What are the different types of preservatives?

There are a number of preservatives of food used by chefs and food manufacturers to prolong durability and improve the storage of cooked and raw foods. Many nature preservatives such as salt and sugar are often used to preserve canned fruit, processed meat and various types of canned or appalling vegetables. Nitrates and nitrites are common artificial preservatives found in many processed masses, including lunch and bacon, and are made of naturally occurring sodium chloride found in table salt. Antioxidants also play a role while maintaining fresh and processed foods, as well as their own home preservation methods such as freezing, pickling or appalling food. One of the most common preservatives is salt, suitable for many uses such as preserving meat, canned vegetables and fruits, as well as frozen dessert vegetables. Salt is one of the most popular preservatives used at home to protectraw meat, because salt helps to draw moisture from the meat through a process called osmosis. This is often called meat treatment and is one of the oldest known food protection methods.

Artificial preservatives called sodium nitrite and sodium nitrate are often used in the processed meat and are derivatives of natural sodium found in regular table salts. Sodium and nitrites nitrates are commonly found as preservatives in lunch, bacon and ham and sometimes found in processed minced beef. Sugar is also one of the common preservatives, often used to extend the durability of desserts and sweet foods such as canned fruit or candy. In many processed foods, natural sugar is sometimes replaced by corn syrup with a high fructose content to act as a cheaper sweetener and preservatives.

synthetic antioxidants such as ButylovAryic hydroxyanisol and butyl hydroxytoluene are added to some foods to prolong the durability of the fight against oxygen damage to the food. Most synthetic food preservatives contain some controversy about their health effects, but science remains unclear in terms of accurate effects that have small amounts on human health. Food protection methods such as freezing or drying are very popular for individuals preparing food at home. Canned and brittle foods with vinegar and salt are also excellent preservation methods used to prolong the durability of any raw or cooked food.
