How Is Sugar Made?

Sugar cane and sugar beets produce most of the sugar we use. Even though these plants grow in different climates, sugar cane in the tropics and sugar beets in temperate zones, once their sugar is refined, there is very little difference between the two.

Sugar cane stalks grow from old stalks planted in the ground. When their growing season is over (7 to 22 months) and the stalks are 7 to 15 feet tall, they are cut and taken to a sugar mill.

At the sugar mill, machines wash, cut, and shred the stalks into a pulpy mass. With water continually sprayed on it, this pulpy mass is crushed between rollers to squeeze out the sugary juice, called cane juice.

The liquid, now a dark grayish-green color, is heated to its boiling point, and chemicals are added to remove impurities. Next, the juice is placed in huge tanks to evaporate, leaving a thick syrup. This syrup is heated to remove more and more water until crystals form. These crystals must be separated from the syrup, so they are put into a centrifuge machine which spins it around rapidly.

The sugar which is left inside the machine’s cylinders is called raw sugar. In this form, the sugar has uses to some manufacturers, but to make it suitable for food, it must go to a refinery. There, it is dissolved, treated with chemicals, filtered, crystalized once more, and allowed to solidify, this time into pure white sugar.

Beet sugar is produced much the same way as cane sugar. The beets are sliced and soaked with chemicals to form a sugary syrup. This syrup is also filtered and evaporated until it, too, becomes pure white sugar.

Adding together the table sugar we use with soft drinks, baked goods, candy, canned fruits, jellies, and desserts, an average person in the United States eats 100 pounds of sugar a year!

    Wow, I thought sugar was a natural product. It’s about as man made as you can get, apparently.

    Powdered lime is added to the juice. Dissolved in the juice, it binds with impurities and settles out mud & other impurities. The lime does not remain in the juice, but stays attached to the impurities.

    Other chemicals used are dextranase to reduce the amount of dextran in the raw sugar and chlorine to sanitize the mill.

    Sugar: Is the Calcium extracted during it’s production? Does constant heating of the natural syrup extract the calcium and leave the crystal ‘wanting’ to reattach itself to form of calcium when ingested by humans?

    How to make sugar crystals into different granulation… coarse, fine and extra fine? Is it control by the degree of evaporation (stop when desired size of sugar crystal is obtained)?

    Theres a video called Jimmy’s Factory that shows the process, check it out

    Refined cane Sugar is an evil adictive drug used by the elite to manipulate control and….. Kill us.

    “The primary distinction between cane sugar and beet sugar, other than being derived from different plants, is the processing method. Unlike beet sugar, cane sugar processing typically takes place at two locations, the sugar mill and the refinery. During the final purification process, cane sugar is filtered through activated carbon (charcoal) which may be of animal, vegetable, or mineral origin. This step is unnecessary for beet sugar and therefore is never done.”
