The purpose of this study was to derive the conditions for manufacturing rice porridge with optimum properties after reheating. The characteristics of rice porridge according to the soaking time, water addition rate, heating temperature, heating time, and cooling conditions were compared using the 'Samkwang' cultivar. In Step I, as the heating temperature increased, the weight change decreased and the viscosity increased, and the temperature known as the main factor of the gelatinization also appeared to affect the viscosity increase. In Step II, the viscosity and the texture properties was not significantly different as the soaking time was reduced, and 10 minutes was suitable because of due to the shortening effect of the total process time. In Step III, the residual heat was lowered by cooling after the rice porridge production, so the viscosity could be greatly reduced. Also, it was confirmed that the water addition rate of 900% and the heating temperature of 15 minutes were optimal manufacturing conditions. The next study will investigate the porridge processability of rice cultivars using these results.

This study researched the food culture and bean economy of the Joseon dynasty during the 16th century and according to the primary lifestyle reference "Shaemirok (?尾錄)". The research analyzed the textual contents of the "Shaemirok (?尾錄)". It is clear that the people of the Joseon dynasty produced more beans than grain, at a ratio of 41 to 50, respectively. The soy bean sauce consumption was split into family consumption and non-family consumption. It was evident that there was more family consumption compared to that of non-family consumption at a ratio of 7 to 3, respectively. People of the Joseon dynasty annually recorded their way of making soy sauce from 1595 to 1600. The Joseon writers edited the record six times for making meju and four times for making soy sauce. The recorded ratio displays the ingredients of soy sauce, which were: 6 Du of Mal Jang and 2 Du of salt. Mal Jang and salt had a three to one ratio, respectively. The most mentioned food was Tofu during the mid-Joseon period with fifty six mentions. The Joseon people regarded making Tofu in a Buddhist temple as a family-bonding experience. Porridge was the second most prominent food next to Tofu, among the bean-related food. Porridge appears thirty five times. There were 3 types of porridge named: bean porridge, bean powder porridge and mung bean porridge.

The purpose of this study was to investigate changes in the cooking process of $Pat-juk$(red beans porridge), $Jat-juk$(pine-nut porridge) and $Tarak-juk$(milk porridge) in cooking books published after Korean modern era, approximately from late 19th century to the present. We analyzed 11 historical cook books were analyzed. It is found that the amount of red beans used for $Pat-juk$ was the same or more than that of rice but never less than rice. Only one cook book suggested sugar as seasoning for final taste, but all the other cook books mentioned salt for final taste. $Hangukeumat$(1987) suggested the method for obtaining optimum color for $Pat-juk$. After smashing and passing through the cooked red beans, collecting the red bean water to boil first and then adding the passed through red beans to boil together, in which rice will be added the last to be boiled. For $Jat-juk$, the ratio of the amount of pine-nut and rice were varied among cook books that the amount of pine-nut can be more, same or less than rice. $Jat-juk$ can have salty or sweet, so sugar, honey or salt were used for final seasoning. Pine-nut and rice were cooked together or cooked successively depending on cook books. The changes in cooking procedures of $Tarak-juk$ were the portion of milk used and the method of preparing rice before making the porridge. Firstly, the portion of milk increased over time. $Tarak-juk$ can be also tasting both sweet or salty, so sugar or salt was used for final seasoning. Secondly, two method of preparing rice were found; one is that rice was ground after soaking in water and the other is that rice was ground and toasted before putting into the porridge. When the ground rice was toasted, the milk was added with water at the same time because the cooking time of the porridge with toasted rice was shortened so that the milk could be added earlier than the other method without the risk of sticking on the bottom of the pot. In further studies, the cooking procedures used in the previous period of the late 19th century should be examined. Also after restoring all the cooking methods suggested in cook books, the comparison of the sensorial and nutritional value needs to be carried out for applying or reinventing new recipe for food industry.

점도 상승 효과와 열량 및 영양성분의 섭취량 증가를 목적으로 고아미, 찰보리, 발아현미, 귀리 등 4종 곡류를 이용, 시판 증점제와 유사한 점도를 갖는 첨가량을 결정하고, 시료의 점도, 색도, 관능적 특성 등을 평가하였다. 곡류들 중, 찰보리가 가장 높은 호화 점도 특성을 보였으며, 고아미가 가장 낮은 특성을 보였다. 색도측정 결과 고아미는 명도가 가장 높았고, 귀리나 발아현미는 황색도가 높아 첨가한 시료의 노란색이 두드러지는 특성을 보였다. 시판 증점제 첨가량을 기준으로 분산매인 흰쌀죽 시료의 점도를 비교한 결과, 시판 증점제 0.5포 첨가 점도, 즉 1단계 점도를 얻기 위해서는 고아미 3%, 찰보리 3%, 발아현미 4%, 귀리 3.5%를 첨가해야 하고, 시판 증점제 1포에 해당하는 점도 2단계에 도달하려면 고아미 6%, 찰보리 4%, 발아현미 5.5%, 귀리 5%를, 2포에 해당하는 점도 3단계는 고아미 7%, 찰보리 5.5%, 발아현미 6%, 귀리 6.5%를 첨가해야 도달할 수 있었다. 온도에 따라 증점제 첨가시료의 점도는 달라졌으나, 배식과 섭취온도를 고려한 $55-60^{\circ}C$에서는 시판 증점제를 대체하기에 충분한 점도를 보였다. 관능검사결과 전체적 선호도는 주로 색에 기인하였으며, 다른 요인들은 관능적 특성에 차이가 없는 것으로 나타났기 때문에 감각적 특성이 20-30대보다 민감하지 않은 연하곤란자(주로 노인)의 경우, 그 차이가 적을 수 있어 본 실험에서 사용한 곡류 가루들은 충분히 시판 증점제를 대체할 수 있을 것으로 생각된다.

In this study, the product characteristics and physicochemical properties were investigated through collection of commercial porridge. The addition rate of grain raw materials was about 6.5~11.75%, glutinous rice was added at a rate of about 23~60% to improve the viscosity and various other food additives were used. The moisture content characteristics varied among the products. The rotational viscosity of CP (Commercial Porridge)4 was the highest at 39,054 cP, while the flow viscosity of CP3 was least at 4.80 cm/30 seconds. The starch content differed among the products in the range of total starch 6.96~8.08%, amylose 1.41~2.61%, total sugar 6.55~12.81% and reducing sugar 0.50~0.99%. Particularly, total sugar showed a very high correlation (-0.920) while rotational viscosity and color value (b) showed significant correlation with most of the properties i.e. moisture, solids content etc. There was a rapid increase in the reactivity of starch degrading enzyme at the early stage of the reaction which gradually decreased with time. The physicochemical characteristics of commercial porridge presented in this study could be expected to increase the industrial use value of the related research because it considers the quality of the currently commercialized porridge for the future selection of suitable porridge raw materials.

The effects of sucrose stearate at various concentrations (0.1%, 0.2%, and 0.3%, w/v) on the physico-chemical characteristics of ready-to-eat (RTE) Samgyetang were investigated during storage at $25^{\circ}C$ for 12 mon. Over the storage duration, the addition of sucrose stearate had no significant effects on the proximate composition of Samgyetang, including meat, broth, and porridge, or the hardness and spreadability of the porridge, although it resulted in significantly higher CIE $L^*$ values for the porridge. The CIE $L^*$ values of Samgyetang porridge with added sucrose stearate increased until 9 mon, while the control decreased until 6 mon, and the values for both changed insignificantly thereafter. The breast meat of Samgyetang treated with sucrose stearate showed higher percentages of polyunsaturated fatty acid after 3 mon and lower percentages of monounsaturated fatty acid after 6 mon compared to the control (p<0.05), while no significant differences were observed with the different sucrose stearate concentrations (p>0.05). The overall sensory acceptability scores were higher at sucrose stearate concentrations of 0.2% or 0.3% after 6 mon and at 0.1% after 9 mon compared to those of the control.
