Abstract: Background: Fruits are relatively easy to authenticate morphologically when intact and fresh. However, the act of processing them into juice gives rise to the possibility of substitution with cheaper products. For this reason, processed food products authentication is primarily significant for consumers, industries, and regulatory agencies. Effective, reliable, and rapid food authentication methods are valuable tools for identification of natural fruit pulp in reconstituted fruit juices to ensure juice quality and safety hence mitigate adulteration and fraud. Molecular-based methods have recently acquired immense priority for their ability to pick food material source at any stage along the food supply chain. This study focused on evaluation of two DNA isolation protocols from processed plant products specifically reconstituted juices. The robustness and sensitivity of the protocol for genomic DNA recovery from processed juices determines DNA quality and purity. This is because the degradation and chemical additives........

Abstract: Ginkgo biloba L. (Gymnosperm) is a medicinal and nutrient-rich plant due to its high level of flavonoid content.Various bioinformatics resources were used in this study for characterization of the phenylalanine ammonia-lyase (PAL) from Ginkgo biloba L. as key enzymes in involved pathway of plant flavonoids, the anthocyanin and other important secondary metabolites in plants.The full-length cDNA of PAL gene sequence (GbPAL) was isolated from G. bilobacontained a 2172bp open reading frame(ORF) encoding a 724 amino acid protein.As well as, multiple alignment analysis and phylogenetic analysis revealed that GbPAL has high identity with other plant PALs.In addition, each subunit is composed of an MIO domain, a core domain and an inserted shielding domain. The highly conserved Ala-Ser-Gly triad, which acts as an active site for cyclization and dehydration for MIO group formation, was......

Abstract: Background: AIDS is highly infectious and leads to mortality and morbidity rates that are high because of opportunitistic infection due to immune-suppression. Materials and Methods: A study population of 130 participants from Machakos County was selected after signed informed consent and followed in a cohort study for a three year period. The participants received health talks on beneficial adherence to ARVs, food intake that allowed biodiversity of 13 plus food species, bioavailability of micronutrients, essential vitamins and use of fortified foods alongside balanced diets and household food supply. Emphasis was made on: receiving 13 plus biodiversity of foods intake, sufficient supply of essential vitamins A, C, D, E, K and others like B Complex especially Biotin and folic Acid, prayers and professional Counseling on adherence to ARVs......

Abstract: Background: Food evaluation and processing play a key role in food preservation. In this context, this work has two main objectives. The first consists of extracting the syrup from two varieties of Moroccan dates, trying to optimize the parameters that influence the extraction. While the second, focuses on the study of the sensory analyses and physico-chemical parameters that influence the preservation of the extracted syrup: pH, titratable acidity and water content. Materials and Methods: The study was carried out on two Moroccan varieties, namely Bouffegouss and Fertat. The syrups were extracted by diffusion by setting the following parameters: temperature, time and the water: pulp ratio. The evaluation of the......

Abstract: This work undertook a comparative chemosystematics study of identified Hibiscus species collected from different parts of Northern Nigeria. Whole plants of H.sabdariffa (SAB), H.rosa-sinensis (ROS), H.syriacus (SYR) and H.rosa-sinensis variegated (ROSV) were collected. Ten (10) qualitative phytochemicals were evaluated in ethanolic extracts of the flower, leaf, bark and root of each Hibiscus species while quantification of phytochemical was carried out on SAB alone. Minitab 16.0 was employed in data analysis.ROSvariegated contained 60% of the phytochemicals investigated in flower while SABand ROSflower contained 50% but it was 40% in ROSV. The leaf of ROSVcontained 100% of all phytochemicals with double presence of tannin and alkaloid. ROSleaf contained 90% of the phytochemicals investigated (lacking only glycoside) while SABleaf contained 80% but leaf was highly concentrated in tannin and flavonoid. ROSVand ROSvariegated contained 70% of the phytochemicals screened......
