Fresh produce often seems to last longer at home during winter than in summer. The reason is simple: temperature has a major impact on ripening, ethylene production and eventual decay.
Warmer kitchens create more stressful conditions for fruit and vegetables. As temperature rises, produce can release more ethylene — the natural plant hormone involved in ripening. At the same time, surrounding produce can become more responsive to ethylene, accelerating softening, colour change and spoilage.
Temperature and ethylene work together
Ethylene is naturally produced by many fruits and vegetables. In small amounts, it helps produce ripen as intended. However, when ethylene builds up — especially in warmer conditions — freshness can decline more quickly.
This effect is most noticeable when different foods are stored together.
Common ethylene-producing fruits include:
- Bananas
- Apples
- Pears
- Stone fruit
- Avocados
In summer, these items may release more ethylene. Nearby produce can then ripen faster, particularly if it is stored in a warm fruit bowl, cupboard or kitchen.
Why winter slows the process
Cooler winter conditions help slow biological activity. This means produce generally releases less ethylene and responds to it more slowly.
As a result:
- Ripening becomes more gradual
- Softening is delayed
- Visible deterioration takes longer
- Shelf life can be extended naturally
Season makes a difference, but temperature is only part of the picture. Managing ethylene exposure is also important.
Managing freshness at home
The same principles used throughout the fresh produce supply chain also apply in everyday kitchens. By reducing excess ethylene around stored produce, ripening can be moderated without stopping it completely.
Products such as Lakeland StayFresh Sheets, made using RYPEN Technology by It’s Fresh, are designed to absorb excess ethylene around fresh produce. This helps limit ethylene build-up, supporting slower deterioration while still allowing fruit and vegetables to ripen naturally.
By managing the relationship between temperature and ethylene, households can help fresh produce stay fresher for longer, reduce waste and get more value from every shop.
The takeaway: winter helps, but ethylene management matters all year round.
