Problems solved by technology

Our most common sugar painting is flat sugar painting. Craftsmen will splice flat sugar paintings into many three-dimensional sugar paintings of different shapes. The skill requirements for craftsmen are very high, because of their high cost, long time consumption and processability. Shortcomings such as poor sex have seriously restricted the inheritance and development of Chinese sugar painting

preparation example Construction

[0033] A preparation method for sugar gel 3D printing soft material, comprising the steps of:

[0034] 1) Preparation of glycoprotein complex: sugar grafting reaction of protein and sugar by ultrasound-assisted method;

[0035] In order to effectively strengthen the functional properties of proteins, improve the rheological properties of sugar gel soft materials, and improve the grafting efficiency of sugar and protein, the sugar and protein were ultrasonically treated by ultrasonic-assisted method, and the glycoprotein after ultrasonic treatment was subsequently processed. It has good stability when printing.

[0036] 2) Preparation of emulsifier: dissolving polyglycerol fatty acid ester in water, heating and stirring to dissolve, forming emulsifier for later use;

[0037] 3) Preparation of curing agent: dissolving calcium gluconate in water to form a curing agent for subsequent use;

[0038] 4) Preparation of coagulant aid: mix carrageenan and cocoa butter in proportion re...

Embodiment 1

[0050] Mix protein and sugar at a mass ratio of 1:1, dissolve in PBS buffer solution with pH 7.0, stir magnetically at room temperature for 2 hours, preheat to 80°C, place the mixture in an ultrasonic device, ultrasonic power 260W, protein concentration is 10mg / mL, ultrasonic time is 15min, after the reaction is completed, it is cooled to room temperature rapidly. Dissolve polyglyceryl fatty acid ester in water, the ratio of polyglyceryl fatty acid ester to water is 1:4, the heating temperature is 70°C, and the heating time is 5 minutes to form an emulsifier for later use; slowly add calcium gluconate powder into water, gluconic acid The ratio of calcium to water is 1:1, the water temperature is 100°C, and the time is 2 minutes, and magnetic stirring is performed to form a curing agent. Slowly add an appropriate amount of carrageenan powder into dewatered water, swell at room temperature for 60 minutes, and perform magnetic stirring at 90°C until the carrageenan powder is comp...

Embodiment 2

[0052] Mix protein and sugar at a mass ratio of 1:2, dissolve in PBS buffer at pH 7.0, stir magnetically at room temperature for 2 hours, preheat to 80°C, place the mixture in an ultrasonic device, ultrasonic power 280W, protein concentration 12mg / mL ultrasonic time is 20min, after the reaction is completed, it is cooled to room temperature rapidly. Dissolve polyglyceryl fatty acid ester in water, the ratio of polyglyceryl fatty acid ester to water is 1:5, the heating temperature is 80°C, and the heating time is 7 minutes to form an emulsifier for later use; slowly add calcium gluconate powder into water, gluconic acid The ratio of calcium to water is 1:2, the water temperature is 110°C, and the time is 3 minutes, and magnetic stirring is performed to form a curing agent. Slowly add an appropriate amount of carrageenan powder into dewatered water, swell at room temperature for 80 minutes, and perform magnetic stirring at 95°C until the carrageenan powder is completely dissolv...

Abstract

The invention discloses a sugar gel 3D printing soft material and a preparation method thereof. The preparation method comprises the following steps of firstly, carrying out sugar grafting reaction onsugar and protein to obtain a glycoprotein compound, mixing the compound with an emulsifier, a curing agent and coagulant aids in proportion, and then printing by using a 3D printer. According to themethod, sugar and protein are used as raw materials, polyglycerol fatty acid ester is used as the emulsifier, calcium gluconate is used as the curing agent, carrageenan and cocoa butter are used as coagulant aids, the technology has the advantages of good continuity and high precision, a printing outlet is not blocked during printing, and the inheritance and development of the modern food processing technology on the traditional handicraft are realized.

Description

technical field [0001] The invention belongs to the technical field of 3D printing food processing, and relates to a sugar gel 3D printing soft material and a preparation method thereof. Background technique [0002] Chinese sugar painting is a traditional folk handicraft and an intangible cultural heritage popular in northern China. Our most common sugar painting is flat sugar painting. Craftsmen will splice flat sugar paintings into many three-dimensional sugar paintings of different shapes. The skill requirements for craftsmen are very high, because of their high cost, long time consumption and processability. Shortcomings such as poor sex have seriously restricted the inheritance and development of Chinese sugar paintings. [0003] As an emerging technology, 3D printing technology has been successfully applied in the food field. Through the principle of layer-by-layer manufacturing and layer-by-layer superposition, 3D printing technology can not only manufacture food wi...
