This research evaluated the influence of phenolic compounds and flavonoids on the colour and antioxidant activity of M. beecheii honeys. Forty-three honey samples from different site located in the low deciduous forest of Yucatan, Mexico, were extracted during the harvest and post-harvest seasons (2020 – 2021). The Pfund method was used to measure colour, Folin-Ciocalteu method for phenols measurement, aluminum chloride method for flavonoids determination, and ABTS and DPPH IC50 assay to determine antioxidants. The predominant colour of the honey was extra light amber and light amber at both seasons. Phenols ranged from 780 to 1317 mg/kg GAE; flavonoids from 36 to 55 mg/kg CE and antioxidant were 675 to 1161 µmol/kg TEAC by the ABTS and 361.8 to 173.0 mg/mL by the DPPH IC50.  Phenols and flavonoids were correlated with colour and radical scavenging activity, indicating the influence of these compounds with the darker colour and higher antioxidant activity of honey. The statistically significant difference (P<0.05) between seasons could be associated with the botanical origin with great diversity of melliferous flora present in the low deciduous forest of the Yucatan Peninsula.   Keywords: Antioxidant; colour; flavonoids; honey; Melipona beecheii.","PeriodicalId":11648,"journal":{"name":"Emirates Journal of Food and Agriculture","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139161945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Durian seeds are often used by people as the main ingredient in making bread and cakes. However, the use of durian seeds as the main ingredient in making nata has never been done. Nata is extracellular cellulose obtained from the activity of the bacteria Acetobacter xylinum. The nata that is often found is nata de coco made from coconut water as the main ingredient. This research aims to look at the formation of nata de durio from durian seeds. The results showed that different dry weights of durian seeds did not affect the thickness of the Nata De Durio formed. The thickness of Nata De Durio on days 7 and 14 was highest at a dry weight of 250 grams of durian seeds with an average of 0.4 and 0.5 cm and the lowest was at a dry weight of 100 grams of durian seeds with an average of 0. 3 and 04 cm. Conclusion: The difference in dry weight of durian seeds does not affect the thickness of Nata De Durio.

Analyses for the phytochemical components of caper fruit used in the production of Tulum cheese showed that it has high levels of bioactive components in terms of antioxidant activity, total phenolics, and flavonoids. It was determined that C. spinosa, which is used in the production of Tulum cheese, had a good radical scavenging activity (DPPH radical assay). Four experimental groups were arranged in the present study and analyzed on the 1, 30, 45, 60, and 90th day of ripening. T_C was designed as the control group, T_C1, T_C2, and T_C4 groups contained 1, 2, and 4% of caper. According to the obtained results as the content of caper increased, dry matter ratios, ash, pH values, tyrosine and free fatty acid values in cheese increased significantly. The microbiological evaluation revealed that the caper affected positively Lactobacillus spp. counts. The highest aroma and taste scores among caper cheeses were given to the control group (T_C). Generally, caper did not have a negative effect on the textural profile of the product. These results revealed that C. spinosa contributes to the improvement of the bioactive potential as well as increasing the quality parameters of cheese.

Previously, we were obtained several endophytic bacterial strains that exhibited dual activity, one of which was Raoultella terrigena PCM8. This study aimed to characterize the ACCD and nitrogenase genes of PCM8 strain. The acdS gene was obtained from the results of Whole Genomic Sequencing analyis, while the nifH gene was obtained by PCR. The characterization of both of the genes was carried out by means of in-silico analysis. WGS annotation analysis, showed that the acdS gene of PCM8 was located at the locus 19090 of genomic DNA and contains 978 nucleotides. In silico analysis of both acdS and nifH gene products showed that the ACCD enzyme of PCM8 had 325 amino acids, with molecular weight of 34.95 kDa, while nitrogenase as represented by nifH subunit product consist of 96 amino acids with molecular weight of 93.98 kDa, respectively.  The ACCD had pI value of 5.06, and catalytic residues of Lys51, Ser78, Tyr287, and Thr288, while nifH gene product had the pI value of 11.77. The results suggested that R. terrigena PCM8 potentially produce double activity of ACCD and nitrogenase and therefore it can be a good candidate as plant growth promoting under stress condition.

Many raw vegetables, such as salads, are consumed, and consuming raw vegetables contaminated with human and animal feces can lead to a variety of intestinal parasite diseases. The goal of this cross-sectional study was to investigate the incidence of contamination of green leafy vegetables with human intestinal parasites, as well as identify the most common parasite species and any seasonal variation in parasite abundance in green leafy vegetables found and sold for human consumption in various markets and stores in Jeddah. To the best of our knowledge, no research has been conducted on the prevalence of parasite-contaminated vegetables in Jeddah. From September 2020 to July 2021, 250 leafy vegetables (coriander, watercress, lettuce, parsley, leek, and green onion) were collected from various markets and stores in Jeddah. The vegetables were sorted, labelled, and evaluated in the laboratory after being completely washed with distilled water, examined for sediment, staining, and microscopically examined. Chromatographic immunoassay tests were also used to confirm parasite identification. Intestinal parasites were discovered in 35.2% of the vegetables (88/250). Coriander was the most contaminated (64.2%), while green onion was the least contaminated (21.9%). Blastocystis spp. was the most often discovered parasite (55.7%), followed by Strongyloides spp. larva (22.7%) and Entamoeba coli cysts (6.8%). Summer has the greatest percentage of parasites, followed by autumn, while winter has the fewest. There was no statistically significant relationship between the kind of vegetable, seasonal parasite prevalence in green vegetables, and parasite type.These findings highlight the importance of inspecting vegetables grown or imported from endemic countries for parasite contamination. In Jeddah, several fresh green vegetables were tainted with intestinal parasites. This demonstrates that those who consume raw vegetables regularly may be susceptible to parasitic illnesses. These findings highlight the need of monitoring vegetables grown or imported from parasitic-endemic areas. As a result, it is critical to establish strategies and control measures to limit the likelihood of parasites in food-borne diseases.
