Volatilomic fingerprint of tomatoes by HS-SPME/GC-MS as a suitable analytical p...
Jasmins, Gonçalo; Azevedo, Tânia; Câmara, José S.; Perestrelo, Rosa; Jasmins, Gonçalo; Azevedo, Tânia; Câmara, José; Perestrelo, Rosa<jats:p>Tomatoes are globally esteemed not only for their nutritional value but also for their complex and appealing aroma, a key determinant of consumer preference. The present study aimed to comprehensively characterise the volatilomic fingerprints of three tomato species—Solanum lycopersicum L., S. lycopersicum var. cerasiforme, and S. betaceum—encompassing six distinct varieties, through the application of ...

Perestrelo, Rosa; Lopes, Maria da Graça; Silva, Alda Pereira da; Costa, Maria do Céu; Câmara, José S.; Perestrelo, Rosa; Câmara, José<jats:p>The garden Nasturtium (Tropaeolum majus L.) is increasingly consumed worldwide due to its culinary appeal and perceived health benefits. However, the chemical markers underlying its functional properties remain insufficiently characterized. Building on evidence from a recent human pilot study confirming both high acceptability and dietary safety, we conducted a comprehensive volatilomic and phytochemica...

Unlocking the fatty acid and antioxidant profile of grape pomace: a systematic ...
Abreu, Teresa; Ferreira, Rui; Castilho, Paula C.; Câmara, José S.; Teixeira, Juan; Perestrelo, Rosa; De Abreu Abreu, Maria Teresa; Ferreira, Rui<jats:p>Grape pomace (GP), the main by-product of the wine industry, represents a valuable source of bioactive metabolites with significant potential for valorization in the context of sustainable bioresource management. This study systematically characterizes the fatty acid methyl ester (FAME) profile, total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activities (DPPH, ABTS, ORAC) of...
Edible flowers in modern gastronomy: a study of their volatilomic fingerprint a...
Fernández-Pintor, Begoña; Perestrelo, Rosa; Morante-Zarcero, Sonia; Sierra, Isabel; Câmara, José S.; Perestrelo, Rosa; Câmara, José<jats:p>Given the transformation that gastronomy has undergone in recent years, there is a need to characterize some new foods that are being incorporated into the modern diet. Among them, edible flowers stand out, which are used today not only to enhance the organoleptic properties of gourmet dishes but also for some of the beneficial properties they provide to human health. In this study, the volatilomic fing...
A comparative study of the biological properties of Eugenia uniflora L. fruits ...
Gonçalves, Jéssica; Hontman, Nance; Perestrelo, Rosa; Câmara, José S.; Hontman, Nance; Perestrelo, Rosa; Câmara, José<jats:p>Cardiovascular diseases (CVDs) remain the leading cause of death globally, emphasizing the need for effective preventive strategies. Plant-based foods, rich in phytochemicals, offer a promising potential in CVD prevention. This study investigated the antioxidant, anti-inflammatory, and antihypertensive properties of two Eugenia uniflora L. varieties (orange and purple pitanga) and their leaves. Their an...
Improved methodology to survey veterinary antibiotics in environmental samples ...
Antos, Joanna; García-Cansino, Laura; Ángeles García, María; Ginter-Kramarczyk, Dobrochna; Marina, María Luisa; Zembrzuska, Joanna; Câmara, José S.A μSPEed microextraction combined with ultra-performance liquid chromatography (UHPLC) with UV detection was developed for analysing six veterinary antibiotics (tetracycline, chlortetracycline, oxytetracycline, doxycycline, sulfamethoxazole, and trimethoprim) in environmental samples. To optimise extraction, 12 sorbent cartridges, sample loading cycles, volumes, and pH were assayed. The PS/DVB-RP cartridge, thr...
Microextraction techniques for antibiotics surveillance in the food chain and e...
Antos, Joanna; García-Cansino, Laura; Ángeles García, María; Ginter-Kramarczyk, Dobrochna; Marina, María Luisa; Zembrzuska, Joanna; Câmara, José SousaAntibiotics are commonly used to prevent and treat infections in human medicine, animal farming, and aqua culture. However, their excessive use can result in the development of antibiotic resistance and the presence of antibiotic residues in the food and environment. Therefore, it is essential to monitor antibiotic use and assess resistance, but the lack of standardisation and long-term quantitative data on ant...
Bioconversion of organic waste by insects: a comprehensive review
Shahida Anusha Siddiqui; Harahap, Iskandar Azmy; Osei-Owusu, Jonathan; Saikia, Trideep; Wu, Yuan Seng; Fernando, Ito; Perestrelo, Rosa; Câmara, José S.feed. However, the increase in global agricultural production also means an increase in waste generation, which is mostly improperly managed, especially in low- and middle-income countries where adequate waste man agement infrastructure is limited and inefficient. Consequently, organic waste has become a global burden due to its negative impact on the environment and human health. In this sense, insect-based bi...
