Method

1. Cut the red cabbage and add to a large bowl.
2. Cover with distilled water and bring to a boil.
3. Reduce heat and leave to simmer for 30 minutes until you get a rich purple extraction.
4. Remove from heat and strain through a sieve.

How do you extract anthocyanins?

This is the classical method of extracting anthocyanins from plant materials. This procedure involves maceration or soaking of the plant material in methanol containing a small concentration of mineral acid (e.g., HCl). Methanol extraction is a rapid, easy, and efficient method for anthocyanin extraction.

What solvent is used to extract anthocyanins?

Traditionally, organic solvents such as absolute methanol, ethanol, and acetone have been used to extract anthocyanins [13]. Ethanol is desirable because it is less toxic than methanol [14]. Aqueous mixtures of solvents with small amounts of acid have also been used.

Does red cabbage have anthocyanins?

Red cabbage is rich in a number of bioactive substances, including anthocyanins. The anthocyanin profile of red cabbage consisting of twenty derivatives of cyanidin glucosides was described by means of HPLC-DAD-MS/MS. The base structure of anthocyanins identified was cyanidin-3-diglucoside-5-glucoside.

How do you extract anthocyanins from blueberries?

Blueberry anthocyanins were extracted by adding 100 mg of fresh blueberries, which had been lyophilized and ground, and 1 mL of extraction solvent into a 1.5-mL micro-centrifuge tube. The sample was vortexed at high speed and left undisturbed for 1 h.

Why are anthocyanins important to a plants health?

Anthocyanins are a group of polyphenolic pigments that are ubiquitously found in the plant kingdom. In plants, anthocyanins play a role not only in reproduction, by attracting pollinators and seed dispersers, but also in protection against various abiotic and biotic stresses.

What happens when you add baking soda to red cabbage?

The cabbage juice is called an indicator because it can tell you the pH of a solution based on the color that it changes. The vinegar will turn the cabbage juice red because it is an acid (acetic acid). The baking soda will turn the cabbage juice greenish-yellow because it is a base (sodium bicarbonate).

Are anthocyanins destroyed by heat?

At temperatures ranging from 120 °C to 180 °C, both anthocyanins and antioxidant activity degraded following a first-order kinetic model.

Are beets high in anthocyanins?

While beets come in deep reds and purples, it’s not because of anthocyanins, Smith said. The purple color found in beetroot comes from betalain pigments, which replace anthocyanins in some plants. Betalains are also healthy antioxidants.
