Potatoes are a good source of carotenoids, which are lipophilic compounds synthesized in plastids from isoprenoids. The aim of this research was to determine the content of carotenoids in relationship with the colour of organically and conventionally cultivated potato genotypes before and after period of storage. In cooperation with the State Priekuli Plant Breeding Institute (Latvia), six pota...

a pot experiment was conducted to evaluate the effect of foliar spray of salicylic acid (0, 50, 100 ppm), ascorbic acid (0, 100, 200 ppm) and thiamine (0, 50, 100 ppm) on vegetative growth, flowering and photosynthetic pigments of marigold (calendula officinalis l.) plants at greenhouse of sb university of kerman, iran. results showed that application of salicylic acid and thiamine increased nu...

The objective of the present study was to determine content and bioaccessibility carotenoids in 104 maize hybrids available at market. Lutein, zeaxanthin, ?- ?-cryptoxanthin, ?-carotene were determined whole grains micelles produced during standardized INFOGEST digestibility analysis, their calculated as ratio micellar grain carotenoids. Tested varied total carotenoid content, with 34% having r...

Carrot, tomato and papaya represent important dietary sources of β-carotene and lycopene. The main objective of the present study was to compare the bioavailability of carotenoids from these food sources in healthy human subjects. A total of sixteen participants were recruited for a randomised cross-over study. Test meals containing raw carrots, tomatoes and papayas were adjusted to deliver an ...

Sexually selected traits like complex vocalizations or vibrant colors communicate reliable information about mate quality when they are costly to display. Although several general condition-dependent mechanisms underlying the acquisition of mating advertisements have been identified, we rarely know the precise physiological and molecular challenges that animals must meet to develop their sexual...

The aim of this study is to compare the production of biomass enriched with carotenoids and ergosterol by yeast strain Rhodotorula glutinis CCY 20-2-26 grown under optimal growth conditions and in the presence of exogenous stress factors. R. glutinis cells were exposed to UV irradiation, oxidative stress (2–10 mmol/L H2O2) and osmotic stress (2–10 % NaCl). During the experiment, growth characte...

Ataulfo’ mango (Mangifera indica L.) is one of the most produced and consumed fruits in Mexico. This mango cultivar is claimed as a good source of carotenoids, however, its carotenoid profile has not been determined. In addition, bioaccesibility and bioavailability of carotenoids from fresh mangoes have not been tested. The present work included three experimental sections. In the first section...
