Biocompounds from rapeseed oil industry co‐stream as active ingredients for skin care applications
Tóm tắt
Despite the great number of substances produced by the skincare industry, very few of them seem to truly have an effect on the skin. Therefore, given the social implications surrounding physical appearance, the search for new bioactive compounds to prevent or attenuate skin ageing and enhance self‐image is a priority of current research. In this context, being rich in valuable compounds, such as proteins, phenolics, lipids and vitamins, this study is focused on the potential activity of rapeseed press cake hydrolysates to be used as raw materials for skincare applications.
In this study, the protein‐rich press residue from the rapeseed oil industry was converted enzymatically into short‐chain biologically active peptides using four protease products with varying substrate specificity – Alcalase 2.4L
All hydrolysates were biocompatible with skin fibroblasts after 24 h of exposure, while the non‐hydrolysed extract induced cell toxicity. Alcalase 2,4L
The enzymatic technology applied to the rapeseed oil industry costream results in the release of bioactive compounds suitable for skincare applications.
