Purple cauliflower

Purple cauliflower is relatively rare, and varieties are also introduced from abroad. in 1979, the Agricultural examination Institute of the Council of Agriculture introduced 25 varieties of cauliflower from the United Kingdom. after 33 years of selection and domestication, a new variety of cauliflower suitable for cultivation in Taiwan was finally selected and bred last year, named "Tainong No. 1."

Cauliflower originated from the Euro-Mediterranean coast, but the seeds of cauliflower imported to Taiwan are not satisfied with soil and water, including lack of heat tolerance, short cultivation period, difficult seed collection, easy lodging, and so on. The growth period of Tainong No. 1 (purple cauliflower) is only 55 to 65 days, 10 to 20 days shorter than that of the original variety.

Chen Ganshu, director of Fengshan Branch, said that they introduced 25 varieties of cauliflower from the UK in 1979, when the varieties were giant monsters with a height of more than one meter and cauliflower as big as a washbasin. Because it is a temperate vegetable, it needs to be domesticated in order to adapt to the tropical climate of southern Taiwan.

Anthocyanin is a water-soluble nutrient with antioxidant and anti-inflammatory properties, which can stabilize the immune system of human body.

The Agricultural testing Institute of the Council of Agriculture also reminded that the bulbs and buds of purple cauliflower are fine, and if you cook soup, all the purple cauliflower will be scattered, which is not easy to salvage.
