What Are Preservatives?
Preservatives are substances added to food products to prevent or delay spoilage caused by microorganisms such as bacteria, molds, and yeasts. They extend the shelf life of food by inhibiting microbial growth and maintaining its quality.
Types of Preservatives
There are various types of preservatives used in food products, including:
- Chemical preservatives (e.g., sodium benzoate, potassium sorbate)
- Natural preservatives (e.g., vinegar, salt, sugar)
- Biological preservatives (e.g., lactic acid bacteria)
Preservatives in Corn Tortillas
Traditional corn tortillas, made with only masa harina (corn flour), water, and lime, do not contain any added preservatives. However, commercially produced corn tortillas may contain preservatives to extend their shelf life.
Common Preservatives Used in Corn Tortillas
- Sodium benzoate
- Potassium sorbate
- Calcium propionate
Why Are Preservatives Added to Corn Tortillas?
Commercial corn tortilla manufacturers add preservatives to:
- Extend shelf life and reduce waste
