White crystal or powder, odorless, sweet and bitter, the sour taste. Melting point of 150 ~ 152 ℃, and then decompose. Slightly soluble in ethanol, soluble in water, insoluble in ether. Hydrolysis in aqueous solution, glucose solution becomes acid, and the balance of the lactone.
Lactone: a new non-toxic food additive in the food industry are used as sour agent, preservative, preservatives, proteins and other coagulant. Lactone is a soluble in water at 25 ℃ eels slow decomposition of white crystals.
In the New Year, HuiYang drastic reform of company production lines, production spend sodium gluconate, glucono-delta-lactone new projects, focusing on the completion of the annual output of ten thousand tons GDL production workshop.
