Pemanfaatan Teknik Ko-Kristalisasi Untuk Produksi Serbuk Ekstrak Sirsak

Lukman Junaidi, Enny Hawani Loebis, Rizal Alamsyah


Research on application of co-crystallization technique on production of soursop extract powder conducted to diversify soursop product that could be used as industrial commodity. Treatment on this research was influence of: (1) anti-caking magnesium oxide (MO), magnesium carbonate (MC), and magnesium silicate (MS), and (2) storage period (0, 1, 2, and 3 months), on the characteristics of soursop powder quality. The results showed co-crystallization could be applied to produce soursop powder that met the requirements of SNI 01-4320-1996. Based on its quality characteristics, soursop powder oursop powder MC resulted a better quality compared to s MO and s MS. MC had a quality characteristics: oursop powder Soursop powder water content 1.89%, pH 4.17, sugar content 83.75%, vitamin C 42.7  total soluble solids 98.1%, TPC mg/100g, 55 colonies/g, soursop powder until coliform < 3 MPN, and contain no mold and yeast. Storage of 3 months increased water content, pH, and TPC, and contrarily decreased sugar content, vitamin C  total soluble solids.  Based on the quality characteristics, soursop powder that , and was stored for 3 months still met the SNI 01-4320-1996 requirements.


Penelitian pemanfaatan teknik ko-kristalisasi untuk produksi serbuk ekstrak sirsak dilakukan untuk diversifikasi produk olahan buah sirsak yang dapat dijadikan komoditas industri. Perlakuan yang diamati meliputi pengaruh: (1) penggunaan jenis anti-kempal magnesium oksida (MO), magnesium karbonat (MC), dan magnesium silikat (MS) dan (2) masa simpan (0, 1, 2, dan 3 bulan) terhadap karakteristik mutu serbuk sirsak. Hasil penelitian menunjuk-kan bahwa teknik ko-kristalisasi dapat dimanfaatkan untuk menghasilkan serbuk sirsak yang memenuhi persyaratan mutu SNI 01-4320-1996. Berdasarkan karakteristik mutunya, serbuk sirsak MC memberikan hasil yang lebih baik dibandingkan dengan serbuk sirsak MS dan serbuk sirsak MO.  Serbuk sirsak MC memiliki karakteristik mutu: kadar air 1,89%, pH 4,17, kadar gula 83,75%, Vitamin C 42,7 mg/100g, total padatan terlarut 98,1%, ALT 55 koloni/g, koliform < 3 APM, dan tidak mengandung kapang dan khamir.  Penyimpanan serbuk sirsak sampai dengan 3 bulan mengakibatkan terjadinya peningkatan kadar air, pH, dan ALT, dan sebaliknya mengakibatkan penurunan kadar gula, vitamin C dan total padatan terlarut.  Berdasarkan karakteristik mutunya, serbuk sirsak yang disimpan selama 3 bulan tetap memenuhi persyaratan mutu SNI 01-4320-1996.
