【摘要】 以印尼海域刺麒麟菜(Eucheuma spinosum)为原料,分别采用烘箱法、高温灼烧法、凯式定氮法、索氏提取法对其水分、灰分、粗蛋白、粗脂肪含量进行测定,通过正交试验确定最佳提取工艺参数。结果表明,该刺麒麟菜中水分、灰分、粗蛋白、粗脂肪含量分别为12.93%,22.68%,4.19%和0.58%。最佳提取工艺参数由正交试验确定为:常温下,9%KOH处理5 h,90℃提取4 h。得到凝胶强度为59g/cm2,产率为47.6%的ι-卡拉胶产品。更多还原

【Abstract】 In order to provide plenty data for ι-carrageenan production,the chemical compositions of Eucheuma spinosum were analyzed and technological parameters for ι-carrageenan extraction from this alga were studied.By oven drying method,ignition,Kjeldahl method and Soxhlet extraction,the contents of water,ash,crude protein and crude fat in Eucheuma spinosum were determined to be 12.93%,22.68%,4.19%,and 0.58%,respectively.The optimal parameters were established by orthogonal design to be treated with 9% potassium hydroxide for 5 hours under room temperature and extracted for 4 hours at 90 ℃.The yield of extraction was 47.6% and the gel strength of ι-carrageenan product was 59 g/cm2.更多还原
