E904 food additive takes center stage in this engaging exploration, unveiling a world of culinary science and regulatory considerations. As we delve into its properties, applications, and safety profile, a clear understanding of this ubiquitous ingredient emerges.
This food additive, also known as shellac, is a natural resin derived from the secretions of the lac insect. It has been used for centuries in various industries, including food production, where it serves as a glazing agent, stabilizer, and anticaking agent.
Food Additive Classification
E904 falls under the category of food additives known as glazing agents. Glazing agents are substances that are applied to the surface of food to provide a shiny or glossy appearance. They can also help to protect the food from moisture loss and oxidation.
Specific Function of E904
E904, specifically, is a glazing agent that is derived from a type of seaweed called agar-agar. It is commonly used in the production of candies, baked goods, and other confectionery products. E904 helps to give these products a smooth, glossy finish and prevents them from becoming sticky or dry.
Chemical Composition and Properties
E904, also known as shellac, is a natural resin derived from the secretions of the female lac insect ( Kerria lacca). It is composed of a complex mixture of organic compounds, including polyhydroxy fatty acids, triterpenoids, and esters.
Chemical Name and Molecular Formula
The chemical name of shellac is not well-defined due to its complex composition. However, it is primarily composed of aleuritic acid, a polyhydroxy fatty acid with the molecular formula C 36H 68O 10.
Physical and Chemical Properties
Shellac is a hard, brittle resin with a glassy appearance. It is insoluble in water but soluble in alcohol, ether, and alkaline solutions. The melting point of shellac ranges from 75-85°C (167-185°F).
Shellac is relatively stable and inert but can undergo degradation over time, especially in the presence of light, heat, and moisture. It is also susceptible to oxidation, which can cause it to become darker in color and more brittle.
Production and Manufacturing: E904 Food Additive
E904 is produced through a chemical process that involves the reaction of several raw materials. These materials include:
- Sodium hydroxide
- Phosphoric acid
- Hydrogen peroxide
The production process begins with the mixing of sodium hydroxide and phosphoric acid to form sodium phosphate. This is then reacted with hydrogen peroxide to produce e904.
Chemical Reactions
The chemical reactions involved in the production of e904 are as follows:
NaOH + H3PO 4→ Na 3PO 4+ H 2O
Na3PO 4+ H 2O 2→ Na 4P 2O 7+ H 2O
Applications in Food Industry
E904 is a versatile food additive used extensively in the food industry. Its unique properties make it suitable for a wide range of food products, where it serves various functions and provides specific benefits.
The primary application of e904 is as a glazing agent. It imparts a glossy, protective coating to food surfaces, enhancing their appearance and extending their shelf life. E904 also acts as a stabilizer, preventing the separation of ingredients and ensuring a uniform texture.
Furthermore, it can enhance the flavor and aroma of certain foods, contributing to their overall sensory appeal.
Types of Food Products Using E904
- Confectionery: E904 is commonly used in the production of candies, chocolates, and gummies, providing a shiny glaze and preventing sugar crystallization.
- Baked Goods: It is added to pastries, cakes, and bread to improve their appearance, prevent moisture loss, and enhance their texture.
- Dairy Products: E904 is employed in the production of cheese and yogurt to stabilize their texture and prevent whey separation.
li>Fruits and Vegetables: It is used as a coating agent for fresh produce, extending their shelf life and maintaining their firmness.
Safety and Regulations
The safety of e904 as a food additive has been extensively evaluated by regulatory authorities worldwide, including the European Food Safety Authority (EFSA), the Joint FAO/WHO Expert Committee on Food Additives (JECFA), and the United States Food and Drug Administration (FDA).
Based on these evaluations, e904 is generally recognized as safe (GRAS) for use in food. The acceptable daily intake (ADI) for e904 has been established by JECFA at 10 mg/kg of body weight per day.
Potential Health Concerns
While e904 is generally considered safe, some potential health concerns have been raised regarding its consumption.
- Allergic reactions:E904 can cause allergic reactions in some individuals, particularly those with allergies to latex or certain fruits.
- Gastrointestinal issues:High doses of e904 may cause gastrointestinal symptoms such as nausea, vomiting, and diarrhea.
Restrictions and Regulations
Due to these potential health concerns, the use of e904 is restricted in some countries and for certain food products.
- EU regulations:In the European Union, e904 is approved for use in a wide range of food products, but with specific limits on its concentration.
- US regulations:In the United States, e904 is generally recognized as safe (GRAS) for use in food, but it is not permitted in infant formula.
Overall, e904 is considered a safe food additive when used within the established guidelines and regulations.
Alternatives to E904
While E904 is widely used as a food additive, there are several potential alternatives that can be used to achieve similar effects in food products. These alternatives offer advantages and disadvantages that should be considered when selecting the most appropriate option for a specific application.
