Quality Improvement Of Galbijjim Using Superheated Steam And High Hydrostatic Pressure

(과열증기와 높은정수압을 이용한 갈비찜의 품질향상)

​본 연구는 갈비찜 제품의 품질을 개선하고자 SHS와 HPP 기술을 적용한 시료를 냉장온도(5, 10°C)에서 저장하면서 그 품질 변화를 살펴보았다. 기호도 조사를 통해 SHS 조리가 일반 조리에 비해 높은 기호도를 보였으며 특히 다즙성과 조직감(연한 정도)이 향상되는 것을 알 수 있었다.
이것은 조직감 측정 결과와 같은 경향으로 SHS 조리가 일반 조리에 비해 조직이 연해져 부드러운 조직감을 부여하는 것을 알 수 있었다. 또한 지방의 산화반응을 억제하며 총균수의 증가폭도 일반 조리구에 비해 적은 것을 확인할 수 있었으며 SHS-HHP 병행 처리 시 5°C에서 15일간 저장하여도 검출 한계 수준(<1 Log CFU/G)으로 검출되었다. 또한 지방 산패도 값인 TBA 또한 SHS-HHP병행 처리군이 일반 조리에 비해 낮은 값을 보여 안전성을 확보할 수 있을 것으로 사료된다.
식육의 신선도를 나타내는 VBN은 간장 양념으로 인해 높은 값을 보였지만 육제품의 특성상 VBN 함량만으로 신선도 정도를 판단하기는 어려울 것으로 사료된다. 이상의 결과로 기존의 갈비찜 제품에 SHS 기술과 HPP 기술의 적용으로 제품의 품질 향상을 통한 기호도 상승과 유통기간 연장효과를 어느 정도 기대할 수 있는 것으로 생각되었다.

​This Study Investigated The Effects Of Superheated Steam (SHS) And High Hydrostatic Pressure (HHP) On The Quality Of Galbijjim. SHS Cooking Increased Moisture And Crude Fat Contents And Decreased Crude Protein Contents (P<0.05). The Value Of L Was Significantly Higher Upon SHS Cooking Compared To Conventional Cooking (CC), Whereas A And B Values Were Not Significantly Different Among The Samples. Hardness Decreased More Upon CC Than SHS. The Results Of The Safety Storage Experiment At Refrigeration Temperature Showed That The Total Number Of Bacteria Was Lower In SHS-HHP Than In CC-HHP. The Thiobarbituric Acid Value Increased To 0.70～1.56 Mg Malonaldehyde (MA)/Kg In CC-HHP After 15 Days, And SHS-HHP Showed 0.69 (0 Day)～1.24 (15 Days, 10°C) Mg MA/Kg. Volatile Basic Nitrogen Value Was 18.07～36.76 Mg% In CC-HHP, And That In SHS-HHP Also Increased To 17.06 (0 Day)～35.76 Mg% (15 Days, 10°C). Overall, SHS Cooking And HHP Reduced Microorganisms, Which Could Improve Product Quality And Sanitation.
