摘要:
为探究江蓠(Gracilaria japonica)琼脂生产过程中碱处理工艺对碱消耗量及琼脂质量的影响，采用模型拟合优化琼脂提取碱处理工艺参数，以降低碱消耗量；研究不同碱处理工艺条件下制备的江蓠琼脂性质，测定出胶率、碱消耗量和江蓠中吸收碱量，建立碱处理工艺对琼脂质量和碱消耗量影响的关系模型。运用模型优化得到3个最佳碱处理工艺参数，即碱质量分数、碱处理时间和碱处理温度分别为6%、3.0 h和87 ℃。在此最佳工艺条件下，每生产1.00 t琼脂碱消耗量为1.83 t，江蓠中残碱量为1.10 t。与现有琼脂工业生产工艺相比，本研究优化工艺的琼脂质量没有变化，但碱消耗量和江蓠中残碱量分别降低12.02%和15.38%。
Abstract:
The present study was designed to explore the effect of alkali treatment on alkali consumption and agar quality of Gracilaria japonica,and the mathematical model was established to optimize the alkali treatment conditions for reducing alkali consumption.By measuring the properties,gel yield,alkali consumption and alkali absorption from Gracilaria japonica under different alkali treatment conditions,the relationship between alkali treatment conditions and agar quality and alkali consumption were analyzed.By using the newly established model,the alkali treatment parameters including alkali concentration,treatment time and temperature were optimized to be 6%,3.0 h and 87 ℃,respectively.Under the optimized conditions,the alkali consumption and the residue alkali in the seaweed were 1.83 t and 1.10 t per 1.00 t agar production,respectively.The optimized alkali treatment process showed the agar quality identical to the currently used industrial process for producing agar;however,the consumption of alkali and the amount of residue alkali in G.japonica reduced by 12.02% and 15.38%,respectively.
