연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

문제 정의

  • bulgaricus 복합 균주를 접종하면, 효소에 의해 생성된 저분자 당에 의해 두 유산균의 성장이 촉진되어 항산화 효과도 더 좋아지고 영양성분을 비롯한 이화학적 성분도 높아질 것으로 기대되었다. 따라서 본 연구에서는 효소와 복합 유산균으로 전처리한 밀싹분말의 이화학적 성분 및 항산화 활성을 분석하여 밀싹의 식품소재 활용성 증대를 위한 기초자료로 활용하고자 하였다.

핵심어 질문 논문에서 추출한 답변
밀싹의 효능은 무엇인가? 밀싹은 영양성분 뿐만 아니라 생리기능도 높은데, Kim HJ(2016)의 연구에 의하면 품종마다 약간의 차이는 있지만 밀싹이 밀종자보다 조단백질은 1~2% 정도, 조지방은 1% 정도, 페놀화합물은 4~10배 이상 많으며, ABTS radiacl 소거능은 3배 이상, 아질산염 소거능은 2배 이상 높아졌을 뿐 아니라 lipase 저해활성, α-glucosidase 저해활성, 항균활성도 더 높았다고 보고하였다. 밀싹은 간조직의 지질 축적 억제(Nepali S 2017), 궤양성 대장염 치료(Ben-Arye 등 2009), 혈당 강하(Lee 등 2009), 항산화 및 항염증 효과(You & Pyo 2015), MMP-1의 유전자 발현 억제 및 미백 개선(You & Moon 2016), 인체 모유두세포와 섬유아세포의 증식과 모발 성장 증진(Park SA 2017), 주름 개선(Kang SH 2019) 등의 효과가 있는 것으로 보고되었다. 이러한 기능성 소재 밀싹을 식품에 활용하고자 국내에서는 밀싹을 첨가한 머핀(Park LY 2015), 쿠키(An SH 2015), 스펀지 케이크(Lee BK 2015), 생면(Lee JS 2016), 설기떡(An SL 2018), 식빵(Joo 등 2018) 등 관련 연구가 증가하고 있다.
효소처리는 무엇인가? 효소처리는 동물, 식물, 미생물에서 기원한 효소를 농축, 추출, 정제 발효 등을 통하여 특정 부분만 가수분해하여 구조를 전환시켜 특이성분을 생산하고, 유효성분의 추출 수율을 높이는 방법이다(Yang 등 2006). 식물을 식품 제조 공정에 활용하려면 이들의 주요 성분인 셀룰로오스, 헤미셀룰로오스와 같은 고분자 화합물 등을 저분자로 전환하기 위한 가수분해 과정이 필요하다.
고분자 화합물 등을 저분자로 전환하기 위한 가수분해 과정에서 물리적, 화학적 방법의 분해에 비해 효소 분해가 가지는 장점은 무엇인가? 물리적, 화학적 방법을 통한 가수분해 과정은 분해 생성물 및 부산물이 많아 환경오염의 우려가 있으며, 에너지 소모 및 시설비가 크다는 단점이 있다. 이에 비해 효소 분해는 효소가 특정 기질에만 작용하여 부산물이 적어 환경오염이 적고, 반응되지 않은 물질은 다른 용도로 사용할 수 있으며, 시설비가 적게 드는 등의 장점이 있다(Park 등 1998; Kim JH 2009; Park SY 2012; Im 등 2016). 또한 효소처리를 한 원재료의 항산화(Kim 등 2008), 면역증진(Park 등 2015), 콜레스테롤 저하(Chai 등 2003) 등 생리활성이 증진되었다.
