The Antioxidant Capacity of Rosemary and Green Tea Extracts to Replace the Carcinogenic Antioxidant (BHA) in Chicken Burgers

The present study aimed to evaluate the effect of natural extracts (rosemary and green tea extracts) in frozen storage of chicken burgers. Chicken burger treatments were prepared as follows: control (CON), 20 mg BHA/kg (BHA20), 10 mg green tea extract/kg (GT10), 38 mg green tea extract/kg (GT38), 18.6 mg rosemary extract/kg (RO18), and 480 mg rosemary extract/kg (RO480). Analysis of physicochemical parameters, color, TBAR index, and sensory acceptance were performed at 0, 30, 60, and 120 days of storage at −18°C in burgers packaged in LDPE plastic bags. The addition of natural antioxidants did not affect (p>0.05) the color and physicochemical parameters of the chicken burgers. After 120 days at −18°C, the RO480 sample showed a TBAR index similar (p>0.05) to BHA20 (0.423 and 0.369 mg, resp.). Sensory acceptance did not differ (p>0.05) among the treatments throughout the storage period (p>0.05)

Influence of information on the acceptance and purchase intention of an irradiated food: a study with brazilian consumers

This study investigated the effect of information on the acceptability and purchase intention of an irradiated watercress salad and its non-irradiated counterpart among Brazilian consumers (N = 236). Both the irradiated and the non-irradiated products were fairly accepted (ratings about 6.0–7.0 in the hedonic scale). Significant effects (p ≤ 0.05) of gender, education, and age were also observed: acceptance and purchase intention was lower among male participants who received both information and an identified irradiated product, and higher among female participants who received only information about the process. Adults (30–39 years old) were more critical, and the higher the educational level, the lower the acceptability and purchase intention ratings. Brazil is one of the major irradiators in the world, but there is still a lack of consumer studies focusing the acceptability of irradiated foods. So the findings presented herein would favor Brazilian producers and regulators to develop effective communication strategies and to promote the irradiation technology21358374COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informação04/10089-
