What enzymes are used in slimming foods?
A carbohydrase can be used to convert starch syrup into sugar syrup. An enzyme called isomerase can convert glucose in sugar syrup into fructose syrup. Fructose is much sweeter than glucose. A small amount of fructose in a food can replace a larger amount of glucose without losing the sweet taste. This is useful in preparing slimming food since a small amount of fructose is less fattening than a larger amount of glucose.

What enzyme changes glucose to frutose?
The enzyme responsible for converting glucose to fructose is glucose isomerase. It catalyzes the reversible isomerization of glucose to fructose. This enzyme is commonly used in the production of high-fructose corn syrup.
Is high fructose corn syrup?
High fructose corn syrup is a caloric sweetener made from corn. It has a composition that is similar to sugar or sucrose. The are two types of high fructose corn syrup commonly used in foods and beverages. HFCS-55 is made up of 55% fructose with the other 45% mainly glucose. It is commonly used as a sweetener in soda. HFCS-42 is made up of 42% fructose and the remaining 58% is primarily glucose. It is used in condiments, baked goods and fruit-flavored beverages.
How is high fructose corn syrup produced?
High fructose corn syrup (HFCS) is produced by processing corn starch, which is derived from corn kernels. The starch is first liquefied with heat and enzymes, converting it into a syrup. Then, specific enzymes, such as glucose isomerase, are added to convert a portion of the glucose in the syrup into fructose. The resulting mixture, which contains varying levels of fructose, is then concentrated and purified to create HFCS, commonly used as a sweetener in various food and beverage products.
Why is high fructose corn syrup used in food products instead of sucrose?
Corn syrup is cheaper than cane sugar.
Difference between high fructose corn syrup and invert sugar?
Functionally there is no difference. Both are ~50% glucose and ~50% fructose (HFCS can vary between 92% fructose and 42% fructose, most HFCS used in food is between 42% and 55% fructose, the balance being glucose). The following descriptions are by necessity simplified, but will serve to demonstrate the important aspects of the production of the two products. Invert sugar is sucrose (a molecule of fructose bonded to a molecule of glucose) mixed with a bit of water and heated. The water and heat cause a splitting of the sucrose molecule called hydrolysis. Often catalysts are added to speed the splitting, acid being a common catalyst (lemon juice, cream of tartar, etc.). The resulting syrup is free glucose and fructose in a bit of water. HFCS is made by taking corn starch (starch is a long chain of glucose molecules) and splitting it up into glucose. This is done by enzymes. The result from this is corn syrup, much like the corn syrup you can purchase in a supermarket. To turn the corn syrup into high fructose corn syrup it is mixed with a another enzyme which changes the glucose into fructose. The resulting syrup is usually 92% fructose. Fructose is much sweeter than glucose (~1.8 times as sweet). To make a syrup that resembles the sweetness of invert sugar the 92% (HFC92) HFCS is mixed with corn syrup to get a final percentage of fructose around 42%-55% (HFC42 and HFC55). All the enzymes used in the process are removed before the syrup is used in food. While the two processes are different, it is obvious that the final product is virtually, and metabolically, identical. Jonathan Davey A.O.S. Culinary Arts, B.S. Food Science
Why does Isomerase convert glucose syrup into fructose syrup?
Glucose or mannose or fructose are interconverted in presence of base. The common intermediate is the formation of an enediol, CH(OH)=CH(OH)--- , between C1 and C2. This rearrangement is also known as Lobry de-Buryn Van Ekenstein rearangement.
How is high fructose corn syrup metabolized in the body and what impact does it have on overall health?
High fructose corn syrup is metabolized in the body similarly to table sugar. It is broken down into glucose and fructose, which are used for energy. However, excessive consumption of high fructose corn syrup can lead to health issues like obesity, diabetes, and heart disease. It is important to consume it in moderation to maintain overall health.
Why inversion of sugar is done in pharma industry?
Sucrose in syrup or other liquid formulations on storage converted into glucose and fructose(1:1) with lose of a molecule of water this is called inversion of sugar and solution becomes concentrate this is reason instead of sucrose inverted sugar syrup is used in formulation
Common name of fructose?
A common name for fructose is corn syrup. Fructose is the sugar that is found in fruit. Corn syrup is used in cooking. If corn syrup is used in a recipe, it will usually call for less sugar to be added.
