고추장 사이에 큰 차이를 보이지 않았다. 환원당은 쌀 물엿 고추장이 쌀가루 고추장에 비하여 높았으며, 담금 초기에 비하여 숙성 90일에는 두 시험구 사이의 차이는 줄어들었다. 아미노태질소는 숙성 80일까지는 증가하다가 그 이후에는 두 시험구 모두 감소하였다. 색도 측정 결과 쌀가루 고추장의 L값이 쌀 물엿 고추장에 비하여 높게 나타났다.

  • This study was conducted to identify the optimum cooking method and the ideal composition of Wax gourd Jung Kwa for the purpose of wide distribution. Wax gourd Jung Kwa was made by peeling off the wax gourd, digging out the stuff, slicing, soaking the pieces in ash water, and boiling slightly, then boiling down in honey, grain syrup. sugar, etc. As a result of sensory evaluation, the best color of Jung Kwa was observed in the recipe of pretreated wax gourd 300g, water 1 litre and grain syrup 495$m\ell$; for the flavor, hardness and chewiness, Pretreated wax gourd 300g, water 1 litre, corn syrup 475$m\ell$ and sugar 70g; for the adhesiveness, pretreated wax gourd 300g, water 1 litre and corn syrup 515$m\ell$; for the sweetness, pretreated wax gourd 300g, water 600$m\ell$ and sugar 90g and honey 120g. Overall Qualify was the highest in the recipe of pretreated wax gourd 300g, water 1 litre, com syrup 475$m\ell$ and sugar 70g, of which the sweetness was 74%. There were significant differences in all items (P<0.05). For mechanical characteristics, the maximum cutting force was the highest in the samples with the recipe of pretreated wax gourd 300g, water 1 litre, corn syrup 475$m\ell$ and sugar 70g, and there were significant differences among all items (P<0.05). The highest moisture content, 45.54%, was observed in the recipe of pretreated wax gourd 300g. water 1 litre and corn syrup 475$m\ell$. There were significant differences among all items (P<0.05). The L value(lightness) was the highest in the recipe of pretreated wax gourd 300g, water 1 litre, corn syrup 475 $m\ell$ and sugar 50g. The a value(redness) was the highest in the case of pretreated wax gourd 300g, water 1 litre, com syrup 475$m\ell$ and sugar 70g, which was almost red; and the b value(yellowness), wax gourd 300g, water 1 litre and corn syrup 475g, which gave almost Yellow color. Taking consideration of the above results, the most desirable recipe for wax gourd Jung Kwa was to mix the 300g of pretreated wax gourd with 20g of ash powder, boil them slightly for 2 min, soak them in cold water for 1 hour, and boil them down with 475$m\ell$ of com syrup, 70g of sugar, and 1 litre of water for 5 hours, resulting in the sweetness of 74%. The samples with above recipe were the best in flavor, chewiness and hardness in sensory evaluation, and showed the highest maximum cutting force and nearest red color in the mechanical test.

  • To evaluate the quality difference between rice starch syrup Kochujang (RSSK) and rice flour Kochujang(RFK), moisture content, pH, titrable acidity, reducing sugar, amino nitrogen and color were measured for 90 days. Moisture content was no great difference between samples and was slowly increased during aging. pH of RSSK was 6.03 and that of RFK was 5.94 after mashing. And it was slowly decreased during aging. Titrable acidity was increased with no great difference between RSSK and RFK. Reducing sugar content of RSSK and RFK was 17.0% and 5.8% after mashing respectively. Reducing sugar content was increased till 40 days, but was decreased thereafter. Amino nitrogen content of RSSK was 123.6 mg% and that of RFK was 93.0 mg% after 20 day aging. Lightness of RSSK was higher than that of RFK, but redness was similar between RSSK and RFK.

  • Quality changes of starch syrups were investigated during storage at 20 and $60^{\circ}C$. Color properties such as spectrophotometric properties, HMF and Hunter color value were continuously increased during storage period. And they were largely changed as much as storage temperature and hydrolysis degree were higher. Starch syrups were all showed to flow behaviors as non-Newtonian fluids and increased slightly during storage. And monosaccharide was decreased and di- and oligosaccharide were slightly increased during storage.

  • Changes in intrumental and sensory Theological parameters of chewing gum during storage were stuided. Texture changes are influenced to the great extent by moisture content of stored chewing gum and D.E. of cornsyrup, meanwhile content of cornsyrup, process condition and storage temperature had a little effect on texture change. Highly significant correlation was observed between logarithmic instrumental texture parameters of deformation, bending and puncture test and logarithmic moisture content. And also good correlations were observed between each sensory and instrumental texture parameters. The optimum texture values were estimated by regression analysis.

  • Fish-frames, which are left after obtaining fillets or muscle during fish processing, consists of useful food components, such as muscle, collagen, calcium, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). This study was carried out to prepare snack using conger eel frame (SF) for human consumption and also to elucidate food component characterization of the snack. The results of volatile basic nitrogen suggested that conger eel frame was a suitable material for preparing snack. Based on the results of sensory evaluation and costs, starch syrup was an optimal sweetener for preparing snack using conger eel frame. The starch syrup-treated SF appeared safe because the moisture content and peroxide value were below the safety limits described in the guideline of Korea Food and Drug Administration (KFDA). Starch syrup-treated SF was similar in the pattern of fatty acid composition to soybean oil, whereas EPA and DHA were detected in SF. The total content of amino acid in starch syrup-treated SF was 23.9% based on 100 g of raw material. The maj or amino acids were aspartic acid, glutamic acid, glycine and alanine. The total contents of calcium and phosphorus in starch syrup-treated SF were 4.9% and 2.8%, respectively. The Ca/P of starch syrup-treated SF was 1.9, which is a good ratio for absorption of calcium. The SF made with starch syrup was superior in EPA and DHA compositions, total amino acid, calcium and phosphorus contents to commercial snack using eel frame.

  • As already pointed out increasing the concentration of dried insam with gangjung becomes progressing the antioxidant effect: 1. The antioxidant effect of gangjung with untried insam increased than gangjung and above 6.0% of undried insam is same of the storage stability, 6 months 2. The more increased acid value(AV) and the peroxide value(POV) of susaln gangjung the longer period of storage, but there was no significient difference with the kinds of adding methods. 3. Sensory evaluation of preference for flavor gangjung with increased according to increasing concentration of undried insam but 6.0% undried insam in maltose was the best among samples.
