Why does lemon water taste bitter when soaked in water

The bitterness of lemon soaked in water is usually related to the lemon variety, treatment method, or soaking time. The main influencing factors include residual skin oil, unremoved fruit pits, high water temperature, prolonged soaking, and variety differences.

1. Skin oil residue

Lemon skin contains natural volatile oil substances, especially bitter components that are prone to accumulate in the pits of the fruit stem and peel. When not thoroughly cleaned, these oils dissolve in water and can cause a bitter taste. It is recommended to scrub the skin with salt or soak it for a short period of time to remove any residue.

2. Kernel not removed

Lemon seeds contain glycosides such as limonin. If the kernel is not removed during slicing, prolonged soaking will release bitter components. It is recommended to use the fruit pulp after removing the core to reduce the release of bitterness.

3. High water temperature

High temperature can accelerate the dissolution of substances such as hesperidin in lemon peel, and hot water above 80 ℃ can easily stimulate bitterness. It is recommended to use 40-60 ℃ warm water for brewing, which can retain vitamin C and avoid excessive leakage of bitter substances.

4. Soaking for too long

The naringin and other components in lemon peel gradually release over time, and the bitterness increases significantly after more than 2 hours. Freshly brewed and consumed can control bitterness, and it is recommended to store in refrigeration for no more than 4 hours.

5. Variety difference

perfume lemon, Eurek and other varieties have thinner skins and lighter bitter taste, while some thick skins have higher content of limonin. Choosing seedless or low seed varieties, or drinking them with honey, can neutralize the taste.

When drinking lemon water in daily life, it is recommended to quickly rinse with fresh lemon and refrigerate the slices. 1-2 slices should be added to each glass of water to avoid direct sunlight that can cause nutrient loss. People with gastrointestinal sensitivity can drink it on an empty stomach and dilute it appropriately. Paired with mint leaves or a small amount of ginger, it can alleviate irritation. If there is persistent bitterness discomfort, check whether the lemon has spoiled or been stored improperly.
