Optimum conditions for expression of oil from Allanblackia floribunda seeds and assessing the quality and stability of pressed and solvent extracted oil

The study was carried out to establish the optimum conditions for the extraction of oil from Allanblackia floribunda nuts and also assess the quality and stability of both the crude pressed oil (CPO) and solvent extracted oil (SEO). The optimum conditions of extraction were established by varying the moisture levels of the milled seed samples under different temperatures. The oil was expressed using a manual...

An investigation into the feasibility of production and characterization of starch from “apantu” plantain (giant horn) grown in Ghana

The aim of this research project is to develop a new product (plantain starch) as another way of extending the shelf-life of plantain and to determine the quality of plantain starch based on physicochemical properties, as well as, to determine whether plantain starch has unique characteristics compared to other sources of starch. Plantain starch was extracted from mature unripe plantain (Musa sapientum) of a variety...

Tissue distribution and elimination of erythromycin in giant freshwater prawn (Macrobrachium rosenbergii) depletion

Adult giant freshwater prawns (Macrobrachium rosenbergii) were fed with practical diets medicated with erythromycin (50 and 100 mg/ kg shrimp for 7 days), while erythromycin residues in their muscle were determined by LC-MS/MS method through TUV Rheinland Aimex Vietnam Co., Ltd. Interpolation of the study’s data, following European Agency for the Evaluation of Medicinal Products Guidelines, gave a withdrawal...

Accumulation and clearance of orally administered erythromycin in adult Nile tilapia (Oreochromis niloticus)

Nile tilapia (Oreochromis niloticus) were medicated with erythromycin base via the medicated ration at 50 and 100 mg erythromycin·kg-1 fish body weightday-1 for 7 days. Erythromycin residues in their muscle were determined by LC-MS/MS method through TUV Rheinland Aimex Vietnam Co., Ltd.  The results predicted withdrawal time for Nile tilapia was 33 days (908°C-day) if treated by the former...

Pediococcus spp. – A potential probiotic isolated from Khadi (an Indian fermented food) and identified by 16S rDNA sequence analysis

The probiotic potential of the lactic acid bacteria (LAB) isolated from fermentedKhadi was investigated. The pure culture of the isolate GS4, was subjected to microbiological, biochemical characterization and 16S rDNA gene sequence analysis for species confirmation. Among other probiotic properties, GS4 exhibited antibacterial ability against Staphylococcus aureus (ATCC 25923), Escherichia...

Effect of irradiation on inoculated Salmonella parathyphi B and the colour of freeze-dried egg yolk

The effect of irradiation on the colour intensity of freeze-dried egg yolk samples (FDEY), from poultry birds given feed containing different concentrations of annatto extract was investigated. Concentrations of 1, 4, 7 and 10 % of annatto extracts were used in the poultry feed formulation and these were compared with feed containing no additive as well as one containing a commercial feed colourant, ‘carophyll...

Influence of cold storage and addition of various lactations on properties of buffalo’s and cow’s milk

The effect of cold storage (4 - 5°C) with blending different milkings to cold stored milk on some chemical composition, rheological properties and microbiological quality of buffalo’s and cow’s milk were studied. The results indicated that there are no significant effects on TS, fat and total protein contents of cold stored of buffalo's and cow's milk whereas, the acidity values slightly...
