Preparation method of selenium-rich ceramic teapot capable of enhancing aroma of tea water
The invention belongs to the field of new domestic functional ceramic materials, and particularly relates to a preparation method of a selenium-rich ceramic teapot capable of enhancing aroma of tea water, which comprises the following steps: uniformly mixing selenium-rich pottery clay and a pore-forming agent according to mass percent, adding water, mixing to prepare ceramic pug, aging, and preparing a green body of the ceramic teapot from the ceramic pug; drying and calcining the ceramic teapot green body to obtain a porous ceramic teapot blank; and coating the outer surface of the porous ceramic teapot blank with a layer of ceramic glaze, and then performing secondary firing to obtain the ceramic teapot. Filling the ceramic teapot with a dilute acid solution, and activating the ceramic surface at a certain temperature; filling the ceramic teapot with a cross-linking agent solution, and then filling the dried ceramic teapot with the prepared enzyme solution for adsorption; the ceramic teapot after adsorption is completed is filled with a dopamine Tris-HCl buffer solution, and soaking is performed to strengthen the immobilization effect. The enzyme is immobilized in the ceramic teapot by adopting an enzyme immobilization technology, and the prepared ceramic teapot has a tea aroma enhancement effect.
本发明属于日用功能陶瓷新材料领域，具体涉及一种能够使茶水增香的富硒陶瓷茶壶的制备方法，按质量百分数计，取富硒陶土和造孔剂混合均匀，再加入水，混练制成陶瓷泥料并进行陈腐，采用陶瓷泥料制备陶瓷茶壶生坯；将陶瓷茶壶生坯干燥后煅烧得到多孔陶瓷茶壶胎体；将多孔陶瓷茶壶胎体的外表面涂覆一层陶瓷釉后进行二次烧成，得到陶瓷茶壶；采用稀酸溶液注满陶瓷茶壶在一定温度下活化陶瓷表面；先用交联剂溶液注满步骤陶瓷茶壶后向干燥后的陶瓷茶壶中注满配制的酶液进行吸附；向吸附完成后的陶瓷茶壶中注满多巴胺Tris‑HCl缓冲液，浸泡以强化固定化效果。本发明通过采用固定化酶技术将酶固定在陶瓷茶壶中，制得的陶瓷茶壶具有茶水增香效果。
