Gluconolactone Application:1. Used as a tofu coagulantGDL 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. Used as milk gelling agentMainly 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.3. Used as a quality improverThe 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. used as an acidifierGDL 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.Packing &Shipping:Liquid:
