中文摘要: |
为了解产黄青霉在普洱茶渥堆发酵中的功能和安全性,利用普洱茶中分离、鉴定得到的产黄青
霉,接种于潮水量 35%的云南大叶种晒青毛茶,30益发酵 25d 制备得发酵样,进行感官、理化和安全性分析。 结
果表明:与对照样相比,发酵样香气甜浓、汤色棕红、滋味较醇和,茶多酚、可溶性糖、茶褐素、红度和黄度等变
化较为深刻,且桔青霉素和展青霉素均低于国内外限量。 说明产黄青霉适于普洱茶的渥堆发酵,且发酵样的安
全性高。 |
英文摘要: |
In order to understand the function and safety of Penicillium chrysogenum during the fermentation
process of Pu'er tea, P. chrysogenum, separated from the Pu'er tea, was inoculated on the sun-dried green tea with
35% water, for 25 days at 30℃, then the sensory, security, physical and chemical of fermented sample was evaluated.
The results showed that compared with CK, the contents of tea polyphenols, soluble sugar, theabrownins, redness and
brightness changed significantly in the fermented sample with sweet aroma, henna tang, velvety flavor, and the
contents of citrinin and patulin were lower than the limition of home and abroad. In conclusion, P. chrysogenum is
one of preponderant fungus during the fermentation process of Pu'er tea, and plays a very important role in the
formation of Pu'er tea quality with high safety. |
