Foams Resistant Starch At Temperatures Corresponding To Conventional Domestic Oven, Oven And Domestic Industry [...] Microwave Oven. The present invention concerns a foam made of starch in which a suitable [...] composite basically the water-starch is expanded high temperature for producing foams in package. The foams have outer surface smooth and rigid and internally has feeder with meshing tongued uniform and with small apertures. Such packages are resistant to various ranges of temperatures, mainly high, and can be subjected to the conventional oven or domestic food industry and microwave oven. It has been demonstrated, according to the present invention, that the amount of water of the mixture is a factor pivotal to the strength at temperatures above 40 °c foams achieved, without deforming. According to the state of the arts, all products obtained from (sec) (sec) technique (s) front require a coating to prevent burn-out of the material and packages also require a special design providing reduced their deformation such intended to not undergo tears during heating. Optional adjuvants can be added to the formulation of the inventive foam, such as plasticizers, thickeners, organic fillers and inorganic fillers to increase the mechanical strength of the foams. Pigments and dyes may be added to vary the appearance of foams and preservatives and rare earth complexes can be added with the goal of increasing the product a smart package. The packages may be [...] with hydrophobic films to increase its strength to the water. |
