Abstract

Perkembangan permintaan konsumen akan zat warna mendorong berbagai industri menghasilkan varian zat pewarna. Hanya saja, informasi akan dampak penggunaan pewarna sintesis menekan penggunaan kembali pewarna natural. Antosianin menjadi salah satu zat warna alami yang layak untuk dimanfaatkan lebih lanjut, khususnya di bidang pangan. Kelopak Bunga Telang (Clitoria ternatea L.) adalah bahan yang telah diakui menjadi sumber penghasil zat warna antosianin secara alami. Ultrasound-Assisted Extraction dipromosikan sebagai prosedur ekstraksi terkini yang mampu mengatasi kelemahan metode ekstraksi konvensional. Penelitian ini telah berupaya mempelajari proses ekstraksi kelopak bunga telang hingga memperoleh ekstrak antosianin serta mengetahui faktor-faktor yang mempengaruhi proses ekstraksi dengan metode Ultrasound Assisted Extraction, hingga akhirnya dapat dimanfaatkan sebagai produk minuman. Dari penelitian ini diperoleh capaian optimum untuk ekstraksi zat warna dari kelopak bunga telang adalah pada kondisi F/S 0.02 g/ml, suhu ekstraksi 60°C, dan waktu ekstraksi 90 menit, dengan konsentrasi antosianin di dalam minuman yang didapatkan sebesar 19.57 mg/L.

Abstract

The potential source of lipid material is spent coffee grounds (SCG). However, simultaneously, polar co-compounds (e.g., caffeine, chlorogenic acid, and cafestol) can be leached using ethanol-based processing, which must be separated in stages. The article is a thermodynamic study on an equilibrium-based multistage coffee-oil separation flowsheet with ethanol solvent (treated as 96 %(w/w) ethanol in this study) and a dry-basis definition of the feed. The flowsheet was adjusted to represent a sequential mixer-separator with solids proceeding stage-to-stage and fresh solvent contacts, with the first and second stages intended to demonstrate the leaching process, and the rest performed the purification process. Stagewise results indicate that cumulative elimination of the three monitored polar compounds is over 97% at Stage 3 and over 99.9% at Stage 4, and there is a plateau in the impurity removal; additionally, Stage 5 provides only slight further elimination. At the fifth level, oil recovery drops beyond the 69% (S/F 1:1, 40 C) to 58 (S/F 5:1, 60 °C), where an equilibrium-based trade-off between separation ability and lipid retention is shown. Varying binary interaction parameters (BIP) by 10% values resulted in slight alterations of recovery and never affected the qualitative stagewise inferences. Since this work is only done with the simulations of equilibrium, all the performance values are to be understood as the thermodynamic tendencies and the upper-bound signal; engineering design is to be suggested with an explicit experiment and with the separation/solvent-recovery studies on the laboratory level.
