When it comes to food coloring, many people may be skeptical about the safety of synthetic food coloring. Fortunately, natural food coloring has benefits for both health and the environment. In the following time, we will explore natural food coloring, including how they are made and different types of natural food coloring. We will also delve into various applications of natural food coloring and provide some tips for effectively using natural food coloring.

1.  What are natural food colorings?

Natural food colorings pertain to any color substance procured from natural sources, such as plants, fruits, vegetables, and seasonings, that may color hue to foods and beverages. We'll explore the different forms of natural food coloring and the importance of using them in our food.

1.1 Forms of natural food coloring

Different types of natural food coloring are available in the market based on the source and extraction method. Some common types are:

1.Liquid: Liquid food coloring is created by extracting color pigments from natural sources like fruits and vegetables and mixing them with a liquid base such as glycerin or water. It creates a versatile and easy-to-use coloring that can be added to various foods and beverages.

2. Powder: Natural food coloring powders are made by grinding dried fruits, vegetables, and other natural sources to create fine powders that can be added to recipes for color. They are ideal for recipes that require dry ingredients or where adding a liquid would affect the dish's texture.

3. Gel: Combining natural color pigments with gelling agents like agar or pectin creates gel-based natural colorings. These are perfect for pastry and confectionery applications like decorating cupcakes and cakes.

2.  Types of Natural Food Coloring

2.1 Plant-based colorants

Plant-based colorants can provide a diverse range of vibrant hues. These colorants come from different parts of plants, such as leaves, flowers, stems, and roots, and offer a sustainable and natural option for coloring food.

  • Beetroot

Beetroot is one of the most well-known plant-based colorants, known for its deep red color. It can present a deep red color because it contains a group of water-soluble pigments called betalains. The concentration of betalains determines the intensity of the red coloring dye, ranging from a deep red with a high concentration to a light pink with a low concentration. Various food products, including cakes, desserts, and beverages, commonly use this versatile colorant.

  • Turmeric

The turmeric plant's roots yield turmeric, which contains the active ingredient curcumin and offers a bright yellow color. Savory dishes such as curry, rice, and pasta commonly use this colorant. However, the stability of curcumin can be affected by factors such as pH and temperature. High or low pH levels in food products can cause the color to change or fade over time, and exposure to heat can also impact its stability.

  • Spinach

Spinach is a green coloring agent extracted from the leaves of the spinach plant. The pigment that causes spinach to be green is called chlorophyll. Chlorophyll is a natural pigment in most green plants responsible for photosynthesis. It can color foods such as pasta, baked goods, and beverages.

  • Saffron

Saffron is a natural food coloring that comes from the stigma of saffron. The active ingredient in saffron that gives it its color is called saffronin. Saffronin is a water-soluble carotenoid pigment responsible for the bright orange-red color of saffron. Saffron adds color and flavor to various foods, such as rice, desserts, and sauces.

  • Red cabbage

Red cabbage is a natural food coloring extracted from the leaves of the red cabbage plant. The pigment responsible for the purple-red color of red cabbage is called anthocyanin. Anthocyanin is a water-soluble pigment accountable for the purple-red color of many fruits and vegetables. Red cabbage can be boiled to create a blue color, which can be used in foods such as candies, icings, and beverages.

2.2 Fruit and vegetable juices

We can derive natural food coloring by extracting fruit and vegetable juices from various plants, and they provide a range of natural colors from red and orange to green and purple.

  • Carrots

Carrots are a commonly used natural food coloring agent, rich in carotenoids that give them an orange hue. Food manufacturers can utilize them in various forms to add natural colors. For example, they can add carrot juice to beverages and smoothies to give them an orange hue. Carrot powder can be used in baking, such as cakes and muffins, while shredded or pureed carrots can add color and nutrition to dishes like sauces and soups.

  • Blueberries

Blueberries are also a popular source of natural food coloring due to anthocyanin, a water-soluble pigment that provides blue, purple, and red hues. Blueberries can take on many forms, and blueberry juice or puree can add a blue or purple color to beverages, smoothies, and dairy products. The freeze-dried blueberry powder can provide a natural blue or purple hue in baked goods such as muffins and cakes.

  • Pomegranate

Pomegranate is a delicious and healthy fruit that is a natural food coloring. Its deep red color suits foods such as sauces, marinades, desserts, and beverages.

2.3 Spices and herbs

  • Paprika

Paprika is a spice made from ground, dried peppers of the Capsicum annuum species. It serves as a seasoning and coloring agent in various dishes, including stews, soups, and grilled meats.

  • Annatto

Annatto, also known as achiote, adds a slightly sweet and peppery flavor to food, along with a yellow-to-orange hue, and comes from the seeds of the achiote tree. Commonly used to season meats, fish, and rice dishes.

  • Parsley

Parsley is a widely used herb in many cuisines worldwide and is also valued for its bright green color, making it a popular natural food coloring. You can use parsley to add color to dishes like salads, soups, and sauces and to garnish plates.

  • Basil

Basil, a versatile ingredient in many dishes, provides vibrant green color to food products, often used in sauces, pesto, and salads. Its unique flavor and aroma make it a popular herb in cooking, doubling as a natural food coloring.

3.  How is natural food coloring made?

3.1 Extracting color from plant-based materials

Natural food coloring can be made using various methods depending on the source material. Here are two standard methods of extracting color from plant-based materials:

  1. Extraction Methods

This method involves extracting the pigments from the plant source using solvents such as ethanol or water. The plant material is first dried and then ground into a fine powder. The powder is then mixed with the solvent and left to soak for some time. The resulting mixture is then filtered to remove any solid particles, and the remaining liquid is evaporated to leave behind a concentrated color extract.

2. Processing Methods

Some natural colorants can be obtained through simple processing methods like boiling or crushing. For example, beet juice can be obtained by boiling beets and straining the liquid. Turmeric can be ground into a powder and used as a spice or boiled to extract the pigment.

Natural food coloring can be made using various methods depending on the source material. Here are two common methods of extracting color from plant-based materials:

3.2 Extracting color from Fruit and vegetable juices

We extract color from fruit and vegetable juices using various methods, including pressing, enzymatic extraction, solvent extraction, and freeze-drying.

  1. Pressing

This involves pressing the fruits or vegetables to extract the juice containing natural color pigments. The juice can then be used directly as a natural coloring.

  • Enzymatic extraction

Enzymatic extraction uses enzymes to break down cell walls, release the pigments, and then filter the juice to remove solids.

  • Solvent extraction

Solvent extraction uses a solvent such as ethanol or acetone to extract the pigments from the juice, followed by evaporation to leave behind the natural color concentrate.

  • Freeze-drying

Freeze-drying involves freezing the juice and sublimating the water to obtain a powder containing natural color pigments.

3.3 Extracting color from Spices and herbs

Spices and herbs provide a natural source for food coloring, with pigments extracted through maceration, steam distillation, and solvent extraction methods.

  • Maceration

Maceration involves soaking herbs or spices in a liquid like water, oil, or alcohol to release pigments. Turmeric, saffron, and paprika are commonly macerated to produce natural food dyes.

  • Steam distillation

Steam distillation entails passing steam through the herbs or spices to extract the pigments' essential oils. Basil, rosemary, and thyme are usually subjected to this method to create natural food coloring.

  • Solvent extraction

Solvent extraction dissolves the pigments from the herbs or spices using a solvent such as ethanol. The resulting solution can be further processed to isolate and purify the pigment. Annatto, which produces a yellow-orange pigment, is often subjected to this method for natural food coloring production.

Cooking enthusiasts use saffron to give yellow color to rice dishes, while paprika is used to add red color to sauces. In addition, chefs use spinach juice to produce green color in pasta.

5.  How to Use Natural Food Coloring?

Whether you want to add a pop of color to your baked goods or liven up your beverages, natural food coloring can be a great alternative to artificial dyes. However, incorporating natural food coloring into your recipes can be a bit different from using synthetic dyes. We will provide some tips on using natural food coloring based on our sales experience, as well as common questions our customers ask when purchasing products. This includes the dos and don'ts of using natural food coloring, as well as recommended usage amounts to help you get started.

5.1 Usage Tips

We've heard from some of our customers that natural food coloring can be more delicate and sensitive than the synthetic stuff. No need to worry, though! We have some tips and tricks we recommend keeping in mind as you start using natural food coloring.

  1. Start with small amounts: It's best to start with small amounts of natural food coloring and add more as needed. This way, you can avoid over-coloring your food and adjust the color to your liking.
  2. Mix with a liquid: Natural food coloring powders can sometimes be clumpy, so it's a good idea to mix them with a small amount of liquid before adding them to your recipe. It will help to evenly distribute the color and prevent clumps from forming.
  3. Use heat: Some natural food colorings may need to be heated to release their full-color potential. For example, beet powder may turn a brighter shade of red when heated in a recipe.
  4. Consider the flavor: Natural food colorings can sometimes affect the flavor of your recipe, so it's essential to consider this when adding them. For example, turmeric can add a slightly bitter taste to a recipe, while spirulina can have a seaweed-like flavor.
  5. Experiment: Don't be afraid to experiment with different natural food colorings and amounts to find the perfect shade for your recipe. It can be helpful to keep notes on how much you used and the result so that you can replicate it in the future.

5.2 Precautions for use

  • Don't use expired products

Check the expiration date on your natural food coloring, and don't use any products past their prime.

  • Don't use too much

Adding too much natural food coloring can result in a bitter or artificial taste, and it can also affect the texture of your recipe.

  • Don't use natural food coloring to cover up poor-quality ingredients

While natural food coloring can add a beautiful hue to your recipe, it shouldn't be used to cover up poor-quality or expired ingredients. Always use fresh, high-quality ingredients to ensure the best possible results.

5.3 Recommended usage levels

The recommended usage levels for natural food coloring vary depending on the specific product and the desired color intensity. However, as a general guideline, the following usage levels are recommended by the FDA for natural food colorants:

  1. Plant-based colorants: Typically used at 0.1-5% concentration, depending on the desired color intensity.
  2. Fruit and vegetable juices: Used at up to 10% concentration, depending on the juice and desired color intensity.
  3. Spices and herbs: Used at up to 0.5% concentration, depending on the spice or herb and desired color intensity.
