Food processing is any method used to turn fresh foods into food products.1 This can involve one or a combination of various processes including washing, chopping, pasteurising, freezing, fermenting, packaging, cooking and many more.2 Food processing also includes adding ingredients to food, for example to extend shelf life.3, 4
Food processing includes traditional (heat treatment, fermentation, pickling, smoking, drying, curing) and modern methods (pasteurisation, ultra-heat treatment, high pressure processing, or modified atmosphere packaging). Some of the common methods are described below:
Makes food edible
Grain crops, for example wheat and corn, are not edible in their natural state. Processing techniques, such as millingand grinding, turn them into flour, after which they can be made into breads, cereals, pasta and other edible grain-based products. There are 3 types of flours depending on the processing level, choose wholegrain when possible. You can learn more about the journey of grain to bread in our ‘Gain on grain’ infographic.
Safety, shelf life, and preservation
Processing improves or even ensures food safety by removing harmful microorganisms. The main methods are pasteurisation, air-tight packaging, and the use of preservatives.
Nutritional quality
Food processing can affect the nutritional quality of foods in both ways: it can enhance it, for instance by adding components that were not present, like vitamin D (through ‘fortification’), or by lowering fat, salt or sugar. It can also cause some fibre and vitamins and minerals to be lost, for example through excessive refining, heating or freezing.

17 de abr. de 2023 · Food processing is a broad spectrum that ranges from basic methods such as chopping or freezing, to multi-step transformation of ingredients into a final food product. It brings both benefits and unintended consequences, making it a complex topic.
Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing takes many forms, from grinding grain into raw flour, home cooking, and complex industrial methods used in the making of convenience foods.
Food processing is a very broad spectrum that ranges from basic technologies like freezing or milling, to the incorporation of additives that promote shelf stability or increase palatability. As a general rule, emphasizing unprocessed or minimally processed foods in the daily diet is optimal.
Food processing is any deliberate change in a food that occurs before it’s available for us to eat. It can be as simple as freezing or drying food to preserve nutrients and freshness, or as complex as formulating a frozen meal with the right balance of nutrients and ingredients.
