Why did prices on Eastern goods increase after the Muslims captured Constantinople in 1453?

Taxes were added on each article passing through the area

When the Muslims (Turks) captured Constantinople, they controlled the center of trade. The Muslims took complete control of the Middle East. This shut off the trade routes from Europe to Asia. All goods had to go through Constantinople. They were in control of all trade going in and out Constantinople. Therefore, they placed a tariff on each article that passed through Constantinople. Basically the muslims refused to trade.
