Effect of NaCl replacement on physicochemical and sensory properties of the traditional cured coppa
This study aimed to reduce sodium content in pork coppa without affecting consumer acceptance. NaCl reduction, partial replacement with KCl, and reduction in salting process time were evaluated. Six treatments were performed: Standard - 100% NaCl with a 2-day salting process and a 5-day re-salting process; T1 - a mixture of 70% NaCl/30% KCl; T2, T3, T4 - mixtures of 85% NaCl/15% KCl; T5 - 100% NaCl. T1 to T5 applied a 2-day salting process and a 2-day re-salting process. All treatments complied with Brazilian sodium guidelines. No statistically significant difference in consumer acceptance was observed. A reduction of 4 days in salting and re-salting processes maintained sensory characteristics and reduced sodium content by 50%. Even with reduced salt content, no changes in physicochemical parameters or effects on product preservation and microbiological quality were observed. NaCl reduction and replacement up to 30% KCl did not affect coppa characteristics or acceptance
Action of different agents on lipid oxidation of mechanically deboned chicken meat
ABSTRACT. Bigolin J., Weber C.I. & Alfaro A.T. [Action of different agents on lipid oxidation of mechanically deboned chicken meat.] Ação de diferentes agentes sobre a oxidação lipídica de carne mecanicamente separada de frango. Revista Brasileira de Medicina Veterinária, 36(4):383-388, 2014. Universidade Tecnológica Federal do Paraná, Campus Francisco Beltrão, Linha Santa Bárbara s/n, Caixa postal 135, Francisco Beltrão, PR 85601-970, Brasil. E-mail: [email protected] The study evaluated the effect of sodium chloride (1, 5%), sodium erythorbate (0,5% and 1,0%) and ascorbic acid (0,1% and 0,2%) in inhibition lipid oxidation in mechanically deboned chicken (CMS). Were determined the peroxide value, acidity, pH, color and odor of the samples on 1st, 3rd and 5th days. Treatments with sodium erythorbate and ascorbic acid had a significant influence (p≤0,05) on the peroxide value, acidity and pH. Ascorbic acid and erythorbate sodium especially, were effective in reducing lipid oxidation in mechanically deboned chicken
Efeito da substituição de NaCl nas propriedades físico-químicas e sensoriais de Copa curada tradicional
This study aimed to reduce sodium content in pork coppa without affecting consumer acceptance. NaCl reduction, partial replacement with KCl, and reduction in salting process time were evaluated. Six treatments were performed: Standard - 100% NaCl with a 2-day salting process and a 5-day re-salting process; T1 - a mixture of 70% NaCl/30% KCl; T2, T3, T4 - mixtures of 85% NaCl/15% KCl; T5 - 100% NaCl. T1 to T5 applied a 2-day salting process and a 2-day re-salting process. All treatments complied with Brazilian sodium guidelines. No statistically significant difference in consumer acceptance was observed. A reduction of 4 days in salting and re-salting processes maintained sensory characteristics and reduced sodium content by 50%. Even with reduced salt content, no changes in physicochemical parameters or effects on product preservation and microbiological quality were observed. NaCl reduction and replacement up to 30% KCl did not affect coppa characteristics or acceptance.Este estudo teve como objetivo reduzir o teor de sódio em Coppa suína sem afetar a aceitação do consumidor. Foram avaliadas a redução de NaCl, a substituição parcial por KCl e a redução do tempo de processo de salga. Foram realizados seis tratamentos: Padrão - 100% NaCl com processo de salga de 2 dias e processo de re-salga de 5 dias; T1 - mistura de 70% NaCl/30% KCl; T2, T3, T4 - misturas de 85% NaCl/15% KCl; T5 - 100% NaCl. T1 a T5 aplicou-se um processo de salga de 2 dias e um processo de re-salga de 2 dias. Todos os tratamentos cumpriram as diretrizes brasileiras de níveis de sódio. Não houve diferença estatisticamente significativa na aceitação do consumidor. Uma redução de 4 dias nos processos de salga e re-salga manteve as características sensoriais e reduziu o teor de sódio em 50%. Mesmo com teor reduzido de sal, não foram observadas alterações nos parâmetros físico-químicos ou efeitos na preservação do produto e na qualidade microbiológica. A redução e substituição de NaCl até 30% KCl não afetaram as características ou aceitação do Coppa
Brazilian Flora 2020: Leveraging the power of a collaborative scientific network
International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
