Abstract

The invention discloses a propylene glycol alginate emulsifier production method. The propylene glycol alginate emulsifier production is characterized by comprising the main steps: adding 30kg of calcium alginate, 40 to 45kg of sodium alginate and 50 to 53kg of alginic acid into a reaction kettle; introducing excessive epoxypropane gas under 60 to 65 DEG C to react for 50 to 70min; cooling to 10 to 13 DEG C; vacuum filtering; washing with an ethyl acetate solution for 1 to 2h; recrystallizing in a cyclohexane solution; drying and smashing; finally, obtaining a finished product.

Description

technical field [0001] The invention relates to a compound production method, in particular to a production method of a propylene glycol alginate emulsifier. Background technique [0002] Propylene glycol alginate is mainly used as a thickener and emulsion stabilizer. It can be used as an emulsification stabilizer in emulsified flavors, with a maximum usage of 2.0g / kg; it can also be used in ice cream, with a maximum usage of 1.0g / kg; it can also be used in beer and beverages , the maximum dosage is 0.3g / kg; it can also be used in dairy products, fruit juices, the maximum dosage is 3.0g / kg; it can also be used in chewing gum, chocolate, condensed milk, hydrogenated vegetable oil, sauces and vegetable protein beverages, the maximum dosage is 5.0g / kg kg. Most of the existing production methods are relatively complicated. Propylene glycol alginate is used as an emulsifier. The pros and cons of its production methods have important economic significance for improving product qu...
