- plastics one of a variety of plastics
- polystyrene cup for example, is about 500 years, and each American disposes an
- polystyrene is made by chemical
- Paper and paperboard are made from wood pulp, which is a renewable
- cooked, unmodified starch is inherently water soluble.
- aqueous fluids or vapor are not present (e.g., dry or deep-fried items).
- aqueous e.g., beverages, soups
- aqueous phase e.g., thin
- sauces, vegetables heated in water or (3) give off water vapor as they cool (e.g., rice
- Another approach is to protect the starch from contact with aqueous fluids or vapors by applying water-resistant coatings or films to the surfaces of the food service items, essentially forming a laminated structure in which a water- sensitive core is sandwiched between layers of a biodegradable water-resistant material.
- Many biodegradable coatings are costly to obtain and difficult to apply, thus increasing manufacturing cost and complexity and reducing the percentage of acceptable finished products.
- Baked unmodified starch is typically quite fragile and brittle when dry, but
- fiber is often added to the formulation to increase the flexural strength
- inorganic mineral fillers e.g., calcium
