Description

  The present invention relates to powdered fats and oils, milk substitutes using the same, and methods for producing the same.

  In the production of larvae such as calves, piglets, and goats, and the breeding of other larvae, it is widely practiced to feed artificial milk instead of breast milk. This milk substitute is made mainly of skim milk powder, dry whey and other milk components, and is blended with oils, sugars, cereals and the like, and is supplied after dissolved or emulsified and dispersed in water or hot water. Milk substitutes containing a large amount of fats and oils are high in calories and can promote early growth, but have low solubility and dispersibility in water and hot water, a large fat globule diameter, and poor emulsion stability. There have been problems of causing separation of oils and fats and poor digestibility and causing diarrhea. In addition, since the fats and oils are repeatedly melted and consolidated due to the temperature difference during storage, the fats and oils ooze out and the powders are solidified.

Therefore, in order to solve such a problem, a method for producing a milk replacer in which liquid oil is sprayed on a powder raw material mainly containing a milk component and granulated has been reported (Patent Document 1), but still emulsification stability. The oils and fats are separated when dispersed and dissolved. In addition, a method of granulating powder oil and fat with other powder raw materials in advance is known (Patent Document 2). When the milk replacer was added to water or warm water and stirred, the emulsification was broken and a phenomenon in which fat globules and the like aggregated occurred.

  The present invention has been made in view of the above-described conventional problems and situations, and is well dispersed and dissolved in water and warm water without causing a charring phenomenon, excellent in emulsion stability, and solid even during storage. It is an object to provide milk replacer that does not tie.

  As a result of intensive studies to solve the problem, the inventor of the present invention produces a charring phenomenon if a powdered fat containing a vegetable oil with an ascending melting point of 10 to 20 ° C. is used as the fat mixed in the milk substitute. The present invention was completed by discovering that it was well dispersed and dissolved in water and warm water without any problems, was excellent in emulsification stability, and kept in a granular form without being consolidated during storage.

  That is, this invention solves the said subject with the powdered fats and oils characterized by containing vegetable fats and oils with a raise melting | fusing point of 10-20 degreeC.

  Moreover, this invention solves the said subject with the milk replacer characterized by containing the said powdered fats and oils.

  Furthermore, this invention solves the said subject with the manufacturing method of the milk replacer characterized by carrying out the fluidized-bed granulation of the replaceable milk powder composition containing the said powdered fats and oils.

  If milk substitutes are produced using the powdered fats and oils of the present invention, milk substitutes that are extremely well dispersed and dissolved in water and warm water without causing a charring phenomenon and that have a small fat globule diameter and excellent emulsion stability can be obtained. Can do. Moreover, this milk replacer exhibits a smooth granular shape without being consolidated during storage.

  The rising melting point of the vegetable oil used in the present invention is 10 ° C to 20 ° C, preferably 15 ° C to 19 ° C. As vegetable oils and fats, as long as their use is recognized as edible oils and fats, their raw materials and their purification levels are not limited, but for example, palm oils such as palm oil, palm kernel oil, palm olein oil, Mention may be made of coconut oil or fractionated oils thereof, and medium-chain fatty acid triglycerides. Examples of the medium-chain fatty acid triglyceride include triglycerides having a fatty acid having 6 to 12 carbon atoms as a constituent fatty acid. In this invention, you may use the said vegetable oil and fat independently, and you may adjust so that a raise melting | fusing point may be in the range of 10-20 degreeC using 2 or more types of vegetable oil and fat from which melting | fusing point differs. In addition, soybean oil and other vegetable oils can be used to adjust the rising melting point. The rising melting point in the present invention refers to the temperature at which a sample softens and begins to rise when the sample is heated in a capillary tube, and is measured according to the method described in “Standard Oil Analysis Test Method” (1996 version) shown below. can do.

Measuring method of rising melting point Sample Preparation (1) Thaw the sample and filter with dry filter paper.
(2) Attach one end of a capillary tube (inner diameter: 1 mm, outer diameter: 2 mm or less, length: 50 to 80 mm, both ends open) to a completely melted sample (usually 60 ° C.), and put the sample to a height of about 10 mm. Fill and quickly solidify with ice pieces.
(3) Leave at 10 ° C. or lower for 24 hours, or leave on ice for 1 hour, and then test.
2. Method (1) The sample-prepared capillaries are quickly brought into close contact with the lower part of the thermometer by a rubber ring or an appropriate method, and their lower ends are aligned.
(2) A thermometer (length 385 to 390 mm, mercury length 15 to 25 mm, 0.2 ° C. scale) with a capillary in close contact with a beaker filled with water at a temperature about 20 ° C. lower than the expected melting point. Immerse inside and place the lower end of the thermometer at a depth of 30 mm below the water surface.
(3) While stirring the water in a beaker (500 to 1000 mL) by an appropriate method, heat the mixture so as to increase by 2 ° C./min at first. After reaching 10 ° C. below the predicted melting point, the temperature is set to 0.5 ° C./min.
(4) The temperature at which the sample begins to rise in the capillary is defined as the melting point.

  The amount of the vegetable oil / fat is preferably 40 to 80% by mass and particularly preferably 45 to 65% by mass in the total mass of the powdered oil / fat raw material. If it is less than 40% by mass, it is difficult to satisfy calories for nutritional design, while if it is more than 80% by mass, it is difficult to make a powdered oil and fat, and storage stability tends to deteriorate.

  In addition to the above vegetable oils and fats, the powdered oils and fats of the present invention include, for example, lecithin, glycerin fatty acid esters, sucrose fatty acid esters, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene glycerin fatty acids. It is preferable to incorporate an emulsifier such as an ester. Moreover, powdered milks such as skim milk powder and whole fat milk powder; sugars, polysaccharides (dextrin, gums), silica, silicic acid, sodium caseinate and the like can be appropriately blended as necessary.

It does not restrict | limit especially as a manufacturing method of powder oil. For example, after mixing the above vegetable oil and fat with other powder oil and fat raw materials as necessary to obtain a mixed oil composition, this is homogenized using a high-pressure homogenizer, colloid mill, homomixer, etc., and then the resulting mixture Powdered fats and oils can be obtained by drying the emulsion. Examples of the method for drying the powdered oil include a spray drying method (spray drying method) using hot air, a vacuum freeze drying method, and the like. The obtained powdered fats and oils can be suitably used particularly as powdered fats and oils for milk substitutes.
The mixed emulsion for preparing the powdered fats and oils of the present invention has the fat globules obtained by dispersing and dissolving the obtained powdered fats and oils in water or warm water because the fat globules in the mixed emulsion are refined by an emulsifying action. The diameter is small and uniform. Therefore, since the milk fat milk produced using this powder has a very small fat globule diameter when dispersed or dissolved in water or warm water, a milk substitute having excellent emulsification stability can be obtained.

  The milk substitute of the present invention can be produced by subjecting the milk powder composition containing the above-mentioned powdered fats and oils to fluidized bed granulation with a fluidized bed granulation dryer or the like. In addition, the method of adding fats and oils after granulating the milk substitute material excluding powdered fats and oils by the fluidized bed granulation method in advance, the improvement of the churn phenomenon etc. compared with the milk substitutes obtained by the conventionally known methods Although accepted, it is difficult to obtain a satisfactory milk substitute.

In the milk powder substitute composition, in addition to powdered fats and oils, milk components such as powdered milk such as skim milk powder and whole milk powder, whey protein concentrate (WPC), whey such as dried whey, etc .; soybean meal, concentrated soybean protein Proteins such as wheat protein, casein, and gluten, or modified products thereof, and hydrolysates thereof; powder materials such as sugars, vitamins, minerals, seasonings, and spices can be blended. Among these, it is particularly preferable to use one or more milk components such as milk powder and whey as a main component from the viewpoints of nutrition and palatability.
The blending amount of the powdered fat is preferably 15 to 70% by mass, particularly preferably 20 to 60% by mass, based on the total mass of the milk powder substitute composition, from the viewpoints of stability and digestibility.

The fluidized bed granulation is preferably carried out by spraying water while the above milk powder composition is fluidized with hot air at 80 ° C to 120 ° C. When performing the fluidized bed granulation, a binder solution containing an emulsifier solution or dextrin may be sprayed instead of water.
3-20 mass% is preferable with respect to the total mass of a milk powder substitute composition, and, as for total amount, such as water to spray, 5-15 mass% is especially preferable.

Moreover, it is preferable to spray an emulsifier solution immediately before the drying step of fluidized bed granulation from the viewpoint of preventing adhesion to the container wall, improving dispersion / solubility in water or warm water, and defoaming effect. As another effect of spraying the emulsifier solution, it also has an effect of reducing the amount of emulsifier used.
The emulsifier solution contains 1 to 50% by mass of the same emulsifier as described above, 0.01 to 2% by mass, especially 0.1 to 1% by mass as an emulsifier, based on the total mass of the milk powder substitute composition. % Spraying is preferred.

  The milk replacer of the present invention thus obtained is calculated based on the percentage by weight passed when sieving with an air jet sieve (Air Jet sieve 200LS-N: manufactured by Hosokawa Micron Co., Ltd.) using a sieve mesh having an opening of 105 μm to 850 μm. The 50% median diameter is about 190 μm, and it has a smooth granular shape.

  The type of livestock to which the milk replacer of the present invention is fed is not particularly limited, and examples thereof include larvae such as calves, piglets, goats, and foals; and other cubs such as puppies and kittens. Suitable for larvae.
