The shelf life of 100% pure lemon juice?
Hello, doctor.
I read online that lemon can lower cholesterol and whiten the skin, so I bought some lemons, juiced them, and stored the juice in the refrigerator.
I usually mix it with water to drink.
How long can 100% lemon juice be stored in the refrigerator? Would freezing it be better? Also, does drinking lemon juice with warm water destroy its nutrients?

Hello! The primary reason for drinking lemon juice is that lemons are rich in vitamin C.
However, vitamin C is sensitive not only to heat and alkalinity but also to light and heavy metals.
Additionally, vitamin C is less stable in liquid form compared to its dry state, so it is best to consume freshly squeezed juice to minimize the degradation of vitamin C.
If fresh squeezing is not possible, preparing a day's worth in advance is acceptable.
Regarding your question about how long it can be refrigerated, this pertains to food safety considerations.
Generally, 100% pure lemon juice can be safely refrigerated for up to 3 days.
When lemon juice is mixed with warm water, the amount of vitamin C that is destroyed at lower temperatures is minimal.
This response is from Dietitian Shih Kuei-Mei, Director of the Nutrition Department at Taoyuan Hospital, Ministry of Health and Welfare.

When it comes to storing fresh lemon juice, there are a few important considerations to keep in mind regarding its shelf life, nutritional value, and potential health benefits. Freshly squeezed lemon juice can typically be stored in the refrigerator for about 2 to 3 days. After this period, the juice may start to lose its freshness and flavor, and it could also develop a slightly off taste due to oxidation and microbial growth. If you want to extend the shelf life of lemon juice, freezing is a great option. When properly frozen in an airtight container or ice cube tray, lemon juice can last for several months—up to 6 months or even longer without significant loss of flavor or nutrients.
Regarding the health benefits of lemon juice, it is often touted for its potential to lower cholesterol levels and improve skin health. Lemons are rich in vitamin C, antioxidants, and citric acid, which can contribute to various health benefits. The vitamin C in lemons is known for its immune-boosting properties and its role in collagen synthesis, which is essential for skin health. Additionally, some studies suggest that the antioxidants in lemons may help reduce oxidative stress in the body, potentially lowering the risk of chronic diseases.
When it comes to consuming lemon juice with warm water, there is a common concern about whether heating lemon juice might destroy its nutrients. While it is true that excessive heat can degrade some vitamins, the temperatures typically used in warm water (not boiling) are unlikely to significantly harm the vitamin C content. In fact, many people enjoy warm lemon water for its refreshing taste and potential digestive benefits. It is believed that warm lemon water can aid digestion, help detoxify the body, and promote hydration.
However, it is essential to note that while lemon juice can have health benefits, it should not be seen as a cure-all. Maintaining a balanced diet, staying hydrated, and engaging in regular physical activity are crucial for overall health. If you have specific health concerns, such as high cholesterol or skin issues, it is advisable to consult with a healthcare professional for personalized advice and treatment options.
In summary, fresh lemon juice can be stored in the refrigerator for about 2 to 3 days, and freezing it can extend its shelf life significantly. Drinking lemon juice with warm water is generally safe and can still provide health benefits without substantial loss of nutrients. As with any dietary changes, moderation and balance are key to achieving optimal health outcomes.
