Effect of increased acidity on the carotenoid pattern and colour of orange juice

European Food Research and Technology, 2009
The colour of orange juices is one of the main factors related to their acceptability. Their colour is mainly due to carotenoids, with the particularity that the major ones, the epoxycarotenoids, can isomerise into differently coloured isomers in the presence of acid.

The curious case of the orange coloured tonsils

International Journal of Pediatric Otorhinolaryngology, 2014
Tangier disease is an extremely rare and severe form of high density lipoprotein deficiency. Even though there is no specific therapy for patients with Tangier disease, it is important to recognize the clinical presentation as patients are at an increased risk of developing atherosclerosis and subsequent CVD.

Hormonal control of colour changes in orange peel

Experientia, 1969
Des quantites tres faibles d'acide gibberellique (6×10−4 μg/cm2) produisent pendant plusieurs semaines une inhibition de la coloration naturelle de la peau d'oranges vertes detachees. Des resultats semblables ont ete obtenus avec une cytokinine. L'inhibition produite par la gibberelline peut etre levee par l'ethylene.

Colour and carotenoid changes of pasteurised orange juice during storage

Food Chemistry, 2015
The correlation of carotenoid changes with colour degradation of pasteurised single strength orange juice was investigated at 20, 28, 35 and 42°C for a total of 32 weeks of storage. Changes in colour were assessed using the CIELAB system and were kinetically described by a zero-order model.

Yellow or orange colouration

2020
This chapter discusses yellow or orange discolouration of the skin, which is uncommon in children. It can occur due to accumulation of carotene in the skin, usually from infant diets containing too much carotene. Rarely, metabolic causes such as chronic renal failure or xanthomas are a cause.

Investigation of characteristic colour stability of powdered orange

Food Chemistry, 2000
The paper presents stability investigations of characteristic colour of powdered orange used for juice production. The colour of packed products darkens during the 12-month storage. In the same period, changes of characteristic wavelength are cyclical.

In vivo cytogenetic studies on mice exposed to Orange G, a food colourant

Toxicology Letters, 1988
Orange G, a monoazo dye, used as a food colourant, was evaluated with in vivo cytogenetic assays to determine its genotoxicity. Swiss albino male mice were exposed to Orange G through intraperitoneal injections. Bone marrow cells isolated from femora were analyzed for sister chromatid exchanges (SCE) and chromosome aberrations.

Short-term peroral toxicity of the food colour orange RN in pigs

Toxicology, 1973
Abstract Orange RN (monosodium salt of 1-phenylazo-2-naphthol-6-sulphonic acid) was fed to pigs at dietary levels of 160, 40, 10 and 0 (control)_mg/kg body weight/day for 15 weeks. In the 160-mg group hepatosis with liver enlargement, fibrosis and bile-duct proliferation was observed.
