Description

This method relates to a method for producing a milk replacer composition for young animals. More specifically, it relates to a milk substitute composition to be fed to calves, piglets, lambs, and other young animals. When dissolved in warm water, hardly soluble aggregates do not adhere to the device, and the device is washed. The present invention relates to a milk replacer composition for use in juveniles having excellent solubility.

In the production of larvae such as calves, piglets, and goats, and the breeding of other larvae, it is widely practiced to feed milk substitutes that are artificially created to replace breast milk. It has been broken.
This milk substitute composition is mainly composed of milk components such as skim milk powder, dried whey, whey protein concentrate (WPC), etc., and powders or fats, sugars, grains, minerals, vitamins, antibiotics, etc. It is a granular solid, and when actually used, it is fed after being dissolved or emulsified and dispersed in water or warm water.

  This substitute milk composition uses 30 to 80% fat as fat raw material, skim milk powder, whey, casein, if necessary, sugar base materials such as dextrin and corn syrup, emulsifiers and other auxiliaries, and stabilizers. It is manufactured by mixing coated powdered fats or oils or spraying liquid oils or emulsified oils and fats on raw materials other than fats and oils.

The quality characteristics required of such a milk substitute composition are smooth and excellent in fluidity, do not solidify during storage, and dissolve quickly in warm water, but the important thing is that The milk substitute solution after dissolving the milk composition in warm water is stable, and dirt such as fats and oils does not adhere to the feeding apparatus.

However, when the conventional milk substitute composition is produced by spraying liquid fats and oils, the fats and oils are often separated when dissolved in water or warm water, or hardly soluble suspended matters may be generated. In addition, even in the case of a milk substitute composition manufactured using powdered fats and oils, a mixer attached to an automatic feeding machine that has been increasingly used in recent years, and a large-scale milk used for dissolving a large amount of milk substitute on a large farm When an electric mixer or the like is used to dissolve with a strong stirring force, fats and oils precipitate to form hardly soluble aggregates, which adhere to a bucket, an automatic baby machine, a baby bottle, or the like, making cleaning extremely difficult. These phenomena are remarkable when vegetable oils and fats are used, and are particularly noticeable in milk substitute compositions produced or stored in spring and summer when the outside air temperature is high.

Such problems in physical properties of the milk substitute composition have been conventionally solved by various methods. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-218307) proposes a milk substitute production method that has good anti-caking property and solubility using a transesterified vegetable oil. However, what is described in this document is only the dispersibility of the milk substitute composition in warm water, and there are not so many measures taken to prevent oil stains and aggregates when the milk substitute composition is vigorously stirred. In fact, no solution has been proposed.
JP 2005-218307 A

  The present invention uses vegetable fats and oils, has excellent anti-caking property and fluidity, and hardly soluble aggregates do not adhere to the device when dissolved in warm water, facilitating device cleaning. It is an object of the present invention to provide a very good milk composition for larvae.

As a result of intensive studies to solve the above-mentioned problems, the present inventors, as an oil and fat component, (i) a vegetable mixed oil and fat using 50% or more of palm oil having an iodine value of 55.0 to 67.0, ( (B) containing 50% or more of vegetable oil or fat mixed with palm oil, palm kernel oil, or mixed oil or fat thereof, or (c) fractionated oil or fat of palm oil, and palm kernel oil or palm Oil, or vegetable mixed oil containing 50% or less of those mixed fats and oils, when the content of palm kernel oil, coconut oil, or mixed oils thereof is A%, The dairy substitute milk composition containing any one of the vegetable mixed fats and oils having a value of (55.0-0.05A) to 55.0 has anti-caking property and fluidity. Excellent and hardly soluble aggregates adhere to the device when dissolved in warm water Not, it is easy instrument cleaning, found to be very good young 畜用 milk substitute composition solubility, the present invention has been completed based on these findings.

According to the present invention, vegetable oils and fats are used, so that hardly soluble aggregates do not precipitate even when strongly stirred during dissolution, and hardly soluble aggregates do not adhere to feeding devices when dissolved in warm water. It is possible to obtain a dairy substitute milk composition having excellent solubility and facilitating instrument cleaning.

The invention of the present application is as follows: (i) Vegetable mixed oil or fat using 50% or more of palm oil having an iodine value of 55.0 to 67.0, (b) palm oil, palm kernel oil, or those Contains 50% or more of vegetable mixed fats or oils that contain 50% or more of mixed fats and oils, and contains 50% or less of palm kernel oil, coconut oil, or mixed fats and oils thereof. When the content of palm kernel oil, coconut oil, or the mixed fats and oils thereof is A%, the iodine value of the mixed fats and oils of palm oil is (55.0-0.05A) to It is a milk composition for larvae containing any one of the vegetable mixed fats and oils of 55.0.

In the present invention, low melting point fraction oils and fats obtained by removing a high melting point stearin fraction containing a large amount of tripalmitoylglycerol (PPP) in vegetable oils and fats from palm oil, in particular, iodine value is 55.0 to 67.0. Milky milk substitute prepared from vegetable oils and fats using a low melting fraction oil mixture of palm oil that does not form difficult-to-aggregate aggregates even when stirred strongly during dissolution, and with warm water When dissolving, the hardly soluble aggregate does not adhere to the feeding device, and the device can be easily cleaned, and the solubility is very excellent.

Moreover, even if the iodine fraction of the palm fraction oil to be used is 55.0 or less, if the amount is sufficiently small relative to the total amount of fats and oils, it is possible to prevent the generation of aggregates during dissolution. In particular, in the case of vegetable fats and oils in which palm fraction oil has been diluted by using 50% or less of palm kernel oil or palm oil, which originally has a very low tripalmitoylglycerol content, the mixing ratio of palm kernel oil or palm oil is A%. If it is a palm fraction oil and fat whose iodine value is (55.0-0.05 * A)-55.0, generation | occurrence | production of the aggregate will not occur. Moreover, if palm kernel oil and palm oil are used 50% or more and palm fraction fats and oils are diluted, the aggregate after melt | dissolution will not generate | occur | produce irrespective of the iodine number of the palm fraction oil.

The dairy substitute milk composition in the present invention is advantageously one containing 10 to 60%, preferably 30 to 60%, of powdered oil and fat and 30 to 80% of endophyte oil or fat as a component of the powdered fat.
As the vegetable oil and fat in the present invention, it is desirable to use 50% or more of a palm fraction oil or fat having an iodine value of 55.0 to 67.0. The method for obtaining the palm fraction oil may be a single fraction or a mixture of two or more of the fraction oil that has been subjected to a fractionation process from the raw palm oil by a general method, or the refined palm oil itself. Vegetable oils and fats used in addition to palm oil include oils such as soybean oil, rapeseed oil, safflower oil, sunflower oil, rice oil, corn oil, cottonseed oil, cocoa butter, palm kernel oil, coconut oil, and fractionated oils thereof. One or more of them may be used, but considering the nutritional components and price as a milk substitute composition for larva, for this purpose, palm kernel oil, coconut oil, and their fractions are used. It is advantageous to select the oil accordingly.

  Furthermore, when the iodine value of the palm fraction oil to be used is 55.0 or less, the palm fraction oil may be diluted by adding palm kernel oil or palm oil having a low tripalmitoylglycerol content. For example, when using 50% or less of palm kernel oil or palm oil, or a mixed fat / oil thereof, the iodine value is (55.0−0.05 × A) —if the mixing ratio to the total fat / oil is A%. A palm fraction oil such as 55.0 may be selected. Regardless of the iodine value of the palm fraction oil and fat, if it is a vegetable mixed oil and fat containing 50% or more of palm kernel oil or palm oil, aggregates after dissolution do not occur and can be suitably used.

Moreover, even when performing a fractionation process after mixing fats and oils other than palm oil and palm oil beforehand, 50% of the fraction of palm oil whose iodine value is 55.0 to 67.0 is obtained for the mixed fractionated fats and oils. Or more than 50% of palm kernel oil or coconut oil, or even if palm kernel oil or coconut oil is 50% or less, What can be considered that it is an oil-and-fat structure from which an iodine value is set to (55.0-0.05A)-55.0 is desirable.

As the powdered fats and oils used in the present invention, oils and fats containing 90% or more of the vegetable mixed fats and oils described so far are generally used which are produced by a usual method. For example, skim milk powder, whey, casein, sugars, polysaccharides (dextrin, gums), and an emulsifier are dissolved in water, and then the vegetable oil and fat in which the emulsifier is dissolved are mixed, emulsified, and then homogenized by a homogenizer. This was spray-dried to prepare a powder. Moreover, the vegetable oil and fat of the said composition may be spray-granulated by the normal method to the milk substitute material, and a granular form may be shown.

The dairy substitute milk composition of the present invention also includes skim milk powder, whey protein concentrate (WPC), dried whey, sugars, minerals, vitamins and the like as a milk substitute ingredient normally used for larval milk substitutes. A shaping material, an emulsifier and the like are used, and the amount used is not different from that of a normal one.

Hereinafter, although the milk composition for larvae of the present invention will be described in more detail using examples, the present invention is not limited to these.
Example 1
Table 1 shows the mixing ratios and iodine values of the vegetable mixed fats of each Example and Comparative Example. Table 2 shows the powdered fat composition, and Table 3 shows the milk substitute composition.

The mixing ratio of the vegetable oil mixture of Example 1 was 30% by weight of refined palm oil (Nichiyu Solution Co., Ltd.) having an iodine value of 52.5 and palm olein oil (Nichiyu Solution Co., Ltd.) having an iodine value of 56.3. )) Was 70% by weight. In addition, as shown in Table 2, the powdered fats and oils blended were crude lecithin (manufactured by ADM), sorbitan fatty acid ester (Daiichi Kogyo Seiyaku Co., Ltd.) and polyoxyethylene sorbitan fatty acid ester (Daiichi Kogyo Seiyaku Co., Ltd.). ) Was prepared. Moreover, skim milk powder (Snow Brand Milk Products Co., Ltd.) was used as a coating base for powdered oils and fats.

48.5% by weight of the above vegetable mixed fat / oil is prepared with respect to the weight of the powdered fat / oil, heated to 60 ° C., then lecithin 1.0% by weight, sorbitan fatty acid ester 0.5% by weight, polyoxyethylene sorbitan fatty acid ester 0.1 wt% was added to the heated vegetable mixed fat and oil, and mixed well to prepare a fat and oil mixture containing lecithin and an emulsifier.
On the other hand, 50 parts by weight of the above skim milk powder is mixed and dissolved in 100 parts by weight of warm water at 60 ° C., and the 60 ° C. vegetable mixed oil / fat composition prepared above is further added. And mixed to prepare an O / W mixed emulsion solution.

The obtained mixed emulsion solution was subjected to homogenization by applying a pressure of 200 kg / cm ² with a high-pressure homogenizer 15MR-8TA (APV GAULIN Inc). The diameter of the fat globules in the homogenized mixed emulsion was measured using an optical microscope, and it was confirmed that the fat globules in the emulsion were refined by the homogenization. It was.
The homogenized mixed emulsion was spray-dried with hot air at 180 ° C. using a Niro Co. Ltd. Mobile Minor (Niro Co. Ltd.).
The powder obtained after spray drying was spread thinly on a vat and allowed to cool overnight at room temperature to produce a powdered fat composition having a crude protein content of 15.5% and a fat content of 49%.

Using the powdered oil / fat composition obtained by the above method, the milk composition for milk substitute shown in Table 3 was prepared.

Each raw material shown in Table 3 was sufficiently mixed with a universal mixer until uniform, and a mixed powder having a crude protein content of 25% and a fat content of 21% was prepared.
6 kg of the prepared mixed powder is put into a fluidized bed granulator (MGD-0.5, manufactured by Okawara Seisakusho Co., Ltd.), and water at room temperature (about 25 ° C) is added while flowing the mixed powder with hot air of 90 ° C. Spray granulation was carried out at a spraying speed of 50 g / sec. Spraying was performed until the total amount of water sprayed was 450 g, that is, 7.5% based on the weight of the mixed powder. After completion of water spraying, the mixture was further dried for 10 minutes and then discharged from the fluidized bed.
The obtained granulated material was spread thinly on a vat, cooled in a refrigerator at 4 ° C. for 1 hour, sieved with a sieve having an aperture of 1.4 mm, and sieved to obtain a milk substitute composition. The appearance of the milk substitute composition was smooth and granular.

The milk substitute composition 65 g was subjected to a deterioration treatment due to temperature change for solubility evaluation. A prototype milk composition 65 g was placed in a thermostat with a program, heated at 35 ° C. for 3 hours, and then cooled at 5 ° C. for 3 hours, and the sample was taken out 8 times.
The substitute milk composition subjected to the deterioration treatment was evaluated for solubility with an automatic baby machine (model TAP5-SA2-30-P, Roll Create Co., Ltd.). First, 500 ml of 43 ° C. warm water was put in a dissolving pot of an automatic baby machine, and then 65 g of the milk substitute composition that had been subjected to deterioration treatment was poured therein, and the mixer was rotated to vigorously stir for 2 minutes to dissolve the milk substitute. After stirring, the dissolved milk substitute solution was poured into a 0.5 mm sieve and the residue was confirmed. As shown in FIG. 1, no agglomerates were observed on the sieve, and the fat and oil to the dissolution pot There was no contamination.

Example 2
The mixing ratio of the vegetable oil mixture of Example 2 was 18% by weight of refined palm oil similar to that used in Example 1, 42% by weight of palm olein oil, and refined palm kernel oil (Nichiyu Solution Co., Ltd.). ) Was 40%. Using this vegetable mixed oil and fat, a powdered oil and fat and a milk composition for milk substitute were produced by the same mixing ratio and method as in Example 1.
When this milk replacer composition was subjected to deterioration treatment with a temperature difference in the same manner as in Example 1, and then stirred strongly with an automatic baby machine, as in Example 1, as shown in FIG. Etc. were not confirmed at all, and there was no adhesion of fat and oil stains to the dissolution pot.

Example 3
The mixing ratio of the vegetable oil mixture of Example 3 was 20% of refined palm oil similar to that used in Example 1, and Palm Ace 10 (non-refining fraction oil having a iodine low value of 67.0) Nichi Oil Co., Ltd.) was used 80%. Using this vegetable mixed oil and fat, a powdered oil and fat and a milk composition for milk substitute were produced by the same mixing ratio and method as in Example 1.
When this milk replacer composition was subjected to deterioration treatment by applying a temperature difference in the same manner as in Example 1, it was agitated with an automatic baby machine, and as in Example 1, as shown in FIG. Nothing was confirmed, and there was no oily dirt adhered to the melting pot.

From the results of Examples 1 to 3, if 50% or more of the vegetable oil mixture is used, the composition of the palm fraction oil and fat mixed with palm oil, palm olein, palm ace 10 and the like is adjusted to an iodine value of 55.0 or more. It can be seen that the milk replacer composition has excellent solubility without causing agglomerates and dirt on the pot. At this time, as can be seen from the case of mixing fat and oil other than palm fraction fat and oil, for example, palm kernel oil (iodine number 18.6) as in Example 2, the iodine value of fat and oil other than palm fraction fat and oil is Since it is very low, the iodine value of the whole vegetable mixed fat may be less than 55.0. However, in this example, regardless of the iodine value of the whole vegetable mixed fat and oil, by using the palm fraction fat and oil having an iodine value of 55.0 or more, as shown in FIG. It is shown that a milk replacer composition without odor is obtained.

Example 4
As for the mixing ratio of the vegetable mixed fat of Example 4, 40% of refined palm oil similar to that used in Example 1 and 60% of refined palm oil (Fuji Oil Co., Ltd.) were used. Using this vegetable mixed oil and fat, a powdered oil and fat and a milk composition for milk substitute were produced by the same mixing ratio and method as in Example 1.
When this milk replacer composition was subjected to deterioration treatment by applying a temperature difference in the same manner as in Example 1, it was agitated with an automatic baby machine, and as in Example 1, as shown in FIG. Nothing was confirmed, and there was no oily dirt adhered to the melting pot.

Example 5
The mixing ratio of the vegetable oil mixture of Example 5 was 30% of refined palm oil similar to that used in Example 1, and 70% of refined palm kernel oil similar to that used in Example 2. . Using this vegetable mixed oil and fat, a powdered oil and fat and a milk composition for milk substitute were produced by the same mixing ratio and method as in Example 1.
When this milk replacer composition was subjected to deterioration treatment by applying a temperature difference in the same manner as in Example 1, it was agitated with an automatic baby machine, and as in Example 1, as shown in FIG. Nothing was confirmed, and there was no oily dirt adhered to the melting pot.

Example 6
The mixing ratio of the vegetable mixed fat of Example 6 is 42% of refined palm oil similar to that used in Example 1, 28% of palm olein oil, and the same refined palm as used in Example 4 30% oil was used. Using this vegetable mixed oil and fat, a powdered oil and fat and a milk composition for milk substitute were produced by the same mixing ratio and method as in Example 1.
When this milk replacer composition was subjected to deterioration treatment by applying a temperature difference in the same manner as in Example 1, it was agitated with an automatic baby machine, and as in Example 1, as shown in FIG. Nothing was confirmed, and there was no oily dirt adhered to the melting pot.
From the results of Examples 4 and 5, even when palm fraction fats and oils having an iodine value of less than 55.0 are used, if palm kernel oil or palm oil is used by 50% or more and the palm fraction fats and oils are sufficiently diluted, It can be seen that there is no adhesion of agglomerates at the time of dissolution, and the dissolution pot of the automatic feeding machine is not soiled with fats and oils.

In Example 6, the use ratio of coconut oil was set to 30%. In this case, the iodine value of the palm fraction oil that does not cause agglomerate generation was calculated from the formula proposed by the inventors,
55.0−0.05 × 30 = 53.5 to 55.0
It must be within the range. On the other hand, the iodine value as a palm fraction fat calculated from the mixing ratio of refined palm oil and palm olein was 54.0, and no aggregates were actually generated. Thus, even if the fat content other than the palm fraction oil such as palm oil is 50% or less, if the iodine value of the palm fraction fat is within the range of the mathematical formula proposed by the inventors, when the substitute milk is dissolved Aggregation does not occur.

Comparative Example 1
100% of refined palm oil similar to that used in Example 1 was used as the mixing ratio of the vegetable mixed fat of Comparative Example 1. Using this vegetable mixed oil and fat, a powdered oil and fat and a milk composition for milk substitute were produced by the same mixing ratio and method as in Example 1.
When this milk replacer composition was subjected to deterioration treatment in the same manner as in Example 1 with a temperature difference, it was vigorously stirred with an automatic baby machine. As shown in FIG. 2, a large amount of white agglomerates were collected on the sieve. It was done. As a result of analyzing the components, 90% were fats and oils, and the rising melting point was 50 ° C. As a result of analysis of triglycerides by gas chromatography, the C48 peak indicating tripalmitoylglycerol (PPP) protruded about 3 times that of the raw oils and fats, although most of the triglyceride compositions were not different from those of the raw oils and fats. all right. For this reason, it was presumed that the aggregates were aggregates of high melting point triglycerides mainly composed of tripalmitoylglycerol and precipitated in the milk substitute solution.

Comparative Example 2
The mixing ratio of the vegetable oil mixture of Comparative Example 2 was 40% by weight of refined palm oil similar to that used in Example 1, and 60% of palm olein. Using this vegetable mixed oil and fat, a powdered oil and fat and a milk composition for milk substitute were produced by the same mixing ratio and method as in Example 1.

When this milk replacer composition was subjected to deterioration treatment by applying a temperature difference in the same manner as in Example 1, it was vigorously stirred with an automatic baby machine. As shown in FIG. 2, the size of the milk composition was about 3 to 10 mm on the sieve. Many grains of white aggregate remained. In addition, a large number of agglomerates adhered to the melting pot wall and mixer portion of the automatic feeding machine.

When Example 1 and Comparative Examples 1 and 2 were compared, the iodine value of the palm fraction fat used in Example 1 was 55.2, whereas the iodine value of the palm oil of Comparative Example 1 was 52.5. Moreover, the iodine value of the palm fraction fat used in Comparative Example 2 was 54.8. Thus, when the iodine value of the palm fraction fat was less than 55.0, it was found that aggregates were generated.

Comparative Example 3
The mixing ratio of the vegetable mixed fat of Comparative Example 3 is 55% of refined palm oil similar to that used in Example 1, 5% of palm olein oil, and refined palm similar to that used in Example 2 The core oil was 40%. Using this vegetable mixed oil and fat, a powdered oil and fat and a milk substitute composition were prototyped by the same mixing ratio and method as in Example 1.
This milk replacer composition was subjected to deterioration treatment by applying a temperature difference in the same manner as in Example 1, and then stirred vigorously with an automatic baby machine. As in Comparative Examples 1 and 2, as shown in FIG. A small amount of white aggregate was observed. Further, a slight amount of agglomerates adhered to the melting pot wall and mixer part of the automatic feeding machine.

In Comparative Example 3, the iodine value as the palm fraction oil is calculated to be 52.8 from the mixing ratio of refined palm oil and palm olein oil. On the other hand, as shown in Example 5, the use ratio of palm kernel oil is 40%. In this case, the iodine value of the palm fraction oil that does not cause the generation of aggregates is calculated from the formula proposed by the inventors. Then
55.0−0.05 × 40 = 53.0 to 55.0
However, the iodine value of the palm fraction fat of Comparative Example 3 deviates from this range. Therefore, agglomerates were actually generated after the milk substitute was melted, and the melting pot was soiled.

It is a figure which shows the filtration test result of each product by this invention. It is a figure which shows the filtration test result of each product of a comparative example.
