Description

Method for making edible embossed slices

This application relates to a method for making edible embossed sheets, and more particularly to a method for making edible embossed sheets for use on pastries.

Traditional pastries can be molded into various shapes to meet consumer demand. However, traditional pastries cannot yet be made into photographic patterns; at most, they can only be made with specific text.

For example, Republic of China Invention Patent No. I302441 discloses a food decoration and processing system, which mainly includes an import device, an information processing device, a driving device, and a processing device. The import device is used to receive external information and convert it into digital files. The information processing device converts the digital files into movement path information and outputs it. The driving device receives the movement path and drives the processing device so that the processing unit outputs the ingredients on the food by means of painting, squeezing, placing, sprinkling, etc., to draw and decorate the food.

Although the aforementioned patents can achieve the purpose of displaying patterns on food, these patterns are easily damaged and are only suitable for immediate consumption. They cannot be displayed for a long time, which is somewhat insufficient for consumers.

To address the aforementioned issues, this application discloses a method for producing edible embossed sheets, which involves printing, molding, sheet making, and demolding steps to create edible embossed sheets that achieve image preservation.

To achieve the above objectives, this application provides a method for manufacturing an edible relief sheet, comprising the following steps: a printing step: creating a three-dimensional relief sheet using 3D printing; a molding step: placing the three-dimensional relief sheet in a groove of a master mold and pouring edible silicone into the groove until the silicone has solidified and set, after which a negative mold is removed; a sheet-making step: removing the three-dimensional relief sheet from the negative mold and pouring semi-transparent food material into a pattern groove of the negative mold; and a demolding step: after the semi-transparent food material has solidified, demolding an edible relief sheet from the negative mold.

In another embodiment of this application, the thickness of the 3D relief sheet is 1 mm to 5 mm.

In another embodiment of this application, the curing time of the edible silicone is 8 to 36 hours.

In another embodiment of this application, the curing time for the semi-transparent food ingredient is 10 minutes to 1 hour.

In another embodiment of this application, the translucent food ingredient is made from a first ingredient and a second ingredient. The first ingredient is selected from the group consisting of syrup, maple syrup, glutinous rice paste and chocolate, and the second ingredient is selected from the group consisting of artificial food coloring, red yeast rice powder, bamboo charcoal powder and turmeric powder.

To achieve the above objectives, another embodiment of this application provides a method for manufacturing an edible embossed sheet, comprising the following steps: a printing step: creating a three-dimensional embossed sheet using 3D printing; a molding step: placing the three-dimensional embossed sheet into a groove of a female mold, and pouring edible silicone into the groove until the silicone has cured and set, after which a female mold is removed; and a sheet-making step: removing the three-dimensional embossed sheet from the female mold, and shaping one of the images of the female mold. The sample tank is filled with semi-transparent food material; demolding step: after the semi-transparent food material has solidified, an edible relief sheet is demolded from the negative mold; and strengthening step: a strengthening mold with a forming groove is provided, the semi-transparent food material is poured into the forming groove and the edible relief sheet is placed in it, then the semi-transparent food material is poured in again so that the semi-transparent food material covers the edible relief sheet, and after solidification, a strengthened relief sheet is taken out from the strengthening mold.

Therefore, this application uses a negative mold formed by curing edible silicone to accurately replicate the details of the three-dimensional relief original, producing a semi-transparent edible relief sheet that can be combined with cakes and other pastries to enhance the personalization and uniqueness of the product, with broad application prospects and market potential.

The following description of exemplary embodiments of this application with reference to the accompanying drawings is not intended to limit the technical principles of this application to the specific disclosed embodiments, and the scope of this application is limited only by the scope of the patent application, covering alternatives, modifications and equivalents.

Please refer to Figures 1 and 2, which are flowcharts of a first embodiment of a method for producing an edible relief sheet according to this application, comprising the following steps:

Printing Step S1: A three-dimensional relief original 10 is created through 3D printing. In this embodiment, a digital photo file is input into a 3D printer and printed to create a three-dimensional relief original 10 corresponding to the digital photo pattern. The thickness of the three-dimensional relief original 10 is 1mm to 5mm. The digital photo file can be obtained through photography, taking pictures, or downloading from the internet, and can be in various forms such as portrait photos, couple photos, family photos, landscape photos, pattern photos, and object photos. In addition, the material of the three-dimensional relief original 10 is selected from materials such as ABS (Acrylonitrile Butadiene Styrene), PLA (Polylactic Acid), and nylon (also known as polyamide).

Step S2: Place the three-dimensional relief original piece 10 into a groove 21 of a female mold 20, and pour edible silicone 22 into the groove 21, so that the edible silicone 22 completely covers the groove 21 and the three-dimensional relief original piece 10, until the edible silicone 22 has cured and set, and then remove a female mold 30. The curing time of the edible silicone 22 is 8 to 36 hours.

Production step S3: Remove the three-dimensional relief original sheet 10 from the negative mold 30, so that a pattern groove 31 corresponding to the shape of the three-dimensional relief original sheet 10 is formed on one side of the negative mold 30. Then, pour the semi-transparent food material 32 into the pattern groove 31 of the negative mold 30. In this embodiment, the semi-transparent food material 32 is made of a first material and a second material. The first material is selected from the group consisting of syrup, maple syrup, glutinous rice paste and chocolate. The second material is selected from the group consisting of artificial food coloring, red yeast rice powder, bamboo charcoal powder and turmeric powder.

Demolding step S4: After the semi-transparent food material 32 has cured, demold an edible relief sheet 40 from the negative mold 30. The curing time for the semi-transparent food material 32 is 10 minutes to 1 hour.

Referring to Figures 2 and 3, this application utilizes the aforementioned manufacturing method to create an edible embossed sheet 40 corresponding to a digital photograph pattern for image preservation. The edible embossed sheet 40 is translucent, allowing it to be placed on a pastry 100. The pastry 100 can be a cake, and it has a translucent portion 101. The translucent portion 101 can be a hollow hole or a translucent edible material, such as jelly. The edible embossed sheet 40 is placed on the top surface of the translucent portion 101, and a light source 102 is located on the bottom surface of the translucent portion 101. The area of the edible embossed sheet 40 is equal to or greater than the cross-sectional area of the translucent portion 101. By illuminating the pastry 100 with light source 102, the visual effect of the pastry 100 is enhanced, and its uniqueness and individuality are improved, thereby increasing its added value and product price, and providing consumers with more diverse choices.

Therefore, this application is applicable to customized occasions such as weddings, birthdays, or other commemorative events, significantly enhancing the personalization and visual appeal of Pastry 100 and meeting market demand for innovative and personalized products. Furthermore, the edible embossed sheet 40 in this application is not only edible and safe to produce, but its image is also durable and realistic, allowing for more detailed patterns and greatly increasing the economic value of Pastry 100.

As shown in Figures 4 and 5, this is a flowchart of a second embodiment of the method for manufacturing an edible embossed sheet according to this application. The second embodiment differs from the first embodiment in that a strengthening step S5 is added after the demolding step S4 in the first embodiment. In the strengthening step S5, a strengthening mold 50 is provided, which has a forming groove 51. A semi-transparent food material 32 is poured into the forming groove 51, and then an edible embossed sheet 40 is placed in it. Then, the semi-transparent food material 32 is poured in again, so that the semi-transparent food material 32 covers the edible embossed sheet 40. After curing, a strengthened embossed sheet 60 is removed from the strengthening mold 50. The thickness of the strengthened embossed sheet 60 is 5mm to 20mm.

In this way, through the production of the second embodiment, the reinforced relief sheet 60 has better structural strength and improved durability.

In summary, the negative mold 30 formed by curing edible silicone 22 in this application can accurately replicate the details of the three-dimensional relief original 10, and produce a translucent edible relief sheet 40 that can be combined with cakes and other pastries 100 to enhance the personalization and uniqueness of the product. Therefore, the manufacturing method of this application combines 3D printing technology, edible silicone 22 molding, and translucent food sheet production, realizing the transformation of digital photos into edible relief sheets 40, improving the personalization and visual appeal of the product, and has broad application prospects and market potential.
