Q & A
What was the significance of sugar during the American Revolution?
-Sugar played a crucial role during the American Revolution as it helped turn the tide in favor of the American colonies. It was a valuable commodity that influenced economic and political decisions, contributing to the strained relations with Britain and ultimately the war for independence.
Why was sugar important to Napoleon?
-Sugar was important to Napoleon because he knew that without it, his fortunes would sour. The British blockade during the Napoleonic era cut off sugar from the West Indies, making it scarce and valuable in France, which was heavily dependent on sugar.
How much sugar does the average American consume annually?
-The average American consumes 43 pounds of sugar a year.
What is the significance of sugar in the global economy?
-Sugar is one of the few substances, like oil or grain, that significantly influences the global economy. It is produced in 121 countries with an annual production of over 150 million tons, indicating its widespread importance.
What is the process of growing sugarcane in Hawaii?
-Sugarcane in Hawaii is grown from clones, not seeds, by cutting the existing adult plant into pieces. The hybrid cane takes two years to mature, resulting in high sugar content and stalks that can reach up to 30 feet in height. The crops are then burned briefly to remove dead leaves and a waxy coating before harvesting.
How is sugar extracted from sugarcane in a factory?
-In a factory, sugarcane undergoes a cleanup operation to remove soil and debris. It is then chopped into fine pieces and passed through a hammer mill to separate the liquid from the fiber. The juice is clarified by adding lime, which helps settle out suspended solids. The clear juice is concentrated by boiling it multiple times to remove water. Crystallization is induced by adding finely-divided sucrose crystals, which grow as more sucrose deposits on them. The mixture is then spun in centrifuges to separate the sugar crystals from molasses.
What is the difference between sugar production from sugarcane and sugar beets?
-Sugarcane requires tropical weather and is grown in areas like Hawaii and the Caribbean, while sugar beets flourish in cooler climates and are grown in places like Europe, Asia, and North America. Although the initial growing and extraction processes differ, the final sugar product from both plant species is virtually identical.
How does the sugar industry contribute to the production of ethanol?
-The sugar industry contributes to the production of ethanol by converting sugar into a motor fuel called ethanol, which is primarily alcohol. This process involves fermenting the sugar-rich liquid from sugarcane or sugar beets for six hours, followed by distillation to produce ethanol.
What is the significance of molasses in the sugar industry?
-Molasses is a thick, liquid byproduct of sugar production that is separated from crystallized sugar in a centrifuge. It can be sold as food, cattle feed, or used as a fermentation source for the rum industry. Molasses also plays a role in the production of ethanol, as it can be further processed to extract more sugar.
How does sugar impact the environment and contribute to renewable energy?
-Sugar production can have a positive impact on the environment by providing a source for renewable energy. Bagasse, the fibrous residue from sugarcane, can be used to generate steam and electricity, reducing dependency on fossil fuels. Additionally, burning sugar-derived ethanol is considered carbon neutral, as the carbon dioxide released would have been emitted naturally by the decaying sugar plants.
What are some potential future applications of sugar?
-In addition to its traditional uses, sugar is being researched for potential applications in the pharmaceutical industry. Scientists are experimenting with using sugarcane as a host for growing human proteins, which could lead to lower-cost and safer production of medicines.
