Partial substitution of sodium chloride in Toscana sausages and the effect on product characteristics / Substituição parcial de cloreto de sódio em linguiça Toscana e os efeitos nas características do produto

High sodium intake has been linked with problems of hypertension and in Brazil, it still has above that recommended by the World Health Organization. Meat products contribute 2030% of sodium intake in the diet, indicating the necessity of reducing the amount of sodium added. The aim of this study was to reduce the sodium content in Toscana sausages by partial replacement of sodium chloride with PuraQ Arome NA4 substitute, and to evaluate the effect on physico-chemical and microbiological parameters and sensory acceptability. Three formulations one control (T1), and one with 20% (T2) and another with 30% (T3) sodium reduction compared with the control were produced. For comparative purposes, the physico-chemical, microbiological and sensory parameters were determined. In the proposed formulations with 20% and 30% reduction, the sodium contents were 857.3 mg 100 g-1 (T2) and 790.3 mg 100 g-1 (T3), compared with 926.7 mg 100 g-1 in T1. The produced samples were in accordance with the physico-chemical (moisture, lipid, protein and calcium) and microbiological (Salmonella, coagulase-positive Staphylococcus, and sulphite-reducing Clostridium and Coliforms at 45C) parameters stipulated by Brazilian law. The analysis of lightness and hue indicated that the sample T3 had a more intense red colour, while T1 had a less intense red colour. In the shear force evaluation, no difference...(AU)

O consumo elevado de sódio tem sido relacionado com problemas de hipertensão arterial e, no Brasil, ainda tem-se um consumo acima do recomendado pela Organização Mundial da Saúde. Os produtos cárneos têm contribuído com 20 a 30% do sódio ingerido na dieta, indicando a necessidade de redução no sódio adicionado. O objetivo do presente estudo foi reduzir o teor de sódio em linguiça Toscana por meio da substituição parcial do cloreto de sódio (NaCl) pelo substituto PuraQ Arome NA4 e avaliar o efeito deste aditivo na aceitação sensorial da linguiça Toscana. Foram elaboradas três formulações, uma controle (T1), uma com 20% (T2) e outra com 30% (T3) de redução de sódio, em comparação à primeira (T1). Para efeitos comparativos, os parâmetros físico-químicos, microbiológicos e sensoriais foram determinados. Nas formulações com proposta de 20% e 30% de redução, o teor de sódio foi 857,3 mg 100 g-1 (T2) e 790,3 mg 100 g-1 (T3), comparados com 926,7 mg 100 g-1 em T1. As formulações elaboradas atenderam os critérios físico-químicos (umidade, lipídio, proteína e cálcio) e microbiológicos (Salmonella, Staphylococcus coagulase positiva, Clostridium sulfito redutor e Coliformes a 45 ºC) estipulados na legislação brasileira. A análise dos parâmetros luminosidade e tonalidade cromática indicaram que a amostra T3 foi a de cor vermelha mais intensa, enquanto T1 a de cor vermelha menos intensa...(AU)

Food additives reduce lactic acid bacterial growth in culture medium and in meat products, increasing product shelf life / Aditivos alimentares reduzem o crescimento de bactérias láticas em meio de cultura e em produtos cárneos, promovendo acréscimo da vida útil

The uncontrolled growth of lactic acid bacteria (LAB) in meat and meat products leads to product spoilage, and thus shortens product shelf life. Although food additives are known to decrease LAB growth, this effect has not been analyzed in detail. Here, a detailed analysis was performed of the effects of sodium chloride, sodium polyphosphate, sodium lactate, sodium nitrite/nitrate, and garlic on the growth of the Lactobacillus plantarum in culture medium. The results were used to design and test experimental formulations of meat products. Initially, the effect of food additives on L. plantarum was evaluated using a Fractional Factorial Design (FFD), followed by a Central Composite Rotatable Design (CCRD). The Modified Gompertz Model was adjusted to the growth curves to determine the Kinetic parameters of bacterial growth (logarithmic increase in the population, specific growth rate, and lag phase extension). Higher sodium lactate and sodium chloride levels had a negative impact on L. plantarum growth parameters (p?0.05). Therefore, we designed experimental formulations of mortadella and smoked pork sausages containing 4% sodium lactate (w w-1) and 2.4-3.5% sodium chloride (w w-1), and determined LAB growth from samples of stored products produced according to these formulations, in order to determine product shelf life. There was an increased lag phase of LAB growth for most...(AU)

O rápido crescimento de bactérias láticas (BAL) em carnes e produtos cárneos leva a deterioração, reduzindo sua vida útil. Embora os aditivos alimentares sejam conhecidos por diminuir o crescimento de BAL, este efeito não tem sido avaliado especificamente. Neste trabalho, foi realizada uma análise detalhada dos efeitos do cloreto de sódio, polifosfato de sódio, lactato de sódio, nitrito/nitrato de sódio e alho no crescimento de Lactobacillus plantarum, em meio de cultura. Os resultados foram utilizados para desenvolver e testar experimentalmente formulações de produtos cárneos. Inicialmente, o efeito dos aditivos alimentares sobre o crescimento de L. plantarum foi avaliado utilizando um Delineamento Fatorial Fracionário (DFF), seguido por um Delineamento Composto Central Rotacional (DCCR). O modelo de Gompertz Modificado foi ajustado às curvas de crescimento para determinar os parâmetros de cinetica de crescimento bacteriano . Níveis superiores de lactato de sódio e cloreto de sódio promoveram a diminuição dos parâmetros de crescimento para o L. plantarum (p?0,05). Foram desenvolvidas formulações de mortadela e linguiça suína defumada, contendo lactato de sódio 4,0% (w/w) e cloreto de sódio 2,4 3,5% (w/w). Em seguida, as mesmas foram armazenadas para o acompanhamento da vida útil pela contagem de BAL. Observou-se um aumento na duração da fase lag das formulações avaliadas...(AU)

Characterization of the spoilage lactic acid bacteria in "sliced vacuum-packed cooked ham".

The lactic acid bacteria are involved with food fermentation and in such cases with food spoilage. Considering the need to reduce the lactic acid bacteria growth in meat products, the aim of this work was to enumerated and investigated the lactic acid bacteria present on sliced vacuum-packed cooked ham stored at 4 °C and 8 °C for 45 days by phenotypic and molecular techniques. The quantification showed that the lactic acid bacteria were present from the first day with mean count of 1.98 log cfu/g for the four batches analyzed. The lactic acid bacteria grew rapidly on the samples, and plate counts around 7.59 log cfu/g and 8.25 log cfu/g were detected after 45 days of storage at 4 °C and 8 °C, respectively; storage temperatures studied showed significant influence on the microorganism in study growth. The predominant lactic acid bacteria associated with the spoilage samples at one day of storage includes Lactobacillus sp., the phenotypic overlap Leuconostoc / Weissella sp. and Enterococcus sp. At 45 days of storage at 4 and 8 °C the mainly specie was Lactobacillus curvatus , following by Lactobacillus sakei and Leuconostoc mesentereoides ; the Enterococcus sp. was not present in the samples.
