Performance of Different Seedlings Accessions of Acacia senegal (L.) Willd in Bauchi, Nigeria

Abstract: The seeds of eight accessions of Acacia senegal (L.) Willd gum arabic was collected from farmers fields in Yobe and Borno States of Nigeria. Seedlings raised from the seeds were evaluated for the following morphological characters: seedling height, stem girth, number of leaves, and number of days to transplanting. Results obtained indicated that morphological characters differed significantly (P < 0.05) among the accessions. Some accessions had outstanding seedling features for rapid growth. Hence, there were genotypic differences that could be explore and exploited for genetic improvement and establishment of gum arabic plantations.

Gallate-type catechin-containing drink

Research Article Morphological and Physicochemical Characterization of Ipin Gum (Ficus elastica)

Abstract: Ipin gum (Ficus elastica exudate gum) is exudate gum from a plant growing naturally in the forest of Nigeria. The gum is yet to be commercially exploited as the physicochemical properties of this gum are yet to be characterized. Various physicochemical methods, scanning electron microscopy (SEM), X-ray diffraction spectrometry (XRD) and Fourier transform infrared spectroscopy (FITR) were employed to characterize this gum in the present study. SEM analysis suggested that the native gum has irregular particle size. The XRD pattern of the native gum indicates a completely amorphous structure. Elemental analysis of the gum shows potassium,600.0±1.52mg/g, sodium 300.23±0.2mg/g, manganese 0.31±0.00mg/g, magnesium 410.33±1.0mg/g, Iron 8.7±0.00mg/g and zinc 61.1±0.22mg/g. Physicochemical parameters shows moisture content to be 7.68±0.15%, Ash content 2.70±0.30%, Protein content 2.08±0.02%, pH 5.5±0.10, Viscosity 22.10±0.50, Refractive index 1.34±0.01, Water holding capacity 84.90±4.25%, specific rotation -25.4±0.4 degree, swelling index 9.50±1.10% and Emulsifying capacity 17.29±0.20cm-1. These results compared favourably with acacia senegal gum (gum arabic) and makes ficus elastica exudate gum highly recommendable for use in food and pharmaceutical industries.The major functional groups identified from FTIR spectrum include 3641cm-1 (OH), 1731cm-1 (CH3CO), 1632cm -1 (-COO-), 1429cm-1 (-COO-) and 1249cm-1 (-CH3CO).

Production and characterization of Ziziphus jujuba extract-loaded composite whey protein and pea protein beads based on Na-alginate/IFPG (insoluble fraction of Persian gum).

Abstract: BACKGROUND This research aimed at the fabrication of jujube extract (JE)-loaded beads by extrusion, using whey protein isolate (WPI), chickpea protein concentrate (PPC) and a combination of two types of hydrocolloid insoluble fraction of Persian gum (IFPG) and sodium alginate (Al). RESULTS The JE-loaded beads with the highest encapsulation efficiency (10.87%) and polyphenol content (120.8 mg/l gallic acid) were obtained by Alginate-IFPG/PPC at 4 °C. The Al-IFPG, Al-IFPG/WPI and Al-IFPG/PPC beads revealed 5.66, 6.85 and 5.76 mm of beads size, respectively and almost all of them engrossed a homogeneous and spherical structure. The Fourier-transform infrared spectroscopy data proved the stable structures of the Alginate-IFPG beads are due to hydrogen bonding and electrostatic interactions. The thermostability of beads loaded with JE based on Al-IFPG/WPI were significantly enhanced, compared to pure Al-IFPG. The texture evaluation of JE-loaded beads based on Al-IFPG incorporation with WPI revealed increment the hardness of beads. CONCLUSION Thus, the outcomes of this study confirm the potential of Al-IFPG complex beads for the effective delivery of jujube extract via incorporation into pea and whey proteins and expand its use in products.
