Recently, many cases related to viral gastroenteritis outbreaks have been reported all over the world. Noroviruses are found to be leading as the major cause of outbreaks of acute gastroenteritis. Patients with acute gastroenteritis are normally found to be positive with norovirus when the stools and vomit are analyzed. This paper reviews various activities and previous reports that describe norovirus contamination in various food matrixes and the relationship between food handlers. Lately, a numbers of norovirus outbreaks have been reported that are involved with fresh produce (such as vegetables, fruits), shellfish, and prepared food. Food produce processed by infected food handlers may therefore become easily contaminated. In addition, foods that required much handling and had been eaten without heat treatment gave the high risk for getting foodborne illnesses. The standard method for detection of norovirus has already been available for stool samples. However, only a few methods for detection of norovirus in food samples have been developed until now.

Smart HACCP is a system that can check the monitoring of critical control point (CCP) in real time to implement improvement measures immediately after departure from limit criteria and prevent falsification of data by digitizing handwritten records. In this study, we developed the analysis model for the effectiveness ofsmart HACCP to compare and analyze with existing HACCP. By introducing of smart HACCP system, the evaluation index value of HACCP effectiveness for HACCP-certificated companies on a small scale increased by 9.25 points, corresponding to 11.52% of increase rate. General HACCP-certificated companies showed 4.52 point and 5.00% of increase rate by introducing of smart HACCP system. Thus, it was confirmed that the introduction of smart HACCP system contributes to the improvement of food safety management and especially it would be more effective for HACCP-certificated companies on a small scale than general HACCP-certificated companies.

When manufacturing Alaska pollack Gadus chalcogrammus surimi for 3D printing, it examined the characteristics of physical properties and sensuality by adding polysaccharides alginic acid [0, 1, 2, 3% (w/w)]. As a result of the color value of surimi by adding alginic acid, it showed that the lightness of heated surimi containing 2% (w/w) alginic acid was the highest and ∆E value was the lowest. In the changes in physical properties, the heated surimi of 3% (w/w) alginic acid content showed the lowest values of hardness, springiness, cohesiveness, gumminess, chewiness and resilience, but the highest adhesiveness. In the case of fried surimi, its hardness, cohesiveness, gumminess, chewiness and resilience were the lowest at the content of 3% (w/w) alginic acid. After 7 days of cold storage, the hardness, gumminess, and chewiness of heated surimi with an alginic acid content of 2% (w/w) were significantly higher, and fried surimi was also the same. In the results of the sensory evaluation, there were significant differences according to the alginic acid content in hardness and fishy smell, and as the alginic acid content increased, it felt more fishy smell, resulting in poor preference.

This study examined the effects of additives on the physical properties of surimi made from Antarctic krill Euphausia superba. Krill surimi was prepared from krill meat with an added cryoprotectant (sugar 6%, polyphosphate 0.2%). Krill surimi without additives does not form a gel. In order to enhance the gelling of krill surimi, additives such as soy protein isolate (SPI), guar gum, carrageenan, and wheat starch were examined. Of these, SPI had the highest gel-forming activity, while guar gum, carrageenan, and wheat starch had decreasing gel-forming activity and negative effects on other physical properties as their concentrations were increased. In addition, SPI enhanced the gel strength and physical properties of krill surimi. The fluoride and astaxanthin contents of krill surimi with added SPI were 55.0 mg/kg and 0.8 mg/kg, respectively.

Monacolin K (MK) was produced on soybean using Monascus ruber GM011 by a two-stage-fermentation process. The optimal temperature was identified as $28^{\circ}C$. Higher yield was obtained by multiple-level-temperature cultivation than by single-level-temperature cultivation. The highest yield of total MK, 4.810 mg/g dry soybean product, was attained after 30 days of solid-state fermentation. No citrinin could be detected in the fermented soybean.

To reduce the content of undesirable erucic acid in mustard oil (MO), it was enzymatically modified with capric acid using immobilized lipase TL IM to produce structured lipid (SL). After reaction, the content of erucic acid was reduced up to 21.7% under the performed reactions in this study. Meanwhile, unsaturated fatty acids existing at sn-2 position (oleic acid, linoleic acid, and linolenic acid) in MO were not much changed.
