How to Choose the Right Food Enzyme for Your Process
Selecting the right food enzyme requires a clear understanding of the raw material and the intended reaction. Although many enzymes offer overlapping applications, each product has specific activity characteristics.
1. Identify the Target Substrate
First, identify the component you want to modify. Is it protein, starch, sugar, fat or fibre? This step helps narrow down the appropriate enzyme family.
- For protein hydrolysis, consider protease.
- For starch conversion, consider amylase or glucoamylase.
- For lactose breakdown, consider lactase.
- For pectin degradation, consider pectinase.
- For cellulose breakdown, consider cellulase.
- For sucrose conversion, consider invertase.
2. Check the pH of Your Process
Enzyme activity changes with pH. For example, acid protease works under acidic conditions, whereas neutral protease suits applications closer to neutral pH. Therefore, always match the enzyme's activity profile with the food matrix.
