High Purity CAS 90-80-2 Delta-Gluconolactone
||White crystalline powder
The Introductction of Delta-Gluconolactone :
1. GDL is a kind of excellent multifunctional food additive. white crystalline granule or powder, easy to dissolve in the water,white crystalline powder, almost odorless,freely soluble in water(60g/ml),has a slightly sweet taste, then sour, sparingly soluble in ethyl alcohol(1g/100ml),almost insoluble ether. Upon addition to water readily forms an mixture of the lactone gdl and gluconic acid.1% solution ph is 3.5,after 2H,PH is 2.5,about 153ºC decomposition.
2. Glucono delta-lactone (GDL) is a naturally-occurring food additive used as a sequestrant, an acidifier, or a curing, pickling, or leavening agent. Pure GDL is a white odorless crystalline powder. Glucono-delta-lactone, upon addition to water readily forms an equilibrium mixture of the lactone GDL and gluconic acid. GDL is commonly found in honey, fruit juices, and wine. Being acidic, it adds 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 is equivalent to one gram of sugar.
The Application & Function of Delta-Gluconolactone :
1. tofu coagulant
GDL is used as a protein coagulant to produce tofu. The texture of tofu is white and tender, the bitter taste of useless brine or gypsum, no protein loss, high tofu rate, and convenient use. In view of the slightly sour taste of tofu when GDL is used alone, GDL and CaSO4 or other coagulants are often mixed in a ratio of 1:3 to 2:3, the amount of which is 2.5% of the weight of dried beans, and the temperature is controlled at about 4 °C. good results.
2. milk gelling agent
Mainly used in the production of yogurt or cheese. In industrial use, the gel strength of the milk formed by acidification with GDL is about twice that of the fermented type. The amount of the gel is about 0.025% to 1.5% in the milk to make the product meet the needs. The curd pH, and the bovine milk gel prepared by incubating at 30 ° C when added with 3% has a similar structure to the gel produced by lactic acid fermentation.
The use of GDL for luncheon meat and canned pork can increase the effect of the coloring agent, thereby reducing the amount of toxic nitrite, and the GDL also has an emulsification effect, antiseptic effect, etc., thereby improving the quality of the canned meat. The maximum dosage is 0.3%.
4. an acidifier
GDL can be added to vanilla extract, chocolate, banana and other sweet sherbet and jelly. It is the main acidic substance in the composite leavening agent. It can slowly produce carbonic acid gas and can produce unique flavors.
In addition, GDL can also be used as a chelating agent in the dairy industry, preventing the formation of milk stone and tartar in the beer industry; as a protein south flocculant in the treatment of industrial wastewater containing protein; as a leavening agent is also widely used.
