How Mova does on its tests: [the lesson at school](https://md.mova.elamur.ai/free/en/school-run/technology/3-crisps-bread-cereal-and-dairy/). - [1](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/1/) — Cameras watch the crisps falling, and tiny puffs of air blow out any burnt or green one in a fraction of a second, while bread rides through a tunnel oven longer than a swimming pool. - [2](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/2/) — Much of food-factory work is really about germs: milk is heated to kill them, yoghurt has friendly ones added on purpose, and soup is sealed in a can before it is heated so no new germs can get in. - [3](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/3/) — Think of the crisp bag that seems half empty: it is full of nitrogen gas, which keeps the crisps fresh and stops them being crushed. - [4](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/4/) — Crisp potatoes are washed, peeled by spinning against rough rollers, sliced very thin, fried or baked, flavoured in a tumbling drum and bagged. - [5](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/5/) — Crisp bags are filled with nitrogen gas instead of air, which keeps crisps fresh and cushions them. - [7](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/7/) — Green patches on potatoes go with a natural poison, which is why green crisps are removed; one small green crisp is very unlikely to harm anyone, but factories take them out to be safe. - [8](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/8/) — Bread is flour, water, yeast and salt mixed in huge mixers, shaped, left to rise in warm cupboards, baked, cooled, sliced and bagged. - [9](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/9/) — Yeast is a tiny living fungus (a relative of mushrooms), and the bubbles in bread are the gas it gives off. - [10](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/10/) — A tunnel oven has a moving belt: raw dough goes in at one end and comes out baked at the other, and some tunnel ovens are longer than a swimming pool. - [11](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/11/) — Biscuit dough is rolled into a sheet, cut by a roller with shapes, baked in a tunnel oven and wrapped; the little holes in crackers let steam out so they bake flat. - [12](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/12/) — Cereal flakes are cooked grains squashed flat between heavy rollers and toasted; puffed grains are heated under pressure and then released so they pop; cornflakes were invented in the 1890s at a health resort in the USA. - [13](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/13/) — Yoghurt is milk heated to kill germs and then kept warm for hours with friendly bacteria that thicken it; the bacteria are alive, and the fridge keeps the yoghurt from going off. - [14](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/14/) — Milk is cooled at the farm, carried by tanker to a dairy and heated briefly to kill germs, which is called pasteurising after Louis Pasteur, who studied germs in the 1800s. - [15](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/15/) — Frozen pizzas get toppings from machines, sometimes falling like snow from hoppers, then are frozen fast in a cold tunnel, because fast freezing makes small ice crystals that damage food less; they must be cooked until hot all the way through. - [16](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/16/) — Canned food is sealed in the can first and then the whole can is heated, so it keeps for years without a fridge; canning was invented about 200 years ago, and the first cans were opened with a hammer and chisel because the can-opener came later. - [17](https://md.mova.elamur.ai/free/en/corpora/school/technology/3-crisps-bread-cereal-and-dairy/17/) — Do not eat from a can that is swollen or badly dented along its seams. - ← previous: [Chocolate and sweets](https://md.mova.elamur.ai/free/en/corpora/school/technology/2-chocolate-and-sweets/) - next →: [Bottles, cans and recycling](https://md.mova.elamur.ai/free/en/corpora/school/technology/4-bottles-cans-and-recycling/) - ↑ back to [Technology](https://md.mova.elamur.ai/free/en/corpora/school/technology/)
