Development of food-grade bigels based on κ-carrageenan hydrogel and monoglyceride oleogels as carriers for β-carotene: Roles of oleogel fraction

, 2020
Bigels based on κ-carrageenan hydrogel and monoglyceride oleogels were developed as carriers for lipophilic bioactives. Bigels were prepared by mixing the hydrogel and oleogels under temperature control, and the roles of oleogel fraction in the ...

CRISPR/Cas9 directed editing of lycopene epsilon-cyclase modulates metabolic flux for β-carotene biosynthesis in banana fruit.

Metabolic Engineering, 2020
Banana is one of the most economically important fruit crops worldwide. Genetic improvement in banana is a challenging task due to its parthenocarpic nature and triploid genome.

Chitosan hydrochloride/carboxymethyl starch complex nanogels stabilized Pickering emulsions for oral delivery of β-carotene: Protection effect and in vitro digestion study.

Food Chemistry, 2020
β-Carotene was encapsulated in the Pickering emulsions stabilized by chitosan hydrochloride - carboxymethyl starch (CHC-CMS) nanogels. During ultraviolet radiation and storage, the retention of β-carotene in Pickering emulsions was higher than that of ...

Production of β‐carotene in Saccharomyces cerevisiae through altering yeast lipid metabolism

Biotechnology and Bioengineering, 2021
Saccharomyces cerevisiae is a widely used cell factory for the production of fuels and chemicals. However, as a non‐oleaginous yeast, S. cerevisiae has a limited production capacity for lipophilic compounds, such as β‐carotene.

The biosynthesis of carotenes

Archives of Biochemistry and Biophysics, 1962
Abstract A body of factual information has accumulated during the past decade which, in general, supports or is compatible with the proposal of Porter and Lincoln on the mechanism of biosynthesis of carotenes. However, some information has been obtained which necessitates a revision in details of the proposed scheme.

THE PYROLYSIS OF CAROTENE

Canadian Journal of Research, 1948
Kuhn and Winterstein reported the isolation of 2,6-dimethylnaphthalene from the products of pyrolysis of carotenoid pigments. The production of alkyl derivatives of phenanthrene and chrysene by the same type of cyclization can readily be formulated.

Encapsulation of β-carotene in wheat gluten nanoparticle-xanthan gum-stabilized Pickering emulsions: Enhancement of carotenoid stability and bioaccessibility

Food Hydrocolloids, 2019
β-carotene was encapsulated in Pickering emulsions stabilized by biopolymer particles formed by wheat gluten nanoparticles (WGN) or wheat gluten nanoparticle-xanthan gum (WGN-XG) complexes. The WGN-XG emulsions had larger initial mean particle diameters (

Formation of Carotene in vitro

Nature, 1960
RESULTS presented in this communication indicate that both β-hydroxy β-methylglutarate and mevalonate may be considered precursors of carotene formation in an in vitro extract obtained from mycelial mats of the mould Phycomyces blakesleeanus. This extract, capable of synthesizing carotene, can also be used for establishing the existence of a back ...
