Nutritional Analysis of Red-Purple and White-Fleshed Pitaya () Species.

Pitaya is one of the most preferred and produced tropical fruit species recently introduced to the Mediterrranean region in Turkey. Due to its nutritional fruits with high economic value, the popularity of pitaya increases steadily in Turkey as an alternative crop. No detailed nutritional analysis has been undertaken in Turkey so far on fruits of the pitaya species.

Comparison of Polyphenol, Sugar, Organic Acid, Volatile Compounds, and Antioxidant Capacity of Commercially Grown Strawberry Cultivars in Turkey.

The aim of this study was to compare certain important fruit quality parameters such as sugars, organic acids, total phenolic content, antioxidant capacity, and volatile compounds of 10 commercial strawberry cultivars grown in the research and experimental area in Yaltir Agricultural Company located in Adana provinces of Turkey. As for the sugar content of strawberry fruits, fructose was identified as the dominant sugar and the highest value (4.43%) was found in the cultivar "Rubygem".

Total phenolics, antioxidant activities and fatty acid profiles of six species.

In present study, total phenolic compound, antioxidant activities and fatty acids of several species collected from different regions of Turkey were determined. Six species were detected, namely (HT562), group (HT565, HT592, HT662, HT699), (HT682), (HT698), (HT667, HT681) and (HT704). The highest phenolic content was determined in the collection numbered as HT565 (281.
