The China Consumers Association recently released a consumer advisory stating that pre-cut fruits are prone to nutrient loss and bacterial contamination, and consumers should purchase them with caution.
Modern households often have fewer members, making it difficult to finish a whole fruit at once. To address this, supermarkets offer pre-cut fruits, allowing consumers to buy half a piece, a few slices, or small fruit platters according to their needs. While convenient, pre-cut fruits are susceptible to nutrient loss and bacterial contamination.
Firstly, cutting fruits can easily lead to the loss of vitamin C.
Fruits are a primary source of vitamin C, which is prone to oxidation in the air. High temperatures and sunlight can also cause its degradation. The UK Consumers Association conducted a study on the vitamin C content of pre-packaged cut fruits sold in supermarkets. The results showed that in 13 samples, 4 had vitamin C levels that were half of the reference values.
Secondly, improper handling can easily lead to bacterial contamination.
The surface of fruits can be easily contaminated by pollutants, chemicals, or bacteria like Salmonella. If fresh fruits are not disinfected, their surfaces may harbor Salmonella. When a knife is used to cut fresh fruit that has not been washed, bacteria from the peel can be transferred via the knife.
Therefore, when buying fruit, it is advisable to purchase whole, uncut fruits whenever possible. If you must buy pre-packaged cut fruits, you should check if the packaging is intact and whether it has expired. Additionally, such fruits should be refrigerated as soon as possible after purchase.
