Study On The Formational Techniques Of Starch Edible Tableware

Protecting environment and using resources have become important signs of modern social progress and civilization. This paper discusses the formational technique and capability of starch edible tableware for protecting environment, controlling 'white pollution'. Under the condition of primary material is edible, through the preliminary experiment decided the central factor and range of factor. This experiment is practiced according to 3 performance standards used in GB18006.1—1999 General Specification for Single Use and Degradable Lunch Container and Drinking Set . Through orthogonal test , the most optimized technical parameters can be find. Influence of plasticizers,waterproof and intensifier on using performance of tableware was studied when the condition of the most optimized technical parameters is applied.Through attenuated total internal reflectance analysis, the molecule can be find which influence using performance of starch edible tableware. According as this study, reference is provided for the later researcher. Results showed: 1. Without any additive, the most optimized technical parameters is 50% moisture content,3000N pressure force, 70oC initial temperature,110oC terminal temperature,6 min forming time, and 10 min keeping time. 2.Influence of plasticizers such as sorbitol,glycerol,glycol and polymer glycol 600 etc, the best plasticizers is glycerol. The second is sorbitol. Thereinto polyethylene glycol 600 is worst plasticizers. 3.Studied multiple plasticizers, when plasticizers is sorbitol,glycerol and ethylene glycol. The best multiple plasticizers is sorbitol:glycerol:ethylene glycol equal to 1:1:1. 4.When waterproof is stearic acid and paraffin. The best waterproof is paraffin. 5.Studied intensifier, when intensifier is sodium alginate and Carboxymethyl cellulose natrium. The best intensifier is sodium alginate. 6.Waterproof will be reduced when the -COO-and -COOH is increase. H2O,CH3 and CH2 will influence plasticization of tableware. The intensifier of tableware will accretion if C≡C of tableware manifold.
