Abstract

The present invention discloses a preparation method of easy-to-dissolve laver powder. The method comprises the following steps: (1) crushing dried laver raw material; (2) uniformly mixing the laver powder with water according to a mass ratio of 1:20 to 1:40 to obtain a slurry body, and carrying out ultrasonic treatment on the slurry body; (3) adding a composite enzyme accounting for 0.1-0.5% by total mass of the laver powder into the slurry body after the ultrasonic treatment, and conducting enzymolysis for 0.5-2h; (4) conducting enzyme deactivation treatment, and then adding xanthan gum accounting for 0.1-0.5% by mass of the enzyme-deactivated slurry body to the enzyme-deactivated slurry body; (5) conducting colloid mill treatment and homogenization treatment on the slurry added with thexanthan gum; (6) carrying out ultra-high-temperature instantaneous sterilization treatment on the treated slurry; and (7) conducting spray drying to obtain the easy-to-dissolve laver powder. The embodiment of the invention also provides a laver drink prepared by using the preparation method of the easy-to-dissolve laver powder. The added value of the laver product can be improved by applying theembodiment of the invention.

Description

technical field [0001] The invention relates to a preparation method of a laver product and a prepared product, more particularly to a preparation method of an easily soluble laver powder and a prepared product. Background technique [0002] Seaweed is more and more popular because of its rich nutrition, low fat and cholesterol content, low price, and special physiologically active substances, and has gradually become a new direction for the development of human health food. Studies have shown that seaweed contains a large amount of protein, carbohydrates (mainly polysaccharides) and a small amount of crude fiber and fat, and also contains calcium, phosphorus, iron, iodine, alanine, glutamic acid, aspartic acid, phycoerythrin , Phycocyanin, phospholipids, triglycerides, carotene, vitamins B1, B2, C, niacin, biotin, lutein, chlorophyll, organic acids and volatile oils and many other nutrients. Laver is one of the seaweeds with the richest protein content, and the protein it ...
