Background: The objective of the present work was to study the effect of high-power ultrasound (HPU) on the microflora, enzymes and some quality attributes of a strawberry drink and to provide a theoretical basis for strawberry drink processing conducive to the development of more nutritious and healthier strawberry drinks.
Results: Fresh strawberry drink was subjected to HPU treatment at 20 kHz (242, 605 and 968 W cm ) for 2, 4, 6, 8 and 10 min in an ice bath. Results showed that polyphenol oxidase (PPO), pectin methyl esterase (PME) and β-glucosidase activities were decreased by 44.90, 89.11 and 84.71% respectively at 968 W cm for 10 min. Lower L*, a* and b* values and higher browning degree (BD) were observed in HPU-treated samples, resulting in a significant increase in ΔE value (P < 0.05). HPU treatment caused loss of viscosity and turbidity, while total soluble solids (TSS) and pH of the strawberry drink were stable. Total phenol content and antioxidant capacity increased while anthocyanin content decreased compared with untreated samples. Total aerobic bacteria (TAB) and molds and yeasts (M&Y) were reduced by 2.07 and 1.13 log cycles respectively at 968 W cm for 10 min.
Conclusions: HPU can effectively achieve the effect of pasteurization and maintain the nutrients of strawberry drink. © 2018 Society of Chemical Industry.

Article Synopsis
- The study investigates the health, metabolic, and behavioral impacts of perinatal cannabidiol (CBD) exposure on female mice and their offspring into adulthood, highlighting the lack of research on this widely used supplement.
- Results indicate that maternal CBD exposure can negatively affect offspring survival and postnatal development, particularly in males, while also producing various sex-dependent metabolic and behavioral changes in adults.
- The findings suggest CBD exposure during pregnancy and lactation influences behaviors such as anxiety and obsessive-compulsive traits, with significant implications for understanding the safety and effects of CBD use during pregnancy.

Article Synopsis
- Fruit wine production from strawberries can extend their shelf life and increase their value, with different strawberry cultivars affecting the sensory quality of the wine.
- A study identified 1,028 volatile organic compounds (VOCs) in the juices and wines of four different strawberry cultivars and performed sensory analysis to evaluate flavor and aroma.
- The ZJ cultivar was found to have the highest sensory evaluation scores and alcohol content, suggesting it is the most suitable for fermentation compared to the other cultivars.

Article Synopsis
- Strawberry wine production can help address the challenges of concentrated harvesting periods and short shelf life of strawberries in China, but the best cultivars for fermentation need to be identified.
- This study analyzed four strawberry cultivars (Akihime, Sweet Charlie, Snow White, and Tongzhougongzhu) for their juice and wine characteristics, focusing on physicochemical properties, bioactive compounds, and volatile organic components (VOCs).
- The results indicated that cultivar Akihime (ZJ) showed the highest levels of VOCs and bioactive compounds, making it the most suitable choice for strawberry wine fermentation, and providing insights for improving raw material quality in wine production.

Article Synopsis
- Children are increasingly drinking plant-based milks, but their effects on growth and nutrition remain uncertain.
- A systematic review analyzed studies from various databases to evaluate how plant-based milk impacts the growth and nutrition of children ages 1-18.
- Findings indicated that children consuming plant-based milk tended to have lower BMI, height, and vitamin D levels compared to those drinking cow milk, while fortified soy milk could benefit bone health in some adolescents.
High-Pressure Processing of Fruit Smoothies Enriched with Dietary Fiber from Carrot Discards: Effects on the Contents and Bioaccessibilities of Carotenoids and Vitamin E.
Molecules

Institute of Nutritional Sciences, Friedrich Schiller University Jena, 07743 Jena, Germany.
The effects of high-pressure processing (HPP) (450 MPa/600 MPa/3 min) on the carotenoid and vitamin E contents of smoothies made from strawberry, orange juice, banana and apple, and the same smoothies enriched with dietary fiber from discarded carrots were compared. The contents and bioaccessibilities of these compounds were also evaluated over the course of 28 days at 4 °C. The application of HPP in the formulations significantly increased the contents of β-cryptoxanthin, α-carotene and β-carotene and retained the contents of lutein, zeaxanthin and vitamin E compared to untreated samples.
