Description
The present invention relates to a kind of stabilizing agent.This stabilizing agent can guarantee to increase the dispersion stabilization of the lactoprotein in the acidic milk drink, thereby helps to suppress the aggegation and the precipitation reaction of beverage product.
Acidified milk, sour milk beverage and acidic milk drink (it can be referred to as " acidic milk drink " hereinafter) can satisfy or adapt to that the consumer improves health and the requirement of back to nature.This class acidic milk drink can be used following method and make, that is: using lactobacillus-fermented milk or acidulating milk, and when going to pot as the casein colloidal state particle of the Main Ingredients and Appearance of milk protein (lactoprotein) in milk, casein can condense the casein particulate for the acidity of curdled milk attitude.Acidic milk drink is a kind of drink, and its fundamental component is to stir, destroy and material that these curdled milks that homogenize obtain.This beverage is generally sold on market.But, though caseic isoelectric point is about pH4.6, and consider that from the local flavor angle pH value of this class acidic milk drink or other similar drinks is adjusted to the scope of about pH3.6～4.2.Thereby when the curdled milk of these layerings was used with undisturbed situation, the dispersion stabilization of acid casein particulate was gradually reduced, and these particle coagulations form precipitation, and the quality of beverage is destroyed.
For suppressing the aggegation or the precipitation of casein particulate,, add in the drink as pectin, propylene glycol alginate and sodium carboxy methyl cellulose often with stabilizing agent.Stabilizing agent by the acid casein particulate with ionic bond, hydrophobic effect or other mode combinations, thereby help the dispersion stabilization of casein particulate.When using electronegative pectin or sodium carboxymethylcellulose, often think that doing as a whole in conjunction with the casein particulate of stabilizing agent is negative electrical charge, make casein particulate-stabilizing agent compound obtain stablizing and not taking place aggegation or precipitation by electrical charge rejection.
But various stabilizing agents all have some defectives.Pectin for example, its price fluctuates with unevenness between supply and demand, and its quality also can be because of being that natural materials changes and can not remain in same level.
In addition, as for sodium carboxymethylcellulose, though it can be as pectin quality instability, even the dispersion stabilization of lactoprotein also can be different in the drink when using the sodium carboxymethylcellulose of equal in quality standard sometimes.Therefore, need a kind of sodium salt of exploitation with carboxymethyl cellulose of stable lactoprotein dispersiveness.
About the stabilizing agent of acidic milk drink, Japanese Unexamined Patent Publication No No.161450/1993 (JP-A-5-161450) proposes to use the stabilizing agent of a kind of sodium carboxymethylcellulose as acidic milk drink.The solution viscosity of this sodium carboxymethylcellulose 2% is 10-800mPa.s.Substitution value is 0.65-1.00, and the standard error that substituting group distributes in the DEXTROSE ANHYDROUS is not more than 12.0, and unsubstituted glucose molecule is no more than 5.5 in per 1,000 glucose molecule.
But even use this sodium carboxymethylcellulose, the dispersion stabilization of lactoprotein still can not reach with regard to the stable dispersion with regard to the fluctuation of casein particulate with for a long time.In addition, make sodium carboxymethylcellulose possess above-mentioned characteristic and be difficult to, be very difficult to especially reach that unsubstituted unit is no more than 5.5 in per 1,000 glucose unit.

CMC can be used as the various stabilizing agents that contain the acidic milk drink of milk component, as milk, skimmed milk power or Other Drinks.These beverages comprise the leben by the fermented milk preparation, by adding acidulant (souring agent) and regulate the acid drink that the pH value is made to unfermentable milk.The preparation method of acidic milk drink or the kind of raw material there is not particular determination.Preferred acidic milk drink comprises as leben, and this class leben can be sterilized.Leben comprises as yogurt (yoghurt), leyen, acidified milk (kefir), skimmed milk, bioghurt Bulgarian milk, by the lactic acid drink of lactobacillus-fermented and so-called leben or the like.
As for acidulant, various edible organic acids can use, and comprise acetate and other organic carboxyl acids, citric acid, lactic acid, tartaric acid and other hydroxycarboxylic acids and similar organic acid.In the reality, available citric acid or similar acids are made acidulant.The pH value of acidic milk drink can be selected in a scope of not destroying local flavor, as about 3.5-4.3.
Can add honey or other sweeteners, vitamin, amino acid, mineral, string, spices, fruit juice and other additives in the acidic milk drink.
The consumption of CMC can be selected in the scope of guaranteeing to increase the dispersion stabilization of lactoprotein in the acidic milk drink, as with the acidic milk drink gross weight being the about 0.01-1.5 weight of benchmark % (as about 0.1-1.5 weight %), 0.1-1.0 weight % (as about 0.1-0.8 weight %) preferably approximately, more preferably about 0.1-0.5 weight %.The part by weight that adds CMC in the milk solids is, to the milk solids of 100 parts of weight, as about 0.3-40 part weight (as about 1-30 part weight), preferably approximately 3-20 part weight, more preferably 3-15 part weight.The amount of CMC in adding acidic milk drink can not make acidic milk drink reach fully stable very little the time, adds the aggegation of milk solids or the effect of precipitation then may take place when too much sometimes.
Can possess the CMC of above-mentioned feature with the conventional method preparation, its preparation process does not have particular determination.For example: CMC can following method prepare: (1) a kind of method may further comprise the steps, make NaOH in moisture organic solvent, act on cellulose and form alkali cellulose, and in the alkali cellulose that obtains, add monochloracetic acid (a kind of etherifying agent) and make under alkali condition etherification takes place; (2) a kind of method comprise make NaOH and-chloracetic acid acts on cellulose, wherein act on glucose unit with NaOH with respect to glucose unit molar excess number, the alkali cellulose of gained neutralizes with the acid ingredient of the monochloracetic acid that has contained the carboxymethylation aequum, and etherification is then carried out in the pH value being maintained neutral environment.
In the reality, method (1) can be carried out as follows, the required alkali and the ratio of etherifying agent usually in the scope of [alkali]/[etherifying agent]=2.0-2.3 (molal quantity) in alkaline system, to carry out etherification.Reaction finish the back with acid as in the acetate with excessive alkali.
Method (2) helps to reduce the consumption of monochloracetic acid and promotes it fully to react the CMC that the lactoprotein particulate is had high stably dispersing performance to generate.The formation, neutralization and the etherification step that comprise alkali cellulose in the method (2).Be described below.[the generation step of alkali cellulose]
Can make alkali cellulose by cellulose and NaOH reaction.Cellulose can use wood-fibred (for example wood pulp, as soft wood pulp or hard wood pulp), seed fiber (as cotton linters and other cottons, kapok bombaxCotton, kapok kapok) and other fibers to make.Better suited fiber comprises that the slurry (beatenpulp) that stirred is as wood pulp (as: wood pulp that is made by cork or hardwood by conventional method such as sulphite process and brown paper method).
The ratio of NaOH can be selected according to the average substitution degree of the desired cellulose ether that obtains, for stoping the unnecessary waste and the side reaction of monochloracetic acid, the molal quantity of the cellulosic glucose unit of mole ratio of NaOH is many, as the former is doubly (mole) (as: approximately 1.3-4 doubly) of 1.3-5 of the latter, preferably approximately 1.5-4.5 doubly, more preferably 2-4 times, especially preferably 2-3.5 doubly.
The reaction of cellulose and NaOH is often carried out in the especially moisture solvent in solvent.Used reaction dissolvent can be mixed (organic solvent such as methyl alcohol, ethanol, n-propyl alcohol, isopropyl alcohol, n-butanols, isobutanol, t-butanols and other more rudimentary alcohols, acetone and other ketones, dioxane, oxolane and other ethers) by hydrophilic organic solvent and water.Along mentioning, when water-insoluble solvent and hydrophobic solvent coupling, it is used as aqueous solvent.Be illustrated then is that this mixed solvent can be used as the mixture of hydrophilic solvent, a kind of hydrocarbon and water as reaction dissolvent.Benzene, toluene and other aromatic hydrocarbon, cyclohexane and other alicyclic, hexane and other aliphatic hydrocarbons are typically arranged in these hydrocarbons (hydrocarbon).
Alkali cellulose can be reacted under the uniform temperature condition by cellulose and NaOH and make, as about 0-50 ℃.[neutralization procedure]
In the neutralization procedure, the reactant mixture that contains alkali cellulose is contained the acid ingredient neutralization of monochloracetic acid at least.Acid ingredient can only contain monochloracetic acid, but when comprising monochloracetic acid and other organic acids, excessive alkali can be neutralized by this organic acid, so monochloracetic acid can more effectively be used to etherification, thereby its consumption can be reduced.Organic acid comprises formic acid, acetate, propionic acid and other monocarboxylic acids, oxalic acid, butanedioic acid and other dicarboxylic acids, glycolic, lactic acid, tartaric acid, citric acid and other hydroxycarboxylic acids, methanesulfonic acid, ethyl sulfonic acid, benzene sulfonic acid, p-toluenesulfonic acid and other sulfonic acid.But these organic acids can use also coupling separately.Can be in the reality with acetate as organic acid.
Along mentioning, the part monochloracetic acid and (or) organic acid can salt form be used (as sodium salt).
The ratio of monochloracetic acid or its esters can be selected with reference to the degree of carboxymethyl etherification.Its ratio is with respect to the glucose unit molal quantity, and the former is 1-5 times (mole) (is 1.5-4 times as molal quantity) of the latter, preferably approximately is 1.5-3.5 doubly (as 2-3 doubly).
The relative scale of organic acid and monochloracetic acid is not subjected to strict restriction with regard to the capacity monochloracetic acid that is used for carboxymethylation reaction, equal about 0.01-1.0 (mole), preferably approximately 0.02-1.0, more preferably 0.05-1.0 (mole) as organic acid/monochloracetic acid.
The alkali (NaOH) that is used for the alkali cellulose preparation process can be selected according to the amount of the free alkali in the reactant mixture that contains alkali cellulose with respect to the ratio of the acid ingredient that is used for neutralization procedure, as, alkali/acid ingredient equals about 1.0-1.7 (mol ratio), preferred 1.0-1.5 (mole), more preferably 1.0-1.3 (mole), especially preferably 1.0-1.2 (mole).The acid ingredient amount that adds in the neutralization procedure is few and when having a large amount of alkali, the utilization ratio of monochloracetic acid can be destroyed.
Adding monochloracetic acid and organic acid order does not have strict demand, and any one all can add earlier.In addition, organic acid and monochloracetic acid can add simultaneously or with form of mixtures.[etherification step]
In the etherification step, etherification reaction is to remain in the reaction system of neutral range to carry out.Used " neutral range " comprises that pH value scope is that about pH5-10 (as being approximately pH6-9) pH7-10 is advisable in specification.What be accompanied by etherification procedure is the consumption of alkali, the result be reaction system by acidifying, thereby with in the acid ingredient and after, in reaction system, add alkali (NaOH) can guarantee reactant mixture not by acidifying the time etherification reaction carry out smoothly.The amount of added alkali can be selected according to the consumption of alkali, as, the molal quantity of alkali is 1.0-1.5 times with respect to the molal quantity of acid ingredient, preferred 1.0-1.3 times, more preferably 1.0-1.2 is doubly.
For stoping the side reaction of monochloracetic acid, alkali can join in the reaction system continuously, for example adds (divide several times and add) continuously or progressively.In neutralization procedure, the part monochloracetic acid and (or) when organic acid was utilized with the form of salt, the amount of alkali was just represented the ratio that relative free acid is formed, and does not comprise monochloracetic acid salt and/or acylate.
Under the normal condition, etherification reaction takes place down in 50-100 ℃ of temperature conditions according to appointment, preferred 60-90 ℃ of condition.
Based on said method, can suppress the side reaction of monochloracetic acid.Monochloracetic acid even in the relative scale of the total amount of the total amount of alkali and acid ingredient, i.e. [alkali]/[etherifying agent]=2.0 (mole) or when bigger also can efficiently be used for carboxymethylation, and the result just can obtain the CMC of aforementioned feature.
Because contain the acidic milk drink stabilizing agent that comprises CMC with property in the acidic milk drink among the present invention, it has stable quality and high dispersion stabilization.And, even the addition of CMC also can make seldom the time acidic milk drink stable.
Following embodiment is intended to illustrate in further detail the present invention, and limits scope of the present invention anything but.
