Ammonia is one of the compounds released during the food spoilage process, so a device that can detect ammonia can be used as an indicator of food spoilage. This article reports on the preparation and characteristics of Starch/PVA composite films with Syzygium oleana as indicator films to detect ammonia vapor. The indicator was made by first preparing the starch / PVA composite films by casting method and then the films were dipped in Syzygium oleana extract. These films were characterized by using a UV-Vis spectrophotometer, Fourier Transformed Infra-Red Spectrophotometer and tested for mechanical properties such as tensile strength and elongation, and the water vapor transmission rate (WVT). The results showed that the addition of PVA reduced the absorbance value in the UV and visible area, the value of the water vapor transmission rate and the tensile strength but the elongation value of the film on the other hand rose. The indicator films can detect ammonia which was marked by its color change from red to blue. For further application, it can be used as a smart packaging label that can detect food freshness.

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.

κ-carrageenan/gelatin mixtures and canola oil can form an emulsion film when they are well combined and can mediate the release of volatile substances. The objectives of this study were: 1) to investigate the effect of different ratios of κ-carrageenan/gelatin with and without the addition of canola oil on moisture content, solubility, thickness, water vapor transmission rate, tensile strength and percent elongation, 2) to study the release of ethyl acetate with different ratios of κ-carrageenan/gelatin with added canola oil. Edible films were prepared with varying ratios of κ-carrageenan/gelatin with and without the addition of canola oil. Ethyl acetate release from selected films was also observed. The results showed that different ratios of κ-carrageenan/gelatin with canola oil addition induced changes in moisture content, thickness, water vapor transmission rate, and tensile strength (p<0.05). A significant decrease in the water vapor transmission rate of films was induced by canola oil with a ratio of κ-carrageenan/gelatin of 1.35:1.65. In addition, κ-carrageenan/gelatin at a ratio of 1.35:1.65 with added canola oil triggered a larger release of ethyl acetate. These findings confirmed that different ratios of κ-carrageenan/gelatin with canola oil could be used to tailor emulsified films with enhanced barrier properties and to trigger the release of volatile substances.

Red Bean

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. The results of the best treatment were 0.16 mm thickness, 4.87 MPa tensile strength, 18.02% elongation, 4.73 g / m2/ day WVTR, 45.14% solubility and 3.98 A / mm transparency.
