In this study, extracts were prepared from the flesh and seeds of Rosa pimpinellifolia L. using different solvents and different extraction methods. Flesh pulp, seed powder, and the obtained extracts were added to the ice cream at 5%. Changes in some physical and chemical properties of the ice cream at the beginning and in the 2nd, 4th, and 6th months of storage were determined. It was found that the process had a very significant effect on dry matter content, pH value, titratable acidity, volume increase, complete melting time, L*, a*, b*, C, H°, and ΔE values, total phenolic content, and total monomeric anthocyanin content (p < .01). It was revealed that storage time had a very significant effect on dry matter content, pH value, titratable acidity, complete melting time, b* and C values, total phenolic content, and ABTS•+ (p < .01). There was no change in the total content of monomeric anthocyanins during the storage period of ice cream samples. Novelty impact statement Nowadays, the use of natural colorants has become widespread and artificial colorants are considered to cause harm to human health. Color and color stability in foods are important factors that determine consumer preference. The ways of obtaining anthocyanins, which give the red color, from many plants and their stability are currently being investigated. However, the growing conditions of these plants and the storage stability of the obtained natural colorant are commercially important. Anthocyanin-based extracts were obtained from the flesh and seeds of R. pimpinellifolia, acquired from a shrub that is naturally grown in Turkey and can meet its water needs with rainwater, and the possibilities of using anthocyanin-based extracts as natural colorants were investigated for the first time. It was concluded that the fruit and extracts of R. pimpinellifolia were a good commercial source of anthocyanins and could be used as a natural colorant due to their color stability during storage.
