Many office workers will bring meals to save money and add vegetables to their lunch boxes, but there has always been a rumor that overnight vegetables hide cancer traps!

The Centre for Food Safety of the Food and Environmental Hygiene Department announced today (April 24) the results of a survey on changes in nitrite content in cooked vegetables after storage.

The results showed that no nitrite was detected in the cooked vegetable samples after being stored in the refrigerator overnight. Even after three days of storage, the nitrite content that may cause the human body to produce nitrosamines that can cause cancer in animals is still very low.

Food safety middle finger, freezing temperature makes bacteria inactive, which can delay the formation of nitrite, but also reminds that even if harmful bacteria cannot grow at freezing temperature, some spoilage bacteria can still reproduce and spoil food, and make 4 recommendations to ensure that the remaining Vegetables, including cooked vegetables, are safe to eat.


A spokesman for the CFS said that in response to rumors in the market that the nitrite content of cooked vegetables commonly known as overnight vegetables would increase rapidly after being stored in the refrigerator overnight, the CFS collected samples of five commonly eaten vegetables, including amaranth and cabbage, from retail outlets. , Chinese cabbage, tang lettuce and jade melon were studied, and their nitrite content was measured before and after cooking.

After the center cooks the vegetables, each cooked vegetable will be divided into two groups and stored at room temperature and 0 to 4 degrees Celsius in the freezer, and on time, including after 6, 12, 24, 36, 48, and 72 hours of storage. The nitrite content was then detected.

Cooked vegetables stored in refrigerator overnight did not increase the amount of nitrite CFS: Freezing temperature makes bacteria inactive

The results showed that the nitrite content of cooked vegetables did not increase after being stored in the refrigerator overnight, while the nitrite content remained low after three days of storage.

Storage temperature is the main factor that affects the rise of nitrite in cooked vegetables. Freezing temperature will make bacteria inactive and delay the formation of nitrite.

Nitrite may produce nitrosamines that cause cancer in animals

The Center for Food Safety explained that fresh vegetables absorb nitrates from the soil to make proteins needed for growth, and bacteria in the environment can convert nitrates in cooked vegetables into nitrites.

Nitrite reduces the blood's ability to carry oxygen and may also produce nitrosamines in the body that cause cancer in animals.

However, available scientific data fails to link dietary nitrate and nitrite intake to cancer in humans.

Spoilt bacteria can multiply at freezing temperatures and spoil food

Although harmful bacteria cannot grow at freezing temperatures, the CFS reminds that some spoilage bacteria can still multiply and cause food spoilage. The public should pay attention to ensuring that leftovers, including cooked vegetables, are safe to eat.

▼Food Safety Center 4 recommendations to ensure the safe consumption of overnight dishes▼


1. Prepare only the right amount of food to reduce the amount of leftovers

2. Leftovers should be stored in the refrigerator within two hours after cooking and eaten as soon as possible

3. Before eating, the leftovers should be thoroughly reheated until the core temperature reaches 75 degrees Celsius, and should not be reheated repeatedly

4. Leftovers should not be eaten if they have been left at room temperature for more than four hours
