[0034]

[0035]

[0036] The preparation method of described 3D printing shrimp minced meat-fat composition comprises the following steps:

[0037] Under the condition of 2-5°C, remove the heads, shells, and guts of fresh shrimps to obtain shrimp meat, first empty the ground for 5 minutes, add 3% of the weight of the shrimp meat and grind for 2 minutes, and then add the shrimp meat of 3% % cooking wine, 1% monosodium glutamate, 1% white granulated sugar and g...

[0038] Experimental Example 1 Composition 3D Printing Accuracy and Stability

[0039] The 3D printed shrimp meat-fat composition of Examples 1 to 9 and Comparative Example 1 was 3D printed with a nozzle with a diameter of 1.20mm, and the molding effect of the printed product was recorded in the LED light box, and the side length and the length of the printed product were measured with a vernier caliper. High size, compared with the ideal size of the target model, the printing accuracy is evaluated using the ratio of the length of the printed object to the length of the model. All printed products were placed in a room temperature environment of 25°C for 60 minutes to measure the height and calculate the printing stability index of the product.

Abstract

The invention belongs to the technical field of novel food processing, and particularly relates to a 3D printing minced shrimp-fat composition and a preparation method thereof. The composition comprises minced shrimp and fat accounting for 2-6% of the minced shrimp in mass, the apparent viscosity eta of the composition is 2000-4500 Pa.S, continuity of the minced shrimp 3D printing process is guaranteed, and a 3D printing product has high accuracy; meanwhile, the rheological unit link strength AF of the minced shrimp is controlled to be 2500-4500 Pa.S1 / z, it can be guaranteed that the 3D printing product has good mechanical performance, and the 3D printing product has high stability. By means of the 3D printing minced shrimp product, the printing accuracy reaches 90% or above, and the printing stability reaches 91% or above; and the preparation method is simple, easy to control and suitable for large-scale industrial production, 3D printing products in various shapes are prepared, and high economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of novel food processing. More specifically, it relates to a 3D printed shrimp mince-fat composition and a preparation method thereof. Background technique [0002] Three-dimensional rapid prototyping printing, referred to as 3D printing, refers to the technology of using computer software to design a 3D model and adding materials layer by layer through a 3D printer to manufacture a three-dimensional product. It is different from the subtractive manufacturing of traditional manufacturing, and has the characteristics of fast, convenient, flexible, high-precision, high-quality, and low-cost. The advantage of 3D printing technology is that it can directly generate objects of any shape from computer graphics data without machining or molds, and can produce shapes that cannot be produced by traditional food production techniques. With a good design concept and design process, the food development and processing...
