In vivo evaluation of bone repair guided with biological membrane based on polyhydroxybutyrate and norbixin

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2021
AbstractThe present work aimed to synthesize and verify the effectiveness of the polyhydroxybutyrate and norbixin membrane as a scaffold in bone defects induced in the tibia of rats. Twenty‐four male Rattus norvegicus rats were used, divided into control and membrane groups.

Determination of bixin and norbixin in meat using liquid chromatography and photodiode array detection [PDF]

Food Additives and Contaminants - Part A Chemistry, Analysis, Control, Exposure and Risk Assessment, 2009
The development of an analytical method that enables routine analysis of annatto dye, specifically bixin and norbixin, in meat tissue is described. Liquid-solid extraction was carried out using acetonitrile. Analysis was by HPLC with photodiode array detection using two fixed wavelengths (458 and 486 nm). The possibilities of ion trap mass spectrometry

PROPERTIES OF BIXIN AND NORBIXIN AND THE COMPOSITION OF ANNATTO EXTRACTS

Journal of Food Science, 1971
SUMMARY— 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.

Digestive Stability and Transport of Norbixin, a 24-Carbon Carotenoid, across Monolayers of Caco-2 Cells [PDF]

Journal of Agricultural and Food Chemistry, 2010
Annatto is a natural pigment widely used in the food industry to add yellow to red colors to dairy and cereal products. Here, the in vitro bioaccessibility and potential bioavailability of norbixin, the abundant 24-carbon carotenoid in annatto, were investigated.

Prooxidant activity of norbixin in model of acute gastric ulcer induced by ethanol in rats

Human & Experimental Toxicology, 2015
Free radicals and oxidative stress play a central role in gastric injuries caused by ethanol (EtOH). Antioxidant strategies to counteract EtOH toxicity are highly desirable. Norbixin (NBIX) is a carotenoid with antioxidant potential largely used in the food industry.

Microencapsulation by Freeze-Drying of Potassium Norbixinate and Curcumin with Maltodextrin: Stability, Solubility, and Food Application

Journal of Agricultural and Food Chemistry, 2013
Stability of potassium norbixinate and curcumin by microencapsulation with maltodextrin DE20 and freeze-drying was evaluated as a function of exposition to light, air, different pH, water solubility, and in food applications. The best results were obtained with microencapsulated potassium norbixinate 1:20, which, when vacuum-packed and in the presence ...

Characteristics of Activated Carbon and Carbon Nanotubes as Adsorbents To Remove Annatto (Norbixin) in Cheese Whey

Journal of Agricultural and Food Chemistry, 2013
Removing annatto from cheese whey without bleaching has potential to improve whey protein quality. In this work, the potential of two activated carbon products and multiwalled carbon nanotubes (CNT) was studied for extracting annatto (norbixin) in aqueous solutions.

Nanoencapsulation of Bixin and Norbixin in Sodium Alginate: Preparation, Characterization, and Release in Food Simulant

Current Bioactive Compounds
Aims: Bixin and norbixin are natural antioxidants used as pigments in the food industry, but their chemical structure makes them susceptible to environmental factors (light, oxygen, and temperature). Background: Nanoencapsulation techniques can improve the stability and solubility of these compounds in addition to reducing particle size which can ...
