Colors play a vital role in our lives—from the visual appeal of foods to industrial and aesthetic applications in various products. One of the most sensitive areas in which color is used is the food and pharmaceutical industries. Edible and non edible colors not only enhance the appearance of products but can also directly impact human health. Understanding the differences, chemical compositions, and safety levels of these colors is essential for both consumers and manufacturers. Key factors in ensuring safety include knowing the chemical makeup, the source of the color, legal approvals, and purchasing from reputable suppliers. In this article, we will examine this subject in detail.

What Is Edible Color?

Food colors are substances used to color food, beverages, medicine, or other edible products. These colors are either naturally derived or synthetic. Their purpose is to increase visual appeal or compensate for color loss during production or storage.

Types of Edible Colors

1. Natural Food Colors

These are obtained from natural sources like plants, fruits, vegetables, and even certain insects. Examples include:

• Chlorophyll (green color from plants)
• Carotenoids (yellow to orange from carrots, peppers, etc.)
• Anthocyanins (red to blue from berries)
• Cochineal carmine (red from a type of insect)

2. Synthetic Food Colors

Produced in laboratories using chemical compounds. These usually have more stability and stronger colors. Examples include:

• Tartrazine (E102) – Yellow
• Azorubine (E122) – Red
• Brilliant Blue FCF (E133) – Blue

What Is Non-Edible Color?

Non-edible colors are substances intended for use outside the food chain. They may be used in industries such as textiles, paints, packaging, cosmetics, and cleaning products. These colors are generally not safe for human consumption and may cause serious health issues if ingested.

Differences Between Edible and Non Edible Colors

Why Is This Difference Important?

Using non-edible colors in food can lead to:

• Poisoning
• Severe allergic reactions
• Liver and kidney damage
• Increased risk of cancer

How to Identify Edible Colors?

1. Label includes an E-code (e.g. E110, E160)
2. Approved by the Food and Drug Administration
3. Purchased from reputable suppliers
4. Clear chemical and physical information on packaging

Chemical Composition and Safety Effects

In Edible Colors:
Organizations like the FDA (U.S. Food & Drug Administration) and EFSA (European Food Safety Authority) evaluate the chemical compounds in food colors and approve only those deemed safe. Each color has an Acceptable Daily Intake (ADI).

Example:

• Tartrazine is synthetic but considered safe within allowed limits. However, some individuals may experience allergies or sensitivity.

In Non-Edible Colors:
Many contain heavy metals (like lead, chromium, arsenic) or toxic aromatic compounds. Contact with food can cause cancer, neurological issues, or liver problems.

Dangers of Misusing Non-Edible Colors

In some cases—especially in unregulated markets—non-edible colors are wrongly or fraudulently used in food production. This can lead to:

• Acute or chronic poisoning
• Severe allergic reactions
• Growth disorders in children
• Increased cancer risk

These risks often arise from lack of regulation, ignorance, or attempts to cut costs.

How to Distinguish Between Edible and Non Edible Colors

1. Accurate labeling: Authorized products usually have E-codes (e.g., E133)
2. Purchase from trusted sources: Well-known chemical suppliers or specialty stores
3. Health certification: Health permit number or FDA approval on packaging
4. Quality control lab testing: Recommended for industrial applications

Uses of Edible Colors

Edible colors are used in many food, pharmaceutical, and cosmetic products to enhance appearance, replace natural color lost during processing, or differentiate products.

1. Food Industry

Used for visual appeal, stimulating appetite, and replacing lost color.

• Beverages: soft drinks, juices, syrups
• Sweets & baked goods: creams, jellies, icing, candies
• Dairy: ice cream, fruit yogurt, flavored cheese
• Snacks & processed foods: chips, sausages, cold cuts
• Preserves & pickles: colored olives, processed pickles

2. Pharmaceutical Industry

Used for:

• Tablets and capsules (different colors for different doses)
• Children’s syrups (flavor and color appeal)
• Vitamins and supplements

3. Edible Cosmetics

Products that may be unintentionally ingested must use food-safe colors:

• Lipstick
• Toothpaste
• Oral sprays

4. Children’s Products

• Gum, jelly candies, colorful lollipops
• Cake decorating colors for birthdays
• Chewable supplements

5. Special Use (Home or Educational)

• Coloring cakes and desserts at home
• Safe colors for science experiments in schools

Safety Note

Although approved and safe, food colors must:

• Be used within permitted limits (as per ADI)
• Excessive consumption of some synthetic colors may cause sensitivity or hyperactivity in children (e.g., Tartrazine)

Standards and Approvals for Food Colors

In Iran, the Food and Drug Organization under the Ministry of Health is responsible for monitoring the safety of food colors. Only those on its approved list can be used in the food industry. Imported colors must also have proper licenses and declared sources.

Role of Reputable Suppliers in Ensuring Safety

Trusted suppliers play a critical role in consumer safety by providing genuine chemical materials and colors. Companies that offer food-grade colors meeting international standards from reputable brands help reduce health risks.

Example:
Suppliers like Aref chemical, by offering original chemicals with standard packaging, detailed specifications, and expert consultation, help ensure the final product’s quality and safety.

Where Did the Idea of Food Coloring Come From?

The concept dates back centuries, rooted in the human desire to beautify food, stimulate appetite, and compensate for color loss during processing.

Historically, people used natural sources like beets (red), turmeric (yellow), spinach (green), and carrots (orange) for food coloring. These colors often had therapeutic properties as well.

With the advancement of chemistry, the first synthetic food colors were developed in the 19th century. The first synthetic dye (e.g., Tartrazine) was derived from coal. Initially, colors were used without regulation and were sometimes toxic.

Due to poisonings from unregulated dyes, governments started implementing food safety laws. Today, food colors must be approved and standardized by organizations like the FDA (U.S.), EFSA (Europe), and Iran’s Ministry of Health.

The idea of food coloring was born from a combination of aesthetic need, food differentiation, and chemical science. What began as a simple idea has now become a vast, scientifically regulated industry focused on enhancing the attractiveness and safety of food.

Conclusion

Using colors in food and other products, if done correctly and in accordance with standards, not only poses no problem but also improves the consumer experience. However, distinguishing between edible and non edible colors is crucial and must be strictly observed. With informed choices, we can enjoy the beauty of colors without compromising our health or that of others.

How is wood glue made?

Wood glue is mainly made from polymeric materials and chemical compounds designed to provide the desired adhesion. The steps in making wood glue can be summarized as follows:

Selection of raw materials

– Polymers: Usually, a mixture of polyvinyl acetate (PVA) is used, which is a type of synthetic polymer and is considered one of the main ingredients of wood glue.

– Additives: Some other materials, such as dyes, antiseptics, and stabilizers, are added to the main composition to improve the properties of the glue.

Production process

– Mixing: The raw materials are carefully combined. This step involves mixing the main polymers with additives and solvents.

– Polymerization: In some cases, the raw materials undergo a polymerization process to form larger molecules that give them greater adhesive properties.

Quality Control

– Testing and Evaluation: After production, the adhesives undergo various tests to ensure quality, stability, and adhesion properties.

Packaging

– The ready-to-use adhesive is released into the market in various packaging, including bottles or cans.

This process helps produce high-quality, high-performance wood adhesive
