Re-order Paragraphs
Arrange the sentences into the correct order.
Put the sentences in the correct order:
- As a result, produce that once spoiled within a week can now remain edible for months, fundamentally changing how far food can travel before reaching a plate.
- Building on that same underlying principle of removing the conditions bacteria need to thrive, modern food scientists introduced vacuum sealing and controlled-atmosphere storage.
- When industrialization arrived, these traditional methods were joined by canning and later mechanical refrigeration, which extended shelf life far beyond what salt or smoke alone could achieve.
- To solve this, early societies developed techniques such as salting, smoking, and fermenting, each of which slowed the growth of the bacteria responsible for decay.
- Before refrigeration existed, communities faced a persistent problem: harvested food spoiled within days, threatening survival during long winters or failed growing seasons.
