Edible films are thin layers made from hydrocolloids, lipids, and their combinations, functioning as a barrier to mass transfer. The hydrocolloid source that commonly used for the edible film is starch. Lesser yam has the potential to be developed into food packaging products. It has a high starch yield (21.4%). The starch properties, which usually obstruct the edible film production are not resistant to high temperature, it produces a starch suspension with viscosity and ability to form a gel is not uniform, cannot stand in acidic conditions, does not resist stirring, limited solubility in water, and starch gel is easy to syneresis and brittle. This study aimed to investigate the effect of glycerol and Aloe vera concentration on the physical and mechanical edible film. Randomized complete block design (RCBD) factorial with two factors was adopted. The first factor was Aloe vera concentration (0, 1%, 0.2% and 0.3% b / v), and the second factor wasglycerol concentration (17.5, 22.5 and 27.5% v/b). The parameters tested included thickness, tensile strength, elongation, solubility, transparency, and water vapor transmission rate (WVTR). The results showed an interaction between the addition of glycerol and Aloe vera to thickness, tensile strength, solubility, transparency, and WVTR. The best characteristics of edible film were produced by the addition of glycerol 17.5% and Aloe vera0.1% with the thickness (0.11 mm), tensile strength (2.03 MPa), elongation (15.38%), solubility (64.44%), transparency (2.88 mm-1), and WVTR (13.27 g m-2 24 h-1).

Red bean starch is a food ingredient that has a high starch content, which can be used as an edible film. Edible films from the starch group still have shortcomings, namely having brittle and stiff properties, so it is necessary to add other materials to improve the properties of the edible film , namely by adding okra gel. The addition of okra gel is expected to improve the physical and mechanical properties of the edible film. The purpose of this study was to determine the interaction with the addition of variations in the concentration of red bean starch and okra gel on the physical and mechanical characteristics of the edible film. This research consists of two research factors. The first factor is the concentration of red bean starch which consists of 3 levels, namely 4%; 5%; 6; (b / b). The second factor was the concentration of okra gel which consisted of 3 levels, namely 3%; 8%; 13% (w / v). The experiment used a factorial randomized block design (RBD). Observation parameters include analysis of thickness, transparency, tensile strength, elongation, water vapor transmission rate and solubility. The results of this study indicate that there is no interaction between the addition of red bean starch and okra gel on thickness, transparency, tensile strength, elongation, water vapor transmission rate and solubility edible film. The best treatment with results that were close to standard was edible film with a concentration of 5% (w / w) red bean starch and 3% (w / v) of okra gel concentration.

Plastics are widely used as packaging materials but can cause environmental problems because they are not easily degraded. Therefore, it was necessary to find alternative packaging materials that were easily degraded, including edible film. The main raw materials for edible film were alginate and plasticizers including glycerol and virgin coconut oil (VCO). The aims of this study were to determine the characteristics of edible films composed of alginate, glycerol and VCO and to determine the best concentration of alginate in edible films. The study was carried out through the manufacture of edible films composed of alginates at various concentrations (2, 3, 4, 5 and 6%), 10% glycerol and 0.01% VCO. The characteristics observed included thickness, tensile strength, elongation, solubility, and water vapor transmission rate (WVTR). The results showed that increasing the concentration of alginate increased the thickness, tensile strength, and elongation of edible films but reduced the solubility and WVTR of edible films. The best alginate concentration was 4% with the following characteristics: thickness, 0.12±0.01 mm; tensile strength, 1.59±0.12 MPa; elongation, 48.73±1.97%; solubility, 92.07±0.57%; and WVTR, 49.18±0.59 g/m2.24 hours. The various alginate concentrations significantly affected the thickness, tensile strength, elongation, and water vapor transmission rate of the edible film produced.

<p>The utilization of starch-base ingredients, such as sago starch for the manufacture of edible films, is still growing. The nature of the film produced from starch material is still not optimal, hence research is needed to improve its utilization. Starch composites with other ingredients, such as pectin, are expected to grow their properties. The study aimed to characterize the properties of edible film produced from molat sago starch-pectin composites, including thickness, tensile strength, elongation, solubility, transparency, and water vapor transmission rate. The study was conducted from July to August 2017 at Food Chemistry and Biochemistry Laboratory, Pattimura University, Ambon, and Food Engineering Laboratory, Gadjah Mada University, Yogyakarta. The design used was a non-factorial completely randomized design of the treatment of composite sago-pectin starch, with five levels of treatment (3: 0; 2.75:0.25; 2.5:0.5; 2.25:0.75 and 2:1 (g/g)). Based on the results of the analysis of diversity, the treatment of composite sago-pectin starch affects the changes in the mechanical, physical, and barrier characteristics of the edible film. Increasing the concentration of pectin (0-1%) in the film solution decreases the elongation of the film, but increases the properties of thickness, tensile strength, solubility, transparency, and the rate of water vapor transmission. The treatment of sago-pectin starch composites 2:1 can improve the physical and mechanical properties of edible films, although it has a high value of solubility and water vapor transmission rate.<em></em></p><p align="center"><strong>ABSTRAK</strong></p><p>Pemanfaatan bahan dasar pati-patian, seperti pati sagu untuk<em> </em>pembuatan<em> edible film</em> masih terus berkembang.

An evaluation of the physicochemical properties of plastic films made from chitosan, by modifying the order of the different treatment processes, namely: a) DPMA (deproteination, demineralization, deacetylation), b) DMKA (demineralization, decoloration, and deacetylation) has conducted. The results of scanning FT-IR of the product shows that chitosan has identical spectrum compare of standard compound. Chitosan product from tiger prawn shells was the used as raw material for the manufacture of bioplastics. Experiments variable on the manufacture of edible film is a study of the effect of the use of different plasticizers (glycerol and sorbitol) and carboxylmethylcelullose (CMC) additives to the physicochemical, mechanical characteristics, and edible film functional. The results showed that all the edible film produced has a clear coat with a thickness between 0.05 to 0.3 mm. Meanwhile, the film density is highest at the DPMA + chitosan edible film sorbitol + CMC with a value of 1.7300 g/cm3. The use of plasticizer sorbitol provides great tensile strength but not too elastic, compared to the glycerol, while an increase in the average CMC can increase tensile strength and %Elongation. The use of different plasticizers and additives CMC does not significantly affect its functional properties, where the value of WVTR (water vapor transmission rate) is relatively the same on both types of edible films, ranging from 3.2409 to 4.8858 g /hr.m2.

Edible film is a packaging that has the advantage of being easily degraded so that it does not cause environmental problems such as plastic waste which can pollute the environment. Edible film is considered to have good prospects for application in food ingredients, one of which is meat, because meat has a limited shelf life. The addition of antimicrobial ingredients to the edible film in the form of essential oil of basil leaves is useful for reducing microbial growth. The purpose of this study was to make edible films to extend the shelf life of frozen meat, utilize banana peels and durian seeds as the main ingredients for making edible films and use basil essential oil as an antimicrobial agent. The stages of activities carried out in this study included the preparation of raw materials for waste banana peels, durian seeds, and basil leaves. This stage includes the extraction process of each ingredient that produces pectin from banana peels, starch from durian seeds, and essential oil from basil leaves. Furthermore, the making of edible films from these raw materials varied the ratio between the mass of pectin and starch. The formed edible films were analyzed using FTIR, attractiveness test, and microbial growth testing by comparing meat coated with edible film and meat not coated with edible film. The characteristics of the edible film produced are 0.1 mm thick with a tensile strength value of 64.65 MPa - 75.34 MPa and a percent elongation value of 0.318% - 0.36%. The best edible film was produced at a ratio of 4: 1 (pectin: starch) with the addition of antimicrobials which had a film thickness of 0.1 mm with a tensile strength value of 75.34 MPa and 0.35% elongation percent.
