Abstract:
The main objective of this work was to evaluate the combined effect of a biotechnology
process, based on selected yeast strains, and a high-pressure homogenization (HPH) treatment
on the microbiological quality, structural organization of proteins, chitin content, and antioxidant
activity of a mixture of cricket powder (Acheta domesticus) and water. Compared to untreated
samples, the cricket matrix treated with HPH four times at 180 MPa promoted the growth of the
inoculated Yarrowia lipolytica and Debaryomyces hansenii strains. HPH did not affect the concentration
of chitin; however, the combination with microorganisms tended to reduce the content. Although the
antioxidant activity increased from 0.52 to 0.68 TAC mM/TE after a 48 h incubation in the control, it
was further improved by the combination of HPH and D. hansenii metabolism, reaching a value of
0.77 TAC mM/TE. The combination of the two approaches also promoted a reduction in the intensity
of bands with molecular weights between 31 and 21.5 kDa in favor of bands with a lower molecular
weight. In addition, HPH treatment reduced the number of accessible thiols, suggesting protein
structure changes that may further impact the technological properties of cricket powder.
