Problems solved by technology

[0003] At present, shrimp skins generally sold in the market are mainly eaten by consumers in soup or in other foods, and they need to be reheated and eaten together. Problems such as single form and narrow market sales
On the other hand, hot air drying is mainly used for rough processing of hairy shrimp after salvage. The obtained shrimp skin not only has poor product quality and high impurity content, bu

Embodiment 1

[0026] A preparation method of instant dried shrimp skin includes the following steps:

[0027] Step 1: Clean the shrimp skins: After pre-drying the raw shrimp skins, use a wind sorting machine for wind sorting. The wind power is 5m / s to remove fine impurities and light shrimps. Use a magnet strip to remove the magnetism in the raw shrimp skins. Metal; visually distinguish impurities, remove visible bamboo, wood, stone, glass, nylon, hair, crab, fish, shell impurities, and remove spoiled raw shrimp skin;

[0028] Step 2: Soaking and removing impurities: Put the shrimp skins cleaned in the step 1 into a container with a filter screen with a mesh diameter of 3mm. Put the container into the cleaning bucket, add 2% salt water and soak for 7 minutes, and Stir the shrimp skins, take out the container with a strainer to filter the brine, and thoroughly remove the foreign matter adhering to the shrimp skins;

Abstract

The invention belongs to the technical field of food processing, and particularly relates to a production method of instant dried small shrimps, wherein the production method comprises the following steps: step one, cleaning small shrimps; step two, soaking and removing impurities; step three, carrying out centrifugal dehydration; step four, seasoning the small shrimps; step five, cooking; six step, drying; and step seven, packaging. According to the production method of the instant dried small shrimps, the obtained instant dried small shrimps have the advantages of high quality, good taste, excellent color and luster, and easy chewing; volatile salt-based nitrogen is effectively removed, and the removal rate is 80% or more; with adopting of a new microwave spouting drying technology, energy is saved by 70% or more than that of general hot wind drying; the product has extremely low microbial content, the total number of bacteria is 5000 cfu/g or less, and no pathogenic bacteria are detected. The preparation method is simple, and is more energy saving and is more prone to realization of productization production compared with conventional drying.

Description

Technical field [0001] The invention belongs to the technical field of food processing, and specifically relates to a method for preparing instant shrimp skins. Background technique [0002] Shrimp skins have high nutritional value. According to related studies, the organic calcium and organic phosphorus content in 100g shrimp skins is as high as 991mg and 582mg, which is a good source of calcium and phosphorus for consumers. The protein content of each 100g shrimp skins is 39.3g, which is much higher than that of large yellow croaker. , Rice field eel, prawns, hairtail, pomfret and other aquatic products as well as beef, pork, chicken and other meat products; shrimp skin is rich in mineral elements, in addition to the iodine element lacking in terrestrial and freshwater organisms, its iron, calcium, phosphorus The content is also very rich, especially the calcium content is unmatched by any food, so astaxanthin is called "calcium storehouse". According to literature records, dr...
