Description
Technical field
The present invention relates to a kind of production method that is used as the composite phosphate of foodstuff additive.
Background technology
The production method of known composite phosphate is that various additives as raw material are carried out simple and mechanical mixing.Though this production method is simple, physical properties defective such as moisture absorption, the caking etc. of various additives still exist in the product that generates.Product is after entering food, and owing to the secondary reaction that temperature, acidity, moisture content etc. bring out, the meeting that has produces stack toxicity, and mix owing to be that machinery is simple, can only reach the distribution of crystal level, can not reach intermolecular homogeneous phase, its synergistic effect is difficult to give full play to.
Chinese patent ZL93109096.2 discloses a kind of production method of polyphosphate compound salt series, and this method is that various additives as raw material are carried out secondary treatment, i.e. dissolving, crystallization and dry.But owing to be that secondary processing and product have a certain amount of crystal water, give to produce with using and all bring very big inconvenience, and the homogeneous phase that secondary treatment also is difficult to reach molecular level mixes, synergistic effect can not be given full play to.
Summary of the invention
The objective of the invention is to provide a kind of production process of chemically composited phosphate, and the homogeneous phase that the product of this production method gained can reach molecular level mixes, and can not produce stack toxicity after entering food, can give full play to synergistic effect.
The object of the present invention is achieved like this: add the phosphorus bronsted lowry acids and bases bronsted lowry in the neutralizing well while stirring, and control proportioning or degree of neutralization, after question response is abundant, feed liquid is transferred in the storagetank, spray-dried then, polymerization is also controlled the material temperature and is promptly generated chemically composited phosphoric acid salt at 100～300 ℃.
Can also add organic acid, phosphoric acid and organic acid added in 1: 1 in molar ratio or 1: 2.
Described organic acid is one or more in Sorbic Acid, propionic acid and the lactic acid.
Described degree of neutralization is that pH value is 3.8～9.0.
Described alkali is one or more in yellow soda ash, salt of wormwood, lime carbonate and the aluminium hydroxide, and the mol ratio of yellow soda ash and salt of wormwood is 1: 1～9: 1, and the mol ratio of yellow soda ash, lime carbonate, aluminium hydroxide is 5: 2: 2.
The present invention is the composition according to the synthetic different mol ratio of the ingenious preferred group of different purposes, giving full play to the synergistic effect between phosphoric acid salt, poly-phosphate, organic acid salt and the metallic element, thereby develop the chemically composited type additive of a series of high-quality higher level suitable different purposes.
Proportioning raw materials of the present invention is to calculate according to the required theoretical molecular composition that obtains product of reaction, and only be similar to this theory composition actual the composition.The particle diameter of composite salt is looked purposes and is different.Two kinds of general branch particle and fine powders.
Because the factor of chemical reaction influence is a lot, situation of the present invention is particularly special, thus the composition of actual product, can only the approximation theory composition.During chemically composited phosphoric acid salt of the present invention was formed, the mol ratio of phosphoric acid salt, poly-phosphate, organic acid salt and metallic element allowed the little scope that departs from, and does not influence its performance.
The present invention utilizes the phosphorus bronsted lowry acids and bases bronsted lowry to carry out neutralization reaction, and strict control proportioning or degree of neutralization and dry polymerizing condition, directly generation is a series of has the phosphoric acid salt of different metal element ratio, different polymerization degree ratio, the molecular level homogeneous chemical complex of poly-phosphate, thereby develops all remarkable chemically composited phosphoric acid salt of enhanced of a series of biologies, physics, chemical property.Can also directly make the organic acid that is insoluble in water participate in generating double salt, not only soluble in water but also non-hygroscopic deliquescence.This chemically composited phosphatic biology and physical and chemical performance obviously are better than single phosphoric acid salt or mixed phosphate, and the homogeneous phase that product can reach molecular level mixes, and can not produce stack toxicity after entering food, gives full play to synergistic effect.Product is widely used in food, as meat product, fishery products, rice product, milk-product, beverage etc. as additives such as antibacterial and mouldproof, anti-oxidant, quality-improving, PH buffering, nutritional fortifications.This production method uses existing production unit to produce, and method is simple, and it is convenient to implement.
