Summary: Elderberry juice concentrate is rich in polyphenols, including anthocyanins and flavonols, which have various health-promoting properties. This study found that storage at room temperature led to a decline in anthocyanin content and an increase in polymeric color values. Storage at 5 degrees C had less impact on the contents of anthocyanins and chlorogenic acid. Overall, the antioxidant activity of elderberry concentrates remained stable over seven months of storage.

Summary: The concentrations of bioactive compounds in orange juice are affected by different citrus scion/rootstock combinations. Packaging and storage can optimize the shelf life of freshly squeezed juice. The combination of 'Rubi' orange in both 'Rangpur' lime and 'Swingle' citrumelo rootstocks showed higher concentrations of ascorbic acid and dehydroascorbic acid. Overall, scions grafted onto 'Swingle' citrumelo rootstock had higher concentrations of ascorbic acid, dehydroascorbic acid, and some phenolic compounds. Phenolic compounds had the highest concentrations at the time of fruit extraction and decreased during storage. Dark packaging increased the levels of bioactive compounds in juices stored for longer periods. These findings can help diversify scion/rootstock cultivars to produce pasteurized orange juice with higher nutritional value.

Summary: This study evaluated the effects of commercial postharvest storage (CPS) on the technological, physicochemical, and functional properties of carioca beans, finding that storage time affected the pH and acidity of the beans, with MP beans showing better physicochemical properties than PO beans. Glycosylated kaempferol was suggested as a possible chemical marker to differentiate the aging of PO and MP beans. Besides technological differences, storage was able to prevent physicochemical and functional alterations of beans.

Summary: This study evaluated the antioxidant activity and inhibition of targeted digestive enzymes of original smoothies made from strawberry tree fruit puree and apple juice enriched with various fruits. The results showed that the addition of certain fruits increased the antioxidant activity and ability to scavenge reactive oxygen species. The smoothies also exhibited inhibitory activity on alpha-amylase and alpha-glucosidase. The total polyphenol content ranged between 535.75 mg/100 g fw and 635.96 mg/100 g fw, with Acca sellowiana providing the highest amount. Flavan-3-ols were the dominant phenolic compounds, while only smoothies enriched with Crocus sativus showed a high amount of anthocyanins. These original smoothies have potential as nutraceuticals due to their favorable antioxidant compound profile.

Summary: In this study, original smoothies made with persimmon fruit puree and apple juice, enriched with Arbutus unedo fruits, Myrtus communis purple berry extract, Acca sellowiana, and Crocus sativus petal juice, were evaluated for their polyphenol composition, antioxidant activity, and inhibition on digestive enzymes over six months of storage. The results showed a decrease in polyphenol content, especially anthocyanins, and antioxidant activity during storage. The inhibitory activity on digestive enzymes, particularly a-glucosidase and pancreatic lipase, was also negatively affected by time storage. It is recommended to develop appropriate storage strategies to preserve the properties of these smoothies.
