Abstract

The invention belongs to the technical field of food processing and safety, and in particular relates to a rose residue modified dietary fiber composite gel and a preparation method thereof. The composite gel contains rose dregs modified dietary fiber and gelatin, the content of the rose dregs modified dietary fiber is 0.1-2%, and the content of the gelatin is 5-10%. The invention creatively uses rose dregs as a source of dietary fiber, and after modification, it is used to prepare a composite gel, which has suitable hardness, elasticity and taste, and can be used as a raw material for food with certain processing strength.

Description

Technical field: [0001] The invention belongs to the technical field of food processing and safety, and in particular relates to a rose residue modified dietary fiber composite gel and a preparation method thereof. Background technique: [0002] Roses are mainly used to extract rose essential oil in industrial production, and the low extraction rate (0.25‰-0.3‰) results in a high waste situation. At present, the deep processing of roses is still very limited. Except for a part of the flower dregs after extracting essential oils, they are naturally air-dried and used as fuel, and most of them are simply treated as waste. It not only harms the environment, but also causes a waste of resources. Therefore, the reuse of flower residue after essential oil extraction has become an innovative direction in rose research. [0003] Through the research of the present invention, it is found that the dietary fiber content in the rose dregs is rich, but the current research on the rose ...
