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Ca2+作用,探究酸度、温度、时间、黑色素添加量、Ca2+浓度及盐度等因素对鱿鱼墨黑色素吸附Ca2+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10 h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Ca2+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Ca2+的吸附能力并不理想,吸附量也不多.
Abstract
[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 researched, such as pH value, temperature, time ,salinity, squid melanin quantity and Ca2+ concentration.[Result] Absorption rate of squid melanin to Ca2+ 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, but ferric chloride showed great impacts.With the increase of ferric chloride concentration,the adsorbing capacity enhanced sharply.[Conclusion] Adsorption capacity of squid melanin to Ca2+ is not ideal.
