Embodiment

[0012] Example: add the collected kelp slag to clean water, heat it to 60°C, wash it after soaking, dehydrate it with a centrifuge, and then dry it to a moisture content of 45%, then send it to a linkage colloid mill, add water 5 times to grind it into a slurry , and then put it into an ultrasonic reaction kettle, add 1% compound enzyme, heat at 52°C, ultrasonic treatment time is 2 hours, and the ultrasonic power is 500w, then add bleaching agent and stabilizer to the slurry for bleaching treatment, and then use it after centrifugal filtration An appropriate amount of 95% ethanol is dehydrated and precipitated, and the precipitate obtained by the separation and alcohol precipitation is vacuum-dried at a temperature of 70°C to a moisture content of 5% to obtain kelp dietary fiber.

Abstract

The invention belongs to the field of food processing, and in particular relates to a method for preparing seaweed dietary fibers via ultrasonic enzymolysis. The method is characterized by comprising the following steps: carrying out heating and immersion cleaning, dewatering and drying, colloid pulping, ultrasonic enzymolysis, bleaching treatment, separation and alcohol leaching, vacuum drying and the like on seaweed residues as raw materials so as to obtain the seaweed dietary fibers. The production method which is simple in treatment process, easy to industrialize and low in production cost, can reduce the enzyme adding amount and ensures that the seaweed dietary fibers are safe to eat, is provided. Thus, the effective value-added utilization of the seaweed residues is realized. The method has high economic and social benefits.

Description

Technical field: [0001] The invention belongs to the field of food processing, and in particular relates to a method for preparing kelp dietary fiber by ultrasonic coal hydrolysis. Background technique: [0002] my country is rich in kelp resources and is also the country with the largest kelp production in the world. As food and traditional Chinese medicine raw materials, kelp not only contains rich protein, vitamins and minerals, but also contains alginic acid, mannitol, kelp amino acids, organic iodine, and cell stimulation. Ingredients with unique biological activity, such as toxins, multi-halogen and multi-mushroom compounds, sterol compounds, brown algae starch, and dietary fiber. Except for a small part of kelp that is sold fresh and developed into various foods, most of it is used as the main raw material of seaweed chemical industry to produce alginic acid, iodine and mannitol with traditional production technology. The annual output of alginic acid in my...
