Stirred-type fruit-flavored yogurt was made by adding cornelian cherry paste and sugar at different ratios. The effects of the paste and sugar addition on the physicochemical and organoleptic properties of yogurt were examined. The titratable acidity, pH, viscosity, whey separation, and organoleptic properties of experimental yogurts were determined at weekly intervals for 21 days. Statistically significant differences were found between the control and fruit-flavored yogurts in terms of viscosity and whey separation. The addition of the fruit paste and sugar to yogurt resulted in an increase in the whey separation, and a decrease in the viscosity. During the storage, the values of the titratable acidity, viscosity and whey separations of experimental yogurts increased, while pH of the yogurts decreased significantly (P < 0.01). Yogurt with 10 kg/100 kg fruit paste and 10 kg/100 kg sugar was more acceptable and high scored with respect to overall acceptability value by panelists; however the result was not significant statistically.

Commercial blueberry production has been a viable industry throughout the world for 95 years; because of blueberry is a good source of antioxidant. Blueberries are especially rich in anthocyanin, a flavonoid with potent antioxidant capacity. The aim of this study was to compare the phenolic quantities, antioxidant activities, anthocyanin, sugar and phenolic compounds of blueberries produced in Turkey with those of similar blueberry varieties produced around the world. As a result of the conducted analysis, the total phenolic content (TPC) amount found in the berries was 77.26-215.12 mg GAE/100 g, the total flavonoid content (TFC) was 30.44-91.69 mg QE/100 g and the total anthocyanin content (TAC) was 43.03-295.06 mg c3-GE/100 g. Examining the antioxidant activities of the berries, DPPH between 1.10-5.65 mg/ml, FRAP between 454.93-36832.96 µmol troloks/100 g, β-Carotene between 40.66-86.48%. It was determined that the natural berries contained much more phenolic compounds and higher antioxidant activity than that of the cultivars The result of HPLC analysis, chlorogenic acid is determined to be the dominant compound in all berries. Furthermore, fructose and glucose are found in all fruits in different quantities while sucrose is found in certain varieties of berries as well. At the end of the performed study the data indicate that wild and cultivars of blueberries are rich sources of antioxidants for local as well international industries importing this fruit for food processing and enormous products.

Red cabbage is an attractive vegetable with its rich anthocyanin content, antioxidant potential, and coloring properties. The aim of this study was to determine the properties of lyophilized red cabbage water extract (LRCWE) obtained from fresh red cabbage and the usability of different ratios (0%, 0.4%, 0.6%, 0.8%, 1.0%, and 1.2%) of this extract in the production of pastirma cemen paste. LRCWE had high total phenolic content, anthocyanin content, and antioxidant activity properties. The results showed that besides the increased total phenolic content, anthocyanin content, and antioxidant potential of pastirma cemen paste, the addition of LRCWE significantly improved the desired redness (a*) and consumer acceptability compared to control samples. The best results in terms of redness, functional, bioactive, and sensory properties were determined in cemen pastes containing 1.0% and 1.2% LRCWE. In conclusion, the utilization of 1.0% and 1.2% LRCWE can be recommended as an alternative natural additive to synthetic colorants used in the production of pastirma cemen paste and threatening human health. Practical applications Pastirma is a meat product produced by the salting/curing, the 1st drying, 1st pressing, 2nd drying, cemening and the final drying processes of the whole muscle or muscles. “Cemening” is defined as keeping the meat in a cemen paste prepared with various materials for a certain period of time and then covering the outer surface of the meat with this paste. Cemening is an important stage affecting the quality features of pastirma. Synthetic dyes that threaten human health are added to the cemen paste to improve the color properties of the pastirma. The results of this research could offer an alternative to the use of colorants produced from natural sources instead of synthetic dyes for pastirma providers and contribute to the nutrition of consumers with healthier and safer meat products. In this way, functional properties of meat products processed as pastirma shall be increased.
