Why are there so many leftovers of ingredients?

"Waste" always happens when you think you have plenty, and the same goes for food waste. Humans at the end of the supply chain have a large number of rich, perfect, and bright ingredients to choose from. Therefore, we do not understand the invisible consumption in the entire industrial chain and the ecological limits that we will face due to these massive wastes.

Those foods that did not meet supermarket purchasing standards but were completely edible: too-small radishes, irregular-looking tomatoes, and crooked oranges were all thrown away.

If you pay a little attention in your life, you will find that food waste is everywhere. For example, the most common sliced ??bread in supermarkets or bakeries has the crust at both ends that has been discarded before it is put on the shelf. In some conveyor belt sushi restaurants that emphasize the original flavor and absolute freshness of the ingredients, there will be slogans telling you that the lifespan of each prepared sushi here will not exceed 300 meters on the turntable. What awaits them at the end of the turntable is... A trash can that only swallows sushi.

Food that is completely edible but may be thrown away simply because of pickiness about the shape or size of bananas. These foods that are abandoned in the supply chain are called "surplus food." They are not foods that are spoiled and unpalatable, but foods that are intact and fresh. Surplus food usually comes from three sources: farms, where a large amount of raw materials are eliminated during the procurement process, usually ingredients of insufficient size and shape, or fruits that are not so pleasant in taste; supermarkets/wet markets, which are those that are picked out and left behind. No matter how plump and bright the food is, the daily loss of ingredients caused by excessive meal preparation in restaurants.

The leafy vegetables served on the table are cut off and only the middle part is left; the apples in the supermarket are all crystal clear, and the crooked melons and cracked dates have long been kicked out; many people only see jackfruit. After peeling each piece, I didn’t know that the silk and core in the middle can be used to make soup. In fact, there are many "offcuts" of ingredients in life that can be eaten, and the nutrition may be better than the main ingredients, and the taste is also very unique.

As long as the pulp has not deteriorated, bananas can be eaten if they have spots or turn black

There are four main reasons why bananas will get spots and turn black: First, mechanical damage, such as during transportation Damage occurred due to bumps during the process; second, it encountered mold. If the already "injured" banana encountered mold, it would become moldy and lead to rot; third, it turned black due to refrigeration. As a tropical fruit, bananas are often If the food cannot tolerate low temperatures, it will suffer frostbite if placed in the refrigerator; fourth, it will be overcooked if left uneaten for too long.
