The aim of this study was to evaluate the influence of different concentrations of inulin and pectin as fat substitutes on the chemical composition, texture, and sensory acceptance of frankfurter sausages. Six treatments were evaluated to test fat replacement: control (T0); low fat control (T1); low fat with 15% inulin (T2); low fat with 30% inulin (T3); low fat with 7.5% inulin and 7.5% pectin (T4); and low fat with 15% inulin and 15% pectin (T5). The addition of fibers increased the yield (T3 and T5; 98.96%), and the color parameters were slightly reduced (T3). Moisture (61.14%) and ashes (6.96%) of sausages with inulin and pectin were higher (T5), while shear force, hardness, fracturability, gumminess, and chewiness (T3 and T5) were slightly lower than those of the control. The addition of inulin (T2) increased the sensory acceptance of the sausages (5.75). Fat can be replaced with inulin and pectin in frankfurter sausages to produce healthy and functional products.

The inclusion of natural ingredients to preserve meat and meat products has increased in recent years. This study evaluated rosemary (REO) and garlic essential oils (GEO) as well as chipotle pepper oleoresin (CPO), alone or in combination, as preservatives on beef hamburgers (BH). Six treatments were evaluated: T1 (control, without additives), T2 (GEO 1%), T3 (REO 1%), T4 (CPO 0.5%), T5 (GEO 1% + CPO 0.5%) and T6 (REO 1% + CPO 0.5%). The microbiological quality, physicochemical characteristics, sensory evaluation, and lipid oxidation of hamburgers were evaluated. REO, GEO and CPO limited the growth of aerobic microorganisms, S. aureus, Salmonella spp., B. thermosphacta, moulds and yeasts, lactic acid bacteria and coliforms (p < 0.05); however, this effect depended on time. Furthermore, lipid oxidation decreased significantly (p < 0.5) in all treatments, except for T5 (GEO 1% + CPO 0.5%). Regarding sensory acceptance, consumers preferred BH with GEO in terms of colour, odour, flavour and overall appearance (p < 0.05). It is concluded that REO, GEO and CPO, alone or in combination, improve microbiological quality and inhibit the lipid oxidation of BH.

The current study was conducted to evaluate the dietary supplementation of Mexican oregano essential oil (MOO; Lippiaberlandieri Schauer) on broiler performance, carcass variables, meat quality, and sensory evaluation. One-day-old mixed-sex broilers were distributed in the following treatment groups, according to MOO supplementation levels: 0 = control diet; 200 = diet + 2200 mg of MOO/kg; 400 = diet + 4200 mg of MOO/kg; 600 = diet + 6200 mg of MOO/kg; 800 = diet + 8200 mg of MOO/kg; 1000 = diet + 1000 mg of MOO/kg. MOO affected (p<0.05) body weight, feed and water intake, and feed conversion ratio. The 200 and 400 mg/kg formulations gave better results at 7, 14 and 28 d than the other diets. MOO at 1000 mg/kg increased (p<0.05) slaughter weight and hot carcass yield, and decreased meat pH and cooking loss. The 200 and 400 treatments increased breast meat redness (a*), but reduced yellowness (b*). Meat hardness, cohesiveness and resilience were affected (p<0.05) by MOO, but not (p>0.05) the sensory parameters evaluated. Mexican oregano oil presents positive qualities as a plant-derived performance enhancer in broiler diets and improves of the meat quality of broilers at the levels of 200, 400 and 600 mg/kg of diet.

The addition prebiotics in broiler diets can benefit digestion and nutrient abortion. The objective of the present study was to evaluate the effects of moringa leaf powder and agave inulin on growth performance, intestinal morphology, and slaughter traits of broiler chickens over 40 d of grow-out. A total of 280 broilers (Ross 308) aged 1 d were randomly allocated to 4 treatments, with 7 replicates each and 10 chicks per replicate: T1 = control diet, T2 = control diet with 15 g/kg of moringa leaf powder, T3 = control diet with 15 g/kg of agave inulin, and T4 = control diet with 15 g/kg of moringa leaf powder and 15 g/kg of agave inulin. The results showed that analysis of treatments at time were not different (P > 0.05) for broiler weights, feed and water intake, and weight gain. Treatment was significant (P < 0.05) for feed efficiency at 22 to 40 d; the T4 group presented higher (P < 0.05) values, and the T1 group presented lower (P < 0.05) values. However, the villus lengths of intestinal sections were different (P < 0.05) among treatments. In the duodenum, jejunum, and ileum, villus lengths were highest (P < 0.05) in the T2 group and lowest (P < 0.05) in the T3 and T4 groups. Villus widths in the duodenum and ileum were highest (P < 0.05) in the T2 group, but the T1 group showed highest (P < 0.05) values in the jejunum sections. The T3 and T4 groups showed lowest (P < 0.05) values in villus width in the duodenum, jejunum, and ileum. Thigh yield was highest (P < 0.05) in the T2 group and lowest (P < 0.05) in the T4 group. The T1 group exhibited the highest (P < 0.05) piece yields for leg, wing, and hip-back. The T4 group showed lowest (P < 0.05) leg and wing yields. Moringa leaf powder and agave inulin at a concentration of 15 g/kg in diets did not affect broiler performance, whereas moringa leaf powder improved intestinal morphology and thigh yield, and agave inulin improved leg yield. The results demonstrated benefits of these 2 feed additives to improve intestine health and meat yield in broilers over a 40-day grow-out.

Feruloylated arabinoxylans obtained from nixtamalized maize bran were evaluated in terms of physicochemical characteristics and antioxidant capacity when incorporated in frankfurter sausages. Concentrations of 0.15% and 0.30% of feruloylated arabinoxylans were incorporated in frankfurter sausages formulations and a control without feruloylated arabinoxylans was also prepared. Shear force, hardness, color measurement, proximate analysis, pH, titratable acidity, water-holding capacity, total phenols, and antioxidant capacity were evaluated. Phenolic content and antioxidant capacity were significantly higher (P < 0.0001) in all treatments, sausages containing feruloylated arabinoxylans compared to the control. The results showed that there was a significant difference (P < 0.0001) in total phenolic content and antioxidant capacity with all feruloylated arabinoxylans sausages treatments higher than control. Additionally, significant differences (P < 0.0001) were obtained in the physicochemical parameters.
