Purple onion: the benefits and harms, unlike the usual

Description and composition of purple onions

Lilac or Yalta onion has unique properties. It differs from standard onions with a sweet taste. Most varieties of blue onions offered in the markets are not the real Yalta variety, but belong to the steppe crops, which have standard taste, with a characteristic burning sensation.

The Crimean variety of onions was bred by crossing Portuguese and Spanish onions. It appeared in 1950. They began to cultivate it in the Nikitsky Botanical Garden. In the territory of Crimea there was Pilyaki volcano, after the eruption of which a large amount of minerals remained in the soil.

The territory from mountains to the sea is covered with stony volcanic soils. Underground are springs with spring water that feed the soil. And as a fertilizer is the litter of seabirds. Due to the presence of stony soil, onions ripen in this region even at night. Stones are heated under the sun during the day, and at night they give off heat, which increases the sugar content of the fruit.

A true Yalta variety is obtained only in several regions of Crimea:

  • village of landslide;
  • the village of Blue Bay;
  • Zaprudnoye village;
  • Nikitsky Botanical Garden.

Important! When grown in climatic zones other than Crimean, Yalta onion loses its unique characteristics. Appearance is preserved, and it becomes burning in taste.

Root crops are dense, strong. They have a flat shape. The weight of one specimen is 200–250 g. The thickness of the flakes is 0.5–2 cm. In real Crimean onions, flakes do not have more than 7 pieces. The outer scale has a saturated purple color, on the cut is white with purple layers. Real Crimean onion tastes sweet, and its juice is transparent.

Today on the markets there are purple onions of several varieties, which, like the usual one, are divided into three categories according to taste characteristics:

  • sweet;
  • acute;
  • peninsular.

Even the acute varieties of purple varieties taste much more tender than white root vegetables. Most crops of this type have salad purposes and are poorly stored. The benefits of red varieties are due to the high content of antioxidants - they are twice as many as in white varieties. Its main value is the presence of anthocyanins - substances that cause an unusual color and allow you to inhibit the development of cancerous tumors.
