GDL / Glucono-Delta-Lactone
GDL / Glucono-Delta-Lactone also known as gluconolactone, is a food additive with the E number E575[3] used as a sequestrant, an acidifier, or a curing, pickling, or leavening agent. It is a lactone (cyclic ester) of D-gluconic acid. Pure GDL is a white odorless crystalline powder. GDL is commonly found in honey, fruit juices, personal lubricants, and wine[citation needed]. GDL is neutral, but hydrolyses in water to gluconic acid which is acidic, adding a tangy taste to foods, though it has roughly a third of the sourness of citric acid. It is metabolized to glucose; one gram of GDL yields roughly the same amount of metabolic energy as one gram of sugar. Upon addition to water, GDL is partially hydrolysed to gluconic acid, with the balance between the lactone form and the acid form established as a chemical equilibrium. The rate of hydrolysis of GDL is increased by heat and high pH. The yeast Saccharomyces bulderi can be used to ferment gluconolactone to ethanol and carbon dioxide. The pH value greatly effects culture growth. Gluconolactone at 1 or 2% in a mineral media solution causes the pH to drop below 3.

Acesulfam-K
Acesulfam-K is a calorie-free sugar substitute (artificial sweetener), also known as Acesulfame K or Ace K. It is a food additive and sweetening agent for use in the bakery and beverage industry as well as in diary products.
Beta Carotine (Provitamin)
Beta Carotine (Provitamin) is a yellow-orange food colorant, used in beverages, butter, margarine, dairy products and candies.
Biotin (Vitamin B7 / Vitamin H)
Biotin (Vitamin B7 / Vitamin H) is a B-complex vitamin, also known as vitamin B-7 or vitamin H. It is important in a number of metabolic functions in the human body, including cell growth, the synthesis of fatty acids, and the metabolism of the amino acid leucine. Biotin also assists in the Krebs cycle, through which the body converts food into energy, and in the transfer of carbon dioxide within the body. Intestinal bacteria naturally produce this vitamin, and a deficiency is therefore quite rare.
Agar Agar
Agar-agar, usually seen abbreviated as agar, is a gelatinous substance derived from certain types of red algae, or seaweed. There are a number of uses for it, although most people are familiar with it as the culture medium in petri dishes. This substance is also perfectly edible, and in addition to appearing in regional cuisine, it is also used as a thickening agent in candies and other foods. Since it is derived from plant material, it has the advantage of being suitable for vegetarians, unlike gelatin, which is derived from animal sources.
