Abstract: Disclosed is a method for preparing an easy-to-swallow composite gel based on high-pressure shear induction and belongs to the technical field of food processing. Marine products are used as raw materials. A cross-linking degree of thermally denatured proteins and a combination degree of functional oil are synchronously regulated, calculated and controlled by one-step of emulsion filling and protein cross-linking. A composite gel prepared has low strength, high water/oil retention rate and the properties of “soft” easy-to-swallow foods. The composite gel is enhanced in efficacy by nutrition regulation, and the prepared easy-to-swallow composite gel achieves precise nutrition regulation. The composite gel is differently shaped by 3D printing according to different people's needs to improve consumers' appetite for easy-to-swallow foods. The utilization rate of marine resources is fully improved, a fish meat base material can be prepared from leftover processed minced fish meat, so the added value of products is increased.

Abstract: A method for preparing a chemiluminescent hydrogel is disclosed, belonging to the field of luminescent materials. The method for preparing a chemiluminescent hydrogel includes the steps of: slowly adding chitosan to an acetic acid solution, stirring at room temperature until completely dissolved, adding a cobalt chloride solution, followed by a polyvinyl alcohol (PVA) solution, sufficiently stirring, ultrasonically defoaming, and subjecting a resulting mixture to an alkaline bath treatment with an alkaline solution, adding N-(4-aminobutyl)-N-ethylisoluminol (ABEI), and stirring with a hydrogen peroxide solution to obtain the chemiluminescent hydrogel. The synthesized hydrogel has the advantages of high luminous intensity and long duration. In the process, a high-water-cut polymer with a three-dimensional network structure obtained by chemical crosslinking with the addition of PVA features excellent biocompatibility, high elasticity, and nontoxicity, and is one of biomedical materials with application potential.
