Preparation method of sturgeon floss
Technical Field
The invention belongs to the technical field of aquatic product processing, and relates to a preparation method of sturgeon floss.
Background
Sturgeons belong to the orders teleostomia, telenya, teleostomia, and sturgeon. The activated stone is produced in various places of the coast and various large waters of the south and north, is large economic fish, and is one of a few activated stones living in water in the world.
In recent years, with the improvement of sturgeon breeding and breeding technologies, the sturgeon breeding industry in China is rapidly developed and becomes one of the largest countries of the sturgeon breeding industry in the world, and the total breeding amount accounts for more than 80% of the total world. However, at present, most of sturgeon product development and utilization in China still stay in the most primary eating stage, mainly selling fresh sturgeons and frozen sturgeon meat, but compared with other economic fishes, the sturgeon meat has heavier fishy smell and is difficult to accept by some consumers, so that the culture profit is low, and the phenomena of yield increase and no synergistic effect are caused. In addition, because sturgeon sexual maturity period is long, investment is large, risk is high, only a small amount of sturgeons are used for breeding and processing caviar products in China, and sustainable development of sturgeon industry is severely restricted.
Sturgeon has very high nutritive value, researches show that sturgeon muscle contains rich protein and more than ten kinds of amino acids necessary for human bodies, and the content of the amino acids in sturgeon dry matter is 80 percent higher than that in globefish and eel. The sturgeon muscle fat contains various unsaturated fatty acids, is balanced in proportion and meets the human body demand pattern, wherein the DHA and the EPA (also called brain gold) are up to 12.5 percent, and the sturgeon muscle fat has good effects of softening heart and cerebral vessels, promoting brain development and preventing senile dementia. In addition, the sturgeon meat has less connective tissue content, shorter muscle fiber, loose protein tissue, high water content, easy digestion and absorption and high utilization rate up to 90 percent, and is a high-quality processing raw material.
In the processing method of the dried fish floss, firstly, the raw materials are processed, and the dried fish floss is easily caked and unevenly loosened by the processing methods of steaming, frying, rubbing, picking and the like; the second method is a processing method comprising the steps of raw material treatment, pre-baking, rolling, frying loosening and the like, wherein the pre-baking process needs lower pre-baking temperature but longer time in order to prevent the phenomena of protein denaturation and shrinkage and uneven surface and inside water distribution, and the surface discoloration phenomenon easily occurs in the baking process to influence the sensory quality of finished products.
The dried fish floss product has high soluble protein content and low fat melting point, is easy to digest and absorb by human bodies, and is helpful for the nutrient intake of children and patients. Is a recognized nutritional health food. However, the existing dried fish floss is mostly prepared from teleost fish, and no report about the sturgeon dried fish floss is provided. The whole cartilage of the sturgeon is not stabbed, and the invention can provide a simple and easily-obtained preparation method for the sturgeon floss.
