    Leafy green vegetables are often linked to food-borne illness, and consumers often wash these products at home as a safety measure. The efficiency of household washing to reduce the bacterial content was analyzed with and without E. coli inoculation, and only washing in a high flow rate (8 L/min) without E. coli resulted in statistically significant reductions. This study shows the inefficiency of tap water washing methods available for the consumer, and even after washing, the products contained high levels of bacteria that in a high dose and under certain circumstances may cause illness.

    Optimization of extrusion conditions for the production of instant grain amaranth-based porridge flour

    Olamide A. Akande, Dorothy Nakimbugwe and Ivan M. Mukisa

    Version of Record online: 12 SEP 2017 | DOI: 10.1002/fsn3.513

    Six formulations were developed using the least cost formulation software having grain amaranth as its base. The acceptability of the formulations was evaluated using a 9-point hedonic scale, and the extrusion process of the most acceptable porridge flour was optimized by response surface methodology (RSM). The effect of feed moisture content and barrel temperature was determined after protein and vitamin A retention, iron and zinc extractability, and in vitro protein digestibility analyses were carried. The optimum formulation was then assessed for its nutritional composition, physicochemical properties, and consumer's acceptability.

    Partial characterization of starches from major banana (matooke) cultivars grown in Uganda

    Version of Record online: 31 AUG 2017 | DOI: 10.1002/fsn3.505

    The composition, morphology, pasting properties, swelling power, solubility, water holding capacity, Freeze thaw stability and clarity starch from five cultivars of the East African Highland Banana (AAA-EAHB) was performed in this study. The SEM of starch from five EAHB cultivars showed a mixture of irregular granule shapes with smooth surfaces with the average diameter size ranging between 16.31 and 21.98 µm and the amylose content of these starches was between 11% and 13%. The starches peak viscosity ranged between 488.42 and 558.66 RVU. The EAHB starches exhibited relatively low pasting temperatures (˂75°C), a high peak viscosity (488.42–558.71 RVU), high level of viscosity breakdown (235.00–311.92 RVU) and low set-back values (61.21–104.33 RVU).

    Evaluation of peanut skin and grape seed extracts to inhibit growth of foodborne pathogens

    The objective of this study was to evaluate the antimicrobial effects of peanut skin extract (PSE) containing A-type procyanidins and grape seed extract (GSE) containing B-type procyanidins against select foodborne pathogens (Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella Typhimurium). GSE had a significantly lower MIC (p ≤ .05) than PSE for L. monocytogenes (GSE = 60.6 ppm, PSE > 68.2 ppm), and S. Typhimurium (GSE = 45.7 ppm, PSE = 60.6 ppm), but no difference in inhibition of E. coli O157:H7. Since GSE contributed to greater inhibition, GSE extract was fractionated.

    Influence of particle size and extraction solvent on antioxidant properties of extracts of tea, ginger, and tea–ginger blend

    Version of Record online: 29 AUG 2017 | DOI: 10.1002/fsn3.509

    Thumbnail image of graphical abstract

    The influence of particle size and extraction solvent on the antioxidant properties of aqueous and ethanolic extracts of tea (Camellia sinensis), ginger (Zingiber officinale), and tea–ginger (2:1) blend were investigated. The study suggests that the optimum powder size that would maximize antioxidant extraction is dependent on the solvent used and the antioxidant property being measured.
