During the Joseon Dynasty, medicinal foods derived from herbs were often more effective than traditional medicines. In addition, the royal family of the Joseon Dynasty believed that foods could be used as various disease treatments. Grain-based foods, especially medicinal porridges (藥粥), were most frequently used for diet therapy. We investigated various types of diet-related diseases suffered by King Injo (仁祖) as well as how the diseases were treated using medicinal porridges based on information in the SeungjeongwonIlgi (承政院日記), which is the daily record of the Royal Secretariat of the Joseon Dynasty. This study examined the SeungjeongwonIlgi of King Injo from his1st year (1623) to 27th year (1649) on a website database maintained by the National Institute of Korean History. According to the records, King Injo suffered from severe diarrhea several times due mainly to febrile disease (煩熱症) as well as abdominal dropsy (脹滿) throughout his entire life. Major diseases affecting King Injo were due to his unhealthy eating habits and psychological factors. For treatment, royal doctors prescribed around 15 medicinal porridges, including nelumbo (seed) porridge (Yeonja-juk), milk porridge (Tarak-juk), Chinese dioscorea porridge (Sanyak-juk), mungbean porridge (Nokdu-juk), perilla seed porridge (Imja-juk), adzuki-bean porridge (Pat-juk), soybean porridge (Kong-juk), Korean-leek porridge (Buchu-juk), and so on, in addition to other medical treatments. Diet therapy using medicinal porridges has been used throughout history since the Joseon Dynasty period. However, knowledge of traditional diet therapy and medicinal porridges used by monarchs in the Joseon Dynasty is insufficient. Therefore, in-depth study is needed to understand the theory of traditional medicinal foods as well as explore their application to patients in the context of modern medicine.

The effect of solid content on the physicochemical properties of rice porridge after reheating. The concentration of rice porridge was classified as solid content (12%, 10%, and 8%) by traditional Korean cooking methods. For reheating, packed rice porridge was boiled in water for 3 min and then cooled at room temperature ($25^{\circ}C$). The viscosity, soluble solid content and reducing sugar content of the rice porridge increased according to the solid content, while the blue value decreased. After reheating, the viscosities ($25^{\circ}C$) of all rice porridges decreased to 2.9-8.4%, compared to those of freshly made rice porridge, whereas the soluble solid content and reducing sugar content increased inversely according to the solid content of rice porridge. The SDI (starch digestion index) increased according to the solid content, whereas SDS (slowly digestible starch) the lowest in the solid content 12% porridge. Based on these results, it is favorable that the viscosity decrease after reheating was to be considered to ready-to eat rice porridges preparation.

Medicinal porridge (藥粥) is made by putting rice or grains into a pot and boiling with water until a semi-liquid texture is obtained. Porridge is digested fast and absorbed by the body. Children or elderly people with weak digestive ability can eat it without difficulty. The authors of this literature focused on utilization of mung bean porridge (Nokdu-juk) based on SeungjeongwonIlgi (承政院日記), which is the daily record of the Royal Secretariat of the Joseon Dynasty from 1623 to 1910. Four cases were found. The first case used mungbean for treating fever diseases (熱症), the second as a meal alternative, the third for wound recovery, and the last case described the culture of the joseon dynasty. According to the actual cases in SeungjeongwonIlgi (承政院日記), mung bean porridge (Nokdu-juk) was actively used to lower fever and strengthen the spleen and stomach. When suffering from the after effects of a malignant tumor or serious liver disease (肝病), an infectious disease, or a serious physical wound, people ate mung bean porridge (Nokdu-juk). It is suggested that mung bean porridge (Nokdu-juk) can be used as an alternative food treatment for the current medical field due to the prevalence of pain-killers and psychotropic drug abuse.

The objective of this study was to assess the sensory-related characteristics of the broth and porridge of ready-to-eat (RTE) ginseng chicken soup (Samgyetang) with sucrose stearate added at various concentrations (0.1%, 0.2%, and 0.3%) during storage at $25^{\circ}C$ for 12 mon. Scores indicating the lightness and size of fat droplets in the broth increased during storage as the sucrose stearate concentration increased, while the clarity scores decreased until 9 mon and the taste scores decreased throughout the storage period (p<0.05). The porridge lightness increased as the concentration of sucrose stearate increased after 6 mon (p<0.05), while scores indicating the softness and vividness were higher for treated samples with sucrose stearate than for the control group after 3 mon, despite a lack of significant differences among treatment groups (p>0.05). The taste scores were lower for treated porridge samples than for the control group (p<0.05), even though no significant differences were observed among the treatment groups (p>0.05). The addition of sucrose stearate to the RTE Samgyetang broth improved the lightness (CIE $L^*$) value of the broth and various sensory palatability parameters, including the color and fat droplet size of the broth and the softness and vividness of the porridge, despite reductions in broth clarity and taste scores for the broth and porridge during storage.

We investigated the physicochemical and antioxidant activity characteristics of tomato porridge with different ratios (0%, 2%, 4%, 6%, and 8%) of tomato powder in order to determine its potential health benefits. Tomato porridge samples were measured to obtain 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity. The DPPH radical scavenging activity increased with the addition of tomato powder. The moisture contents of samples ranged from 81% to 78%. The L-value decreased, while a- and b-values increased, as the amount of tomato powder in the porridge increased. Also, the pH of samples decreased with increasing quantity of tomato powder. Based on sensory evaluations, the tomato powder intensified color, flavor, taste, appearance, viscosity and overall acceptability of the porridge. The sample that comprised 6% tomato powder had the highest color, flavor, taste, appearance and overall acceptability scores. Consequently, this research found that incorporating this percentage of tomato powder into the rice flour was the best formula for tomato porridge.

The aim of this present study was to evaluate the effects of gamma-irradiation on the microbial and physicochemical characteristics of the rice flour porridge. The viscosity of the gamma-irradiated rice flour porridge was decreased as compared to that of the control. The soluble solid and reducing sugar content of the rice flour porridge was increased according to the gamma irradiation dose, while the blue value was decreased. From the results of a DSC curve, it was suggested that gamma irradiation delayed the retrogradation of the cooked rice flour porridge. The sensory score for overall acceptance and the chewing times for swallowing of the porridge, decreased with gamma irradiation doses above 3 kGy. Based on these results gamma irradiation may significantly enhance the swallowability of rice porridge, especially for elderly or infant subjects who have decreased mastication. However, more research is needed to improve the sensory qualities for the industrial application.
