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.

This review explores the factors that improve meat protein digestibility and applies the findings to the development of home meal replacements with improved protein digestion rates in older adults. Various methods improve the digestion rate of proteins, such as heat, ultrasound, high pressure, or pulse electric field. In addition, probiotics aid in protein digestion by improving the function of digestive organs and secreting enzymes. Plant-derived proteases, such as papain, bromelain, ficin, actinidin, or zingibain, can also improve the protein digestion rate; however, the digestion rate is dependent on the plant enzyme used and protein characteristics. Sous vide processing improves the rate and extent of protein digestibility, but the protein digestion rate decreases with increasing temperature and heating time. Ultrasound, high pressure, or pulsed electric field treatments degrade the protein structure and increase the proteolytic enzyme contact area to improve the protein digestion rate.

When it comes to the development of a retail market, it has not only influenced the supply and sales of seafood, but it has also led to considerable changes in consumers' purchasing behavior and purchasing purposes. As consumers' incomes and lifestyles have improved, the tendency to purchase seafood has rapidly changed. In addition, the increase in two-income family incomes that resulted from women's active participation in society has increased the number of consumers purchasing home meal replacements (HMR) or convenience food rather than original food. With these changes in social-economic background and in consumers' needs, the purchase of seafood is gradually changing. As a result, companies are constructing diverse marketing strategies to satisfy their needs. Companies' marketing strategies have an immediate and vital effect on consumers' purchases of seafood. The most important and fundamental role is providing an opportunity for consumers to choose what to buy by being giving information and knowledge. In this paper, the purchasing behavior of consumers buying seafood will be examined with respect to their knowledge. First, which factors among a diverse range of marketing strategies exerted a significant impact on consumers' objectives and subjective knowledge was examined. Second, the study investigated which knowledge factors were important in influencing attitudes and purchasing purposes based on knowledge level. By comparing and analyzing factors related to consumers' knowledge with respect to seafood purchases, information is provided to inform companies about efficient strategies for marketing tactics.

Objectives: This study examined the problems encountered when analyzing the market size, purchase, and consumption of HMR (home meal replacements) in the Republic of Korea. Methods: The macro data relevant to the market size and purchase status of HMR were critically summarized. The micro data retrieved from the 2019 & 2020 Korea National Health and Nutrition Examination Survey (KNHANES) were analyzed to understand the consumption of HMR. Results: The Korea Agro-Fisheries & Food Trade Corporation and the Ministry of Food and Drug Administration reported the market size of HMR, whereas the Korean Rural Economic Institute and the Rural Development Administration reported the purchase expense and frequencies of HMR. Since the values on the market size and purchase status were calculated or surveyed using different scopes of HMR, there have been reliability issues for the data presented. Additionally, lack of consensus on the use of Korean terms corresponding to HMR was found to be a problem. To examine the consumption of HMR, analysis of the food intake data from KNHANES presented results with very low validity due to the inappropriate survey and coding scheme not reflecting the inclusion of new food types. Conclusions: Several problematic discrepancies were encountered in the statistics on HMR. The fundamental cause of these problems was the absence of agreement on the scope of HMR and the Korean terms corresponding to it. Considering the increasing importance of HMR in Korean diets, urgent cooperative efforts are required between the government and academia to derive an agreed Korean term and establish the scope of HMR.

Commercial boiled frozen ark shell Scapharca subcrenata (BFAS) is generally used as a seasoned seafood products. One problem facing the industry is that quality decreases during thawing. This study investigated ways to improve quality and shelf-stability of BFAS for use as a non-thermally prepared seasoned seafood products. The Viable bacteria were detected in BFAS after thawing under running water, but were not detected after blanching for over 2 min at 95±5℃. Blanching and dewatering times were optimized by response surface methodology (RSM) to reduce the initial number of bacteria and improve BFAS texture. Experimental design was deemed appropriate because no significant difference (P>0.05) was observed between predicted and actual moisture content, hardness, and overall acceptance values. Optimal blanching and dewatering times were 210 s and 80 s, respectively. Optimized blanching and dewatering processes can significantly improve safety and BAFS qualities including texture. These results indicate that BFAS demand as a staple for home meal replacements can be increased by application of optimized blanching and dewatering processes, especially in Korean seafood processing companies where running water thawing is common.

This study examined Tthe cooking methods foroftraditional foods called such as Mieum, Misu, and Goeum from the from investigation of old cook books and ancient literatureis as follows. There We found were 7 types of Mieum that were cooked by mixing rice and cereals, while 3 types of Mieum were cooked by mixing cereals and herbal medicines to with thenuts. The Mieums that were cooked by mixing meat, fish, and shellfish, etc. to the herbal medicine ingredients like such as medical plants, etc were consisted of 8 types. Therefore, a total of 18 types of Mieum, Misu, and Goeum, etc were have been classified. Among the cooking methods of for Mieum, rice and grains were boiled for an extended longtime and filtered with a sieve to be used as the juicebroth. The Job's tears and millet, etc were mixed into water, or boiled after being made into a powder, soaked into water, and dried. The herbal medicine ingredients such as ginseng were boiled for an extended long time, and once the ingredients are were flown out cooked down, it the broth was filtered with asieve to be used the as a liquid extract. The meat, bone, and shellfish, etc were also boiled for a longn extended time, filtered with a sieve, and made into a juice broth to be used as a drinks from on occasion time to time. These drinks, called Mieum, Misu, and Goeum above, were healthy foods our ancestors used to enjoy for enjoyment drinking, and were also food for remedyies and sources of nutritionon. As Since the meal replacement foods to that replace meals that can be eaten right away while working and studying are needed, due to is required within the our busy schedules of in modern peoplesociety, thise literary investigation and the cooking methods for of Mieum, Misu, and Goeum, which that used to be are our traditional foods, can be are used as a basic research material for the development of convenient breakfast to meal replacements breakfast.
