Abstract
The objective of this work was to produce low moisture-texturized vegetable protein (LM-TVP). Firstly, SPI:DRB at ratio of 50:50, 65:35 and 80:20 (w/w) was blended to produce TVP with 50-70% protein (TSP50-70), respectively. In addition, RPI:DRB was also blended at the same ratio to produce non beany odor TVP with 50-70% protein (TRP50-70). All samples were extruded using twin screw extruder. Extrusion condition was fixed at 25% of feed moisture, 400rpm of screw speed and 130°C of die temperature. Next, properties of TSP50-70 and TRP50-70 before and after rehydration were characterized. For TSP50-70, studied properties consisting of expansion ratio, density, WAC, WHC and OHC of TSP50-70 were 2.20-2.27%, 0.26-0.34kg/m3, 414-446%, 2.87-4.88g H2O/g and 2.55-2.73g oil/g respectively. These properties values were closed and in the same range of commercial-TVP (C-TVP). However, texture of TSP50 and TSP70 was significantly different, as decreasing DRB content from 50 (TSP50) to 20% (TSP70) improved texture in terms of hardness (from 0.51 to 1.88N), springiness (from 0.73 to 0.96) and cohesiveness (from 0.46 to 0.81) of TSP. Therefore, to add value to DRB, TSP70 (80% SPI and 20% DRB) was proposed to produce TSP. For TRP, expansion ratio, density, WAC, hardness, springiness and cohesiveness of TRP50-70 were 1.07-1.34%, 0.63-0.88kg/m3, 78-158%, 1.03-9.10N, 0.71-0.85 and 0.27-0.29 which were out of range compared to C-TVP. © 2023 Walter de Gruyter GmbH, Berlin/Boston 2023.
