Brown granulated sugar clarify decoloring based on light calcium carbonate

就活化轻质碳酸钙对赤砂糖回溶糖浆澄清脱色效果进行研究,通过正交试验研究了活化轻质碳酸钙用量、反应温度、反应时间以及PAM用量等因素对赤砂糖回溶糖浆澄清脱色效果的影响,确定了澄清脱色的最佳工艺条件,研究表明:当活化轻质碳酸钙用量与赤砂糖回溶糖浆(锤度15%)质量比为0.5:100、反应时间32 min、反应温度75℃、PAM用量3 mg/kg时,脱色率可达56.8%。

In this paper, the mixed brown sugar juice was decoloured by light calcium carbonate. The effects of light calcium carbonate dosage, reaction temperature, reaction time and PAM dosage were discussed, and the optimum conditions were obtained as the following： the mass ratio of light calcium carbonate and remelt syrup of brown granulated sugar （mass fraction 15%） is 0,5：100, reaction time 32 min, temperature 75 ℃ and PAM dosage 3 mg/kg. The largest decolouring rate is 56.8%.
