Embodiment 1
[0022] Accurately weigh 35g of pea starch, 15g of potato starch, put the rich persimmons into the juicer to squeeze the juice, take 2g of persimmon juice, and weigh 75g of water, add them to the compound starch, stir and mix well, and place in a constant temperature water bath Heat the gel in a water bath at 70°C for 0.5h; take out the gel starch and knead it into a dough, and then 3D print it to obtain a 3D printed object.
[0023] For the 3D printing material in this example, the TPA performance test was carried out using a texture analyzer, and the adhesion, hardness, viscosity, and elasticity of the printing material were measured at 64°C, 67°C, and 70°C during the gelation process. , the four index data are 0.43, 2700, 0.47, 0.835 in turn; at 67°C, the four index data are 0.31, 2900, 0.53, 0.673; at 70°C, the four index data are 0.17, 3500, 0.64, 0.541 ;Use the software Origin8.5 to draw a graph and get the performance test Figure 1-4 .
[0024] Depend on figure 1 and...
Embodiment 2
[0027] Accurately weigh 35g of pea starch and 25g of potato starch. Put the Jiro persimmons into the juicer to squeeze the juice, take 2g of persimmon juice, 76.5g of water and 13.5g of celery juice, mix the above materials, and stir evenly, then place in a constant temperature water bath The gel was heated in a water bath at 70 °C for 1 h in a pot.
Embodiment 3
[0029] Accurately weigh 70g of pea starch, 70g of potato starch, and put the Luotian and Jiro persimmons into the juicer to squeeze the juice, then take 10g of persimmon juice, 180g of water and 0.6g of acesulfame potassium, mix the above materials, and stir evenly. Heat the gel in a constant temperature water bath at 64 °C for 2 h.
[0030] The 3D printing materials in Examples 1-3 can be eaten immediately or after steaming and subsequent processing, and can also be directly used as food models, food ingredients, props, teaching aids, and sand tables.
