Can Yin Er soup be eaten if it is left overnight?
Yin Er is a highly nutritious supplement. However, if it is left at room temperature overnight, the nutritional content will greatly decrease, and harmful substances will be produced, posing a threat to human health.
Overnight Yin Er soup may cause hypoxia
Whether Yin Er is cultivated indoors or outdoors, it contains a relatively high amount of nitrate. The nitrate content in Yin Er itself, after drying, is lower than the international food standards. However, when cooked or soaked for a long time, nitrate can be converted into nitrite due to bacterial decomposition. When nitrite is consumed and enters the bloodstream, it oxidizes the hemoglobin in the blood, causing it to lose its ability to transport oxygen, resulting in hypoxia. In severe cases, it can even cause death.
Overnight Yin Er soup can cause anemia
When cooked or soaked Yin Er is left for a long time, it can produce nitrite. This acidic substance can transform into salts, which can affect the body's hematopoietic function, leading to insufficient blood production and long-term anemia.
Overnight Yin Er soup can be carcinogenic
Many foods, when left for a long time, can increase the nitrite content. Nitrite, when ingested into the stomach, reacts with protein breakdown products called secondary amines under the action of stomach acid, forming nitrosamines. There is also a type of bacteria in the stomach called nitrate-reducing bacteria, which can combine nitrite with amines to form nitrosamines. When stomach acid is lacking, these bacteria grow vigorously. Therefore, regardless of the amount of stomach acid, it is conducive to the production of nitrosamines. Nitrosamines have a strong carcinogenic effect and mainly cause esophageal cancer, stomach cancer, liver cancer, and colorectal cancer.
Tips
Yin Er soup is an excellent dessert in the summer. It is refreshing and not greasy when chilled. It has the functions of tonifying the spleen and appetizing, invigorating the qi and clearing the intestines, promoting sleep and improving digestion, nourishing the brain, nourishing yin and clearing heat, and moisturizing dryness. Yin Er is rich in collagen, which has the effect of moisturizing the skin. However, Yin Er is also a food rich in protein, which is prone to spoilage. Therefore, it is recommended to store it in the refrigerator and consume it within two days. If Yin Er changes color, it should not be consumed as it can cause food poisoning.
