Tomatoes are probably the most widely loved and popular vegetables in the world. Many believe that tomatoes are actually a fruit, but in view of their great taste and their widespread use, the battle of "fruit or vegetable" is forgotten behind. Tomatoes (Solanum lycopersicum) are vegetable species belonging to the Solanaceae family. They are grown for their delicious fleshy fruits, as annual crops. In some areas where air and soil temperatures do not fall below 0° C, they can be grown perennially.
Upon ripening, tomatoes become red, pink, yellow or orange in color, with different intensity. The bulk of the fruit varies widely - from 10 to over 200 types of fruits that may come with seeds or without seeds. The origin of tomatoes involves the equatorial rainforests of South America and they have specific requirements for the factors of their growth and development. Tomatoes are particularly demanding from irrigation, sunlight should be in abundance, but not overly strong and long.
In the eternal home of tomatoes, today we can meet their ancestors in a wild state. They are small as a walnut and are far away from the familiar taste of our tomatoes. Millennia ago, the inhabitants of Peru, Chile and Ecuador began to cultivate tomatoes. After the discovery of America, tomatoes began to enter the Old Continent. The name "tomato" comes from the word "tomalt" with which the Aztecs called the red vegetable when offering them to the Spanish merchants. Initially, however, they were grown as potted plants for decoration. Decades passed before they start to be used as food, and the first in this endeavor were the Spaniards.
Over the centuries, the varieties of tomatoes have widened considerably. Today, genetic engineering allows a wide variety of species (purple, blue, yellow, orange, etc.), with up to 500 representatives, this is a moisture-loving plant and is best grown at 25-30 degrees.
The Food and Agriculture Organization of the United Nations adopted an international standard for commercial tomatoes. According to the standard. a real tomato should be one of four shapes - round, ribbed, oblong and cherry (cocktail). The tomatoes must be undamaged, clean, fresh and not infected with pests. If tomatoes are for sale on the stem, there should be fresh, healthy and clean leaves on the stems.
Today, mass production of the tomato market is the cause of the influx of "artificial" vegetables that are far from the true taste and nutritional potential of ones grown outdoors in the warmer months. In plastic greenhouses are kept only hybrids with a high growth rate.
Scientists have even managed to identify a negative mutation gene, which leads to very high yields of tomatoes. It's about the so-called heterosis effect - when hybrids resulting from the crossing of two plant species or two breeds are more viable than their ancestors, give more fruit (wool, meat, etc.).
Composition of tomatoes
Tomatoes are an excellent source of antioxidants, lycopene and beta carotene. They are low in calories and high in vitamin C and A, which strengthen the immune system and break down fat. Their natural color has a powerful lycopene antioxidant. Tomatoes have a huge wealth of vitamins, minerals and other nutrients. Daily, we need a large tomato, in order to obtain almost all need as far as vitamin C and vitamin A go. Tomatoes contain 17 times more iron than milk, twice as much as eggs and three times more than fish. Ripe fresh tomatoes contain 2-3 times more vitamin C than green ones.
There is a variety in the chemical composition of tomatoes and they vary depending on soil and climatic conditions. Tomatoes are 94.5% water, 0.9% protein, 3, 5% carbohydrates, insignificant percent starch, 0, 7% cellulose, organic acids (citric, malic, oxalic). They contain minerals such as potassium, phosphorus, calcium, magnesium, sodium, iron, etc.. They have 30 mg vitamin C, 0.60 provitamin A, 0.85mg vitamin E, 0.50 mg vitamin C, 0.50 mg vitamin PP. Vitamins B1 and B2 are found in smaller quantities.
Selecting and storing tomatoes
Most taste and health benefits of the tomato come from ripe ones, not those that have been picked green and ripened in a crate. This is an important rule that must be observed when selecting tomatoes, though today it is confined almost exclusively to the "artificial" ones. When buying tomatoes, try to find balanced and deep red, fleshy and juicy ones. When it is chewed, it should not crunch. Because of the deterioration of the taste of tomatoes in recent years, consumers buy more pink tomatoes that are more expensive, but taste relike real traditional tomatoes.
If you choose a real tomato, it can be stored in a cool place for a few days. After this period, their sugars start to rapidly break down, resulting in increased acidity and then, the tomatoes are inedible. The pectin in them breaks down in parallel and, they begin to rot and decay. Uncolored tomato is to be kept at about 10 degrees.
Tomatoes should be cut immediately before use with a stainless steel knife, because they are perishable. This is due to vitamin C, which is highly unstable and quickly ruins in the presence of light and air, and from contact with metal. Proper pasteurization and proper storage of tomato juice and canned tomatoes may retain their nutritional values for approximately two years. Associates in New Delhi (India) created a new variety of genetically modified tomatoes that are stored for much longer than conventional tomatoes. Ordinary tomatoes begin to wilt and spoil after 15 days storage, the fruit of the new variety resistant GM tomato remains fresh for 45 days.
