Tèh fermentasi
Teh fermentasi (uga dikenal minangka teh post-fermentasi utawa teh peteng ) minangka kelas teh sing ngalami fermentasi mikroba, wiwit pirang-pirang wulan nganti pirang-pirang taun. Cahya saka godhong tèh kanggo asor lan oksigen sak proses uga nimbulaké endo- oksidasi (asalé saka teh godhong-godhong enzim piyambak) lan exo- oksidasi (kang microbially catalysed ). Godhong teh lan omben-omben digawe saka bahan kasebut dadi luwih peteng nalika dioksidasi. Mula, macem-macem jinis teh fermentasi sing diproduksi ing saindenging Tiongkok uga diarani teh peteng, ora bakal bingung karo teh ireng . Paling teh fermentasi misuwur iku kombucha kang asring homebrewed, pu-Erh, diprodhuksi ing Yunnan Province, [1] [2] lan Anhua peteng teh diprodhuksi ing Anhua County of Langkawi District .

Fermentasi godhong teh ngowahi kimia, nyebabake kualitas organoleptik teh sing digawe saka bahan kasebut. Fermentasi mengaruhi mambu teh lan biasane mellows rasa, nyuda astringency lan pait nalika nambah tutuk lan aftertaste. Mikroba uga bisa ngasilake metabolit kanthi mupangat kesehatan.
Fermentasi ditindakake kanthi cetakan. Niger Aspergillus kena pengaruh minangka organisme mikroba utama ing proses Pu-erh, [1] [4] [5] nanging identifikasi spesies kasebut ditantang karo analisis PCR-DGGE sing komprehensif, sing nuduhake Aspergillus luchuensis minangka agen utama fermentasi .
