| Summary: | <p><em>Edible film based on beeswax and carrageenan has been made using two types of plasticizers namely glycerol and sugar. Glycerol at a fixed concentration of 1% was combined with sugar (fructose, glucose and sucrose) each at three concentration levels of 0.5%, 1% and 1.5% w /v<sub>t</sub>. Edible film has water content, thickness, tensile strength, elongation and vapor transmission rate respectively 13.69-14.91%, 0.059-0.102 mm, 12.62-32.40 MPa, 13.34-43.57% and 17.65-25.38 g/m2/24 hours. The enhancement in plasticizer concentration resulted increasement of moisture content, thickness, elongation and water vapor transmission rate but decreased its tensile strength. All edible films showed lightness in range 84.45-85.61. Edible films with glycerol-sucrose plasticizer showed the lowest lightness. The scanning electron microscopy results indicated that edible films treated with plasticizer glycerol-fructose and glycerol-glucose have more homogeneous and smoother surface than edible control films and edible films with a glycero</em><em>l</em><em>-sucrose plasticizer.</em><em></em></p><p><strong><em>Keywords</em></strong><em>: edible film, fructose, glucose, plasticizer, sucrose </em></p><p><em><br /></em></p><p><strong>ABSTRAK</strong><em></em></p><p><em>Edible film</em><em> </em><em>(lembaran tipis dapat dimakan) berbasis karagenan-lilin lebah telah dibuat dengan menggunakan dua jenis plasticizer</em><em> </em><em>(bahan pemlastis) yaitu gliserol dan gula. Gliserol pada konsentrasi tetap 1% dikombinasikan dengan gula (fruktosa, glukos</em><em>a</em><em> dan sukrosa) masing-masing pada tiga level konsentrasi yaitu 0,5%, 1% dan 1,5% b/v<sub>t</sub>. Edible film mempunyai kadar air, ketebalan, kuat tarik, elongasi dan kecepatan transmisi uap air masing-masing sebesar </em><em>13,69-14,91%, 0,059</em><em>-</em><em>0,102 mm, 12,62</em><em>-</em><em>32,40 MPa, 13,34</em><em>-</em><em>43,57% dan 17,65</em><em>-</em><em>25,38 g/m<sup>2</sup>/24 jam. Kenaikan konsentrasi plasticizer menghasilkan kenaikan kadar air, ketebalan, elongasi dan kecepatan transmisi uap air namun menurunkan kuat tariknya. Semua edible film menunjukkan sifat warna yang baik dengan lightness antara 84,45-85,61 sedangkan edible film dengan plasticizer gliserol-sukrosa memperlihatkan lightness paling rendah. Hasil scanning electron microscopy menunjukkan bahwa edible film yang diberi perlakuan Plasticizer gliserol-fruktosa dan gliserol-glukosa memiliki permukaan yang lebih homogen dan halus daripada edible film kontrol dan edible film dengan plasticizer gliserol-sukrosa.</em><em> </em></p><p><em><strong><em>Kata kunci</em></strong><em>: edible film, fruktosa, glukosa, plasticizer, sukrosa</em><br /></em></p> |
