Description
SPECIFICATION
Novel emulsifier composition and quality improvement method of starch-containing food
This invention relates to an emulsifier composition, a process for its preparation and to its use as
an additive for starch-containing food.
Mono-and diglycerides are widely used as emulsifiers in the food processing industry. Their
particular function differs depending on the purity, appearance, physical and chemical properties and
the types of fatty acid which constitute the emulsifier.
In the case of starch-containing food, such emulsifiers are required to react well, particularly with
starch, and saturated fatty acid monoglycerides having 14 to 1 8 carbon atoms and of high purity
distilled monoglyceride are known to be satisfactory in meeting these requirements.
In the case of using mono-and diglycerides in the fat phase, there is no restriction on the physical
properties of mono-and diglyceride since it can be dissolved into fat. However, in the case of starch
containing food, it is desirable to use mono-and diglycerides in the aqueous phase, in order to obtain a
starch-complexing improvement effect. In these cases, or in the case where the emulsifier is used mixed
with the raw material in powdered form, the physical appearance, physical and chemical properties
such as the crystalline forms of monoglyceride and surface condition may all have significant bearing on
the functions of the emulsifier.
Monoglycerides are noted for their polymorphic forms, and these are sub -a, a, cr"Bt and p which are indicated by order of decreasing melting points. The evaluation of properties is known to be good in the
above-mentioned order as the p crystalline form is most stabilized thermodynamically, and
monoglyceride has always been marketed in the P crystalline form.
The reason why the a-crystalline form is more effective in the aqueous phase can be explained by
the difference in hydrophilic properties. As a means of obtaining the a crystalline form, there is the
conjoined crystal method with the combined use of a saturated fatty acid monoglyceride and a fatty
acid propyleneglycol ester (J. Am. Oil., Chem. 40, 725 (1963)); or a method comprising dispersion in
water at temperature below the melting point of the monoglyceride. But both of these methods have disadvantages such as small yields of the monoglyceride, difficulty in maintaining temperature control or in preservation of the product.
From these standpoints, it would be advantageous if the p-crystalline form could be found to possess stable crystallization while showing good properties. Various methods have been considered as means for improving the hydrophilic properties. In order to increase the surface area of crystallization, a method whereby minute crystals were obtained from recrystallizing by use of solvent (Japanese Patent:
TOKU-KO-SHO 50-34613) and a method whereby aqueous dispersion of the p-crystalline form was obtained by adding a stabilizer into the dispersion or dry powdered monoglyceride was obtained by adding a binders into the dispersion (Japanese Patent: TOKU-KO-SHO 44-26900) have been considered.
Each of these methods has excellent improvement effects. However, with regard to obtaining powdered monoglyceride, there was a problem because it tended to be expensive from a standpoint of production efficiency, whereas a product in paste form proved to be inferior in handling, preservation and in stability. Therefore the development of a more simplified process has long been desired for preparing a powdered monoglyceride which is effective in the aqueous phase. As a result of intensive research work we have discovered a novel emulsifier composition which exerts good quality improvement effect on starch-containing food and which is easier to handle, less expensive, has a longer preservation time and has a stable quality.
Thus, the present invention provides an emulsifier composition comprising a powdered high purity
distilled monoglyceride composed of 6585% of a saturated fatty acid monoglyceride, 35-1 5% of an
unsaturated fatty acid monoglyceride, and having an iodine value of 10 40, the composition having
been tempered for more than 30 minutes at a temperature of more than 450C without melting of the
composition. In the composition of the fatty acid monoglyceride, the saturated fatty acid preferably has
from 12 to 22 carbon atom and the unsaturated fatty acid preferably has 1 6 to 22 carbon atoms.
The composition according to the invention can be produced either by using a fatty acid material
having the acquired characteristics or by mixing two or more different kinds of fatty acid monoglyceride.
If the amount of unsaturated fatty acid monoglyceride was less than 1 5% and the iodine value
was less than 10, the desired results could not be obtained. Likewise, if the amount was more than 35%
and iodine value was more than 40, the complex-forming ability with starch deteriorates and at the
same time, it is difficult to obtain in powdered form.
According to this invention, we found that, by tempering the emulsifier composition for more than
30 minutes at a temperature which is within the range from more than 450C to a temperature which
does not melt the said composition, the properties of the composition improved drastically and the
preservation stability also improved. If the tempering temperature was below 450C, it takes a longer
time to attain the required properties and the grain sizes become coarse; therefore such a low
temperature cannot satisfy both the production and property requirements.
If fatty acid monoglyceride is solidified by cooling, it changes into the stable B-crystalline form
after undergoing successive crystal formation, from each of sub-P, a and p'. But as the transition time
became longer, the crystals thus obtained become coarser. Therefore, it is necessary to effect transition
as rapidly as possible in order to obtain minutely sized crystals in order to meet the requirements of this
invention. The most effective method is to use a solvent such as water or alcohol.
However, as indicated earlier, problems exist in handling and preservation stability.
We discovered that, from these standpoints, fatty acid monoglycerides of unsaturated fatty acids with cis coordination in the double bond position suit the purpose of this invention.
As indicated earlier, the ratios of saturated fatty acid monoglyceride and of unsaturated fatty acid monoglyceride are 6585% for the former and 35-1 5% for the latter. For complex formation with
starch, it would be more advantageous to have as high as possible content of the saturated fatty acid
monoglyceride in the mix to obtain optimum properties.
Depending on the types of fatty acids, fatty acid monoglycerides have polymorphic melting points.
However, where the difference in carbon number is four or less, it forms a solid solution. Therefore there would be little difference in handling between such a monoglyceride and a single fatty acid
monoglyceride.
As the first stage in the production of the composition according to the invention, this solid solution of a fatty acid monoglyceride is cooled to a temperature below sub-a crystal melting point,
more desirably to below 350C. In this instance, unsaturated fatty acid monoglyceride which is a minor
constituent would be solidified among the crystals of the saturated fatty acid monoglyceride. The second stage of production is a crystal transition stage obtained by tempering. The tempering temperature is desired to be above the crystal melting point of solid solution sub-a- or a that is, above 450C. This tempering process melts unsaturated fatty acid monoglyceride and saturated fatty acid
monoglyceride crystallizes in a minute form and stabilizes.In this case, the appropriate degree of tempering and the solvent effect of the unsaturated fatty acid monoglyceride accelerates the stabilizing
speed of crystal. Normal tempering would be, for example, 2-8 days at 450C and 30 minutes to one
day at 50--550C.
The third stage of the process is cooling of the tempered monoglyceride. The product thus obtained has excellent properties and is stable for a long period of time.
Among the components disclosed in this invention, fatty acid monoglyceride which is composed of cis-type unsaturnted fatty acids is, on the one hand, a good solvent and it is not very compatible with saturated fatty acid monoglycerides and does not inhibit crystallization at a low temperature; on the other hand it is largely hydrophilic even at low temperatures. Therefore, among saturated fatty acid
monoglycerides, unsaturated fatty acid monoglycerides, when added with water serve as the disintegrator, and disperse saturated fatty acid monoglycerides in the aqueous phase. Fatty acid monoglycerides which comprise trans-type unsaturated fatty acids are structurally similar to and largely compatible with saturated fatty acid monoglycerides and are believed to form a condition which is close to a solid solution state with a high melting point.Therefore, this can not be treated in a same manner as that of the cis-type.
Furthermore, the purpose of this invention is fulfilled by a larger degree by the combined use of the
monoglyceride composition mixed with less than 5% of one or more substances selected from alcohols, organic acids, lecithin and stearoyl lactylate which are compatible with fatty acid monoglyceride and optionally tempering for more than 30 minutes at a temperature which is more than 450C, without
melting the composition.
The substance which is to be used is combination with the monoglyceride of this invention, acts thermodynamically to refine crystals of saturated fatty acid monoglyceride and to form a thin film of the unsaturated fatty acid monoglyceride so that it can fulfil the purpose of invention without the need for tempering. Tempering, however, would also serve further to improve the properties.
Suitable alcohols include propylene glycol and glycerol; suitable organic acids include citric acid,
malic acid, fumaric acid, succinic acid, glutamic acid, tartaric acid and lactic acid; the lecithin may be, for
example, soybean lecithin or egg yolk lecithin; and the lactylic stearate, may be, for example, sodium stearoyl-2-lactylate or calcium stearoyl-2-lactylate.
The emulsifer composition thus obtained would exert prominent effects. But, since the product is
composed of saturated fatty acid monoglyceride, the crystal surface of which is surrounded by a thin film of unsaturated fatty acid monoglyceride, there sometimes arises problems such as caking or
stickiness is developed on the surface of handling equipments under preservation and distribution environments at certain temperatures.
We discovered that these problems could be overcome by mixing the composition with 5-20% of a fat which has a melting point which is more than the tempering temperature of the fatty acid
monoglyceride.
In a composition which is composed of a saturated fatty acid monoglyceride and an unsaturated fatty acid monoglyceride, the fat does not form a solid solution with the former, and forms a monotectic crystal so that crystallization stabilizing was accelerated. The fat was discovered to dissolve in the latter to a less degree and the crystallizing of the fat was accelerated with the solvent effect of the latter.
In a powdering process, for instance in spray cooling, air, carbon dioxide gas or nitrogen gas can be used for cooling the environment. Under such atmospheres, the fat which has a lower polarity than the fatty acid monoglyceride, would segregate on the surface of grains, and would create rapid crystallization. The powder thus obtained would have rather thick surface density, less humidity absorption and higher fluidity. In comparison to the composition made only of fatty acid monoglyceride, it would have excellent acceptance to production process, packaging and have excellent preservation stability causing no problems in the distribution channel.
The addition of the fat should be iimited to 20%. Any further addition deteriorates the properties and lessens the emulsifier content so that it would not be economical. The effect of addition would show from 5% fat, accordingly, the addition of 10% is desirable for actual application.
The fat with the melting point of more than 450C used in this invention may be, for example, hardened beef tallow, hardened lard, hardened fish oil, hardened chicken oil, hardened palm oil, hardened rapeseed oil, hardened soy bean oil, hardened coconut oil and hardened caster oil. These can be used by one kind, or mixture of more than two. The fat suited for the purpose of this invention has a melting point of more than 450C, preferably 500C, which would give the optimum results. The emulsifier composition including the fat thus obtained Could tend to be less hydrophilic compared with the composition composed only of fatty acid monoglyceride.
In food processing, it is normal that a certain degree of force is applied. But this would be of no problem.
The powdering process of this invention can be accomplished in any conventional manner, but it is efficient to melt the emulsifier composition followed by powdering process by means of spray cooling.
As to the grain size of powder, the grain size distribution is preferably 42-80 mesh. Properties deteriorate if the grain size is coarse and the ease of handling deteriorates as the grain size is finer.
Moreover, variation of the grain size from the optimum range by a small degree would not be harmful.
It is known by the results of measurement by X-ray diffraction analysis, and differential thermal analysis that the types of crystals of fatty acid monoglyceride contained in the emulsifier composition obtained by this invention are crystal for the most part and 'crystal in a minor part. Therefore, as indicated earlier, the reason for the excellent stability of properties can well be understood. For use, the emulsifier composition of this invention can be used merely by mixing with water or with a powder which is a food processing material. This illustrates the ease of handling.
Since the advantages of the properties of the emulsifier composition can be exerted principally by forming a complex with starch, its property performance can be evaluated by Blue Value (hereinafter abbreviated as BV). BV can be obtained by the reaction of iodine and starch. When the starch forms a complex with fatty acid monoglyceride, the colour of the starch is disturbed by iodine. Accordingly, the degree of complex formation, in other words, properties of the emulsifier composition can be evaluated by spectrophotometry analysis by the degree of absorbance. Therefore, the lower the BV, the more complex forming-ability, indicating the excellence of the properties.
BV of less than 0.300 as indicated in the following examples would be adequate for actual application.
The emulsifier composition of this invention is capable of improving the quality of starchcontaining food by directly adding to the starch-containing food or to the mix. This composition exerts excellent quality improvement effect in making bread, pastries, pan cake, noodles, cookies, food made from fish and livestock and the said mix. Since it exerts excellent quality improvement effects by mixing with water, comparable effects were recognized in fatty, water based foods or in protein-containing foods.
The composition is not limited to use in the aqueous phase but can also be used in fat phase.
With reference to the accompanying drawing,
Fig. 1 shows a diagram of secular change of BV by tempering the composition of this invention during its preparation.
The following Examples illustrate the invention.
EXAMPLE 1
A mixture of equivalent amounts of refined palm oil distilled monoglyceride and full-hardened palm oil distilled monoglyceride was melted and after spray-cooling, a powder with grain meridian diameter of 60 mesh was obtained. The powder was immediately placed in a tempering room at a temperature of 500C and discharged from the tempering room after a lapse of one hour when the temperature of the powder was lowered to room temperature. Thus the product was obtained. The component of fatty acids, the iodine value and BV are indicated in Table 1. These figures show excellent performance values in comparison to fatty acid monoglyceride for bread mix which was composed of untempered material and commercially available hardened oil fatty acid monoglyceride (comparison).

The test results of the product are indicated in Table 1 and the product stability test results were indicated in Table 2.
Favorable results were obtained in all cases.

Biue Value was used to measure the secular change of properties. Iodine value of this composition was 23. The results are indicated in Fig. 1.
From these test results, the improvement were not discovered at tempering temperature of 400C;
with the tempering temperature of 450C an improvement was observed after 2-8 days and at 500 C, a
drastic improvement was recognized after 30 minutes - 2 hours.
