The variation of free amino acids during the tomato producing was studied using a tomato variety, Kagome 77. The concentration of free amino acids in fresh and heated pulp, and in puree and paste was analyzed by using automatic amino acid analyzer, Hitachi model KLA-5. 1. A significant difference in decomposition rate of glutamine and asparagine among amide group was recognized. For instance, the glutamine decomposed fast and no glutamine was found in the paste, while 56% of asparagine was found in the paste. 2. The diminishing quantity of glutamic acid among acid group was highest among all free amino acids. The quantity of aspartic acid was next to the glutamine. The percents of glutamic acid and aspartic acid left over were 38% and 24%, respectively. 3. Glycine, alanine, valine, isoleucine and leucine of neutral amino acids tended to be reduced a little during the heating, concentrating process. 4. No apparent variation was found for the lysine and histidine belonging to basic amino acids. while arginine increased a little. 5. Tyrosine, phenylalanine and tryptophane of aromatic group seemed to increase a little during the heating process. But the variations of them during the concentrating process were not recognized. 6. The methionine content, sulfur containing amino acid decreased a little throughout the process. But the decrease of ${\gamma}-amino$ butyric acid of non-protein was not apparently recognized. 7. The amino acid contents of fresh pulp were found as following order: glutamic acid>${\gamma}$-amino butyric acid>glutamine>aspartic acid>asparagine. The amino acid contents of paste were as glutamic acid>${\gamma}$-amino butyric acid>aspartic acid and aspargine. The percent distribution of aromatic and basic amino acids increased, even it was not great. 8. When amino acids were analyzed by Hitachi KLA-5, unknown peak which was never app eared in the fresh pulp before tryptophane was appeared when processed. The peak became greater when heated and concentrated. Later it was known that the peak was not due to lysinoalanine or ornithine.

Gochujang, a kind of fermented red pepper paste with soybean koji, is a traditionally using spices in Korea and is characterized by its special taste in combination with hot, sweet and salty taste, and its component are consist of protein, carbohydrates, capsanthin and capsinoids, vitamin and other minor components. We tried to develop Gochujang sauce characterized by mild hot and spicy taste, proper viscosity and its strong application to steak, fried food, pizza and others. Gochujang sauce tended to show strong red color and lightness as pH decreases and Paprica oleoresin improved a value to 12.11 and L value to 24.24 which is similar to tomato paste 1:1-1.5:1 ratio of Gochujang and tomato paste was evaluated to be acceptable in the aspect of Gochujang's characteristics.

This study investigated the field application and the acceptance test of the meal service for the elderly (${\ge}$ 65 years) community halls in Jeonnam and Gyeongbuk. The acceptance scores of bean rice and glutinous rice were the highest among the tested cooked rice varieties in Jeonnam and in Gyeongbuk, respectively (P<0.05). The acceptance scores of tofu soybean paste soup and spinach bean paste soup were the highest among different soups, in Jeonnam and Gyeongbuk, respectively. The scores of menu 5 (bean rice, tofu and bean paste soup, pan-fried pork, green laver salad, kimchi, soy milk) and menu 1 (cereal rice, fermented soy bean soup, hard-boiled quail's egg, crown daisy salad, kimchi, mandarin) were the highest in Jeonnam and Gyeongbuk, respectively, in terms of overall acceptance (P<0.05). The average cost of each meal in two provinces was $2012{\pm}323$ won. The amount of leftovers from menu 5 (Bean rice, Tofu and soybean paste soup, Pan-fried pork, Seasoned green laver, Kimchi, Soy milk) was the lowest in Jeonnamin, while the one from menu 2 (rice, leaf beet and soybean paste soup, sated vegetables with potato noodle, hard-boiled potato, kimchi, cherry tomato) was the lowest in Gyeongbuk.
Flavor profiles on regular and low-calorie French type salad dressings were carried out in the two different temperatures(5$^{\circ}C$ and 25$^{\circ}C$). Data collected through consensus discussion. Panelists found less oil flavor and after-taste in the low-calorie dressing, which was to be expected, since water has been substituted for oil to reduce the calories. The two salad dressing had a moderate aroma and flavor of cider venegar, with a slight taste of distilled vinegar. It was balanced by a tomato flavor consisting of tomato paste, tomato sauce, and tomato juice. There were slight aroma and flavor of spices, including onion and galic, and a moderateamount of oil in the regular dressing. The overall sweet and sour flavor impression were in the low-moderate range, and were well balanced. The amplitude of the low calorie dressing was moderate, being slightly higher than that of the regular dressing. Temperature effects seemed to influence more one the low-calorie samples than regular samples.
BACKGROUND: This study aimed to estimate the measurement uncertainty associated with determination of cadmium and lead from tomato paste by ICP/MS. The sources of measurement uncertainty (i.e. sample weight, final volume, standard weight, purity, molecular weight, working standard solution, calibration curve, recovery and repeatability) in associated with the analysis of cadmium and lead were evaluated. METHODS AND RESULTS: The guide to the expression of uncertainty was used for the GUM (Guide to the expression of Uncertainty in Measurement) and Draft EURACHEM/CITAC (EURACHEM: A network of organization for analytical chemistry in Europe/Co-Operation on International Traceability in Analytical Chemistry) Guide with mathematical calculation and statistical analysis. The uncertainty components were evaluated by either Type A or Type B methods and the combined standard uncertainty were calculated by statistical analysis using several factors. Expected uncertainty of cadmium and lead was $0.106{\pm}0.015$ mg/kg (k=2.09) and $0.302{\pm}0.029$ mg/kg (k=2.16), on basis of 95% confidence of Certified Reference Material (CRM) which was within certification range of $0.112{\pm}0.007$ mg/kg for cadmium (k=2.03) and $0.316{\pm}0.021$ mg/kg for lead (k=2.01), respectively. CONCLUSION(s): The most influential components in the uncertainty of heavy metals analysis were confirmed as recovery, standard calibration curve and standard solution were identified as the most influential components causing uncertainty of heavy metal analysis. Therefore, more careful consideration is required in these steps to reduce uncertainty of heavy metals analysis in tomato paste.
A processing factor (PF) has been used to define the maximum residue limits of pesticide in a variety of processed fruit products. This study summarizes PF by the stage of fruit processing based on JMPR reports from 2010 to 2014. When we compared PF of 19 pesticides in apple products during the processing of washing, drying, canning, juice, sauce, puree and pomace, PF was higher than 1 only in pomace. In the comparison of 21 pesticides during the process of grape (washing, juice, wine and raisin), PF was higher than 1 in raisin. In the comparison of 19 pesticides during the process of orange (juice, oil and marmalade), PF was higher than 1 in oil. When 27 pesticides were compared during the process of tomato (juice, puree and paste), paste showed the highest PF value except pomace. During the process of plum (washing, drying and puree) with 12 pesticides, PF was higher than 1 in drying. The correlation coefficients between physical characteristics of pesticide (fat-solubility and volatility) and PF were statistically significant in the processes of apple juice, orange juice, tomato puree and paste and strawberry jam.

1. Background of the Study Old Testament time made some food and Sauces. Cosher food is God's Covernant. Ancient Greek cooking and Roman cooking had been Sauces. Much of what we know of Greek gastronomy is found in the writting of Archestrate, cooking is sigle and direct, Sauces are Cumin, Vinegar, Roman culinary comes from mareus, first century A.D. many of the ingredients used in apicius's recipes are seen againg in midival Eurpean cooking. ① Cumin Sauce for Oyster ② Sauce for grounds, puree, and cardoons. 2. Culinary in the Middle ages Liaquid Flavorings their Sauces tested Verjuice and Vinegar are most often called for when a Liquid is needed, Spices and Liaisons. 3. Cookery the eighteenth century The eighteen the century brought about greated Systemization of basics, coulis, Jus, and bouillons. 4. The twentieth century culinary Careme were Systematized and recorded by Auguste Escoffier in his Guide Culinare Standardized. 5. Grand Sauces are Considered one of the greatest test of a Chef's Skill, Whether they are classics, Such as Sauce, Supreme, demand the highest technical expertise. The Successful paring of Sauce with a good demonstrates an understanding of the food and an ability to judge. Sauce making allows the cook more freedom to work flavors, textures, Aromatics, Tasty, and color than any other area of cooking. A Sauce is never eaten alone, function, balance, the direct flavor, Sauces presents the basic Sauce-making techniques that have been used in the past and that are popular today, Sauces are organized around the primeifhes of classic world cooking 6. Grand Sauces are 1) Brown Sauces are 1) Brown Sauce ① Demiglace ②Espagnole ③ Fond de veau 2) Bechamel Sauce 3) Velote Sauce 4) Tomato Sauce and 5) Hollandaise Sauce ① Brown Sauce made with Stock, Roux, Tomato Paste and Mirepoix. ② Bechamel Sauce made with Roux and Milk. ③ Veloute Sauce made with Roux and White Stock. ④ Tomato Sauce made with Tomto, Vegetable and Stock. ⑤ Hollandaise Sauce made with Egg and Butter.
This study was conducted to evaluate the quality characteristics of low-fat emulsion type sausages containing 0% tomato powder (C), 5.0% ground raw tomato paste (T1) and 0.5% freeze dried tomato powder (T2) during storage at $5{\pm}1^{\circ}C$ for 30 days. The crude protein content of T2 was significantly lower (p<0.05) than that of the other sausage types. Moisture, crude fat and crude ash contents of the sausages during storage were not affected by the addition of tomato. The pH and shear force ($kg/cm^2$) values of C were significantly higher (p<0.05) than those of T1 and T2. There was no significant difference among the different sausages in cooking loss, ranging from $13.00{\sim}14.98%$. The WHC values of T1 and T2 were significantly higher (p<0.05) than that of C. The values of TBARS were significantly (p<0.05) increased for ail sausages following storage. The TBARS value (mg MA/kg) of C was significantly higher (p<0.05) than those of T1 and T2 at 15 days of storage, however T1 was significantly higher (p<0.05) than the other sausages after 30 days of storage. The meat color values tended to decrease with increased storage time. Microorganism analysis revealed that all sausage types did not reach $4.4log_{10}CFU/g$ until 30 days of storage. The texture, brittleness, Hardness, and springiness of each sausage type were not significantly different after 1 day of storage, while the cohesiveness, gumminess and chewiness of T1 and T2 were significantly higher (p<0.05) than that of C. T1 and T2 sausages had a slightly higher score regarding color, aroma, tenderness and overall acceptability, however the sensory evaluation score among the different sausage types was not significantly different (p>0.05). In conclusion, low-fat sausage with added tomato showed higher lipid oxidative stability during storage than sausage to which no tomato was added.
War against Japanese(1592-1599) and war against Manchurian(1636-1637), which had been occurred in Korean Peninsula throughout the history, and frequent trade with foreign countries since $18^{th}$ century have led to a distribution of foreign food into Korea. Several examples for this include tomato, apple, watermelon, maize, pea, cowpea, peanut, potato from China and red pepper, pumpkin, and sweet potato from Japan. Since these foods had been brought into Korea, they have been cultivated suitable for Korea's climate and land. Foreign foods with a few exceptions tend to have high calories. For instance, along with potato and sweet potato, pumpkin is considered a high-calorie food containing lots of starches as it becomes ripening. This helped a wide spread of the foreign foods across the nation where intake of high-calorie foods was critical for Korean people's nutrition at that time. Among those foods introduced from foreign countries, red pepper had a greatest impact on the dietary life-style of Chosun Dynasty. The use of red pepper has been greatly expanded from main ingredient to seasoning and garnishing in various forms of red pepper such as red pepper paste, red pepper powder, and thick soy paste mixed with red pepper. Red pepper was made eating habits is hot besides dye red colored to traditional food, because steaming and boiling is frequently cook method, fermentation food also food color is achromatic therefore food color is and mixture with red pepper, picked fish and chinese cabbage new kimchi culture came into being.

This study optimized the mixing ratios of seafood sauce with blue crab for maximal sensory attributes using a response surface methodology with central composite design. It evaluated sensory appeal, nutritional value, and some rheological properties. The optimal formulation appeared to be 252 g of tomato paste, 78 g of chopped garlic, and 519 g of blue crab block; this ratio resulted in a predicted sensory score of 5.7 (on a 7-point scale) for overall acceptability. Addition of blue crab block increased moisture, ash, and protein contents in various sauces, but fat contents were similar in every sauce. Major free amino acids such as glutamic acid, phospho serine, asparagine, and arginine composed about $60\%$ of the total amino acid content. Standard and optimized sauces were red and light yellow, and those color values were significantly higher than in American-style sauces. Optimal viscosity was half the value of American-style sauces; more blue crab block added to the sauce resulted in lower viscosity. Adding this sauce to seafood dishes will likely aid development of flavoring substances.
