Tea made from the dried fruit, leaves, and flowers of R. Rosa pimpinellifolia is a biennial, or perennial shrub cultivated for its fruit (black rose hips) which has been used to treat specific ailments for decades. Rosa spinosissima L., commonly known as the burnet rose, produces a fruit known as black rose hips or Scottish rose hips. Among these species, Rosa pimpinellifolia L. The genus Rosa of the Rosaceae family counts more than 150 species, mainly spread throughout West Asia, Anatolia, North-West Africa, North America, Northern, and Central Europe. Plants and fruits provide fresh, healthy and nutritional food as well as farm-to-table employment. While seeking solutions for health and nutrition, new sources of food are being investigated. pimpinellifolia.Īs the COVID-19 pandemic has taken its worldwide toll in the past year, food bioactives have been suggested to support the immune system against COVID-19 and to promote overall health.

The drying process thus improved the quality, antioxidant activity, and overall phenolic compounds of R. Catechin, epicatechin, quercetin-3-glucoside, protocatechuic acid, chlorogenic acid, quercetin, rutin, fumaric acid, and gallic acid were the major phenolic compounds identified. The convective drying increased hardness, cohesiveness, gumminess, and chewiness while decreasing springiness and resilience. The rehydration was more efficient at 60☌ compared to 20 and 40☌. Vegas-gálves and Peleg models were the most effective to describe the rehydration kinetics.

The Page Model was the most fitted model to predict the drying kinetics. The optimum operating conditions were 67.21☌ and 1.75 m s −1 providing maximum total phenolic compounds, total anthocyanin, DPPH radical scavenging and Ferric Reducing Antioxidant Power (FRAP) values of 1327 ± 5 mg GAE/100 g, 491 ± 2 mg c3g E/100 g, 110 ± 2 mmol TE/g and 698.00 ± 15 mmol ISE/g, respectively. Response surface methodology was used to detect the optimum drying conditions (i.e.

pimpinellifolia fruit (black rose hips) were investigated. The influence of drying conditions on the drying and rehydration kinetics and mathematical modeling of the R. In this present study, the convective drying process was optimized to enhance the quality, antioxidant activity, and phenolic compounds. Rosa pimpinellifolia, commonly known as the burnet rose, has shown huge functional properties and industrial potential.
