摘要
[目的]为鱿鱼墨在饲料、保健品等领域的应用提供理论依据。采用高速离心法精制的鱿鱼墨黑色素与Ca^(2+)作用,探究酸度、温度、时间、黑色素添加量、Ca^(2+)浓度及盐度等因素对鱿鱼墨黑色素吸附Ca^(2+)的影响。[结果]当pH为4、温度为40℃、黑色素添加量为0.02g、吸附时间为10h时,鱿鱼墨黑色素对钙的吸附量最大,达到65%。不同浓度的氯化钠和氯化镁对黑色素吸附Ca^(2+)的影响较小,氯化铁对黑色素吸附钙的影响很大,随着氯化铁浓度的增大,吸附量急剧增加。[结论]鱿鱼墨黑色素对Ca^(2+)的吸附能力并不理想,吸附量也不多。
[ Objective ] To provide theoretical foundation for the application of squid melanin in feed, health care products and other fields. [ Method ] After high-speed centrifugation, squid melanin was used to absorb Ca2 ＋. Factors affecting the Ca2 ＋ absorption by squid melanin were re- searched, such as pH value ,temperature, time, salinity, squid melanin quantity and Ca2＋ concentration. [ Result] Absorption rate of squid melanin to Caz~ was the maximum （65%） under the conditions of pH 4,40 ~ temperature,0.02 g melanin dosage,and 10 h absorption time. Different concentrations of sodium chloride and magnesium chloride had relatively small effects on Ca2 ＋ absorption by squid melanin, bat ferric chloride showed great impacts. With the increase of ferric chloride concentration, the adsorbing capacity enhanced sharply. [ Conclusion ] Adsorption capac- ity of squid melanin to Ca〉 is not ideal.
