Roses with Powdery Mildew: Getting Rid Of Powdery Mildew On Roses
The first thing that comes into your mind when you hear the word “powdered” is something that would make your eyes water and cause you to cough. However, it’s not just any old powdered sugar or corn syrup; it’s actually a highly refined form of sugar called granulated white cane juice (WDCJ).
Powdered WDCJ is used in many different products such as candies, chewing gum, toothpaste, shampoo and even some cosmetics.
Powdered WDCJ is made from cane sugar and then processed through a chemical process before being packaged into various forms. Most commonly it’s found in granules or tablets which are often sold under brand names like Sweet’N Low and Nature Valley.
These products are usually labeled as containing no added sugars or high fructose corn syrup. Powdered WDCJ is also known as pure sugar.
However, there are other types of powdered WDCJ available such as those that contain only natural sugar, those that have less than 0.5% sucrose (table sugar), and others that do not contain any sweetener at all!
You may wonder why these kinds of products exist if they don’t contain any added sugars?
It’s because they’re typically used in specific kinds of food such as fruits and vegetables and others are used in baking goods. For example, pure powdered WDCJ is typically found in canned fruits as a preservative. In addition, it’s also used in preserves, jams and jellies.
While all types of powdered WDCJ can be used for both cooking and baking needs, those that contain less than 0.5% sucrose (table sugar) are typically used for non-compound sweeteners.
This means that they are not used in recipes that call for the others, but rather on their own or with other sweeteners such as stevia or Splenda.
Powdered WDCJ that contains no added sugars is sometimes referred to as sugar alcohols which are made by processing different types of sugars. These types of sweeteners have a much lower caloric value as well as a lesser effect on blood sugar levels.
It’s also thought to be lower on the glycemic index than regular sucrose but is known to cause diarrhea and other gastrointestinal issues for some people.
Natural powdered WDCJ contains no added sugars and are typically made up of sugars like maltose and lactose. These types of sweeteners are used in specialty and diet products.
For example, those who are lactose intolerant can tolerate natural powdered WDCJ since it contains the sugar lactose which is often removed during the processing of regular table top sugars.
In addition, pure powdered WDCJ falls under this category as well and is sometimes referred to as barley malt or molasses sugar.
