Understanding the Causes of Food Spoilage
Food spoilage is a critical concern for the food industry because it reduces the quality, taste, appearance, and texture of food, making it unsuitable for consumption.
Food can spoil due to 3 main factors:
1️⃣ Physical changes
- Impact or compression that damages texture
- Temperature fluctuations, such as rapid cooling after heat or repeated freezing and thawing
- Improper storage causing sedimentation or separation
2️⃣ Chemical changes
- Oxidation of fats, resulting in rancid odors
- Enzymatic reactions that change color or taste, e.g., fruits turning brown
- Acid formation or fermentation from chemical reactions, e.g., fruit juices turning sour
3️⃣ Microbial changes
- Growth of bacteria, yeast, or molds on food surfaces
- Formation of slime or fermentation odors
- Contamination from hands, equipment, or unclean packaging
💡 In the food industry, Shelf-Life Extenders are commonly used to control these processes. They help inhibit microbial growth, reduce chemical reactions, and maintain food quality, flavor, and safety for longer periods.
In particular, pH adjusters help control the pH level of food, limiting microbial growth and keeping food quality intact for extended shelf life.
