Fructose (fruit sugar) is a simple monosaccharide which we can find in many plants.  This is one of three dietary monosaccharides, along with glucose and galactose, which are absorbed directly into the bloodstream during digestion.  Fructose was discovered in 1847. by French chemist Pierre-Augustin Dubrunfaut.  Clean, dry fructose is of crystalline structure, very sweet (sweetest of all sugars, twice sweeter than table sugar in crystal form), white, odorless, most soluble of all sugars.  In the absence of insulin, it has the ability to convert into glucose in the liver, thus contributing to the growth of blood glucose.  Unlike sucrose and glucose. fructose does not cause sudden changes in blood glucose levels (what can cause disruption of metabolic control with diabetics), but is absorbed much more slowly, causing only minor changes in blood glucose levels.  Hence it is used as a sweetener for people with diabetes.  It is found in honey, fruits, grapes, flowers, berries, and most root vegetables.  In plants, fructose can be present as a monosaccharide and / or as a component of sucrose.
Commercially, fructose is usually derived from sugar cane, sugar beet and corn. There are three commercially important types.  Crystalline fructose is a monosaccharide, dry and of high purity.  Corn syrup with high fructose content is mixture of glucose and fructose as monosaccharides.  Sucrose is third form.  All forms of fructose, including fruits and juices, are usually added to foods and beverages to improve flavor and texture as well as for achieving desired color in some cooked foods.  Fructose shows sweetness synergy effect when used in combination with other sweeteners.

Aspartame is an artificial sweetener in the form of granules or powder.

It is sweeter than sugar approx. 200 times and used as its replacement in production of food and beverages.

Monosodium glutamate, also known as sodium glutamate and MSG, is the sodium salt of natural non-essential amino acid of glutamic acid.

In its pure form, it appears as a white crystalline powder.

Ascorbic acid, better known as vitamin C, is powder or crystal of white to pale-yellow color with antioxidant properties.

The name is derived from a (“not”) and scorbutus (“scurvy”), disease caused by deficiency of vitamin C.

Glucose is a simple sugar, monosaccharide, and is one of the most important carbohydrates.

It is used as an energy source in animals and plants. It is also one of main products of photosynthesis and serves as a starting substance for respiration.

At room temperature, citric acid is a white crystalline powder, easily soluble in water.

It can be obtained from lemon, but is usually derived from sugar by fermentation, using molds.

Carrot is a root vegetable of, usually, orange, purple, red, white or yellow color.

In ancient times, carrot was used as a medicinal herb because it contains substantial amounts of vitamins and various minerals.

Tomato concentrate is a thick paste made from mature tomatoes from which seeds and skin have been removed.

There are 2 production processes – “hot” and “cold break“. The “Hot break” process heats tomatoes to about 100° C, “cold break” occurs at about 66° C..

Tomato powder is obtained by drying tomato concentrate in several ways.

Commercially, most common are AD (“air dried”) and SD (“Spray Dried”).
