The study was conducted to evaluate the feasibility of Mozzarella cheese analogue generation by using a mixture of soy milk and raw milk and to compare the quality of the resultant cheese with that of Mozzarella cheese manufactured using the traditional method. The mixtures showed increase in protein and decrease in lactose and SNF in a dose-dependent manner with the addition of soy milk. The Mozzarella cheese analogue had lower total solids content than the control cheese product, while the fat content was similar between both. The analogue cheese had lower ash content than the traditionally prepared cheese; the content was proportional to the amount of soy milk in the mixture. Higher soy milk quantities within mixtures also resulted in proportionally higher levels of fat content within analogue cheese. Water-soluble nitrogen content was lower in the analogue cheese than in the control cheese. While the WSN level increased in the control cheese, it was almost constant in the analogue cheese. The control cheese had much higher actual and predicted yield than the analogue cheese, while the analogue cheese had a higher stability level. The control cheese had a higher transfer rate than the analogue cheese, with the exception of lactose. Electrophoresis analysis showed bands for Mozzarella cheese analogues that were present in addition to the normal ${\alpha}$-casein and ${\beta}$-casein bands. Physical characteristic analysis showed that hardness was affected by the addition of soy milk to cheese, while cohesiveness and brittleness were affected by the addition of raw milk, and elasticity was barely affected by milk composition. The meltability of the control cheese was higher than that of the analogue cheese and increased during 30 days of storage at $4^{\circ}C$. Browning, oiling-off, and stretching characteristics were almost identical between the 2 types of cheeses. Sensory evaluation findings showed that the control cheese had much better body texture, appearance, and flavor than the analogue cheese.
The purpose of this study was to develop Mozzarella cheese analogues by using dairy products in the form of WPC 34, WPC 80, whey protein, demineralized whey powder, and lactose powder along with soy milk. Soy milk was separately blended with 5% WPC 34 (A), WPC 80 (B), DWP (C), WP (D), and LP (E) and also with 10% WPC 34 (F), WPC 80 (G), DWP (H), WP (I), and LP (J). Blending of soy milk and whey products showed that increase in the proportions of whey products (WPC 34, WPC 80, DWP, WP, and LP) led to increase in the protein, lactose, and SNF levels of the admixture. A decrease in fat content was observed for all cheeses prepared from mixtures, relative to those for the control cheese. The nitrogen content within analogue samples was higher than that in the control cheese and increased with increase in the proportions of whey products within soy milk. Higher water soluble nitrogen levels were observed in cheese prepared from whey-product-blended soy milk than in the control cheese. The non-protein nitrogen level within the control Mozzarella cheese was significantly lower than that in the Mozzarella analogues, and, in the case of cheese analogues, it increased with increase in the proportion of whey products in soy milk. With regard to the physicochemical and sensory qualities of the Mozzarella cheese analogues and control cheese, the pH of all analogue samples, with the exception of the cheese prepared from group G, was lower than that of the control Mozzarella cheese. Rheological studies showed that the hardness of Mozzarella cheese analogues was lower than that of the control Mozzarella, while the elasticity, cohesiveness, and brittleness of the analogues was higher. The control sample had a higher meltability level than any of the Mozzarella analogues. Mozzarella cheese prepared with the traditional method had higher browning and stretching levels than all the cheese analogues, but a lower oiling-off level.

The purpose of this study was to investigate the effects of adding various amounts of ingredients on the physicochemical and sensory characteristics of Bokbunja-jelly. The proximate composition of Bokbunja-jelly was 19.0% for the moisture and 0.8% for the crude protein. The Hunter L-values of Bokbunja-jelly prepared by adding 10 g RME or 120 g sucrose were higher than that of Bokbunja-jelly prepared by adding 20 g RME or 100 g sucrose. The Hunter b-values of Bokbunja-jelly prepared by adding 20 g RME or 120 g sucrose was higher than that of Bokbunja-jelly prepared by adding 10 g RME or 120 g sucrose. The hardness and chewiness were increased with decreasing Rubus coreanus Miquel extracts. According to the results of the sensory evaluation, no significant differences in flavor, sweetness, hardness, elasticity and overall qualities were found. According to the results of physicochemical properties and sensory evaluation, the optimal recipe for preparation of Bokbunja-jelly was determined to be 240 g water, 120 g sugar, 110 g glucose syrup, 4 g agar, 20 g Rubus coreanus Miquel extracts and 0.3 g Rubus coreanus Miquel flavor.
This study investigates the quality characteristics of mung bean starch Jelly by addition of different ratios of white lotus(Nelumbo nucifera) root powder during 5 days of storage at $4^{\circ}C$. The moisture content of the samples ranged from 86.78 to 88.88%. The L value of the samples decreased as the amount of white lotus root powder increased; however, the a value and b value were significantly(p<0.05) increased. For the sensory evaluation, color and taste were decreased as the amount of white lotus root powder increased. Flavor and shine were not significantly different among the samples. And clarity and elasticity were highest in the sample with no powder and 5% of white lotus root powder. Hardness was decreased(p<0.05) as the amount of white lotus root powder increased. Overall acceptability was highest when using 0% and 5%. Texture profiles of hardness decreased as the amount of white lotus root powder increased. Hardness, gumminess, chewiness were found to drop significantly(p<0.05) after one day of storage. Cohesiveness was not significantly different among the samples according to the amounts of white lotus root powder. Adhesiveness was not significantly different in 0, 5, 10, and 15% of white lotus root powder. Syneresis was increased during the storage period. From the result, the most advisable mixture ratio of mung bean starch jelly with white lotus root powder was 19 g of mung bean starch, 1g of white lotus root, 0.1 g of salt and 160 mL of water.
A study was conducted to investigate the effect of ACAMS(Autoclaved-cooled amylomaize VII) and ACNMS(Autoclaved-cooled normal maize starch) containing resistant starch(RS) on ASW (Australian wheat flour) rheology and noodle quality. The water absorption in farinograph increased with the addition of ACAMS and ACNMS, but the dough stability decreased with the addition. The ACNMS added flours showed the highest initial pasting temperature and the lowest peak viscosity in RVA. The addition of ACAMS and ACNMS were not effective on the weight and volume of cooked noodles during cooking time for 5 min. However, as the cooking time increased, noodle weight and volume were the highest in control(no RS added flour) and the lowest in ACNMS added flours. Noodle texture was evaluated using rheometer. The hardness of RS(ACAMS, ACNMS) added noodles was higher than that of control. Cohesiveness was significantly different between control and ACAMS added noodles, but the cohesiveness of ACNMS added noodles was similar to other noodles. The elasticity of ACNMS added noodles in sensory test was lower than that of control but the smoothness and overall acceptibility were higher.

The texturization characteristics of textured vegetable protein (TVP) were investigated based on the extent of soybean decoating during the pretreatment of defatted soybean flour used for TVP. The raw materials for TVP consisted of 50% defatted soybean flour, 30% gluten, and 20% corn starch. The weight ratios of soybean seed coat to soybean flour were 9%, 6%, 3%, and zero. Extrusion was performed using an extruder equipped with a cooling die, maintaining a barrel temperature of 190℃ and screw speed of 250 rpm, Water was injected at a rate of 9 rpm using a metering pump. Regarding the textures of the extruded TVPs produced from defatted soybean flour, an increase in the soybean seed coat content led to a decrease in the apparent fibrous structural layer and an increase in hardness. However, there were no significant changes in elasticity and cohesion. Moreover, as the soybean seed coat content increased, the pH of TVPs decreased. A higher soybean seed coat content also tended to lower the moisture content, increasing water absorption, solids elution, and turbidity. These results suggest that an increased seed coat content reduces the proportion of protein, and the fibers present in the seed coats prevent texturization.

In order to process instant foods which hold appropriate moisture contents and soft texture, four kinds of retort pouched seasoned-oyster products were prepared as control, seasoned products, solid smoked and liquid smoked product after seasoning and their processing conditions and quality stability during 100 days of storage were investigated. The optimum processing conditions of retort pouched seasoned-oyster product were as follows ; namely, raw oyster was seasoned at $105^{\circ}C$ for 10 min with seasoning solution prepared from sugar, sorbitol, salt, monosodium glutamate and 5'-ribonucleotide and then dipped for 30 seconds in Smoke-EZ solution(Alpha Foods Co., Ltd.) after predried for 30 min in hot-air drier. After. smoking, the seasoned and liquid smoked oyster was dried at $40-42^{\circ}C$ for 2.5 hours, vacuum packed in plastic film bag, and sterilized in a hot water circulating retort at $120^{\circ}C$ for 16 min. Comparing their quality before and after sterilization, TBA value of all the products after sterilization slightly decreased and among texture profiles hardness, toughness and chewiness slightly decreased, while elasticity and cohesiveness were rarely changed. Color value (a value) of the product treated with solid smoke or liquid smoke increased after sterilization. During storage pH, VBM and water activity of all products changed little and TBA values of the solid smoked product and liquid smoked one were lower than that of the others. Viable cell count was negative and texture changed little during storage. As for color difference during storage, green meat appeared on the surface of control and seasoned product after 15 days storage, while the masking of green meat could achieved by solid and liquid smoking treatment. And liquid smelling treatment was more effective than solid smoking. As a conclusion, retort pouched seasoned-oyster product treated with liquid smoke kept their good quality during 100 days storage and it seemed to be consumed as one of the instant foods which hold appropriate moisture contents and soft texture.

As one of trials to process instant sardine foods which can be preserved at room temperature, three kinds of products were prepared as seasoned-dried product (control, C), liquid smoked seasoned-dried product(S) and antioxidant treated seasoned-dried product(E), and their processing conditions and quality stability during storage were examined. Raw sardines were dressed, steamed and then filleted. The sardine fillets were seasoned with the mixed seasoning solution containing $28.0\%$ of sorbitol, $14.0%$ of sugar, $5.6\%$ of table salt, $1.8\%$ of monosodium glutamate, $0.6\%$ of garlic powder and $50.0\%$ of water at $5^{\circ}C$ for 15 hours, and dipped for 45 seconds in $10\%$ Smoke-EZ solution. After liquid smoking, the seasoned and liquid smoked sardine fillets were dried at $45^{\circ}C$ for 4 hours, vacuum packed in laminated plastic film bag(polyester/casted polypropylene= $12{\mu}m/70{\mu}m,\;15{\times}16cm$), and finally pasteurized in water at $95^{\circ}C$ for 30 minutes. The results obtained from chemical and microbial experiments during storage are as follows : the moisture contents, water activity and pH of the products showed little change, and VBN of them slightly increased during storage. The TBA value and POV of the products (E, S) were lower than those of control product(C) considerably. In color values, L value (linghtness) decreased while a and b value (red and yellow) revealed a tendency to increase during storage. The fatty acid composition of the products were similar to those of raw sardine, the predominant fatty acids were 16:0, 20:5, 18:1 and 22:6. The products (E, S) have a good preservative effect on highly unsturated fatty acids during storage. Viable cell counts of those products were negative and histamine contents were less than 2.0 mg/100 g. Among the texture profiles, hardness, elasticity and cohesiveness of the products slightly decreased during storage. Judging from the sensory evaluations, liquid smoked seasoned-dried product(S) was the most desirable, and the products could be preserved in good condition for 40 days at $25{\pm}3^{\circ}C$.
Hardness and elasticity for SurichwijuIPyun(Korean rice cake supplemented with Surichwi) made with various levels of Surichwi(O∼40%) boiled in 1% sodium bicarbonate added water were decreased by increasing additional rate of Surichwi, but adhesiveness and cohesiveness didn't show constant increase or decrease. Guminess and chewiness showed significant differences by decreasing additional rate of Surichwi. As a results of sensory evaluation of Surichwiiulpyun, Julpyun supplemented with 20fs Surichwi showed the most favorite tendency in color, flavor and overall acceptability. Textural characteristics of Surichwijulpyun supplemented with 20 and 30% Surichwi in storing at 20$^{\circ}C$ showed less change than those of 0 and loft group. Gumminess and chewiness showed similar trend to hardness, and there were significant differences in additional rate of Surichwi and storage time.
