Descripción

This study aimed to evaluate the effects of different concentrations of microencapsulated Hymenaea martiana bark extract (HM-BE) on the physicochemical and sensory characteristics of lamb burgers. Five treatments were evaluated: CON (control, no added antioxidant), BHT (butylated hydroxytoluene; 0.01 g BHT/100 g fat), and three levels of HM-BE inclusion: HM-BE0.11 (0.11 g/100 g meat batter (MB)), HM-BE0.55 (0.55 g/100 g MB), and HM-BE1.1 (1.1 g/100 g MB). The following parameters were assessed: proximate composition (moisture, protein, fat, and ash), texture profile, cooking loss, water-holding capacity, and sensory attributes. In addition, instrumental color (L∗, a∗, b∗), pH, and lipid oxidation (TBARS) were monitored on days 1, 7, 14, and 21 of refrigerated storage. The extract had no effect on proximate composition or texture profile (p >0:05). However, L∗ values were significantly affected by both antioxidant source and storage duration (p <0:0001). Lipid oxidation was effectively delayed by the extract, with HM-BE0.55 and HM-BE1.1 showing the greatest antioxidative capacity, while HM-BE0.11 demonstrated activity comparable to BHT. In sensory analysis, HM-BE1.1 achieved the highest scores for appearance, aroma, and flavor (p<0:01). In conclusion, HM-BE proved effective in improving oxidative stability and sensory acceptance of lamb burgers without compromising proximate composition or texture. The extract showed performance comparable or superior to BHT, confirming its potential as a natural alternative to synthetic antioxidants in meat products and supporting its use in the development of healthier, clean-label formulations.
