Blended meat/plant products are capturing industry market space at the retail counter for value-added beef products. Plant protein ingredients can be added to meat formulations to create appealing and functional products. Ground beef was combined with one of three plant protein inclusion treatments: control, pea, oat, or rice, along with 5% textured vegetable protein (TVP) and 1.5% soy protein concentrate then formed into 226 g patties containing up to 10% plant-based proteins. Patties were analyzed for fresh and cooked characteristics throughout a 5- or 7-day retail display. The inclusion of plant-based proteins negatively affected the instrumental tenderness values which were greater ( p < 0.01) in plant-inclusion patties compared to the control patties. The inclusion of plant proteins increased ( p = 0.01) the cooking yield of patties compared to the control. Cooking time was longer ( p = 0.04) for oat patties compared to the control patties. Cooked color values for vegetable inclusion patties did not affect ( p = 0.12) lightness (CIE L*) values; however, redness (CIE a*) was greater ( p < 0.01) for rice than all other treatments and yellowness (CIE b*) values were greater ( p < 0.01) for all protein treatments compared to the control. Rice improved ( p < 0.01) fresh a* values on day 5 of display compared to the control; whereas pea decreased ( p = 0.04) values compared to the control. There was a treatment × day interaction ( p < 0.01) on lipid oxidation values with a reduction in values on day 3 for all vegetable proteins compared to the control and on day 7 lipid oxidation was reduced ( p ≤ 0.03) for oat patties. |
