Abstract

This study was performed to investigate the effects of different cooking methods (boiling, roasting, stir-frying, and deep-frying) on folate retention in 6 kinds of mushrooms (Beech-, button-, Juda's ear-, oak-, oyster-, and winter-mushrooms) frequently consumed in Korea. In order to assure reliability of analytical data, trienzyme extraction-L casei method was verified and analytical quality control was also evaluated. Folate contents of mushrooms varied by 6.04-64.82 g/100 g depending on the type of mushrooms. and were significantly affected by cooking methods. Depending on cooking methods, folate contents of mushrooms decreased by 22-48%, 2-31%, and 17-56% for Juda's ear-, oak- and oyster-mushrooms, respectively, while 17-90% of folate was increased in Beech mushroom. Overall, the largest weight loss was found in boiled mushrooms, but the lowest one in deep-fried samples. True folate retention rates considering processing factor were less than 100% for all cooked mushrooms except for Beech samples. Overall, folate loss was the largest by boiling with water but the smallest by deep-frying. Both accuracy and precision of trienzyme extraction-L-casei method were excellent based on a recovery close to 100% and coefficient variations less than 3%. Quality control chart of folate analysis (n=26) obtained during the entire study and an international proficiency test (z-score=-0.5) showed that trienzyme extraction-L casei method is reliable enough for production of national folate database.

엽산은 체내에서 아미노산과 핵산의 합성에 필수적인 성분이며, 세포 분열과 성장에도 중요한 역할을 담당하며 유아기, 성장기, 임신기 및 수유기에 높게 요구되는 수용성 비타민이다. 버섯류는 다양한 영양 및 생리활성 성분의 존재가 알려지면서 국내 식단에서 차지하는 비중이 점차 높아지고 있으나 실제로 섭취하게 되는 조리된 버섯류의 엽산 성분에 관한 데이터베이스는 거의 전무한 실정이다. 본 연구는 4가지 표준조리법(삶기, 굽기, 볶기, 튀기기)에 따른 6종 버섯(백만송이버섯, 양송이버섯, 목이버섯, 표고버섯, 느타리버섯, 팽이버섯)의 엽산 함량 변화를 분석하고 조리 전 후의 중량 변화를 고려한 가공계수를 산출하였으며 이를 적용한 엽산 잔존율을 평가하였다. 또한, 분석 결과의 국가 영양성분 데이터베이스로의 활용을 위하여 엽산 분석에 사용된 trienzyme extraction-L casei 분석법을 검증하고 내 외부 분석품질관리를 수행하여 분석 결과의 신뢰도를 확보하였다. 생버섯 6종의 엽산 함량은 버섯의 종류에 따라 $6.04-64.82{\mu}g/100g$의 범위를 나타내었으며(느타리버섯 > 팽이버섯 > 표고버섯 > 양송이버섯 > 백만송이버섯 > 목이버섯) 이는 조리법의 종류에 따라 다양하게 변화되었다. 목이, 표고, 및 느타리버섯은 네 가지 모든 조리법에서 엽산 함량이 각각 22-48, 2-31, 17-56%로 감소된 반면, 백만송이 버섯은 모든 조리법에서 17-90% 증가되었다. 한편, 양송이 버섯과 팽이버섯의 경우, 삶기에서는 생버섯에 비하여 엽산 함량이 각각 16%와 34% 감소한 반면, 튀기기에서는 각각 24%와 465%의 증가를 나타냈다. 조리 전후의 버섯의 중량 차이는 조리수를 이용한 삶기에서 가장 적었으며 고온에서 조리되는 튀기기에서 가장 높게 나타났다. 이러한 조리법에 따른 무게 변화를 고려한 가공계수를 고려하여 엽산 잔존율을 계산한 결과, 백만송이버섯을 제외한 5종 버섯에서는 대부분의 조리법에서 100% 이하의 잔존율을 보였으며, 전체적으로 삶는 조리법에서 엽산 잔존율 감소가 크게 나타났으며 튀기는 조리법에서는 비교적 잔존율이 높게 유지되었다. Trienzyme extraction-L. casei 분석법을 검증한 결과 우수한 정확성과(회수율 100.4%) 정밀성(CV 3% 이하)을 확인할 수 있었다. 또한, 본 연구가 진행되는 전 기간 동안 품질관리시료를 분석한 결과가 QC chart 관리수준 범위($172.58-188.20{\mu}g/100g$) 이내에 들어가 모든 분석이 관리하에 진행되었음이 확인되었다. FAPAS PT 시험에서 trienzyme extraction-L. casei 분석법이 z-score=-0.5를 얻어 분석 숙련도의 우수성도 확인할 수 있었다. 이러한 분석법 검증 및 품질관리 결과는 본 연구에서 생산된 생버섯 및 조리 버섯의 엽산 분석 데이터의 신뢰도가 우수함을 보여주는 것으로써 이는 국가식품 데이터베이스 구축을 위해 활용될 수 있을 것으로 판단된다.
