Abstract

In this research work, a biobag with goose (Oxalis tuberosa) starch for green tea (Camellia sinensis), which avoids the elimination of waste into the environment, was prepared and dissolved in hot water, suitable for immediate consumption and with a good physical appearance. The identification of the dosages was done with the ratio of starch and plasticizer (80:20), this ratio was given in 4 different treatments, 100 ml of water was placed as solvent, 0.04% of sunflower oil that helped the vapor transmission to decrease and 0.04% of emulsifier tween 60 that allowed the union of water and oil, avoided the presence of oil drops on the surface of the tea. For the statistical analysis, the sheets obtained from the applied treatments were evaluated, thus knowing the influence of each of the materials used, the lower percentage of glycerin which was 15% gave a sheet with a longer useful life by decreasing the humidity in its sheets, The percentage of vapor transmission was 0.00709 g⁄(h*m^2 ) , a lower amount because it contained sunflower oil that repels water vapor, the biodegradability of the films were in open and closed environments having a good disintegration when acting with water. It is concluded that the films obtained in Treatment 4 (TO4) disintegrated completely in hot water, with a percentage of 85:15 (starch: glycerin), with the use of the different materials the film had a longer useful life. It is recommended that this research work be improved with the use of other materials such as xylose crystals and other starches in the preparation of the films and be able to apply them to contain sugar, coffee, freeze-dried tea and chocolate for instant beverages.
