Gluconate Based Technology Products
Glucono Delta-Lactone
Glucono Delta-Lactone is a white crystalline powder and almost odorless. It has a slightly sweet taste, then bitter, and finally sours. The melting point of Glucono Delta-Lactone is 150 – 154℃ (decomposition). It is freely soluble in water (60 g/ mL of water), sparingly soluble in ethyl alcohol (1g / 100 mL of water), and almost insoluble in ether. It can be hydrolyzed into the balanced solution of Glucono Delta-Lactone and Gluconic acid in aqueous solution.
Glucono Delta-Lactone is a multifunctional food additive with following applications:
GLUCONIC ACID
Specifications
Gluconic acid is an organic compound with a molecular formula of C6H12O7. In aqueous solution at neutral pH, gluconic acid forms the Gluconate ion. The salts of gluconic acid are known as “Gluconates”. Gluconic acid, gluconate salts, and gluconate esters occur widely in nature as these compounds arise from the oxidation of glucose. Some drugs are injected in the form of gluconates.
Production
Gluconic acid can be obtained by chemical synthesis, on account of its superior selectively; however microbial production is highly preferred. A series of
Microorganisms under the genus of Aspergillus, Penicillin, Gluconobacter, Pseudomonas, Phytomonas, Achromobacter, Klebsiella, Zymomonas,Acetobacter
have already been used for microbial production of gluconic acid. A yeast-like fungal culture, Aureobasidium pullulans was also known for the production of small amounts of gluconic acid.
Applications
Gluconic acid is a multifunction carbonic acid and it is used extensively in various applications with its physiological and chemical characteristics. It has many applications like:
Used as a raw material for the manufacturing of gluconate salts with minerals like Calcium, Sodium, Potassium, and Manganese etc.
Different Salts of Gluconic acid
The gluconate anion chelates with Ca2+, Fe2+, Al3+ as well as other metals and forms salts. In 1929, Horace Terhune Herric first developed a process for producing the salt by fermentation.
Various gluconate salts with their applications are as follows:
Calcium is an essential element of tissues and blood, which constitutes approximately 10 mg/ 100 mL. The average daily requirement of calcium is 500 mg, however higher amounts are necessary during the periods of growth.
Calcium Gluconate has various applications in pharmaceutical, food, and feed industries.
Applications:
Potassium Gluconate is administered in all cases of potassium deficiencies or in danger of potassium depletion in conditions like diabetic acidosis, diarrhea, and vomiting etc. Potassium chloride is also used but potassium gluconate is highly preferred because of its slight saline taste.
Advantages:
Sodium gluconate has many applications in as below:
Manganese gluconate can be readily formulated into tablets for the treatment of manganese deficiency. It is primarily added to vitamins and mineral dietary preparations to supplement the normal intake in the case of inadequate levels. In feed stuff Manganese Gluconate is added to animals feed to assure adequate manganese ions for balanced diet development.
Manganese gluconate has applications in Pharma, Food, and Feed sectors.
