Novel sources of proteins have gained much attention in the recent years due to the increasing global demand for protein and the growing market for vegan products. Plants, algae, yeast and by-products from the food industry such as oil meals are promising sources of novel proteins. To demonstrate their capacity to replace conventional food ingredients, producers must be able measure objectively the functionality of their products.
Functional properties of proteins are very diverse in nature and strongly depend on the conditions of the test. Assessing protein functionality and comparing protein from different sources is therefore challenging. This presentation reviews the different methods available to measure protein functionality (emulsifying, foaming, gelling, water-holding…) and how factors such as pH, temperature or concentration may affect each test. Proteins from novel and conventional sources will be presented as illustrations.
1) What are the different aspects of protein functionality?
2) Which tools can be used to measure the functional properties of proteins?
3) Which parameters affect the functional properties of proteins?
