E904 - Shellac

Shellac, also known as E904, is a natural resin secreted by the female lac bug. It is commonly used in various industries, including food and nutrition. In the context of nutrition, shellac is used as a food glaze and coating agent, providing a glossy finish to many products.

What is Shellac?

Shellac is derived from the excretion of the lac bug, which is native to India and Thailand. The female lac bug secretes a resinous substance to create a protective cocoon for her eggs. This resin is harvested and processed to produce shellac.

Uses in Food and Nutrition

Shellac is used in the food industry primarily as a glazing agent. It is commonly applied to fruits, vegetables, and confectionery products to enhance their appearance and prolong their shelf life. The glossy finish provided by shellac makes the products more visually appealing to consumers.

Benefits of Shellac in Food

Shellac offers several benefits when used in food and nutrition:

• Improved Appearance: Shellac gives a shiny and attractive appearance to food products, making them more visually appealing.
• Extended Shelf Life: The protective coating formed by shellac helps to extend the shelf life of fruits and vegetables by reducing moisture loss and preventing microbial growth.
• Preservation of Freshness: Shellac acts as a barrier against oxygen and other external factors, helping to preserve the freshness of the coated products.

Concerns and Considerations

While shellac is generally considered safe for consumption, there are a few considerations to keep in mind:

• Allergies: Some individuals may be allergic to shellac. It is important to read product labels and consult with a healthcare professional if you have any concerns.
• Vegetarian and Vegan Diets: Shellac is derived from an insect source, which may not align with vegetarian or vegan dietary preferences. If you follow these diets, it is advisable to check product labels for alternative coatings.
• Regulatory Approval: Shellac is approved for use as a food additive by regulatory authorities, including the Food and Drug Administration (FDA) in the United States and the European Food Safety Authority (EFSA) in Europe. However, it is always recommended to consume shellac-coated products in moderation as part of a balanced diet.
