Enzymatic esterification of bixin by l-ascorbic acid
Biotechnology Letters, 2000Bixin, a carotenoid, was esterified by l-ascorbic acid using immobilized lipase B from Candida antarctica. The conversion of l-ascorbic acid was 25% under atmospheric pressure. Ester production was twice higher when working under reduced pressure and was third lower when norbixin was used as a substrate-acyl donor due to lipase specificity, leading to ...

Bixin stimulates immune response in cats
The FASEB Journal, 2007Studies on its immune modulatory action is lacking. Female domestic cats (3 yr old) were fed daily for 16 wk with 0, 1, 5 or 10 mg bixin (n = 14/group). Blood was sampled on wk 0, 6, 12 and 16. All cats were then vaccinated with an attenuated polyvalent vaccine on wk 12 and 14. Skin hypersensitivity response (DTH) to saline, concanavalin A, the vaccine,

Bixin Action in the Healing Process of Rats Mouth Wounds
Current Pharmaceutical Biotechnology, 2014Oral lesions that manifest as ulcer lesions are quite common and can cause discomfort to the patient. Searching for drugs to accelerate the healing of these lesions is nonstop process. Bixin is a molecule found in annatto (urucum) seeds and is considered a viable therapeutic option to treat such lesions due to its anti-inflammatory, anti-oxidant, and ...

Biosynthesis of the Food and Cosmetic Plant Pigment Bixin (Annatto)
Science, 2003Bixin, also known as annatto, is a seed-specific pigment widely used in foods and cosmetics since pre-Columbian times. We show that three genes from Bixa orellana , native to tropical America, govern bixin biosynthesis.

Thermal Degradation Kinetics of Bixin in an Aqueous Model System
Journal of Agricultural and Food Chemistry, 2005The kinetics of the thermal degradation of the natural cis carotenoid bixin in a water/ethanol (8:2) solution was studied as a function of temperature (70-125 degrees C), using high-performance liquid chromatography. The curves for the decay of bixin and formation of products (e.g., di-cis and all-trans isomers and a C17 degradation compound) did not ...

PROPERTIES OF BIXIN AND NORBIXIN AND THE COMPOSITION OF ANNATTO EXTRACTS
Journal of Food Science, 1971SUMMARY— The melting point and 1 1% cm ‐values of a‐bixin, β‐bixin, and a‐norbixin were determined and the stability of a‐bixin examined under different conditions. The total pigment content of butter colors was determined.

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2005
Carotenoids are regarded as effective antioxidants, antimutagenic and anticarcinogenic agents. Annatto, a red-yellow extract obtained from seeds of Bixa orellana L. is a mixture of several carotenoids and one of them bixin (BXN), is known as its major coloring compound.

Effects of pH on the Molecular Binding between β-Lactoglobulin and Bixin
Journal of Agricultural and Food Chemistry, 2013Binding between β-lactoglobulin (β-Lg), the major whey protein, and bixin, the major carotenoid in annatto, was studied at pH 3.0-10.0. The Fourier transform infrared spectroscopy and UV-vis absorption spectroscopy results showed that the binding involved a complex formation. The tryptophan quenching fluorescence and analytical ultracentrifugation data

Uptake and immunomodulatory role of bixin in dogs.
Journal of animal science, 2016Carotenoids are readily absorbed from the diet and distributed in blood leukocyte subcellular organelles. Bixin, a potent bioactive found in the seed of the Annatto plant, , possesses antioxidant and anti-inflammatory properties. The purpose of this study was to determine the uptake of bixin by plasma, lipoproteins, and leukocytes in domestic dogs and ...
