Study Notes
Control of Browning in Food
- Effective prevention of browning involves minimizing oxygen contact with food substrates.
- Use of sugar syrup creates a barrier to oxygen when covering foods.
- Film wraps with low oxygen permeability can also reduce contact between food and oxygen.
- Commercially prepared citric acid or ascorbic acid can be applied to cut fruit surfaces as a control method.
- Lemon juice mixed in a 3:1 ratio with water is a recommended treatment for fruit surfaces.
- This lemon juice application promotes oxidation of vitamin C instead of food pigments.
- Acidic pH from the lemon juice helps inhibit enzymatic reactions that lead to browning.
