Method for coloring dried sea cucumbers by using natural food material

Abstract

The invention belongs to the technical field of stichopus japonicus processing and particularly relates to a method for coloring dried sea cucumbers by utilizing a natural food material. The coloringmethod comprises the following specific operation steps: S1, selecting raw materials: black rice, distilled water and dried sea cucumbers; S2, executing preprocessing: drying the black rice, then executing wall breaking, and meanwhile drying the dried sea cucumbers; S3, extracting a pigment: heating the wall-broken black rice and distilled water together, and filtering out the black rice to obtaina grain color colorant; S4, executing coloring: placing the dried sea cucumbers and the colorant into a stirring kettle for heating and coloring; S5, executing drying: drying the colored dried sea cucumbers again to obtain the finished product. According to the scheme, the natural pigment contained in the grains is used for coloring the sea cucumbers, so that the sea cucumbers are naturally colored, do not fade, are safe and harmless, and the quality of the sea cucumbers is greatly improved.

Description

technical field [0001] The invention relates to the technical field of japonicus processing, in particular to a method for coloring light-dried sea cucumbers by using natural ingredients. Background technique [0002] Apostichopus japonicus is the largest aquaculture species in the northern seas of my country, with an annual output value of more than 10 billion yuan. With the research and development of processing technology, a series of new products such as high-pressure japonicus japonicus, instant japonicus japonicus, japonicus capsules, and japonicus oral liquid However, in the post-processing of sea cucumbers, light-dried sea cucumbers are still the most important processed sea cucumbers because they are easy to store, easy to transport, and have low requirements for equipment. However, the body color of sea cucumbers processed by this method The difference from the natural state is quite large, which affects the perception of consumers. Some vendors use chemical agents s...

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for coloring light-dried sea cucumbers by using natural food materials, so as to solve the post-processing of sea cucumbers proposed in the above-mentioned background technology. Light-dried sea cucumbers are easy to store, easy to transport, and have low requirements for equipment. It is still the most important processed product of japonicus japonicus, but the body color of japonicus japonicus processed by this method is quite different from the natural state, which affects the perception of consumers. Some vendors use chemical agents such as ferrous sulfate etc. to maintain the natural body color of sea cucumbers, but this method has great potential safety hazards, which is not conducive to the healthy development of the sea cucumber industry in the long run
