What are Food Preservatives Used For?
Conservatives are chemicals added to food to extend its shelf life. They protect food products from deterioration caused by the presence of microorganisms and prevent the development of pathogens. Along with many other substances, such as dyes and stabilizers, they are part of a relatively long list of food additives that are intentionally included in food products. They are denoted by the symbol Conserva E and are specifically attributed to preservatives, ranging from E200 to E299.
Canned Meats and Meat Preservatives.
The more processed food we are dealing with, the longer the list of preservatives it contains. Highly processed foods include fast food, salted snacks, soft drinks, instant products, fruit and vegetable products, canned meat and fish, and ready meals. These are products that often taste intense in flavor and aroma, but all of their apparent benefits, including their endless shelf life, come from their food additives.
Where Are Hidden Preservatives Found?
Unfortunately, even when we generally eat healthy and avoid eating out-of-home meals, we may find that our refrigerator or kitchen cabinet is full of preservatives. People who have substituted margarine butter for health or taste reasons often enjoy a wide range of manufacturers offering mixtures, margarines with a new flavor, extra scent or special consistency, which are rich in sourbs (E 200) and potassium benzoic acid (E 212).
Semi-Natural Preservation Methods.
Almost every refrigerator contains meat and dairy products, which have been consumed in Polish culture for generations. However, not every consumer is aware that today's products often contain a long list of enhancers that prolong their shelf life. This applies especially to sausage and melted sausages rich in sorbic acid (E200), but also to many sausages and sausages high in nitrogen (E 249-E 252).
Chemical-Free Alternatives.
Fortunately, we're not condemned to have everything we put in our mouths accumulating chemical deposits. There are food products that are completely devoid of preservatives. These include, among other things, unprocessed foods, such as fruits, vegetables, grains, oils, butter, milk and naturally fermented dairy products, mineral water, coffee and tea leaves. These are products which are legally protected against the use of preservative substances, but that's not their only advantage.
Are Preservatives Safe or Hazardous?
Of course, all the preservatives that we can find in the composition of our food products are allowed to be used, and their quantities are considered safe. However, in the light of the available evidence, the quantities currently available are considered to be safe. The safety of food additives is monitored by the Scientific Committee on Food Safety (SCF) and the European Food Safety Authority (EFSA). So where do so many food additive antagonists come from, if they are safe substances? All the scientific studies that have been conducted have some limitations.
