Edible Film

Bahan makanan pada umumnya sangat sensitif dan mudah mengalami penurunan kualitas. Bahan pengemas dari plastic banyak digunakan dengan pertimbangan ekonomis dan memberikan perlindungan yang baik dalam pengawetan. Penggunaan material sintetis tersebut berdampak pada pencemaran lingkungan, sehingga dibutuhkan penelitian mengenai bahan pengemas yang dapat diuraikan. Alternative penggunaan kemasan yang dapat diuraikan adalah menggunakan edible film. Edible film didefinisikan sebagai lapisan yang dapat dimakan yang ditempatkan di atas atau di antara komponen makanan, dapat memberikan alternative bahan pengemas yang tidak berdampak pada pencemaran lingkungan karena menggunakan bahan yang dapat diperbaharui dan harganya murah. Kandungan glukomanan pada umbi porang memiliki kemampuan   membentuk lapisan film yang baik, biocompatibility yang baik, biodegradable  serta memiliki kemampuan membentuk gel. Oleh karena itu umbi porang dapat dijadikan sebagai bahan dasar pembuatan biopolimer atau biodegradable polimer.    Edible film Glukomanan dan plasticizer gliserol dengan penambahan kitosan dibuat dengan proses pemanasan pada suhu 50oC dan pengeringan pada suhu 60oC. hasil terbaik edible film biodegradable diperoleh pada konsentrasi gliserol 3 ml dan glukomanan 3 gram dan memiliki nilai ketebalan 0,59 mm, nilai ketahanan air 25,229% dan nilai kemampuan terdegradasi 100%. Hasil spektrum FTIR terhadap edible film menunjukkan tidak adanya perubahan bilangan gelombang dari spektrum glukomanan, kitosan dan gliserol dengan gugus fungsi O–H, N–H dan C=O. Hal ini menunjukkan bahwa edible film yang dihasilkan hanya berinteraksi secara fisik.

White sweet potato starch (Ipomea batatas L.) and avocado seed starch (Parsea americana Mill) derived from local plants have the potential to be developed as agricultural products. Starch is a hydrocolloid compound as a potential local resource to be utilized. Glycerol function as an anti-freezing which is hygroscopic. This study aims to determine the ratio of white sweet potato starch with avocado seed starch and the concentration of glycerol for making edible film. This study was an experiment using a completely randimized factorial design with 2 (two) main factor consisting of a comparison of white sweet potato starch and avocado seed with 3 levels: P1 = 35%:65%., P2=50%:50%., P3=65%:35% and glycerol concentration with 3 levels: G1=1%., G2=2%., G3=3%. The best result reasearch were content of 23.03% (tratment P1G1), solubility of 55.57% (treatment P3G2)., swelling test of 9.83% (treatment P2g3)., elongation of 8.18% (treatment P3G2)

Pre Treatment

Durian (Durio zibethinus) and cempedak (Artocarpus integer) peels waste are not used by the society. The research aim is to extract pectin from durian and cempedak peels and to formulate the pectin into edible films for food packaging. The research stages were first pre-treatment of durian and cempedak peels, pectin extraction, pectin drying, and  pectin application as edible films with concentration of 0%, 5%, and 15%. Based on this research it was concluded that pectin can be extracted from durian and cempedak peels with yield result of 27.97 % and 55.58 %, respectively. Edible film obtained has  similar characteristics between raw materials cempedak and durian peels. The higher concentration of cempedak peel  pectin increased the thickness, but decreased the tensile strength and elongation at a concentration of 15%. While in edible films from durian peel pectin, the higher concentration of pectin decreased the thickness of edible film on pectin concentration of 15%, lowered tensile strength and raised the edible film elongation.Keywords: waste, durian, cempedak, pectin extraction, edible film

Alginate from algal biomass is used as edible film and the incorporation of antimicrobial agents improves its performance to increase the shelf-life of fresh foods. However, environmental conditions and intrinsic properties of films influence their release. The aim of this study was to investigate the effect of the concentration and type of encapsulating agent and pH of emulsions on the physical and antimicrobial properties of alginate-carvacrol films. Films containing alginate, carvacrol as antimicrobial agent, and Tween 20 or trehalose (0.25 and 0.75% w/w) as encapsulating agents were obtained from suspensions at pH 4 and pH 8. Physical characterization of emulsions and films and antimicrobial properties (E. coliandB. cinerea) was evaluated. Results showed that droplets size depended on trehalose concentration, but emulsion stability depended on pH and type of encapsulating agent, being more stable samples with trehalose at pH 4. Although films with Tween 20 presented the highest opacity, they showed the best antimicrobial properties at initial time; however, during storage time, they lost their activity before samples with trehalose and relative humidity (RH) was the principal factor to influence their release. Therefore, sample formulated with 0.25% trehalose at pH 4 and stored at 75% RH had the best potential as edible film for fresh fruits.
