Ultrasonikasyon uygulanmış buğday çimi suyundaki seçilmiş prebiyotik ve probiyotiklerin davranışları

In recent years, wheat (Triticum aestivum) grass and its juice become very popular in United States, Europe and other developed countries. Wheat grass juice contains many beneficial compounds and is defined to possess important effects such as anti-inflammatory, cardiovascular protection, anticancer and antiulcer. In this study, selected prebiotics, probiotics and ultrasonication treatments were combined to increase the functionality of wheat grass juice. Ultrasonication is a non-thermal process that uses sound waves with frequencies higher than the limit for human hearing. Leek and persimmon are potential prebiotic sources containing antimicrobial substances. Probiotics, especially, L. reuteri has an antimicrobial substance which is "reuterin". Combination of prebiotics (leek and persimmon) and probiotics (L. reuteri and L. acidophilus) with a ten minutes of 90 dB amplitude at 24 kHz frequency of ultrasound treatment resulted an effective inhibition against total mesophilic aerobic bacteria, yeast-mold and E.coli compared to control. Lactic acid bacteria were increased with treatments of ultrasonication process. The main chemical and physical properties of wheat grass juice were found to be significantly different between prebiotic-probiotic containing and 90 dB amplitude at 24 kHz frequency of ultrasound treatments. The sugar content of wheat grass juice was increased with prebiotic-probiotic containing treatment groups on the other hand no difference was observed in protein with respect to the control.
