Development of bioresidue apple flour with potential application in the food in...
Aichouche, Chaimaa; Pereira, Eliana; Carocho, Márcio; Dias, Maria Inês; Calhelha, Ricardo C.; Heleno, Sandrina A.; Fernandes, Filipa AlexandraFood loss and residues have attracted the attention of many sectors around the world due to negative environmental and economic effects. Several studies identify this bioresidue with potential to be explored and used as natural ingredients, benefiting environment and economy, and producing functionalized products. This study aimed at the nutritional, chemical and bioactive evaluation of flours obtained from app...
Chemical profiles and bioactivities of polyphenolic extracts of Lavandula stoec...
Silva, Beatriz Nunes; Cadavez, Vasco; Caleja, Cristina; Pereira, Eliana; Calhelha, Ricardo C.; Molina, Adriana K.; Finimundy, Tiane; Kostic, MarinaThis study assessed the chemical profiles and bioactivities of the infusions, decoctions and hydroethanolic extracts of tarragon, basil and French lavender. The extracts were chemically characterised (HPLC-DAD-ESI/MS) and their bioactivities were evaluated in vitro. All extracts revealed antimicrobial, antifungal and antioxidant properties. French lavender extracts showed higher total phenolic content, regardle...
Chemical and Bioactive Evaluation of Essential Oils from Edible and Aromatic Me...
Sprea, Rafael M.; Caleja, Cristina; Finimundy, Tiane C.; Calhelha, Ricardo C.; Pires, Tânia C.S.P.; Amaral, Joana S.; Prieto Lage, Miguel A.The Lamiaceae family, which includes several well-known aromatic plants, is scientifically relevant due to its essential oils (EOs). In this work, four EOs from Mediterranean species, namely Origanum vulgare L., Rosmarinus officinalis L., Salvia officinalis L., and Thymus vulgaris L., were evaluated for their volatile profiles and the biological activity in vitro to assess their potential use in the food and co...

Nutritional profiling, fiber content and in vitro bioactivities of wheat-based ...
Mesias, Marta; Morales, Francisco J.; Caleja, Cristina; Pires, Tânia C.S.P.; Calhelha, Ricardo C.; Barros, Lillian; Pereira, ElianaThis study evaluated the nutritional profile and fiber content of innovative formulations of wheat-based biscuits enriched with chia seeds, carob flour and coconut sugar. The in vitro antioxidant, cytotoxic, anti-inflammatory and antimicrobial activities were also investigated to understand the potential health advantages of the incorporation of these new ingredients. The novel biscuits demonstrated significant...
Grain Products: Traditional and Innovative Technologies
Gómez, Manuel; Pereira, ElianaThe current knowledge regarding various cereals, their composition, and their processing methods is extensive. There is a solid understanding of the three most well-known cereals (wheat, maize, and rice), as well as for widely consumed products like bread, pasta, or beer. However, when dealing with other cereals or grains, or with less popular products, the knowledge base is not as robust, necessitating further...
Phytochemical composition and bioactive potential of Melissa officinalis L., Sa...
Silva, Beatriz Nunes; Cadavez, Vasco; Caleja, Cristina; Pereira, Eliana; Calhelha, Ricardo C.; Añibarro-Ortega, Mikel; Finimundy, Tiane; Kostic, MarinaPlants are rich in bioactive phytochemicals that often display medicinal properties. These can play an important role in the production of health-promoting food additives and the replacement of artificial ones. In this sense, this study aimed to characterise the polyphenolic profile and bioactive properties of the decoctions, infusions and hydroethanolic extracts of three plants: lemon balm (Melissa officinalis...
Use of bio-waste of Ilex paraguariensis A. St. Hil. (Yerba mate) to obtain an e...
Menezes, Barbara de Sena Nunes; Caleja, Cristina; Calhelha, Ricardo C.; Pinela, José; Dias, Maria Inês; Stojković, Dejan; Soković, MarinaIn this work, a comparison between the extracts of dehydrated yerba mate (Ilex paraguariensis) and bio-waste of yerba mate leaves from the Brazilian industry was made. The incorporation of the functional extract as a preservative/functional ingredient in a pastry product (pancakes) was tested. The individual profile of phenolic compounds was determined by HPLC-DAD-ESI/MS, and the bioactive potential was assesse...
Evaluation of antimicrobial and antioxidant activities of alginate edible coati...
Lopes, Ana I.; Melo, Adma N.F.; Caleja, Cristina; Pereira, Eliana; Finimundy, Tiane C.; Afonso, Tiago B.; Silva, Sara; Ivanov, Marija; Soković, MarinaPlant extracts (PEs) are natural substances that perform interesting bioactivities. However, they have some limitations. In this work, PEs from licorice, eucalyptus, sage, and thyme were produced and characterized. These extracts showed good bioactive properties. Alginate-based edible coatings and films incorporated with the extracts were produced and their antimicrobial and antioxidant properties were determin...
Reuse of fruits and vegetables biowaste for sustainable development of natural ...
Oliveira, Tatiane C.G.; Caleja, Cristina; Oliveira, Beatriz; Pereira, Eliana; Barros, LillianConsidering the annual waste in the food sector that occurs throughout the value chain, it is important to establish strategic measures to reduce, value and reintroduce them into the industrial sector. Additionally, the constant search for the development of sustainable strategies to promote safe and healthy products for consumers has gained great prominence. Biowastes from fruits and vegetables present in thei...
