Edible coatings enhance storability and preserve quality of kiwiberry (Actinidi...
Guerreiro, Adriana; Gago, Custódia; Passos, Dário; Martins, Jaime; Cruz, Sandra P.; Guerra, Rui; Veloso, Fernão; Antunes, Maria DulceKiwiberries, an emerging fruit variety with increasing consumer demand, face significant commercialization challenges due to their short shelf life. This study evaluates the effectiveness of edible alginate-based coatings in extending the shelf life of kiwiberries. Two emulsion types—coarse (Coarse) and nanoemulsions (Nano)—and two application methods—spraying (Spray) and dipping (Dip)—were tested. Additionally...

Souza, Mariana; Martins, Nuno; Fonseca, Daniela; Cabrita, Maria João; Gago, Custódia; Guerreiro, Adriana; Miguel, Maria da Graça; Antunes, Maria DulceAvocado ( Persea Americana Mill.) has gained popularity as a widely produced and consumed fruit worldwide, raising concerns about its storage and transportation. The avocado, being a climacteric fruit sensitive to chilling injury, faces challenges that affect its shelf life and commercial viability. This research delves into the effectiveness of edible sodium alginate 2 % (weight/weight, w/w) (SA) and carnauba ...

Sucederam-se outras, ...
1-Metilciclopropene and lemongrass essential oil nanocoatings effects on the pr...
Gago, Custódia; Guerreiro, Adriana; Cruz, Sandra; Martins, Nuno; Cabrita, Maria João; Miguel, Maria; Faleiro, Maria; Antunes, MariaThe effects of coating ‘Rocha’ pear with alginate-based nanoemulsions enriched with lemongrass essential oil (LG) was evaluated and compared to the usual 1-MCP treatment. Fruit were treated with 1-MCP (312 nL L−1) or coated with nanoemulsions: sodium alginate 2 % (w/w) + lemongrass essential oil 1.25 % (w/w) (LG 1.25 %) or lemongrass essential oil 2.5 % (w/w) (LG 2.5 %). Then, fruit were stored at 0 °C and 90–9...
Biodegradable active packaging enriched with essential oils for enhancing the s...
Rusková, Magdaléna; Opálková Šišková, Alena; Mosnáčková, Katarína; Gago, Custódia; Guerreiro, Adriana; Bučková, Mária; Puškárová, AndreaThe strawberry (Fragaria ananassa) is a nutrient-rich fruit with high content of healthbeneficial compounds. However, strawberries are susceptible to mechanical damage and microbiological contamination which can cause changes in fruit sensory properties. These changes consequently effect on ripening and shelf life of the strawberry. In recent years, essential oils (EOs) have been famous for their antimicrobial ...
Antimicrobial activity of different nanocellulose films embedded with thyme, ci...
Casalini, Sara; Baschetti, Marco G.; Cappelletti, Martina; Guerreiro, Adriana; Gago, Custódia; Nici, Silvia; Antunes, Maria DulceThe study focuses on the antimicrobial activity of nanocellulose films (NFC) embedded with thyme, cinnamon, and oregano essential oils for active packaging application. The activity against model pathogenic bacteria was first tested to obtain each oil's minimum inhibitory concentration (MIC). The tests showed that the surface area of the films and the quantity of essential oil strongly influenced the antimicrob...

Antunes, Maria Dulce; Guimarães, Ana Clara; Gago, Custódia; Guerreiro, Adriana; Panagopoulos, Jorge; Vilas Boas, Eduardo; Miguel, Maria da GraçaThe present research intents to study skin fatty acids and physiological disorders developed during cold storage in ‘Golden Delicious’ apples treated with 1-MCP and calcium. Harvested fruits were treated with calcium chloride (Ca), 1-MCP (MCP), Ca + MCP or no treatment (control) and then subjected to cold storage at 0.5 °C for 6 months. Fatty acids’ composition, malondialdehyde (MDA) and the physiological disor...
