The disclosure relates to liquid cream and the method for preparing the liquid cream.The liquid cream can be added in any suitable beverage with a certain amount of, and this amount is enough to offer beverage and becomes breast effect (creaming effect).Become the breast effect to give and cream or the relevant characteristic of breast, local flavor, tissue, texture and/or the color of for example being satisfied with (luminous or adjust to white).In selectable embodiment, the liquid cream is stable and has overcome in refrigerated storage temperature (for example ~ 4 ℃), room temperature (for example ~ 20 ℃) and the temperature (for example ~ 30 to 38 ℃) that the raises problem of phase separation in the storage process (for example creaming of emulsion, obstruction, gelling, solidify, deposition etc.) down.Stable liquid cream can have shelf life stability, for example, under 20 ℃ at least 9 months, 30 ℃ following 6 months, and following 1 month at 38 ℃.This class I liquid I cream can be described to O/w emulsion usually, has water-based continuous phase and oiliness decentralized photo.
Find that surprisingly the special combination of the glue component of special scope and weight ratio, protein, emulsifier system and oil has significantly improved the physical and chemical stability of liquid cream.For example, the special combination of these components provides stable liquid cream, and the time cycle that this liquid cream is gone through prolongation has good stability of emulsion and controlled viscosity under different conditions of storage, and is not separated.
The time cycle (for example at least 1 month) that means with a kind of state or condition maintenance prolongation " stablized " in term used herein, has minimum being separated (for example creaming of emulsion, deposition, aging gelling).When keeping at least 1 month, can find that the stable liquid cream of embodiment of the present disclosure is stable, and stablize 2 to 3 months or longer usually, and not have emergence, flocculation, sedimentation problem.
Stable liquid cream in the embodiment of the present disclosure can also be easy to be dispersed in the coffee, and is stable in the sour environment of hot and cold, and do not sprout wings, destroys emulsion, de-oiling, flocculation and deposition.In the time of in being added to coffee, tea, cocoa or other fluid product, the liquid cream can provide height to adjust to white ability, good mouthfeel, strong texture (full body), the tissue of exquisiteness and good local flavor, and peculiar smell do not occur in the storage time.The liquid cream can use with other numerous food (such as grain), as the cream of the cream of berry, soup and be used for a lot of culinary application.
In general embodiment; The disclosure provides the liquid cream, and it is that about 0.5% to about 2.5% protein, emulsifier system (mixture and the weight range that comprise at least two kinds of emulsifying agents are about 0.2 to about 0.7%) and weight range are about 8% to about 20% oil that described liquid cream has glue component (comprise weight ratio and be about 1:2 extremely the kappa carrageen glue of about 1:6 and the mixture of ι carrageenan), weight range.Emulsifier system: protein: the weight ratio of glue component can be respectively (2-14): (5-50): 1.
In one embodiment, the glue component comprises weight ratio and is about 1:2.5 extremely the kappa carrageen glue of about 1:4 and the mixture of ι carrageenan.In another embodiment, emulsifier system comprise at least two kinds of emulsifying agents mixture and weight range for accounting for liquid cream about 0.3 to about 0.6%.
In one embodiment, the weight range of glue component is about 0.05% to about 0.10%.Protein can be casein, casein sodium, Caseins, potassium salts, calcium caseinate, soybean protein, pea protein, lactalbumin or its combination.
Emulsifier system can comprise the combination of at least two kinds of low molecular weight emulsifiers of special weight ratio.The type of emulsion can be controlled through emulsifying agent, and emulsifying agent should dissolve in continuous phase.For stable O/w emulsion, the emulsifying agent that has high hydrophil lipophil balance (" HLB ") the value usually stability that should offer the best.Yet, find to have the best stability of emulsion that the liquid cream is provided under the special weight ratio that is combined in low and medium HLB value emulsifying agent of low molecular weight emulsifier of low and medium HLB value surprisingly.
Hydrophily is different in emulsifying agent with lipophilicity, and balance between the two is called the HLB value.The HLB value is to measure through the hydrophilic or lipophilic value of the zones of different of calculating molecule.The HLB value has been discussed in a plurality of references.Instance is Griffin WC: " Classification of Surface-Active Agents by ' HLB; ' (according to the surfactant classification of HLB) " Journal of the Society of Cosmetic Chemists 1 (1949): 311; Or Griffin WC: " Calculation of HLB Values of Non-Ionic Surfactants (calculating of the HLB value of nonionic surface active agent); " Journal of the Society of Cosmetic Chemists 5 (1954): 259 incorporates it into this paper as a reference.The HLB value scope of emulsifying agent is generally 0 to 20.
Low HLB value scope is about 1 to about 5.Medium HLB value scope is about 5 to about 10.The low molecular weight emulsifier of low HLB value can include but not limited to monoglyceride, two glyceride, acetylizad monoglyceride, sorbitan trioleate, glyceryl dioleate, Arlacel-65, propylene glycol monostearate, glycerin mono-fatty acid ester and monostearate, and they alone or in combination.The low molecular weight emulsifier of medium HLB value can include but not limited to the diacetylation tartrate of Arlacel-80, PGML, Arlacel-60, stearoyl-2-calcium lactate, dehydrating glycerin sorbierite list palm fibre acid esters, soybean lecithin and monoglyceride, and they alone or in combination.
In one embodiment, emulsifying agent is diacetyl tartrate (" TMG ") or its combination of monoglyceride (" MG ") with special low or medium HLB value, two glyceride (" DG "), monoglyceride.The emulsifying agent of further finding special weight ratio obtains advantages of excellent stability.In one embodiment, the weight ratio between MG and the DG can be respectively about 7:1 to about 9.5:1.In another embodiment, the weight ratio between MG and the TMG can be respectively about 1:2.5 to about 1:4.5.
In one embodiment, oil comprises one or more vegetable oil.Oil can provide creaminess (creaminess) and mouthfeel for cream.Oil can also be participated in the effect of adjusting to white of cream.Vegetable oil can comprise the oil of partially or completely hydrogenation, and they alone or in combination.For example, vegetable oil can include but not limited to soybean oil, coconut oil, palm oil, palm oil level branch, cotton seed oil, Tower rape oil, olive oil, sunflower oil, safflower oil or its combination.Sunflower oil can be the sunflower oil of high oleic acid.Oil can mix with any suitable amount and mode, to guarantee maximum oxidation stability.For example, oil can comprise the mixture of the vegetable oil that contains no more than 65% saturated fatty acid.In one embodiment, the mixture of vegetable oil comprises no more than 1% trans-fatty acid.
Oil is the key component of decentralized photo in the emulsion.In one embodiment, the average diameter of oil droplet is less than 0.6 micron.Preferably, the diameter range of oil droplet is about 0.25 micron to 0.45 micron.The oil droplet of the emulsion of this scope granularity provides the best effect of adjusting to white.
In one embodiment, the liquid cream is got rid of cellulose.For example, need not to use any cellulose components (for example microcrystalline cellulose and carboxymethyl cellulose) can prepare the liquid cream.
In one embodiment, the liquid milk spermatophore contains buffer.When being added to the sour environment (for example coffee) of heat, buffer can be avoided the creaming of emulsion or the deposition of undesirable cream.Buffer can be for example monophosphate, diphosphate, sodium carbonate and sodium acid carbonate, potash and saleratus or its combination.More particularly, the limiting examples of the buffer that is fit to is a salt, for example potassium phosphate, dipotassium hydrogen phosphate, potassium dihydrogen phosphate, sodium acid carbonate, natrium citricum, sodium phosphate, sodium hydrogen phosphate, sodium dihydrogen phosphate and sodium tripolyphosphate.Buffer can exist with about 0.5 to about 1% the amount that accounts for liquid cream gross weight.
In one embodiment, the liquid cream can comprise a certain amount of brightening agent, and the amount of described brightening agent is enough to provide further adjusting to white of aqueous medium that the liquid milk finishing is gone into.For example, brightening agent can be TiO 2, it can exist with about 0.1% to about 1% the amount that accounts for liquid cream weight.TiO 2Can have scope and be about 0.1 to about 0.7 micron granularity, embodiment preferred has 0.4 micron granularity.Work as TiO 2Be used as when replenishing brightening agent, in the liquid cream shelf life, TiO 2Can keep complete suspendible.Can also use the brightening agent that other is fit to, for example calcium carbonate, calcium sulfate and aluminium oxide.
In another embodiment, the particle size range of brightening agent is 0.3 to 0.5 micron.When the light scattering generation is the whitest, obtain the brightening agent of optimum size.This is relevant with the wavelength of being considered, and for whole visible spectrum, and optimum size is the half the of mean wavelength or about 0.30 micron.Can be contemplated that smaller szie will make liquid cream self blue partially, and more large scale will reduce the ability of adjusting to white gradually.At least it should be favourable on two reasons, using average about 0.30 micron granularity.The ability of adjusting to white that strengthens cause identical final color required adjust to white component still less, it can reduce cost.Littler particle is easier to suspendible and keeps suspendible.Generally speaking, according to the gravity that the sedimentation trend is provided, the particle of suspendible receives the influence of Stokes law critical speed.Yet when granularity during less than about 2.0 microns, other power becomes significantly and also controls sedimentation or suspendible.As everyone knows, occupy advantage less than 2.0 microns Brownian motions, and gravity becomes more and more inessential when size reduces, thereby help short grained suspendible, and do not have a lot of sedimentations.
The liquid cream can also comprise one or more compositions, for example essence, sweetener, colouring agent or its combination.Sweetener can comprise for example sucrose, fructose, dextrose, maltose, dextrin, levulose, Tagatose, galactolipin, corn-syrup solids and other natural or artificial sweetening agent.Sugar-free sweetener can include but not limited to sugar alcohol, glucidtemns of maltitol, xylitol, sorbierite, erythrite, sweet mellow wine, isomalt (isomalt), lactitol, hydrogenation etc. for example, and they are alone or in combination.
The application level of essence, sweetener and colouring agent alters a great deal, and will depend on following factor, for example the required sugariness of the effectiveness of sweetener, product, level and the type and the cost consideration of used essence.In the liquid cream, can use the combination of sugar and/or sugar-free sweetener.In one embodiment, sweetener is present in the liquid cream with about 20% concentration range to about 50% weight.In another embodiment, the weight range of sweetener is about 25% to about 35%.
In another embodiment, the disclosure provides the method for preparing stable liquid cream.Advantageously, in selectable embodiment, stable liquid cream can have under 20 ℃ 9 months at least, 30 ℃ following 3 months and at 38 ℃ of following physical and chemical stabilities of 1 month, their required character has no rotten.
