Natural colorants improved the physicochemical and sensorial properties of frozen Brazilian sausage (linguiça) with reduced nitrite Scientia Agricola

ABSTRACT: The use of natural colorants in meat products can keep its coloring attractive as well as meet the demand from consumers interested in products that are healthier. Nitrite is added as a preservative to these products and it is also a precursor of the generation of a specifically desired color in meat products. However, its use has been associated with the development of certain kinds of cancer. The objective of this study was to evaluate the effect of reduced levels of nitrite in Brazilian sausage (linguiça) with natural colorants on the physicochemical and sensorial properties following frozen storage. Nine treatments were tested: 0.015 % nitrite (C150), 0.0075 % nitrite (C75) and 0 % nitrite (C0), 0.0075 % nitrite and 1.5 % microencapsulated...

Production of pigments in Alternanthera sessilis calli mediated by plant growth regulators and light Biological Sciences
Milech, Cristini; Lucho, Simone Ribeiro; Kleinowski, Alítcia Moraes; Dutra, Débora Barwaldt; Soares, Mariana Mühlenberg; Braga, Eugenia Jacira Bolacel.
Among the compounds produced by plants, pigments such as betalains have received attention from both food and pharmaceuticals industries. The Alternanthera sessilis species produces these pigments, though in small quantities, and so it is necessary to increase production. Thus, many studies use elicitors that are capable of triggering physiological or morphological responses in plants. The objective was to establish callus production in A. sessilis grown under different combinations of growth regulators and light qualities and to assess whether these factors can increase betalain and flavonoid production. Leaf and internodal explants in MS medium with different growth regulators were used to obtain calli, which were subsequently transferred to a betacyanin...
