Commonly used natural pigments are: lycopene, β-carotene, capsicum red pigment, gardenia blue pigment, chlorophyll, corn yellow pigment and perilla red pigment. Do you know where the 7 commonly used natural pigments come from? ?

 

 

 

Lycopene

 

Lycopene is a natural red open-chain hydrocarbon carotenoid. The pure product is needle-shaped dark red crystals. Its chemical structure is a straight chain composed of 11 conjugated double bonds and 2 non-conjugated double bonds. Type hydrocarbons.

 

Both humans and animals cannot produce lycopene. The current preparation methods are mainly plant extraction, chemical synthesis and microbial fermentation. Lycopene is a functional natural pigment that has physiological functions such as preventing various cancers, protecting cardiovascular and cerebrovascular, protecting skin, and improving immunity. It is widely used in health care products, cosmetics, food and beverages and other fields.

 

β-carotene

 

Carrots contain a large amount of β-carotene, which can be converted into vitamin A after ingested in the human digestive organs. It is currently a vitamin A supplement product (simple supplementation of chemically synthesized vitamin A will cause people to be poisoned in excess). It can maintain the health of eyes and skin, improve night blindness and rough skin conditions, and help the body protect the body from free radical damage. It should not be taken at the same time with acidic substances such as vinegar.

 

Capsanthin

 

Capsanthin is an orange-red pigment of four mushrooms that exists in ripe red pepper fruits. The larger red component is mainly capsanthin and capsanthin, which account for 50-60% of the total. The other is the smaller yellow component, the main component is β-R- Carotene, zeaxanthin, and capsicum red pigment are not only bright in color, high in color price, strong in coloring power, and good in color retention. They can effectively extend the shelf life of simulated foods, have nutritional and health effects, and are proven by modern science to be anti-cancer Features.

 

Because of its properties and functions, it has triggered a worldwide research and development boom. At present, capsicum red pigment has become a recognized and promising functional natural pigment.

 

Gardenia Blue Pigment

 

It is used for coloring hard candy, pectin, agar, pudding, machimaro, biscuits, pine cakes, cake powder, cream, ice cream, dairy products, vegetables, green beans and other cans, beverages, juices, etc. It is blue Coloring agent.

 

There is not much direct coloring in food processing. It is mainly used for compatibility with natural yellow pigments such as gardenia yellow and safflower yellow to produce green pigments of different colors. Compared with the extracted chlorophyll, use gardenia blue pigment The formulated green pigment can be controlled in hue, has good acid resistance, and can be used in acidic foods and beverages. In addition, the gardenia blue pigment can be combined with various natural red pigments to produce different shades of purple. Therefore, the gardenia blue pigment has a wider application range in food processing.

 

Gardenia blue pigments can be produced in different shades of blue pigments due to different processing techniques, ranging from sky blue to sea blue, as well as acid-resistant and acid-resistant varieties, which are suitable for different application environments. Natural pigment manufacturers

 

Natural blue pigments are rare in nature. Gardenia blue pigment is one of them. Compared with synthetic pigments, edible bright blue and indigo, its natural source and good human compatibility are a kind of natural that deserves to be promoted. pigment.

 

The cost of adding gardenia blue pigment to food, beverages and cosmetics is not high. The usage amount is between 0.005 and 0.01%, which is converted into a unit cost of about 0.025-0.05 yuan/kg. Of course, it is related to synthetic pigments. It is still higher in comparison. The unit cost of synthetic pigments in food processing is almost zero. It is precisely because of the low price that synthetic pigments are abused and overused in food, which is detrimental to people's health.

 

Chlorophyll

 

Chlorophyll is a type of green pigment contained in higher plants and all other organisms capable of photosynthesis. Both chlorophyll a and chlorophyll b are soluble in solvents such as ethanol, ether and acetone, but insoluble in water and petroleum ether. Therefore, chlorophyll can be extracted with solvents such as acetone, methanol, ethanol, ethyl acetate, etc.

Perilla red pigment

 

Perilla red pigment is a natural edible red pigment made from leaves of perilla, an annual herbaceous plant in the Lamiaceae family, which is naturally dried, and then extracted, concentrated, filtered, refined and sterilized. The main components are perillin and perillin, which are red To purple liquid or powder, with special aroma. Soluble in water and ethanol aqueous solution. It is maroon red when it is acidic, reddish-brown to brown when it is neutral, and green when it is alkaline. It has good heat resistance, light resistance and salt resistance, and has a certain anti-corrosion effect. It can be used for coloring salted plums (dyed red), pickles, fruit juices, drinks, syrups, etc.

 

Extracted from cruciferous radish, dark red amorphous powder, water solution PH<5 is orange-red, when 5--7 is blue-purple. Used in food, beverage, etc
