Types of E472 emulsifiers
There are several types of E472 emulsifiers, each of which plays a different role in the food industry.
- E472a Tdiglycerol Acetate: It is mainly used in some chewing gum applications to provide stickiness and help prevent stickiness. It is usually added to improve the food quality and shelf life.
- E472b Glycerol Mono and Diacetate: This particular emulsifier can be used in many areas, including but not limited to margarine, fried food and bakery products. It can help improve food texture, maintain moisture and prolong shelf life, and its anti-osmotic properties can help control the food's osmosis, which makes it prevent food from going soggy and make it more crisp.
- E472c Glycerol Acetate Butyrate: This specific emulsifier is usually added to ice cream and dairy products, such as cream cheese, cheese spreads, etc. It can improve the texture of the product and give a smoother mouthfeel. Apart from that, it can also withstand ice crystal growth and improve the stability of products. Additionally, it can increase the melting rate of fat in the mouth, making the taste of fat fuller. Cream and oral emulsifying agents can include cod liver oil and some other fish oil.
- E472d Polyglycerol Esters of Vinegar: This particular emulsifier is usually added to salad dressings, sauces, and condiments. It can help keep oil and vinegar from separating, improving product stability and emulsion quality. Besides, it can also be used in baked goods to improve dough strength and retain freshness.
- E472e Acetic Acid Esters of Monoglycerides: This particular emulsifier is widely used in baking and pastry products. It can delay staleness and enhance the shelf life of the product. It can also be used in frozen desserts to reduce the melting rate and improve melt quality.
Specifications and maintenance of E472 emulsifier
The specifications of emulsifier E472a may vary depending on the manufacturer and product formulation. Still, they generally include the appearance, content, acid value, saponification value, iodine value, surface tension, interfacial tension, emulsion stability, viscosity, and pH.
- Appearance: The emulsifier may appear as a pale yellow to light brown waxy solid or flakes with a slight odor.
- Content: The content of E472a emulsifier refers to the percentage of esterified fatty acids and glycerol in the product. The content may affect the emulsifying ability and stability.
- Acid value: The acid value of the emulsifier indicates the amount of free fatty acids in the product. A lower acid value can help reduce odor and improve product quality.
- Saponification value: The saponification value represents the number of fatty acids that are contained in the emulsifying agent. This value influences the dissolving capacity and emulsifying ability.
- Iodine value: The iodine value describes the degree of unsaturation of fatty acids in the emulsifier. This may influence its stability and emulsifying properties.
- Surface tension: Emulsifier E472 can reduce surface tension, enabling liquids to blend together more easily. Emulsifying agents that reduce surface tension are crucial for the formation of stable emulsions.
- Interfacial tension:E472 emulsifiers can reduce interfacial tension between the oil and water phases, making them mix together more readily. The formation of stable emulsions requires the reduction of interfacial tension by emulsifiers.
- Emulsion stability: E472 emulsifiers can stabilize oil-in-water (O/W) or water-in-oil (W/O) emulsions. Different types of E472 have different stabilizing effects on emulsions.
- Viscosity: The viscosity of E472 emulsifiers can vary depending on different products and temperatures. The viscosity affects the emulsifier's distribution and emulsifying capacity.
- pH: The pH of the emulsifier may affect its emulsifying property and stability. E472 might be acidic or neutral, depending on the specific type and formulation.
In general, the performance indicators of E472 emulsifiers include emulsifying ability, stability, anti-aging property, heat-resisting property, salt tolerance, and shelf life. These performance indicators make them widely applicable in the food industry, cosmetics, pharmaceutical industry, and other fields.
Cleaning the emulsifier is a very important step in assuring hygiene and safety and should adhere to the following maintenance steps:
- Get the proper supplies: Get the detergent or sanitizer approved for use in food equipment, and make sure it's suitable for the emulsifier model you have.
- Power off: Ensure that the emulsifier is powered off to prevent accidental operation or electric shock during the cleaning process.
- Disassemble parts: Following operational guidelines, properly disassemble the emulsifier's parts, including mixers, containers, etc. Ensure that parts that need to be cleaned are disassembled.
- Cleaning: Use warm water and suitable cleaning agents to clean the emulsifier's components. Use cleaning agents to clean essential parts of emulsifiers or tools. Use a soft brush or sponge to gently scrub the surface of the components, making sure to reach all the gaps, but avoid using abrasive agents to prevent damage to the surface.
- Wipe: After cleaning, use clean water to wash off the cleaning agents thoroughly, and use clean towels or rags to wipe the surfaces of parts of emulsifiers through which they come into contact with food.
- Disinfection: Use food-grade sanitizer to disinfect the parts of the emulsifier in contact with food. Follow the instructions, apply the sanitizer, and ensure proper sanitation during operations.
- Assembly: After cleaning and disinfection, assemble the parts of the emulsifier and make sure they're fastened securely. Ensure that the disassembled parts are in the right places.
- Wipe the outside: Wipe the surface of the emulsifier with a clean rag or towel to clean the stains and dirt on its surface. If necessary, use a suitable cleaner to clean the emulsifier's outer surface.
- Storage: Properly store the emulsifier and ensure that it is covered or sealed to prevent dust and dirt from contaminating it.
Scenarios
Food E472 emulsifiers have several applications across different food production industries.
- Bakery: Food E472 emulsifiers are used in the baking industry to improve bread volume, increase shelf life, enhance crumb texture, and prevent staleness. They are also used to simplify dough processing, improve dough elasticity and extensibility, and enhance the quality of baked goods like cakes, pastries, and croissants.
