Some tips to keep food fresh

Leafy vegetables are high in water content and prone to spoilage, with the preservation focus on absorbing moisture + blocking air.

- Kitchen Paper Wrapping Method: Wrap the roots (or the entire vegetable) with kitchen paper, then place it in a plastic bag and tie it tightly. The kitchen paper quickly absorbs excess moisture from respiration, preventing leaves from becoming mushy due to dampness. It can stay fresh for 5-7 days when refrigerated. If kitchen paper is unavailable, clean old cotton cloth can be used as a substitute.

- Upright Storage: Place leafy vegetables with their roots facing downward in a refrigerator crisper. Due to gravity, water tends to concentrate at the roots, slowing down leaf wilting. This is suitable for long-stemmed leafy vegetables like celery and coriander.

- Crisper Compartment Separation: For large quantities of leafy vegetables, line the crisper with a layer of kitchen paper and place another sheet between each layer to avoid localized spoilage caused by stacking and squeezing.
