Fruit, meat and vegetables must all be processed. ### Importance of processing ![Importance of processing](https://image-v2.cdn.app.senecalearning.com/2018-05/8ca429d3-7c59-49ec-9c16-1bd9f68eb75d/shutterstock_404009323.jpg) - Basic processing makes food safely edible and transportable. - Processing also helps food to last longer and look nice enough to be sold. ### Poultry ![Poultry](https://image-v2.cdn.app.senecalearning.com/2018-05/7771acee-9a65-4f89-8e10-abf4a7c0a3e9/shutterstock_494739112.jpg) - Basic processing takes away internal organs and feathers. - Processors truss wings and legs (tie them to the body) so that the bird cooks more evenly. ### Meat ![Meat](https://image-v2.cdn.app.senecalearning.com/2018-05/34f2b4a8-b2fc-4d6d-848b-eb49c3e88848/shutterstock_423098833.jpg) - Processors may hang and dry meats to enhance flavour and tenderise them. - The processor will chop, slice or cut the meat. ### Fruit ![Fruit](https://image-v2.cdn.app.senecalearning.com/2018-05/3cf961fb-8c6c-4633-b559-8f32da810620/shutterstock_520695355.jpg) - Stones are taken out. - Processors squeeze fruits to make fruit juices. - Processors dry fruits to make dried products (e.g. apricots). ### Vegetables ![Vegetables](https://image-v2.cdn.app.senecalearning.com/2018-05/260ba73a-ebf1-4727-ad2d-c5b9f4650db5/shutterstock_565877869.jpg) - Processors wash vegetables to get rid of direct chemical residue and insects. - Sometimes, processors peel vegetables. - Processors sort vegetables by size and shape. ## Test yourself on Primary Food Processing - What type of processing involves converting raw foods into foods that can be eaten, cooked, or into ready-to-use ingredients? - What type of food may be hung and dried during basic processing? - Which of the following is sometimes involved in the basic processing of fruit?
