How does cauliflower get purple

Cut florets will last four to seven days, and rice should be used as soon as possible, within two days max. Purple cauliflower is interchangeable with white cauliflower in taste and texture, so any recipe you have that calls for cauliflower can be swapped with no adverse effects.

But obviously you eat with your eyes first, so think about applications where the color works to your dish's advantage. Same for pickling. It will get somewhat muted in cooking if boiled or cooked past crisp-tender, so you won't get an intense violet mash, for example. But the color can be very appealing to kids, so if you have little ones who don't traditionally love their veggies, purple cauliflower can be a fun way to get them excited about vegetables.

There are other reasons why cauliflower heads may become discolored. The presence of diseases like bacterial soft rot , cauliflower mosaic virus, and powdery mildew may cause not only curd discoloration, but physical irregularities as well. They are brown, black, or gray, with fuzzy, weepy, or dusky appearances.

Most affect the leaves as well, and are often preceded by an insect infestation , or extended wet weather. In addition, developing curds that are not blanched and receive direct sunlight may scorch and develop brown patches. When there are hints of purple with no visible signs of insect infestation or disease, you may harvest and enjoy.

And finally, if the sun has scorched portions of the curds to a charred brown, you may cut off the damaged portions and consume the unblemished florets. As for flavor, white cauliflower tends to be on the bitter side in comparison to boldly pigmented cultivars. Those that blush due to heat exposure may become more bitter, but some folks say that little bit of color makes them all the sweeter. The crop may not be supermarket-worthy, but it is edible, and may even be a little sweeter.

For the best results, plan well. Grow plants suited to your region, avoid maturation during summer heat, and inhibit temperature fluctuations and direct sunlight with floating row covers. And finally, blanch varieties that require it, and assist modern cultivars with the practice as needed. Contribute Today. What you see: White cauliflower with some random purple patches in the branches and stem What it is: Bonus colors from anthocyanins, common plant pigments Eat or toss: Eat!

This is harmless. In fact, anthocyanins are good for you! Third, these purple plant pigments—known as anthocyanins —are antioxidants, so this cauliflower is packing some bonus nutrition.

That is, if you manage to eat the pigments. Boil the cauliflower and the purple will dissolve away, leaving the veggie white or a little grayish. Jim Myers, a vegetable breeder and horticulture professor at Oregon State University, told me that this is a common genetic fluke in cauliflower production.

Some plants produce anthocyanins in certain areas if conditions are right. In this dissertation , Li Wei Chiu writes that high light exposure, nutrient deficiency, wounds and low temperatures have all been shown to trigger anthocyanin production.

Green cauliflower contains more beta carotene than white cauliflower, but less than broccoli. Cooks Illustrated experimented to find out the best method of preparation for holding color. They found that the orange cauliflower proved to be the most stable; the orange pigments are not water soluble or sensitive to heat.

The chlorophyll in the green cauliflower is heat sensitive just like broccoli; overcooking will cause the cauliflower to become brown. There are lots of recipes available online for preparing the colored cauliflowers. Enjoy the color! I enjoy spending time with family and friends, gardening, quilting, cooking, sewing, and sharing knowledge and experience with others.
