摘要 为进一步利用虾壳资源,以克氏原螯虾虾壳为原料,采用乙酸提取法从虾壳中进行乙酸钙的提取,探讨了乙酸浓度、液料比、温度和时间4个因素对虾壳钙提取的影响,在此基础上利用响应面法研究各自变量及其交互作用对虾壳中钙提取率的影响。结果表明,影响钙提取率的因素大小顺序为:液料比>温度>乙酸的浓度>酸解时间。乙酸钙提取最优条件是乙酸浓度73.60 g/L,反应时间3 h,反应温度65℃,液料比11.60∶1(m L/g),在此条件下,得到克氏原螯虾虾壳中钙的得率为20.45%。此工艺下钙的得率较高,成本较低。本研究为以虾壳为钙源进行乙酸钙生产提供了技术参考。 In this paper, for further application of clarkia shell resource, the calcium was extracted from procambarus clarkia by acetic acid inquiring the four factors such as extraction temperature, acid concentration, the reaction time, liquid to solid into the extraction yield of calcium acetate.Based on the single factor experiments, the influence of the variables and their interaction on the impact on the extraction yield of calcium acetate was studied by response surface methodology.The results showed that the effect order of the factors on the extraction yield of calcium acetate from shrimp shell was:liquid to solid, temperature, concentration of acetic acid, and the time.The optimum extraction conditions were as follows:acid concentration 73.60 g/L, the reaction time 3 h, extraction temperature 65 ℃ ,liquid to solid 11.60:1 (mL/g)and the most calcium extraction rate was 20.45%.The present method gives an acceptable yield and improved quality of calcium acetate.And this study could be helpful for the production or manufacture of calcium acetate based on shrimp shell as calcium resources.
