“…Raybaudi-Massilia et al [31] observed that adding 0.2 % v/v malic acid (corresponding to 3.22 g malic acid L −1 of juice) to apple and pear juices inhibited S. Enteritidis's growth at 20 and 35 • C. We observed a significant decline in the populations of S. enterica strains in plum puree after 24 h of storage at the three evaluated temperatures, possibly due to its malic acid content being almost three times higher than the minimum inhibitory concentration (MIC) observed by Raybaudi-Massilia et al [31]. Black currant and blueberry purees, despite having the highest TPCs and antioxidant capacities, exhibited different Salmonella survival rates, possibly influenced by the varying phenolic compounds present in each puree [32]. The antimicrobial effect of other intrinsic factors, including phenolic compounds, have been studied in fruit and vegetable juices [32][33][34].…”

Salmonella enterica, known for its resilience to acidic environments, has been linked to foodborne outbreaks of illness from fruit derivatives. This study aimed to assess the survival of five serovars of Salmonella enterica subsp. enterica in various fruit purees subjected to different storage temperatures. Among the studied serovars, S. enteritidis exhibited the most significant population decrease in all fruit purees. In contrast, S. Agona, S. Gaminara, S. Michigan, and S. Montevideo survived in peach puree at 4 °C for at least 3 days, and S. Agona, S. Gaminara, and S. Montevideo maintained their initial levels in pear puree under the same time/temperature conditions. However, none of the strains were detectable in plum and black currant purees after 2 days at 4, 15, or 25 °C. These findings highlight variations in the behaviour of S. enterica serovars within different fruit purees. Likewise, low-temperature conditions prolonged the survival of the tested strains in all fruit purees analysed.

Flavonoids-Rich Plant Extracts Against Helicobacter pylori Infection as Prevention to Gastric Cancer

et al. 2022

View full text Add to dashboard Cite

Gastric cancer is the fifth most common and fourth type to cause the highest mortality rates worldwide. The leading cause is related to Helicobacter pylori (H. pylori) infection. Unfortunately, current treatments have low success rates, highlighting the need for alternative treatments against carcinogenic agents, specifically H. pylori. Noteworthy, natural origin products contain pharmacologically active metabolites such as flavonoids, with potential antimicrobial applications.Objective: This article overviews flavonoid-rich extracts’ biological and pharmacological activities. It focuses on using these substances against Helicobacter pylori infection to prevent gastric cancer. For this, PubMed and Science Direct databases were searched for studies that reported the activity of flavonoids against H. pylori, published within a 10-year time frame (2010 to August 2020). It resulted in 1,773 publications, of which 44 were selected according to the search criteria. The plant family primarily found in publications was Fabaceae (9.61%). Among the flavonoids identified after extraction, the most prevalent were quercetin (19.61%), catechin (13.72), epicatechin (11.76), and rutin (11.76). The potential mechanisms associated with anti-H. pylori activity to the extracts were: inhibition of urease, damage to genetic material, inhibition of protein synthesis, and adhesion of the microorganism to host cells.Conclusion: Plant extracts rich in flavonoids with anti-H. pylori potential proved to be a promising alternative therapy source, reinforcing the relevance of studies with natural products.

“…Besides, grapefruit or grapefruit juice is often recommended as a healthy dietary constituent, particularly in some weight reducing diets (Xiao & Hu, 2014). Furthermore, other authors reported many healthy benefits of grapefruit (Xu et al, 2007;Yin et al, 2012). In addition, its zest is exploited in the production of pectin and essential oils (Kimball, 1999).…”

<p>Very few studies were carried out to investigate the aphids attacking grapefruit. These pests cause considerable damages on citrus trees and other crops. This paper reports on the fluctuations of aphids on grapefruit in the region of Skikda (Algeria). From January 2012 to December 2013, monthly surveys were performed to measure the abundance of aphids recorded on 16 leaves of grapefruit. Through this study, five aphid species were identified, among them <em>Aphis spiraecola </em>Patch, 1914 was the most numerous. Besides, we noticed that the populations of aphids reached high levels many times within the year. However, the most important densities were recorded in spring and autumn.</p>
