The pink/reddish color meat products characteristic of cured meat without the curing salts is a meat industry demand to serve consumers who are looking for healthy foods with the usual sensory characteristics. This study aimed to obtain and characterize a hybrid dye and use it as a replacer for curing salt in the production of pink/red color in mortadella stored for 40 days. A layered zinc hydroxide salt (ZHN) was obtained by alkaline precipitation to immobilize and increase cochineal carmine stability, obtaining the hybrid dye (ZHN-carmine) by ion exchange in aqueous solution. The ZHN-carmine was subjected to ultrasound to increase color intensity and reduce the amount of application. ZHN, cochineal carmine and ZHN-carmine were characterized by X-Ray Diffraction, Fourier-Transform Infrared Spectroscopy, Thermogravimetric Analysis and Differential Scanning Calorimetry. The ZHN-carmine was used in the mortadella elaboration traditionally prepared with nitrite/nitrate and/or carmine. In the characterization it was observed that carmine dye was adsorbed on the lamellar compound surface and over the mortadella storage, it ensures a more stable pink/reddish color than the others product formulations. A more intense color with lower L* and higher a* values was observed for mortadella added of ZHN-carmine ultrasound-assisted. Therefore, the lamellar matrix adsorbed with cochineal carmine may a suitable and useful alternative to obtain the pink/reddish color characteristic of cooked meat products by applying a natural hybrid dye.

Poultry meat is the world's most widely produced animal protein, with an estimated 103,498 metric tons (ready-to-cook equivalent) production for 2020. The United States leads the poultry meat production, followed by China, Brazil, and the European Union (USDA, 2019). Lipid oxidation of meat and meat products limits their quality and acceptability. For the meat industry, lipid oxidation affects mainly mechanically deboned chicken meat (MDCM) since the mechanical deboning process is performed by grinding meat and bone together (Hrynets et al., 2011).MDCM lifespan (frozen at or below −18°) does not usually exceed 90 days (Gomes et al., 2003). MDCM rapid oxidation and quality reduction, even frozen, are caused by unsaturated fats, air

Devido ao crescimento populacional e consequente aumento da demanda por alimentos, há uma significativa expansão do mercado de embalagens. Assim, surgiu as embalagens ativas e inteligentes, com o intuito de melhorar a qualidade dos alimentos durante o armazenamento e diminuir o desperdício. As carnes e derivados são bastante perecíveis e susceptíveis a alterações microbianas, devido a isso, são altamente dependentes dos materiais de embalagens. Nesse contexto, este artigo fará uma revisão sobre as últimas inovações e tecnologias de embalagens e suas aplicações para carnes e seus derivados, com o intuito de diminuir as reclamações dos consumidores e implementar soluções de embalagens ativas e inteligentes para facilitar a cadeia produtiva destes produtos. As embalagens biodegradáveis estão ganhando espaço, bem como filmes e revestimentos comestíveis, por meio da incorporação de compostos ativos como antimicrobianos e antioxidantes, assim como fontes naturais de óleos essenciais ou extratos vegetais que se tornaram alternativas aos conservantes químicos adicionados as carnes. Para as embalagens inteligentes, há diversas pesquisas relacionadas à biossensores, a fim de melhorar o processo pelo desenvolvimento de novas tecnologias que são normalmente baseadas em diferentes dispositivos químicos, enzimáticos, microbiológicos, capazes de indicar desde à temperatura do produto até apresentar um histórico sobre condições de armazenamento e rastreabilidade, importantíssimo para a cadeia da carne.
