2.5. Traditional foods

This grape cultivar, which is generally consumed as a table, is also used in human

nutrition in the form of products obtained by processing grape must in different

ways (vinegar, molasses, sausage, pulp, bastik, meatballs, etc.). Additionally, a

product called Saruç, which is a traditional product that is dried by hanging on

a rope and then offered for consumption after the walnuts are placed into the

grapes that are cut into two, has been made from the ‘Karaerik’ grape cultivar

since ancient times in the region. With its high nutritional content and a special

aroma, the product, which is in high demand in the region, can find buyers at a

very higher price. In studies on Saruç, its pH, ash content, total soluble solids

(TSS), dry matter, moisture, and skin color values and chemical properties (total

acidity, protein, N, P, K, Ca, Mg, S, Fe, Zn, Cu, Na) was detected. Based on the

results of the study, it was determined that 185 g of raisins were obtained from

one kg of fresh grapes, and 1 kg of Saruç consisted of 685 g of raisins and 315

g of walnuts. In addition, according to the results of the analysis, the pH, TSS,

protein, P, Ca, Cu values of the obtained Saruç were found to be 3.13, 5.77%,

7.48%, 225.20 mg, 59.40, Cu 0.66 mg, respectively (Kalkan et al., 2012). On

the other hand, though it is known that vinegar and molasses are made from this

grape cultivar in the region, studies on this subject have not been found in the

literature.

2.6. Improving the grape quality

In this context, the effects of two different organic biostimulants containing

mineral and organic compounds (seaweed-based) on the grape quality of

‘Karaerik’ grape cultivar were investigated by Köse & Gülyüz (1999) in

field conditions. Both mineral and organic compounds have been reported to

reduce TSSC and reducing sugars in the must and total dry matter of the berry.

Compared to the control, the effects of biostimulator applications decreased the

rate of fruit falling in all treatments and all of these applications showed similar

effects. In addition, while Proton application did not have an effect on the spilled

berry rate in the study, it was determined that Maxicrop applications other than

1250 mg kg -1 reduced the spilled berry rate (Köse & Güleryüz 1999). On the

other hand, three grapevine training systems (vertical shoot positioning-shaped,

Y-shaped and traditional Baran system) and three different (75, 100, and 125 cm)

trunk heights were compared for their effects on skin color, berry weight, cluster

weight (g), TA%, pH, TSS%, MI, organic acid, sugar, antioxidant activity

(FRAP) and vitamin C as well as total and individual phenolic compounds
