A Study on the Sensory Optimization of Home made Pasta with the addition of Chives
Korean journal of food and cookery science , volume 20, issue 3, 2004, Pages 227~234
To determine the optimum mixing conditions of home made pasta with chives, samples were prepared with various compounding ratios of Durum wheat semolina (99, 198 and 297g), chive paste (27, 45 and 63g) and egg (72, 81 and 90g) using a central composite design, and sensory evaluations were performed and considered using a response surface methodology. The optimum mixing rates of Durum wheat semolina, chive paste and egg were 191.10, 45.53 and 80.98g for color, 149.00, 47.00 and 73.24g for flavor, 185.06, 43.99 and 81.18g for elasticity, and 188.69, 42.32 and 82.36g for overall quality. These results show that Chive paste effect the color and flavor, and Durum wheat semolina and egg effect the elasticity and overall quality.
Standardization of Recipes for Large Quantity Production of Korean Foods (I) -With the Focus on Soups-
Korean journal of food and cookery science , volume 20, issue 3, 2004, Pages 235~246
The objective of this study was to standardize recipes for large quantity production for Korean foods such as Yukkaejang (spicy beef and vegetable soup), Sagol-woogeojitang (bone soup with young cabbage), Kalbitang (beef short-ribs soup) and Seolleongtang (beef and bone soup). We examined the ingredients and the amounts in recipes that were used by 3 groups such as foodservice management companies, commercial restaurants and cookbooks. We analyzed cooking methods from 5 foodservice management companies, 3 commercial restaurants and 2 kinds of cookbooks. Each soup that was made by a standardized recipe was evaluated by consumer sensory panels. The total yield volume and portions for 100 persons were determined as well as ingredients, weights and methods. The standardized recipes were as followed; yield volume after cooking was 38-40kg, optimum service temperature was 78-82
, preparation time was 4-16 hours for 100 persons, and one portion was 380-400g, and we recorded the weight of foods and methods, as well as reference and garnishes. We expect that the standardized recipes for large quantity production will be necessary for use by cooks as well as by food preparation in foodservice institutions.
Identification of foodservice operation evaluation model′s criteria items for certifying contract foodservice management company
Korean journal of food and cookery science , volume 20, issue 3, 2004, Pages 247~255
The foodservice industry is changing more and more from on-site foodservice management to contract foodservice management. However there are differences according to the level of management and operation of contract foodservice management company (CFMC). The necessity of certification on CFMC is increasing to enable fair discrimination of CFMC among most clients that want to contract with CFMC. This study was performed to identify the foodservice operation evaluation model's criteria items for certifying CFMC. The analysis research methods included literature review, content analysis, individual interview, Delphi technique, and brain storming. First, the following infrastructure items were prepared in the contractor's viewpoint: procurement, transparency of operation, menu development and operation system, nutrition service system, professional employee education, sanitation andsafety management system, customer satisfaction system, facility system, management information system (MIS), business and economics. Second, the evaluation criteria required by the contractor on the client's view point was similar to school foodservice, hospitalfoodservice, and business andindustry foodservice except extraordinary items of field. Third, evaluation criteria and detail categories and items were identified such as financial focus, customer focus, process focus, human focus, and renewal and development by grafting on intellectual capital evaluation methodology for CFMC.
Effects of gamma irradiation on the functional and structural characteristics of soy protein isolates
Korean journal of food and cookery science , volume 20, issue 3, 2004, Pages 256~264
The effects of irradiation on the functional and structural characteristics of soy protein isolates were studied. Soymilk was irradiated at 1, 5, and l0kGy, after which soy protein isolates were prepared. The functional properties of soy protein isolates were examined including solubility, emulsion capacity and stability, foam capacity and stability, structural properties as represented by SDS-PAGE pattern, and secondary and tertiary structures. The solubility and emulsion capacity were increased by radiation treatment at 1kGy however the values were adversely affected again as dosage was increased above 5kGy. As irradiation dosage increased, an increase of foaming capacity at 1kGy and a decreasing turnover afterwards were also noted in foaming capacity, although the differences were not statistically significant. The SDS-PAGE pattern showed fragmentation and aggregation of protein molecules as affected by irradiation in proportion to the dosage increase. The results of CD and fluorescence spectroscopy revealed increased aperiodic structure contents with the dosage increase. It was assumed that irradiation dosagefrom 5 to l0kGy could initiate minimal denaturation of protein in various foods compared to general heat treatment.
Comparison of Pyrazines Formed in Chicken By-Products Hydrolyzed by Enzymes
Korean journal of food and cookery science , volume 20, issue 3, 2004, Pages 265~270
To investigate the formation of pyrazines, by-products of chicken were hydrolyzed by protease/peptidase for 4, 8 and 24 hours, after which the hydrolysates were heated with glucose, fructose and xylose, respectively, at l80
for l00min. The formation of pyrazines showed a significant difference by quality and quantity according to the degree of protein hydrolysis. Especially, the formation of 2-methyl pyrazine and 2-ethyl-5-methyl pyrazine was considerably affected by, the degree of protein hydrolysis. Also, 3-ethyl-5-methyl pyrazine, 2-butyl-3-methyl pyrazine, 2-butyl-3,5-dimethyl pyrazine, methyl pyrazine, and 3-ethyl-5-methyl pyrazine were identified only in the hydrolysates for 24 hours.
Preparation of mixed beverages for breakfast made primarily with the hydrolysate of sweet potato and its quality characteristics
Korean journal of food and cookery science , volume 20, issue 3, 2004, Pages 271~278
As an attempt to develop new functional beverages for breakfast, sweet potato based beverages were prepared with hydrolyzed sweet potato, potato, and carrot products (sample : water = 1 : 1), and their chemical and sensory properties were evaluated. The content of reducing sugar and soluble solid of the sweet potato, potato, and carrot increased with enzyme treatment, while their viscosity decreased without significant change of color. The hunter color test showed that the beverages with 10％ carrot content were high in redness leading to a decrease in their acceptability for sensory evaluation. The sensory score of the mixture containing 5％ carrot was good, but beverage with 0％ carrot reduced the sensory properties. The results showed that the final ratio of sweet potato to potato to carrot for the new functional beverage was 5 : 4.5 : 0.5. The pH of the beverage was adjusted to 5.0, 4.5, and 4.0 using an organic acid mixture. In the sensory test of the new functional beverage, the best sensory score(color, taste, smell, and texture) was the mixture of sweet potato : potato : carrot equaling 5 : 4.5 : 0.5 with a pH of 4.5.
Quality Characteristics of Pumpkin Jam when Sucrose was Replaced with Oligosaccharides during Storage
Korean journal of food and cookery science , volume 20, issue 3, 2004, Pages 279~286
The physicochemical and sensory qualities of pumpkin jams, in which sucrose was replaced with oligosaccharides, were investigated during storage at 20
. pumpkin jam was prepared with steamed grind pumpkin, mixed with either sucrose only(50％), corn syrup(COS, sucrose 30％＋COS 20％), fructooligosaccharide (FTO, sucrose 30％＋FTO 20％), isomaltooligo saccharide (IMO, sucrose 30％＋IMO 20％), or galactooligo-saccharide(GTO, sucrose 30％＋GTO 20％). The final sweetness of each pumpkin jam was 64
Brix. During 60days of storage there were no differences in acidity and pH among the treatments. Reducing sugar content was higher in the pumpkin jam containing COS compared to 次e others. During storage Lightness(Hunter L), redness(a value) and yellowness(b value) increased, of which L and b values were the highest in COS, and the a value were higher in sucrose compared to the other sugars. Adhesiveness and hardness of textural properties were the highest in sucrose. Sensory evaluation results showed that the mean scores of over-all acceptability during storage did not significantly decrease until the 30th day of storage, compared to the freshly made jams. Physicochemical and sensory characteristics of pumpkin jams during storage in a PCA plot were comprised of the first principal component (99.44％) and the second principal component (0.54％).
The Growth Inhibition against Gastric Cancer Cell in Germanium or Soybean Sprouts Cultured with Germanium
Korean journal of food and cookery science , volume 20, issue 3, 2004, Pages 287~291
The growth inhibitory effect of germanium, or soybean sprouts cultured with germanium, on cancer cells was determined in the cultured gastric cancer cell line, AGS. The growth of AGS was significantly inhibited by the addition of 0.01-1％ organic germanium (Ge-132) and germanium stone powder in MTT cytotoxicity assays. The juice from germanium treated soybean sprouts (GTS) inhibited the growth of AGS gastric cancer cells by 78-88％ at concentrations of 2.5 or 5
. The juice from Seomoktae GTS revealed an especially higher growth inhibitory effect than that from the control soybean sprouts (germanium non-treated soybean sprouts, GNTS) in AGS. The results suggest that soybean sprouts cultured with germanium may exert an anticancer effect against gastric cancer cells.
