the norm

Quince is a small tree or shrub with large yellow fruits that beckons passers-by with a sweet-tart smell from late summer to mid-autumn. The Latin name of the plant Cydonia comes from the name of the city of Cydon, located on the island of Crete, where it was widely cultivated in the first millennium BC. Interestingly, at that time, King Charlemagne ordered to plant bushes with lemon fruits throughout France.

What is quince?

The fruit of a tree of the Rosaceae family is a close relative of apples and pears. A distinctive feature of the fruit is that it is almost impossible to eat it fresh. It has a tart taste and is too viscous, because of this it can disrupt digestion, so it is recommended to eat lemon fruits of an exotic tree only in boiled, baked or canned form.

It is curious that the word “marmalade” comes from the Portuguese name for quince – “marmelo”.

Historical background

Quince fruit has been identified with the symbol of love and fertility since ancient Greece. According to legend, the lemon fruit, radiating a marvelous aroma, was presented by Paris to Aphrodite. Since then, it has been called the “golden apple” or the “apple of discord.” In medieval Europe, giving this fruit meant confessing one’s feelings.

Initially, quince, along with mountain ash, pear and apples, belonged to the genus Pear. However, there were many differences between these fruits, which forced scientists to separate the fruit into a separate genus Japanese pear. It included the following types of quince: Chinese, evergreen, chaenomeles. Despite a number of common features (tough flesh, a large number of seeds, a specific strong aroma, a stony structure), the plants had numerous differences.

In 1822, each species of quince was separated into a separate monotypic genus: Japanese (quince) – Henomeles, Chinese – Pseudocidonia, evergreen – Quince.

Archaeologists have established that the tree that gives the “golden apples” is one of the oldest “tamed” plants. It has been established that the first cultivated plantings of quince appeared in Asia four thousand years ago. Since then, the fame of the fragrant fruit has spread to other continents and countries. Today quince is cultivated in forty countries of the globe.

The areas allocated for landing quince:

  • Turkey – 9800 hectare;
  • Uzbekistan – 7000 hectare;
  • Argentina – 3200 hectare;
  • Azerbaijan – 3100 hectare;
  • Serbia – 2200 hectare;
  • Algeria – 1800 hectare;
  • Spain – 1400 hectare;
  • Russia – 1000 hectare.

In addition, fruit-bearing trees can be found in northern Iran, Latvia, Belarus, Crimea.

The quince growing area is limited by average annual temperatures of +8 – 9 degrees Celsius, the absolute minimum is -15 degrees.

General characteristics

The height of an adult fruit tree reaches five meters. Quince leaves are similar to apple leaves, inflorescences are large white or pink. The fruits, depending on the variety, are spherical or pear-shaped and yellow, light lemon or dark yellow in color. The size of the fruit resembles a large apple. The peel of quince is covered with small villi, the pulp is low-juicy, astringent, sweetish, fragrant and very hard. The seeds are reddish-brown with a mucilaginous shell on the outside, contain a poisonous substance (amygdalin), which gives the fruit the smell of bitter almonds.

The value of quince fruits is determined by the significant content of a complex of vitamins, monosaccharides, and biologically active substances. They have healing properties, help with eye diseases, sclerosis, hypertension, tonsillitis, soften the skin, have a powerful anti-inflammatory, tonic, antiseptic effect. [1].

The ripening time of fragrant fruits is September-October.

Today fruit is used in:

  • food industry (for the manufacture of jam, marmalade, jam, candied fruit, meat dishes sauce);
  • medicine (as an antibacterial, diuretic, antiulcer agent) [2];
  • cosmetology (for cleansing oily skin, improving complexion, strengthening hair).

Common varieties

The scientific classification of the fragrant tree of the Rose family has changed with the improvement of taxonomy and the development of botany. According to modern data, the Quince genus is monotypic, consisting of a single representative of the common quince (oblong). It is represented by five varieties or garden groups that differ in biological characteristics, ripening rate and fruit shape.

These include the following types:

  • decorative (marble and pyramid);
  • garden (pear-shaped, apple-shaped, Portuguese).

Common quince varieties and areas of their growth

Early:

  • “Muskatnaya”, North Caucasian region;
  • “Gold of the Scythians”, North Caucasus;
  • “Persian sugar”, Crimea, Volga region;
  • “Van Diemen”, Crimea;
  • “Kulyab apple”, Tajikistan.

Mid-season:

  • “Krasnoslobodskaya”, the Volga region, the Caucasus;
  • “Gurji”, Dagestan;
  • “Ktyun Jum”, Southern Dagestan;
  • “Kuban”, Crimea, Russia, Caucasus, Moldova;
  • “Teplovskaya”, Lower Volga region;
  • “Amber Krasnodar”, Caucasus;
  • “Be-gi-Turush”, Tajikistan.

Late-ripening:

  • “Zubutlinskaya”, Dagestan, Caucasus;
  • “Vraniska Denmark”, the territory of the former Yugoslavia;
  • “Jardam”, Azerbaijan, Turkmenistan;
  • “Micha fertile”, America, Turkmenistan;
  • Tursh, Armenia;
  • “Ahmed Jum”, Dagestan;
  • “Champion”, Crimea, Russia.

Pear quince varieties are more juicy and sweet, and apple-shaped ones are early ripening.

Four trumps

The first thing that catches your eye is the size of the fetus, which rarely weighs less than 500 grams, and sometimes reaches 4 kilograms. This is the unconditional trump card of this fruit tree, since such heavyweights are not found among apples and pears. Interestingly, it is the large size of the light lemon fruit that attracts thieves to quince gardens. However, after tasting, they immediately throw them away. And all because the villains do not even realize that the value of quince is in its magnificent, strong, persistent aroma, and not in taste. This is her second advantage.

Due to this feature, quince is used in cooking to give characteristic bitter-sweet notes to compote, jam, jams, pastries.

The third trump card of the unusual taste of the fruit is its high biological value. The peel and pulp of quince are saturated with nutrients: vitamins, macro-, microelements, organic acids, pectins, saccharides [3]. They supply the body with useful compounds and remove harmful heavy metals: uranium, zinc, lead.

Interestingly, the therapeutic effect of the boiled fruit is 2-3 times stronger than fresh. [4].

The fourth trump card of the quince is the possibility of implanting a pear. This improves the taste, color of fruits and makes it possible to get two fruits from one tree.

Quince and pregnancy

Expectant mothers are allowed to consume the fruit boiled, subject to the individual tolerance of the product.

Quince is a source of vitamins for pregnant women, which, thanks to its unique properties, eliminates:

  • toxicosis;
  • anemia;

In addition, quince contributes to the full development of the fetus. However, due to the excessive acidity and high content of vitamin C, it is not recommended to give this fruit to children under three years of age, since the child’s body is not yet adapted to digest such a “heavy” product.

Cooking application

Quince is widely used in the food industry in different countries. The aroma of the raw fruit is unusual, but pleasant. It traces notes of tree bark, unripe pear, autumn flowers, sour apple. Quince sometimes smells like a tropical fruit. Jams, jellies, elite white wines (Chenin Blanc, Sauvignon Blanc, Сhardonnay), marshmallows, candied fruit, marmalade, sauces, gravies for meat dishes are made from it. To give a sour taste, quince slices are added to borscht, cabbage soup, soup, pickle, pastries or even tea. In ancient Greece, the miracle fruit was baked with honey, and in the east they were stuffed with ground beef and beans.

Fresh fruit is too hard, contains bitter tannins. But stewed quince is much sweeter, softer and healthier. Prolonged heat treatment gives a light pink, reddish or deep purple hue to the Asian fruit.

Before cooking, all the seeds are extracted from the quince, since they contain a toxic component – amygdalin, which, when released into the stomach, turns into cyanide and leads to poisoning of the body.

Remember that the value of the fruit lies in the subtle aroma concentrated in the peel. In Transcaucasia and Central Asia, fruit pulp is added as a seasoning to all national dishes. They even stew meat with it, so when cooking quince, a very thin layer of peel is removed to preserve the smell. In Spain, marmalade is made from the fruit, which is usually eaten with spicy cheese. Together with meat and rice, they stuff the bird with it.

In Iran, quince is used to make canned syrup, which is usually diluted with lime juice or water before consumption.

Application in medicine

Due to its beneficial properties, the fragrant lemon fruit has a beneficial effect on the psyche, respiratory organs, gastrointestinal tract, and immunity. Quince has a tonic, hemostatic, enveloping, softening and antiseptic effect.

It is used to prepare a medicinal syrup for anemia, an aqueous decoction to improve the functioning of the digestive tract, an infusion for the treatment of bronchial asthma, and tea to normalize the activity of the kidneys.

Recipes for the preparation of medicinal products from quince:

  1. Fruit syrup. This is an effective remedy for anemia, heavy uterine bleeding. To prepare the syrup, carefully grind the quince fruits, fill them with water, bring to a boil, cook until softened. After that, squeeze the juice out of the pulp. Boil the drink until the syrup is thick. Take 20 milliliters before meals three times a day.

Interestingly, fresh quince fruits contain a lot of iron, so they are recommended for people to treat and prevent iron deficiency anemia.

  1. Mucus from seed. Viscous liquid is used as antitussive, enveloping, softening, expectorant, sedative. It facilitates the course of gastric ulcer, helps with bronchitis, colitis, diarrhea. Slime is obtained by shaking the seeds of quince (5 grams) with boiling water (150 milliliters) for 10 – 15 minutes. Take 50 milliliters three times a day for 30 minutes before meals or in between meals.
  2. Water infusion from the leaves. It weakens and sometimes stops an attack of bronchial asthma, relieves inflammation in diseases of the stomach, reducing intestinal motility. To prepare the infusion, pour 5 grams of leaves with 200 milliliters of hot water, put in a water bath. Boil for 15 minutes. Leave the resulting broth for 45 minutes, then strain. Add water to the healing drink until the initial volume is obtained. Take 15 – 30 milliliters four times a day before meals.
  3. Seed decoction. It is used to treat skin diseases, sore throat, alleviate gastrointestinal problems. Cooking method: add 5 grams of quince seeds to 300 milliliters of cold water, heat in a water bath (to a boil). Cover the broth, wrap with a towel, leave for two hours. After the specified time, strain the jelly. Take a decoction of 100 milliliters before meals three times a day.

During the preparation of the enveloping potion, make sure that the seeds are intact. Damaged seeds should not be used, as they release toxic substances and pose a threat to human health.

A characteristic feature of the violation of the integrity of seed shells is the appearance of the smell of bitter almonds.

  1. Vitamin preparation. A kilogram of fresh fruit, wash and peel. Each fruit is divided into four parts, all scroll through a meat grinder. In the resulting mass, add a kilogram of sugar, mix. “Canned” vitamin mixture retains its beneficial properties, nourishes the body, refreshes and invigorates. Keep the workpiece in the refrigerator. Take 5 – 10 milligrams, mixed into green tea.

Fruit syrup, mucus, seed decoction, water infusion from the leaves cannot be stored for more than three days in the refrigerator, because pathogenic flora multiply quickly in them, which spoils the product.
