Preparation method of vacuum compression porphyra haitanensis

Abstract

The invention provides a preparation method of vacuum compression porphyra haitanensis. The produced porphyra haitanensis has high shaping performance and a small size; oxidization is avoided; the shelf life is prolonged; the problems such as the transportation and the preservation and the like of the conventional porphyra haitanensis are solved. A low-salinity washing method is adopted, so that the produced porphyra haitanensis is soft and easy to be shaped and high in the glossiness; the process of compression shaping and the process of vacuum packing are synchronously implemented; the porphyra haitanensis has high shaping performance; the size of a unit weight is reduced by near 10 times; the oxidization is avoided under the vacuum condition; the shelf period is prolonged; the bottleneck problems such as the transportation and the preservation and the like of the conventional porphyra haitanensis products are solved; the shape and the original flavor of the porphyra haitanensis can be greatly retained when eating the vacuum compression porphyra haitanensis.

Description

technical field [0001] The invention belongs to the technical field of laver processing, and in particular relates to a preparation method of vacuum-compressed laver. Background technique [0002] Porphyra laver is a kind of nutritious, delicious, precious seafood loved by people. Cultivated altar laver has the characteristics of low risk, stable production, large market potential and good economic benefits. After more than 40 years of development, the aquaculture area of ​​altar laver along the coast of my country has exceeded 300,000 mu, and 200,000 people are engaged in aquaculture, processing and sales of altar laver every year, with an annual output value of more than 1 billion yuan. It has become an important pillar in the aquaculture industry. industry. In addition, the large-scale altar seaweed artificial cultivation has absorbed a large amount of nitrogen, phosphorus and other elements in the coastal waters, greatly reducing the degree of eutrophication in the coas...

AI Technical Summary

Problems solved by technology

There have been some reports on the product processing methods of algae laver, such as the publication number CN104304427A, and the Chinese invention patent titled "a fresh-keeping method of algae laver" discloses pretreatment, bacteria reduction, freshness preservation, centrifugal dehydration packaging and preservation, etc. steps, but this method results in a non-dry product with high transportation costs and short shelf life

Another example is that the publication number is CN102524843A, and the Chinese invention patent titled "A Method for Processing Instant Seaweed with Altar Laver" discloses a production instant method for seasoning and high-temperature baking, but this method needs to use dried laver as a raw material for secondary processing
