Cilj ovog istraživanja bio je utvrditi fizikalno-kemijska svojstva, sadržaj bioaktivnih spojeva i nutritivni potencijal dvaju proizvoda planike: džema i vodene infuzije listova. Način pripreme džema varira postupkom pasiranja: nepasirani (NP1) i pasirani džem (P2). Džem tretmana NP1 imao je značajno viši sadržaj ukupne i topljive suhe tvari te višu pH- vrijednost u usporedbi s P2. Također, tretman pasiranja utjecao je i na promjenu boje gotovog proizvoda prilikom čega je za džem P2 utvrđeno svjetlije crveno, a džem NP1 tamnije crveno obojenje. Postupak pasiranja pridonio je povećanju sadržaja pojedinih bioaktivnih spojeva u P 2, p rilikom č ega j e u d žemu t retmana P 2 utvrđen 17% viši sadržaj vitamina C, značajno viši sadržaj polifenolnih spojeva kao i viši antioksidacijski kapacitet u usporedbi s NP1. No, oko 3 puta viši sadržaj β-karotena utvrđen je u NP1 džemu. Također, iz analize vodene infuzije listova vidljiv je visok sadržaj bioaktivnih spojeva, a posebice ukupnih fenola (715,79 mg GAE/100 g svježe tvari). Temeljem svega, može se zaključiti kako oba proizvoda obične planike pokazuju visok nutritivni potencijal i značajnu funkcionalnu vrijednost, a time predstavljaju zdravstveno vrijedne proizvode široke mogućnosti upotrebe.

Arbutus unedo spirit is a valuable product in Mediterranean countries. This spirit is usually marketed in Portugal without wood ageing. This work aims to characterize the ageing effect on the Arbutus unedo spirit, for three and six months with oak wood (Quercus robur L.) submitted to different toasting levels, based on its chemical composition and its sensory properties. For this purpose, several parameters were analysed: acidity, pH, dry extract, and volatile compounds (methanol, acetaldehyde, ethyl acetate and fusel alcohols). The volatile compounds were identified by GC-MS and quantified by GC-FID. Sensory analysis was performed by a trained panel, who have profiled this beverage, as well as the changes acquired during ageing. Spectroscopic techniques, namely FTIR–ATR, were applied to discriminate the different beverages produced. The results highlighted an increase in Arbutus unedo spirit’s quality with the wood contact, mainly based on the sensory attributes. Additionally, they showed that the best beverages were produced using oak wood with medium toasting levels during three months of ageing.

Arbutus unedo L. (Ericaceae) is an evergreen shrub widely distributed in the Mediterranean region, particularly through the Moroccan forests. It is an important medicinal plant of great scientific interest due to its nutritional, pharmacological, and chemical properties. The objective of this review is to provide insights into traditional medicinal uses and phytochemical and pharmacological properties of A. unedo from Morocco. In Morocco, the plant has been used as a traditional medicine to treat several pathological conditions. Many phytochemical compounds have been reported in the plant, of which vitamins, carotenoids, flavonoids, polyphenols, tannins, and their derivatives are the most prevalent. Leaves and fruits of A. unedo contain the most significant number of phytochemicals among the species. Furthermore, researchers have demonstrated that A. unedo exhibited antioxidant, anticancer, antibacterial, antidiabetic, antiaggregant, and antihypertensive activities due to the presence of many biochemical compounds with health-promoting properties. According to different toxicity tests, the use of A. unedo is devoid of any significant side effects and/or toxicity. Despite its nutraceutical and health-promoting properties, Moroccan A. unedo remains underexploited mainly, and most of its traditional uses have not yet undergone scientific evidence-based research; therefore, improved knowledge about the potential value of the plant would allow understanding of its biological activity based on its phytochemical compounds that may contribute to the species preservation and valorization.
