Effect of taxifolin on physicochemical and microbiological parameters of dry-cured pork sausage

The effect of taxifolin (TXF) with starter cultures (SC), such as Leuconostoc carnosum, or a mixture of strains Pediococcus pentosaceus and Staphylococcus xylosus, on the TXF stability was evaluated. UPLC analysis demonstrated that after 181 days of storage total TXF content was the highest in samples with TXF and L. carnosum (60%), compared to the 1st day of storage. The sausages with TXF and the mixture of P. pentosaceus and S. xylosus (56%) followed next. The samples treated only with TXF retained 40% of TXF, compared to the 1st day of storage. TXF had no significant effect on the growth of lactic acid bacteria. The accumulation of biogenic amines (BA), including histamine and putrescine, was more effectively reduced in sausages inoculated with the TXF plus P. pentosaceus and S. xylosus mixture. Using this mixture, the rate of lipolysis and processes of lipid oxidation were effectively slowed down. Fatty acid (FA) composition was stable in all cases

Investigation of in vitro and in vivo digestibility of black soldier fly (Hermetia illucens L.) larvae protein

In this work, the in vitro and in vivo digestibility of the dried and low-fat black soldier fly (BSF, Hermetia illucens L.) larvae was carried out. The in vitro experiments demonstrated that the digestibility of the dried larvae protein was only 48%. Meanwhile, the protein digestibility of the defatted larvae biomass reached 75%. Based on these findings, the experimental feeds were composed: (a) control feed containing casein, (b) test feed containing defatted larvae biomass and (c) protein-free feed. For protein digestibility studies, experimental feeds were tested in vitro and in vivo. It was found that digestibility of larvae protein in vivo and in vitro reached 85% and 41% respectively. The DIAAS value (73%) for BSF larvae protein digestibility in vivo was determined for the first time. The obtained results suggest that larvae possess an easy digestible AA, therefore, they can be used as highly bio-available protein source for human nutrition
