Abstract
Sweet potato (Ipomoea batatas L.) is a type of tubers which can found easily in Indonesia. Sweet potato peel contains as much as 4.34±2.09% of starch that can be utilized in the making of food product or further processed into packaging. Edible pouch is an alternative to plastic packaging which made by heat sealing edible film. The aims of this research are to determine the chemical characteristic of sweet potato peel starch. Moreover, the effect of gelatinization temperature was evaluated. While the effect of different types of plasticizer including sorbitol, glycerol, and sorbitol:glycerol 1:1 and concentration of 20%, 30%, and 40% was also determined. The result shows that gelatinization temperature of 75°C was preferred as it exhibit water vapour transmission rate of 0.69±0.02 g mm/m2 hour. While the tensile strength was 1.59±0.13 MPa. Incorporation of sorbitol 20% results in best tensile strength of 2.78±0.09 MPa. However, it has a low solubility, and moderate water vapour transmission rate. / Ubi jalar (Ipomoea batatas L.) adalah salah satu jenis umbi yang mudah ditemukan di Indonesia. Kulit ubi jalar mengandung pati sebanyak 4,34±2,09% yang dapat digunakan dalam pembuataan produk makanan atau diproses lebih lanjut untuk dijadikan kemasan makanan. Edible pouch adalah alternatif dari kemasan plastik yang dibuat dengan cara heat sealing edible film. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik kimia pati kulit ubi jalar. Efek dari suhu gelatinisasi dievaluasi. Sementara efek dari penggunaan berbagai plasticizer seperti sorbitol, gliserol, dan kombinasi sorbitol:gliserol 1:1 dengan konsentrasi 20, 30, dan 40% juga dievaluasi. Hasil dari penelitian ini menunjukan bahwa suhu gelatinisasi 75°C merupakan suhu yang terpilih dengan permeabilitas uap air 0,69±0,02 g mm/m2 hour. Sementara kuat tarik sebesar 1,59±0,13 MPa. Penambahan sorbitol 20% menghasilkan kuat Tarik terbaik yaitu 2,78±0,09 MPa. Namun, edible pouch yang dihasilkan memiliki solubilitas yang rendah dan permeabilitas uap air yang sedang dibandingkan dengan perlakuan lainnya.
