Glucose syrup, also known as confectioner’s glucose, is a syrup made from the hydrolysis of starch. Glucose syrup was first made in 1811 in Agave syrup sugar equivalent by Gottlieb Kirchhoff using heat and sulfuric acid. Depending on the method used to hydrolyse the starch and on the extent to which the hydrolysis reaction has been allowed to proceed, different grades of glucose syrup are produced, which have different characteristics and uses.
The original glucose syrups were manufactured by acid hydrolysis of corn starch at high temperature and pressure. The typical product had a DE of 42, but quality was variable due to the difficulty of controlling the reaction. Before conversion of starch to glucose can begin, the starch must be separated from the plant material. The starch needs to be swelled to allow the enzymes or acid to act upon it. When grain is used, sulfur dioxide is added to prevent spoilage. By heating the ground, cleaned feedstock, starch gelatinization takes place: the intermolecular bonds of the starch molecules are broken down, allowing the hydrogen bonding sites to engage more water.
Glucose syrup can be produced by acid hydrolysis, enzyme hydrolysis, or a combination of the two. Currently, a variety of options are available. Formerly, glucose syrup was only produced by combining corn starch with dilute hydrochloric acid, and then heating the mixture under pressure. Currently, glucose syrup is mainly produced by first adding the enzyme α-amylase to a mixture of corn starch and water. After hydrolysis, the dilute syrup can be passed through columns to remove impurities, improving its colour and stability.
The dilute glucose syrup is finally evaporated under vacuum to raise the solids concentration. Glucose syrup is also widely used in the manufacture of a variety of candy products. American-made processed and mass-produced foods, candies, soft drinks and fruit drinks to increase profit margins. Glucose syrup was the primary corn sweetener in the United States prior to the expanded use of HFCS production.
HFCS is a variant in which other enzymes are used to convert some glucose into fructose. The resulting syrup is sweeter and more soluble. Corn syrup is also available as a retail product. Glucose syrup is often used as part of the mixture that goes into creating fake blood for films and television. Blood mixtures that contain glucose syrup are very popular among independent films and film makers, as it is cheap and easy to obtain.

I am always looking for helpful kitchen gadgets that will make my life easier when I create in the kitchen. Here are some Kitchen Gadgets that you may also find helpful. This recipe is especially for anyone asking is there sugar free chocolate chips.
I must say that since posting this recipe years ago, there has been kind of an explosion in sugar free, or even keto, baking. Unlike today, one time there was just one kind of sugar free chocolate chip available. There are many kinds of sugar free chocolate chips to choose from! I suggest using a chocolate chip that contains the sugar alternative that you prefer most. Also, that chocolate chip should be suitable for baking with as well. I have got to say, sometimes you want a soft cookie and sometimes you simply want a crispy cookie. This cookie is somewhere in the middle since it is a basic recipe.
What you should know is that not using sugar can alter this sugar free cookie. Sugar allows a cookie to hold on to moisture and sugar alternatives just do not have this chemical makeup. I just mentioned that sugar and sugar alternatives may taste alike but, their chemical makeup is different. Here are some more helpful tips for you.
