Problems solved by technology

The production principle of 3D printing technology is to push the material through the nozzle and deposit it layer by layer to generate the desired structure. However, the problem with existing materials is how to maintain their fluidity when passing through the nozzle under pressurized conditions, and behave as remain solid for printed structures, however, the biocompatibility of the emulsion molecules currently used for stabilization and crosslinking is problematic
This step, along with the production step of adding crystalline particles used as stabilizers, tends to reduce the biocompatibility of the material and reduce its range of applications in food

Abstract

The invention relates to the technical field of manufacturing of 3D printing materials, in particular to a method for manufacturing an edible 3D printing material by using chickpea protein, and the method comprises the following steps: 1) purifying the chickpea protein; (2) preparing an oil-in-water emulsion; 3) measuring the size of the liquid drop; 4) carrying out rheological property measurement; 5) carrying out confocal laser scanning microscope (CLSM) measurement; and 6) carrying out 3D printing of the emulsion. The purpose of preparing the 3D printing emulsion by using the chickpea protein is achieved, the 3D printing emulsion has good stability and viscoelasticity and can be extruded to pass through a nozzle of a printer, adhered chickpea protein particles after pH adjustment can be used as physical crosslinking among oil drops, no additional treatment is needed, a stent with the elastic-plastic rheological property better than the critical stress, and the independence required by 3D printing is met.

Description

Technical field [0001] The present invention relates to the field of production of 3D printing materials, and more particularly to a method of fabricating elastic 3D printing materials applicable to food and pharmaceutical sectors. Background technique [0002] 3D printing materials are of great significance for producing pharmaceutical brackets and special food. Making 3D printing materials is usually highly viscous, extruded by the nozzle of the 3D printer, and has an independent ability. The principle of the 3D printing technology is that the material is pushed by the material through the nozzle and deposits the desired structure, and the problem of existing materials is, how is the fluidity of its fluidity while pressurizing the nozzle, and manifested during still Keep the printed structure, however, there is a problem with the biocompatibility of emulsion molecules for stabilization and crosslinking. [0003] One way to make edible 3D materials is to use highly concentrated ...
