Exploring Food Grade Silicone: What You Need to Know
With the development of society, people's awareness of environmental protection continues to increase. Food grade silicone has gradually appeared in people's lives and become an increasingly popular product material. However, most people still don't really know "What is food grade silicone?" In this comprehensive guide, we explore the world of food grade silicone and explain what it is, how it is made, its uses, benefits and precautions.
1. What is food grade silicone?
Food grade silicone is a type of silicone that meets strict safety standards and is approved for use in contact with food. Food grade silicone is specially formulated to be non-toxic and odorless, so harmful chemicals don't leach into your food. In addition, Food grade silicone is resistant to high temperatures and is suitable for use in ovens, microwaves, and refrigerators.
2. How is Food grade silicone made?
The manufacturing process of food grade silicone involves multiple steps. The first is to extract silicone from silica. The extracted silicon combines with oxygen to form silicone. Additives that meet food safety standards are then added to the high-purity silica gel. These additives enhance silicone properties, such as flexibility and heat resistance, without compromising safety. Finally, the silicone mixture is processed to create the desired product, often through methods such as extrusion or molding.
3. What is the difference between food grade silicone and ordinary silicone?
Safety Standards: Food grade silicone is formulated to meet strict food safety standards to ensure it is free of harmful chemicals and impurities. Regular silicone may not meet such stringent standards.
Toxicity: Food grade silicone is non-toxic and safe for contact with food and beverages. Regular silicone may contain additives and contaminants that may be harmful if ingested or come into contact with food.
Smell and Taste: Food grade silicone is tasteless and odorless, but regular silicone may have an odor.
Certifications: Food grade silicone products often come with certification labels such as FDA, BPA-free, and LFGB approved. Regular silicon may lack these certifications.
Purpose: Food grade silicone is specially designed for baby products and kitchen supplies. Common silicones are used in a variety of products, from automotive parts to industrial seals.
4. What is the use of food grade silicone?
Baking Supplies: Food grade silicone baking mats, molds and utensils are popular for their non-stick properties and even heat distribution.
Cookware: Silicone cookware like spatulas, oven mitts, and trivets are heat-resistant and easy to clean.
Food Storage: Silicone food storage containers are airtight and can safely store hot and cold foods.
Kitchen Utensils: Silicone ice trays, oven mitts, and potholders are durable and heat-resistant.
Medical and Dental Devices: Food grade silicone is also used in medical and dental applications such as dental impressions and prosthetics.
5. Advantages of using food grade silicone
Security: The most important benefit is security. Food grade silicone is free of toxins like BPA, phthalates, and lead, so harmful chemicals won't leach into your food or drinks.
Non-Stick Properties: Silicone's non-stick surface is ideal for baking and cooking, reducing the need for added fats and oils.
Durable: Food grade silicone products are durable and wear-resistant, ensuring a longer service life compared to other materials.
Easy to clean: Silicone is naturally non-porous, easy to clean, and resistant to stains and odors.
Heat Resistant: Food grade silicone can withstand extreme temperatures from sub-freezing to high temperatures. Oven, microwave and refrigerator safe.
6. Precautions when using Food grade silicone
Temperature Limitations: Please be aware of the temperature limits specified on some food grade silicone products. Most products can withstand a wide range of temperatures, but exceeding these limits may cause damage.
Cleaning: Follow the silicone product manufacturer's cleaning instructions. Most can be cleaned with warm soapy water and dishwasher safe.
