Method for preparing superfine shrimp sauce and shrimp meal from shrimp heads and dried shrimps

Abstract

The invention discloses a method for preparing superfine nano-scale shrimp sauce and shrimp meal nutriment which can be absorbed and utilized by human bodies by performing secondary processing on the waste shrimp heads and dried shrimps in aquatic product processing. The method comprises the following steps of: preparing the superfine shrimp sauce with the granularity less than 1 micro from the cleaned shrimp heads and dried shrimps by boiling, primarily crushing, softening the shrimp shells, finely crushing and ultra-micro grinding and refining; and preparing instant dried shrimp powder with the moisture content less than 7 percent through spray drying. The nano-scale product has smooth mouthfeel and delicious taste of fresh shrimps, and is particularly suitable to be used as a calcium supplement nutritional and health care food for the old and children.

Description

Technical field [0001] The invention relates to a production method for secondarily processing waste shrimp heads and shrimp skins in aquatic product processing into nano-scale shrimp sauce and shrimp powder nutritional products that can be easily absorbed and utilized by the human body. Background technique [0002] my country has a long coastline, and there are many shrimp farms distributed in thousands of kilometers of coastline and inland lakes from south to north. Coupled with the fishing of wild shrimp in the ocean, there is an annual output of nearly one million tons of shrimp. Nearly half of the shrimps are processed in one-time aquatic products, and the shrimp heads and shrimp skins after peeling off the shrimp can only be used as low-value additives for ordinary feed. There are also small amounts of prawns that are fermented and coarsely ground into traditional prawn head paste. But this shrimp head sauce is very rough, and only utilizes the protein fermentation ...

However, because its carapace is too hard, the digestive system of the human body cannot use the larger coarse particles. If it is crushed to the nanometer level, the human body will be able to directly absorb it through the intestinal wall.
