  • Brown rice contains a variety of nutritional and bio-functional components compared to milled rice. However, low consumer preference for steamed brown rice and short shelf life has been implicated as deterrents to the direct consumption of brown rice. This study was undertaken to determine the effect of degree of milling (DOM) on pasting and aging properties of brown rice cultivar. Short-grain (Japonica type) brown rice cv. Boseogchal (BSC), Baegjinju (BJJ), and Hiami (HIAM) were evaluated every month during 4 months storage. Rice cultivar were categorized into waxy (BSC), medium-waxy (BJJ), and non-waxy (HIAM) of which amylose contents were 6.81%, 10.06%, and 16.69~16.72%, respectively. Peak viscosity was the highest in BJJ followed by HIAM, and BSC, showing peak viscosity was lower at low temperature storage. At storage at room temperature from 60 to 120 days, the FFA content significantly increased in the rice samples with DOM1% followed by 3% and 5%, while not significant increase in DOM0% brown rice: at 120 days, the FFA ranged in 28.35~41.48, 111.99~130.06, 76.87~91.99, and 47.13~62.37 mg KOH/100g for DOM 0%, 1%, 3% and 5%, respectively. It indicated that the fat rancidity was the least in the order of DOM 0%, 5%, 3% and 1%. Storage at low temperature could reduce fat hydrolysis with lower FFA release, but rice grain with 1% MD also released more FFA compared to the other samples. It could be assumed that the most outer bran layer, approximately 1~3%, could provide a strong protection from fat rancidity. Pasting viscosity of rice samples also increased with increasing DOM rate. Results indicated that DOM was the most significant factor for lipid rancidity during storage, resulting in high FFA formation. It suggested that brown rice with DOM 0% and/or more than DOM 5% could provide the best shelf life.

  • Meju is a basis for manufacturing Kanjang, Meju was traditionally prepared at home by different types of process depending on the regional area. It is necessary to standardize and simplify the process of Meju-preparation for Kanjang of good quality. For these purposes, the process of Meju and Kangjang making as well as analysis of commercial Kanjang, were compared. Generally, traditional Meju was prepared by steeping and dehulling the whole soybean. After steeping for 24hr. soybean absorbed water up to 110~120% of its weight. The soaked soybeans were steamed for 2hr. and cooled to 5$0^{\circ}C$. Cooked soybeans were crushed down to the size of 10~15 mesh and molded. Molded soybeans were dried for 2 days in the air, hung up by rice straw and fermented for 20~30 days under natural environmental condition. On the other hand, commercial soybean koji was made of defatted soybean. Defatted soybeans were steeped in water and steamed for 15~30min at 0.7~1.2 kg/$\textrm{cm}^2$. Steamed and defatted soybean was cooled to 4$0^{\circ}C$. Separately, wheat power was roasted at 200~30$0^{\circ}C$ by wheat roaster. Mixture of steamed defatted soybean and roasted wheat powder (5/5 to 7/3) were inoculated with 0.1~0.2% Aspergillus sojae and incubated for 2 days at 3$0^{\circ}C$ with occasional stirring. Chemical analysis showed that traditional soy sauces contained the following composition: NaCl, 20.12~25.42%; total nitrogen, 0.64~0.91%; pure extract, 9.47~11.20%; color, 2.34~4.01; pH, 4.92~5.12. Commercial products contained: NaCl, 15.20~17.19%; total nitrogen, 1.25~1.40%; pure extract, 18.17~21.47%; color, 5.41~21.12; pH, 4.51~4.66 and ethalnol. 2.97~3.12%. Organoleptic test on taste, color and flavor of traditional and commercial soysauce indicated that most of the consumers prefer commercial products to traditional products. Preferrable formulation of Kanjang based on organoleptic test of soy sauces was assumed as containing; NaCl, 16.0%; total nitrogen, 1.40%; pure extract, 19.97%; color, 12.98; pH, 4.61 and ethanol, 2.96.

  • Purpose: To increase the availability of Korean sweet potato (SP), the quality characteristics of the sweet potato pastes (SPPs) and rice madeira cake (RMC) using them were investigated. Methods: Ten different SPPs, orange fleshed Sinwhangmi, Juwhangmi, purple fleshed Sinjami and Yeonjami, Cream fleshed Sinyulmi, Sinchunmi, and newly developed Geonwhangmi, Dahomi, Daeyumi, and Pongwonmi were used. Their pastes were prepared by washed, peeled, steamed, crushed, vacuum packed and stored in a freezer until use. Results: The SPPs and RMC with them were significant difference from different cultivars with color value, rheology and texture properties, and preference test. The SPP showed the highest lightness value in Sinchunmi (55.89) and the highest viscosity in Geonhwangmi (55.33 poise). The RMCs with SPPs had lower values in hardness and chewiness than the RMC without SPP. Overall quality of preference test showed the highest values in RMC with Sinyulmi and Sincheonmi. Conclusion: The best quality of sweet potato shaped rice madeira cake was made using Sinyulmi and Sinchunmi pastes. It is suggested that sweet potato paste is possible to use as the biomaterials for application of processed foods.

  • The awareness of ritual foods in general rituals were surveyed and compared in the Gyeonggi and Gyungsangbuk-do areas in order to identify the characteristics of Korean rituals and establish desirable ritual foods. As materials for "Jeon" (fried pan cakes) in rituals, fish fillets, meat and vegetables were largely used in the Gyeonggi region. In the Gyeongbuk region, all three of these ingredients were the most highly used for "Jeon" also. In the case of rice cakes, "Songpyun" steamed on a layer of pine needles, "Jeolpyun" and "Sirudduk", with a red beans, were mostly used in Gyeonggi-do, while "Songpyun", "Jeolpyun" and "Ingelmi" were largely used in Gyeongsangbuk-do. As seasoned vegetables and herbs, fernbrakes, root of bell flowers, green bean sprouts and bean sprouts were largely used in Gyeonggi-do region, whereas, fernbrakes, bean sprouts, root of bell flowers and spinaches were mainly used in Gyeongbuk region. The use of fernbrakes was highest in both regions. With regard to the number of side dishes, 2∼3 kinds of seasoned herbs and 3∼4 kinds of fruits were mostly used, but with slightly higher numbers in the Gyeongsangbuk-do than the Gyeonggi-do region. With regard to liquor used for rituals, clear strained rice wine was used most in the Gyeonggi-do area, while more unrefined rice wine was used in the Gyeongbuk region. Meat was the most used ingredient in broth slices of dried meat and cod were highly used in the Gyeonggi region, but slices of dried squid were most widely used in the Gyeongbuk region. Most households in both regions tended not to use raw fish in the rituals, and as for the ingredients of Korean Kabobs, meat was the most widely used, then fish and finally vegetables were the most used ingredients. Beef soup was the most used, but more green vegetable soup was used in the Gyeongbuk than the Gyeonggi region. Sweet drink made from fermented rice (sikhe) was generally used in the rituals. It was the most widely used in the Chusok-Hangawi Ritual in the Gyeonggi region, while it was used in the New Year's Ritual in the Gyeongbuk region.

  • The purpose of this study was to evaluate satisfaction degree on menu served and identify food preference of the meal served to 271 business and industry foodservice workers from 4 institutions by gender difference. The demographics indicated that male(54.6%) and female(45.4%) were about an half each, mean age was ranged from 20 to 39 years old. The workers were not contented with most of menu quality attributes served from past foodservice operation. Primary complaint was improper temperature of the meal. Most workers liked meat and fish(52.1%) the most. Sensory quality evaluation from all workers was 3.37 points out of 5 points. However, female workers rated higher on the most of menu(3.72 points) compared with that of male workers(3.35 points), indicating that satisfaction was higher in the female workers(p<0.05). Mean preference of all the menu according to food type also have shown higher in female(3.52 point) than in male(3.45 point). Best food preference according to food type considering cooking method of male was given to barley rice, boiled rice with assorted mixtures, marine product stew, and Kimchi stew. On the other hand, females cared for curried rice, hash rice, and spaghetti but males have shown low preferences to those foods females liked. Also, females liked more of fried, grilled and broiled food. However, both males and females showed indifferent taste about the food cooked with steamed and stewed. From the findings, the business and industry foodservice workers were not well satisfied with menu quality considerably and differed in food preferences by gender clearly. Therefore, the manager of foodservice institution require to consider composition of gender ratio in menu preparation along with sensory quality evaluation to lead the successful foodservice management.

  • It is not known that when and by whom 'The Lee's UmsikBup' was written. This cookbook is written purely in Korean and has not been published yet. There is another book named 'UmsikBup' in the cookbooks of the Chosun Dynasty and there are many books with similar names. So this book is tentatively named 'The Lee's UmsikBup'. This book comprises fifty three items, among which there are fifteen items of rice alcoholics, three items of Gook-Su (noodles), sixteen items of side dishes, seventeen items of Tuck (rice cakes) and Guaja(kookies), and two items of fruit punch and tea. Three items were illegible because the lines were erased or the letters were not clear. The cereals needed for making rice alcoholics were sixty four percent regular rice and thirty six percent sticky rice. As for the processes, the process using Jee-ae-bop took up fifty five percent. As for side dishes, pheasants, which are seldom used for food these days, were then popular for food. And the entrails of domestic animals were much used for food. Seeing that red pepper paste mixed with vinegar was used for steamed breams (Jim) and that red pepper was used for Yeolgooja Tang, we can estimate that this book was written after red pepper was introduced. Inferring that Chohong Chang (red pepper paste mixed with vinegar and honey) is found Jinchan Ye Que, we can estimate this book was written in the late 1800's. The cereals used for making rice cakes were ninety two percent sticky rice and eight percent regular rice. Sticky rice was much more used and pepper was used for making Tuck (rice cakes) as Hun Chal Byung, So Ham Byung and Dootum Tuck. The analysis of the terms used in this book revealed that 117 items were used for cooking processes. And it also showed us that there were six kinds of cutting and thirteen kinds of heating procedure. The shapes and sizes of foods were revealed on the basis of real things. The measuring units are hard to revive since the measurements were taken by the container then in use. Thirty four kinds of containers and cookers, twenty more of which are now in use, were used for preparing foods. The use of ‘twigs stretched for the east’ had no scientific base but said something of Korean folkways at that time.
