Teh telah digunakan sebagai minuman ringan sejak zaman dahulu dan memiliki manfaat kesehatan. Namun, dalam beberapa tahun terakhir, teh diketahui memiliki efek sebagai bahan untuk perawatan kulit. Ampas teh bermanfaat untuk kulit wajah seperti membuat kulit tampak lebih awet muda, mengandung antioksidan. Dapat meredakan kulit kemerahan dan iritasi karena mengandung flavonoid dan tanin sebagai obat anti radang yang meredakan iritasi kulit. Toner digunakan untuk menyeimbangkan pH kulit, menyegarkan kulit, dan mempersiapkannya untuk langkah perawatan selanjutnya, seperti mengoleskan serum atau pelembab. Tujuan dari penelitian ini adalah membuat suatu inovasi sediaan pembersih wajah (toner) dari ampas teh hitam. Ampas teh diperoleh dengan mengekstraksi daun teh hitam kering dengan metode maserasi. Pengeringan dilakukan dengan menggunakan sinar matahari. Ampas teh hitam tersebut didapat dari hasil limbah rumah tangga di daerah tegal. Uji stabilitas fisik dilakukan dengan metode uji cycling test. Sediaan disimpan pada suhu kira-kira 4 °C selama 24 jam dan kemudian pada suhu kira-kira 40 °C selama 24 jam. Tes ini dilakukan selama enam siklus, dan diamati perubahan fisik meliputi organoleptis seperti bentuk, warna, bau, pH dan kejernihan. Hasil dari penelitian ini bahwa ketiga formula tersebut masih dalam bentuk sediaan cair, pada pengujian warna mendapatkan hasil akhir bahwa formula pertama bening, formula kedua dan formula ketiga berwarna coklat kekuningan. Bau yang didapatkan yaitu bau khas, hasil akhir pengujian pH pada formula pertama yaitu 6, pada formula kedua dan formula ketiga yaitu 7. Pada uji kejernihan yaitu formula pertama jernih, formula kedua dan formula ketiga terdapat partikel, tetapi dari ketiga formula tersebut yang memenuhi standar yaitu formula yang pertama.

“…The content of bioactive compounds in tea is known to be the basis for the many benefits contained in tea. Bioactive components that are widely contained in tea are polyphenols which can be divided into two major groups, namely flavonoids and phenolic acids (Sudaryat et al, 2015). Polyphenol compounds are one type of compound that can provide hydroxyl atoms to free radicals.…”

Tea is one of the most popular refreshing drinks due to its strong and delicious flavor, it is also known to have many health benefits. Tea comes from the tops (shoots) of the leaves of the Camellia sinensis plant which are processed and then dried. Black tea is the most widely produced tea in Indonesia, which is about 78% of the total tea production. Black tea can be divided into two categories based on the process, namely orthodox and CTC black tea, which are known to contain many chemical compounds that are good for the body. The content of chemical compounds in tea is generally contained in its leaves which are classified into four major groups, namely phenol groups, non-phenol groups, aromatic compound groups, and enzymes. The content of chemical compounds present in tea will form the physical characteristics of tea, namely appearance, liquor, and infused leaf. Many research found that black tea could reducing the accumulation of dental plaque, preventing obesity, preventing cardiovascular disease, as an antibacterial and anticancer, and preventing osteoporosis. The compound epigallocatechin gallate which is the main component in tea has been shown to have insulin-potentiating activity. In addition, theaflavin compound in tea is also known to inhibit the entry of HIV-1 in the body.

This study aimed to investigate the impact of fermentation time and the best formulation of black tea and noni fruit juice on the production kombucha with the highest hedonic value and antioxidant activity. The research method involved (1) preparing kombucha tea, (2) assessing antioxidant activity, Total Solids value, pH value of the sample, and (3) conducting statical analysis using One-Way ANOVA followed by Tukey’s Post Hoc Test at a confidence level a = 5% and T test. The addition of noni juice was found to increase the antioxidant activity in kombucha; however, it reduced the overall hedonic value of kombucha. In conclusion, this study determined that sample P2 (200 mL of noni juice in 800 mL of black tea) was the best formulation. Statistical tests revealed that both fermentation time and formulation P2 significantly influenced the increase in antioxidant activity, reaching 41.20%. Additionally, the highest hedonic score was achived by the control sample fermented for 7 days, which scored to 6.68%.
