Abstract

This study was conducted to investigate the major chemical components of dried broccoli (Brassica oleracea var. italica Plenck) sprouts. The proximate compositions of broccoli sprouts as dry matter basis were 2.04% of moisture content, 22.04% of crude protein, 12.80% of crude fat, 6.25% of crude ash, and 56.87% of carbohydrate, respectively. The major free sugars were identified as ribose, glucose and fructose. Analysing total amino acids, 15 kinds of components isolated from broccoli sprouts. The essential amino acid contained in broccoli sprouts accounted for 45.62% of total amino acid, while the non-essential amino acid accounted for 54.38%. Fatty acids were 3.19% of saturated fatty acids, 14.42% of monounsaturated fatty acids and 82.39% of polyunsaturated fatty acids. Cis-11,14-eicosatrienoic acid, linoleic acid and oleic acid were the major fatty acids among 14 fatty acids detected in dried broccoli sprouts. Lactic acid was the major organic acids. The contents of vitamin A and vitamin E were 0.06 mg% and 0.82 mg%, respectively. The mineral contents of dried broccoli sprouts were greater in order of Cu

브로콜리 싹의 생리활성 기능과 이용 가능성에 관한 연구의 일환으로 브로콜리 싹의 일반성분 및 영양성분을 측정한 결과는 다음과 같다. 일반성분은 건물(dry basis)을 기준으로 수분 함량은 2.04%, 조단백질 22.04%, 조지방 12.80%, 조회분 6.25% 및 탄수화물 56.87%를 함유하였다. 구성당은 ribose가 가장 많았고 다음으로 fructose, glucose 순으로 총 3종이 검출 되었다. 아미노산은 lysine 함량이 691.09 mg%로 가장 많이 함유되었고, 다음으로 leucine, aspartic acid, glutamic acid, arginine, phenylalanine, valine 순으로 검출 되었다. 브로콜리 싹의 구성 지방산 중 포화지방산 함량은 palmitic acid가 가장 높았으며 arachidic acid, lignoceric acid, behenic acid 순으로 나타났다. 불포화지방산은 cis-11,14-eicosatrienoic acid가 가장 높았으며 linolenic acid, linoleic acid, oleic acid 순으로 나타났다. 유기산은 총 3종의 유기산이 검출되었으며, 이 중 lactic acid가 가장 많았고, 다음으로 malic acid, citric acid 순으로 검출되었다. 비타민 A와 E의 함량은 각각 0.06 mg%와 0.82 mg%이었다. 무기질은 총 8종의 무기질 성분이 검출되었으며, 이 중 K 함량이 가장 많았으며, 다음으로 Mg, Na, Fe 순이었고 Zn, Mn, Cu의 함량은 미량이 었다. 이상의 결과 브로콜리 싹은 필수아미노산 및 필수지방산을 비롯한 항산화 비타민과 무기질을 다량 함유하고 있어 브로콜리 싹의 식품 재료로의 이용화가치가 한층 더 높아질 것으로 기대되어지며, 브로콜리 싹 분말을 이용한 다양한 조리법의 개발과 더불어 가공식품 및 기능성 식품으로의 제품 개발이 필요하다.
