Bixin-loaded colloidal nanodelivery systems, techniques and applications
Food Chemistry, 2023Bixin is the cis-carotenoid from the seed of achiote tree or annatto. It is an approved liposoluble apocarotenoid by FDA as colorant and additive in the food industry. Nonetheless, bixin is unstable in the presence of oxygen, light, high pHs (alkali) and heat; thereby reducing its bioavailability/bioactivity, and also, with a low solubility in water ...

Hydrophilization of bixin by lipase-catalyzed transesterification with sorbitol
Food Chemistry, 2018Bixin is one of the most used yellow-orange food colorants in the food industry. The polyene chain of bixin makes it highly hydrophobic and less suitable for water-based food formulations. Lipase-catalyzed reactions of bixin with sorbitol were studied to synthesize a new derivative of bixin with potential hydrophilic properties.

Aprotic solvents effect on the UV–visible absorption spectra of bixin
Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2014We describe here the effects of aprotic solvents on the spectroscopic characteristics of bixin. Bixin was dissolved in dimethyl sulfoxide, acetone, dichloromethane, ethyl acetate, chloroform, dimethyl carbonate, cyclohexane and hexane, separately, and its spectra in the resulting solutions were determined by UV-visible spectrophotometry at normal ...

Model Studies on the Photosensitized Isomerization of Bixin
Journal of Agricultural and Food Chemistry, 2003The photosensitized isomerization reaction of the natural cis carotenoid bixin (methyl hydrogen 9'-cis-6, 6'-diapocarotene-6, 6'-dioate) with rose bengal or methylene blue as the sensitizer in acetonitrile/methanol (1:1) solution was studied using UV-vis spectroscopy, high-performance liquid chromatography (HPLC), and time-resolved spectroscopic ...

[Advances in the biosynthesis and application of bixin].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2021Since synthetic pigments are potentially harmful to human health, natural ones such as bixin, one of the carotenoids, are favored. As the second widely used natural pigment in the world, there is significant interest in the biosynthetic pathway of bixin which has not been fully elucidated.

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 ...
