Disclosing the potential of Cupressus leylandii A.B. Jacks & Dallim, Eucalyptus...

Almeida, Heloísa H.S.; Crugeira, Pedro Jorge Louro; Amaral, Joana S.; Rodrigues, Alírio; Barreiro, M.F.

Antimicrobial resistance is a major global health concern, threatening the effective prevention and treatment of infections caused by microorganisms. These factors boosted the study of safe and green alternatives, with hydrosols, the by-products of essential oils extraction, emerging as promising natural antimicrobial agents. In this context, four hydrosols obtained from Cupressus leylandii A.B. Jacks & Dallim,...

Semi-automated sequence curation for reliable reference datasets in ITS2 vascul...

Quaresma, Andreia; Ankenbrand, Markus J.; Garcia, Carlos Ariel Yadró; Rufino, José; Honrado, Mónica; Amaral, Joana S.; Brodschneider, Robert

One of the most critical steps for accurate taxonomic identification in DNA (meta)-barcoding is to have an accurate DNA reference sequence dataset for the marker of choice. Therefore, developing such a dataset has been a long-term ambition, especially in the Viridiplantae kingdom. Typically, reference datasets are constructed with sequences downloaded from general public databases, which can carry taxonomic and...

Coffee Extract as a Natural Antioxidant in Fresh Pork Sausage—A Model Approach

Fetsch, Vanessa Tanara; Kalschne, Daneysa Lahis; Canan, Cristiane; Flores, Éder Lisandro de Moraes; Viegas, Marcelo Caldeira; Peiter, Gabrielle Caroline

Consumers are increasingly looking for healthy foods without the addition of synthetic additives. The aim of this study was to evaluate the efficiency of coffee extracts as a natural antioxidant in fresh pork sausage. Firstly, the conditions for obtaining coffee green extracts were optimized (Central Composite Rotatable Design 23, variables: extraction time, ethanol-water ratio, and sample-solvent ratio) in an ...

Green Extraction Strategy Using Bio-Based Aqueous Biphasic Systems for Polyphen...

Dimitrijević, Aleksandra; Marić, Slađana; Jocić, Ana; Tekić, Danijela; Mušović, Jasmina; Amaral, Joana S.

Polyphenols are natural compounds with enhanced antioxidant properties. They are present in relatively high concentrations in fruit/vegetable by-products. Therefore, there is a need for the development of efficient and cost-effective methods for the separation and purification of these valuable compounds. Traditional extraction with organic solvents needs to be switched to novel methods that are more efficient,...

Adulteration of Brain Health (Cognitive, Mood, and Sleep Enhancement) Food Supp...

Paiva, Rafael; Correia, Manuela; Delerue-Matos, Cristina; Amaral, Joana S.

In recent years, the consumption of dietary supplements has grown worldwide, particularly in developed regions. However, this growing market has also become a prime target for adulteration practices, with some manufacturers illegally adding pharmaceuticals into plant-based food supplements (PFS) to enhance their effects. While extensive research has focused on detecting adulterant drugs in PFS tailored for impr...

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...

Unlocking the Potential of Hydrosols: Transforming Essential Oil Byproducts int...

Almeida, Heloísa H.S.; Fernandes, Isabel P.; Amaral, Joana S.; Rodrigues, Alírio; Barreiro, M.F.

The global demand for sustainable and non-toxic alternatives across various industries is driving the exploration of naturally derived solutions. Hydrosols, also known as hydrolates, represent a promising yet underutilised byproduct of the extraction process of essential oils (EOs). These aqueous solutions contain a complex mixture of EO traces and water-soluble compounds and exhibit significant biological acti...

Exploiting the mitogenomes of apis mellifera subspecies to develop an authentic...

Honrado, Mónica; Henriques, Dora; Santos, Joana; Yadró Garcia, Carlos A.; Martín-Hernández, Raquel; Nanetti, Antonio; González, Amelia Virginia

Honey is highly susceptible to adulteration. Currently, the assessment of its geographical origin remains one of the most difficult tasks, which is typically performed by melyssopalynology. Recently, the attention has shifted towards indirect approaches such as the entomological origin based on geographical distribution patterns of honey bee subspecies. Although queens’ trade has impacted the natural subspecies...

Genomic insights into middle eastern honey bee subspecies: population structure...

Henriques, Dora; Yadró Garcia, Carlos A.; Honrado, Mónica; Amaral, Joana S.; Muz, Mustafa Necati; Muz, Dilek; Haddad, Nizar; Al Shagour, Banan

The genetic patterns of Middle Eastern A. mellifera subspecies have been understudied, hindering a comprehensive understanding of honey bee evolutionary history. Here, we studied the genetic integrity of five Middle Eastern subspecies across a broad geographical range: Turkey (A. m. anatoliaca, N=97; A. m. caucasia, N=75; A. m. syriaca, N=18), Jordan and Lebanon (A. m. syriaca, N=238 and N=29), Iran (A. m. meda...

Honrado, Mónica; Henriques, Dora; Santos, Joana; Yadró Garcia, Carlos A.; Medibees Consortium; Pinto, M. Alice; Amaral, Joana S.

As defined by the Codex Alimentarius, honey is the natural sweet substance produced by honeybees from the nectar of plants.1 This natural product is widely appreciated but is also considered one of the foods most prone to adulteration. The increasing demand for monofloral honey and those with protected designation of origin (PDO) has led to increased fraud by mislabeling botanical and geographical origin.2 Veri...
