    Correlation of the sensory attributes of thick yam paste (amala) and the functional and pasting properties of the flour as affected by storage periods and packaging materials
    (Wiley, 2020-06-16) Awoyale Wasiu, Oyedele Hakeem Adebowale, Maziya-Dixon Busie,
    This study aims to evaluate the relationship between the sensory attributes of amala and the functional and pasting properties of the yam flour (YF) as affected by stor age periods and packaging materials. Results showed that all the functional (except swelling power) and pasting properties of the YF were significantly affected (p < .05) by the storage periods. The peak and trough viscosities of polypropylene woven sack (PPS) packaged YF have significant negative correlation with the texture (r = −.89 & r = −.90; p < .05), stretchability (r = −.87 & r = −.83; p < .05), moldability (r = −.90 & r = −.89; p < .05), and overall acceptability (r = −.90 & r = −.89; p < .05) of the amala, respectively. Amala produced from polyvinyl chloride container (PVC) packaged YF was generally acceptable even at the 16 weeks of storage. Therefore, packaging YF in PVC may keep most of the properties preferred by the consumers when stored for up to 4 months.

    The functional and pasting properties of unripe plantain flour, and the sensory attributes of the cooked paste (amala) as affected by packaging materials and storage periods
    (Taylor and Francis, 2020-10-07) Awoyale Wasiu, Oyedele Hakeem Adebowale, Maziya-Dixon Busie,
    Unripe plantain flour (UPF) is hygroscopic and gets spoilt if not correctly processed, packaged and stored. Thus, the need to study the functional and pasting properties of the UPF, and the sensory attributes of the cooked paste (amala) as affected by packaging materials and storage periods. The UPF was produced using the standard method, packaged in a polypropylene woven sack (PPS) and polyvinyl chloride container (PVC), stored for 20-weeks at room temperature and analyzed at 4-weeks intervals. Results showed that the solubility index of UPF packaged in PPS had a significant (p < 0.05) positive correlation with the breakdown viscosity (r = 0.90), and a negative correlation with moldability (r = −0.89), mouthfeel (r = −0.92) and the overall acceptability (r = —0.83) of the amala. The peak viscosity of the UPF packaged in PPS had a significant (p < 0.05) negative correlation with the stretchability (r = —0.93), mouldability (r = −0.88), mouthfeel (r = —0.83) and overall acceptability (r = −0.01) of the amala. The packaging materials and storage periods had significant effect (p < 0.05) on the mouldability of the amala. The overall acceptability was higher in the amala prepared from PPS packaged UPF compared to that of the PVC. Therefore, UPF should be stored in PPS to retain its sensory attributes.
