A novel and enhanced approach for the assessment of the total carotenoid content of foods based on multipoint spectroscopic measurements
(Elsevier, 2011-06-15)
We have devised a more sensible approach to estimate the carotenoid content of orange juices, which can be regarded as a model system of food with intricate carotenoid pattern. For this purpose spectroscopic information ...

Color of orange juices in relation to their carotenoid contents as assessed from different spectroscopic data
(Elsevier, 2011-09)
The color of orange juice influences consumers' choice, hence much importance has been given to the assessment of this attribute for decades. The instrumental measurement of orange juice color can be harnessed for the ...

In vitro antioxidant capacity of tomato products: Relationships with their lycopene, phytoene, phytofluene and alpha-tocopherol contents, evaluation of interactions and correlation with reflectance measurements
(Academic Press Inc., 2016)
Tomato products were analysed for their carotenoids and a-tocopherol contents to study the contribution of individual compounds to the antioxidant capacity and assess the existence of interactions. Besides, the applicability ...

Carotenoids and fat-soluble vitamins in horse tissues: a comparison with cattle
(Cambridge University Press, 2015)
Carotenoids are important for human health because of their provitamin A function among other biological actions. Their implication on consumer point of view of cattle products have been widely studied, but very little ...

Application of tristimulus colorimetry to evaluate colour changes during the ripening of Colombian guava (Psidium guajava L.) varieties with different carotenoid pattern
(Wiley-Blackwell, 2011-04)
The pigment composition of three Colombian guava varieties, Regional roja, Regional blanca, and Palmira ICA-1, in unripe, turning and full ripe maturity stages was studied. Lycopene was identified as the major carotenoid ...

Bioaccessibility, antioxidant activity and colour of carotenoids in ultrafrozen orange juices: Influence of thawing conditions
(Elsevier, 2013-10)
Ultrafrozen orange juices are produced to preserve the nutritional and sensory quality of the fresh juices. However the effects of the thawing conditions on the nutritional quality have been scarcely studied. To gain insight ...

Effects of β-cyclodextrin addition and farming type on vitamin C, antioxidant activity, carotenoids profile, and sensory analysis in pasteurised orange juices
(Wiley-Blackwell, 2011-08-11)
The effects of organic farming, pasteurisation and addition of β-cyclodextrin on the content of vitamin C, colour, carotenoids and antioxidant capacity of orange juices were studied. After pasteurisation at 98°C (20s) and ...

Industrial orange juice debittering: Impact on bioactive compounds and nutritional value
(Elsevier, 2013-05)
The impact of an industrial debittering process (DP) on nutritional and bioactive compounds in orange juice (OJ) was studied. The DP was aimed at removing bitter components in OJ by physical adsorption in a resin. The ...

Phytoene and Phytofluene Isolated from a Tomato Extract are Readily Incorporated in Mixed Micelles and Absorbed by Caco-2 Cells, as Compared to Lycopene, and SR-BI is Involved in their Cellular Uptake
(Wiley-Blackwell, 2018)
Scope: Absorption mechanisms of phytoene (PT) and phytofluene (PTF) are poorly known. The main objectives of the study are to measure their micellization and intestinal cell uptake efficiencies and to compare them to those ...

Isoprenoids composition and colour to differentiate virgin olive oils from a specific mill
(Elservier, 2018-03)
The objective of this work was verify if, based on the concentration of some key isoprenoids and the colour, olive oils from a specific mill could be differentiated from those from other mills by linear discriminant analysis. ...
