Problems solved by technology

The above-mentioned deodorization treatment methods are conventional acid-base treatment and blanching treatment to remove the fishy smell. Add acidic substances or deodorizing mixtures to the kelp for heating and cooking to remove the fishy smell. There are phenomena such as incomplete deodorization of kelp or overcooked kelp. Bring a lot of inconvenience to large-scale industrial production
[0004] On the other hand, sea velvet has a fishy smell. Due to its special organizational structure, the fishy substance in its reticulated loose tissue is more than that of kelp. Therefore, the method of removing fishy smell that is suitable for kelp is not necessarily applicable to sea velvet. It is urgent to find a method that can be specially used to remove the fishy smell of sea velvet

Abstract

The invention discloses a deodorization method for seaweed, and a preparation method for instant seaweed, and belongs to the technical field of food. The method comprises the following steps of: dipping the seaweed in water, and carrying out ultrasonic deodorization on the seaweed, wherein the water contains one or multiple of tea powders and glycyrrhizae radix. In the method, the tea powders andthe glycyrrhizae radix powders are directly used as a deodorization liquid, meanwhile, ultrasonic treatment is taken as an assistance, so that the tea powders and the glycyrrhizae radix powders can bemore favorably accelerated to fully perform absorption, oxidation resistance and coverage functions of the tea powders and the glycyrrhizae radix powders, and the fishy smell ingredients of the seaweed are lowered to 23.72% from 92.49% so as to indicate that the tea powders, the glycyrrhizae radix powders and ultrasound have a synergistic effect on an aspect of seaweed fishy smell removal.

Description

technical field [0001] The invention relates to a method for deodorizing sea velvet and a preparation method for ready-to-eat sea velvet, belonging to the technical field of food. Background technique [0002] Sea velvet is a kind of light black giant seaweed in seaweed. It is a wild and natural deep-sea plant. Because of its special growth environment and short picking period, it is a kind of green natural food with rich nutrition and delicious taste among brown algae in seaweed. Sea velvet is rich in calcium, iodine, iron, potassium, fiber, carotene, alginate and many other indispensable nutrients for the human body. It is actually the most healthy and delicious nutritious food nowadays. [0003] At present, among the existing kelp deodorization treatment methods, CN105010637A discloses a kelp tea and a preparation method thereof, adding citric acid solution to deodorize, and the concentration of citric acid solution is 7.5-20g L -1 , the deacidification temperature is 40...
