Extraction, Functional Properties and Food Applications of Rapeseed Meal Protein Isolates

As a by-product of rapeseed oil extraction, rapeseed meal is rich in protein and balanced in amino acid composition, which is a high-quality plant protein resource, however, it is commonly used for animal feed resulted in a lower economic benefit. Rapeseed protein extracted from rapeseed meal has been documented in excellent functional properties including emulsifying properties, gelling ability and so on. Its biological activities such as antihypertensive activity and antioxidant properties are also reported. At present, rapeseed protein has generally recognized as safe status and approved for food use in the European Union and FDA. In the current article, the different methods to extract rapeseed protein from rapeseed meal, the functional properties and the application statue in food industry are reviewed to provide theoretical basis and technical support for the further development and rational application of rapeseed meal protein.
