food adÂ·diÂ·tives. Natural and chemical agents added to prepared foods to enhance some aspect of the food (e.g., shelf life, appearance, nutrition levels). food additives. Substances, numbered in thousands, added to food for purposes of preservation, appearance, flavour, texture or nutritional value. Without additives, much food would soon be spoiled and wasted. Common additives include vitamins, minerals and trace elements in bread, cereals, milk, margarine, table salt, fruit drinks and baby foods. Flavouring and colourings include sugar, salt, mustard, pepper, monosodium glutamate and tartrazine.
I make my own pasta dough frequently. Since my standard recipe makes around 40oz (1 kg) of dough, I always have leftover, so I've had plenty of experience with saving it. Even with eggs, pasta dough will be fine in the fridge for a week; the texture will be unaffected (if anything, it will be better). If you want to keep it longer than a week, it can be frozen for several weeks wrapped tightly in plastic wrap, and more-or-less indefinitely if you vacuum-seal it.
Fresh and Homemade Pasta: Fresh pasta can be stored in the refrigerator for 2 or 3 days. If the pasta will not be used within that time, it can be frozen and stored in the freezer for 2 to 3 months. Homemade pasta can be store in the refrigerator for 1 or 2 days or frozen for 2 to 3 months. Homemade pasta can also be allowed to dry thoroughly and then placed in a plastic bag or airtight container. The length of time it will take to dry will vary depending on the type of pasta and its size, shape and thickness.
