  • Does ultrasound improve the extraction of components from soybeans?
  • The conventional extraction of various components from soybeans is suboptimal. The effect of ultrasound on separation and extraction has been studied.Ultrasound intensifies the extraction of valuable components from soybeans, leading to improved yields of protein, oil and solids of ca. 10% after 1 min treatment.
  • Does ultrasound treatment improve protein extraction from pre-soaked soybeans?
  • One study by Fahmi et al. investigated the effects of ultrasound treatment (35 kHz, up to 60 min) on soy slurry protein extraction from pre-soaked soybeans. Theprotein extraction was intensified: the protein content of soymilk increased by 6.3% .
  • Does ultrasound improve protein extraction yield during soymilk production?
  • Ultrasoundimproves protein extraction yield during soymilk production. Ultrasound did not cause cell disruption. Solubility and separation efficiency are both accountable for improved yields. Particle size regime of 2–35 μm experienced greatest impact of ultrasound. Phytic acid stores were localised in protein bodies of dry soybeans using SEM.
  • How is soybean milk produced?
  • Soymilk production includes theaqueous extraction from soybeans, followed by removal of insoluble materials. The conventional extraction of various components from soybeans is suboptimal. The effect of ultrasound on separation and extraction has been studied.
  • Is protein availability a determinant of Okara separation efficiency in soy Slurry Treatment?
  • During treatments of soy slurry using ultrasound, it was possible to identify whether the availability of protein was attributed to the increase in protein extraction yield and/or in the separation efficiency (deliquoring of okara).
  • How do phytic acid stores in soybeans differ from aqueous extraction?
  • Phytic acid stores were localised in protein bodies of dry soybeans using SEM. During soymilk production, aqueous extraction conditions are utilised resulting in suboptimal protein extraction yields. This research focuses on the intensification of extraction yields from soybeans using ultrasound and understanding the reasoning behind the results.
