Objectives: With the increasing number of single households and so-called Honbab-jok, those who eat alone, people tend to enjoy convenient and simple meals, such as single dish meals. This study was performed to provide data on the energy and nutrient content, and nutritional adequacy of single-dish meal. Methods: From the literature reviews, 61 types of single-dish meals were selected, and divided into 4 groups (steamed rice, noodle, porridge, and sandwich burger), and a further 11 sub-groups (bibimbab, fried rice, topped rice, rolled rice/ warm noodle, cold noodle, seasoned noodle, dukgook/ porridge/, and sandwich, burger). In addition, 382 junior high school students from Gyeonggi, Sejong, Jeonbuk, and Chungnam areas were recruited for the survey. The survey questionnaires were composed of the characteristics, preference, and intake frequency of single-dish meals. The representative energy content (arithmetic mean) of single-dish meals were calculated, and compared with the energy contents of preference and intake frequency-weighted values adjusted. The representative nutrient contents, energy contribution ratio, and INQ (index of nutritional quality) of a single-dish meal were calculated for a nutritional adequacy evaluation. Results: The study subjects considered a single-dish meal as tasty, simple and fast to prepare, inexpensive, nutritious, and no low calorie food. The preference scores of all but 1 sub-group of singledish meals were ${\geq}5.00$ (5.00~5.97), and 1 sub-group (porridge) was 4.67 on a 7-point scale. The intake frequency of 11 sub-groups were 0.31~1.71/week, porridge was the lowest at 0.31 and warm noodles was the highest at 1.71. Fried rice, rolled rice, and warm noodle' intake frequency were ${\geq}1/week$. The representative energy of steamed rice, noodle, sandwich burger were 443, 429, and 428 kcal, respectively, and that of porridge was 264 kcal. Less than 5% differences in the representative energy of 4 groups were observed when adjusted for the preference or intake frequency-weighted values. The energy contribution ratio of macro-nutrients calculations showed that porridge was a high carbohydrate and low fat food, whereas sandwich burger were high fat and low carbohydrate foods. The INQ of calcium and vitamin C were less than 1.0 in all 4 food groups, but the INQ of protein and thiamin were > 1.0 in all 4 single-dish food groups. Conclusions: The representative energy in the 4 groups of single-dish meal was 264~450 kcal, which is a rather low calorie meal, and the energy contribution ratio of macro-nutrients were inadequate. The protein and thiamin levels were sufficient but the calcium and vitamin C levels were insufficient in all 4 groups of a single-dish meal judged by the INQ. The additional intake of fruits and milk dairy products between meals with a single-dish meal, supply of calcium and vitamin C may increase, which will result in an improved nutritional balance.

The effects of chlorophyll (0.33 mg/kg) and ${\beta}$-carotene (3.3, 9.9, 19.8 mg/kg) addition to a mixture of roasted perilla seeds, rice, and water (30:45:225, w/w/w) on the lipid oxidation and tocopherol contents were studied during heating at $100^{\circ}C$ for 120 min to simulate cooking of perilla and rice porridge. Lipid oxidation was evaluated with peroxide values (POV) and conjugated dienoic acid (CDA) values, and chlorophyll, ${\beta}$-carotene, and tocopherols were determined by HPLC, POV, and CDA values were increased during heating, indicating the occurrence of lipid oxidation in the perilla and rice porridge. ${\beta}$-Carotene decreased the POV and CDA values of the samples in a concentration-dependent manner, while the addition of chlorophyll did not affect them. Chlorophyll and ${\beta}$-carotene which were added, and tocopherols naturally present in samples were degraded, following the first order kinetics during heating, and ${\beta}$-carotene protected tocopherols from degradation.

We investigated the physicochemical properties of brown rice by cultivar to select cultivar suitable for making brown rice porridge. The moisture content of the brown rice ranged from 8.79~11.78% with the highest varieties being 'Geonyangmi'. The crude ash and crude lipid content ranged from 1.02~1.65% and 1.65~3.26%, while the rest were similar except for 'Daebo'. Crude protein also had the lowest 'Daebo' and generally glutinous rice showed higher crude protein content than common rice. The hardness showed that 'Seolgaeng' and 'Keunnun' were the lowest, and 'Haiami' was the highest. In the RVA analysis, the setback was in the range -80.61~22.44 and was low in the order of 'Wolbaek', 'Baekjinju'', and 'Dongjinchal'. As a result of water binding capacity (WBC) measurement, 'Sindongjin', 'Geonyang' and 'Samkwang', were high in common rice, and 'Dongjinchal' and 'Hwaseonchal' were high in glutinous rice. Generally, solubility and swelling power in common rice was found to be lower than in glutinous rice. As a result, 'Samkwang' is considered suitable for brown rice porridge production because of high WBC, breakdown, and low setback.

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 feasibility of reduction of sodium intake using sun-dried salt and monosodium glutamate (MSG) was studied. Preference test was performed to evaluate the sensory properties of bean-sprout soup and vegetable rice porridge soup. Sun-dried salt and MSG might be a partial substitute for refined salt. There was a significant difference in salt taste strength between sun-dried salt and refined salt. Sun-dried salts 0.45% with MSG 0.07% resulted in the highest taste preference compared to that of sun-dried salts 0.60% without MSG in bean-sprout soup, which resulted in 23.9% reduction of sodium intake. Sun-dried salts 0.38% with MSG 0.04% resulted in the highest taste preference compared to sun-dried salts 0.53% without MSG in vegetable rice porridge soup, which resulted in 25.4% reduction of sodium intake. There seemed to be a synergistic effect on reduced usage of sodium salt when MSG was used in vegetable rice porridge and bean-sprout soup with sun-dried salt.

This study optimized the vegetable rice porridge preparation process with Israeli carp Cyprinus carpio (VRP-IC). The optimum heating period for Israeli carp paste (IC-P) in a retort was 120 min as per yield results. Response surface methodology was performed with IC-P/[rice (glutinous rice: non-glutinous rice=6:4) (Rice, RI)+vegetable (carrot: zucchini=1:1) (vegetable, VE)] (X₁) and RI/VE (X₂) as independent variables; viscosity (Y₁), hardness (Y₂), amino nitrogen (Y₃), and overall sensory acceptance (Y₄) as dependent variables. Optimum rates of IC-P, RI, and VE were 47.37%, 24.49%, and 28.15%, respectively; predicted multiple response optimum values for the dependent variables were 20,150 mPa·s, 2,002.9 N/m2, 193.1 mg/100 g, and a 6.4 score for Y₁, Y₂, Y₃, and Y₄, respectively. Under optimum conditions, experimental values for Y₁, Y₂, Y₃, and Y₄ were 20,359.8±191.9 mPa·s, 2,015.0±9.6 N/m2, 188.1±4.9 mg/100 g, and a 6.5±0.2 score, respectively, which were not significantly different from the predicted values (P < 0.05). Results of F0 value, viscosity, hardness, volatile odor intensity, and browning suggested that the optimum sterilization period was 25 min. VRP-IC prepared under the optimum conditions was superior to commercial vegetable rice porridges in sensory evaluations.

The effect of mixing ratio of materials and their retort processing conditions on the physical properties and preference of oyster porridge were investigated. Rice gave adequate viscosity (about 800 cp) to the porridge as it was used 10～12% level and half of it was ground. Potato starch, waxy corn starch, and Perfectamyl AC showed small variation in viscosity unrelated to the temperature, that was a good condition for high quality porridge. Especially, waxy corn starch had a good property for retort porridge because its viscosity was maintained high during the processing and decreased to preferable one after processing. Purity CSC, modified starch gave gum-like texture and didn't cause water-separation much after freezing and thawing treatment of the porridge. Therefore, it was good for enhancing the physical property of the porridge as a co-additive of waxy corn starch when it was used at quarter level of waxy corn starch. Xanthan gum increased dispersibility of materials and it was useful for stabilizing physical quality of the porridge without affecting preference when it was used below 0.2% concentration. As a result, the optimal material-mixing ratio was determined as rice 10% (50% of it was ground), waxy corn starch 1.5%, Purity CSC 0.5%, xmthan gum 0.2%, salt 0.3%, and water 87.5%. Oyster's porridge, retort processed with this recipe, showed stable physical property after 6 month storage at room temperature.

Objectives : This paper studies how the people of the past deal with constipation before the introduction of modern medical knowledge. Then, the paper selected some of the methods that use food ingredients with little to no side effects, and studied them to find a basic set of data that can be applied to today's medical practices. Methods : This paper reviewed six literatures: China's Eumsunjungyo, Nonohangeon, and Shiggamboncho, and Chosun's Singnyochanyo, Donguibogam, and Jejungsinpyeon. The food cures related to constipation were studied to discover what ingredients and preparation forms were used, how they were taken, what types of prescriptions existed, and how they were applied. Results : The food cure for constipation included ingredients such as mazi, suzi, sesame, honey, yiyiren, yuliren, xingren, taoren, and rice. These ingredients are known for replenishing the body's fluid and humor and allowing the better flow of qi. Mazi porridge, suma porridge, raw sesame oil, suzhu porridge, and suxing porridge were effective in dealing with the conspitation caused by heat, and jingshen wan, yiyiren porridge, yuliren porridge, yulirenyiyiren porridge, xingren porridge, and taoren porridge were effective in taking care of conspitation caused by qi deficiency. Conclusions : With a constipation caused by heat, it is good to take mazi and spinach regularly which is helpful in cooling down the heat. For senior citizens, constipations occur due to the qi deficiency that leads to the lack of fluid and humor. In this case, suzhu porridge should be taken regularly together with milk and sesame oil in order to replenish the qi. This will tonify the amount of qi and moisten the large intestines, which will be also helpful in tonifying the body itself.

For increasing both the viscosity and intake of calories and nutrients, four cereal powders: Goami (GR), waxy barley (WBL), germinated brown rice (GBR), and oat (OT) were added to rice porridge, and the properties of the porridge were compared with that containing a commercial thickener. Among the samples, the porridge with WBL showed the highest viscosity, whereas that with GR showed the lowest. With regards to color properties, the porridge with GR showed the highest whiteness, while those with OT or GBR had the highest yellowness, affecting the color of the rice porridge. The viscosity level of porridges with cereal powders did not reach that of the porridge with the commercial thickener at $90-95^{\circ}C$; however, at $55-60^{\circ}C$, the viscosity of the porridge with cereals was enough to replace the commercial thickener. With regards to organoleptic tests, the overall acceptability was mainly attributed to color, and there were no significant differences in other properties. From these results, it seems that the cereal powders could be suitable substitutes for commercial thickeners.

This study was conducted to explore the quality characteristics of colored rice depending on the cultivars (Jeogjinu, Josaengheugchal, Joeunheukmi, Heukjinjubyeo, Hongjinju, Heukjinmi, Geongganghongmi) for porridge. The moisture, crude protein, lipid, ash, amylose and damaged starch contents of colored rice ranged from 10.05~11.23%, 7.72~8.69%, 2.68~3.26%, 1.62~1.88%, 6.29~20.31% and 5.06~8.26%, respectively. The highest moisture (11.23%), crude protein (8.69%), lipid (3.26%) and ash (1.88%) contents of colored rice were detected in Heukjinjubyeo, Joeunheukmi, Josaengheugchal and Heukjinmi, respectively. The lowest amylose and damaged starch contents of colored rice were detected in Josaengheugchal and Joeunheukmi, respectively. In general, the water binding capacity, water solubility and swelling power of Heukjinmi were greater than those of the other cultivars. The investigation of the pasting properties (peak, trough, break down, final and setback viscosity, peak time, pasting temperature) of colored rice indicated a low value in Josaengheugchal. The lowest hardness (13,673.25 g) of colored rice was observed in Heukjinjubyeo while the highest digestibility (5.44 glucose mg/g) of colored rice was observed in Josaengheugchal. These results indicated that Josaengheugchal are suitable cultivars for porridge.
