          Abstract

          The aim of this study was to develop and evaluate a chicken nugget formulation with partial substitution of the meat or fat by pea fibre. Three formulations were developed: Control (C) – commercial formulation, Fibre Less Meat (FLM) – reduction of 10% of meat and addition of 2% of pea fibre and Fibre Less Fat (FLF) – reduction of 10% of fat and addition of 2% pea fibre. The products were characterized for their pH value, instrumental colour, texture, cooking loss (frying), proximate composition, and sensory properties (acceptance test). The control treatment presented lower (p<0.05) pH values compared to FLM and FLF. The analysis of cooking loss showed no differences (p>0.05) amongst the treatments. The texture analysis showed no significant differences amongst the treatments for elasticity and cohesiveness, although the FLF batch was firmer than the others (p<0.05). Regarding the sensory acceptance test, the consumers detected no differences (p>0.05) amongst the three treatments for aroma, texture, flavour or overall acceptability. One can conclude that it is possible to partially replace meat and fat by pea fibre in chicken nuggets, without compromising most of the physicochemical characteristics and without altering the sensory acceptance.

          Esse trabalho foi desenvolvido para avaliar nuggets de frango com substituição parcial de carne e gordura por fibra de ervilha. Foram utilizados três tratamentos: Controle (C) – formulação semelhante à comercial; Fibra/ Menos Carne (FMC) - redução de 10% de carne e adição de 2% de fibra de ervilha; e Fibra/ Menos Gordura (FMG) – redução de 10% de gordura e adição de 2% de fibra de ervilha. Os produtos foram caracterizados quanto ao pH, cor objetiva, perfil de textura, perda de peso após a fritura, composição centesimal e avaliação sensorial (teste de aceitação com escala hedônica de nove pontos). O tratamento Controle apresentou menor valor de pH em relação aos tratamentos FMC e FMG (p < 0,05). A avaliação da porcentagem de perdas após a fritura não apresentou diferença (p > 0,05) entre os tratamentos. Quanto à avaliação de textura, a elasticidade e a coesividade não diferiram (p > 0,05) entre os tratamentos, mas o tratamento FMG apresentou maior dureza em relação aos demais (p < 0,05). Em relação à avaliação sensorial, os consumidores não detectaram diferenças (p > 0,05) entre os três tratamentos para o aroma, a textura, o sabor e a aceitabilidade geral. Pode-se concluir que é possível a utilização de fibra de ervilha, como um substituto parcial de carne e gordura em nuggets de frango, sem prejuízos à maioria das características físico-químicas e sem alterações na aceitação sensorial.

            Utilization of cereal and fruit fibres in low fat dry fermented sausages.

            The effect of addition of cereal and fruit dietary fibres on the sensory properties of reduced-fat, dry fermented sausages was studied. Dry fermented sausages with 6 and 10% pork backfat were manufactured, with addition of cereal (wheat and oat) and fruit (peach, apple and orange) dietary fibres, at 1.5 and 3% concentrations. The energy value reduction of the final products was close to 35% and their final fibre contents, after ripening, were 2 and 4%, respectively. The ripening process was monitored by physico-chemical and microbiological analysis. Sensory properties were analyzed using triangular and hedonic tests and, a texture profile analysis was carried out. A correlation principal component analysis was performed. The results showed that the sensory and textural properties of batches with 3% dietary fibre were the worst, due to their hardness and cohesiveness. The best results were obtained with sausages containing 10% pork backfat and 1.5% fruit fibre especially those with orange fibre, which gave organoleptic characteristics similar to conventional high fat products. Thus, reduced fat sausages fortified with dietary fibre can be obtained with an acceptable sensory profile.
