The purpose of this study was to investigate the recent development of meat analog, industrialization, and the related legal changes worldwide. Summarizing the current status of the industrialization of meat analog, studies on plant-based meat, mycoprotein, and edible insects were mainly conducted to investigate their sensory properties (texture, taste, flavor, and color resembling meat), nutritional and safety evaluations, acquisition method of meat alternatives, and commercialization. Cultured meat is mainly studied for developing muscle satellite cell acquisition and support techniques or materials for the formation of structures. However, these technologies have not reached the level for active industrialization. Even though there are differences in the food categories and labeling between countries, it is common to cause confusion or to relay false information to consumers; therefore, it is important to provide accurate information. In this study, there were some differences in the food classification and food definition (labeling) contents for each country and state depending on the product shape or form, raw materials, and ingredients. Therefore, this study can provide information about the current research available on meat alternatives, improve regulation, and clarify laws related to the meat analog industry, which can potentially grow alongside the livestock industry.

Extended use of porcine blood in food ingredients depends on the decolorization of red blood cell concentrates and the modification of its functional properties. The purpose of this study is to compare the relative effect of cation ion exchanger for decolorization of porcine red blood globin. The globin extract is freeze-dried for determination of various functional properties, such as solubility, emulsion capability and foaming ability. Since the isoelectric point of blood globin is located at pH 6.8, which is the neutral pH ranges (6-8), so its functionalities are inferior around these pHs. This weakness has been the main reason, which limit the extended use of blood globin in food industry. Acetylation and succinylation of blood globin can be an alternative way to improve its functionalities. These results may provide new information to understand the decolorization mode by cation ion exchanger for the blood globin. With chemical, the functionalities of blood globin could be obviously improved. The above findings could enable food industry to extend the use of blood globin as a food ingredient.

This study investigated the volatile flavor components of the essential oil from Chrysanthemum coronarium var. spatiosumBailey. The essential oil obtained from the aerial parts of the plant by the hydrodistillation extraction method was analyzed by gas chromatography and gas chromatography-mass spectrometry. One hundred and one (99.11%) volatile flavor components were identified in the essential oil from the Chrysanthemum coronarium var. spatiosum Bailey. The major compounds were hexanedioic acid, bis(2-ethylhexyl) ester (12.45%), 6.10.14-trimethyl-2-pentadecanone (7.94%), 1-(phenylethynyl)-1-cyclohexanol (6.34%), α-farnesene (5.55%), phytol (4.99%), and α-caryophyllene (4.39%). When the volatile flavor components of Chrysanthemum coronarium var. spatiosum Bailey were classified by functional group, the content was high in the order of hydrocarbons, alcohols, esters, ketones, aldehydes, and phthalides. Sesquiterpene hydrocarbons were the most common hydrocarbons, mainly due to α-farnesene and α-caryophyllene. Among the alcohols, the content of aliphatic alcohols was significantly higher, mainly due to 1-(phenylethnyl)-1-cyclohexanol (6.34%) and phytol (4.99%). The analysis of the volatile flavor components of Chrysanthemum coronarium var. spatiosum Bailey in this study will provide useful information to consumers when purchasing food and to industries using fragrance ingredients.

The objective of this study was to investigate parents' behavior and attitudes regarding their kids' snacking and dietary life education. A survey was conducted with the parents (N=412) of elementary students from seven provinces, includeing Seoul, Busan, Daegu, Kwangju, Gyungnam, Chungnam, and Kangwon. Kids' snacks consisted mainly of purchased foods rather than homemade foods. Parents' main concerns regarding kids' snacks were nutrition (44.9%), taste (24.3%), and safety (23.5%). Over 50% of parents checked food labels, especially expiration date (96.4%), food ingredients (49.5%), and food additives (33.5%). The snack items frequently provided to kids were fruits (62.8%), milk (55.5%), bread (47.1%), and snack items (23.3%). Parents responded that the amount of their kids' snacking was adequate (47.8%), small (33.7%), or large (18.2%). The results show that more research is needed regarding the adequacy of kids' snacking, considering that 15.7% and 22.4% of the children ate more and less, respectively, than their daily energy requirement. 76.5% of the parents performed home education regarding their kids' dietary habits, especially on the topics of 'balanced diet' (83.9%), 'healthful food' (53.7%), and 'eating three meals a day' (40.2%). Parents obtained dietary information from TV (65.2%), internet (12.0%), and newspapers (7.0%). From this study, we found that parents perceived their kids' snacking behavior correctly, and considered home-education for their kids' dietary habits positively. However, the information resources were limited, which makes it necessary to develop parents' education programs.

The purpose of this study was to investigate foodservice management practices in the child care centers and kindergartens. Interviews were held from May to July 2008 to understand the current situation concerning foodservices in Seoul and Gyeonggi provinces. Surveys were sent out from August 2008 to April 2009 to 1,478 child care centers and 299 kindergartens via the postal service. Among them, 203 child care centers(13.7%) and 64 kindergartens(21.4%) responded. One of the largest concerns while preparing the food was nutrition(68.7%, 69.8%, respectively) followed by sanitation(24.4%, 27.0%, respectively). The most frequently referred sources for planning the menu were the Seoul child care information center(55.4%) for child care centers and kindergarten related internet sites(39.0%) for the kindergartens. In general, the child care center principal was in charge of planning the menu(40.1%). Child care centers and kindergartens purchased ingredients mostly from large retailers(55.3% and 44.7%, respectively), whereas 46.0% and 56.3% of those did through foodservice suppliers. Dietitians were rarely employed at these facilities, and this may cause unprofessional foodservice management.
