3.1. Raw Materials
3.1.1. White Grape Juice Samples
CHAPTER 3
MATERIALS AND METHODS
Pasteurized white grape juice samples made from seedless Sultana variety used
in this study were purchased from a company in Turkey (Kavaklıdere Winery, Ankara).
Pasteurized samples were selected in order to be sure that background microflora did
not affect the run of experiments. All samples were from the same batch and stored at
4°C in the refrigerator.
3.1.2. Preparation of Freshly Squeezed Orange Juice Samples
Fresh oranges from Washington variety used to obtain orange juice were
purchased from a local market in İzmir and kept in the refrigerator. Before juice
extraction washed oranges were cut into half and pressed by using a household table top
citrus juice extractor (Arçelik, Robolio, İstanbul).
