摘要
The feasibility of expanded polytetrafluoroethylene (ePTFE) as a packaging material for microwave-baked soy cookies was investigated in comparison with polytetrafluoroethylene (PTFE) and a susceptor incorporating elemental-metal into a receptacle (EMIR). Physical properties such as the dimensions, color, hardness, and the specific gravity of the products were measured. Soy cookies enclosed in ePTFE showed golden brown color evenly distributed with textural measurements compatible to regular chocolate chip cookies. Soy cookies microwaved in PTFE and EMIR yielded inferior physical attributes. ePTFE was capable of adequately retaining the moisture of soy cookies, indicating the potential as a packaging material for microwavable dough-based products.
