Tepung yang tidak diozon memiliki keterbatasan untuk diaplikasikan pada produk pangan seperti swelling volume yang rendah dan tidak stabil pada kondisi tertentu. Modifikasi oksidasi menggunakan ozon sebagai salah satu oksidator kuat pada tepung hanjeli dapat meningkatan swelling volume tepung hanjeli yang tidak diozon. Tujuan dari penelitian ini adalah untuk menetapkan nilai swelling volume tepung hanjeli ozonasi agar dapat sesuai dengan produk yang akan dibuat serta memperluas pemanfaatan tepung hanjeli baik di kalangan industri pangan maupun masyarakat umum. Metode penelitian menggunakan Rancangan Acak Kelompok (RAK). Hasil penelitian menunjukkan proses ozonasi menggunakan flowrate 2 L/min selama 20 menit memiliki swelling volume lebih tinggi dibandingkan perlakuan lainnya dan juga hampir sama dengan swelling volume tepung terigu. Berdasarkan hasil penelitian, tepung hanjeli hasil ozonasi ini cocok untuk produk yang harus mengembang seperti kue, roti, brownies, dan lainnya.","PeriodicalId":31584,"journal":{"name":"PFTJ Pasundan Food Technology Journal","volume":"178 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79984406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
