Evaluation of the oxidative stability of Chipotle chili (<em>Capsicum annuum</em> L.) oleoresins in avocado oil

Abstract: Capsicum annuum L. (Chipotle chili) is a natural source of bioactive metabolites with antioxidant properties. The objective of this research was to obtain and characterize the oxidative stability under storage of Chipotle chili oleoresins extracted with cold-pressed avocado oil. The most efficient conditions obtained to extract carotenoids and phenolic compounds were at 1:3 ratio (chipotle chili: avocado oil; w:v) at room temperature in darkness during 48 h. At the end of the harshest conditions (45 °C, 30 day… Show more

“…Isomerization and oxidation reactions are the main factors responsible for the color change of dried tomato and pepper pasta. The lycopene present in these pasta is a carotenoid that possesses several double bonds, being prone to isomerization and oxidation reactions during processing and storage, which promotes biological activity and color loss (Cerecedo‐Cruz, Azuara‐Nieto, Hernández‐Álvarez, González‐González, & Melgas‐Lalane, 2018; Mutsokoti et al., 2017).…”

“…The behavior of the oil under stronger conditions (45 °C, 30 days) showed the following characteristics: (1) the extracts were stable to lipid oxidation, with a Totox index total value of 27.34, (2) 85.6% of carotenoids were conserved, (3) 80.66% of the antioxidant activity was retained, and (4) there was a color change (ΔE) of 1.783. The oleoresins obtained by extraction with avocado oil can be considered as an economic and sustainable alternative for the extraction of carotenoids, with a good oxidative stability, compared with organic solvents [35].…”

“…The role of GEO, REO and CPO as food preservatives, due to their antimicrobial effect against pathogens and spoilage microorganisms, such as S. aureus , P seudomonas , B. thermosphacta and Salmonella , is well documented [ 18 , 23 , 89 ]. GEO has a great variety of compounds, such as enzymes, amino acids and minerals, that contribute to its antimicrobial activity [ 90 ].…”
