The main spoilage factors for bakery and dried products are mould growth and chemical breakdown.
Fermentation may also cause problems in pastries or breads which have been filled, but as the water activity of bakery products is low, the growth of micro-organisms other than mould is seldom a problem.
The fat within dry foodstuffs such as cocoa products, crisps, peanuts, coffee and spices as well as powdered milk and potatoes makes them sensitive to oxidation and rancidity. Mould, oxidation and rancidity can be effectively controlled by packaging the produce in a modified atmosphere. Modified Atmosphere Packaging (MAP) is especially suitable for rye bread, sweet bakery products, pies, pre-baked bread, crisps and peanuts.
Cryogenic freezing and cooling is ideal for many bakery products and is typically used to freeze part-baked breads and fast-freeze rolls, pretzels and prepared bakery products.
