Food colours are standard in our everyday lives, and they may even be found in meals and drinks we wouldn’t anticipate. Food colours are added to food or drink to modify the hue to make it more palatable. Natural food colours, synthetic food colours, and mixed food colours are the three food colours. Food colours are employed in commercial food manufacturing and home cooking to persuade consumers to buy a product based on its visual appeal. It improves the product’s taste, texture, and appearance while preserving its flavour and freshness. Any dye, pigment, or chemical that gives Colour when added to food and drink is a food colouring or colour additive. They are available in liquids, powders, gels, and pastes. Food colouring is used in both commercial and household food manufacturing. Food colourants are also utilized in cosmetics, medicines, home craft projects, and medical gadgets, among other non-food, uses natural food colours, artificial food colours and contemporary trends are discussed in this article.
The global market for Natural Food Color Ingredients was valued at USD 4864.9 million in 2019. The market will be valued at USD 5481.5 million by the end of 2026, with a CAGR of 1.7 % from 2021 to 2026. In 2019, India’s natural food colours industry was expected to be worth USD 74.09 million. It is predicted to reach USD 92.96 million by 2027, with a CAGR of 3.90 % across the area from 2020 to 2027. It is attributable to the expanding population and increased consumer awareness of health, expected to increase the industry. As people become increasingly aware of the detrimental health effects of synthetic food colours, demand for natural food colours is growing. Artificial food colours enhance the appeal of food. Brightly coloured meals pique the curiosity of consumers, particularly youngsters. Children who are fed processed food-flavoured eatables are more likely to develop attention deficit hyperactivity disorder. These behavioural changes are more common in youngsters who consume higher levels of artificial food colours.
Traditional raw and processed food colourants have been derived from natural pigments found in wild plants. Food and beverage nutrition experts suggest natural plant colours are healthy and add to the overall sensory attribute of the food. Figure 1 shows how several typical pigments compare in terms of colour and chemical structure.
Figure 1. Colour and chemical structure compare four typical natural pigments: anthocyanins, betalains, carotenoids, and phycocyanins.
Table 1: Plant Natural Color
Betalains are nitrogen-containing, water-soluble plant pigments found in most Caryophyllales plants. Betalains may be found in various plant components, including flowers, leaves, stems, and bracts. Violet betacyanins and yellow betaxanthins are the two types of betaxanthins. The pH range 5–6 is ideal for optimum betalain stability. When betanin solutions are stored in a low-oxygen environment, pigment degradation is minimized when stored in an air environment. Because the effects of light exposure are minimal in anaerobic settings, betalain light-driven degradation is oxygen dependant. Temperature is the most critical element influencing betalain stability during food preparation and storage. Table 2 shows some examples of plants that contain betalains.
Table 2: Plants containing Betalains
Chlorophylls are oil-soluble pigments that are responsible for plants’ distinctive green hue. Porphyrins or tetrapyroles chelated with a central magnesium atom make up the structure of chlorophylls. Heat, light, oxygen, acids, and enzymes are all very sensitive to chlorophyll, causing rapid breakdown and colour change. They thrive in alkaline pH ranges of 7-9. In an acidic pH, it becomes unstable. When a plant’s cell membrane is exposed to light or heat, it degenerates, producing acids that lower the pH. The primary cause of the chlorophyll colour change from green to olive-brown is acids and Mg-dechelatase, an enzyme present in algae and plants. These alterations are caused by the loss of a central magnesium atom in the chlorophyll structure, replaced by hydrogen ions, resulting in the transition of native chlorophylls into pheophytin, an olive-brown kind. Other enzymes that degrade chlorophyll and induce colour change include chlorophyllase and oxidative enzymes, including lipoxygenase, chlorophyll oxidase, and peroxidase. The plant-based beverage market requires this pigment to provide Colour and nutrition to many types of drinks.
Plant pigments having 40 carbon atoms are known as carotenoids. Carotenoids are yellow-orange-red pigments present in all higher plants. Carotenoids are divided into two types: carotenes, which contain only carbon and hydrogen, and xanthophylls, which include carbon, hydrogen, and oxygen. Because carotenoids may be converted into retinol in the body, they contain provitamin A action. It is more stable between the pH ranges of 4.0 and 6.0. Carotenoids are degraded mostly by oxidation and isomerization events, which result in a reduction in the redness and yellowness of plant pigments.
Table 3: Plant sources of carotenoids
Anthocyanins are water-soluble plant pigments. Many fruits and vegetables have blue, purple, red, and orange colours because of them. The quantity and location of hydroxyl and methoxy groups on the basic anthocyanidin skeleton determine the variety of anthocyanins. If hydroxyl groups predominate, the Colour will take on a bluish hue; if methoxyl groups predominate, the Colour will become redder. Anthocyanin colour stability is influenced by various factors, including pH, temperature, light, co-pigments, enzymes, oxygen, and sugars. The crimson flavylium cation is the single predominating equilibrium species in high acidity environments. As the flavylium cation is hydrated to the colourless carbinol form by nucleophilic attack of water, increasing the pH reduces the flavylium cation’s colour intensity and concentration. When the pH rises even higher, the carbinol form gives way to the colourless chalcone via ring-opening. Food and beverage development use Anthocyanins to a considerable extent due to its neutral chemical composition and excellent Colour it provides to the food.
It’s vital to remember that a single colouring agent may not provide the intended result; the background colour and nearby coloured substances significantly impact the colour appearance. Product designs that need blue or green limit the colour palette to just approved colours. Carmine can produce a bluish-purple, but it cannot make a pure blue. Compared to the brilliant hue created by the FD&C-yellow, annatto or turmeric has a cheese hue or an eggy tone. Nowadays, fluorescent colours are also essential in the food industry as consumers favour foods to glow under conditions. Turmeric is a very fluorescent spice that is often used in cooking. The physical and chemical qualities of a food product usually limit the colourant options. A list of available shades for food-grade bio-colourant is presented in Table 6.
Table 6. A wide range of food-grade biocolorants
Table 1 compares the extracted Colour’s physicochemical parameters with commercial brown Colour available on the local market. Although the total solid of commercial Colour was higher than that of tea extracted Colour, there was no significant difference in density. Commercial Colour has nearly seven times the amount of tea extracted in full Colour but no tannin or antioxidant properties. As a result, replacing the tea extracted Colour in food and colouring can provide health benefits to consumers. Permitted food colours include natural plant extracts in many forms.
The carotenoid lipid extracts derived from the tangerine epicarp might be used as a natural colouring ingredient in bakery items such as cakes and bread, thereby reducing the need for tartrazine.
The calyx of Hibiscus sabdariffa is high in cyanidin/delphinidin-based anthocyanins. In 1 g of the dried calyx, up to 23.83 2.44 mg of the desired anthocyanins may be measured. The most effective procedure, UAE, yielded 51.76 3.70 mg anthocyanins/g extract.
The wild blue colourant phycocyanin is isolated from the liquid biomass of Arthrospira platensis, blue-green algae known as spirulina. Phycocyanin can be extracted from biomass in 3 hours at room temperature using just phosphate buffer (pH 7.5, 100 mM).

Gynaecologists is a specialist doctors that take care of women's health while paying basic attention to their reproductive system.
These doctors handle many conditions, including pregnancy and childbirth, menstruation and problems with fertility, hormone disorders, sexually transmitted infections, and much more.
Most women like to see a gynaecologist instead of a family doctor when it comes to general health problems, and from there may be referred to another specialist by the GYN.
As a gynaecologist, a minimum of 8 years of training is a prerequisite. The practitioner must be certified by an examining body like the Royal College of Obstetricians and Gynaecologists (RCOG) and registered by a professional organisation like the General Medical Council (GMC).
A gynaecologist handles everything related to the female reproductive organs of patients, whether they are well-defined women or not. The type of gynaecologist that focuses on pregnancy and childbirth is called an obstetrician.
To have a career in gynaecology, one must begin by receiving a doctor's training for four years. After that, get another four years of special training in obstetrics and gynaecology. Certification and registration come after the person must have passed an examination on concluding the 8 years of study.
For yearly checkup and whenever a woman experience symptoms like pain in the pelvis, vagina and vulvar or unusual uterine bleeding, visiting a private gynaecologist London is necessary.
Conditions commonly treated by gynaecologists:
UK gynaecologists do provide gynaecological and general healthcare services, including preventive care for women. They also diagnose and treat problems like acne, change in mood, pain in the lower back and headache.
As for preventive care, a gynaecologist may offer advice on lifestyle issues like weight loss and smoking discontinuity.
At any age, a girl or woman may get care from a gynaecologist. The recommendation is between the ages of 13 to 15 years.
Females can leverage the early relationship with a gynaecologist to ask questions related to their sexuality without feeling embarrassed. This budding relationship is beneficial as a girl or woman can easily call a gynaecologist if symptoms show up later in life.

During a consultation with a gynaecologist, the following should be borne in mind:
It is okay to have someone go with a patient to the GYN examination. They can be inside the room or outside the door – ask the gynaecologist.
As recommended, women are to see a gynaecologist at least one time each year for examination.
At this annual checkup, the following will happen:
A sample of blood or urine may be needed for the screening.
Visiting a sexual health clinic regularly will give a patient updated information on living healthy and lower health risks as they attain a certain age.
Other annual assessments include blood pressure monitoring, colonoscopy, immunisations, mammography, and advice on taking folic acid and calcium.
Gynaecologists certified by the RCOG have been trained to perform some tasks regarding diagnosis and surgery.
Diagnostic procedures:
Surgical procedures:
Gynaecologists may also take care of other surgical conditions like obstruction of the small bowel.
To become a qualified gynaecologist, it is mandatory to graduate from a recognised medical school. This implies they are highly trained medical doctors that have got a license to practice.
Gynaecologists that are fully qualified have achieved a minimum of 8 years of medical study and training. Having a career in gynaecology requires 4 years of studies in a medical school and another 4 years of a residency program in the field of obstetrics and gynaecology.
Covered in speciality training:
