Background: Passiflora setacea DC. is a passion fruit species native from Brazilian savannah characterized by naturally sweet sensory characteristics. The sensory quality of the pulp can be affected by the growing environment. The effect of training systems (trellis or espalier), seasons (the weather conditions in periods of drought and rain) and addition of seeds to the juice (25%) were evaluated, with emphasis on the sensory quality of P. setacea nectars.
Results: Training systems of P. setacea plantation did not influence flavor or aroma of nectars. Season had an effect on texture attributes. Although training system and season had impact on pH, total soluble solid (TSS) content, titratable acidity (TA), polyphenolics and condensed tannins content, these environment factors had no influence on acceptance. Seeds addition had a negative effect on overall liking. Frequency of consumption of passion fruit and functional food did not influence nectar preference whereas being neophilic or having higher level of knowledge about functional foods favored greater acceptance of P. setacea nectars.
Conclusion: Passiflora setacea nectar is a potential functional beverage, due its bioactive contents. Training system and season had no influence on acceptance as isolated factors. However, there was an interaction between these factors, which could be considered to market projection, as well as the addition of seeds. © 2018 Society of Chemical Industry.

Morphoanatomical analysis of seeds contributes to knowledge of the development of seedlings and identification of species, as well as supporting conservation studies. The conservation of the species belonging to the Passiflora genus is crucial due to of the threats to the genetic resources of these species. Thus, the objective of this study was to morphoanatomically characterize Passiflora seeds, verify possible injuries to the tissues after cryopreservation and thus contribute to the conservation strategies of the species of this genus.

Cryopreservation is an interesting strategy for the long-term conservation of the seeds of the majority of cultivated plants as well as many of the corresponding wild parents. The objective of this study was to evaluate the response of the seeds of different passion fruit species to cryopreservation, as well as to apply multivariate tools to better understand the germinative behavior after thawing, to support the application and repeatability of these methods with other species. Seeds of , , , , , , and were submitted to cryopreservation, and after thawing the following variables were analyzed: emergence percentage (%); mean emergence time (days); mean emergence speed (plantlets.

(PS) is a species of wild Brazilian passion fruit, rich in bioactive compounds. Scientific evidence suggests that food rich in polyphenols can modulate inflammation, thereby playing an important role in preventing chronic non-communicable diseases, such as type 2 diabetes (DT2) and cardiovascular diseases (CVD). This study aimed to investigate the effect of PS consumption on metabolic and inflammatory biomarkers in overweight male volunteers and to identify the underlying mechanism of action using an study using phenolic metabolites isolated from the plasma of volunteers at physiologically relevant concentrations.

Passiflora setacea DC. growing is of interest to the herbal industries since in its leaves are produced secondary metabolites that confer antioxidant, anxiolytic, and antidepressant properties in Passiflora. Therefore, it is important to search for sustainable alternatives that aim to enhance the production of these compounds to add value to the phytomass, such as the inoculation with arbuscular mycorrhizal fungi (AMF) and the application of coconut coir dust, which has not been reported to P.
