Antioxidative effect of dietary Camelina meal in fresh, stored, or cooked broiler chicken meat

Abstract

Camelina sativa is an oilseed crop of the Brassica (Cruciferae) family that has gained increased popularity as a biofuel source. The present study was conducted to investigate the effects of feeding C. sativa meal to broiler birds on phenolic compounds, tocopherols, flavonoids, antioxidant capacity, and lipid peroxidation in chicken thigh meat during short (4°C for 2 or 7 d) or long-term (-20°C for 90 d) storage and cooking. One hundred sixty 1-d-old Cobb chicks were fed a corn-soybean meal-based diet with added Camelina meal at 0% (control), 2.5% (CAM2.5), 5% (CAM5), and 10% (CAM10). The experimental diets were fed for a period of 42 d. Feeding Camelina meal at 5 or 10% led to a 1.6-fold increase in γ-tocopherols in the thigh meat when compared with control birds (P < 0.05). No effect of diet on γ-tocopherols in the breast meat and α-tocopherols in the thigh and breast meat was observed (P > 0.05). Antioxidant activity measured as 2,2-azino-bis [3-ethylbenzo-thiazoline-6-sulfonic acid] radical scavenging capacity in the thigh meat from CAM2.5, CAM5, and CAM10 was higher than control birds (P < 0.05). In the breast meat, 2,2'-azino-bis (3-ethylbenzo-thiazoline-6-sulfonic acid) diammonium salt radical scavenging capacity was highest in CAM10 (P < 0.05). Feeding Camelina meal at 5 or 10% led to reductions in thigh TBA reactive substances (TBARS) during short-term (2 d) and long-term storage (P < 0.05). The TBARS of thigh meat from CAM5 and CAM10 were reduced up to 49 or 36% during 2- or 90-d storage, respectively, when compared with control (P < 0.05). However, no effect of diet on thigh meat TBARS at 7 d of storage was observed among treatment groups. Overall, TBARS were highest in the thigh meat from control and CAM2.5 birds (P < 0.05). Upon cooking, TBARS were lowest in thigh meat from CAM10 birds, which was over 48% lower than in meat from birds fed the control diet (P < 0.05). The current study showed that Camelina meal could be effective in inhibiting lipid oxidation and enhancing antioxidant capacity. However, the effect was more prominent in the thigh than breast meat.

The influence of dietary supplementation with <i>Melissa officinalis</i> and combination of <i>Achillea millefolium</i> and <i>Crataegus oxyacantha</i> on oxidative stability of stored poultry meat

“…Since the fat content in breast muscles is significantly lower than in thigh muscles (Aziza et al, 2010), the oxidative damage in frozen samples is lower in breast than in thigh muscles. The obtained results show that the amount of MDA in experimental groups was lower than in the control group (P<0.05) after one month of storage.…”

“…Thigh meat is higher in lipids and triglycerides and more prone to lipid oxidation than breast meat (Aziza et al, 2010). When comparing oxidative damage of breast and thigh muscles during storage under freezing conditions (12 months), we may conclude that oxidative damage of lipids was significantly lower in breast than in thigh muscle.…”

Effect of adding prefermented cereal product containing gamma-linolenic acid to broiler feed on production indicators and fatty acid profile of chicken breast

“…However, beside the positive impact on the fatty acid profile, some negative effects on growth indicators (lower gains, final weight, decreased feed conversion) appeared due to the antinutritive substances in these oil-rich plants (Aziza et al 2010). During solid state fermentation the fungus Thamnidium elegans produces enzymes necessary for hydrolysis of sources bound in biopolymers.…”
