Polyphenol oxidase and enzymatic browning in apricot (Prunus armeniaca L.): Effect on phenolic composition and deduction of main substrates

open access: yesCurrent Research in Food Science, 2022
In this study, we investigate the effect of enzymatic browning on the phenolic composition of apricot in vivo and in vitro. The in vitro browning was caused by the recombinant latent apricot polyphenol oxidase (L-PaPPO).

Calcium chloride connects potato greening and enzymatic browning through salicylic acid

open access: yesFood Chemistry: Molecular Sciences
Greening and enzymatic browning are important factors causing post-harvest losses in potatoes. Although they are two different biological processes, there are some common inhibitors between them.

“Cold caramelization” of glucosamine under UV-C radiation

open access: yesFood Chemistry Advances, 2022
The non-enzymatic browning of glucosamine (GlcN) under UV-C radiation at 25°C, referred to as “cold caramelization”, was examined. Several UV-C exposure times of 0, 20, 60, 120 min at two GlcN concentrations of 15% and 30% were chosen.

Characterizing the salivary RNA landscape to identify potential diagnostic, prognostic, and follow‐up biomarkers for breast cancer

open access: yesMolecular Oncology, EarlyView.
This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

Continuous Evolved Gas Analysis and Thermal Analysis in Micro-scale Roasting of Foods

open access: yesCHIMIA, 2002
In roasting processes of foods, non-enzymatic browning reactions lead to the formation of water and carbon dioxide. Continuous monitoring of the evolution of moisture and carbon dioxide would offer an interesting tool for determining reaction ...
