This study investigated the quality characteristics of convenient chicken porridge prepared with fresh ginseng powder (FGP). The porridge made with the addition of FGP showed significantly higher or similar pH at 5.99-6.13 compared to porridge made without adding FGP. The convenient chicken porridge with FGP had lower viscosity and higher spreadability than the control group (p<0.05). This porridge exhibited higher lightness (L) and yellowness (b) values but a lower redness (a) value than the control group (p<0.05). The porridge made with the addition of 0.4% blanched FGP (BG0.4) displayed higher total polyphenol content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activities than the other types of chicken porridge (all p<0.05). The porridge with the addition of FGP showed weaker “rice grain size”, “glossiness”, “appearance cohesiveness”, “cooked rice aroma”, “sweet taste”, “texture cohesiveness”, “thickness”, and “stickiness” than the control group (all p<0.05). The appearance and flavor acceptance were significantly higher or similar for the porridge samples made with the addition of 0.2% non-blanched FGP (NBG0.2) and 0.4% non-blanched FGP (NBG0.4) when compared with those of the control group.

In this study, the authors investigated the quality characteristics of convenient rice porridge made from powder (PR) and half-rice (HR) sized freeze-dried cooked rice using Samgwang and Jinsumi rice. The hydration properties of the freeze-dried cooked rice and the color, viscosity, spreadability, and sensory evaluation of porridge were measured. PR showed significantly higher water-binding capacity, solubility, and swelling power than HR for both varieties (p<0.05). As a result of the quality characteristic of the porridge, PR showed significantly higher lightness, redness, yellowness, viscosity, and spreadability than HR (p<0.05). Acceptance testing showed that HR had significantly better results for all acceptance attributes than PR (p<0.05). Jinsumi HR showed better consumer acceptance for taste, texture, and overall acceptability than Samgwang HR (p<0.05). Intensity evaluations of sensory properties revealed that the Samgwang PR was more spreadable but was less chewy than Samgwang HR. Furthermore, Jinsumi HR had higher transparency, greater spreadability, and a better cooked-rice odor and savory taste than Samgwang HR (p<0.05). These results confirm that convenient porridges can be produced using freezedried cooked rice.

The purpose of this study was to investigate the changes in the content of functional components and the antioxidant activity of cooked rice and porridge composed of selected grains. The results of the study showed that brown rice and oat contained considerable amounts of γ-oryzanol (78.099~238.566 mg/100 g). However, cooked rice showed a decreased content of the same. The highest content of γ-aminobutyric acid (GABA) was observed in brown rice from Samgwang. The contents of biotin in all samples also decreased in cooked rice compared to raw cereal grains. The highest content of total polyphenols and flavonoids were observed in Heukjinmi rice, and the highest radical scavenging activity was also found in this variety. The cooking process led to a decrease in the content of functional components including γ-oryzanol, GABA, biotin, polyphenols, and flavonoids versus the corresponding raw cereal grains. These results may be useful in the development and application of home meal replacements using cereal grains.

The value of using rice flour processed into rice powder in preparing porridge was evaluated by measuring the moisture content, pH, total starch, reducing sugar, and color content. The moisture content of the rice flour and the pH of porridge made with rice flour were measured. Rice flour contained 77.55% moisture and the moisture content of the porridge made from rice flour processed into rice powder was 91.40 to 92.47%. The pH of rice flour porridge was acidic at 6.53 to 6.95. The color of the porridge was also measured. The L* values ranged from 82.62 to 97.55, the a* values ranged from －0.09 to 0.08, and the b* values ranged from －2.74 to 1.91.

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.

When producing rice products, it is very important to select suitable raw materials. Therefore, in this study, the quality characteristics of 16 rice cultivars were quantified to determine the criteria for evaluating the machinability of raw rice. The L value, which can affect the color of porridge prepared from rice, was the greatest for Hwaseonchalbyeo (84.17). The water-binding capacity, related to water interaction, was high in Hyangcheola (113.2%), and water solubility was high in Shingil (22.3%). Dodamssal (42.3%, 70.7 RVU) and Hwaseonchalbyeo (4.7%, 27.8 RVU) showed lower final viscosity compared to the cultivars in which the amylose content was medium groups (16.4~21.2%, 173.6~277.2 RVU). Specifically, cultivars with high or low amylose content had a low viscosity. The characteristics of the distribution of raw rice quality data were confirmed through 11 histograms. Furthermore, amylose content vs. water solubility, water solubility vs. peak viscosity, and peak viscosity vs. final viscosity showed high correlations (r=0.542, －0.569, and 0.836 respectively, p<0.01), and clear cultivar discrimination by the standard error of the mean (0.765~10.811). In conclusion, amylose content, water solubility, and peak viscosity were considered the most suitable characteristics for the quality evaluation of raw rice.

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.

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.

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.

Ochratoxin A (OTA) is one of the most important mycotoxins owing to its widespread occurrence and toxicity including nephrotoxicity and potential carcinogenicity to humans. Since OTA is stable under most food processing conditions, OTA has been detected not only in a wide range of agricultural commodities such as cereal grains but also their processed products. Nonetheless, it is known that significant reduction of OTA may be achieved under higher temperature and alkaline conditions. In this study, the effects of retorting cooking process on the stability of OTA in spiked (20 μg/kg of dry weight basis) rice and oat porridge (10% solid content; w/v) in the presence and absence of baking soda was investigated using a laboratory horizontal steam retort system. The samples were heated in a pot at 85°C central temperature until it becomes gelatinized, packed in retort pouched, and heat-processed in pressurized retort machine (at 121°C for 25 min) followed by drying in 50°C oven overnight. Samples were analyzed for OTA by high-performance liquid chromatography with a fluorescence detector (HPLC-FLD). The reduction of OTA in retorted rice and oat porridge were 54% and 17%, respectively, while greater reduction of OTA was observed at increased amount of baking soda. The reduction of OTA in retorted rice porridge with 0.5% and 1% baking soda were 55% and 66%, respectively. In the retorted oat porridge, reduction of OTA was also evident to result in 30% and 48% with 0.5% and 1.0% of added baking soda, respectively. These results suggest that OTA in rice and oat may be reduced significantly by retorting process. In addition, added baking soda may positively impact the reduction of OTA.

In this study, we investigated the quality characteristics and optimum conditions of porridge containing rice incubated with Phellinus linteus mycelium (PLMR). Composition measurements of PLMR were moisture 13.05%, ash 0.88%, carbohydrate 78.65%, crude protein 6.29%, and crude lipid 1.13%, also glutinous rice composition was moisture 13.99%, ash 0.32%, carbohydrate 77.18%, crude protein 7.85%, and crude lipid 0.66%. The water absorption rate of PLMR increased with increasing soaking time during 6 hours. However, the water absorption rate of glutinous rice increased until 30 minutes of soaking time. The pH of porridge was decreased as PLMR contents increased. The viscosity of porridge was increased as PLMR contents increased, and it was the lowest for the control at 914.77 cP. However, spreadability of porridge was decreased as PLMR contents increased. In terms of color, lightness was the highest for the 50% level, redness was the highest for the 75% level, and yellowness was the highest for the 25% level. In terms of textural characteristics, hardness and fracturability were increased as PLMR contents increased, whereas springiness, cohesiveness and resilience showed reverse results. In terms of consumer acceptance, flavor, appearance, viscosity, delicate taste, and overall acceptability were not significantly different between samples. Hot taste was decreased as PLMR contents increased, whereas grittiness showed reverse results. In conclusion, the results indicate that adding 25~50% PLMR to porridge is optimal for a recipe.

This study undertook to evaluate the quality characteristics of rice, to select a variety suitable for porridge. Seven varieties of rice were studied: Dabo, Daebo, Samkwang, Sindongjin, Sukwang, Jinsumi and Haiami were investigated for proximate contents and physicochemical characteristics. The moisture and crude protein contents of the rice cultivars were in the range 11.26-12.66% and 5.34-6.47%, respectively. The amylose content was the highest in the Samkwang (20.83%), and lowest in Haiami (18.32%). The water binding capacity and solubility of Samkwang and Jinsumi cultivars were greater than those of the other samples. Hardness of rice and viscosity of porridge was the least in Samkwang and Sukwang. The pH of porridge in Samkwang and Jinsumi (7.04) was higher than the other varieties (6.80-7.03). The results of this study indicate that Samkwang and Jinsumi are suitable varieties for porridge. We expect this data will be useful in the manufacturing of 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.

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.

This study was conducted in order to investigate the antioxidant capabilities and quality characteristics of instant porridge made of foxtail millet (Setaria italica Beauv.) from different varieties with different endosperm characteristics and processing using different methods. The two foxtail millet varieties used in this study were waxy foxtail millet, ‘Samdachal’, and non-waxy foxtail millet, ‘Samdame’. The means of processing food to create instant porridge were dry cereal frying, wet cereal frying, freeze drying after steaming, popping, and no treatment. The WAI (water absorption index) of instant porridge made of waxy foxtail millet was higher than that of non-waxy foxtail millet, and popping created the highest WAI among the treatments tested. Whean we analyzed RVA characteristics of non-waxy foxtail millet instant porridge, peak viscosity and setback values were decreased in all processed foxtail millet instant porridge compared to non-waxy foxtail millet instant porridge. In waxy foxtail instant porridge, the peak and final viscosities of processed treated instant porridge increased. The viscosity just after pouring hot water into the instant porridge was higher in waxy foxtail millet porridge treated by freeze drying after steaming, popping, and wet cereal frying; the viscosity of non-waxy foxtail porridge was increased after popping as compared with the other treatments. The polyphenol contents and antioxidant activities were increased in all processed, treated-instant porridge except for freeze dried porridge after steamingnt. The popping treatment showed the highest polyphenol contents (1.5 fold), and ABTS antioxidant activity (1.2 fold), compared to no treatment. Non-waxy foxtail millet porridge produced by popping earned the highest sensory evaluation scores.

The group showed the smallest of microorganism for 2.9×102 CFU/mL. On the 7 day, microorganism also found 40% added showed the smallest of microorganism for 3.1×104 CFU/mL. The color of the 20% added group, 6.74, was higher than that of the control group, 4.87, but the difference was not significant. The flavor was the in the 30% added group for 5.90, and taste was the in the 20% added group for 6.01 The control group showed the lowest preference for 4.91. The after taste was the in the 30% added group for 5.48. The viscosity of the 40% added group was higher for 5.39 than that of the control group for 5.06, no significant difference. The overall preference was rated highly, and the 20% added group showed the highest preference for 5.57.

This study was conducted to evaluate the effect of various types of functional brown rice milk porridge, which has been popular as a fast yet nutritional food, to promote rice consumption and to examine the best ratio and recipe. Each sample contained 10, 20, 30, and 40% brown rice compared to non-glutinous rice and sweet rice and were applied to mechanical and sensory tests. The moisture content of both non-glutinous rice and sweet rice porridges increased with increasing brown rice content. The viscosity of non-glutinous rice milk porridge decreased as with increasing brown rice content, whereas the viscosity of sweet rice milk porridge increased with increasing brown rice content. The pH was highest for BRT0 at 6.74 and lowest for BGT0, which is sweet rice porridge with brown rice, at 6.27. The sweetness decreased significantly for both sweet rice and non-glutinous rice porridges with the increase in brown rice content. The brightness of weet rice and non-glutinous rice porridges with brown rice increased significantly (p<0.001) with the increase in brown rice content, while the redness and yellowness of the color increased significantly (p<0.001) with increasing in brown rice content. As a result of analyzing the preference in the milk porridge containing brown rice, BRT30, which is non-glutinous rice milk porridge with brown rice, was most preferred at 5.8 in terms of color, while BRT30 was most preferred at 6.2 in terms of fragrance. All samples containing brown rice powder were highly preferred in terms of taste and the overall preference of sweet rice milk porridge was highest for BRT30 (5.8). The overall preference was highest for BGT30 at 6.1 and the preference was generally higher for the experiment groups prepared with sweet rice as opposed to those prepared with non-glutinous rice. Also, the scores for the sensory test were higher when brown rice was added. Therefore, it was concluded that the milk porridge could quickly and easily be prepared with brown rice instead of non-glutinous rice or sweet rice.
