3D Printing Food for the Military - w/HSPublic

3D food printing (3DFP) produces food products using a cutting-edge manufacturing technique. The US Army Combat Capabilities Development Command (CCDC) Soldier Center has taken an interest in 3DFP to allow troops greater personalization in their diet in order to reduce food waste and increase calorie intake. However, research including taste-tests of 3D food products with human subjects has been limited. This study used 3DFP to design a 3-layer bar and assessed the psychosocial properties of the bars, including participants’ satiety, hedonic ratings, and perception of the bar as food, while simultaneously making iterative improvements to the bar and investigating attitudes towards new food technologies in future servicemen and women using survey methodology. Four different iterations of the bar were tested amongst nine participants. The average neophobia in the ROTC sample was 52.80 out of 91 (N = 45, SD = 8.83). Demographic differences were not explored given that most individuals identified as white, male, and were between 18 and 22 years of age. Further research on the acceptability of 3DFP is required to successfully implement this technology in the real world.
