Problems solved by technology

[0003] At present, there are various extraction methods, but the single extraction method has great limitations and low extraction rate. The single use of enzyme extraction takes a long time, and the single use of ultrasonic extraction consumes a lot of energy, which makes the recycling rate of orange peel resources low and increases the cost of plant dyes. The difficulty of industrial utilization

Abstract

The invention provides a method for extracting orange peel dye. The method comprises the following steps: crushing orange peel to 60-100 meshes; performing enzymolysis on an aqueous solution containing a complex enzyme to form an enzymolysis solution; performing ultrasonic treatment on the enzymolysis solution to obtain an ultrasonic extract solution; centrifuging the ultrasonic extract solution;performing spray drying to obtain the orange peel dye. According to the technical scheme, preparation and use processes are non-toxic and harmless, the dyed wool fiber product obtained finally is goodin dyeing effect, texture and handfeel of the wool fiber product are not damaged, and a novel fiber product with higher added value is formed.

Description

technical field [0001] The present invention relates to a kind of dye and its application, especially relates to a kind of orange peel dye and its preparation method and application. Background technique [0002] Tangerine peel is the mature peel of the Rutaceae plant orange and its cultivars. my country is one of the origin centers of citrus in the world, with an annual output of 15 million tons of oranges. With the acceleration of the industrialization of orange deep processing, orange peel is its main product. By-products are not rationally utilized, resulting in waste of resources. Tangerine peel is rich in functional components such as flavonoids, carotenoids and carbohydrates, which have great development and application value. "Compendium of Materia Medica" records: Tangerine peel, bitterness can relieve dryness, pungentness can disperse, and warmth can be mild; it treats all kinds of diseases, always take its power of regulating qi and drying dampness, and it is toni...
