The invention discloses a water quality improver for aquaculture and a preparation method thereof, and belongs to the technical field of water quality improvement, walnut shell derivatives are subjected to acid pickling and calcination to obtain pretreated biochar, titanium dioxide / iron-manganese nanosheets are loaded to obtain composite biochar, composite bacteria are coated with sodium alginate-calcium chloride to form core-shell microspheres, and the core-shell microspheres are subjected to ball milling to obtain the water quality improver for aquaculture. Adding gelatin-tannic acid hydrogel to realize slow release, so as to obtain antibacterial composite hydrogel; the preparation method comprises the following steps: carrying out ball milling on composite biochar, bentonite, deionized water and hollow glass beads to obtain a main material, homogenizing and emulsifying cod liver oil and antibacterial composite hydrogel to obtain an auxiliary material, and processing by a pelleting machine to obtain the water quality improver for aquaculture. The three functions of adsorption, photocatalytic degradation and biological antibiosis are synergistically realized, and the removal rate of organic matters and the stability of water quality are improved.

The invention provides cod liver oil pure chitosan microspheres as well as a preparation method and application thereof, and belongs to the technical field of chitosan microspheres. The method comprises the following steps: uniformly stirring cod liver oil and a chitosan solution according to a volume ratio of 1: (2-6) to obtain an emulsion m1; extruding the emulsion m1 into a sodium dodecyl sulfate solution to obtain cod liver oil chitosan microspheres ms2; drying the cod-liver oil chitosan microspheres ms2, and putting the cod-liver oil chitosan microspheres ms2 into a sodium dodecyl sulfate solution for standing to obtain cod-liver oil chitosan microspheres ms3; immersing the cod-liver oil chitosan microspheres ms3 into a sodium hydroxide solution, and then washing the cod-liver oil chitosan microspheres ms3 to be neutral to obtain cod-liver oil chitosan microspheres ms4. Through a self-assembly technology at a mild temperature, a cross-linking agent does not need to be used, the preparation process is simple, and the obtained cod-liver oil pure chitosan microspheres are high in biological safety, good in antibacterial activity and high in embedding rate. The invention also provides application of the cod-liver oil pure chitosan microspheres in preparation of foods and medicines, and the cod-liver oil pure chitosan microspheres have a good application prospect.

The invention discloses a preparation method of compound protease-yeast synergistic aroma enhancement seafood flavor powder, which comprises the following steps: firstly, mixing raw materials such as euphausia superba powder, dried oyster powder, skipjack powder, shrimp shell powder, shiitake mushroom powder, kelp powder, fish collagen peptide, glycine, L-alanine and glucose; the papain and bromelain with specific enzyme activity are subjected to composite enzymatic hydrolysis to create a flavor precursor. Then, the enzymatic hydrolysate is fermented through pichia pastoris, disodium 5 '-ribonucleotide (I + G) is added synchronously, and rich aroma components such as pyrazine and sulfide are generated; after fermentation, laver powder, cod-liver oil, a phaffia rhodozyma fermentation extract rich in astaxanthin and ginger oleoresin are added for flavor locking and oil immersion homogeneous emulsification, and finally, a microporous granular product is prepared through compound wall material embedding and spray drying. According to the preparation method, biological enzymolysis, microbial fermentation and flavor targeted locking technologies are integrated, so that the aroma level, strength, stability and cold water instant solubility of the flavor powder are improved.
