Problems solved by technology

This method is easy to use and has a good deodorizing effect, but the operation is complicated, the loss of nutrients in the seaweed is high, and the color and texture of the seaweed cannot be maintained to a certain extent, and there are many microorganisms remaining, which cannot guarantee the safety of eating, and the quality of the product cannot be guaranteed. Cannot achieve optimization

Abstract

The present invention discloses a deodorization method of seaweed. The method comprises raw material pretreating, yeast activation liquid preparing, seaweed compound deodorizing, and post-treating; wherein the seaweed compound deodorizing consists of yeast fermenting, acidification reacting and calcium alginate embedding. The compound deodorizing is more thorough in deodorization effects than thatof the single deodorization method. The compound deodorization method is used to achieve the purpose of the complete deodorization of the seaweed, more suitable for needs of consumers, and simple inoperations and excellent in the deodorization effects, and enables the seaweed to be less in microbial bacterium residues and safe to eat.

Description

(1) Technical field [0001] The invention relates to a method for removing fishy smell from seaweeds such as kelp, seaweed and wakame. (2) Background technology [0002] Seaweed is crisp and tender, has a good taste, is rich in nutrition, contains a variety of physiologically active ingredients, and has high medicinal and health effects, and is widely favored by consumers. However, fresh seaweed has a heavier fishy smell (far more than freshwater products), and the color and texture of processed seaweed are far inferior to raw seaweed, which reduces the preference of some consumers for it, and also has a certain impact on the sensory quality of seaweed products. development of the seaweed processing industry. The composition of fishy substances in seaweed is complex, mainly including: organic bromide or iodide, alcohols, aldehydes and ketenes. At present, physical, chemical and biological methods are often used to deodorize seaweed. The physical method mainly reduces the c...
