Uso de especiarias como aditivos naturais na produção de hambúrguer bovino

Abstract

O interesse da população pelo consumo de alimentos saudáveis, práticos e com maior durabilidade é cada vez mais frequente. Para atender a essa demanda, as indústrias de alimentos têm buscado trabalhar com ingredientes naturais, visando minimizar o uso de aditivos sintéticos. O estudo objetivou investigar se a inclusão de diferentes especiarias em hambúrguer bovino afeta o crescimento bacteriano, a oxidação lipídica e as características sensoriais dos produtos. Foram elaboradas 4 formulações de hambúrguer: controle (sem aditivos), açafrão (1%), gengibre (1%) e urucum (1%). Os produtos foram analisados quanto à contagem bacteriana total (CBT) nos dias 0, 7 e 15 (armazenamento a 4 °C) e 0, 15 e 60 (armazenamento a –30 °C) e quanto à rancidez, nos dias 0, 30 e 60 (armazenamento a –30 °C). A aceitação dos atributos sensoriais e a intenção de compra foram avaliadas com o uso de escalas hedônicas. Todos os hambúrgueres formulados com especiarias e mantidos a 4 °C apresentaram menor CBT que a formulação controle, enquanto que, para os armazenados a –30 °C, o mesmo ocorreu apenas com os que continham gengibre. Menores valores de oxidação lipídica foram encontrados nas formulações contendo as especiarias, com 0, 30 e 60 dias de armazenamento a –30 °C. As formulações controle e gengibre lideraram a aceitação dos provadores nos atributos aparência e cor, enquanto que, para os demais atributos, não houve diferença entre as formulações com especiarias. Na intenção de compra, tanto os hambúrgueres formulados com gengibre como os do grupo controle despertaram maior interesse por parte dos provadores. Concluiu-se que a adição das especiarias reduziu a CBT e retardou a oxidação lipídica dos hambúrgueres, e que os produtos elaborados com gengibre apresentaram os maiores índices de aceitação sensorial e intenção e compra.

The population's interest in consuming healthier, more practical and durable foods is increasingly frequent. In order to meet this demand, the food industry has sought to work with natural ingredients in order to minimize the use of synthetic additives. The study aimed to investigate if the inclusion of different spices in bovine burger affects bacterial growth, lipid oxidation and sensorial characteristics of the products. Four hamburger formulations were prepared: control (without additives), saffron (1%), ginger (1%) and annatto (1%). The products were analyzed for total bacterial count (TBC) on days 0, 7 and 15 (storage at 4 °C) and 0, 15 and 60 (storage at -30 °C) and, for rancidity, on days 0, 30 and 60 (storage at -30 °C). The acceptance of the sensory attributes and the purchase intent were evaluated using hedonic scales. All burgers formulated with spices and kept at 4 °C had lower TBC than the control formulation, whereas for those stored at -30 °C, the same occurred only with the ginger-made ones. Lower lipid oxidation was found for the formulations containing the spices, with 0, 30 and 60 days of storage at -30 °C. Control and ginger formulations led the acceptance of the tasters for the attributes appearance and color, while for the other attributes no differences among the formulations with spices were detected. In the purchase intention trial, both the ginger-made and the control group burgers aroused greater interest from the tasters. It was concluded that the addition of spices reduced TBC and delayed the lipid oxidation of hamburgers, and that the products elaborated with ginger had the highest sensory acceptance and purchase intention indexes.
