Tomatoes are nutritious and delicious, making them a common vegetable on the family dinner table. When selecting tomatoes, housewives should be cautious to avoid purchasing those with uneven coloration or those infected with viruses.
Tomatoes are a frequent item in people's shopping baskets, but buying more doesn't necessarily mean buying well. The following types of tomatoes are best avoided.
Those with a green stem end. Unripe tomatoes may have a "green shoulder" (a green area at the stem end), which can contain a toxic substance called tomatine. Consuming them can result in a bitter taste and may even cause physical discomfort.
Those with uneven coloration. Such tomatoes may have been infected with viruses during their growth, leading to a significant reduction in flavor and nutritional value.
Those that are misshapen. If a tomato has a distinct pointed top or a polyhedral shape, it indicates a significant deviation from its standard variety. This is likely due to viral infection or excessive use of hormones, and long-term consumption can pose a threat to health.
Those that are hard to the touch with green seeds. Ripened tomatoes with the aid of chemicals are very hard. When broken open, their seeds are green or undeveloped, and they are juicy with less distinct separation between flesh and juice. These tomatoes are often treated with the chemical ethephon, which, while low in toxicity, can be harmful to health with long-term consumption.
High-quality tomatoes have the following characteristics: a stem end that is green and red; a smooth, well-rounded shape with appropriate ripeness; and yellowish-brown seeds with red, juicy flesh.
