Ultra-processed food: what is really in it
A Greggs Cheese & Onion Bake is made from 2 main components: puff pastry and cheese and onion filling. Each is prepared separately, often using centrally produced ingredients, before being assembled and baked in shop ovens.
Reading the ingredient detail closely, a Greggs Cheese & Onion Bake contains emulsifiers and modified starch. These are not used to add nutritional value. Emulsifiers help fat-based and water-based ingredients in the pastry blend together and stay blended. Modified starch thickens sauces and gravies so they hold together and do not turn watery when baked or reheated.
None of this means the ingredients are unsafe; all additives used are approved for use in UK food. What it indicates is the degree of industrial formulation involved. A home-baked equivalent, made with fresh pastry and a freshly made filling in one kitchen, would typically involve far fewer steps and far fewer additives. The version sold at Greggs reaches a comparable end result using centrally produced pastry and fillings, baked fresh in shop ovens, with a number of functional additives designed to keep the product consistent across thousands of shops.
Cheddar and processed cheese, onion, mustard, seasoning, modified starch (thickener)
Looking at the ingredient list rather than just the nutrition panel tells a different story. Even where individual macros look moderate, the number of separately manufactured components, and the additives used to bind, thicken, preserve and standardise them, place almost every item in this range in the most processed food category under the NOVA classification system.
Processing (NOVA classification)
A Greggs Cheese & Onion Bake falls into NOVA group 4, ultra-processed food. The NOVA classification system groups foods by the extent and purpose of the processing involved, rather than by their individual nutrients. Group 4 covers products that are formulated mostly or entirely from substances derived from foods, plus additives, using a series of industrial processes with little or no whole food remaining recognisable in the final product. In this item, that includes emulsifiers and modified starch, on top of the laminated pastry and centrally prepared filling typical of the range. This classification applies to almost all bakery items at Greggs, and indeed to most bakery and convenience food generally; it is not a finding specific to this item.
