Food Additives in China An Overview
SBR possesses a unique combination of properties that make it valuable in a variety of settings. One of the most significant characteristics is its excellent abrasion resistance, which extends the life of products made from it. Additionally, SBR demonstrates good aging stability, allowing it to maintain its properties over time, particularly when exposed to environmental conditions. It exhibits a moderate level of resistance to oil and chemicals, though it is not as resistant as certain other synthetic rubbers like nitrile rubber.
One of the primary functions of preservatives is to extend the shelf life of food by inhibiting the growth of bacteria, molds, and yeasts. Natural preservatives originate from various plant and animal sources, making them more appealing to health-oriented consumers. Common examples include salt, sugar, vinegar, alcohol, and certain herbs and spices.
Another notable application of E223 is in the bleaching of certain food products. In the case of potatoes or dried fruits, sodium metabisulfite acts to preserve the natural color and aesthetic appeal of the food. It is also employed in the production of certain processed foods, where visual presentation is paramount.
