The definition of natural pigment

A pigment is the material that changes the color of light it reflects as the result of

selective color absorption. This physical process differs from fluorescence,

phosphorescence, and other forms of luminescence, in which the material itself emits

light.

Natural edible pigment is derived from natural resources such as natural plant roots,

stems, leaves, flowers, fruits and animals, microorganisms such as edible

pigment, food coloring, is a mixture of many different components. As the wide variety

of sources, composition complex variety of natural pigments.

In biology, a pigment is any colored material of plant or animal cells. Many biological

structures, such as skin, eyes, fur and hair contain pigments (such as melanin) in

specialized cells called chromatophores. Many conditions affect the levels or nature of

pigments in plant, animal, some protista, or fungus cells. For instance, Albinism is a

disorder affecting the level of melanin production in animals.

Pigment color differs from structural color in that it is the same for all viewing angles,

whereas structural color is the result of selective reflection or iridescence, usually

because of multilayer structures.

According to extraction methods, the natural pigment can be divided into four main

categories: namely, plant and animal body formed by the juice or liquid solvent

extraction or solid color; body of animal and plant dry powder obtained by grinding

pigment; by microbial fermentation , metabolites separated into liquid or powder for

further processing of the pigment; using natural products as raw material, obtained by

the enzyme and the pigment.

A source of natural pigment

Generally derived from the natural pigment components such as the Red Beet ,

Grape and Pepper of these foods has been the recognition and acceptance of

consumers, therefore, use of these food sources of natural pigments to be better

consumers, better and safer to use. Most come from plant pigments.

  The characteristics of plant pigments

The vast majority of plant pigment without side effects, high security. Most of the

anthocyanin class of plant pigments, carotenoids, flavonoids compounds, are a

class of bioactive substances, is herbal and health food products in the functional

active ingredients. In view of plant pigments as a coloring additive used in food,

medicine and cosmetics, with capacity of less than the amount of medical and

health care products effect the ratio. In the health food applications, this type of

plant pigment respectively to play in strengthening the body's immune function,

anti-oxidation, reducing blood lipids and other auxiliary role; in ordinary foods, so

can play an enhanced role in support of nutrition and anti-oxidation.

  The application of natural pigments

In the development and application of natural pigments, the China's natural food

coloring product times the output of caramel largest annual output accounting for

about 86% of natural food pigments, mainly for the domestic brewing industry and

beverage industry. Followed by the red yeast red, sorghum red, gardenia yellow,

radish red, sodium copper chlorophyll, carotene, cocoa shell color, turmeric, etc.,

mainly used in the preparation of wine, sweets, cooked meat products, jelly, ice

cream, artificial crab meat and other foods. With the further improvement of living

standards of our people and return to nature, eating all-natural based products

will become the mainstream of food consumption in the future, the domestic food

industry demand for natural food coloring will continue to grow and will also open

up the natural pigment in the pharmaceutical , Japan and so on in the broader

fields of application.

  Natural pigment in the textile industry

In addition to the natural pigment widely used in the food industry, the textile,

apparel, home textiles industry has been widely used as natural dyes, but not all

pigments can be used as dye. Textiles need washing, friction fastness, fastness,

light fastness there are more requests. However, as a natural plant extract the

pigment dye to follow the trend of the times.

  The types of food coloring

According to their sources of food coloring can be divided into two main categories:

(1) natural pigment;

(2) synthesis of pigment.

China's approval of allowing the use of natural pigments for food, 48 species, including

natural β-carotene, beet red, turmeric, safflower yellow, more orange-red lac red, chili

red, orange pepper, caramel color (without ammonia production ), caramel color

production of caramel color (plus ammonia production), red rice red, yellow

plant carbon black, Buddleia yellow, Lithospermum red; Tea yellow pigment: Tea green

pigment, citrus yellow, marriage Annatto (Redwood Su / Su-down rosewood) Cochineal

red, iron oxide (black) and so on. These natural pigments from plants, microorganisms

or animals to use physical methods to extract the edible parts of crafted, in that 48

varieties of natural pigments, at present China's major production, use and export of 40

kinds of products, including caramel, chili red, β-carotene, sodium copper chlorophyll,

sorghum red, red yeast rice and so on.

We can imagine that the plant flowers if there is no pigment, the bees will be

difficult to find, but cannot be pollination, plants cannot reproduce. Animals, too, a

few million years, Nature of these animals are ultimately derived from edible

plants, natural pigment, and constantly evolving, these natural pigments gave

them a bright color, abundant strength, and lasting vitality to enable them to

produce offspring until now, while the All of these carotenoid pigments in the feed

processing would be oxidized away. This is the artificial breeding animals and

wild animals, one of the most fundamental difference between "a serious lack of

natural pigment."

Affect food factor in the use of natural pigments

When people use natural pigments, you must consider the following factors, as a

chosen reference:

The color of needs: it may require a mix of two or more kinds of pigments, in

order to meet the color requirements.

when the kinds of foods in selling, whether it can meet the country's regulatory

laws.

The physical form needs: In general, the cost of liquid natural pigment powder

were lower than that.

food ingredients: The main consideration fat or protein content and the presence

of tannin, the former concerned with the solubility of natural pigments; the latter

exist, would limit the use of anthocyanins; but also determines the product is

clear and transparent, or was cloudy.

processing conditions: the principal consideration for the heating temperature

and time.

pH: The pH of food can affect the stability of pigment, so you can determine the

choice of pigment type and color rendering.

Packaging: Packaging oxygen permeability and light transmittance can affect the

stability of natural pigments, which could also affect people's choice of natural

pigments.

product sales life and storage conditions.

infusions can be added to the oil or water portions of your formulas, yielding a range of

lovely earth toned colors.

12

To create an infusion, simply warm your or oil, place herbs

into the liquid, and Steep for 20 to 40 minutes. After the infusion has taken place, the

patch must be strained from the liquid. You can use a Cheese Cloth or a Fine Mesh

Strainer to strain the plant material from the liquid. Alternatively, you can avoid the mess

by placing the herbs into a Large Tea Bag or a Large Mesh Tea Ball. The colored oil or

water can be added drop by drop to your formulas or it can be substituted for a portion

of the water or oil called for in a recipe.

Experimentation is the best way to find your favorite shades of color. While these herbs
