This study was carried out to examine the effect on the contents of dietary fiber, mechanical properties, and sensory quality of bread contained with 10% of high-fiber Camellia (Camellia japonica L.) seed flour. Bread added by dietary fiber was the contents of moisture, protein and ash higher than control bread, while the contents of lipid lower than that of control bread. The high-fiber with Camellia seed flour contained 8.6% soluble dietary fiber, 43.7% insoluble dietary fiber, and 52.3% total dietary fiber. The ratio of insoluble dietary fiber/soluble dietary fiber in the high-fiber with Camelia seed flour was 5 times. Bread with the addition of dietary fiber contained 6.9% total dietary fiber. With the addition of dietary fiber, water absorption , mixing time loaf weight, and hardness increased, but the loaf volume decreased . The sensory quality on bread added by dietary fiber was somewhat low in color, appearance, crumb texture, mouthfeel, flavor and overall preference was higher than that of control bread.

Changes in the Qualify Properties of Doenjang Prepared using the Powder or extracts of Paecilomyces japonica were investigated during fermentation at 20$^{\circ}C$. The moisture content was increased during fermentation but was not significantly different in all treatments. The pH of Doenjang with p. japonica was lower than the control group and decreased with the fermentation time. The amino nitrogen content increased gradually for up to 60 days and decreased slightly at 90 days. The L, a and b value decreased in proportion to the fermentation period and those of Doenjang with P. japonica powder were the lowest. From the results of the sensory evaluation, the color of the control group was similar to "yellow" but that of the Doenjang made from powder of P. japonica was close to "dark brown" and those of the Doenjang made from the P. japonica extract were darker than that of the control group. The texture was "glossy and smooth" in all cases and preference about the texture was high. The Doenjang with added P. japonica Powder had a saltier taste and the Doenjang with P. japonica Powder had the least sweet taste. In the flavor and overall Preference, the Doenjang with P. japonica powder was the lowest.

With a view to improving the method of rice marketing quality estimation, vaietal milling characteristics and apparent qualities were studied and their statistical interrelationships were computed for 2 years crops, using 22 varieties of Japonica type and Japonica x Indica type (Tongil). The milling yield was the highest for Japonica, while the broken rice yields was the highest for Japa.xInd. type. But bran yield did not show any significant differences among rice types. Milling factors were volume weight of brown rice, dehulling yield, and Polishing yields; the better these factors, the higher the yield. High apparent quality milled rice with high milling yield were produced from rice types whose broken rice, chalked rice, husk yield and bran yield were little and/or low.

This study was conducted to test the fermenting of high quality vinegar using Wasabi japonica Matsum leaves. Alcohol fermentation with Wasabi japonica Matsum leaves resulted in the reduction of sugar and sugar alcohol content during fermentation, which decreased sharply over 3 days. The alcohol content was maximized (15.4%) after 8-days of alcohol fermentation at $27^{\circ}C$ by adjusting the initial sugar concentration to $27^{\circ}Brix$, and vinegar with an acidity of 5.1% was obtained after 21-days of acetic acid fermentation at $30^{\circ}C$. The pH was shown to be 3.5 after 21-days of acetic acid fermentation at $30^{\circ}C$. Regarding the color of Wasabi japonica Matsum leaves vinegar, the L and b values increased according to fermentation time, whereas a color values decreased. In conclusion, based on the above results, it is determined that the use of Wasabi japonica Matsum leaves allows for the production of high-quality vinegar.

The endeavors enhancing the grain quality of high-yielding japonica rice were steadily continued during 1980s∼1990s along with the self-sufficiency of rice production and the increasing demands of high-quality rices. During this time, considerably great, progress and success was obtained in development of high-quality japonica cultivars and qualify evaluation techniques including the elucidation of interrelationship between the physicochemical properties of rice grain and the physical or palatability components of cooked rice. In 1990s, some high-quality japonica rice caltivars and special rices adaptable for food processing such as large kernel, chalky endosperm aromatic and colored rices were developed and its objective preference and utility was also examined by a palatability meter, rapid-visco analyzer and texture analyzer. The water uptake rate and the maximum water absorption ratio showed significantly negative correlations with the K/Mg ratio and alkali digestion value(ADV) of milled rice. The rice materials showing the higher amount of hot water absorption exhibited the larger volume expansion of cooked rice. The harder rices with lower moisture content revealed the higher rate of water uptake at twenty minutes after soaking and the higher ratio of maximum water uptake under the room temperature condition. These water uptake characteristics were not associated with the protein and amylose contents of milled rice and the palatability of cooked rice. The water/rice ratio (in w/w basis) for optimum cooking was averaged to 1.52 in dry milled rices (12% wet basis) with varietal range from 1.45 to 1.61 and the expansion ratio of milled rice after proper boiling was average to 2.63(in v/v basis). The major physicochemical components of rice grain associated with the palatability of cooked rice were examined using japonica rice materials showing narrow varietal variation in grain size and shape, alkali digestibility, gel consistency, amylose and protein contents, but considerable difference in appearance and torture of cooked rice. The glossiness or gross palatability score of cooked rice were closely associated with the peak. hot paste and consistency viscosities of viscogram with year difference. The high-quality rice variety “Ilpumbyeo” showed less portion of amylose on the outer layer of milled rice grain and less and slower change in iodine blue value of extracted paste during twenty minutes of boiling. This highly palatable rice also exhibited very fine net structure in outer layer and fine-spongy and well-swollen shape of gelatinized starch granules in inner layer and core of cooked rice kernel compared with the poor palatable rice through image of scanning electronic mcroscope. Gross sensory score of cooked rice could be estimated by multiple linear regression formula, deduced from relationship between rice quality components mentioned above and eating quality of cooked rice, with high Probability of determination. The ${\alpha}$ -amylose-iodine method was adopted for checking the varietal difference in retrogradation of cooked rice. The rice cultivars revealing the relatively slow retrogradation in aged cooked rice were Ilpumbyeo, Chucheongbyeo, Sasanishiki, Jinbubyeo and Koshihikari. A Tongil-type rice, Taebaegbyeo, and a japonica cultivar, Seomjinbyeo, shelved the relatively fast deterioration of cooked rice. Generally, the better rice cultivars in eating quality of cooked rice showed less retrogiadation and much sponginess in cooled cooked rice. Also, the rice varieties exhibiting less retrogradation in cooled cooked rice revealed higher hot viscosity and lower cool viscosity of rice flour in amylogram. The sponginess of cooled cooked rice was closely associated with magnesium content and volume expansion of cooked rice. The hardness-changed ratio of cooked rice by cooling was negatively correlated with solids amount extracted during boiling and volume expansion of cooked rice. The major physicochemical properties of rice grain closely related to the palatability of cooked rice may be directly or indirectly associated with the retrogradation characteristics of cooked rice. The softer gel consistency and lower amylose content in milled rice revealed the higher ratio of popped rice and larger bulk density of popping. The stronger hardness of rice grain showed relatively higher ratio of popping and the more chalky or less translucent rice exhibited the lower ratio of intact popped brown rice. The potassium and magnesium contents of milled rice were negatively associated with gross score of noodle making mixed with wheat flour in half and the better rice for noodle making revealed relatively less amount of solid extraction during boiling. The more volume expansion of batters for making brown rice bread resulted the better loaf formation and more springiness in rice bread. The higher protein rices produced relatively the more moist white rice bread. The springiness of rice bread was also significantly correlated with high amylose content and hard gel consistency. The completely chalky and large gram rices showed better suitability for fermentation and brewing. Our breeding efforts on rice quality improvement for the future should focus on enhancement of palatability of cooked rice and marketing qualify as well as the diversification in morphological and physicochemical characteristics of rice grain for various value-added rice food processings.

This study examined physicochemical properties of rice grains and qualities of cooked white rice of the high yielding, Japonica type, specifically Druryechanbyeo and Boramchanbyeo, and of the Tongil-type, specifically Hanarumbyeo and Andabyeo. The changes of water absorption rate of rice grains, their textural properties and a sensory evaluation of the cooked rice s were analyzed. All varieties were short grain. The length and width of Tongil type rice grains larger than those of Japonica type. The water absorption of white rice grains increased rapidly until 1 hr when soaking and after that increased slightly. The water absorption of Druryechan grain was higher than that of the Boramchan. The sensory evaluation results showed that the Japonica type cooked rices had a higher value for overall quality than the Tongil type cooked rices. With regard to the textural properties of the cooked rices, the hardness of Boramchan and Hanarum varieties showed higher than that of Druyechan and Anda varieties. Adhesiveness, springiness and chewiness were not significantly different between varieties (p<0.05).

Leaf quality and fatty acid compositions of collected perilla related genus and species germplasms such as Perilla frutescens var. japonica Hara, Perilla frutescens var. acuta Kudo, Perilla frutescens var. crispa Decaisne, Perilla frutescens var. for viridis Makino, Mosla punctulata Nakai, Mosla japonica Maxim, Mosla dianthera Maxim were analysized. The number of leaves per tiller and leaf size of perilla germplasms were more and bigger than those of mosla germplasms. Aroma degree of mosla germplasms was higher than aroma degree of perilla germplasms. Mosla germplasms could be utilized in the breeding for high aroma perilla lines. Otherwise, the softness of perilla germplasms was higher than that of mosla germplasms. In case of oil and protein contents, perilla germplasms was higher than mosla germplasms, however compositions ratio of fatty acid, especially linolenic acid of mosla germplasms was higher than that of perilla germplasms, therefore mosla germplasms could be utilized as breeding materials with high linolenic acid for industrial oil. The linolenic acid with excellent quality and unsaturated fatty acid showed negative correlation with oil content, protein content and saturated fatty acids.
