The effect of smoking on the quality sausage Sausages were prepared from beef, port, chickens, games, fish and shellfish with polyphosphate salt and spices. Sausage history goes back to 3,000 years of age. The procedure of sausage 1) Meat Curing 2) Meat Control 3) Add Spices 4) Permissible Ingredients 5) Grinding 6) Mixing Emulsion 7) Stuffing 8) Showing 9) Smoking 10) Cooking 11) Drying 12) Packaging Sausage Product to get information on the effect of smoking onto the quality of meat produces. Sausage was smoked under a given conditions. Smoking was conducted as 35f$^{\circ}C$to 6$0^{\circ}C$ the related humidity of smokehouse was still at 60 to 70 percent. Results are as follows: 1. The Penetrated smoke in sausage was prolonged < p.<0.02 when sausage was smoked 2hours at 60~$65^{\circ}C$ the penetrated amount of free acetone in sausage was 0.5mg%. 2. Peroxide value of sausage as heating treatment both at 3$0^{\circ}C$ and at 5$0^{\circ}C$ was prolonged. 3. When sausage was heated at 3$0^{\circ}C$, bacteria of sausage increased In number while at 60~$65^{\circ}C$ bacteria of sausage increased In number fourteen hours. 4. When sausage was treated with smoking the distribution of free amino acids in sausage was changed markedly. 5. The longer smoking time of the products was the higher the content. 6. In case of oak wood smoke flavoring all of test samples. 7. Rapid decrease of does-response mutagenic curve of the smoke flavoring of oak wood and apple wood by in the peak of curve and phenol in the smoke flavoring. Continuous efforts are required to make sausages easily in the butcher shops and in the restaurants. 8. Sausage texture evaluation has 13 rules.

This study was carried out to determine the optimal storage conditions by examining the effects of the storage conditions on the quality of red pepper powder during storage in households. Red pepper powder was stored at room temperature ($20^{\circ}C$), refrigeration (2 and $-1^{\circ}C$) and frozen (-5 and $-20^{\circ}C$) for 3, 6, 9 and 12 months. The ASTA color value, capsanthin content and redness ($a^{\ast}$) of the red pepper powders stored at -5 and $-20^{\circ}C$ were not decreased significantly depending on the storage temperatures until 9 months. The pH of red pepper powder stored at $20^{\circ}C$ decreased significantly until 9 months and increased at 12 months. The microbiological quality of the red pepper powder stored at -5 and $-20^{\circ}C$ was more stable during long-term storage. In the sensory evaluation of red pepper powder stored under all conditions, the overall freshness, redness, hot flavor, moisture release, and edibility decreased with increasing storage period from the control to 12 months. Moisture release increased from 3 months to 12 months. Overall, red pepper should be stored at low temperatures (2, $-1^{\circ}C$) for up to 6 months, and frozen (${\geq} -5^{\circ}C$) for 6 to 9 months. The optimal temperature for long-term storage (${\geq}9$ months) was $-20^{\circ}C$.

This study was aimed to determine the cooking properties of noodles when dfferent concentrations of Aster scaber THUNB(AST) juice were added to the buckwhenat and wheat flours. Also, physicochemical effects of the noodles and compositions of the noodles and compositions of the noodle soup after cooking were determined. Buckwheat flour and AST contained greater amounts of minerals and essential amino acids than wheat flour. The contents of chlorophyll and carotenoids in the buckwheat noodle added AST juice increased as the concentrations of AST juice increased. Hydration capacity of buckwheat flour was higher than that of wheat flour when AST juice was added to flours. The added amounts of AST juice did not affect the volume and the weight of the noodles, but those were increased as cooking time proceeded. The release of proteins and minerals from the buckwheat noodle added AST juice increased as cooking time progressed and also at the added concentrations of AST juice increased. Texture indices showed lower values as the amount of added juice increased. In sensory evaluation, the scores of color, flavor and overall acceptability of the buckwheat noodle added AST juice were higher than those of the control.

This study was carried out to investigate the addition of water-soluble isoflavone into milk by means of microencapsulation technique. The yield of microencapsulation, sensory attributes, and capsule stability of water-soluble isoflavone microcapsules in milk were measured. Coating materials used was polyglycerol monostearate (PGMS), and core material was water-soluble isoflavone. The encapsulation yield of water-soluble isoflavone with PGMS was 67.2% when the ratio of coating material to core material was 15 : 1. The rate of water-soluble isoflavone release from capsules was 18, 19, and 25% when stored at 4,20, and $30^{\circ}C$ for 12 days in milk, respectively. In sensory evaluation, beany flavor and color of microencapsuled water-soluble isoflavone added milk were significantly different from uncapsuled water-soluble isoflavone added milk, however, bitterness was not significantly different. In vitro study, micro-capsules of water-soluble isoflavone in simulated gastric fluid with the range of 3 to 6 pHs were released 3.0∼15.0%, however, the capsules in simulated intestinal fluid with pH 7 were released 95.7% for 40 min incubation time. In conclusion, this study provided that PGMS as coating materials was suitable for the microencapsulation of water-soluble isoflavone, and the capsule containing milk was almost not affected with sensory attribute.

This study was conducted to investigate whether egg-shell may be used as a mineral sourceor leavening agent in breadmaking. In Korea the waste volume of egg shell has been estimated at about 28,694 tons per year. Carbon dioxide generation maxima were established for barking powder$(153{\pm}3ml/g)$, egg-shell(205in reaction with lactic acid) and yeast$(115{\pm}3ml/sugar\;g)$. Gas release time required for each substance to reach $CO_2$ maximum was, for baking powder 7 minutes, for egg-shell 45 mins and for yeast 240 mins. Particle size of egg-shell in breadmaking was suitable more than 20 mesh (-). When egg-shell only was added to the basic formular without including lactic acid, no leavening effect was observed. However, when lactic acid and egg-shell were used together, the leavening effect was more or less equivalent to that of yeast(control). Addition of egg-shell was found to increase calcium content of bread products without noticeable altering flavor, as compared with control. Joint use of egg-shell was organic acids in breadmaking was shown to have potential in time saving, volume increase and yeast saving.

In this study, the following is the result of measuring the quality characteristics of herbal wine and the active inhibition of Glutathione S-transferase in order to measure the release of physiological active substances according to the concentration of extracts. The pH level of herbal wine was 4.4, up from 3.9 before fermentation. These changes are attributed to fermentation and organic acids during alcoholic fermentation. The acidity of herbal wine was 0.55%, about six times higher than the pre-fermentation control of 0.09%. These results show that organic acids are used for flavor formation, ether, in combination with alcohol. The inhibitory activity of glutathione S-transferase were $5.1{\pm}0.31$ in herbal wine 15%, $6.5{\pm}0.6$ in herbal wine 20%, $7.6{\pm}0.6$ in herbal wine 25%, $8.4{\pm}0.2$ in herbal wine 30% and $9.7{\pm}0.7$ in herbal wine 35%. As the extract concentration was increased the inhibitory activity of glutathione S-transferase were significantly increased (<0.05).

Nutritional quality of accelerated salt-fermented anchovy sauce using shrimp processing byproduct as fermenting aids was characterized and compared with commercial anchovy sauce. Four types of sauces were fermented with 0 and $10\%$ addition of shrimp byproducts ($24{\pm}2^{\circ}C$, for 270 days), and 20 and $30\%$ addition of those ($24{\pm}2^{\circ}C$, for 180 days), respectively. Extractive nitrogen content (1,431 to 1,569 mg/100g) of anchovy sauces increased as additional ratios of shrimp byproduct increased. According to the results of ommission test, the taste of all anchovy sauces was influenced by the content of free amino acids, such as mainly glutamic acid and aspartic acid. Regardless of additional ratios of shrimp byproducts, all sauces were similar in total amino acid content ($9,848\~10,324$ mg/100 g), which were 2 times higher compared to that of the commercial sauce. Proline, valine and histidine contents of sauces tend to decrease as the additional ratios of shrimp byproducts increased, whereas methionine, isoleucine, leucine, phenylalanine and lysine contents increased. Increase of some amino acids and mineral content of sauces by increasing of additional ratios was due to release from shrimp byproducts. Sensory evaluation showed that scores of color, flavor and taste of the sauce added with $20\%$ shrimp byproducts_were significantly higher than those of other sauces (p<0.05). In the useful utilization aspects of seafood processing byproducts, shrimp byproducts were good resource for accelerated fermentation and nutritional improvement in preparation of fish sauce.
