Özet:

 


Rosehip is a widespread wild plant that has been used in food products
such as tea, jams, marmalades, nectar. It plays crucial role in traditional
medicine because of valuable bioactive compounds including mainly phenolic
compounds and ascorbic acid. The present study deals with biochemical and
sensory properties of rosehip nectar produced from fresh and sun-dried fruits. The
studied rosehips were collected from Gumushane and its neighboring vicinities.
The fresh and dried rosehips were pulped at different temperature conditions as
65, 90, 100 ºC and then nectared. Total acidity, total soluble solid contents,
pH, total phenolic, ascorbic acid content (vitamin C) and sensory properties of
produced nectars were examined. Process temperatures showed statistically significant
effect (p< 0.05) on ascorbic acid
and total phenolic content.  No
differences were found in the acidity and pH between nectar
samples. All nectar samples treated at 65 ºC exhibited the highest ascorbic
acid (56-90 g/100 mL) and total phenolic contents (654.2-894.4 mg GAE/100 mL). Colour and appearance scores of samples obtained at
65 ºC were found higher according to sensory analysis.
