  • pH, proximate analysis and functional properties were not significantly affected by reduced salt levels in NFS which contained 75${\sim}$76% moisture, 14${\sim}$15% protein < 0.5% fat in the final products. However, NFSs had differences in color and EM (%) values as compared to RFS, The results of textural test showed that they were not different with reduced salt levels (0.75${\sim}$1.5%) among the RFS and no-fat treatments (P>0.05). NFS containing 1.0% salt had similar sensory color, flavor and saltiness values to those RFS. These results indicated that NFSs was successfully manufactured with 1.0% salt level and these may contribute to the 'healthier meat products' for consumers due to no-fat and low-salt meat products.

  • Development of crops with high quality as well as various beneficial functions is necessary to satisfy consumers being interested in their health and to enhance a competitiveness in the international market of agricultural products. What we have achieved so far from our research on crop quality was not sufficient since we often neglected sensory feature of crop products such as eating quality but in many cases, we put more emphases on nutrient contents, physico-chemical properties, and out-appearing features of the products. Therefore developments of sensory elements and technique for evaluation with a priority given to eating quality of each of an individual crop are important and very urgent to be solved in Korea. An endeavor to develop bioactive crops is necessary and resonable but aspects of both productivity and economy with a special emphasis on the original purposes such as production of energy and nutrient for human life must be considered. The development of more concrete ideas for crop functionality is essential before any research goes further.

  • Experiments were conducted to assess the quality properties of steamed fish paste by addition level, along with a fish meat replacement(dried bovine plasma). The moisture, crude protein, crude fat and ash contents evidenced partially significant difference among the controls, DBP1, DBP2 and DBP3 groups(p<0.05). The pH values of the steamed samples were higher than those of the non-steamed samples, and when the content of the dried bovine plasma as meat replacement agent was increased, the pH was increased. The water holding capacity of the steamed fish past samples, along with the replacement levels were significantly higher than in the samples without the meat replacer(p<0.05). The range of cooking loss was $5.19{\sim}5.38%$. Structural weakening of the boiled samples was significantly higher than that observed in the fried sample. Hardness and chewiness were increased slightly by the addition of bovine plasma, but gel strength evidenced a pattern of decreased in DBP1, DBP2 and DBP3 groups. The result of our sensory evaluation on taste, texture, color and overall acceptance evidenced significant differences among the controls, DBP1, DBP2 and DBP3 groups, and the sensory score of color was the highest.

  • While attempting to develop low salt, low fat and high fibre chicken nuggets, the effect of partial (40%) common salt substitution and incorporation of chickpea hull flour (CHF) at three different levels viz., 5, 7.5 and 10% (Treatments) in pre-standardized low fat chicken nuggets (Control) were observed. Common salt replacement with salt substitute blend led to a significant decrease in pH, emulsion stability, moisture, ash, hardness, cohesiveness, gumminess and chewiness values while incorporation of CHF in low salt, low fat products resulted in decreased emulsion stability, cooking yield, moisture, protein, ash, color values, however dietary fibre and textural properties were increased (p<0.01). Lipid profile revealed a decrease in total cholesterol and glycolipid contents with the incorporation of CHF (p<0.01). All the sensory attributes except appearance and flavor, remained unaffected with salt replacement, while addition of CHF resulted in lower sensory scores (p<0.01). Among low salt, low fat chicken nuggets with CHF, incorporation CHF at 5% level was found optimum having sensory ratings close to very good. Thus most acceptable low salt, low fat and high fibre chicken nuggets could be developed by a salt replacement blend and addition of 5% CHF.

  • This study was performed to provide scientific information for consumers and to increase the quality and consumption of Sullungtang prepared with bone from Hanwoo. The physico-chemical, sensory, nutritional properties of Sullungtang by different parity were investigated. The extracting extents of blood were significantly higher for heifer among Hanwoo cows with different parity(none, the second or the fourth) and for back bones among different bone portions (round, hind shank, arm, fore shank or back bone) (p〈0.05). For Sullungtang extracted from bones of heifer was higher in collagen contents than those extracted from cows with the second or the fourth parity. Sullungtang extracted from bones of heifer and cows with the second parity had significantly higher contents of condroitin and viscosity than those of cows with the fourth parity, however there was no significant difference between heifer and cows with the second parity. In color, L values were significantly high, and a and b values were significantly low for Sullungtang extracted from bones of heifer when compared to those extracted from the other cows with the second parity. The contents of total nitrogen, sodium, or calcium were higher for Sullungtang extracted from heifer than those from the cows with the second or the fourth parity. In amino acid compositions, the percentages of glycine were highest and proline and glutamic acid were followed fro all Sullungtang samples from Hanwoo. The results showed that the overall quality of Sullungtang significantly decreased as the parity increased for Hanwoo cows. The Sullungtang extracted from bones of heifer had the best sensory scores as well as nutritional quality when compared to those extracted from the cows with parity. Therefore, the labeling and price for cow bones should be differently evaluated by their parity and age in marketing system. 본 연구는 한우뼈로 만든 탕의 품질에 대한 소비자의 요구에 부응하고 한우뼈의 부가가치 향상 및 소비 확대를 위하여 산차별에 따른 이화학적, 관능적 및 영양적 특성을 구명하고자 실시하였다. 산차별에 따른 혈액추출정도는 한우 미경산이 유의적으로 높았으며 (p〈0.05), 부위간 비교에서는 잡뼈가 유의적으로 가장 높았다(p〈0.05). 점도는 미경산과 2산차 간에는 유의성이 없었지만 미경산이 높은 경향을 나타내었다. 콜라겐 함량은 미경산이 유의적으로 높았고(p〈0.05), 콘드로이친황산 함량에서는 미경산이 유의적으로 높았으나(p〈0.05), 2산 차이와 유의성이 인정되지 않았지만 높은 경향을 보였다. 명도에서 미경산 추출물이 높은 경향을 보였고 적색도와 황색도는 미경산이 유의적으로 낮았다(p〈0.05). 관능평가는 미경산이 유의적으로 높게 평가되었다(p〈0.05). 총질소, 나트륨 및 칼슘 함량은 미경산 추출물이 유의적으로 가장 높았다(p〈0.05). 한우암소 추출물의 아미노산 조성중 Glycine이 가장 높았고 다음은 Proline, Glutamic acid 순이었다. 이상의 결과를 종합하여 볼 때 전체적으로 한우 미경산우가 우수하였고 산차가 증가할수록 품질이 떨어지는 것으로 나타나 한우암소뼈를 판매시 산차 및 나이에 따라 가격을 차별화 시키는 것이 바람직할 것으로 사료된다.

  • The optimum level of fresh granulated low-calcium (0.2%) skim milk co-precipitate, as fat substitute in low-fat ground pork patties was determined on the basis of physico-chemical, cooking and sensory properties. Low-fat ground pork patties (<10% total fat), formulated with 15 per cent water, 4 per cent added fat, 1.5 per cent salt and 4-10 per cent milk co-precipitate, were evaluated for proximate composition, cooking characteristics and compared with control patties with 15 % added fat. The moisture and protein content of raw and cooked low-fat patties were significantly (p<0.05) higher than control. The incorporation of milk co-precipitate in low-fat patties improved cooking yield, fat and moisture retention and reduced shrinkage. The sensory properties of low-fat patties were comparable with control patties. The overall acceptability of low-fat patties formulated with 7% milk co-precipitate was significantly (p<0.05) higher than patties with 10% level and non-significantly (p<0.05) higher than low-fat patties containing 4% milk co-precipitate and control. Instrumental Texture Profiles of developed low-fat patties and control patties were comparable with slight increases in hardness and gumminess of the low-fat product. The developed low-fat ground pork patties (7% milk co-precipitate) had lower TBA values, better microbiological and sensory refrigerated storage stability than high-fat control patties packaged in air permeable films for 21 days.

  • This study aimed to enhance the applications of dates as a food material that can be utilized and stored easily by improving the inefficient process of the traditional cooking procedure. To this end, this study investigated the physico-chemical and nutritional properties of jujube pulp powder, and compared the traditional and newly developed methods of making yakbap, yakpyon, and jujube porridge. According to the analysis of physical and chemical properties, the jujube pulp powder contained 5.4% moisture, 2.6% crude ash, 6.6% crude protein, 0.35% crude fat, and 4.7% crude fiber. The water activity was 0.95% in jujube pulp while it was 0.24% in jujube pulp powder. In addition, the jujube pulp powder had a total sugar content of 70.4% and reducing sugar content of 6.3%. The vitamin C was content was estimated to be 68.5 mg/100 g in the jujube pulp powder and the jujube pulp contained 6.2 g/100 g of dietary fiber. Major minerals were K, Mg, and Ca. After appointing jujube pulp powder (new method) to a test group and jujube pulp (traditional method) to a control group, the sensory evaluation and acceptance testing were conducted for yakbap, yakpyon, and jujube porridge. As a result, there was no significant difference in any sensory factors tested (p<0.05). It was found that making and storing jujube pulp powder by drying jujube pulp is a useful way of utilizing jujube because Yakbab, Yakpyun and jujube porridge were found to have a relatively good appearance, color, flavor, taste, texture and overall acceptance.
