Storage method

Plastic bag coated with kraft paper bag, sealed packaging, stored in a cool and dry place. Do not store together with toxic and polluted items.

Synthesis method

1. Erythritol can be extracted from seaweed, moss and certain grasses. It can be synthesized artificially by reacting butylene glycol and hydrogen peroxide. Among them, butene diol is produced by first making 2-butyne-1,4-diol from acetylene and formaldehyde, then mixing its aqueous solution with Raney nickel, adding inhibitor ammonia, and hydrogenating it at about 0.5MPa. .

2. Made from wheat, corn and other starches through safe and appropriate food-grade hypertonic yeasts such as Moniliella pllinis, Candida lipolytica or hyphomycetes ( After enzymatic fermentation of Tricho sporonoides megachilensis) at high concentration (>450g/L), the fermentation mash is heated and sterilized, filtered and then purified by ion exchange resin, activated carbon and ultrafiltration, crystallized, washed and dried. The general yield is about 50%.

3. After starch milk is enzymatically decomposed into glucose, it is fermented by hypertonic yeast at high concentrations and then concentrated, crystallized, separated and dried.


It can be used as diluent, humectant, flavor enhancer, texture improver and molding aid for low-calorie sweeteners and high-intensity sweeteners. It can also be used in chocolate, baked products, soft drinks, solid drinks, candies, etc. It is especially suitable for the production of food that avoids moisture.
