The invention discloses a method for extracting fructose and fructose content from hawthorn, and relates to the field of fructose extraction. The method includes the following steps: raw material selection, pretreatment, hawthorn pressing, hawthorn juice cleaning, fructose crystallization and content detection. When selecting raw materials, choose fresh hawthorn that is plump and mildew-free; before the pressing process of hawthorn, the hawthorn is washed and sealed to prevent pollution; during pressing, the hawthorn is squeezed more thoroughly by pressing multiple times; In the process, there is a secondary carbonation, and the obtained hawthorn juice is clear juice, which improves the purity of the sugar juice, reduces the viscosity and color value, and provides high-quality raw material syrup for the crystallization process, and the obtained fructose crystal particles are relatively pure. The final content detection method has simple steps, uses less reagents, and is suitable for manual operation. |
