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。

摘  要:
[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 p H 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 p H 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.
