Rose flower hydrosol as well as extraction method and application thereof

The invention provides rose flower hydrosol as well as an extraction method and application thereof. The method comprises the following steps: (1) carrying out protein removal: carrying out protein removal treatment on rose flower powder; (2) extracting: adding an extraction solvent into a protein-removed rose flower sample and adding a mixture into a reaction kettle; extracting to obtain the roseflower hydrosol. The extraction method provided by the invention has a simple technology; high-pressure hydrothermal extraction, protein removal and de-coloring treatment are combined, so that the content of water-soluble polysaccharides in the rose flower hydrosol and the transparency of the rose flower hydrosol are remarkably improved. 本发明提供了种玫瑰花水及其提取方法和应用，所述方法包括以下步骤：(1)脱蛋白：将玫瑰花粉末进行脱蛋白处理；(2)提取：向脱蛋白的玫瑰花样品中加入提取溶剂，投入反应釜，提取得到所述玫瑰花水。本发明的提取方法工艺简单，将高压水热浸提、脱蛋白和脱色处理相结合，显著提高了玫瑰花水中水溶性多糖含量和透明度。
