摘要: 選用湖北省推廣面積較大的茶樹品種鄂茶10號一芽四五葉為原料,對青磚茶關(guān)鍵工序-渥堆進行三因素(茶坯含水量、渥堆溫度和濕度)三水平的正交優(yōu)化試驗。結(jié)果表明,茶坯含水量和渥堆濕度對青磚茶品質(zhì)形成影響較大;最佳渥堆參數(shù)如下:茶坯含水量40%,發(fā)酵環(huán)境濕度70%,發(fā)酵環(huán)境溫度45 ℃。

關(guān)鍵詞:低氟青磚茶; 鄂茶10號; 渥堆; 品質(zhì); 工藝優(yōu)化

Abstract: One bud four five leaves of the tea tree variety E tea No. 10 popularized in Hubei Province were selected as the raw materials. An orthogonal optimization experiment was conducted on the key process of Qingzhuan tea, pile-fermentation, with three factors (tea dhool moisture content, temperature, and humidity) at three levels. The results showed that the moisture content of the tea dhool and the humidity of the pile-fermentation had great influence on the quality of Qingzhuan tea; the optimal parameters were as follows: Moisture content of the tea dhool(40%), humidity (70%) in the fermentation environment, and temperature (45 ℃) in the fermentation environment.

Key words: low-fluorine Qingzhuan tea; E tea No. 10; pile-fermentation; quality; process optimization
