Abstract The effect of different sugar types on the sensory characteristics of Maillard reaction products (MRPs) obtained from sunflower protein hydrolysates was evaluated. MRPs were prepared at 120 °C for a time of 2 h and a pH of 7.4. Results showed that the browning intensity, colour development and free and total amino acids of MRPs were highly affected by the sugar types. Peptide-xylose-cysteine (PXC) were more dark-brown in colour with lower free and total amino acid (FAA and TAA) content compared to the other MRPs. However, PXC showed great mouthfulness and continuity taste with stronger meat-like flavour and umami taste compared to MRPs. MRPs from hexose except PGaC, showed acceptable mouthfulness and continuity taste while PLC and PMC and PGaC showed higher caramel-like flavour and bitter taste. Furthermore, pentose sugars (xylose) were the great precursor of sulphur-containing compounds. It could be concluded that sunflower peptides, xylose, cysteine model system could be a good precursor of flavour enhancers.

The aim of the present study was to improve the sanitary quality of in vitro-produced bovine embryos by using plant protein hydrolysates (plant peptones) as substitutes for animal proteins. Peptones were compared with bovine serum albumin (BSA) as the protein source in synthetic oviduct fluid medium and the quality of the resulting embryos was determined. Two batches of peptones (wheat and cotton) were selected on the basis of their anti-oxidant properties. When added to the culture medium, both peptones (at 0.56 mg mL–1 for cotton peptone and at 0.18 mg mL–1 for wheat peptone) led to similar developmental and hatching rates compared with 4 mg mL–1 BSA and embryos were equally resistant to freezing and able to elongate after transfer. Surprisingly, a significant decrease in reduced glutathione (GSH) content was observed when embryos were produced with plant peptone instead of BSA. Supplementation of the culture medium with precursors of GSH (cysteine and β-mercaptoethanol) significantly increased the GSH content. A shift of the sex ratio towards male embryos was seen for Day 8 embryos cultured with wheat peptone, whereas no shift was observed for embryos cultured in the presence of BSA or polyvinylpyrrolidone. In conclusion, culture with plant peptones enables embryos to be obtained at a similar rate and of similar quality to that seen following the use of BSA. The use of the plant peptones increased the sanitary quality of the embryos and decreased the cost of embryo production.
