What will happen if you eat oxidized apples

Eating oxidized apples usually does not have a serious impact on health, but may affect taste and some nutritional components. Apple oxidation is mainly an enzymatic browning reaction that occurs when polyphenols in the flesh come into contact with air, and its safety depends on the degree of oxidation and the physical condition of the consumer.

Slightly oxidized apples only have a darker surface color, slightly loose flesh texture, and some loss of antioxidant components such as vitamin C, but dietary fiber and minerals are mostly retained. This type of apple has a soft and slightly fermented taste, and is usually not uncomfortable for people with a healthy digestive system when consumed in small amounts. If apples show obvious alcohol taste, stickiness, or mold spots after oxidation, it may indicate the growth of microorganisms, which may cause abdominal pain and diarrhea after consumption. For individuals with gastrointestinal sensitivity, even slightly oxidized apples may irritate the mucous membranes. It is recommended to remove the oxide layer before consumption. The deeply oxidized apple flesh is dark brown with a sour taste, indicating that it has undergone severe spoilage. At this time, not only are nutrients greatly destroyed, but harmful substances such as aldehydes and ketones may also be produced. Eating these types of apples by mistake may cause acute gastroenteritis, resulting in symptoms such as nausea and vomiting. Patients with diabetes should especially avoid eating oxidized apples, because the fermentation process may produce additional sugar. Children and immunocompromised individuals who consume moldy and oxidized apples are at risk of fungal toxin poisoning and should seek medical attention promptly.

It is recommended to soak sliced apples in light salt water or lemon water to slow down oxidation, and store them in refrigeration for no more than 4 hours. Before consumption, check if the apple has any unusual odor. For those with weak gastrointestinal function, they can choose to steam it before consumption. If you experience persistent abdominal pain, fever, and other symptoms after ingesting spoiled apples, you should promptly replenish electrolytes and seek medical attention. Although apple oxidation is common, it is still necessary to assess the safety of consumption based on individual circumstances to avoid losing out on small gains.
