Oleosomes are oil droplets abundant in oilseeds that can be extracted together with proteins for use in emulsion-like foods and can be used as natural, ready emulsions as alternatives to dairy and fat-based products. To make optimal use of the raw material, we look at simultaneous extraction of oleosomes and proteins from rapeseed. The combined approach of colloid milling and twin screw pressing resulted in a higher yield of oleosomes (70 % w/w) when compared to twin screw press alone (54 % w/w), which may be due to extensive cell wall disruption caused by colloid mill processing, as evidenced by SEM imaging. The protein yield remained constant irrespective of the degree of cell wall disruption (50 % w/w). In conclusion, combining the colloid mill and twin screw press is a straightforward way for the extraction of oleosome and proteins from rapeseeds for food application.

油质体是油籽中富含的油滴，可以与蛋白质一起提取用于乳状食品，并且可以用作天然乳状液，作为乳制品和脂肪产品的替代品。为了充分利用原材料，我们研究从油菜籽中同时提取油质体和蛋白质。与单独的双螺杆压榨机 (54% w/w) 相比，胶体磨和双螺杆压榨的组合方法产生了更高的油质体产量 (70% w/w)，这可能是由于胶体磨处理，由 SEM 成像证明。无论细胞壁破坏程度如何，蛋白质产量均保持恒定（50% w/w）。总之，将胶体磨和双螺杆压榨机结合起来是从油菜籽中提取油质体和蛋白质用于食品的直接方法。
