A synergistic effect of Cu2+ and norbixin on DNA damage

Food and Chemical Toxicology, 2008
Annatto and its derivatives are members of carotenoids with long-chain conjugated polyenes, which are widely used as food additives and antioxidant. However, carotenoids can also act as pro-oxidant under certain circumstances. To explore the biochemical behavior of annatto and its derivatives, the DNA damage effects by norbixin to the copper(II) ions ...

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.

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.

Biodegradable sodium alginate films incorporated with norbixin salts

Journal of Food Process Engineering, 2020
AbstractPlastic packaging derived from petroleum may have a negative impact on the environment when it is not properly recycled. Some studies present the use of biodegradable packages developed from natural polymers as a sustainable alternative; thus, the present work aimed to develop biodegradable sodium alginate films with antioxidant properties by ...

Biodegradable packaging of cellulose acetate incorporated with norbixin, lycopene or zeaxanthin

Industrial Crops and Products, 2020
Abstract There is a growing interest in the use of biopolymers for the development of biodegradable packaging with the addition of natural compounds. The objective of this work is to develop cellulose acetate films with the addition of norbixin, zeaxanthin or lycopene, and to evaluate the physicochemical and barrier properties.

Incorporation of bixin in aqueous media: Self-formulation with sorbitol ester of norbixin

Food Chemistry, 2019
We have previously reported how the natural food colorant, bixin, was enzymatically modified by appending sorbitol to the bixin scaffold. The resulted product, sorbitol ester of norbixin (SEN) was expected to be more hydrophilic. The present study aimed to investigate the physical behaviour of SEN in aqueous media.

Study on the simultaneous determination of bixin and norbixin in foods by high-performance liquid chromatography

Heavy metals and arsenic concentrations in water, agricultural soil, and rice in Ngan Son district, Bac Kan province, Vietnam, 2023
Bixin and norbixin are two types of apocarotenoids that can be extracted from the seeds of cashew nuts (Bixa orellana). They are the main components of annatto, a natural food coloring agent, which is widely used in the food industry to impart yellow and orange-red hues to various food products.

Improving norbixin dispersibility and stability by liposomal encapsulation using the pH‐driven method

Journal of the Science of Food and Agriculture, 2021
AbstractBACKGROUNDNorbixin, a carotenoid extracted from annatto seeds, is widely utilized as a natural pigment in foods, cosmetics and medicines. Its water solubility is relatively high under neutral or alkaline conditions but low under acidic conditions, which limits its application in some food products.RESULTSThis problem was overcome by utilizing ...

Norbixin, a natural dye that improves serum lipid profile in rabbits and prevents LDL oxidation

Food Research International, 2022
We hypothesized that norbixin, which is a carotenoid used as an orange/red natural food coloring additive, has anti-atherogenic properties. An in vitro oxidation assay with human LDL and a rabbit model of atherosclerosis were used to test this hypothesis. Norbixin inhibited the oxidation of isolated human LDL in a concentration-dependent manner. In the
