Characterization of Moringa oleifera leaf polysaccharides extracted by coupling ionic liquid separation system with ultrasound irradiation

Otu, P. N. Y.; Osae, R.; Abdullateef, M. T.; Cunshan, Z.; Xiaojie, Y.; Azumah, B. K. (Blackwell Publishing Inc., 2020)

Replacement of organic solvents and short time for purification of polysaccharides has gained attention of researchers. Ionic liquid (IL) was optimally utilized to achieve the mentioned target. IL was coupled with ultrasound ...
Dual‐frequency ultrasound‐assisted alcohol/salt aqueous two‐phase extraction and purification of astragalus polysaccharides.

Chikari, F.; Han, J.; Wang, Y.; Luo, P.; He, X.; Kwaw, E.; Otu, P. N. Y. (Wiley, 2020)

The study investigated the effect of dual-frequency ultrasound-assisted alcohol/salt aqueous two-phase extraction and desalination on the yield, microstructure and antioxidant properties of Astragalus polysaccharides (APS). ...
Heat and/or ultrasound pretreatments motivated enzymolysis of corn gluten meal: Hydrolysis kinetics and protein structure

Zhou, C.; Hu, J.; Yu, X.; Yagoub, A. E. A.; Zhang, Y.; Ma, H.; Otu, P. N. Y. (Science Direct, 2017)

The purpose of this study was to investigate the effect of pretreatments of heat (HP), ultrasound (UP), and combinations of heat/ultrasound (HPUP) and ultrasound/heat (UPHP) on protamex-catalyzed enzymolysis of corn gluten ...
Influence of shea butter, bee wax and cassava starch coatings on enzyme inactivation, antioxidant properties, phenolic compounds and quality retention of tomato (Solanum lycopersicum) fruits

Osae, R.; Apaliya, M. T.; Alolga, R. N.; Kwaw, E.; Otu, P. N. Y.; Akaba, S. (2022)

This study explored the effect of different locally produced edible coating material, bee wax (BW), shea butter (SB) and cassava starch (CS) coatings on the physical and chemical properties of tomato fruits stored at 20 ...
Simultaneous multifrequency: A possible alternative to improve the efficacy of ultrasound treatment on cherry tomato during storage

Mustapha, A. T.; Zhou, C.; Sun, Y.; Wahia, H.; Sarpong, F.; Owusu‐Ansah, P.; Osae, R.; Otu, P. N. Y.; Ma, H. (Wiley, 2019)

Background: As newer technologies in the field of medical imaging continue to expand, development of unique techniques for optimizing image quality and minimizing radiation dose becomes very necessary for improve diagnosis ...
Sonozonation: Enhancing the antimicrobial efficiency of aqueous ozone washing techniques on cherry tomato

Mustapha, A. T.; Zhou, C.; Wahia, H.; Amanor-Atiemoh, R.; Otu, P. N. Y.; Qudus, A.; Ma, H. (Science Direct, 2020)

Ultrasound requires high power and longer treatment times to inactivate microorganisms when compared to ultrasound combined with other technologies. Also, the antimicrobial efficiency of aqueous ozone increases with an ...
Sorghum Bicolor L. leaf sheath polysaccharides: Dual frequency ultrasound-assisted extraction and desalination.

Otu, P. N. Y.; Haonan, J.; Cunshan, Z.; Hongpeng, Y. (Science Direct, 2018)

Supramolecules extraction using single frequency ultrasound technology application has directional effect as a shortcoming. Thus, optimum disruption of materials for better yield is curtailed. One possible solution to this ...
