Natural Color Capsules: Where do the Colorants Come From?

Posted by CapsCanada on 21-Dec-2022 5:59:27 PM

When we talk to nutritional supplements makers, they often tell us that their customers are demanding “clean labels” and products that are as “natural” as possible. K-CAPS® vegetarian empty capsules with natural colorants were developed to meet this demand. After all, when your customers are scrutinizing every aspect of your product, the empty capsules that your fill material is encapsulated in need to be as natural as the fill material itself.

All K-CAPS® empty capsules share some important characteristics

 

The good news is that the quality and dissolution properties of K-CAPS® natural color capsules are the same as that of K-CAPS® made with synthetic colorants…they’re simply a more natural product.

 

Plus, whether made with natural colorants or synthetic colorants, all K-CAPS® empty capsules are…

 

  • Made from HPMC, a plant-derived material
  • Vegetarian and Vegan Registered with the Vegan Society
  • Kosher and Halal certified
  • Non-GMO
  • Free of preservatives, allergens, and starches

K-Caps: Natural Colorants

What are the sources of the colorants used to make these natural color capsules?

 

As the name implies, natural colorants are derived from natural sources. Here’s what you need to know about the source of each of the natural colorants that CapsCanada uses to make natural color capsules…

 

Annatto

Bixa Orellana

Annatto natural colorant is an aqueous alkali that is extracted from the spiney seed pods of the annatto bush. The solution is pH adjusted by the addition of potassium hydroxide and then spray dried using dried glucose syrup and maltodextrin as carriers.

In the European Union, annatto natural colorant is also referred to as norbixin.

 

Brown Carrot

Caucus carota L. and Daucus carota ssp. Sativus var. atrorubens

 

Brown carrot natural colorant is not made from brown carrots. Instead, it is made from purple carrots and black carrots. To control the pH, citric acid is added at the time of harvest. It is then concentrated and dried without the use of any carriers.

 

Caramel

Caramel natural colorant is a liquid that is obtained by the controlled heat treatment of plant-based glucose in the presence of ammonium sulfite.

 

Purple Sweet Potato

Dioscorea alata

 

Purple sweet potato natural colorant is made from purple sweet potatoes. To control the pH, citric acid is added at the time of harvest. This natural colorant is then concentrated and dried without the use of any carriers.

 

Red Radish 

Raphanus sativus

 

Red radish natural colorant is produced from red radishes. To control the pH, citric acid is added at the time of harvest. This natural colorant is then concentrated and dried without the use of any carriers; the end result is non-hygroscopic and readily soluble.

 

Safflower

Carthamus tinctorius

 

Safflower natural colorant is a concentrated aqueous extract made from the flower of the safflower plant.

 

Sodium Copper Chlorophyllin

Festuca arundinacea and Medicago sativa L.

 

Sodium copper chlorophyllin natural colorant is an extract obtained from vegetables.

 

Spirulina

Arthrospira platensis

 

Spirulina natural colorant is extracted from Arthrospira platensis, which is an edible blue-green algae. The colorant is obtained via water extraction and then spray dried to form a powder.

 

Vegetable Carbon

 

Vegetable carbon natural colorant is produced by the carbonization of vegetable material such as wood, cellulose residues and peat, as well as coconut and other shells. The activated carbon produced is then milled by a roller mill. The resulting highly-activated powdered carbon is treated by a cyclone. The fine fraction from the cyclone is then purified via a hydrochloric acid washing, neutralized and then dried.

 

The natural colorant produced using this method is traditionally known as “vegetable black.” To create a colorant with higher coloring power, the fine fraction is subjected to further cyclone treatment or extra milling, followed by acid washing, neutralizing and drying.
