Fig. 6: Effect of heat exposure time on weight loss and shrinkage in printed chicken samples.
From: Precision cooking for printed foods via multiwavelength lasers
Each data point from each graph was from a different cooking test. a Weight loss percentage as a function of energy per area for laser-broiled and oven-broiled samples (sample size was 17 for blue laser tests and 6 for NIR laser tests). The power of both the blue and NIR lasers was 5 W for these trials. b Shrinkage as a function of energy per area for laser-broiled samples (sample size was 35 for blue laser tests and 11 for NIR laser tests). The power of both the blue and NIR lasers was varied from 5 to 10 W for these trials. Energy per area was calculated by taking the product of the laser power and the exposure time and dividing by the area of the food sample. Shaded regions represent the standard error estimate of the sample set, showing a 95% prediction interval based on the collected data.
