Pengaruh waktu ekstraksi menggunakan ultrasonic assisted extraction terhadap antosianin jantung pisang (Musa spp)

Banana blossom is a source of anthocyanin that potentially utilized as natural dyes in the food industry. Anthocyanin from banana can be extracted using Ultrasonic Assisted Extraction (UAE) and maceration method. ultrasonic causes cavitation effect thereby provide an efficiency extraction time if compared with This study aimed to determine duration sonication treatment on total extract. Experimental design applied this research randomized block five treatments: for 24 hours, sonication: 5 minutes, 10 15 minutes 20 minutes. Sonication was carried out at 40 kHz. Parameters determined were content, color (L*, a*, b*), morphological structure soluble solid. The results showed did not significantly affect Total extract ranged 86.32 mg/L 87.31 mg/L. selected UAE sonication. resulted concentration mg/L, which has comparable hours parameter b*) solid 28.67, 12.54, 17.92 8.32 %Brix, respectively. Meanwhile, formation pores surface cells.
