Preparation method of nanoscale lophiiformes fish bone meal

Abstract

The invention relates to a preparation method of nano-scale anglerfish bone powder, comprising the following steps: removing meat scraps on the discarded anglerfish bone, cutting into pieces, cleaning surface stains, soaking in an aqueous solution of endopeptidase for enzymolysis, Cook and soften in a high-pressure environment, crush and sieve, soak in ZnCl2 solution overnight, take it out and dry it, and thermoplastically extrude fishbone powder with different water contents, and then get nano-scale anglerfish after treatment with atmospheric plasma radio frequency RF Fish bone powder, the particle size range of the angler fish bone powder prepared by the method of the present invention is in the nanometer level, the pore size is small, and the particle size distribution is uniform. it is good.

Description

technical field [0001] The invention relates to a preparation method of nano-scale anglerfish bone powder, belonging to the technical field of fish processing. Background technique [0002] Anglerfish, commonly known as toad fish and sea toad, is a cold-temperate bottom fish widely distributed in the eastern waters of my country (the northern part of the East China Sea, the Yellow Sea and the Bohai Sea). It has extremely high nutritional, edible and medicinal values. popular. In recent years, the demand for export has been strong, and the processing volume of anglerfish in my country has continued to increase, and both output and price have increased significantly. A large number of anglerfish bones produced after industrial processing are discarded as leftovers, or only used as fertilizer or feed, with low added value. [0003] Angler fish bones are rich in nutrients such as calcium, iron, zinc, magnesium, phosphorus, collagen, and chondroitin. If these ingredients are not...

Problems solved by technology

[0004] In the existing technology of utilizing fish bones, anglerfish bones are usually prepared into fish bone meal. The commonly used preparation methods include physical and chemical methods, but chemical methods are easy to cause secondary chemical reactions, which may bring food safety hazards to fish bone meal. The physical method generally refers to the change of the physical form of the grinding, no foreign substances are introduced, and the safety is high. However, the particle size of the fish bone meal prepared by grinding is large, usually in the micron or even millimeter level, and the particle size distribution is uneven, which limits the use of fish bone meal. Applications in food, medicine and other fields

Chinese patent 2015110072585, patent name fish bone powder and its preparation method, application date: December 30, 2015, discloses a preparation method of fish bone powder that is steamed, enzymatically hydrolyzed, baked and pulverized, through chemical and physical methods combined to prepare fish bone meal, but the particle size of the fish bone meal prepared by this method is still large, the particle size distribution is uneven, and the particle hardness of the fish bone meal is relatively large
