    Quality and microbial inactivation of powdered Irvingia gabonensis using moringa and different storage materials
    (Faculty of Agriculture, Haran University, Turkey, 2020) Musliu Olushola Sunmonu; Adeshina Fadeyibi; Saheed Olabanjo
    A biological approach can be used to maintain the quality of food products for an extended storage life. In this research, the effects moringa parts (B), botanical concentration (C) and, storage material (S) on the quality and microbial inactivation were investigated for storage of powdered Irvingia gabonensis. The products were mixed with different parts of the powdered B (leaf, seed and bark) to form varying C (10− 20ppm); and then stored in different S (calabash, sisal and jute sacks) for 3 months. The proximate and microbial compositions of the stored products were determined using standard methods. Results show that the proximate, total coliform, viable and fungi counts decreased with C (p< 0.05). Also, the effect was more pronounced in the product stored in the jute sack treated with the 20ppm powdered moringa leaf. This can therefore be used for storing powdered Irvingia gabonensis.

    Quality Retention and Inhibition of Thermophiles in Milk Using a Novel 3-Stage Recyclable Batch Pasteurizer
    (Journal of Food Engineering and Technology, 2022) Musliu Olushola Sunmonu; Adeshina Fadeyibi; Mumeen Habeeb Olalekan
    Milk quality decline and proliferation of microorganism can be prevented by heat-treatment. This however can denature the nutrients under excessive processing condition. There is therefore a need to selectively apply and evaluate this technology for milk pasteurization. In this research, the performance of a novel 3-stage recyclable batch milk pasteurizer operating at varying temperature (63– 71 °C), stirring speed (15 – 25 rpm) and holding time (15 sec – 30 min) was determined. The equipment has a hot water storage, pasteurization, and cooling tanks, which maintain the temperature of the pasteurized milk sample to 3–5oC. The nutritional quality and the thermophile loads, including Streptococcus, Clostridium, Micrococcus, and Lactobacillus in the sample were determined as performance indices. The results show no significant trace of the thermophiles (p < 0.05) and a high value of the nutritional composition at 63°C, 25 rpm stirring speed and 15 min holding time. The quality of the product decreased progressively with an increase (p < 0.05) in the temperature and speed for all holding time. Thus, the equipment can be used for milk pasteurization with a reduced nutrient denaturation and thermophiles proliferation.
