Description

Manufacturing method of food composition

The present invention relates to a food composition, more particularly a condensed milk-like composition. The present invention also relates to a method for producing a food composition, and more particularly to a method for producing a condensed milk-like composition.

Sweetened condensed milk is generally produced by dissolving sucrose in raw milk, then evaporating the water content and concentrating it 2-3 times. In addition, the water activity of sweetened condensed milk is reduced to about 0.8 to 0.9 by increasing the solid content, the growth of microorganisms is suppressed, and the storage stability is improved, so that it can be distributed at room temperature.
In the production of general sweetened condensed milk, there are many steps such as acceptance of raw milk, storage of milk, standardization, simmering, homogenization, sterilization, concentration, cooling, and seeding. In addition, equipment corresponding to these is required, and large-scale equipment / equipment may be required especially in the process of receiving raw milk, storing milk, and concentrating.

Condensed milk that is concentrated under reduced pressure or heated by adding sucrose and vegetable oil as a substitute for milk fat to reduced milk obtained by dissolving full-fat milk powder or skim milk powder in water without using raw milk for the purpose of reducing raw material costs. Dairy products are on the market at home and abroad. Various manufacturing methods have been proposed for condensed milk-like dairy products.
For example, a condensed milk-like whey composition obtained by adding water, sucrose, dextrin, milk protein concentrate, and coconut-hardening oil to liquid whey obtained as a by-product of dairy product production has been proposed. (Patent Document 1)
As a method of simplifying the manufacturing process, skim milk concentrate, skim milk powder, full-fat milk powder, and sucrose are used as raw materials and mixed with high-concentration raw materials in a multifunction tank, etc. to reduce the concentration process and be equivalent to sweetened condensed milk. A method for producing a condensed milk-like dairy product having sensory and physical properties has been proposed. (Patent Document 2, Patent Document 3)
As a method for reducing the seeding process, a production method using concentrated milk obtained by membrane-treating raw milk and removing lactose has been proposed. (Patent Document 4)

Japanese Patent No. 6012177 Japanese Patent Application Laid-Open No. 2003-199492 Japanese Patent Application Laid-Open No. 2014-226139 Japanese Patent Application Laid-Open No. 9-224566

An object to be solved by the present invention is to provide a condensed milk-like composition having the same flavor, viscosity characteristics, and storage stability by a simpler production method than the conventional condensed milk-like composition.

For the purpose of simplifying the manufacturing process, a high-concentration raw material mixing method with a reduced concentration process is applied, but if the solid content concentration similar to that of sweetened condensed milk is maintained, the amount of dissolved water decreases and powder dissolution becomes difficult. Insufficient dissolution causes poor flavor, poor structure, increased viscosity, and burning during heating. Therefore, it is necessary to use concentrated milk or skim milk concentrated milk in which milk protein is hydrated in advance, or to prepare a high-performance dissolving machine for improving solubility.
When the amount of dissolved water is increased for the purpose of improving the solubility, the solid concentration is lowered, and the flavor and properties are light and poor as compared with the conventional sweetened condensed milk. In addition, the increase in water activity promotes the growth of microorganisms and impairs storage stability. By increasing the amount of dissolved water while maintaining an appropriate solid concentration while maintaining low water activity, powder dissolution becomes easy while maintaining a condensed milk-like flavor.

The present inventors have diligently studied in order to solve the above problems, and by using sugar alcohol and concentrated milk protein powder which has been previously treated to remove lactose, the manufacturing process is simplified and the same flavor and viscosity characteristics are exhibited.

It is possible to provide a condensed milk-like composition having the same flavor, viscosity characteristics, and storage stability at the time of refrigeration and normal temperature by a simpler manufacturing method than the conventional condensed milk-like composition.

1. 1. Condensed milk-like composition (sugar alcohol)
As used herein, the sugar alcohol means a sugar having an alcohol group (OH group), which is produced by reducing a saccharide (for example, a monosaccharide, a disaccharide, etc.). By adding sugar alcohol to the condensed milk-like composition, it is possible to increase the water content while reducing the water activity, so that the solubility of the powder raw material can be improved. Further, by adding sugar alcohol to the condensed milk-like composition, it is possible to raise the water value while reducing the water activity, so that the generation of microorganisms can be prevented, and therefore the storage at room temperature becomes possible. In addition, when the solid content concentration is the same as that of sweetened condensed milk, the sugar concentration becomes high and the food becomes a high-calorie food. However, by using sugar alcohol, the total solid content can be reduced to reduce the calories. ..

The sugar alcohols that can be used in the condensed milk-like composition of the present invention are not limited to the following, but are not limited to glycerin, erythreitol, mannitol, maltitol, sorbitol, xylitol, ribitol, inositol, D-threitol, and L. -Threitol, D-arabinitol, L-arabinitol and the like can be mentioned. Considering the high solubility in water and the effect of reducing water activity, it is preferable to use one or more selected from the group consisting of sorbitol, xylitol, erythritol, and glycerin. Two or more of these sugar alcohols can be used in combination.

The amount of the sugar alcohol to be blended is not limited to the following, but is preferably 1 to 30% by weight based on the condensed milk-like composition in consideration of the flavor and physical properties of the condensed milk-like composition and the operability during production. Is 2 to 20% by weight, more preferably 3 to 15% by weight, and most preferably 5 to 10% by weight.

(Concentrated milk protein powder)
In the present specification, the concentrated milk protein powder is a powder raw material containing lactose as a main component from which lactose has been removed. In the concentrated milk protein powder, lactose is removed by means or operations such as membrane treatment. In the concentrated milk protein powder, the milk protein content can be, for example, 50-99% by weight, 60-99% by weight, 70-99% by weight, or 80-99% by weight. In the concentrated milk protein powder, the lactose content can be, for example, 0.01-8% by weight, more preferably 0.1-4% by weight. The water content of the concentrated milk protein powder can be 0-8% by weight. Concentrated milk protein powder may contain ash, lipids and the like. However, it is preferable that the content of ash and lipid is low. In this case, the milk protein content can be preferably 70-99% by weight, more preferably 80-99% by weight.

The concentrated milk protein powder that can be used in the condensed milk-like composition of the present invention is not limited to the following, but is not limited to the following, but is not limited to the following, but is not limited to the following, but is not limited to the following, but is not limited to the following. Concentrate), isolated whey protein (WPI: Whey Protein Isolate) and isolated milk protein (MPI: Milk Protein Isolate). Two or more kinds of these concentrated milk protein powders can be used in combination. It is preferable to use MPC and / or WPC.

MPC is obtained by concentrating milk or skim milk with a filtration membrane such as an ultrafiltration membrane, and pulverizing milk protein in the milk. In MPC, lactose is removed by filtration treatment. MPC is sometimes called TMP (Total Milk Protein). MPI is prepared by the same process as MPC, but MPI is obtained by further concentrating and separating only milk protein in milk by ion exchange chromatography or the like, and generally has a higher milk protein content than MPC. high.
WPC is obtained by separating lactose, minerals, and vitamins from whey and recovering and powdering whey protein. WPC concentrates and dries whey protein by treating milk-derived liquids containing whey protein, such as cheese whey and acid whey, with a filtration membrane such as an ultrafiltration membrane or a dia-filtration membrane. Manufactured by WPI is prepared by the same process as WPC, but WPI is obtained by concentrating and separating only the protein in whey by ion exchange chromatography or the like, and generally has a higher protein content than WPC.

The blending amount of the concentrated milk protein powder is not limited to the following, but in consideration of the flavor and physical characteristics of the condensed milk-like composition, 1 to 20% by weight, preferably 1 to 15 by weight based on the condensed milk-like composition.

It can be added to the condensed milk-like composition in an amount of% by weight, preferably 1.5 to 10% by weight, more preferably 1.5 to 8% by weight.

Concentrated milk, skim milk powder, whey powder, etc. that have not been treated with lactose have a high lactose content, and when the general sweetened condensed milk and solid content are combined, the lactose concentration in water is high. Therefore, when these raw materials are used, coarse crystallization of lactose becomes a problem. Therefore, a seeding step is required to suppress the coarse crystallization of lactose. Seeding is the addition of ground lactose to pre-precipitate fine lactose crystals. Lactose used in the seeding process needs to be pulverized (micronized) as a pretreatment. Further, since lactose is added at a predetermined temperature, temperature control is required and the operation is performed in an open system. Therefore, process control becomes complicated, and there is a risk of foreign matter contamination and microbial contamination.
By using the powdered milk raw material, the raw material cost is relatively low, and the raw material procurement, raw material storage, and handleability are also simplified.

By using concentrated milk protein powder together and adjusting the lactose concentration, the seeding process can be eliminated. Further, by using the concentrated milk protein powder which is a powder raw material instead of the liquid milk raw material, the concentration step can be reduced. Further, by using the concentrated milk protein powder, the process can be simplified. In addition, concentrated milk protein powder is relatively inexpensive, easy to procure, and can be stored at room temperature.

(Seeding process)
In the present specification, the seeding step is a process of precipitating fine lactose crystals by adding core lactose from the outside to prevent the formation of coarse crystals during storage or distribution process. .. The seeding step can be carried out by adding pulverized lactose to the condensed milk-like composition at a predetermined temperature and cooling to the lactose precipitation temperature (20 to 35 ° C.).

The solubility of lactose is temperature-dependent, but if it exceeds the solubility, crystallization is promoted, and if this treatment is not performed, it leads to the formation of coarse crystals. When coarse crystals are formed, the tongue becomes rough when ingested, and the texture becomes very poor.
