This study was designed to investigate the preparation of canned pufferfish and its quality during storage at 4$^{\circ}C$${\pm}$0.5 and 25$^{\circ}C$${\pm}$0.5. The proximate compositions of the raw pufferfish were moisture 77.8%, protein 18.4% and lipid 3.3%. After the preparation of canned pufferfish there were no significant changes. During storage at 4$^{\circ}C$${\pm}$0.5 and 25${\pm}$0.5, the amino nitrogen(NH2-N) contents and acid value(AV) in both the raw and canned pufferfish revealed little difference. The volatile basic nitrogen(VBN) contents in the raw and canned pufferfish were in the range of 10.7mg/100g∼19.2mg/100g, and had no change during storage. Viable cell counts of the canned pufferfish had no change during storage at 4$^{\circ}C$${\pm}$0.5 and 25$^{\circ}C$${\pm}$0.5. The toxicity was below 2MU/g in the raw pufferfish, and it was also nontoxic in the canned pufferfish during storage.

Clostridium botulinum spores are widely distributed in nature. Type A and proteolytic type B bacteria produce heat-resistant spores that are primarily involved in most of the food-borne botulism outbreaks associated with low-acid canned foods. Food-borne botulism results from the consumption of food in which C. botulinum has grown and produced neurotoxin. Growth and toxin production of type A and proteolytic type B in canned foods can be prevented by the use of thermal sterilization alone or in combination with salt and nitrite. The hazardousness of C. botulinum in low-acid canned foods can also be reduced by preventing post-process contamination and introducing hazard analysis and critical control point (HACCP) practices during production. Effectiveness of non-thermal technologies such as high pressure processing with elevated process temperatures on inactivation of spores of C. botulinum will be discussed.

As a part of basic investigation for utilization of canned food processing by-products, a food components of the canned oyster processing waste water such as boiled and released water(BRW), wash water(WW) were investigated and compared with hot-water extracts from oyster. From the results of measuring heavy metal conte수, viable cells and coliform group, the canned oyster processing waste waters might not invoke health risk in using food resource. The contents of taste compounds (free amino acids, ATP related compounds, TMA (O) and total creatinine) of BRW and WW accounted for about 254% and 95%, respectively, in comparison with those of control (hot-water extract from oyster). The BRW showed a very high content of salt in comparing to the WW and control. In descending order, the values of whiteness index was WW, control and BRW. Sensory scores for color, oyster flavor intensity and saline taste were not significantly different between WW and control. But, BRW had the highest score in oyster flavor intensity, while had the lowest score in color and saline taste. But, the color and saline taste of BRW might be able to control by some pretreatment (concentration and drying in mild condition, desalination and recipe control etc). These results indicated that BRW and WW generated from various step during canned oyster processing could be a potential food resource by controlling of saline taste and color intensity.

Analytic data on the content of Pb and Sn from twenty five samples of fruit canned In the open market is as follows. The content of Pb and Sn from twenty five samples of fruit canned In the open market was less than Korean laws of food hygiene. The content of Pb and Sn increased In the long time of self life. In comparison with fruit flesh and nectar, nectar showed a tendency to less content.

The influence of spice (cinnamon, allspice, black pepper)-oil extract on canned seafood quality was studied. During the processing of canned seafood, the substitution of spice-oil extract for vegetable oil (refined sunflower, corn, soybean and olive oil) resulted in a decrease in the heat resistance of spore microorganisms, making it possible to reduce the duration of sterilization for canned food to 5-10 min at $115^{\circ}C$. This reduction in the sterilization duration of canned seafood with spice-oil extract inhibited residual microflora in the product, thus reducing the deleterious effect of heating on the main food compounds while preserving protein digestibility.

팽창된 깐포도 및 복숭아 통조림을 시중에서 수거하여 부패현상을 검사한 결과 pH가 비교적 낮은 깐포도 통조림은 52개의 팽창관중 6개가 또 pH가 비교적 높은 복숭아 통조림은 23개 중 19개가 미생물에 의해 부패되었음을 알았다. 깐포도 통조림의 주요 부패 미생물은 Saccharomyces cerevisiae였고, 복숭아 통조림의 주요 부패 미생물은 S. cerevisiae 및 Torulopsis stellata로 밝혀졌다. 기타 Lactobacillus 및 Leuconostoc속의 젖산균도 흔히 발견되었으며, 포자형성세균으로는 Bacillus licheniformis가 한 개의 통조림에서 발견되었다.

In this study, a nanoemulsion formulation for encapsulating turmeric extract was developed and its physicochemical characteristics including particle diameter, zeta potential, polydispersity index, and stability were determined. The turmeric nanoemulsion (TE-NE) droplets exhibited small diameter (165 nm), low PDI (0.17), and high zeta potential (-31.80 mV), all desirable characteristics in nanoemulsions, as well as stability in a wide range of pH. The TE-NE was spray-dried as a means to allow its incorporation into food products and reduce potential transport and storage costs. The resulting powder exhibited a pale yellowish appearance and had a curcuminoids content of 0.39 mg/g. The spray-dried TE-NE powder was incorporated into minced pork to make canned ham, and the sensory characteristics of the ham were evaluated. As a result, the canned ham incorporating TE-NE powder received the same overall acceptability score as the control, and only exhibited slight yellowing. By contrast, ham incorporating turmeric extract exhibited substantial yellowing, and its appearance was considered less acceptable by the panelists. Therefore, the TE-NE formulation could be incorporated into canned ham and other meat products without substantially affecting their sensory qualities.

Four-dimensional response surface methodology was applied to determine the optimum preparation conditions and to monitor sensory qualities of canned oyster mushroom during preparation. The optimum preparation conditions predicted for each corresponding sensory parameter of canned oyster mushroom were 181.29 g of oyster mushroom 205.36 ml of solution and 6.49min of roasting time for color, 214.01g, 195.79ml and 5.07min for appearance, 227.71g, 224.26ml and 6.50min for flavor, 250.30g, 183.63ml and 17.32min for taste, 211.59g, 178.21ml and 17.79min for mouth-feel, 249,.02g, 188.79ml and 17.80min for overall palatability of canned oyster mushroom, respectively. The optimum conditions, which satisfied with all sensory properties of canned oyster mushroom, were 240g, 200ml and 17min for content of oyster mushroom, content of solution and roasting time, respectively. Sensory scored predicted at the optimum conditions were in good agreement with experimental ones.

국내의 음료제조회사 4곳의 캔 커피음료를 구입하여 $65^{\circ}C$ 항온기에 온장하면서 시간의 경과에 따른 커피 중 납 함량의 변화를 관찰하였다. 납은 질산으로 산 분해 후 GFAAS로 분석되었다. 그 결과 보존기간 16주까지도 납 함량의 증가는 관찰되지 않았으며 함량 수준도 기준치인 2.0 mg/kg에 훨씬 못 미치는 불검출 -0.033 mg/kg 수준이었다. 이로부터 온장 캔 커피의 음용시 납에 의한 위해성은 없을 것으로 판단된다.
