Regular consumption of fresh orange juice increases human skin carotenoid content
2015
Dermal carotenoids are a good indicator of antioxidant status in the body. This study aimed to determine whether regular consumption of orange juice could increase dermal carotenoids. Two types of orange juice, obtained from regularly (CI) and partially (PRD) irrigated trees, were tested to reveal any possible association between juice and dermal carotenoids. Soluble solids, titratable acidity, and total carotenoids were quantified in the juice; skin carotenoid score (SCS) was assessed by Raman spectroscopy. Carotenoid content was 7.3% higher in PRD than in CI juice, inducing no difference in SCS. In a first trial with daily juice intakes for 25 days, SCS increased linearly (10%) in the ind…
The use of MAP for maintaining quality of ‘Bifara’ fig fruits
2021
Bifara is an old cultivar of Sicilians breba fig (Ficus carica L.). Several studies on market trends and consumer preferences show that fresh fruit is required to have a good visual appearance and to be without defects on the skin in order to be considered fresh and healthy. Breba fig is a climacteric fruit that ripens very rapidly, and therefore, once harvested, it must be kept under low temperature. To reduce the respiration rate of this fruit and increase its postharvest life, effectiveness of low temperature storage was studied on ‘Bifara’ fig fruit, either placed in Modified Atmosphere Packaging MAP (20 kPa O2 and 15 kPa CO2) bags and stored for 3, 5, 7, and 10 days at 5°C and 90% RH. …
Alginate-based coatings charged with hydroxyapatite and quercetin for fresh-cut papaya shelf life
2022
In this study, the effect of alginate-based coatings charged with quercetin glycoside compounds and hydroxyapatite/quercetin glycoside compounds (HA/QUE) on the microbiological quality, and on bioactive compounds of fresh-cut papaya, was evaluated for 14 days at 6 degrees C. Alginate coatings with hydroxyapatite/quercetin showed a high capability to slow down the growth of all microbiological parameters investigated. At the end of cold storage, the total bacteria count in papaya samples covered with HA/QUE alginate coating was 4.8 log CFU g(-1) which is significantly lower (P < 0.05) than 8.3 log CFU g(-1) for uncoated samples. Total carotenoids' percentage decrease, at the end of storag…
