Quality characteristics and protein digestibility of Protaetia brevitarsis larvae
Herein, the in vitro protein digestibility of lyophilized Protaetia brevitarsis larvae flour with and without defatting using 70% ethanol was compared with beef loin. Proximate analysis showed that the defatted larvae contained the high...

description |
Herein, the in vitro protein digestibility of lyophilized
Protaetia brevitarsis larvae flour with and without
defatting using 70% ethanol was compared with beef loin. Proximate analysis
showed that the defatted larvae contained the highest protein content
(p < 0.05). The viable counts of total aerobic
bacteria, Escherichia coli, and coliform bacteria decreased
significantly after defatting the larval samples with 70% ethanol
(p < 0.05). Measurement of α-amino group
content and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE)
revealed higher amounts of low molecular weight proteins in the larvae compared
to beef loin (p < 0.05). After in vitro digestion, the
degree of protein hydrolysis of the digesta was higher for both larvae samples
compared to beef loin (p < 0.05). No change was observed
in the in vitro larval protein digestibility after defatting.
These results highlight the excellent protein digestibility of P.
brevitarsis larvae with high protein content. Defatting insect
flour with 70% ethanol could enhance microbial safety while maintaining
excellent protein digestibility. |
