Milk thistle (Silybum marianum L. Gaertner) oilseed cake flour functional, nutritional and antioxidant characteristics as effect of cultivar and preparation process

Original language description

Oilseed cakes left after the oil extraction are mainly used as feed or compost amendment, but this is a waste of potential for the production of protein-rich flour. Similarly, milk thistle (Silybum marianum L. Gaertner) is mainly used as an oilseed crop and pharmaceutical herb, but the seeds are also rich in protein. Here, milk thistle oilseed cakes of Tevasil and Tevadian cultivars were defatted and fractionated by sieving in flours below and above 250 μm and were used for the preparation of protein extract and concentrate using alkali extraction and acid precipitation. The obtained products were analysed for their composition, nutritional and functional characteristics. The highest protein content was found in defatted flours sieved below 250 μm, reaching 38.76 and 44.92% of dry matter (DM) for Tevasil and Tevadian, respectively. In the fraction of the flour above 250 μm, there was an accumulation of fiber and substances with antioxidant potential, including silymarin complex. In the above 250 μm fraction, antioxidant activity (using ABTS radical) reached 88.3 and 88.5 mg AAE g&lt;sup&gt;−1&lt;/sup&gt;, and silymarin content was 66.12 and 68.82 mg g&lt;sup&gt;−1&lt;/sup&gt; of DM for Tevasil and Tevadian, respectively. A final product with a protein of up to 96% and protein solubility of up to 89% was obtained similarly for both cultivars, combining alkali extraction and acid precipitation.
