Preparation of juice concentrates by nonthermal processing technologies: a multiple hurdle approach
… and high pressure homogenization at 300 MPa (HPH) to extend the refrigerated shelf-life of the juice. Concord grape juice concentrate was inoculated with Salmonella, E. coli O157:H7, L. monocytogenes, and Z. bailii. Salmonella was most resistant to HPP, achieving a >5 log-reduction only after …

Agronomic performance of soybean [Glycine max (L.) Merr.] hybrids
… The few positive high-parent heterosis (HPH) and mid-parent heterosis (MPH) values obtained, suggest that many cross combinations need to be evaluated before heterotic combinations can be identified that will determine the feasibility of commercial hybrid soybean production.</p>

Graphene and Related Materials Inks and Composites for Space Applications
… Utilizing high-pressure homogenization (HPH), I establish a framework for several techniques that enhance the effective use of GRMs, expanding the utility of HPH beyond mere exfoliation to encompass multimaterial and multiphase processing of GRMs and other nanomaterials. The ensuing …

Improving product release from saccharomyces cerevisiae and kluyveromyces lactis by pretreatment for cell wall weakening and selective product release
… through the high pressure homogenisation (HPH). Pretreatments were selected for their ability to weaken the yeast cell wall, rather than to permeabilise the cell. This allowed product release to be concentrated into the disruption step only, not distributed between the disruption and …
