Answer:
Colorado river
Explanation:
The Grand Canyon is usually referred to as the large and beautiful geological landform that is formed by the continuous carving of the rocks due to the flow of the Colorado River through the canyon. It is near about 450 kilometers long and has a width of about 6.5 to 30 kilometers. This canyon covers a large area in the north-western part of Arizona in the United States.
The main agent for the cutting down of rocks here is the water. According to the research, this canyon is about 70 million years old, and the river Colorado has been flowing through this canyon from about 5-6 million years back.
Answer:
The effects of supercritical CO2 (SC-CO2) on the microbiological, sensory (taste, odour, and colour), nutritional (vitamin C content), and physical (cloud, total acidity, pH, and °Brix) qualities of orange juice were studied. The CO2 treatment was performed in a 1 litre capacity double-walled reactor equipped with a magnetic stirring system. Freshly extracted orange juice was treated with supercritical CO2, pasteurised at 90°C, or left untreated. There were no significant differences in the sensory attributes and physical qualities between the CO2 treated juice and freshly extracted juice. The CO2 treated juice retained 88% of its vitamin C, while the pasteurised juice was notably different from the fresh juice and preserved only 57% of its vitamin C content. After 8 weeks of storage at 4°C, there was no microbial growth in the CO2 treated juice.
