Abstract
The invention relates to a liquid titania with good disperse property to be used in food and drug. The invention is characterized in that it is formed by 30-70wt% titanium dioxide, 1-5wt% cellulose, or maltose and/or saccharose, 2-10wt% polyphosphoric acids, sodium salt and methyl glycol disperser, 0.01-1wt% carbowax emulsifier, some water or organic alcohol, therefore, its specific weight is higher than water and solvent pure titanium dioxide, to prepare stable suspension, with less finding and sugar, good disperse property, low viscosity, non antiseptic, and low cost. And the obtained liquid has uniform dispersed antholeucin in pure water and tap water and uniformly dispersed in fatty soluble solution. The invention can save titanium dioxide consumption since it has better disperse property, easy operation and less consumption.
Description
Technical field
The present invention relates to a kind of good dispersion, in particular for the liquid titanium and the preparation method of food, medicine.
Background technology
Food-level titanium dioxide (claiming antholeucin again) is mainly used in the colouring agent of food, brightening agent, and through the toxicity evaluation, it is safe, has no side effect, and the auxiliary type agent that also is used to medicine is dressing for example.The food-grade of solid, pharmaceutical grade titanium dioxide, because dispersed, suspension and homogeneity are poor, in food, medicine batching, are difficult to even mixing, not only influence result of use, and cause the waste of titanium dioxide.Obtaining liq, because its proportion very easily precipitates much larger than aqueous solvent and pure lipoprotein solution, charged calcium ions and magnesium ions in the water especially; Make the titanium white powder particulate more be prone to gather deposition; Through being difficult to make homodisperse suspension, be difficult to equally evenly mix with batching, not only bring difficulty to use; And large usage quantity, cause waste.
Chinese patent 02136714.0 disclosed edible white pigment and preparation method; By (weight ratio) 45-50 titanium white powder; 18-21 sodium carboxymethylcellulose (CMC-Na) aqueous solution; In 28 or 31 D-sorbite, maltose alcohol, xylitol, oligomeric maltose or the xanthans one or more (dispersant); 0.4-1 Si Pan, fatty alcohol list monoglyceride, fatty alcohol diglycerol acid esters or sucrose fatty ester in one or more (emulsifying agents), 0.9 or 2.0 propane diols, micro-nipagin esters anticorrisive agent is formed.This antholeucin liquid is attempted to form colloid through adding more a large amount of sugar, improves the suspension of titanium white powder with this.Yet a large amount of sugar that use not only make product viscosity too big, use batching to be difficult to disperse, and same influence is used, and adds more a large amount of sugar, also do not meet the modern few sugar or the sugarfree foods tendency of the day.Owing to be added with more a large amount of viscosity sugar, must add the anticorrisive agent that is unfavorable for healthy composition in addition.Besides, this antholeucin, supplementary product consumption is too much, and the cost height is unfavorable for promoting.
Chinese patent 200610016672.7 disclosed water repelling soliquoid of nano TiO 2 and preparation method thereof; Comprise: 1) the sodium metnylene bis-naphthalene sulfonate aqueous solution 10-50 milliliter with 0.5-10.0% concentration mixes, stirs with 3-6 gram nano titanium oxide, until complete wetting; 2) be that a kind of in Sodium Polyacrylate, sodium metnylene bis-naphthalene sulfonate and the lignin sulfonic acid dipersant of 0.1-20% or several are dissolved in the distilled water with concentration, stir; 3) incite somebody to action the nano titanium oxide paste of complete wetting, join in the dispersant solution, got suspension in 30 minutes with the high-shearing dispersion emulsifying machine dispersed with stirring.This emulsion is mainly used in fields such as weaving, coating, pottery, environmental protection, and can not be used for food.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of sugar part few, auxiliary material is few, and cost is low, does not contain anticorrisive agent, and viscosity is little, good dispersion, and can be used for the liquid white element of food and medicine.
Another object of the present invention is to provide a kind of above-mentioned food and medicine with the plain preparation method of liquid white.
The present invention's first purpose realizes that main the improvement is to adopt potassium polyphosphate, sodium salt and mixed with propylene glycol dispersant, makes proportion much larger than the titanium white powder of water and organic alcohol, can in water or organic alcoholic solution, evenly disperse, and processes suspension.Specifically, liquid white of the present invention is plain, it is characterized in that the titanium white powder by 30～70wt%; 1～5wt% cellulose family or maltose and/or sucrose; The potassium polyphosphate of 2～10wt%, sodium salt and propane diols dispersant, 0.01～1wt% polyethylene glycol emulsifying agent, excess water or organic alcohol mix to be formed.
Liquid white of the present invention is plain, if be used for food and medicine, and food-grade or pharmaceutical grade that raw material should select suitable food and medicine to use.
Cellulose family among the present invention as adhesive, for example can be sodium cellulose glycolate, HPMC.
Potassium polyphosphate, sodium salt dispersant, test show the calcium ions and magnesium ions in can the complexing running water, can effectively prevent to cause autohemagglutination to sink with the titanium white powder particle charging in the calcium ions and magnesium ions in the running water, make in running water, to be difficult for sinking.For example can be PTPP, sodium salt, hexa metaphosphoric acid potassium, sodium salt.
Propane diols in water-soluble process, has changed the surface tension of water, also helps the suspension of titanium white powder particle, and has bacteriostasis simultaneously.
The mixing of two kinds of dispersants is used, and has effectively improved the suspension of titanium white powder, can make comparatively steady suspension.Two kinds of dispersants can mix with non-vanishing any ratio, all have the suspension that improves titanium white powder, and just the propane diols consumption need stir through increase and improve its suspension more after a little while.Consider economy, process the titanium white powder aqueous solution, potassium polyphosphate, sodium salt and mixed with propylene glycol ratio, a kind of 4-6 that is preferably: 1.
The preparation that liquid white of the present invention is plain; It is characterized in that respectively the cellulose family of proportional quantity or maltose and/or sucrose, potassium polyphosphate, sodium salt dispersant are dissolved in water and process the aqueous solution; It is even to merge two aqueous solution; The titanium white powder, propane diols, polyethylene glycol, aqueous solvent or the organic alcohol that add proportional quantity grind evenly, and Homogenizing pump evenly mixes.
Liquid white of the present invention is plain, owing to adopt potassium polyphosphate, sodium salt and two kinds of dispersants of propane diols simultaneously, acts synergistically each other; Make proportion much larger than the titanium white powder of water and pure fatsolvent, can process its steady suspension, the gained liquid white is plain; Used auxiliary material and sugar part are few, and evenly dispersion suspension property is good, and viscosity is little; Only about 2000, and without anticorrisive agent, cost is low.The gained liquid white is plain, the liquid that is creamy white, and the semifluid shape can evenly disperse in pure water, can in running water (comprising hard water), evenly disperse again, can also be in the fine even dispersion of fat-soluble solution; Leave standstill 1 month not stratified, put into water on a small quantity, automatically disperse, water is milky white suspension liquid, does not have deposition and separates out.And because good dispersion, easy to use, consumption is few, can practice thrift the titanium white powder consumption.Liquid white of the present invention is plain, makes dispersant because of using polyphosphate, in fluid product, can check out polyphosphate, and this is to differentiate that product of the present invention is different from a discrimination method of additive method products obtained therefrom.
Below in conjunction with several specific embodiment, further specify the present invention.
