The Budget Method, originally developed for determining food additive use limits, has been proposed as a tool for screening food additive intakes to establish monitoring priorities. Theoretical Maximum Daily Intake (TMDI) estimates derived using the Budget Method rely on assumptions regarding physiological requirements for energy and liquid and on the(More)
Food-use applications of mineral hydrocarbons (MHC) derived from petroleum sources result in dietary exposure to these compounds by consumers. Food applications of MHC, including white mineral oils, paraffin waxes, microcrystalline waxes and petrolatum, include both direct-additive uses in which the MHC is intentionally applied to the food and(More)
THE WORLD ENERGY PROBLEM AND THE BIOFUEL ENERGY PROBLEM Oxygenic photosynthesis has been promoted as a system for fuel production on a global scale to replace fossil fuels. The fundamental requirement for this to be viable is that the energy output of the system must be greater than the energy input from fossil fuels. For biofuel production, this criterion(More)
Several steps must be taken in estimating intake of (or exposure to) dietary nonnutrients such as additives, drug residues, pesticide residues, toxicants, and natural nontoxicant chemicals. The first step involves consideration of relevant characteristics of the nonnutrient, including biological activity, physical/geographical sources, distribution in the(More)
An International Interface Standard for Food Databases is under development to help overcome the technical and semantic barriers to the use of food-related databases. The Interface Standard is a system for efficient storage of all relevant descriptive information about foods. The schema for the Standard consists of ten components--food/food product(More)
