  • 본 리뷰 논문은 식품 산업에서 나노 기술의 활용에 관한 보고이다. 식품 병원균에 대한 항균 활성을 갖는 생리활성 성분은 식품 보존시 효율성을 향상시키고 보존성을 증진시키기 위해 나노입자(NPs)로 캡슐화된다. 그러나, 이러한 NPs는 인간에게 생체 적합성과 무독성을 지녀야 된다. 식품 보존분야의 발전은 일부 산업 분야에서 식품 포장용 NPs의 개발을 가져왔다. 식품 산업 분야에서 가장 일반적으로 사용되는 NPs 그룹은 금속 산화물이다. 산화 아연과 이산화 티타늄 같은 금속 산화물 NPs는 식품 재료에서 항균 활성을 나타내기 때문에, NPs는 강화된 기능적 특성으로 식품 보존에 사용될 수 있다. 식품 영양과 관능적 특성과 관련된 나노 기술의 적용은 나노 기반 식품 제조 및 보존에 관한 안전규제를 중심으로 간략하게 정리하였다.

  • In this paper a software program is given for food product life (shelf life) estimation. There are many modules of related operations, considering the characteristic of food industry so that users can easily use and understand the software, and we make the related data referenced In data base. In food industry acceleration tests depend on food deterioration differential equations. Based on such equations, etc, this paper suggests a shelf life estimation software program.

  • We investigated microbial and quality changes in wrap-packaged dry-aged beef after completion of aging and subsequent storage in a refrigerator. After 28 days of dry aging (temperature, $4^{\circ}C$; RH, approximately 75%; air flow velocity, 2.5 m/s), sirloins were trimmed, wrap-packaged, and stored at $4^{\circ}C$ for 7 days. Analyses of microbial growth, pH, volatile basic nitrogen (VBN), 2-thiobarbituric acid-reactive substance (TABRS), and instrumental color, myoglobin, and sensory evaluation were conducted on days 0, 3, 5, and 7. The results show that the number of total aerobic bacteria (TAB), yeast, and lactic acid bacteria increased with an increase in storage days, whereas no change in the growth of mold was observed during 7 days of storage. Based on the legal standard for TAB count, the estimated shelf-life of wrap-packaged dry-aged beef was predicted to be less than 12.2 days. However, the shelflife should be less than 6.3 days, considering the result of sensory quality (odor, taste, and overall acceptance). No significant change in visible appearance was also observed during 7 days of storage. The results suggest that the present quality indicators for meat spoilage (pH, VBN, and TBARS) should be re-considered for dry-aged beef, as its characteristics are different from those of fresh and/or wet-aged beef.

  • The aim of this study was to estimate the shelf life of butter and cheese products, with shelf life being a guide used to determine the storage period of food before deterioration. Butter and cheese samples stored at $10^{\circ}C$ and $15^{\circ}C$ had a shelf life of 221 d, while those stored at $25^{\circ}C$ and $35^{\circ}C$ had a shelf life of 109 d. Quality changes, including total cell count, coliform counts, Listeria monocytogenes counts, acid value, moisture content, pH, acidity and overall sensory evaluation, were monitored. In order to pass the overall sensory evaluation, a quality score of 5 points on a 9-point scale was required. For other quality criteria, legal quality limits were established based on the "Process Criteria and Ingredient Standard of Livestock Products" by the Animal, Plant and Fisheries Quarantine and Inspection Agency (Republic of Korea). The nonlegal quality limit was estimated by regression analysis between non-quality criteria (y) and overall sensory evaluation (x). The shelf life was estimated based on the number of days that the product passed the quality limit of the quality criteria. The shelf life of samples stored at $10^{\circ}C$, $15^{\circ}C$, $25^{\circ}C$ and $35^{\circ}C$ was 21.94, 17.18, 6.10 and 0.58 mon, respectively, for butter and 10.81, 9.47, 4.64 and 0.20 mon, respectively, for cheese.

심리적 식생활 만족도에 미치는 식습관 관련 변인연구 : 학부모 대상의 MSG 사용에 따른 편식행동감소 매개효과 (Influence of eating habits on psychological satisfaction with Food: A mediation effect of unbalanced eating habit among parents)

  • 본 연구는 초중고 자녀를 둔 학부모를 대상으로 식생활 만족도에 MSG 사용, 균형 잡힌 식습관, 주관적 행복감이 미치는 영향을 확인하고 MSG 사용과 식생활 만족도 간의 관계에서 편식행동 감소에 대한 생각이 매개효과를 가지는지 확인해 보았다. 이를 위해 수도권 내 학부모 800명을 대상으로 수집된 자료를 분석하여 회귀분석을 실시하였고 부트스트랩 분석으로 매개효과를 살펴보았다. 연구 결과, MSG를 사용하는 집단이 미사용 집단에 비해 식생활 만족도가 높은 것으로 나타났으며 주관적 행복감이 높고 균형 있는 식습관을 가질수록 식생활 만족도가 높은 것으로 나타났다. 또한, MSG 사용이 식생활 만족도를 높이는데 있어 편식행동 감소가 부분 매개효과를 가지는 것으로 나타났다. 이러한 결과는 식생활 만족도 향상에 MSG 사용이 긍정적 효과를 보이며 이는 편식행동 감소에 따른 것을 시사한다.
