  • response surface methodology based optimization of decontamination conditions for escherichia coli o157 h7 and salmonella typhimurium on fresh cut celery using thermoultrasound and Calcium Propionate
    International Journal of Food Microbiology, 2011
    Co-Authors: Tae Yeon Kwak, Minsuk Rhee

    Abstract:

    Abstract A combination of thermoultrasound (temperature: 50, 55, 60 °C; time: 10, 15, 20 min with the frequency of 40 KHz) and Calcium Propionate (concentration: 1, 2, 3%, w/v) treatment was applied to decontaminate Escherichia coli O157:H7 and Salmonella enterica serovar Typhimurium (S. Typhimurium) from fresh-cut celery. Using a Box–Behnken experimental design, predictive quadratic equations were developed for treatment-based population reductions of E. coli O157:H7 (R2 = 0.98, p   0.05) were observed in the color and shear force resistance of the treated celery. The optimum treatment conditions were 60 °C thermoultrasound with 2% Calcium Propionate for 15 min (E. coli O157:H7) and 59 °C thermoultrasound with 2% Calcium Propionate for 17 min (S. Typhimurium). Scanning electron microscopy was used to confirm membrane disruption in the treated microbial cells in each optimal condition. The combined treatment of thermoultrasound and Calcium Propionate contributes to the effective inactivation (more than 5 log reduction) of E. coli O157:H7 and S. Typhimurium on fresh-cut celery. Furthermore, this treatment extends fresh storability without physical quality deterioration.

  • water availability and Calcium Propionate affect fungal population and aflatoxins production in broiler finisher feed during storage
    Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2014
    Co-Authors: Sahib Alam, Hamid Ullah Shah, Nazir Ahmad Khan, Abdul Sattar Shah, Naresh Magan

    Abstract:

    The aim of this study was to investigate the effects of Calcium Propionate, water activity (aw) and incubation time on the total fungal count and aflatoxins B1 (AFB1), B2 (AFB2), G1 (AFG1) and G2 (AFG2) production in the broiler finisher feed. The feed was added with Calcium Propionate (5 g kg–1), adjusted to 0.85, 0.90 and 0.95 aw and stored for 28 days at 25°C, analysing for mould growth and aflatoxins production every 7 days. Analysis of variance indicated that all the factors (preservative, aw and storage time) alone and in combination significantly (p < 0.001) affected the total fungal count and aflatoxins production in the feed. Minimum total fungal counts (1.99 × 102 CFU g–1) were observed in Calcium Propionate feed at 0.85 aw on day 1 and the highest (4.36 × 109 CFUs g–1) in control sample at 0.95 aw on day 28 of storage. During the storage period, AFB1 content in control samples increased from 11.35 to 73.44, from 11.58 to 81.81 and from 11.54 to 102.68 ng g–1, whereas in preserved feed the conte…

  • Influence of Calcium Propionate, water activity and storage time on mold incidence and aflatoxins production in broiler starter feed
    Animal Feed Science and Technology, 2014
    Co-Authors: Sahib Alam, Hamid Ullah Shah, M. Afzal, Naresh Magan

    Abstract:

    The effect of Calcium Propionate at a dose of 5 g/kg on total fungal count and aflatoxins B1 (AFB1), B2 (AFB2), G1 (AFG1) and G2 (AFG2) production in broiler starter feed stored at 0.85, 0.90 and 0.95aw was investigated at 7 days interval for 28 days.
