Description

Producing Method of 3D Print Ink Containing Oyster An embodiment of the present invention relates to a method for manufacturing oyster-containing 3D printing ink. [National R&D projects that supported this invention] Ministry Name: Busan Metropolitan City Project Management Agency: Busan Technopark Foundation Research Project Name: Field-Oriented Technology Development Project for Innovative Growth in Processed Seafood Research Project Title: Development of Senior-Friendly Personalized Oyster Convenience Food Using 3D Printing Technology Contribution rate: 100% Organizing Institution: Pukyong National University Industry-Academic Cooperation Foundation Research Institute: May 13, 2022 – November 30, 2022 Korea's elderly population is rapidly increasing due to a declining birth rate and rising life expectancy, and consequently, consumption by the elderly aged 60 and over is expected to account for more than half of total consumption by the 2050s. However, the Korean market for senior-friendly foods remains in its early stages compared to overseas markets due to issues such as a lack of awareness, insufficient product planning, and technological development. Senior-friendly foods need to be developed on a personalized basis, and to this end, using 3D printing for food manufacturing is appropriate. While 3D printing allows for the free control of food shapes and physical properties, the development of food inks used in 3D printing is still insufficient, and among them, 3D food printing using seafood requires even more research. FIG. 1 is a flowchart illustrating a method for manufacturing oyster-containing 3D printing ink according to an embodiment of the present invention. Figure 2 is a flowchart showing the detailed steps performed in the preprocessing stage. Figure 3 is a flowchart showing the detailed steps performed in the oyster powder manufacturing process. Figure 4 is a flowchart showing the detailed steps performed in the step of manufacturing 3D printing ink in paste form. Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The following detailed description is provided to facilitate a comprehensive understanding of the methods, apparatuses, and/or systems described herein. However, this is merely illustrative and the disclosed embodiments are not limited thereto. In describing the embodiments, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions could unnecessarily obscure the essence of the disclosed embodiments. Furthermore, terms described below are defined in consideration of their functions in the disclosed embodiments, and these may vary depending on the intent or practice of the user or operator. Therefore, such definitions should be based on the content throughout this specification. Terms used in the detailed description are intended merely to describe the embodiments and should not be limiting. Unless explicitly stated otherwise, expressions in the singular form include the meaning of the plural form. In this description, expressions such as "include" or "comprise" are intended to refer to certain characteristics, numbers, steps, actions, elements, parts thereof, or combinations thereof, and should not be interpreted to exclude the existence or possibility of one or more other characteristics, numbers, steps, actions, elements, parts thereof, or combinations thereof other than those described. In this invention, oysters, known as high-protein seafood, were processed into powder to develop them into 3D printing ink, and starch (potato starch) can be used to control the physical properties of the 3D printing ink. Starch possesses physical properties that improve not only nutritional aspects but also the texture, palatability, and quality of food, so it can be used as a food thickener. In particular, when starch is heated or cooled, it is converted into cross-linked starch, a type of modified starch, forming a rigid polymer network structure, which allows for the control of physical properties by mixing with other materials. FIG. 1 is a flowchart illustrating a method for manufacturing oyster-containing 3D printing ink according to one embodiment of the present invention. Referring to FIG. 1, to manufacture an oyster-containing 3D printing ink, the method may include a step of pre-treating an oyster (S10), a step of producing oyster powder from the pre-treated oyster (S20), and a step of mixing the oyster powder, additives, and water to produce an oyster-containing 3D printing ink (S30). Detailed steps performed in each step will be described later. Figure 2 is a flowchart showing the detailed steps performed in the preprocessing step (S10).
