High hydrostatic pressure (HHP) is a non-thermal pasteurization technology for the enhancement of food products' safety and quality. The components of tomato juice can be affected by HHP processing. Little is known about the effects of HHP-processed tomato juice on the gut microbiome and metabolism. Here, we performed high-throughput sequencing and metabolomics profiling to determine the critical differences in gut microbiota structure and metabolic profiles in mice administered with HHP-processed tomato juice. Tomato juice administration significantly increased the gut bacterial alpha diversity and the relative abundance of Bacteroides. The mice administered with HHP-processed tomato juice were characterized by the enrichment of Bacteroidetes, , and compared with those administered with HTST-processed tomato juice. Moreover, HHP-processed tomato juice promoted SCFA levels, which were positively correlated with the enriched . Our results show that HHP-processed tomato juice may drive healthy gut microbes and metabolites.

Background/objectives: This study explores the significance of beetroot and tomato juices, two prominent health-promoting foods known for their rich nutrient content and bioactive compounds. The growing consumer awareness of the link between diet and well-being emphasizes the need for food producers to align their products with health-conscious preferences. The aim of this research was to assess the composition, color, and sensory attributes-specifically color, taste, and odor-of various commercially available beetroot and tomato juices and to evaluate their acceptability among consumers.

Article Synopsis
- * Key volatile compounds, including isobutyric acid and isovaleric acid, produced by various ACB species during spoilage, contribute to unpleasant odors in fruit juices, which negatively affect product quality.
- * The study indicates that ACB species previously deemed non-spoilage threats may actually pose risks to the juice, beverage, and dairy sectors, suggesting a need to update current identification methods for ACB control.

Article Synopsis
- This study investigates how different types and frequencies of beverage consumption relate to erectile dysfunction (ED) in American men, using data from the NHANES 2003-2004.
- The results showed that men who consume grape juice regularly (5 or more times a week) had a significantly lower likelihood of experiencing ED, especially in those over 40 years old.
- While grape juice was the most notable beverage linked to reduced ED prevalence, other beverages like tomato, orange, and soft drinks also showed initial correlations with ED.
Objective: The of study was to evaluate the biological effects occurring in the animal body in conditions of a regular consumption of bread with a combination of flaxseed and clarified tomato juice in its composition.
Methods: The animals (Soviet Chinchilla breed) were randomly distributed between six groups. Group 1 is intact animals.

Article Synopsis
- The study investigates how different types of fruit and vegetable consumption affect frailty in a large U.S. population, using data from the National Health and Nutrition Examination Survey from 2005-2020.
- Researchers used dietary recalls to measure fruit and vegetable intake and assessed frailty using a frailty index, employing various statistical methods to analyze the results.
- Findings indicate that higher daily intakes of specific fruits (especially citrus, melons, and berries) and dark green vegetables are associated with a lower risk of frailty, with notable effects observed in individuals under 60 years and females.
