Abstract
In this study, the effect of different types of starch (potato, wheat, corn, tapioca, and mung bean) on the quality of three-dimensional (3D) printed food products containing tomato-starch paste (TSP) was investigated. The printability of TSP was evaluated by examining its rheological and textural properties and the microstructure of 3D printed products. The results showed that the tomato starch paste containing wheat starch had the best printing accuracy and print quality compared to the other samples, which had an extruded line width of 0.93 mm and center heights and diameters of 18.56 mm and 20.15 mm. The macrorheological and microrheological analysis results showed that the apparent viscosity, loss modulus, storage modulus, and viscoelasticity of the TSP containing wheat starch were significantly higher than those of the other samples (P < 0.05). Low-field nuclear magnetic resonance (LF-NMR) results showed that T21 and T22 of TSP containing wheat starch significantly decreased, thereby improving the retention of printed shapes and deposition of 3D-printed TSP. The analysis of textural properties showed that TSP containing wheat starch had significantly higher strength in terms of hardness, elasticity, cohesion and chewiness, which were 9.58 N, 0.58, 0.31 and 2.13 N, respectively (P < 0.05). Thus, the pseudoplastic gel formed by TSP containing wheat starch exhibited a higher fluidity and structural density than the other samples, which improved the extrudability and shape stability of the printed product as well as the self-supporting properties of TSP.
期刊介绍:
LWT - Food Science and Technology is an international journal that publishes innovative papers in the fields of food chemistry, biochemistry, microbiology, technology and nutrition. The work described should be innovative either in the approach or in the methods used. The significance of the results either for the science community or for the food industry must also be specified. Contributions written in English are welcomed in the form of review articles, short reviews, research papers, and research notes. Papers featuring animal trials and cell cultures are outside the scope of the journal and will not be considered for publication.
