Microencapsulação do licopeno com ciclodextrinas

Abstract: Os carotenóides compõem um grupo de compostos responsáveis pelas cores amarela, laranja e vermelha de muitos alimentos de origem vegetal e alguns de origem animal. São também citados como responsáveis pela diminuição do risco de doenças como câncer e doenças cardiovasculares [16].Um sistema de duplas ligações conjugadas constitui o cromóforo responsável pelo poder corante dos carotenóides e, também pela sua atuação contra doenças degenerativas. No entanto, este mesmo sistema é causa da sua instabilidade, e a p… Show more

“…In any case, this option would result in extremely long reaction times and, therefore, a 1/0.0026 molar ratio was selected to accomplish the encapsulations. This result is in accordance with that published by Matioli and Rodriguez-Amaya (2003), which describe the employment of lycopene of purity similar to that used in the present work.…”

“…The purities of the Lyc extracts reported by Matioli and Rodriguez-Amaya (2003), Nunes and Mercadante (2004), and Liu et al (2010) were 97, 96 and 99 %, respectively. These values correspond to differences in the type of extraction, the number of extractions, the solvents used, and the number of crystallization steps, affecting the purity of the Lyc extract.…”

“…This loss can be explained by the chemical structure of b-carotene. While Lyc features conjugated double bonds in the same chain and the absence of a b-ionone ring, b-carotene features double bonds in b-ionone rings, causing it to become less reactive and more susceptible to isomerization and oxidation during storage than Lyc (Matioli and Rodriguez-Amaya 2003).…”

“…Trans‐β‐carotene was added to the cooled gelatinized starch paste in a ratio of 1:500 w/w, on dry starch basis. The ratio between the core and wall material was chosen based on other authors who encapsulated carotenoids (Matioli & Rodriguez‐Amaya, 2002, 2003; Loksuwan, 2007). The mixture was stirred until complete homogenisation for 15 min.…”
