Description

[Detailed description of the invention] The present invention relates to a method for manufacturing a separate dressing.

Separate dressings are made by laminating a water phase raw material that uses vinegar as the main raw material and an oil phase raw material that uses salad oil as the main raw material.In order to maintain a refreshing appearance, the water phase part is transparent. Therefore, it is desirable that turbidity does not occur during storage. Therefore, for this purpose, white vinegar, which is produced by subjecting distilled alcohol to acetic acid fermentation, has been commonly used as table vinegar. However, if a separate dressing using white vinegar is packed in a container made of polyethylene terephthalate, which has good transparency, instead of the conventional glass bottle, for ease of transportation, the container can be used for cooking. When the product is shaken and left to stand still, there is a problem in that oil droplets adhere to the inner wall of the container in the aqueous phase portion, which significantly impairs the refreshing appearance. This type of oil droplet adhesion is not seen on glass containers.
This is presumably a phenomenon that occurs because polyethylene terephthalate resin has lipophilic properties. An object of the present invention is to prevent oil droplets from adhering to the inner wall of the container when the container is shaken, even when the aqueous phase raw material, which mainly uses white vinegar as vinegar, and the oil phase raw material are filled into a container made of polyethylene terephthalate. To provide a method for producing a separate dressing in which the aqueous phase part becomes cloudy during storage of the product.

As a result of various studies, the present inventor found that when a certain type of Western vinegar is mixed with white vinegar and used, the components of Western vinegar and white vinegar may subtly interact with each other. The present invention was completed based on the knowledge that the object of the above was achieved. That is, in the method for producing a separate dressing of the present invention, when producing a separate dressing by filling a water phase raw material and an oil phase raw material into a container made of polyethylene terephthalate, 8 to 9 parts of white vinegar are added to 8 to 9 parts of white vinegar as the water phase raw material. , one or more of malt pinega, apple vinegar, or wine vinegar
It is characterized by using 2 parts of vinegar added.

The present invention will be explained in detail below.

5 In the present invention, the method of producing a separate dressing by filling a container made of polyethylene terephthalate (hereinafter referred to as POIJ ester) with an aqueous phase raw material and an oil phase raw material is the same as the conventional method.

That is, a polyester container is first filled with an aqueous phase raw material in which vinegar is used as the main raw material and salt, spices, etc. are appropriately dissolved and dispersed, and then an oil phase raw material consisting mainly of salad oil is layered on top of the water phase raw material. Fill it. A normal filling machine may be used for filling. In the present invention, 8 to 9 parts of white vinegar and 1 to 2 parts of one or more of malt vinegar, apple vinegar, or wine vinegar are added as raw materials for the aqueous phase.
It is characterized by the use of added vinegar.

The types and ratios of vinegar to be used were determined by 9 parts white vinegar to 9 parts malt vinegar.
When using vinegar containing at least 1 part of apple vinegar or wine vinegar, the effect of preventing oil droplets from adhering is poor; If you use vinegar containing more than 2 parts of malt vinegar, apple vinegar, or wine vinegar, the aqueous phase during storage of the dressing may be prevented, but the adhesion of oil droplets may be prevented. This is because the parts tend to become cloudy. Malt vinegar
Apple vinegar or wine vinegar can be used alone or in combination of two or more types, but when used in combination, the total amount of vinegar used should be within the above range of 1 to 2 parts. It is necessary. Separate dressings produced in this way in polyester containers are produced by shaking the container, probably because certain vinegar components such as malt vinegar and apple vinegar make the inner walls of the polyester container non-oleophilic. There are no or very few oil droplets adhering to the inner wall of the container after completion of the procedure, and the aqueous phase hardly becomes cloudy during storage of the product.

Therefore, the separate dressing packaged in a polyester container of the present invention can be used while always maintaining a refreshing appearance.

Hereinafter, test examples showing the effects of the present invention and examples of the present invention will be described.

In the present invention, all percentages and parts are expressed on a weight basis. Test Example Separate dressings consisting of a water phase raw material and an oil phase raw material in the following proportions were produced for each of six types of vinegar in which the mixing ratio of white vinegar and malt vinegar was varied as shown on the left side of the table below.

Each of 180 units (90 units of water phase raw material, 90 units of oil phase raw material) was filled into a polyester container (cylindrical shape with a diameter of 6 cylinders) having a capacity of 200 blocks. Next, the container was shaken vigorously in a sand chamber and allowed to stand still, and the state of adhesion of the oil bottle to the inner wall of the container after 10 minutes of standing still and the presence or absence of turbidity in the aqueous phase portion after 3 months of standing still were observed. The results are shown on the right side of the table below, and white vinegar 9~
Sample 3 using 1 to 2 parts of malt vinegar to 8 parts
, 4, samples 1, 2 and 5, 6 that fall outside the range
It is understood that, unlike in the case of , no oil bottle adhesion was observed, nor was there any turbidity in the aqueous phase. Separate dressing blending ratio table Note (1) A: Indicates white pineger.

B: Indicates malt vinegar.

(2) Subheadings 10, 10 and 1 are as follows:

10: Quite a lot 10: A little: Yes (not seen) (3) When using apple vinegar or wine pinega instead of malt pinega, or even when using a mixture of these vinegars, malt vinegar The results were similar to those in the case of .

Example 1 18 parts of table vinegar, which is a mixture of white vinegar and malt vinegar at a weight ratio of 8:2, was thoroughly mixed with 4 parts of sugar, 4 parts of salt, and 23 parts of fresh water, and this mixed solution 902 was poured into a volume of 200 parts.
Fill it into a polyester container made by Suzu, then add salad oil 9.
A separate dressing packaged in a container was produced by stacking and filling the dressing.

Example 2 20 parts of vinegar, which is a mixture of white vinegar, malt vinegar, and wine vinegar in a weight ratio of 8:1:1, and 1 part of sugar.
1 part, 3 parts of common salt, and 26 parts of fresh water, 90 parts of this mixed liquid was filled into a polyester container with a capacity of 200 carp, and then 90 parts of salad oil was stacked and filled on top.
A separate dressing packaged in a container was manufactured.
