This study aimed to investigate the acrylamide content in frozen food products after cooking. Twenty samples of bread (Group 1) and 30 samples of processed tuberous and corn vegetable products (Group 2) were selected. Acrylamide levels were quantified using liquid chromatography tandem-mass spectrometry (LC-MS/MS). The frozen food samples were heated using the air fryer cooking method according to the product packaging and were compared to ready-to-eat French fries (Group 3). The results showed that the acrylamide content was the highest in group 3, followed by that in group 2 and group 1. The acrylamide content of all the samples was found to be within the domestic recommended standard of 1 mg/kg. However, when the samples that exceeded EU benchmark level (0.5 mg/kg) were selected and cooked using the deep-fat frying method according to the product packaging, one of them showed the acrylamide content of 1.83 mg/kg, which exceeded the domestic recommended standard. The present study highlights the need for continued evaluation and management to reduce acrylamide contents in frozen foods, as increasing domestic exposure to acrylamide is concerning.

A chitosan-degrading fungus, BSF114, was isolated from soil. The culture preparation showed strong chitosanolytic enzyme activity at an optimum pH of 4.0 and optimum temperature of $60^{\circ}C$ after 36-40 h fermentation. The rapid decrease in the viscosity of the chitosan solution early in the reaction suggested an endo-type cleavage of the polymeric chitosan chains. To identify the isolated fungus, molecular biological and morphological methods were used. The fungal internal transcribed spacer (ITS) region 1 was amplified, sequenced, and then compared with related sequences in the GenBank database using BLAST. The phylogenetic relationships were then analyzed, and the results showed that the fungus belongs to Aspergillus fumigatus. Morphological observations were also used to confirm the above conclusion. The chitooligosaccharides (COS) obtained through hydrolyzing the colloidal chitosan showed that A. fumigatus BSF114 is suitable for degrading chitosan and producing chitooligosaccharides on a large scale. High concentrations of the COS (1,000 and 500 ${\mu}g/ml$) significantly proliferated mice marrow cells.

This study was performed for both evaluating the safety of other processed products and providing basic information for making the general standard for contaminants in the category of other processed products. We analyzed the contents of three heavy metals, thirty six anti-impotence drugs and their analogues, three anti-obesity drugs and their analogues, twenty eight steroid drugs and their analogues, collecting in Incheon Metropolitan City. Any illegal compound was not detected in those products. However the contents of lead, cadmium and mercury of those products were at the range of 0.001-13.390 mg/kg, 0.03-1.231 mg/kg and 0.001-0.650 mg/kg respectively. Because there are no standards of heavy metals against other processed products, we compared the analytical results with relevant standards of both S. Korea and foreign countries. As a result, two products exceeded the relevant standards of lead, and other two products exceeded the relevant standards of mercury. The relative hazards compared to PTWI of FAO/WHO (Codex), Seafoods-pajeonmix, Perilla seed powder exceeded PTWI standards 0.214. The compulsory standards of each food product are determined by the category of the products. Because there is no standard of heavy metals in the category of other processed products in S. Korea, any food products registered as other processed product by manufacturer are free with those standards. Abusing similar problems on the categorization of food products could cause consumers' health problem. To prevent these problems, detail regulations on the categorization of food products have to be introduced.

This study investigated the possibility of reducing sodium and sugar intake in the Bulgogi bowl and yogurt, respectively, by utilizing food and non-food factors. Sodium and sugar replacers were the target food factors, and eating environment was the target non-food factor. The sodium content of Bulgogi bowls was reduced by 40%, and a flavor enhancer was applied to compensate for the reduced saltiness. Low calorie sweeteners, such as sucralose and stevia, were used to lower the sugar content of yogurt by 30%. Consumers were asked to evaluate the samples in one of the three eating environments: private booth evaluation, BOOTH; watching video clips during evaluation, VIDEO; conversation with friends during evaluation, FRIEND. The results showed that applying sodium or sugar replacers were effective in lowering sodium or sugar intake, respectively, without compromising the acceptance level of samples. Significant influences of the eating environment were observed on liking and perception of samples, but the influence patterns were not consistent between Bulgogi bowl and yogurt.

The purpose of this study was to examine the level of importance of service quality provided by restaurant when industry meal service recipients used the restaurant. Additionally, the purpose was to compare the level of satisfaction on the respective service qualities of company cafeteria and outside restaurant. The level of relative importance and satisfaction of service quality attributes are comparatively analyzed using the Important-Performance Analysis (IPA) of customers in order to provide basic information on the direction of marketing to efficiently operate company foodservice facilities. Restaurant service qualities were divided into the six factors of hygiene, convenience, food, environment, subsidiary services and food distribution process. The results revealed that the 'environment' of both company cafeteria and outside restaurant was needed to improve as quickly as possible. Additionally, it was found that the level of satisfaction was higher in the 'food' and 'environment' factors when using company cafeteria and outside restaurants, which would become an important attribute for the company foodservice recipients to use outside restaurants than using company cafeteria. Accordingly, it could be said that company cafeteria will need further control of the 'food' and 'environment' factors.
