Benefits of technology

[0036]The present invention changes a part of amorphous lactose that is included in powdered milk and thereby it can provide solid milk that has a preferred solubility and strength and a method of making the same. Further the present invention can provide solid milk that is easy to handle in transportation and easy to measure and method of making the same.
[0037]The present invention can obtain solid milk with hard surface only by the steps of humidifying and drying such that it can control composition of solid milk by controlling nutritional component of powdered milk. The present invention can provide a method for manufacturing such solid milk.
[0038]Another object of the present invention is to provide a method for manufacturing solid milk that can prevent powdered milk from attaching to trays during the steps of humidifying and drying by changing a part of amorphous lactose that is included in powdered milk. Thus the method for manufacturing solid milk of the present invention is high productivity.
[0039]The present invention can provide a method for manufacturing solid milk that can manufacture solid milk after manufacturing powdered milk by making use of the powdered milk.

Problems solved by technology

However, it has not been easy to actually make the powdered milk into solid state and satisfy both of strength and solubility.
Namely, even if the powdered milk is made into solid state, it has been easy to break and has been hard to handle.
Furthermore, intraoral fast disintegrable tablets do not contain fat contrary to powdered milk.
Thus it is impossible to utilize the technique of high dissolubility in manufacturing intraoral fast disintegrable tablets into the method of manufacturing solid milk.
To manufacture solid milk that has sufficient strength by using such granules, which has various components as well as amorphous lactose, is difficult compared with making medicament.
Thus the methods for manufacturing medicaments are not directly used as the method for manufacturing solid milk.

Making Powdered Milk

[0139]The various powdered milk including various components as shown in table 2 were prepared from the mixture of liquid with fat, sugar, protein, milk, and mineral group added to water and executed homogenization, concentration (evaporation), and spray drying in this order.

Manufacturing of Solid Milk

[0140]In the step of humidifying compressed powdered milk, we used Combi Oven, “FCCM6”, manufactured by Fujimak Corporation as a humidifier. We maintained the temperature within the humidifier to be 65° C. and humidity of 100% RH. We kept the compressed powdered milk for 45 seconds (humidifying duration) under the condition. In the step of drying the humidified compressed powdered milk, we used an air thermostat “DK600” manufactured by Yamato Scientific Co., Ltd as a drying machine. In the step we dried the humidified compressed powdered milk for 5 second under 95° C. and humidity of 10% RH. Finally, we obtained solid milk.

Technical Effect of Amorphous Lactose in Powdered Milk, Ingredient

[0141]We manufactured several solid milks that have different amount of amorphous lactose that has composition of powdered milk 1 (total lactose 43%). These solid milks had almost the same porosity. The strength of solid milk with 15.5% amorphous lactose was as low as 8 N, and that of solid milk with 43.0% amorphous lactose was 43 N (table 3). The result of investigation by scanning electro micrometer, SEM, shows that both solid milks have different amount of bridging among granules. Generally speaking amorphous has higher solubility than that of crystalline. We estimate that steam made amorphous lactose at the surface of the compressed powdered milk dissolved once. Then the dissolved granules attached each other to form bridges to enlarge the strength of the solid milk. It shows that, in case of solid milk that has high porosity to have high solubility, when the ingredient, powdered milk, comprises amorphous lactose ...

Abstract

The object of invention is to provide solid milk with favorable solubility and enough strength and the method of manufacturing the solid milk. The solid milk of the invention has X-ray diffraction pattern of its surface area that has a main peak of 2θ=10-15° at 2θ=10-11° or at 2θ=12-13°. A method for the manufacture of solid milk comprises compressing powdered milk to obtain compressed powdered milk; humidifying the compressed powdered milk to obtain humidified compressed powdered milk; and drying the humidified compressed powdered milk to obtain the solid milk. A part of amorphous lactose at the surface of the solid milk 12 is crystallized at the steps of humidifying step and drying.

Description

RELATED APPLICATION[0001]This application is a divisional application of U.S. patent application Ser. No. 13 / 699,642, filed Nov. 23, 2012, which is a National Phase Application of International Application No. PCT / JP2011 / 003331, filed Jun. 13, 2011, which claims the benefit of Japanese Patent Application no. 2010-134612, filed Jun. 13, 2010, which are herein incorporated by references.FIELD OF THE INVENTION[0002]The present invention is directed to solid milk which is dissolved in hot water when the solid milk is drunk and the present invention is directed to the method for manufacturing the solid milk. More specifically, the present invention relates to solid milk which has preferred solubility and strength.DESCRIPTION OF THE RELATED ART[0003]Powdered milk is a food product whose life is improved by removing almost all of the necessary moisture for the microbial growth from bovine milk and the like. Since the capacity and weight decrease by removing moisture, the powdered milk can ...
