DELTA-GLUCONOLACTONE CAS 90-80-2 is an ester formed by dehydration between the carboxyl group of gluconic acid and the hydroxyl group in the molecule. It has a sweet taste different from gluconic acid. DELTA-GLUCONOLACTONE CAS 90-80-2 decompose at 153 oC[ α] D20+61.7°(C=1). Soluble in water, hydrolyzed to gluconic acid in aqueous solution, and δ and γ The two lactones form an equilibrium mixture.
DELTA-GLUCONOLACTONE CAS 90-80-2 is used as food additive, sour agent, fruit juice, beverage and jelly; As a coagulant, glucolactone is a food coagulant allowed by China's regulations. DELTA-GLUCONOLACTONE CAS 90-80-2 is used for soybean protein and milk protein. When it is used as tofu coagulant, 0.25% ~ 0.3% is added to soybean milk. Compared with calcium sulfate, DELTA-GLUCONOLACTONE CAS 90-80-2 has better water solubility.
DELTA-GLUCONOLACTONE CAS 90-80-2 can be evenly dispersed in soybean milk. The tofu made is delicate and often used with calcium sulfate; As a bulking agent, compared with other acids, DELTA-GLUCONOLACTONE CAS 90-80-2 is not easy to react at low temperature. It turns into gluconic acid after heating, and then reacts with sodium bicarbonate to produce carbon dioxide bubbles with uniform and fine foaming. DELTA-GLUCONOLACTONE CAS 90-80-2 can be used as a bulking agent for biscuits, bread, etc., especially for cakes.
