摘要:
The present invention relates to a method for extracting fucoxanthin and fucoidan from seaweed. The method of the present invention comprises: a first step of pulverizing seaweed; a second step of wrapping the pulverized seaweed in a non-woven fabric; a third step of inserting ethanol into the seaweed to perform room-temperature extraction; a fourth step of extracting the extract from the third step at a temperature of 50 to 60°;C; a fifth step of extracting fucoxanthin from a filtered solution in the extract from the fourth step; and a sixth step of extracting fucoidan from the residual seaweed in the extract from the fourth step. [Reference numerals] (A1) Fucoxanthin extracting·;purifying; (A2) Fucoidan extracting·;purifying; (BB) Pulverize dried seaweed; (CC) Wrap in a non-woven fabric; (D1) Insert ethanol; (D2) First room-temperature extraction (stirring or immersing); (EE,HH) Extract at 50°;C-60°;C; (FF,II,RR,TT) Filter; (G1) Put new seaweed into filtrate; (G2) Secondary room-temperature extraction (stirring or immersing); (JJ) Fucoxanthin extract; (KK) Ethanol vacuum-evaporation; (LL) Mix with excipient; (MM) Freeze-dry; (NN) Fucoxanthin powder; (OO) Residual seaweed; (PP) Insert water and organic acid; (QQ) First extracting at 90-100°;C; (SS) Insert water, Second extracting at 100~110°;C; (UU) Filtrate; (VV) Add CaCl_2; (WW) Remove alginic acid; (XX) Ultrafiltrating; (YY) Vacuum concentrating; (ZZ) Fucoidan liquid본 발명은 미역에서 후코산틴과 후코이단을 추출하는 방법에 관한 것으로, 그 구성은, 미역을 분쇄시키는 제 1단계와, 상기 분쇄된 미역을 부직포에 포장하는 제 2단계와, 상기 미역에 에탄올을 투입하여 상온추출하는 제 3단계와, 상기 제 3단계의 추출물을 50℃ 내지 60℃의 온도에서 추출하는 제 4단계와, 상기 제 4단계의 추출물 중 여과 용액에서 후코산틴을 추출하는 제 5단계와, 상기 제 4단계의 추출물 중 미역잔유물에서 후코이단을 추출하는 제 6단계를 포함하여 구성되는 것을 특징으로 한다.
